Enable SSL in JBoss EAP 7.1

In this post I will demonstrate how to enable SSL in JBoss EAP 7.1 and I will use "" post for the demonstration purposes.

Prerequisites 

1. You should have install java 1.8 or above.
2. You should have Eclipse installed in your PC.
3. Your PC should setup Maven installed and configured.
4. MS SQL server need to be installed. 
5.  You need to have JBoss EAP instance in your PC.

Lets deploy the application 

First check out the project from GitHub repository related my my previous post "spring-boot-rest-api-with-sqlserver-2019". 

First lets enable Database user name and password on application properties by removing "#" marks in-front of spring.datasource.username and spring.datasource.password.  

#==== connect to mysql ======#
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:sqlserver://localhost;databaseName=TestDB
spring.datasource.username=nirmal
spring.datasource.password=Test123_

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.database-platform=org.hibernate.dialect.SQLServer2012Dialect
server.port = 8080

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=false
spring.jpa.properties.hibernate.format_sql=true
#==== Logging configurations ======#
logging.level.root=WARN,INFO,ERROR
logging.level.com.baeldung=TRACE

First perform maven install and generate the war as show in figure below.

Then lets start the JBoss EAP by double click on standalon.exe in windows or running standalone.sh file in linux.  When EAP starts you can see following warning message has been display in the console. 

WARN  [org.jboss.as.domain.management.security] (MSC service thread 1-7) WFLYDM0111: Keystore G:\Programs\Servers\jboss-eap-7.1.0_1\jboss-eap-7.1\standalone\configuration\application.keystore not found, it will be auto generated on first use with a self signed certificate for host localhost

Warning related Keystore missing certificate

How ever first lets deploy the war file in to EAP and see whether its functioning. After starting the EAP go to JBoss Admin console  and navigate to Deployments tab. Then deploy your generated war file.

Now you should be able to access following URL
http://localhost:8080/RestApiSpringBoot-0.0.1-SNAPSHOT/findBook/1

And in browser you should be able to see similar output.

REST get API output

Lets generate the Key 

To generate the SSL key we are using Java "keytool". In order to generate the key open command prompt as Administrator and navigate Java installation directory. Then you can execute following command.

keytool.exe -genkey -alias server -keyalg RSA -keystore application.keystore -validity 2000


Once you enter above mentions command then first it will ask for the password I will use default password as "password". Then it will ask some basic details about your server you can provide your own details and will not have impact on these for now.

What is your first and last name?
Nirmal Balasooriya
What is the name of your organizational unit?
NimralBalasooriyaBlog
What is the name of your organization?
NirmalBalasooriyaBlog
What is the name of your City or Locality?
Singapore
What is the name of your State or Province?
Singapore
What is the two-letter country code for this unit?
SG
Is CN=Nirmal Balasooriya, OU=NimralBalasooriyaBlog, O=NirmalBalasooriyaBlog, L=Singapore, ST=Singapore, C=SG correct?
Yes

After these details it will ask you to enter password for another time for verification.

Generation of ssl key

Actually these details already configured in the standalone.xml in "<EAP_BASE_DIR>\standalone\configuration" directory. If you open the xml file and search for following "<security-realm name="ApplicationRealm">" in xml you can find these configurations as show below.


            <security-realm name="ApplicationRealm">
                <server-identities>
                    <ssl>
                        <keystore path="application.keystore" relative-to="jboss.server.config.dir" keystore-password="password" alias="server" key-password="password" generate-self-signed-certificate-host="localhost"/>
                    </ssl>
                </server-identities>
                <authentication>
                    <local default-user="$local" allowed-users="*" skip-group-loading="true"/>
                    <properties path="application-users.properties" relative-to="jboss.server.config.dir"/>
                </authentication>
                <authorization>
                    <properties path="application-roles.properties" relative-to="jboss.server.config.dir"/>
                </authorization>
            </security-realm>


So we are generated our ssl key based on this default configuration. Now you should be able to see new file "application.keystore" has been generated in Java bin folder. Then copy and past that file in to "<EAP_BASE_DIR>\standalone\configuration"



Lets test the application with SSL

After above modifications lets restart the JBoss EAP. Now you should be able to see similar out put as show in below.

Now you will not able to see previous warning that generated When EAP starts. Also you should able to see EAP is listening for HTTPS port as well.

