I can work round it but I think there issomething wrong in the dpeloyment model.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-java">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
