Sounds nice!

Sounds like you are avoiding a circular reference here.

Does this mean that you are exposing the servlet api through the
org.eclipse.equinox.servlet.bridge.extensionbundle bundle?

If yes, wouldn't it make more sense to expose them through the
org.eclipse.equinox.servlet.bridge.http bundle?

Wouldn't it make sense to register the JSPs in the same way?

Having no fixed prefix like "/jasper-jsp/" sounds great but I wonder if
this approach can be extended to work with any HttpService. I believe
several people here said they liked  to test their bundles in a
standalone OSGi runtime using either the Jetty-based HttpService or the
Equinox HttpService while deploying using the bridge servlet.

For me it would actually be a requirement that I retain the freedom to
choose which HttpService is used.