INFO  [org.wildfly.extension.undertow] (MSC service thread 1-7) WFLYUT0006: Undertow HTTPS listener https listening on 127.0.0.1:8443

SSL is enable in EAP 7.1

Now if you try to access our web service with HTTPS following URL.

https://localhost:8443/RestApiSpringBoot-0.0.1-SNAPSHOT/findBook/1

Browser will give you warning that we are going to access "Your connection is not private" as show below.

Then click me Help me to understand and then Proceed to localhost (unsafe)

Then You should be able to see similar output as below.

Deploy static resource in war file using Maven

In this post I will demonstrate how we can deploy simple static file in a war file. This will only use maven and will not use any other framework.

Prerequisites 

1. You should have install java 1.8 or above.
2. You should have Eclipse/IntelliJ Idea installed in your PC.
3. Your PC should setup Maven installed and configured.

Create the Project

In InteliJIdea go to Files - > New -> Project select default JDK installed and click next as show in below figure.

Then provide Project name and GroupID to your project. I will use following details

Name      : StaticWebResource
GroupID : com.nirmal.blog

Then click Finish.


Add relevant dependencies Project

Lets add relevant dependencies in to the project. Just modify project pom file as show below.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.nirmal.blog</groupId>
    <artifactId>StaticWebResource</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.3</version>
                <configuration>

            </plugin>
        </plugins>
        <finalName>StaticWebResource</finalName>
    </build>

</project>

Make sure to add maven-war-plugin and set the configuration "failOnMissingWebXml"  value as false.



Add static resource in to Project

For the demonstration purposes I will use "jquery.min.js". First download this file in to local PC. Then create new folder call webapp. Then put your static resources in this folder. In my demonstration I will put downloaded jquery.min.js file.

Lets Create the war file

To create the war file just perform maven install (Just double click on install under lifecycle in Maven section ) and then you can see the generated war file inside target folder.

Deploy in to JBoss server

Log in to the JBoss web admin console and navigate to deployments tab. Then click on Add button and Then click Next. Select war file and again click next and Click Finish. Application will successfully deployed in to the JBoss server.

Now you should be able to access the deployed static resource from following URL.

http://localhost:8080/StaticWebResource/jquery.min.js

Loaded static resource file. 

You can find project source on following GIT resource.

Spring Boot LDAP Authentication using ApacheDS -Part 01 Setup ApacheDS

In This post I will demonstrate how to setup opensource directory server ApacheDS in Windows operating system. In next blog post I will demonstrate how to use this ApacheDS to authenticate Spring Boot web application.
ApacheDS is an extensible and embeddable directory server entirely written in Java, which has been certified LDAPv3 compatible by the Open Group. Besides LDAP it supports Kerberos 5 and the Change Password Protocol. It has been designed to introduce triggers, stored procedures, queues and views to the world of LDAP which has lacked these rich constructs.

Download and install ApacheDS through ApacheStudio

Lets download ApacheStudio which allow us to brows and setup LDAP users in ApacheDS. You can find downloadable instance from official web page. Then install the ApacheStudio in to your local PC.

ApacheDS requires at least:

1. Windows XP, Vista or 7.
2. a Java Runtime Environment 6 or later.

Lets open ApacheStudio and then Create server instance from ApacheStudio by right click on LDAP Servers section (As show in below figure) and click New->New Server.

Then give Server Name and click finish. Now we have created ApacheDS instance and then lets create our own partition.

First double click on the server instance we created and click on Partitions section. Then click on Add button as show in below figure.

Then Click on ID and provide partition id in the field. I  have provided ID as "NirmalBlog" then Suffix section you have to provide Domain Component (DC) in your ldap settings so I have provided it as "nirmalblog" and then save.

Then lets start the server by right click on server instance and start server.

Run server instance

Click on Connections section(As show in below figure) and click New Connection in order to create connection to  ApacheDS instance we create.

Then provide your connection name(your proffered name), as show in below. Make sure to change the port to 10389 which is default port for ApacheDS.
Connection Name : nirmalBlogConnection
Hostname: localhost
Port:10389

Then click next and select Authentication Type as No Authentication. Then click finish.

Then you should be able to see LDAP connection through the ApacheStudio(similar to figure below)

Lets Setup LDAP users in ApacheDS through ApacheStudio

First I will list down some of common words used in LDAP

DC - Domain Component
OC - Organization Unit
DN - Distinguished Name
CN  - Common Name
SN  - Name

First Lets add Organization unit in our LDAP server for that right click on newly added Partition (dc=nirmalblog,dc=com) and click New->New Entry

Add new Entry

Then select Create entry from scratch(as show in below figure) and then click next

Then type "organization"in Available object classes field and select organizationalUnit and click Add button. Then organizationalUnit  added in to Selected Object Classes section and then click Next.

