Hi Dumindu,

After several tries, I found out the segmentation error is because I updated
the libhello.so file but didn't restart the axis2_http_server.

It is not a permission issue.

Thanks.

Hi Yang and Dinesh,

I don't think that the axis2_http_server should seg fault on a
permissions issue. When I try to run the server without write
permissions for log file, it instead is written to the standard output.

I guess that this _might_ possibly be a bug. If you could please provide
more details on how the seg fault could be recreated.

Hi Dinesh,

Thank you very much for the reply. I just realized that I didn't run the
axis2_http_server with the correct permission, which caused the error I
mentioned above. and no log files been written because of the lack of
permission.

Now it runs fine. :)
Thanks.

I think it is possible, in order to determine what has happened in
your case we need some more details.

1. Are you sure about your service.xml ? What is the directory name
that you use to put your service?

2. Can you provide us your axis2.log , Please make sure to run server
in debug mode.

3. It would be great if you could send us gdb backtrace.

thanks,
Dinesh

[AXIS2C]: How to implement business logic in C++?

[Yingwei Yang]

Hi Group,

Because all my business logics are implemented in C++, so I am trying to
implement the hello_svc.c in C++.

Here is what I did:
1.  Added the explicit cast to cast void* to axis2_svc_skeleton_t*

   axis2_svc_skeleton_t *svc_skeleton = NULL;
   svc_skeleton = (axis2_svc_skeleton_t *)AXIS2_MALLOC(env->allocator,
   sizeof(axis2_svc_skeleton_t));

2. Added the
  #ifdef __cplusplus
  extern "C"
  {
  #endif

  and

  #ifdef __cplusplus
  }
  #endif

at the beginning and the end of the hello_svc.cpp file.

3. compile it using g++ (with the same argument as with gcc)

4. copy the libhello.so to the axis2c hello service.

5. Invoide the hello client

then I got the Segmentation fault at the "Invoke the handler context_handler
within the phase PostDispatch" phase.

what did I do wrong? is it possible to implement the service skeleton code
in C++?


Thanks!!!
