Subject Multiple svc_client
Date Mon, 20 Sep 2010 20:19:55 GMT
Ciao C-user

I have a problem: I'm writing a client that sends soap messages with axis2. I need send messages
to different addresses based on the message type.

So in my client application I've created an axis2c environment  with axutil_env_create_all
and multiple axis2 option with
axis2_options_create, one for each address. I've created and attach an end point reference
with axis2_endpoint_ref_create and
axis2_options_set_to and, finally I've created a service client with axis2_svc_client_create
and attached to the option with

When is time to send a message I choose the correct svc_client and send a message with axis2_svc_client_send_receive.
I reuse the svc_client
for every message (so i create the various svc_client objects at the beginning of the program
and use them when needed).

If I use only one svc_client all is working fine but as soon as I started to send messages
to more than one svc_client after few messages the
program crashes trying to free something inside axis2_svc_client_send_receive.

Is it not possible to use different svc_client object at the same time? I had to free and
create a svc_client with the correct address for
every request?

Here there is the backtrace:
