Struts.jar in Weblogic5.1 SP8 Classpath?

[Ana Narvaez Vila <an...@sema.es>]

I have struts.jar in directory 'lib' of my webapp, sometimes I receive
'NoClassDefFoundError' althought everything seems to work ok.

If I append struts.jar to my WEBLOGICCLASSPATH, that exception is not
thrown.

Anyone knows something about that?

you're probably running into those Weblogic classloader
problems. Turning on JSP precompilation and switching off
servlet and JSP reloading in the web.xml deployment descriptor
should help.
