jstl tags not getting displayed

[shijuppaul]

I have created an application with 4 Osgi bundles.
1) Model
2) Service Interface
3) Interface Implementation
4) UI (Spring MVC with JSTL tags)

These bundles are deployed to Equinox where Tomcat bundle is already deployed.

When i invoke the url, i can see Controller is getting the model but the model data is not getting displayed in the UI.

JSTL tags prints the expression as it is. ${helloWorld.message}

Not sure has it something to do with the bundles deployed into Equinox?

The same application is converted to Non-OSGI application and works fine in tomcat.

Equinox configuration file is as follows.

Any help will be appreciated.

It sounds like that the JSP/JSTL engine doesn't start properly and thus the pages are served as static content rather then dynamic pages. It would help first to use the latest stable versions of the libraries used (such as 1.2.1 instead of 1.2.0.m1 for Spring OSGi) and to enable logging (highest level possible) for Tomcat and Jasper.