Then select ou and give organization unit as "users". As show in below figure.

Then click next and Then click finish. After that you should be able to see similar structure to below figure in your LDAP tree.

Then lets add new person in to this organization unit. For that right click on "users" organization unit that we have added and right click then click New->New Entity.
Then select  "Create entry from scratch" and click Next.
Then type "inetOrgPerson"in Available object classes field and select inetOrgPerson and click Add button. Then inetOrgPerson added in to Selected Object Classes section and then click Next.

Then I will provide following details in to my user

cn - nirmal
sn - balasooriya
emplyeeNumber - 1
mail - nirmal@blog.com

Then click Next. On next page click on new Attribute button show in below figure.

Then type "userPassword" in Attribute type and click Finish.

Once you click Finish it will popup dialog box to enter new password for the user. Then type user password and reenter the password. Then click Ok.

After that you should able to see similar figure as below. Then Click Finish

Now new user should be added in to LDAP tree structure similar to below figure.

So we have setup our LDAP server with one user and on next Blog post I will demonstrate how to use this setup to authorization of users on Spring Boot web application .

Setup MICROSOFT SQL SERVER Data source in JBoss EAP 7.1

In this post I will demonstrate how to setup Microsoft SQL Server Data source in JBoss EAP 7.1. I will use code base of my previous post "Passing spring application parameters in EAP 7.1"(Initial code base)

Prerequisites 

1. You should have install java 1.8 or above.
2. You should have Eclipse installed in your PC.
3. Your PC should setup Maven installed and configured.
4. Your PC should have installed MySQL and Server need to have user who have access to the configured database and user should able to log in to the database by user name/password. 

Install MSSQL driver in JBoss EAP

First lets download a JDBC Driver based on SQLServer version. You can download the JDBC Driver from Microsoft's site: https://docs.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server

I downloaded the "sqljdbc4-2.0.jar" which compatible with my SQL server version. Lets keep the downloaded jar in temporary folder. In my case I'll keep it on "G:/" drive. 

So lets use "JBoss-cli" in order to add the Driver and JNDI in to EAP. You can find the jboss-cli in <JBOSS_HOM>/bin directory.

You can start the EAP first by double click on standalone.bat and then start jboss-cli by double click jboss-cli.jar.

Then you can enter connect command in order to connect to EAP.

connect

Then you can enter following command

module add --name=sqlserver.jdbc --resources=@INSTALL_FOLDER@/libext/jtds-1.3.1.jar --dependencies=javax.api,javax.transaction.api
/subsystem=datasources/jdbc-driver=sqlserver:add(driver-module-name=sqlserver.jdbc,driver-name=sqlserver,driver-class-name=@JDBC_DRIVER@)
/subsystem=datasources/data-source=@DATASOURCENAME@:add(jndi-name=java:jboss/@JNDI_NAME@,enabled="true",use-java-context="true",driver-name=sqlserver,connection-url="@JDBC_URL@",user-name=@JDBC_USER@,password=@JDBC_PASSWORD@,validate-on-match=true,background-validation=true)

This is stranded command which you can replace with your parameters. So based on my parameter details Command would be something like below. I have highlighted the modifications which I have done.


module add --name=sqlserver.jdbc --resources=G:\sqljdbc4-2.0.jar --dependencies=javax.api,javax.transaction.api
/subsystem=datasources/jdbc-driver=sqlserver:add(driver-module-name=sqlserver.jdbc,driver-name=sqlserver,driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver)
/subsystem=datasources/data-source=MSSQLDATASOURCE:add(jndi-name=java:jboss/MSSQLJNDI,enabled="true",use-java-context="true",driver-name=sqlserver,connection-url="jdbc:sqlserver://localhost;databaseName=TestDB",user-name=nirmal,password=Test123_,validate-on-match=true,background-validation=true)

Once you run the command you should be able to see following output in jboss-cli.

