Hi, I am trying to deploy a rap application to a tomcat app server. I
started trying the example from
http://eclipsesource.com/blogs/2007/12/07/rap-deployment-par t-2-deploying-your-application-as-a-war-file/

I realized that for the current version of RAP (Helios M4) I needed to add
org.eclipse.help to the feature to fulfill the OSGI dependencies.

Now that the app finally starts it throws an exception that I can not
interpret. Maybe someone here can help me:

SEVERE: Servlet.service() for servlet equinoxbridgeservlet threw exception
java.lang.ClassNotFoundException:
org.eclipse.swt.internal.widgets.displaykit.DisplayLCAFacade Impl

....


The OSGI console looks good:

osgi> ss

Framework is launched.

Hi Lothar,

you're missing the RWT Fragment with all the client-side stuff (qooxdoo,
widget LCAs, etc). Be sure to include org.eclipse.rwt.q07 fragment in
your deployment and your config.ini.

Regards,
Benny
