Remember that the original error is that the Linux SWT library isn't found. I'd expect the null set above.
It seems that GWT 1.6 is there by virtue of Genuitec's MyEclipse. It also seems that you have the GEP. Please search for "gwt-user.jar" The search above only looked for Eclipse-specific stuff. It's possible that there's another GWT 1.6 installation lurking. At this point I'm torn between removing MyEclipse or removing just the GWT and GEP. Do you understand enough about Eclipse to install/remove plugins? If not, I'd nuke MyEclipse. My advice is to get to a working GWT 1.6 that's independent of MyEclipse. See http://code.google.com/webtoolkit/versions.html You don't need MyEclipse's bundled version of GWT that comes with the GEP. Once you've verified that there are no other unexpected GWT installations, and either installed a standalone version of GWT1.6 or verified that MyEclipse is correct and complete, prove the installation by building the samples, I want to see a successful build of the samples. This will bolster your confidence and prepare you for the MyEclipse/Instantions debugging. I know this bites the big one, but there's too much stuff all at once. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
