Description Violeta Georgieva CLA 2012-11-27 05:07:44 EST 
Gemini Web cannot discover an annotated web component if it is outside of the WEB-INF/classes or WEB-INF/lib, but it is in the bundle class path (i.e. Bundle-Classpath: .,WEB-INF/classes).
Comment 1 Violeta Georgieva CLA 2012-11-27 05:08:36 EST 
If the web component is described in web.xml then it is working as expected.
Comment 2 Nobody - feel free to take it CLA 2013-01-21 06:00:19 EST 
It would be helpful to have some clarifications as we are seeing similar problems with Spring MVC apps.

Is this a WAB in which you specify Bundle-Classpath or is it a WAR in which the Bundle-Classpath has been generated during deployment?

Which annotations are causing the problem?

Thanks.

No, because Servlet Spec declares only WEB-INF/classes and WEB-INF/lib/*.jar for inclusion in the class loader. Gemini Web does not add '.' to the generated Bundle-Classpath. So in this case everything is working.

> Which annotations are causing the problem?

Those specified in Servlet Spec i.e. @WebServlet etc.


I checked Tomcat implementation and it is not trivial to add the additional class path to the processing (see org.apache.catalina.startup.ContextConfig.webConfig() -> // Step 4. Process /WEB-INF/classes for annotations). I will need more time to find a way to process this. I do not want to override webConfig() because we will need to copy almost the whole method.
