Hi,

I'm trying to expose an EJB through both a local business interface and a JAX-RS interface, but are getting the following error:

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.deployment.unit."finance.war".PARSE: org.jboss.msc.service.StartException in service jboss.deployment.unit."finance.war".PARSE: Failed to process phase PARSE of deployment "finance.war"

          ... 5 more

This i my code:

public interface FileService {
     ...
}

public interface FileServiceLocalBusiness extends FileService {
     ...
}

@Path("file")
@Consumes({ "application/json" })
@Produces({ "application/json" })
public interface FileServiceWs extends FileService {
     ...
}

@Stateless
@Local({FileServiceLocalBusiness.class, FileServiceWs.class})
public class FileServiceImpl implements FileServiceLocalBusiness, FileServiceWs {
     ...
}

I have been trying to follow this guide http://pic.dhe.ibm.com/infocenter/wasinfo/v8r0/index.jsp?topic=%2Fcom.ibm.websphere.base.doc%2Finfo%2Faes%2Fae%2Ftwbs_jaxrs_ejb_nointerface.html but I must be misunderstanding something.

Any suggestions to point me in the right direction would be appreciated.
