[jbossws-users] [JBossWS] - InvalidClassException running a webservice client

I'm trying to run a webservice client as described by the jbossws-userguide.pdf that goes with jbossws-1.0.4GA. I'm using jboss-4.0.5GA The client should connect to a JSR181 webservice. I use a J2EE application jar that should allow me to use JNDI to access the webapplication from my simple client. I get the following exception: | [java] 02:46:33,062 ERROR [ServiceObjectFactory] Cannot create service | [java] javax.naming.NamingException: Cannot unmarshall service ref meta data, cause: java.io.InvalidClassException: javax.xml.namespace.QName; local class incompatible: stream classdesc serialVersionUID = 4418622981026545151, local class serialVersionUID = -9120448754896609940 | [java] at org.jboss.ws.jaxrpc.ServiceObjectFactory.getObjectInstance(ServiceObjectFactory.java:126) | [java] at javax.naming.spi.NamingManager.getObjectInstance(Unknown Source) | [java] at org.jnp.interfaces.NamingContext.getObjectInstance(NamingContext.java:1125) | [java] at org.jnp.interfaces.NamingContext.getObjectInstanceWrapFailure(NamingContext.java:1142) | [java] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:705) | [java] at org.jboss.naming.client.java.javaURLContextFactory$EncContextProxy.invoke(javaURLContextFactory.java:135) | [java] at $Proxy0.lookup(Unknown Source) | [java] at javax.naming.InitialContext.lookup(Unknown Source) | [java] at Main.main(Unknown Source) | The source code of the client: | InitialContext iniCtx0 = new InitialContext(); | Hashtable env = iniCtx0.getEnvironment(); | env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming.client"); | env.put("j2ee.clientName", "jbossws-client"); | System.out.println(env); | InitialContext iniCtx = new InitialContext(env); | | MyFirstService service = (MyFirstService) iniCtx | .lookup("java:comp/env/service/MyFirstService"); | HelloIF port = service.getHelloIFPort(); | System.out.println(port.sayHello()); | I don't know what I'm doing wrong. Everything runs from ant scripts which are executed by Eclipse. Any help would be much apreciated View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040800#...
