struts plug-in for struts-menu causing action not to preload

[dawnsk1]

Hi all,

I'm hoping that this is the correct forum and someone can help me out
with a problem that has been driving me nutty lately. I'm working
with struts-menu-2.3 and I'm seeing an exception every time I include
the plug-in definition in my struts-config.xml.

Per the struts-menu website, I have included these lines in my
struts-config:
------------------------------------------------------------------
<plug-in className="net.sf.navigator.menu.MenuPlugIn">
<set-property property="menuConfig"
value="/WEB-INF/menu-config.xml"/>
</plug-in>
------------------------------------------------------------------

When I bring up my application server, I see an exception when this
plug-in is trying to be referenced:
------------------------------------------------------------------
[java] <Feb 14, 2005 9:23:47 AM EST> <Error> <HTTP> <BEA-101216>
<Servlet: "action" failed to preload on startup in Web application:
"cst".

My environment is struts-1.2.4 and weblogic-8.1-sp2.

I'm at my wits end trying to figure out why this is happening. At
one time I thought that the jar I downloaded was corrupt, but I have
tried multiple mirrors, versions, and packagings (war and jar) and
still see the same exception.

If anyone has any suggestions at all, regardless if you might think it
is only a minor suggestion, I would greatly greatly greatly appreciate
hearing from you.

Thank you all very much,
-Dawn
