Connection is not released while using JAXWS client API
-------------------------------------------------------
Key: AXIS2-5062
URL: https://issues.apache.org/jira/browse/AXIS2-5062
Project: Axis2
Issue Type: Bug
Components: jaxws, transports
Affects Versions: 1.7.0
Reporter: Ivan
1. Using Dispatch API
A bit more description for my case, the server side is a simple web service,
for the client side, the codes are something like :
--->
Service service = new HelloService();
Dispatch dispatchJaxb = service.createDispatch(PORT_QNAME,
JAXBContext.newInstance(org.test.ObjectFactory.class),
javax.xml.ws.Service.Mode.PAYLOAD);
dispatchJaxb.invokeOneWay(new HelloRequest());
<---
After adding some code fragments in the finally block of
BaseDispatch.invokeOneWay method, it looks to me work fine.
--->
try {
if (requestMsgCtx != null &&
requestMsgCtx.getAxisMessageContext() != null) {
org.apache.axis2.context.MessageContext axisMsgCtx =
requestMsgCtx.getAxisMessageContext();
if (axisMsgCtx.getTransportOut() != null &&
axisMsgCtx.getTransportOut().getSender() != null) {
axisMsgCtx.getTransportOut().getSender().cleanup(axisMsgCtx);
}
}
} catch (Exception ignore) {
}
<---
I also googled this issue, and do found a lot of information for the same
timeout exception, also read some related codes
a. In the HttpSender, there is a method named cleanup, which is used to release
the connection, but it has the precondition to configure the
AUTO_RELEASE_CONNECTION. And actually I did not see other setting
configurations in the Axis2 codes, and think that it should be configured by
the users in the Options ?
b. Some posts in the mail list recommended to call the getTransport().cleanup()
in the Axis2 specific client codes. And in the testing scenario above, since
the standard JAX-WS API is used, suppose that Axis2 should do this ?
And very appreciated with any comment ? Thanks.
2. I might find another connection leak while using JAXWS API on client side.
In the scenario below :
For the server side, it requires basic authentication.
The client codes are something like :
HelloPort helloPort = (HelloPort)service.getPort(HelloPort.class);
helloPort.echo("hello");
The client codes did not set the user name and password by the BindingProvider
interface, so the server return a 404 to the client side, then the method
HttpSender.handleResponse will enter the fourth block :
private void handleResponse(MessageContext msgContext,
HttpMethodBase method) throws IOException {
int statusCode = method.getStatusCode();
log.trace("Handling response - " + statusCode);
if (statusCode == HttpStatus.SC_OK) {
// Save the HttpMethod so that we can release the connection when
cleaning up
msgContext.setProperty(HTTPConstants.HTTP_METHOD, method);
processResponse(method, msgContext);
} else if (statusCode == HttpStatus.SC_ACCEPTED) {
/* When an HTTP 202 Accepted code has been received, this will
be the case of an execution
* of an in-only operation. In such a scenario, the HTTP
response headers should be returned,
* i.e. session cookies. */
obtainHTTPHeaderInformation(method, msgContext);
// Since we don't expect any content with a 202 response, we
must release the connection
method.releaseConnection();
} else if (statusCode == HttpStatus.SC_INTERNAL_SERVER_ERROR ||
statusCode == HttpStatus.SC_BAD_REQUEST) {
// Save the HttpMethod so that we can release the connection when
cleaning up
msgContext.setProperty(HTTPConstants.HTTP_METHOD, method);
Header contenttypeHeader =
method.getResponseHeader(HTTPConstants.HEADER_CONTENT_TYPE);
String value = null;
if (contenttypeHeader != null) {
value = contenttypeHeader.getValue();
}
OperationContext opContext = msgContext.getOperationContext();
if(opContext!=null){
MessageContext inMessageContext =
opContext.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
if(inMessageContext!=null){
inMessageContext.setProcessingFault(true);
}
}
if (value != null) {
processResponse(method, msgContext);
}
if
(org.apache.axis2.util.Utils.isClientThreadNonBlockingPropertySet(msgContext)) {
throw new AxisFault(Messages.getMessage("transportError",
String.valueOf(statusCode),
method.getStatusText()));
}
} else {
throw new AxisFault(Messages.getMessage("transportError", <---
Running here
String.valueOf(statusCode),
method.getStatusText()));
}
}
The stack trace is :
