Handling dynamic binding

[Nariman Ammar]

Hello,

So far, I have used the model to generate processes with import statements.  If I want to generate processes which will bind with services dynamically based on the specifications indicated by the process. How can I do that?

Thanks

Hi,

for this you need to generate a different BPEL file that uses dynamic partnerlink changes, e.g. like described here (I found no English version quickly): http://www.se.uni-hannover.de/pages/de:tutorials_bpel_ode_dynamicinvoke

Hello,

The link you provided a case where we still hardcode the address for the concrete services. But in some cases, dynamic binding is done through lookup depending on results of a query (e.g. Xpath). I was more interested in such cases. My scenario is more like using an analysis pipeline to perform a task that collects data from several services based on a query submitted by the user.

Hi,

there is no problem to assemble this request dynamically, e.g. by having the endpoint variable and use a copy in the same or different <assign> activity to copy another URL into it.
