Sorry, I do not know if my question can be answer in this group, but I’m a newby in ws_discovery and in gsoap and I’m developing a tool to discover onvif ipcameras.
I have a IpfFastDomo onvif-compliant and when the camera sends a hello my application reaches a soap_fault in <d:Types> element:
My example code is very simple:
soap_init (&discovery);
soap_set_namespaces (&discovery, dpws_namespaces);
#ifdef DEBUG
soap_set_omode (&discovery, SOAP_C_UTFSTRING | SOAP_XML_INDENT);
#endif
/* initialize stack */
target_cache = dpws_create_tc (NULL);
if (dpws_init2 (&discovery_dpws, "0.0.0.0", target_cache) != SOAP_OK)
{
dpws_done (&discovery_dpws);
exit (0);
}
if (dpws_init_implicit_discovery2(&discovery_dpws, target_cache, &discovery, &discovery_hooks) != SOAP_OK)
{
dpws_done (&discovery_dpws);
exit (0);
}
//ponemos a leer
while (1)
{
err = dpws_discovery_process (&discovery, 1000);
if ((err != SOAP_EOF) && (err != SOAP_OK) && (err != SOAP_STOP))
{
soap_print_fault (&discovery, stderr);
}
}
The message from the IP camera is:

I do not know if the problem is that the <d:Types> is closed by a </wsd:Types>. I’m a bit confused with the namespaces. Maybe I must initialize some things in the soap struct?
Please, somebody can help me.

The problem is that ws4d-gsoaps ws-discovery implementation won't
support such a message.
The message is not valid because auf missing namespace declarations and
opening and closing tags that are different. One example is:
<d:Types>dn:NetworkVideoTransmitter</wsd:Types>
- the namespace prefixes dn and wsd are not defined
- opening and closing a tag with different prefixes is also not valid
(d:Types and wsd:Types)
So my first suggestion would be adding a workaround to ws4d-gsoap. But
there are so many failures in this message that it is better to ask the
manufacturer to fix the problems.

Elmar
