Number of HTTP sessions increasing

[Josh123 <jo...@gmail.com>]

Hi,
I am using Axis 2 client to access a web service written using .net.
The client gets a record from the database, convert it into SOAP message,
and sends it to service, gets a response back and process the record in the
database, and then gets another record and so on.

Now when I start the process and run netstat on the client machine, I see
number of connections to server and database increasing drastically. (in
couple of minutes it reaches 200 to 300) and after some time i start getting
socket errors on the server side.
Now
1. Is the socket error caused due to these http sessions opened in excess?
2. Is it normal when using Axis 2 client for sending multiple records
(synchronously), to have multiple http sessions, or have I messed up in my
code?

Any help will be appreciated.

I have generated the client side service stub using WSDL2JAVA and the code
to invoke the service stub is as follow:
public class Client {
	
	private static ServiceStub service;
	
	private static void getService(String endPointUrl) throws AxisFault{
		if (service == null){
			service = new ServiceStub(endPointUrl);
		}
	}

	public static Response sendData(Object obj,
			String endPointUrl, long socketTimeOut, String userName,
			String password) {
		Operation operation = (Operation) obj;
		OperationResponse response = new OperationResponse();
		try {
			getService(endPointUrl);

			Authenticator auth = new Authenticator();

			auth.setUsername(userName);
			auth.setPassword(password);
			auth.setPreemptiveAuthentication(true);
			service._getServiceClient().getOptions().setProperty(
					org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE,
					auth);

			response = service.Operation(operation, socketTimeOut);
		} catch (AxisFault e1) {

			e1.printStackTrace();
		} catch (RemoteException e) {
			e1.printStackTrace();
		} catch (Exception e) {
			e1.printStackTrace();
		}
		return response;
	}
}
