[OpenSIPS-Users] tomcat external app listening to OpenSIPS events

HI,

I really appreciate you taking the time!!

yes OpenSIPS is connecting to Tomcat, the problem I see (I think) is when the event is being raised OpenSIPS is NOT sending the complete URI. Tomcat server returns an error of 404.
the Tomcat logs seem to indicate  OpenSIPS is only be sending 192.168.3.132:8080 -> when it should be sending 192.168.3.132:8080/ccurbiz/xmlrpc

Thanks!!
Juls

Hi Julian,

So, you say OpenSIPS is actually connecting via HTTP to tomcat in order to deliver the event, right ?
