    Here is the copy of the e-mail that I sent originally. I have also
    included the files. They are not submitted as a patch file, I had to
    pretty much totally re-write both classes. The answer to your question
    is Yes, I have a framework in my /Library/Frameworks
    (C:\Apple\Local\Library\Frameworks on windows XP) and as a eclipse
    project, that way I don't have to build and install the framework after
    each time I change it. I normally set up my business logic in it's own
    frameworks, and I have some shared frameworks that I use on multiple
    projects.
     
    Thanks

    I have attached two files for updating the RuntimeClassProvider for
    launching WOApps. The problem with the current launcher is that if you
    have included multiple frameworks from other eclipse projects, is that
    it will include some of the same jars multiple times. Then when it
    would go through and start initializing the frameworks, and throw an
    error complaining about a duplicate framework.
     
    For Example:
     
    Application A - references FrameworksB, FrameworksC & FrameworksD (as
    eclipse projects)
     
    FrameworksB - references FrameworksC
     
    FrameworksC - references FrameworksD
     
    FrameworksD
     
    When generating the classpath for application A it would generate
    something similar to this.

    I have been using the code for a couple of months now, it has been
    stable.

    Can you resubmit to the mailing list? That's probably the easiest way
    -- That way whoever gets to it first can integrate the patch. So what's
    the exact scenario here? You have a framework that is in
    /Library/Frameworks and ALSO is the source to it as a referenced project
    that is actually in Eclipse too?

            It appears that this problem is occurring when you have a
    framework that is listed in both Projects and in the WOFrameworks
    classpath container. It is including one of them twice. When in
    actuality it should use the one from the project first. Because, I am
    working under the assumption that I might be changing and debugging the
    framework and want to use the integrated debugger to do so.

            Perhaps I am wrong about that, if there is a better way please
    advise me as to what it is. I am willing to send the code again, but I
    am not sure who is actually running this project to get it included in
    as a fix.
