Issue: Precompiling with Struts-EL for Weblogic

Edit 10/13/2005: Apparently BEA has a workaround, and it is fixed in Service Pack 4!


For some reason the wlappc task of weblogic blows up when trying to precompile an war that uses the Struts-EL jar. This works fine with only the struts.jar so something is up with the struts-el.jar. Has anyone else seen this problem?

I've found a post about this in the BEA dev2dev Forums. As well as a post on the struts mailing list. So it would appear that this is a global issue between the struts-el.jar and the wlappc weblogic precompiling ant task.

Here is the exception that is received, that seems to point to a MessageResources issue:
