Problems with running struts example under Tomcat

When I try the just dropping struts-example.was un the webapps dir of
Tomcat and then restarting the server, I get the following ClassNotFound
exception. I can always force the server to see the application classes
by adding the dir to the CLASSPATH, but shouldn't the install
instructions for struts-example just have worked? Is there some nuance
of deploying .war s that I'm missing here? Thanks

Hmm, your Hotspot thinks it is 1.2.1.  Would it be possible to update to the most recent
1.2.2 patch release (I think it is 1.2.2_05) from JavaSoft's web site?

Yes, they should have worked.  In fact, they work for me in the following environments:
* Linux, IBM JDK 1.1.8, Tomcat 3.1 final
* Linux, IBM JDK 1.1.8, Tomcat 3.2 beta
* Linux, Sun JDK 1.2.2, Tomcat 3.1 final
* Linux, Sun JDK 1.2.2, Tomcat 3.2 beta
* Windows98, Sun JDK 1.2.2, Tomcat 3.1 final
* Windows98, Sun JDK 1.2.2, Tomcat 3.2 beta
* Windows98, Sun 1.3.0, Tomcat 3.1 final
* Windows98, Sun 1.3.0, Tomcat 3.2 beta

I've heard other reports of using Struts successfully with Tomcat on many platforms.  What
JDK are you using?.  (In particular, I'm normally building and testing with JDKs that return
the following for "java -version"):

    Classic VM (build 1.2.2-L, green threads, javacomp)

    Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)
