Well, naturally upgrading WLS should hav no effect on the Eclipse installation. If you’re running Eclipse 3.0, I’d suggest deleting the <eclipse-install>/configuration directory and restarting Eclipse. If that doesn’t correct the problem can you please post all the information we request in the [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL] thread at the top of this forum? That will give us some context so that we can determine if this is an installation issue, a configuration problem, or a bug. Thanks.
