Running Equinox on Application [message #131920]

I am trying to deploy equinox bundles (servlet and jsps) on IBM WAS6

As per my understand that there are two deployment options -
1. running Application server on top of Equinox (embedding an application
server) and
2. Running Equinox on top of an Application server.

Going with option 2... everything works fine, if i deploy cataline and
jasper as bundles on top of equinox.
However, I am thinking, Isn't application server supposed to provide these
servlet container and JSP compiler (and also other features security,
messaging , transaction etc)

How can I make use of servlet container which is there in IBM WAS6.1 (or
rather any application server) while running equinox in an app server.

Thanks your help.

Hi Krishnarajah,

Are you running under the servletbridge? If not I think this is what you're
looking for.

The servletbridge allows you to use the appservers servlet engine to safely
(from a modularity perspective) tunnel requests into and out of the Equinox
sandbox. Some folk using the servletbridge have set things up so they can
call out to EJBs and access messge queues etc. but it requires a decent
understanding of OSGi and in particular how to extend the framework
extension technique the servletbridge uses to expose more than just the
servlet API. The JSP support offered by the various app servers
unfortunately breaks modularity so that support does require embedding
Jasper however it's a decent engine and the consistent testability story
really helps.

A good place to start looking to learn more is the tutorials/presentations
offered at Eclipsecon in past years on "Building Server-side Equinox
Applications" I'm not sure if the slides for 2009 are up yet but I believe
the 2008 slides are posted.
