Amila Chinthaka Suriarachchi commented on AXIS2-4330:
-----------------------------------------------------
The reason for this problem is that by default Axis2 creates a new Http client
(hence a connection manager) and this connection manager shuts down only when
it time out.
So you need to create a connection manager *per thread* and close it before
thread exists
public class MyThread extends Thread {
private ServiceConnection serviceConnection = null;
public void run() {
serviceConnection = new ServiceConnection(address, pWord);
while (true) {
batchResultSet = getNewBatchData();
while (batchResultSet.next()) {
request = buildWebRequest(batchResultSet);
// calling web service for each request
response = serviceConnection.crCpu4(request);
batchResultSet.close();
}
}
// have to call this after while loop once it exists
serviceConnection.shutDown();
}
}
public class ServiceConnection {
private TuxedoWebServiceStub tuxService;
private TuxedoWebServiceStub.CRAN_CPU4WS inquiryReq = null;
MultiThreadedHttpConnectionManager httpConnectionManager = null;
public ServiceConnection(String url, String passwd) throws Exception {
httpConnectionManager = new MultiThreadedHttpConnectionManager();
HttpClient httpClient = new HttpClient(httpConnectionManager);
tuxService = new TuxedoWebServiceStub(url);
tuxService._getServiceClient().getOptions().setProperty(HTTPConstants.REUSE_HTTP_CLIENT,
Constants.VALUE_TRUE);
tuxService._getServiceClient().getOptions().setProperty(HTTPConstants.CACHED_HTTP_CLIENT,
httpClient);
inquiryReq = new TuxedoWebServiceStub.CRAN_CPU4WS();
}
public String crCpu4(String request) {
inquiryReq.setInbuf(request);
TuxedoWebServiceStub.CRAN_CPU4WSResponse inquiryRep =
tuxService.CRAN_CPU4WS(inquiryReq);
if (inquiryRep != null)
return inquiryRep.getOutbuf();
return null;
}
public void shutDown(){
httpConnectionManager.shutdown();
}

> Environment: solaris
> Reporter: jenny anderson
> Attachments: TuxedoWebServiceStub.java

>
> My application is using axis2 web service. It invokes web service thousand
> times per second. We observed thousand CLOSE_WAIT connection after the
> application is run for less than 10 hours. I checked even I set
> REUSE_HTTP_CLIENT to false, it still gets CLOSE_WAIT.
