Description

Web applications do not appear to run in the root application context in Karaf 2.2.0 (this is not an issue in Karaf 2.1.4). The problem is easily duplicated using the Tomcat sample WAR, as follows.

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 for /default/index.html, fails to find the page, and returns a not found error (see the log output below for more details).
