Exception starting filter struts2 java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter [duplicate]

Answer 1

I had the same problem. I was able to solve it by adding a few more jar files. You must have at least the following jar files:

1. commons-fileupload-X.X.X.jar
2. commons-io-X.X.jar
3. commons-lang-X.X.jar
4. commons-logging-X.X.X.jar
5. commons-logging-api-X.X.jar
6. commons-lang3-X.X.jar
7. freemaker-X.X.X.jar
8. javassist-X.X.X.GA.jar
9. ognl-X.X.X.jar
10. struts2-core-X.X.X.X.jar
11. xwork-core-X.X.X.X.jar
