Subject Tuscany with BPEL
Date Mon, 22 Jun 2009 16:11:07 GMT
Greetings All,

I'm very new to tuscany and ODE, doing some experiments and disparately  
trying to get the right direction. I'm trying to manage the interaction  
between three Tuscany components with BPEL, the flow is like,
My BPEL component will receive the request from Client , on receiving the  
request it will invoke a Greeting Component after getting the response from  
greeting component , the BPEL will invoke another Hello component , my goal  
is to mix the response from these components and serve the same to the out  
side world.
While trying to do so, I'm getting an error /exception which I'm not able  
to crack. Please guide me to solve this issue,
