When I was doing Struts today, I had a problem - after setting the actionform to struts-config.xml, how DEPLOY can't. After more than 3 hours of inspection, I found that I am a mistake I committed, I put an actionform in the path of the same name in the ClassPath in WebLogic Server. When loading ACTIONFORM, VM first looks in the classpath in the WebLogic environment, and finds the package, but can't find the corresponding Class in the package, so the load is not available. The above is just my idea, the specific is the case, but also to verify it. Now I have changed a path, you can.
