OSGi bundles with OSGi WAB
Question
I'm kinda new to develop OSGi bundles and OSGi WAB. I'm using Jboss AS 7.1 server in which I should use both OSGi bundles and WAB together. Few of my dependencies for WAB are OSGi bundles, both the bundles and WAB are inside 'deployments' folder of my server. When I deploy my WAB, it looks for the dependencies inside 'WEB-INF/lib'. How to include the bundles for dependencies which are outside the WAB file without adding those bundles in 'WEB-INF/lib'?
Thanks in advance.
EDIT:
I followed the steps provided in this link:
http://www.rpgnextgen.com/wiki/doku.php?id=vaadin_7.4_osgi_web_application
I was successful in creating a WAB file. I have all the necessary Vaadin dependencies deployed as OSGi bundles in my server under 'deployments' folder. When I deploy my WAB file, the Vaadin dependencies under 'deployments' folder are not included but the WAB file is looking for Vaadin dependencies inside 'WEB-INF/lib' path. The below is the pom.xml I'm using.

Basically what I'm trying to do is to create a WAB project which uses other bundles for dependencies instead of using 'WEB-INF/lib' inside the .war file.
When I deploy the war file to the server, I end up getting the below exception:

Ok, that's a real old version of Pax-Web (current version is 4).
The reason for this behavior is, to also give an explanation to @NeilBartlett, to be able to get a hold of all possible taglibs.
The Pax-Web Container traverses the imported bundles and does look for taglibs in this bundle to make them available to the JSP JasperCompiler.
This is one of the parts that has been improved over time. The way it's done in 1.x of Pax-Web was a bit "brute-force" but requires the container to give back valid "bundle" URIs. Looks like JBoss container compared to std. Felix and Equinox works different.
