Subject [jira] Created: (AXIS-2720) Stub.setTimeout() sets the timeout for ALL Stubs rather than for the instance
Date Tue, 22 Jan 2008 22:06:37 GMT
Stub.setTimeout() sets the timeout for ALL Stubs rather than for the instance
-----------------------------------------------------------------------------

                 Key: AXIS-2720
                 URL: https://issues.apache.org/jira/browse/AXIS-2720
             Project: Axis
          Issue Type: Bug
          Components: Basic Architecture
    Affects Versions: 1.4
         Environment: Windows XP,
java version "1.5.0_08"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_08-b03)
Java HotSpot(TM) Client VM (build 1.5.0_08-b03, mixed mode)
            Reporter: Tim Cham


************************
* Use Case Problem:
************************

java.net.URL portAddress1 = new URL(endpoint);
IntegrationAPI2Service serviceLocator1 = new IntegrationAPI2ServiceLocator();
IntegrationAPI2 api1 = serviceLocator1.getIntegrationAPI2(portAddress1);
Stub stub1 = (Stub) api1;
stub1.setTimeout(1000); 

// The very first call will have a connection timeout and a read timeout of 1 second
api1.distanceSearchOfCategoriesAtCityState( ... ) ; 


java.net.URL portAddress2 = new URL(endpoint);
IntegrationAPI2Service serviceLocator2 = new IntegrationAPI2ServiceLocator();
IntegrationAPI2 api2 = serviceLocator2.getIntegrationAPI2(portAddress);
Stub stub2 = (Stub) api2;
stub2.setTimeout(6000); 

// All other calls will STILL have a timeout of 1 second even though
// we explicitly set the timeout for this particular call to 6 seconds.
// Thus the following line will throw a SocketException if the connection
// takes more than 1 second.
api2.distanceSearchOfCategoriesAtCityState( ... ) ; 

************************
* Code Problem
************************
org.apache.axis.components.net.SocketFactoryFactory

 public static synchronized SocketFactory getFactory(String protocol,
                                                        Hashtable attributes) {
        SocketFactory theFactory = (SocketFactory)factories.get(protocol);

        .....
 }

Notice that the hashtable of factories is only keyed in with the protocol, where it should
really be keyed in with both the protocol AND attributes (such as timeout).
