Subject AW: BPEL process with more than one operations
Date Tue, 24 Jun 2008 08:27:50 GMT
So I just found a solution by myself, but I'm interested to hear if someone
has a better idea:

I've replaced the <flow></flow> block by a <pick></pick> block which
listening for the incoming messages:

<pick createInstance="yes">
	<onMessage operation="login" partnerLink="client" ...>
	...activities for operation login
	<onMessage operation="process" partnerLink="client" ...>
	...activities for operation process

This just solves my problem. Btw: if someone has a similar problem, one
won't need an <receive/> in the activities section anymore, because this is
already done by the <pick> in combination with <onMessage>.
