I am working on my first EGL app. I exported it from WDSc (http://archive.midrange.com/wdsci-l/200803/msg00017.html) and deployed it to a WebSphere Application Server Express server. My application is giving me the following:
Error 500: java.lang.LinkageError: LinkageError while defining class: jsfhandlers.Master Could not be defined due to: jsfhandlers/Master This is often caused by having a class defined at multiple locations within the classloader hierarchy. Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature.
