I need to add elements to the soap envelope header before calling a
web service.
The api seems to support specific elements in the soap envelope header
such as AXIS2_MSG_INFO_HEADERS_SET_TO.
Q1.
Having cloned the sample code eg math, what is the best way to add
elements to the soap envelope header?
Please have a look at the addr_echo sample.
After the following line you can access the SOAP envelope throuhg the
message context and set the headers.
msg_ctx = AXIS2_MEP_CLIENT_PREPARE_SOAP_ENVELOPE(mep_client, &env, node);
you can do the following:
axis2_soap_envelope_t *envelope =
AXIS2_MSG_CTX_GET_SOAP_ENVELOPE(msg_ctx, &env);
Then use the API of soap_envelope to get the soap_header and use the
soap_header API. Please have a look at the header files for the API.
Q2
At what point has the SOAP envelope been create so that I could get
the envelope and add elements to it?
When you use the API of call, you have more control to manupulate the
SOAP stuff, and the soap envelope is crated after the call to
AXIS2_MEP_CLIENT_PREPARE_SOAP_ENVELOPE
Q3
Does the api just create stuff as it needs anyway and I could do
Please use the addr_echo sample as I mentioned earlier if you want more
control.
P.S. In line with the altest Axis2 Java API, we plan to provide the
operation client and service client APIs very soon.
We hope your life would be much easy once those APIs are provided.
Thanks,

Unravelling the sample code
-------------------------------------------------------------------------------------------------------------------------------
stub =
axis2_stub_create_with_endpoint_uri_and_client_home(&env, address,
client_home);
AXIS2_STUB_SET_TRANSPORT_INFO(stub, &env, AXIS2_TRANSPORT_HTTP,
AXIS2_TRANSPORT_HTTP, AXIS2_FALSE);
call = AXIS2_STUB_GET_CALL_OBJ(stub, env);
ret_node = AXIS2_CALL_INVOKE_BLOCKING_WITH_OM(call, env,
"CreateInstanceRq", node);
This is format of the request I am trying to send. (ASAP/wfxml protocol)
