WebSphere 8.0.0.3上的MyFaces 2.1.8项目

Question

I need to run my Java EE 6 project on WebSphere Application Server 8.0.0.3. The Server has Apache MyFaces 2.0 Support.

When I use the Server lib, the deployment works, but my application has some bugs. Therefore I use Apache MyFaces 2.1.8. I put the api and impl in my WEB-INF/lib/ dir. Also I configured my WAS parent_last and jsf-implementation SUNRI1.2.

When I deploy my project I get the following Exception:

[9/5/12 8:18:57:823 CEST] 00000009 StartupServle I   MyFaces already initialized

My faces-config is empty.

What can I do to fix this issue?

Answer 1

Setting the WarClassloader parent last fixed the problem. Another way is shared lib.
