Subject Re: How to detect when a web service is inactive
Date Wed, 29 Oct 2008 16:57:43 GMT
A while ago we wrote a "ping" module for Axis2 to check whether a service 
is alive (obviously that only works for services in axis2). The basic idea 
was to have the service get the chance to say "yep all's cool I'm ok" by 
delivering a message all the way to service (which can check for needed 
resources etc.).

Otherwise its like an IP ping which doesn't say much about whether the 
machine's really up and running.
