Subject dynamic headers
Date Tue, 22 Apr 2008 06:36:55 GMT
I've been looking at the page
http://ode.apache.org/headers-handling.htmlabout adding dynamic
headers to bpel, but I can't quite get it to work.

My BPEL is below. I want to assign a header to Variable1 before I invoke. I
call it "someHeader". What else do I need in my BPEL code to get this to
work?

Thanks,

Mark
