Hi All,
It worked like a charm. We used the Non-OSGi approach to access the JNDI
context. This is the way I did, added "org.wso2.carbon.jndi.feature" and
you can get service instance with;
Context context = new InitialContext();
Object serviceInstance =
context.lookup("osgi:service/org.wso2.carbon.uuf.core.create.RenderableCreator");
Regards,
Rasika
