Client crashed while recieving response

Hi Dimuthu,

 

I am forwarding this mail, because there was a failure in delivery last time.

 

Thanks for the explanation. I understood the concept behind recreating an adb object at the client side. The only thing is, when i access the output message from the test client code, the client crashes

 

I checked with the tcpmon utility.  From the tcpmon, I am able to see the input message value and the output message field's values in the xml format. I have also attached the sample of the tcpmon.log.

 

So, i believe that my service is working. But why am i not able to print the value in the test client code? 

Issue No 1:

 

In my test client code (attached parse_client.c)

I am printing the value of a field in output message as below.

printf ("The address = %u\n",adb_pInterchange_get_pInterchange(parse_res,env)); This printf gives address as 0.

 

And the client code crashed at the next printf because this address is  0 and i am dereferencing it.

printf("The internal intref number = %u\n",     adb_INTERCHANGE_get_internal_intref_no(adb_pInterchange_get_pInterchange(parse_res,env),env)); // Crashed here

 

and the gdb output is below. If you can see _INTERCHANGE=0x0. It is strange.

0x000000000041257f in adb_INTERCHANGE_get_internal_intref_no (_INTERCHANGE=0x0, env=0x698340) at adb_INTERCHANGE.c:1811

Issue No 2:

 

The server still runs at this point. Now the second time i run the client, the server crashes. The gdb output for this is
