Java Webservice java.lang.ClassCastException: org.apache.cxf.jaxws.ServiceImpl

Question

I am using Maven, CXF 2.2.7, JBoss 4.2.3 and JRE 1.5 Updated

I have a Webservice that I can see on the server by using the URL myURL/myService?wsdl

I am trying to develop a web app to ping that webservice by calling this in my bean:

MyWebService webservice = new MyWebService();

However, it dies and throws the following error, which is very vague:

I am hoping someone has seen this exception before and can help me.

Answer 1

This is most likely a classloader issue where multiple classloaders are loading the jaxws api classes. My main thought would be to check the classloaders and wars and endorsed areas and such for any of the jaxws-api jars and make sure it's only found in one place.

Answer 2

I've worked around this JBoss classloader issue by using the following code:

import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPFaultException;
import javax.xml.ws.spi.ServiceDelegate;
import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.jaxws.ServiceImpl;

Bus bus = BusFactory.newInstance().createBus();
ServiceDelegate service = new ServiceImpl(bus, url, portName, null);
Dispatch<Source> dispatch = service.createDispatch(portName, Source.class, Service.Mode.MESSAGE);
