Hello,

I've been trying to get Apache Felix webconsole going in a bare Virgo kernel distribuion but I have been puzzled by that the appearance is not the same as when executed in a "naked" Equinox setup. More specifically, in the Virgo kernel the webconsole's stylesheets and javascripts don't seem to be handled correctly. Digging deeper, I found that it is the ExtensionsHookConfigurator that seems to be causing problems since when taken out of the equation the webconsole displays as it should.

How to reproduce?
First, you need to download the following bundle files and add them under lib/kernel
https://ebr.springsource.com/repository/app/bundle/version/d ownload?name=com.springsource.javax.servlet&version=2.5. 0&type=binary
http://repo2.maven.org/maven2/org/ops4j/pax/web/pax-web-jett y-bundle/0.8.1/pax-web-jetty-bundle-0.8.1.jar
http://apache.dataphone.se//felix/org.apache.felix.webconsol e-3.1.6.jar

Then make the following configuration changes:

First, add the bundles to the lib/org.eclipse.virgo.kernel.launch.properties file.

  file:lib/kernel/org.eclipse.virgo.kernel.deployer-2.1.0.RELEASE.jar@start,\
  file:lib/kernel/org.eclipse.virgo.kernel.model-2.1.0.RELEASE.jar@start,\
  file:lib/kernel/org.eclipse.virgo.kernel.kerneldmfragment-2.1.0.RELEASE.jar,\
- file:lib/kernel/org.eclipse.virgo.kernel.shell-2.1.0.RELEASE.jar@start
+ file:lib/kernel/org.eclipse.virgo.kernel.shell-2.1.0.RELEASE.jar@start,\
+  file:lib/kernel/com.springsource.javax.servlet-2.5.0.jar@start,\
+  file:lib/kernel/pax-web-jetty-bundle-0.8.1.jar@start,\
+  file:lib/kernel/org.apache.felix.webconsole-3.1.6.jar@start

Second, we turn off the user region for these tests.
In config/org.eclipse.virgo.kernel.userregion.properties comment out the following lines:

-baseBundles = \
- file:lib/kernel/org.eclipse.virgo.kernel.userregion-2.1.0.RELEASE.jar@start,\
- file:lib/kernel/org.eclipse.virgo.kernel.osgicommand-2.1.0.RELEASE.jar@start
+# baseBundles = \
+#  file:lib/kernel/org.eclipse.virgo.kernel.userregion-2.1.0.RELEASE.jar@start,\
+#  file:lib/kernel/org.eclipse.virgo.kernel.osgicommand-2.1.0.RELEASE.jar@start

Now, start Virgo via the startup script (NOTE: ExtensionsHookConfigurator is enabled) and go to http://localhost:8080/system/console.
Note that the page appearance is quite bleak.

Now, try the same thing with the ExtensionsHookConfigurator disbabled:
Comment out the following line in lib/org.eclipse.virgo.kernel.launch.properties and then restart Virgo.

-osgi.hook.configurators.include=org.eclipse.virgo.osgi.extensions.equinox.hooks.ExtensionsHookConfigurator
+#osgi.hook.configurators.include=org.eclipse.virgo.osgi.extensions.equinox.hooks.ExtensionsHookConfigurator

Now, the appearance of the webconsole page is a lot more sophisticated.
Is this a bug in the ExtensionsHookConfigurator?

Well, it's either a bug or a subtle interaction between Virgo's Equinox hooks and this particular application.

We'll need to carve out some time to delve into this. This week we have a Virgo F2F meeting and the week after we have some urgent work to do on the tooling, so this will have to go into the backlog.

On the assumption that there is a bug, please would you raise a bugzilla so we don't lose track of this. Thanks.
