Web Server 6.1 and too large war files.

We found out that the Sun Java Enterprise System WebServer 6.1 has a upload limit of 10 MByte for web applications. Apparently we were very close to that limit for some time without knowing about it. But when you add a WebService or EJB client to a Creator application, all the support jar files will bring the size over that limit.

The solution is to reconfigure the WebServer’s admin application to allow bigger uploads. Simply do the following when you see the problem:

• Stop the WebServer admin server.

• Back the <WS_HOME>/bin/https/webapps/admin-app/WEB-INF/web.xml up!

• Add the following init-param to the webappdeploy servlet.

  $ diff -uwb web.xml.orig web.xml

• Start the WebServer admin server and all the target servers.

Thanks to M. Kapur for this information.

I hope this helps a couple of people.
