QWS is the Qt/embedded windowing server. You need to have it running or
have a launcher app that acts as a server. See the thread at
http://lists.trolltech.com/qt-embedded-interest/2001-10/msg00113.html
for example.

>From FAQ.awt:

   * Linker complains about missing symbols

    That could be an instance of moc trouble above, but more often
    it's a problem between C++ ABIs of the compiler used to build qt
    you want to link against, and the compiler you used to build
    kaffe's Qt-based AWT with.

    The GNU C++ compiler g++ had a short period where the ABI changed
    with almost every release, so if you are using a Qt library
    compiled with one of those 'interim' versions, your best bet is to
    rebuild Qt frim scratch with your current compiler.

  * QTDIR, QTEDIR, QPEDIR is pointing to the wrong directory.

    Qt uses QTDIR to find its fonts, and may use the other environment
    variables to locate other crucial bits for execution. Make sure
    that you've got them pointing to the right directories, i.e. the
    versions you compiled against. Read Qt toolkits installation
    description for more information on those environment variables.

You can use nm to figure out if Java_java_awt_Toolkit_tlkInit is really
in your libawt.
