This looks like a classic BEA Classloading issue. Check this article to get
an understanding of how to resolve this.
http://www.onjava.com/pub/a/onjava/2001/06/26/ejb.html
The article is a bit more general than this specific problem, but it describes the
solution you need. It's written by someone from BEA.1
You'll need to identify the jar files required to be on the classpath in the Manifest
of the ear file using a "classpath:" line.
I've got struts running on BEA weblogic 6.1 sp3 right now...
Best of luck,
Kevin

Subject: Struts 1.1 beta2 on Weblogic 6.1 SP3 deployment problem
Hi people,
I'm a newbie in the mailing list.
My environment is Weblogic 6.1 SP3 (Win 2000) running Struts 1.1 Beta 2.
With Struts alone via war deployment itself...it works great with this
message: -

I've scan through the forum, and it seems some say that weblogic has got
some special class loader problem. Others say it's fix by adding a
classpath to the manifest file like this: -
Manifest-Version: 1.0
Created-By: Apache Ant 1.5
Class-Path: commons-beanutils.jar commons-collections.jar
Class-Path: commons-dbcp.jar commons-digester.jar
Class-Path: commons-logging.jar commons-pool.jar
Class-Path: commons-services.jar commons-validator.jar
Class-Path: jakarta-oro.jar struts.jar
No, my Weblogic classpath hasn't got Struts.jar on it.
Anyone has got any other suggestion, please?
Regards,
Tzer
