[equinox-dev] Accessing Plugins from WAS


I'm using WAS 6.1.  I have constructed Web Services using the wizards in AST 6.1.  I want the implementation of these services to call plugin code.  I know that there are several problems here - including the fact that WAS 6.1 uses Eclipse 3.1 plugins, and the functionality I seek is more related to Eclipse 3.2.

It was suggested that I use the Equinox bridge.  This seems difficult, because the servlets that I'm using are created via the wizards in AST, and I find it hard to determine how I would register them so the bridge could access them.


What I decided to do instead was to subclass the FrameworkLauncher, removing most of the servlet references (and currently hardcoding the access to the bridge war, which contains my plugins that I need).  Looking at the BridgeServlet code, it changes the context classloader of the running thread, and then calls the proxy servlet, which will call the registered servlet.  I figured, that I could create the appropriate context classloader using my FrameworkLauncher class, and then before I try to load the first plugin class, I would change the context classloader to the one I just created.


This seemed to almost work, but the context classloader was not able to load/find any plugin classes, beyond the ones related to the framework itself.  On the other hand, the framework started just fine, and loaded all of my bundles.  However, when I look at the context classloader that is created, it seems like there is no connection between it and the bundle classloaders created by the framework.


Am I just on the wrong track?  Is what I'm trying to do just silly??  Is there any hints you can provide??


Any help would be greatly appeciated!
