Hi, I successfully deployed my web service onto jboss application server. But it seems I can only successfully sent requests to my Windows server, and not the UNIX machine(RED HAT 9) I deployed my Web service using .ear, so I may include SUN metro libraries v1.3 hellometro.ear --HelloMetro.ear --WEB-INF/web.xml --WEB-INF/jboss-web.xml --WEB-INF/sun-jaxws.xml --META-INF --jboss-app.xml --application.xml --lib --webservices-api.jar --webservices-extra-api.jar --webservices-rt.jar --webservices-extra.jar I got the following exception; I am not sure what to make out of the exception but the soap version # might be wrong. I am using Jboss 4.2.2 GA and Jbossws 3.0.4. The web service code is compile using java 1.5. Any help is appropriated. Thank you! java.lang.ClassCastException: com.sun.xml.messaging.saaj.soap.ver1_1.Envelope1_1Impl at org.jboss.ws.core.soap.SOAPEnvelopeImpl.(SOAPEnvelopeImpl.java:57) at
