Hi again, Does anyone solve this problem? I am still looking for a solution. I tried what I found in Jboss forums and I did not make it work. This is what I get when using my web service client: Caused by: java.lang.ClassCastException: org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl | at javax.xml.ws.Service.<init>(Service.java:81) | The only thing I did was upgrade jbossws version from 3.0.4 (it worked perfectly) to 3.1.0 Thanks in advance!
