Jax WS Client code Blocking issue

[Nishant Chandra]

Hi All,

I have problem with the sync client code generated using wsdl2java for
a JAX-WS service. I see the following exception in logs:

"TP-Processor2070" daemon prio=10 tid=0x00002aaac4cf0800 nid=0x161c
waiting for monitor entry [0x00000000456de000]

We are using a singleton instance of the EServiceClient across our App:

class EServiceClient {

private static EServiceClient client = new EServiceClient();

public static MyServiceClient getInstance() {
return client;
}

private RecommendationsServiceClient() {
initClient();
}

private void initClient() {

try {
URL wsdlURL = EService.WSDL_LOCATION;
EService ss = new EService(wsdlURL, SERVICE_NAME);
port = ss.getEServicePort();
RECIEVE_TIMEOUT = new Long(timeout);
CONNECTION_TIMEOUT = new Long(conTimeOUt);
final Client cl = ClientProxy.getClient(port);
final HTTPConduit http = (HTTPConduit) cl.getConduit();
final HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setReceiveTimeout(RECIEVE_TIMEOUT);
httpClientPolicy.setAllowChunking(false);
httpClientPolicy.setConnectionTimeout(CONNECTION_TIMEOUT);
http.setClient(httpClientPolicy);
} catch (Exception e) {
e.printStackTrace();
}
}

Is it that the 'port' is not thread safe that I am seeing this
exception? How can I fix it?
The other problem is that connection timeout values are not honored.
Please help.
