Hello,

the error message is printed in case of an invalid xml document.

Can you edit modules/xcap_server/xcap_misc.c and add inside function:

int xcaps_check_doc_validity(str *doc)

the log:

LM_ERR("xmld document is: [[%.*s]]\n", doc->len, doc->s);

before the line with:

docxml = xmlParseMemory(doc->s, doc->len);

Re-compile and re-install. Then run a test and send here the output of this line.

Cheers, Daniel

I am trying to set up XCAP support for SIP SIMPLE, and using jitsi as the sample client. The kamailio database was previously configured using ODBC and kamailio-4.1.3 and was apparently working correctly. I was following the guide at http://nil.uniza.sk/instant-messaging/simple/configuring-xcap-support-im-and... as well as the standard documentation at http://kamailio.org/docs/modules/4.1.x/modules/xcap_server.html . However, the rls support is currently disabled. When I use jitsi to connect, and add one contact to the empty contact list, I see the database being populated (mysql backend):

As far as I can see, both XML documents are well formed.

However, if I shutdown and then restart jitsi, I see (with wireshark) that the server returned a 500 Server Error when trying to fetch resource-lists . At the same time, the following appears on the log:

What can I do to solve this issue. This is preventing contacts from being retrieved or added once the first contact is stored.

My event-route looks like this (WITH_XCAPSRV is defined elsewhere in the configuration):

#!ifdef WITH_XHTTP event_route[xhttp:request] { #!ifdef WITH_XHTTP_RPC $var(xhttp_rpc_root) = $(hu{s.substr,0,9}); if ($var(xhttp_rpc_root) == "/http_rpc") { dispatch_xhttp_rpc(); } #!endif #!ifdef WITH_XHTTP_PI $var(xhttp_rpc_root) = $(hu{s.substr,0,8}); if ($var(xhttp_rpc_root) == "/http_pi") { dispatch_xhttp_pi(); } #!endif #!ifdef WITH_XCAPSRV if ($hu =~ "^/xcap-root/") { route(XCAPSRV); } #!endif
