Integration

Hi,

I am into migration of a desktop applciation to web application using ADF. In my application I perform Tuxedo call through WTC using . I have a tuxedo service that takes more time to give reply (around 2 minutes). When I try to do this service call through WTC, it gives me TPException with tperrno as 12 (TPED_INVALIDCONTEXT). Code i use to perform tuxedo call is given below

    public TypedFML32 callTuxedo(String pServiceName, TypedFML32 pRequestBuffer)
    {
        TypedFML32 tuxReplyFML32 = null;
        TuxedoConnection tuxConn = null;
        Reply tuxReplyBuffer = null;
        try
        {
            tuxConn = TuxedoServiceLocator.getLocator().getTuxedoConnection();
            System.err.println("TP Call start time " + new Date());
            tuxReplyBuffer = tuxConn.tpcall(pServiceName, pRequestBuffer, 0);
        }
        catch (TPReplyException tre)
        {
            System.err.println("TP Call End time " + new Date());
            // tpCall is done but it throws application validation error. Show error message to user.
        }
        catch (TPException tpee)
        {
            // Tuxedo call failed due to connectivity issue.
            int tperrNo = tpee.gettperrno();
            System.err.println("TO Error " + tperrNo);

        }
        finally
        {
            // Closing the association with Tuxedo
            if (tuxConn != null && !tuxConn.isTerminated())
            {
                tuxConn.tpterm();
            }
        }
        //Convert to typed FML 32 buffer
        tuxReplyFML32 = (TypedFML32) tuxReplyBuffer.getReplyBuffer();
        return tuxReplyFML32;
    }

In the Weblogic server, I've set the Connection Policy of local access point as 'ON STARTUP' and remote access point as 'ON DEMAND'.

Questions:

1. I want to know whether my tuxedo call implmentation is correct.
2. What makes my tuxedo call to return tperrno 12 and how can I resolve this. (In the older desktop application this service call takes nearly 2 minutes but works)

Your timely help would be appreciated. Thanks.