Then also you can see following section has been added in to the standalone.xml

Lets configure Application to read JNDI

In order to read the DataSource details from JNDI just need to add JNDI string in to Spring Boot application.properties file. I have added spring.datasource.jndi-name=java:jboss/MSSQLJNDI@ application.properties file. (Note that I have commented previous datasource configuration details )

#==== connect to MSSQL ======#
#spring.jpa.hibernate.ddl-auto=update
#spring.datasource.url=jdbc:sqlserver://localhost;databaseName=TestDB
##spring.datasource.username=nirmal
##spring.datasource.password=Test123_
#spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
#spring.jpa.database-platform=org.hibernate.dialect.SQLServer2012Dialect
server.port = 8080
spring.datasource.jndi-name=java:jboss/MSSQLJNDI@

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=false
spring.jpa.properties.hibernate.format_sql=true

#==== Logging configurations ======#
logging.level.root=WARN,INFO,ERROR
logging.level.com.baeldung=TRACE

Then lets deploy the war file. For that click on Back button on left top corner and then click on deployments. Then click "Add" button. Then you should be able to see similar figure to below.

Then click next button and then Click choose file and select the generated war file from target folder in the project. Then click next and then click finish. Once installation completed you should be able to see similar output on command line.

http://localhost:8080/RestApiSpringBoot-0.0.1-SNAPSHOT/findBook/1

Also you can perform any action which I mentioned in my previous blog post.

Project source can be downloaded from following GIT HUB URL.

Managing resources using Jackrabbit with Spring Boot

In this post I will demonstrate how to work with Jackrabbit content repository with Spring Boot application. The Apache Jackrabbit content repository is a fully conforming implementation of the Content Repository for Java Technology API. A content repository is a hierarchical content store with support for structured and unstructured content, full text search, versioning, transactions, observation etc.

Prerequisites 

1. You should have install java 1.8 or above.
2. You should have Eclipse/IntelliJ Idea installed in your PC.
3. Your PC should setup Maven installed and configured.

Lets setup Jackrabbit 

You can download the latest jackrabbit from official Jackrabbit web page . I will download the war file and deploy it on JBoss EAP.

To deploy it in to JBoss EAP you should have access the web admin console. In there  go to Deployments and click "Add" button show in figure below. Then click next and select the war file you downloaded. Then click next and then click finish.

Once you successfully installed the application you should be able to access the default jackrabit web interface from http://localhost:8080/jackrabbit-webapp-2.18.5/ you should see similar page as show below.

Create your first repository by click on "Create Content Repository". By click on this button system will create the default Jackrabbit repository with default settings.

Success Page of JackRabbit repository creation 

Now when you access Jackrabbit default URL you will be able to see as follows.

When you create this repository JBoss EAP will create new folder call "jackrabbit" on <JBOSS_HOME_DIR>/bin folder. As show in below.

Lets create project 

Open InelliJ IDEA and create new maven project. I will using following details for the project.

groupId    : com.nirmal.JackrabbitSpringBoot

artifactId : JackrabbitSpringBoot

I will add relevant dependencies in to the POM file as show below.

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>

        </plugins>

    </build>

</project>

Then I will add application.properties file in resources folder with following content. note that I will use default jackrabit user name and password in this demonstration. Jackrabit url can be get as following format http://<ip address>:<port>/<contextpathOfJackrabitserver>/server

#==== connect to mssql ======#

spring.jpa.hibernate.ddl-auto=update

spring.datasource.url=jdbc:sqlserver://localhost;databaseName=TestDB

spring.datasource.username=nirmal

spring.datasource.password=Test123_

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver

spring.jpa.database-platform=org.hibernate.dialect.SQLServer2012Dialect

server.port = 9090

spring.jpa.properties.hibernate.show_sql=true

spring.jpa.properties.hibernate.use_sql_comments=false

spring.jpa.properties.hibernate.format_sql=true

#jackrabbit configs

jackrabbit.username=admin

jackrabbit.userpassword=admin

jackrabbit.url=http://localhost:8080/jackrabbit-webapp-2.18.5/server

Then I will add spring boot startup class as  AppInitializer class with following content in "com.nirmal.JackrabbitSpringBoot.app" package.

package com.nirmal.JackrabbitSpringBoot.app;

    import javax.sql.DataSource;

    import org.springframework.beans.factory.annotation.Autowired;

    import org.springframework.boot.SpringApplication;

    import org.springframework.boot.autoconfigure.SpringBootApplication;

    import org.springframework.boot.builder.SpringApplicationBuilder;

    import org.springframework.boot.web.support.SpringBootServletInitializer;

    import org.springframework.context.annotation.ComponentScan;

/**

 * Spring Boot initialization class of the JackrabbitSpringBoot project

 *

 * @author Nirmal Balasooriya

 *

 */

//@EnableJpaRepositories("com.nirmal.springbootrest")

