When you download "raw" 1.6 or 1.5, they have nothing to do with eclipse. So, I'm somewhat confused, and we may be getting closer to resolving the problem. Did you download those files from http://code.google.com/webtoolkit/versions.html? If not, please remove/rename (see the note below) in the eclipse directory. Then install GWT 1.5 from the webtoolkit site. This should put GWT 1.5 into some directory like "/usr/local/lib" (or however you manage your system). It should have absolutely nothing to do with eclipse. You can tell instantiations to refer to a non-eclipse path for the GWT library location. I don't know instantiations. If it provides a work-alike for GEP, remove GEP (since we prefer instatiations over GEP if instantiations is a super-set of GEP). To use instantiations, you should remove all traces of GWT 1.6. I say this knowing full well that it's possible to point instantiations at GWT1.5. However, to get things up-and-running, you should start with a clean slate, in an environment that will move you to using instantiations with as few distractions as possible. > > I removed the plugin but that apparently does not result in actually > deleting the files.

I think some of it depends on how you installed eclipse, and since you're on OSX, that's unfamiliar territory for me. On my box, I upgrade/install as root, and work in eclipse in a regular user account. I also know that eclipse records information in a user-private directory. All that being said: when I encounter problems like this (esp. w/ eclipse which is such a pita to configure) I rename the offending directory. This rename effectively deletes the file, but leaves it available to recover when eclipse goes belly-up. E.g. rename it to "com.google.gwt.eclipse.sdkbundle.macosx_1.6.4.v200904062334.delete.me" I still think that because of the reliance on instantions, you should forget about GWT 1.6 for now. See the above comment. Concentrate on getting a successful build of the 1.5 samples in a pristine environment. Leaving 1.6 out there means an additional step of verifying that installation. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
