Apparently there is a problem with Servlet Name 'Action' from org.apache.struts.action.ActionServlet. Unfurtunatley I don't know what am I doing wrong. Have you an idea? Many thx in advance. Olli

Answer 1

This error occurred because your servlet-core jar is not on your run-time class-path. If you are using maven,

1. Open your EAR/web project properties
2. Click on "Deployment Assembly"
3. Click on "Add..."
4. Select on "Java Build Path Entries"
5. Click on "Next"
6. Select "Maven Dependencies"
7. Click "Finish"

If not maven, make sure you have the lib folder where your jars are placed is on "Deployment Assembly".