@SpringBootApplication(scanBasePackages = { "com.nirmal.JackrabbitSpringBoot.app" })

@ComponentScan({"com.nirmal.JackrabbitSpringBoot.app"})

public class AppInitializer extends SpringBootServletInitializer {

    @Autowired

    DataSource dataSource;

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(AppInitializer.class);

    }

    public static void main(String[] args) {

        SpringApplication.run(AppInitializer.class, args);

    }

}

Next Lets add the Controller. In my controller it will have two API methods call "getImage" and "uploadResource". Both will take both will take path variable call "resourceName". (This is image name without extension). Full controller will be as below.

package com.nirmal.JackrabbitSpringBoot.app;

import org.apache.tika.io.IOUtils;

        JackRabitResource jackRabitResource=new JackRabitResource();

        resourceName=resourceName+".jpg";

        Response<JackRabitResource> response = new Response<JackRabitResource>("0", "Resource does not exist", null);

        if (new ClassPathResource(resourceName).exists()){

            uploadFile(resourceName);

            response = new Response<JackRabitResource>("1", "Resource Added Successfully", jackRabitResource);

        }

        return response;

    }

    @GetMapping(

            value = "/getImage/{resourceName}",

            produces = MediaType.IMAGE_JPEG_VALUE

    )

    public @ResponseBody byte[] getImage(@PathVariable("resourceName")String resourceName) throws Exception {

        logger.info("Get Image resourceName : " + resourceName);

        resourceName=resourceName+".jpg";

        if (new ClassPathResource(resourceName).exists()){

            try {

                return getContent(resourceName);

            }catch (PathNotFoundException e){

                return null;

            }

        }

        return null;

    }

    public void uploadFile(String name) throws Exception{

        Repository repository = JcrUtils.getRepository(jackrabbitUrl);

        Session session = repository.login(

                new SimpleCredentials(username, userPassword.toCharArray()));

        try{

            Resource resource = new ClassPathResource(name);

            InputStream stream = resource.getInputStream();

            Node folder = session.getRootNode();

            Node file = folder.addNode(name,"nt:file");

            Node content = file.addNode("jcr:content","nt:resource");

            Binary binary = session.getValueFactory().createBinary(stream);

            content.setProperty("jcr:data",binary);

            content.setProperty("jcr:mimeType","image/gif");

            session.save();

        }finally{

            session.logout();

        }

    }

    public byte[] getContent(String name) throws Exception{

        Repository repository = JcrUtils.getRepository(jackrabbitUrl);

        Session session = repository.login(

                new SimpleCredentials(username, userPassword.toCharArray()));

        Node folder = session.getRootNode();

        Node file=folder.getNode(name);

        Node content=file.getNode("jcr:content");

        String path = content.getPath();

        Binary bin = session.getNode(path).getProperty("jcr:data").getBinary();

        InputStream stream = bin.getStream();

        return IOUtils.toByteArray(stream);

For testing purposes I will put two jpg images in resource folder so after all there you could see similar project structure as below figure.

Final project structure 

Lets run the applciation

You can perform maven install command on the project and then you can run the application by following command in target folder. Make sure that JBoss EAP which we deployed jackrabbit server running while you are testing.

java -jar JackrabbitSpringBoot-1.0-SNAPSHOT.jar

Once application successfully started you could see similar console output as show below.

Also you should be able to access following URL from browser http://localhost:9090/getImage/srilanka and should get following output on web browser.

Then lets try to upload two images in to jackrabbit repository which I added in side the resource folder. You can brows following URL and should able to get respective outputs as well.

http://localhost:9090/uploadResource/colombo

http://localhost:9090/uploadResource/srilanka

Since both resources "srilanka.jpg" and "colombo.jpg" available in resources folder both occasions it will return following output.

{"code":"1","desc":"Resource Added Successfully","t":null}

In case if you try to access not available resource as below.

http://localhost:9090/uploadResource/corona

{"code":"0","desc":"Resource does not exist","t":null}

So now we can access our jackrabit repository from following URL and see whether resources are uploaded.

http://localhost:8080/jackrabbit-webapp-2.18.5/repository/default/

You should be able to see as following 

Then lets try to access resources in Jackrabbit repository. for respective URLs should return similar output as show below.

http://localhost:9090/getImage/srilanka

Retrieving image from repository

http://localhost:9090/getImage/colombo

Retrieving image from repository

You can find the code base related to this project from following FITHUB location.
