WebSphere 5.1.1.5 and jsp2.0.jar

[Farrar Brian John \(USI\)]

I am using MyFaces with Websphere 5.1.1.5. Obviously, this is a pre 5.2 release and I believe that it uses the JSP 1.2 specification.   Using the “normal” classloader mode which is PARENT_FIRST (I’m not sure if the other app servers use this same terminology, it indicates that the classloader precedence is application server on down) everything works fine. I am including both jsp2.0.jar and commons-el.jar in WEB-INF/lib of the web module.   Unfortunately, the classloader mode of the production environment which I must deploy into is PARENT_LAST Iindicating that the classloader precedence begins with the web module). Under this classloader mode, all of the non-faces jsp’s don’t work, I’m not absolutely certain as to the cause but I think it is because they find the jsp2.0.jar before the application server’s jsp  1.2 library.   Does anyone have any suggestions or workaround? (other than change the classloader mode ;-) Does MyFaces need the entire jsp2.0.jar or only part of it?
