Swing Library

Create a jython virtual environment…

git clone git://github.com/robotframework/RemoteApplications.git
cd RemoteApplications
jython build.py package
cp target/remoteapplications-1.3-jar-with-dependencies.jar demo/lib/
cd demo
jython run.py robot-tests/javaws_application.txt

If you change the URL to a valid WebStart application, then I managed to find the page components using the following commands in javaws_application.txt:
