create and use context's

hello users,

in java i am able to use the different context's,
like service context and playing around with the
different scope's.

i can see, that the adb_svc_skel_<service>_invoke
method passes a message context (axis2_msg_ctx_t *msg_ctx).

when i try to get the service context id, it's NULL.

tmp_a_str = axis2_msg_ctx_get_svc_ctx_id(msg_ctx, env);
printf("Id : %s\n", tmp_a_str);
out -> Id : NULL

when i try to get the service context from the message context,
i get a message context object, but it seems not to work.

i think i have to register the context i want to use in
adb_svc_skel_<service>_init, but i don't know how to do this.

who can explain ?
