Thanks Abdullah, I got that working. The tutorial<http://code.google.com/webtoolkit/doc/latest/tutorial/appengine.html> tells to download stockwacher projec<http://code.google.com/webtoolkit/doc/latest/tutorial/projects/GettingStartedAppEngine.zip>t and import it in eclipse. The package contains old gwt-rpc.jar which is not compatible with new gwt sdk and hence fails with exception I pasted in my earlier mail. A easy fix is to build new project and copy jar from new project to stockwatcher one.
