On trying to run a SOAP client I get: | Exception in thread "main" java.lang.ClassCastException: com.sun.xml.internal.messaging.saaj.soap.ver1_1.Message1_1Impl cannot be cast to com.sun.xml.messaging.saaj.soap.MessageImpl | at com.sun.xml.rpc.client.dii.CallInvokerImpl._postSendingHook(CallInvokerImpl.java:305) | at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:324) | at com.sun.xml.rpc.client.dii.CallInvokerImpl.doInvoke(CallInvokerImpl.java:103) | at com.sun.xml.rpc.client.dii.BasicCall.invoke(BasicCall.java:486) | at com.sun.xml.rpc.client.dii.CallInvocationHandler.doCall(CallInvocationHandler.java:121) | at com.sun.xml.rpc.client.dii.CallInvocationHandler.invoke(CallInvocationHandler.java:85) | at $Proxy0.uploadNewRegistrations(Unknown Source) | On JBoss I receive: | [03 Oct 2007 17:30:25] ERROR org.jboss.ws.core.jaxws.SOAPFaultHelperJAXWS - SOA | P request exception | org.jboss.ws.WSException: Cannot find child element: arg0 | at org.jboss.ws.core.CommonSOAPBinding.getParameterFromMessage(CommonSOA | PBinding.java:891) | at org.jboss.ws.core.CommonSOAPBinding.unbindRequestMessage(CommonSOAPBi | nding.java:343) | I'm using JBoss4.2.1GA with JBossWS-2.0.1 The first exception seems related to the fact I'm using JDK 6...but jboss-saaj.jar is indeed in libs/endorsed which I believe should resolve that problem.
