Weblogic在JAX-WS Client中卡住了线程

Question

My web application front end runs on its own dedicated weblogic server. My webservices are deployed on a different server machine, on weblogic.

I consume webservices this way:

URL url = new URL("http://xxx:7001/corpevent/rightsservice?wsdl");
QName qname = new QName("http://corpevent.service.org/", "rightsservice");

Service service = Service.create(url, qname);
RightsIssueService ri = service.getPort(org.service.corpevent.RightsIssueService.class);
ri.callMethod();

It works fine, but sometimes I get stuck thread issues. I have tried to figure out how to stop it from happening but everything I've tried hasn't worked so far.

Here is the stack trace:

I read somewhere that JAX-WS isn't thread safe. Am I implementing it wrong, in my case?

Answer 1

The problem with this was the network connection between my front-end server and my middleware server (which holds the weblogic server). I got a new server, got VM Ware instead of the Hyper-V I was using, and everything's sorted.

The middleware application is installed on a RHEL (Red Hat Enterprise Linux)
