BPEL Invoke reponse issue

Question

Hi,
I'm pretty new to BPEL. I'm using netbeans IDE.
I'm having an issue with invoke.
My BPEL is pretty simple process, it receives input which is a city name
and then invokes a webservice from a mileage system which returns latitude/longitude as as string. BPEL process takes the output from the invoke and send it to the client.
Invoke seems to be working fine, BPEL is taking the input from client and invoking the webservice passing the city name. By looking at the logs i can tell that it is calling webservice and it is finding the lat/long, but it is not returning the value back to BPEL. I have an output variable to receive the result which is always coming back empty.
I must be doing something wrong (something simple). Please help me.
Thanks
Praveen

Answer 1

Yes, I'm assigning results from invoke to process output.
Here I'm posting my BPEL that you can look at and let me know, If I'm doing something wrong.
Thanks for your reply and help.
