Hi,

I am a bit confused about how webservice integration in AS7 depends on sub-deployment "containers".

I have an EAR that contains a WAR to be deployed.
- The EAR lib/ folder contains all stuff generated from a WSDL (using JAXWS-RI)
- The WAR contains an annotated webservice class (class with a @WebService annotation) plus another webservice implementation for the WSDL mentioned above
- The web.xml file (+webservices.xml +mappings.xml) mentions both webservices and both work fine.

If I move the annotated webservice class and the other webservice implementation class files (JARs) from the WAR to EAR's lib directory, a lot of strange warnings like
10:38:56,124 WARN  [org.jboss.ws.metadata.builder.jaxrpc.JAXRPCMetaDataBuilder] (MSC service thread 1-1) Guess java type from package mapping: [xmlType={NAMESPACE}XSDObject javaType=com.mycompany.LocationSearchRequest]
occur during startup and both webservices are not accessible:

The annotated webservice says:

10:43:28,830 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/demo].[SuperService]] (http--127.0.0.1-8080-1) Allocate exception for servlet SuperService: java.lang.ClassCastException: com.mycompany.MySuperWebservice cannot be cast to javax.servlet.Servlet

The webservice implementation says:

Is this a bug or is it not possible to place the webservice implementations outside the WAR, if referenced in web.xml ?
