Hi Deepal,
I don't know how can this happen.
My handler extends AbstractDispatcher and replaces
RequestURIBasedDispatcher and it's globally engaged. Please find
attached axis2.xml and module.xml.
In the default public constructor I have:
public NodeDispatcher() {
this.factory = (SOAP12Factory) OMAbstractFactory.getSOAP12Factory();
this.omNs = factory.createOMNamespace(SOAPConstants.URI,
SOAPConstants.NODE_PREFIX);
//Registers the node to the manager
try {
if (! registered) {
// Sends a message to another service running on another tomcat server
(it works)
BootstrapHelper.register(factory, omNs);
registered = true;
}
} catch (AxisFault e) {
if (log.isEnabledFor(Level.FATAL)) {
log.fatal("Unable to register the node: " +
e.getLocalizedMessage());
}
}
}
and Bootstrap.register is:
static final void register(SOAP12Factory factory, OMNamespace omNs)
throws AxisFault {
Options options = new Options();
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
ServiceClient sender = new ServiceClient();
EndpointReference managerEPR = new
EndpointReference(System.getProperty("qosp.manager.epr"));
OperationClient mepClient =
sender.createClient(ServiceClient.ANON_ROBUST_OUT_ONLY_OP);
mepClient.setOptions(options);
SOAPEnvelope env = createRegistrationEnvelope(factory, omNs);
MessageContext ctx = new MessageContext();
ctx.setEnvelope(env);
ctx.setWSAAction(ActionConstants.ADD_NODE_ACTION);
ctx.setTo(managerEPR);
mepClient.addMessageContext(ctx);
mepClient.execute(false);
mepClient.complete(ctx);
if (NodeDispatcher.log.isInfoEnabled()) {
NodeDispatcher.log.info("Node [" +
NodeDispatcher.getNodeName() + "]
registered.");
}
}
The exception is thrown after the handler is created.
Hope this helps,
Michele
