Hi guys,

I found another problem deploying the XTS interop tests to AS7. I can work round it but I think there issomething wrong in the dpeloyment model.

The deployment is a war which includes a junit jar in WEB-INF/lib and a mix of servlet classes and JaxWS endpoint implementation classes in WEB-INF/classes. When I deploy the web-app the JaxWS endpoint classes are not recognised as JaxWS endpoints even though they do have WebService annottaions (thsi is not a missing depenendencies problem -- the annotations do exist on the class).

12:39:13,100 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/sc007]] (MSC service thread 1-3) Servlet /sc007 threw load() exception: java.lang.ClassCastException: com.jboss.transaction.wstf.webservices.sc007.sei.ParticipantPortTypeImpl cannot be cast to javax.servlet.Servlet

It turns out that the problem is to do with the presence of both a WEB-INF classes directory and WEB-INF/lib jars. I stopped the debugger in WSDependenciesProcessor.isJaxwsJseDeployment() and identified the problem.

        private boolean isJaxwsJseDeployment(final DeploymentUnit unit) {
        final boolean isWarDeployment = DeploymentTypeMarker.isType(DeploymentType.WAR, unit);
        if (isWarDeployment) {
            final Index index = ASHelper.getRootAnnotationIndex(unit);
            final WarMetaData warMetaData = ASHelper.getOptionalAttachment(unit, WarMetaData.ATTACHMENT_KEY);
            if (warMetaData != null && warMetaData.getWebMetaData() != null) {
                return (ASHelper.selectWebServiceServlets(index, warMetaData.getWebMetaData().getServlets(), true).size() > 0);
            }
        }
 
        return false;
    }


The problem is that call to ASHelper.getRootAnnotationIndex. The deployment has two entries in its annotation map, one for the stuff in WEB-INF/lib and another for the stuff in WEB-INF/classes. getRootAnnotationIndex picks the first one it finds with the MODULE_ROOT_MARKER tag. Unfortunately both of them have this tag and it returns the one for WEB-INF/lib losing all info about the annotations on classes in WEB-INF/classes.

I suppose this is an AS problem more than a WS one but its definitely going to cause some difficulties for WS users.
