Subject Re: How to add an activity breakpoint to an instance
Date Sat, 18 Jul 2009 02:01:46 GMT
Hi Denis,
Is there anyway that we can set global breakpoint for a process. If that is
there we can first set global breakpoint for processes and when we invoke
the process using sample input the created instance must come to that
breakpoint and suspend until user resume it from that point. I am not sure
about the correct way to do it, but I think BPEL debugging must be same as
normal debugging we done using Java IDEs or etc.. Here are some documents
from Open-ESB.

Testing And Debugging BPEL Processes:
http://wiki.open-esb.java.net/Wiki.jsp?page=TestingAndDebuggingBPELProcesses
BPEL Debugger Tutorial:
http://wiki.open-esb.java.net/Wiki.jsp?page=BPELDebuggerTutorial

Can you have look and propose a better way for our we based thing. Because I
think that this must be same as normal debugging. I'll study Open ESB thing
little bit and let you know my ideas ASAP.

thanks
Milinda
