Timeout for Webservice response?

Question

I have a client that calls a webservice. Partly some of the called methods may take a long time to complete on the server (even up to 1 hour). I want the client to wait for the response for that time, thus keeping the connection alive!

I tried to set the following property within the client, but without success:

((BindingProvider)port).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 0); //0 for disabling any timeouts

I'm still getting Timeout Exception after some time. Which property has to be set to prevent the following error?

Answer 1

Are you sure that this is a client side timeout? Did you configure your server transaction timeout properly?

For client side timeout you need in your cxf configuration:

<http-conf:conduit name="*.http-conduit">
    <http-conf:client ConnectionTimeout="your connection timeout" ReceiveTimeout="your receive timeout"/>
</http-conf:conduit>

Timeouts are expressed in milliseconds.

In Java code you need get the HTTPConduit and then set HTTPClientPolicy:

see from http://cxf.apache.org/docs/client-http-transport-including-ssl-support.html

  import org.apache.cxf.endpoint.Client;
  import org.apache.cxf.frontend.ClientProxy;
  import org.apache.cxf.transport.http.HTTPConduit;
  import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;
  ...

  URL wsdl = getClass().getResource("wsdl/greeting.wsdl");
  SOAPService service = new SOAPService(wsdl, serviceName);
  Greeter greeter = service.getPort(portName, Greeter.class);

  // Okay, are you sick of configuration files ?
  // This will show you how to configure the http conduit dynamically
  Client client = ClientProxy.getClient(greeter);
  HTTPConduit http = (HTTPConduit) client.getConduit();

  HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();

  httpClientPolicy.setConnectionTimeout(your connection timeout); 
  httpClientPolicy.setAllowChunking(false);
  httpClientPolicy.setReceiveTimeout(your receive timeout);

  http.setClient(httpClientPolicy);

  ...
  greeter.sayHi("Hello");

Update

For your java.lang.ClassCastException make sure that com.sun.xml.ws.client.sei.SEIStub is not in classpath or ensure that cxf jar is before Sun's jaxws RI jar in the classpath. For example try removing jaxws-rt*.jar from your classpath.
