Instead of copying myapp.war file to the deploy directory, create a myapp.war directory, place the war file contents (index.jsp, WEB-INF/web.xml, etc.) into that directory, and move that directory to the deploy directory.
Then, when you have new video content, copy it to the appropriate location, such as myapp.war/video.
Don't know how to do this using the JBuilder, I use Ant to build and deploy.
Thanks it worked fine.
I am really grateful
