Subject AW: Axis2 WebService - Timer threads are accumuating and java.lang.OutOfMemoryError: unable to create new native thread
Date Tue, 30 Aug 2011 10:14:58 GMT
You expect to know:"it is a timer thread." 
May I ask you very kindly to tell us if you expect your timer thread 
to be on the service or the client side of the pond?
A minimum of information we need to maybe help you!
Josef

Betreff: Axis2 WebService - Timer threads are accumuating and java.lang.OutOfMemoryError:
unable to create new native thread


Hello,
We have a webapplication runnig on glassfish version 2.1 connecting to a
webservice using the piece of the code below. Every day we are having over
1000 calls. For some reason timer threads are getting accumalated day by
day. Couple of days after we are getting java.lang.OutOfMemoryError: unable
to create new native thread ... Which indicates probably some thing wrong
with code or some bug in axis2 which i am not aware of ... Please help ...
This is becoming a BIG BIG production issue for us. Appreciate your help in
this matter.

	public String CallWebService(String webServiceName, OMElement
webServiceRequest) throws Exception
	{
				ConfigurationContext ctx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem("/export/home/test",
"/export/home/test/conf/axis2.xml");
			
				ServiceClient client = new ServiceClient(ctx, null);
				Options options = new Options();
				client.setTargetEPR(new EndpointReference("URL"));
				options.setTo(new EndpointReference("URL"));
				options.setAction("URLACTION"+webServiceName);
				options.setTimeOutInMilliSeconds(90*1000);
				client.setOptions(options);		
		
		        	client.engageModule("addressing");
				client.engageModule("rampart");
				
				OperationClient  sender =
client.createClient(ServiceClient.ANON_OUT_IN_OP);
			    MessageContext mc = new MessageContext();
			    SOAPFactory fac = OMAbstractFactory.getSOAP11Factory();
			    SOAPEnvelope envelope=fac.getDefaultEnvelope();	
		
			    OMNamespace vis = fac.createOMNamespace("URLNAMESPACE", "emp");        
			    envelope.declareNamespace(vis);
		
			    envelope.getBody().addChild(webServiceRequest);
			    mc.setEnvelope(envelope);
			    sender.addMessageContext(mc);
					        
				String webserviceReponse = "";
		        try
		        {
		        	sender.execute(true);	
			        MessageContext responsemsg =
sender.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
					SOAPBody body = responsemsg.getEnvelope().getBody();
					webserviceReponse = body.toString();	

			            client.cleanup();
			            client.cleanupTransport();
			            client.disengageModule("addressing");
			            client.disengageModule("rampart");
			            sender.reset();
				}
				catch(AxisFault e)
				{
					System.out.println("Exception is"+e);
					e.printStackTrace();					
				}	

			return webserviceReponse;
	}
