Client API problem

[Fan, Jan-fon]

Hi,

I am using AXIS2C client api in my application to access web services which is developed with .NET.

The way that I send my request is as below:

 

    /* Send request */

    ret_node = axis2_svc_client_send_receive(svc_client, env, payload);

 

    if (ret_node)

    {

        axis2_char_t *om_str = NULL;

        om_str = axiom_node_to_string(ret_node, env);

        if (om_str)

            printf("\nReceived OM : %s\n", om_str);

        printf("\nclient invoke SUCCESSFUL!\n");

 

        AXIS2_FREE(env->allocator, om_str);

        ret_node = NULL;

    }

    else

    {

        AXIS2_LOG_ERROR(env->log, AXIS2_LOG_SI,

                        "Stub invoke FAILED: Error code:" " %d :: %s",

                        env->error->error_number,

                        AXIS2_ERROR_GET_MESSAGE(env->error));

        printf("client invoke FAILED!\n");

        }

 

I have 2 questions:

1. I send my requests in a loop. Inside the loop, I keep sending about 30 requests to the same web service. Sometime one or more requests would print out “client  invoke FAILED”. What could be the reason that causes this problem?

 

2. Sometime when I print out the result from server, it only contain partial information.

 

 

Really appreciate your help!

For your first question, it seems to me you are losing a socket connection
or timeout on the connection to server, check your network. For your  second
problem, it  may be  is related to  drop of socket from first question.
thx

Hi Amir,
To debug the partial return problem, I use WireShark to capture the traffic/packet on the network and find out the server does return the full content back to the client application, but for some reason, the client is not able to receive the complete content.
I am wondering if it relates to some buffer size that is not big enough for client to receive full returns.

Thanks,
Jan-fon

I would  recommend to use TCPMON utility that comes with Axis/c and
redirect the port so you can capture the payload.
