I have been struggling to get an web application to run in the root application context in Karaf 2.2.0 (it works fine in Karaf 2.1.4). I have been able to isolate the issue to something easily duplicated using the Tomcat sample WAR.

1. Run the following command from Karaf:

   osgi:install -s webbundle:http://tomcat.apache.org/tomcat-5.5-doc/appdev/sample/sample.war?Bundle-SymbolicName=tomcat-sample&Webapp-Context=/anything

2. Access the app from your web browser (http://localhost:8181/anything/index.html)

3. Uninstall the sample bundle

4. Reinstall the bundle using the root context path with the following command:

   osgi:install -s webbundle:http://tomcat.apache.org/tomcat-5.5-doc/appdev/sample/sample.war?Bundle-SymbolicName=tomcat-sample&Webapp-Context=/

5. Attempt to access the app from your web browser (http://localhost:8181/index.html)

6. Note the 404 error.

Looking at the logs, it appears that when a web app is in the root application context, it prepends a "/default/" to any request. For example, when trying to access /index.html it looks in /default/index.html, fails to find the page, and returns a not found error (see the log output below for more details).

Does anyone know how to resolve this issue?
