[bpel-dev] Re: question about deployment to Apache ODE

[sam wang <samwzm@xxxxxxxxx>]

thanks for the quick reply and help, Michal!

As for the namespace problem, I think it is a big and common problem. For example, we want to make
a simple BPEL, there are two web services--ws1 and ws2. ws1 is invoked first and then ws2 is
invoked. In order to make this simple BPEL work, ws1's output must be compatible with ws2's input.
However, usually ws1's namespace is different with ws2's, there is no way to feed ws1's output
directly into ws2's input. As I know, it's a really painful process to configure namespace when I
try to use ActiveBPEL designer. Taverna(http://taverna.sourceforge.net/) seems solve this problem
very well. However, it's not a BPEL designer. It uses XScufl workflow language. So I guess
namespace is a common problem for BPEL process, and I don't know how to solve this problem. Does
there anyone know how Eclipse BPEL designer handles this problem?

Thanks!
Sammy
