Re: Client crashed while recieving response

Hi Sathya,

Since your service is running fine, the error should be in the deserialize logic. And there were some bugs in the deserialize logic. But I think in the latest axis2/java source svn, these bugs are fixed.  (At least current test cases are working fine) 

And AFIK the second problem (The server crash) was also  a known one, not keeping copy of strings inside adb objects. That is also fixed in the latest svn.

Thanks

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.

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