Re: RE: DWR 2.0.x and WebSphere 6.0

Hi Joe,Just wanted to know if we have the fix for this issue in CVS. I tried getting latest from CVS and building dwr.jar with jdk1.3 and jdk1.5, but its not working on Webshpere 6. and giving same errors as in the first case.Thanks and regards,Sandesh0000002c ServletWrappe E   SRVE0100E: Did not realize  init() exception thrown by servlet dwr-invoker: java.lang.LinkageError: LinkageError while defining class: org.directwebremoting.annotations.AnnotationsConfiguratorCould not be defined due to: org/directwebremoting/annotations/AnnotationsConfigurator (Unsupported major.minor version 49.0)This is often caused by having a class defined at multiplelocations within the classloader hierarchy.  Other potential causesinclude compiling against an older or newer version of the classthat has an incompatible method signature.
