Struts Example Help.

[Sumanth Tarigopula]

I followed the instructions for installing the struts example in Web Logic6.1. I keep getting a ClassNotFoundException error looking up "org.apache.struts.webapp.example.DatabaseServlet". I copied the struts-example.war into the applications/DefaultWebApp and still keep getting the error. DatabaseServlet.class is a part of the struts-example.war and is in applications/DefaultWebApp directory.
Any help is appreciated.
Thanks

[David Meyers]

Try adding the struts jar to your weblogic classpath

[Thomas Paul]

I don't think that is the problem because you would get a Struts error. This sounds like a WebLogic deployment problem. Why not ask in the WebLogic forum?

[Stelian Iancu]

I had the exact same problem with Tomcat 4.0.1. It happened because I didn't restart Tomcat after putting the examples into webapps. After I restarted it, it worked.
