    Hmmm, I had some problems with my mails yesterday, I don't know if my
    send worked, so I send it again, sorry if you have already received it.

    Hi all,

    I have freshly installed Eclipse 3.5.0 with WOLips stable build
    3.4.5924 (from the update site) and I can't get my WO-apps to start.
    Every timeI launch a WOApp, I get the following error:

    java.lang.NullPointerException
        at
    org.objectstyle.wolips.jdt.classpath.model.EclipseDependency.getSystemRoot(EclipseDependency.java:63)

        at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

    My environment variables NEXT_ROOT and NEXT_SYSTEM_ROOT are set.

    I have tried to delete my launch config and recreate it without any
    change. I've also tried to create a new empty WOProject, and the same
    error occurred.
    This is also happening with the today wolips nightly build.

    If I use the wolips version 3.3.5640, my wo application can start but
    the WOD/Html view is not working anymore (which seems to be normal with
    this eclipse version).

    My configuration:
    Eclipse 3.5.0 - WOLips/M2Eclipse
    JDK 1.6 update 16 (64 bits)
    OS: Win VISTA 64 bits Ultimate

    Any ideas?

    Thanks,
    Nicolas
