java.lang.NoClassDefFoundError: org/apache/struts/action/ActionForm
Hi I am working on a project and we are building an ear file that cosists of
2 jars and a war file. When deploying it on the Weblogic Server it reports
no errors, but when requesting the url from the browser it reports the
follwing error:
java.lang.NoClassDefFoundError: org/apache/struts/action/ActionForm

............................................
I am sure I have the struts.jar in my WEB-INF/lib directory which is
located in the war file and I don't now what is going on. Any
suggestions would be appreciated.

I agree with Laurie below that (b) is probably the culprit, except I know
I have read (on struts.apache.org) that the only place your struts.jar
ought to be is in WEB-INF/lib of your web application. If for example
other copies are present elsewhere (other than in a web application
context) I think they should be removed.. However, I have only worked with
Tomcat so maybe WLS does things differently..(though I would be surprised
if that were so...- my 2 bits..:))

I haven't used WLS much, but this is almost certainly either (a) you don't
have the Struts jars in place as you think you do ;-) or (b) there are
copies elsewhere on WLS's classpath. Does it have a copy of Struts bundled
or something? Try removing struts.jar from WEB-INF/lib. If that changes
the
behaviour, you probably have situation (b).
