Upload Large Files in JBoss EAP - Resolve UT000020: Connection terminated as request was larger than 10485760

In this post I will demonstrate how to resolve "UT000020: Connection terminated as request was larger than 10485760". This error because of the file that we going to upload exceeds maximum size allowed in default configuration (10MB) on JBoss EAP. For demonstration purposes I will use JackRabbit post code.

For the testing purposes I have added new Image (LARGE.JPG) in to resource folder and if you try to execute following command in browser you will hit an error.

http://localhost:9090/uploadResource/large

Exception in the Spring-Boot application

Also if you check in JBoss log you should be see following exception.

Exception in JBoss EAP

The main reason for this exception is we are trying to upload a file which size is larger than the default allowed size in JBoss.

Lets see how we can configure to allow JBoss to configure it for 100MB file.
First You have to log in to JBoss EAP admin console(http://127.0.0.1:9990/console/App.html#home) using username and password.

Then navigate to Configuration page and then click on "SubSystems" in left panel then click on "Web/HTTP - Undertow". Then Click on  view button on "HTTP". Please refer to below image.

Then you should able to view similar page to below figure. Then click on "HTTP SERVER" Tab and click on View button as show in below figure.

Then click on "HTTP Listener" in right side panel and then click on Edit button as show in below figure.

Then find the parameter name "Max post size" and set value as "104857600" (this is in byte value) which equal to 100 MB. Then Click save button and re-lode the server.

After that change if you try to upload large file by following URL it will get sucess.

http://localhost:9090/uploadResource/large

You could see following output on web browser.

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


also if you try to access that image using following URL you should be able to see uploaded image.

http://localhost:9090/getImage/large

Code base for this can be found in following GITHUB location.
