Hi,
if I deploy my EJB-applikation using struts (struts.jar is stored in the
.war-file in WEB-INF/lib) as .ear-file (on WLS6.0 SP1 running on NT4.0 or
Win2000) I get exceptions like:
java.lang.NoClassDefFoundError: org/apache/struts/action/ActionForm

(The classloader seems to find the ActionServlet but not the ActionForm)
I read all posting concerning "classloader" here and in the WL-news-groups
and tried some sugestions (including placing struts.jar in the CLASSPATH in
startWeblogic-script and removing    <load-on-startup>1</load-on-startup>
from web.xml ) but nothing helps. 

If  I expand the .war-file by myself to appropriate directory structure all
works perfectly well.

Thanks,
  Damian
