The PUBLISH request works when using the following configurations(no XCAP):

loadmodule "sl.so"
loadmodule "mysql.so"
loadmodule "presence.so"
loadmodule "presence_xml.so"
modparam("presence_xml", "db_url", "mysql://openser:openserrw@localhost:3306/openser")
modparam("presence_xml", "force_active", 1)
modparam("presence_xml", "pidf_manipulation", 1)

It doesn't if starting XCAP by updating these, the server can run properly, but cann't handle PUBLISH.

loadmodule "xcap_client.so"
modparam("presence_xml", "xcap_table", "xcap_xml")
modparam("presence_xml", "force_active", 0)
modparam("presence_xml", "xcap_server", "localhost:5065")

I don't know whether or not the xcap_server is set correct. There is no external XCAP server integrated. BTW, I know presence support XCAP function, does it means this module has already included a XCAP server?

Thank You!
