I have developped a webservice using Axis2. The webservice uses mtom in order to send large files. When I call it from a client in a jboss server I am getting the following error: org.apache.axis2.AxisFault: java.lang.NullPointerException at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:486) at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(OutInAxisOperation.java:343) at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:389) at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:211) at org.apache.axis2.client.OperationClient.execute(OperationClient.java:163) at hcdSns.notificaciones.envio.WSProxyAttachementsStub.recepcion(WSProxyAttachementsStub.java:151) at hcdSns.notificaciones.envio.ClienteEnvioNotificacion.enviarMsgXL(ClienteEnvioNotificacion.java:80) at hcdSns.ciudadano.model.VerInformeHelper.envioHC007RecepcionHC008(VerInformeHelper.java:99) at hcdSns.ciudadano.action.VerInformeAction.doAction(VerInformeAction.java:40) I am also testing it in a Weblogic Server and it works ok and I get the file without any problem. Any idea? Thanks!call View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4182374#...
