Re: java.lang.NoClassDefFoundError

[Jon Wingfield]

Looks like you've using OpenEJB ;)
The OpenEJB distro comes with a war file,  which looks like it's been 
expanded to a context by your tomcat install. However, the war file 
doesn't contain the required OpenEJB jar files (which probably need to 
be put in common/lib or server/lib).
The class file for org/openejb/OpenEJB is in the openejb-0.9.1.jar.
Deploy that and you should be set (well, this error will go away, at 
least) .

HTH,

Jon

Tomcat List,
               This might not be a Tomcat problem but I imagine that
you might be able to help anyways.  Every time I start Tomcat, I get
this error:

I know that Tomcat doesn't use the CLASSPATH but it appears that the
error is because a class can't be found.  Can someone help me resolve
this?  Thanks,
