java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester Apache 7

Question

Hi i am trying to use following technologies together :

• MyFaces 2.1.12
• jstl 1.2
• Apache 7

but when trying to run my application, i got the following exception:

java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester

Caused by: java.lang.ClassNotFoundException: org.apache.commons.digester.Digester

Wich is very disturbing, because I have linked the commons-digester3-3.2.jar in my project, put it in the lib directory under "Web-INF" and added it in the java build path...what's wrong?

Thanks,

Use commons-digester version 1.8 . commons-digester3 has a lot of changes already.
