<div class="jive-rendered-content"><p><span style="font-family: helvetica;">Hi Everyone,</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: helvetica;">I am new to JBoss, and Java Web development in general.  We are currently examining SOA based solutions for a future software development project, and we have been working with both JBoss and Glassfish for testing.  Right now, we have been able to get a simple Java Web Service and REST Web Service created in Netbeans and Glassfish.  This process was rather simple.</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: helvetica;">We are now trying to do the exact same thing with JBoss and Eclipse.  Thus far, this has been a complete and utter <strong>NIGHTMARE</strong>!  I don't understand whether my problem is with Eclipse, JBoss, or both.</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: helvetica;">I have created a simple web service following the insturctions posted here: </span></p><p><a class="jive-link-external-small" href="http://community.jboss.org/docs/DOC-15778" target="_blank">http://community.jboss.org/wiki/UsingTheSampleWebServiceWizards</a><span> .</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>It seemed simple to follow, however, I am unable to access the WSDL file and the web service tester tool with the ?wsdl and ?tester urls appended to the web service path.  I followed the JAX-WS example exactly, with the same names used for the example, and I am getting this error while accessing the ?wsdl page:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;">java.lang.ClassCastException: org.jboss.samples.webservices.HelloWorld cannot be cast to javax.servlet.Servlet</span></p><p><span style="font-family: courier new,courier;"> org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:139)</span></p><p><span style="font-family: courier new,courier;"> org.jboss.as.web.NamingValve.invoke(NamingValve.java:57)</span></p><p><span style="font-family: courier new,courier;"> org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)</span></p><p><span style="font-family: courier new,courier;"> org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:362)</span></p><p><span style="font-family: courier new,courier;"> org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877)</span></p><p><span style="font-family: courier new,courier;"> org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:667)</span></p><p><span style="font-family: courier new,courier;"> org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:952)</span></p><p style="min-height: 8pt;
