ActionMappings ClassCastException keeps reocurring
The following error keeps occurring when I try to use a basic login.jsp
page that I've copied from the struts example in the binary
distribution. If I restart tomcat (3.2), this goes away for awhile, but
eventually starts happening again and I have to restart tomcat again to
get things to work. The struts-example web app runs fine, so I'm sure
I've done something wrong, but I cannot figure out what! Can anyone
help me figure out what could cause this?

Re: ActionMappings ClassCastException keeps reocurring
Posted by "Craig R. McClanahan" <cr...@apache.org>.
You probably have a copy of struts.jar visible on the classpath (or in
$JAVA_HOME/jre/lib/ext) as well as in your webapp. Struts 1.0.x does not
support this configuration -- struts.jar belongs inside your webapp only.
Struts 1.1 is designed to support this, but it hasn't been thoroughly
debugged.
