RuntimeException in handler method, transition to DOES_NOT_E

deepuin9 Nov 20, 2007 5:02 AM

Can anyone help me in understanding the below exception. I am using
jboss-4.0.5.GA, jbpm-bpel-1.1.Beta3.
I am posting the bpel and wsdl's too.
Thanks for your help in advance.

1. Re: RuntimeException in handler method, transition to DOES_N

Hi, try to change the query statements for XPATH statements. Like this:
Change this:
<copy> <from part="length" variable="ac3ipRequest"/> <to part="calarea" query="/area:calculateArea/in0" variable="calculateAreaRequest"/> </copy>

For this:
<copy> <from part="length" variable="ac3ipRequest"/> <to>$calculateAreaRequest.calarea/area:calculateArea/in0</to> </copy>

And one question.
What are you using for test the BPEL process?

Thanks for the solution dude. I will try it out tomorrow morning as its time for me to sleep. :)

About your question, If you meant validation of bpel process then, sorry mate I dont know any tool. :(. i have eclipse designer plug-in in my eclipse environment which checks the bpel process for well-formateness.

agusgr Nov 20, 2007 1:15 PM (in response to deepuin9)

I meant consumtion of the process. What kind of client do you use??
An axis client, a generic soap client, a visual basic client...
Looking in the logs I see the excepcion in the soap request handler, so maybe a problem with the soap request message of your client. Is only a theory, :).
See you tomorrow, :-P

deepuin9 Nov 21, 2007 2:53 AM (in response to deepuin9)
I use "soapUI" http://www.soapui.org/.

Hey its working now, your suggestion helped me to think little out of box. :) Thank you very much.

Here is the change i have made to make it work.

Changed the below code:
<copy> <from part="length" variable="ac3ipRequest"/> <to part="calarea" query="/area:calculateArea/in0" variable="calculateAreaRequest"/> </copy>

TO:
<copy> <from part="breadth" variable="ac3ipRequest"/> <to part="calarea" query="/calarea/in1" variable="calculateAreaRequest"/> </copy>

Did the same for all the xpath queries.

Thanks
Sandeep.
