Hello,
In JBoss 4.2.3GA, JBossWS 3.1.1-native when you name POJO web service endpoint with suffix "Servlet" then it cannot be call due to exception:
{code}java.lang.ClassCastException: package.name.MyWsServlet cannot be cast to javax.servlet.Servlet{code}
Pojo servlet code:
{code}
package ws;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public class MyWebServiceServlet {
@WebMethod
public void hello() {
System.out.println("MyWebServiceServlet.hello()");
}
}
{code}
web.xml
{code}
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns=" http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"

<servlet-class>ws.MyWebServiceServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyWebService</servlet-name>
<url-pattern>/MyWebService</url-pattern>
</servlet-mapping>
</web-app>

*When I rename servlet to MyWebService everything works fine... I thing it's a bug.*
I've tested in on windows platform, Java 6
