    I tried to run JRebel with wicket application on Google App Engine. I have created simple wicket app with "wicket-archetype-quickstart" maven archetype and it worked with JRebel (on Tomcat). After few modifications I was able to run it on Google App Engine. Problem occured when I added JRebel support. Any attempt to load a page ends with an error:

    HTTP ERROR: 500

    access denied (java.io.FilePermission /home/marek/myworkspace/wicket_gae_test/src/main/resources/org/apache/wicket/RequestContext.class read)

    GAE support is improved in JRebel 3.x (file permissions as well), so try the nightly.

    With nightly build it works better but still I get an error. Now wicket displays an exception:

    Unexpected RuntimeException

    Root cause:

    If I add to rebel.xml exclusions for .html files JRebel successfully reloads classes but of course it doesn't refresh markup files.

    I was able to reproduce the same error.
    I'm trying to fix this and I'll let you know about the progress.

    Great!
    Seems like I never thought someone to use rebel.xml with GAE.
    Well! As we got you I finally added the integration.
    Get the new nightly and let me know if it solved the problem:
