Using Struts with SpringSource dm server gives Http Status 503 error

I developed an enterprise application using spring, struts and hibernate, now I want to transfer it to work with OSGi dm server.

I found a book "Pro SpringSource d开发者_如何学Pythonm server" where the author has explained a way to migrate WAR to OSGi bundles. I successfully migrated the application given in book.

The first step of migration says that remove the lib folder in WEB-INF directory and import all the relevant packages. I did the same. Application has been successfully deployed in the dm server.

But when I tried to connect to URL it is giving me the error:

SpringSource dm Server - Error report

HTTP Status 503 - Servlet action is currently unavailable

type: Status report message: Servlet action is currently unavailable

description: The requested service (Servlet action is currently unavailable) is not currently available.

What could be the reason for this?

I am out of clues to solve this issue. Can you pass any help you may have.

Thanks in anvance.

This is most likely because the WAR didn't deploy properly. The container seems to have have some idea that the webapp/servlet is there, but because it didn't start up correctly, it's not available.

Check your logs carefully, make sure dmServer indicates correct startup of the war and its servlets.
