Can I make a change in propietary war file?

Question

Hi I have a proprietary application and its war file is available to us. I need to basically add a jsp page to the current application. I was thinking i will write the independent jsp, java files build a war and add it to the proprietary war file.

Or

i will write the jsp, java files and add it to the same war.

Can i make a new war and make the proprietory to interact.. Which option is better.

Answer 1

I think you could unpack the war, then add your jsp. After that, re-build the war file.

Answer 2

Yes. Just unpack the war and add your custom content. Your libraries go in WEB-INF/lib and your classes in WEB-INF/classes. You can also add servlets, filters, and listeners to web.xml as needed.
