Re: Using MEX Interceptors for new instance invocations

[Denis Weerasiri <dd...@gmail.com>]

Hi Karthick,
Sorry to bother you again. I'm trying to suspend a instance at the MEX
interceptor. So to use the DebuggerSupport class, I need to get the
reference of the current ODEServer or the BPELServerImpl. Is it possible to
get those reference through the InterceptorEvent object. Or do I have to use
the Instance Management service to do that.?

Best Regards,

Yep. In trunk the API is little bit different.
