Hello,
<br/><br/>We are trying to dynamically change the endpoint address of a PartnerLink in a BPEL file, following
<br/>the ideas in: <a href="http://www.oracle.com/technetwork/articles/carey-090553.html" target="_top" rel="nofollow" link="external">http://www.oracle.com/technetwork/articles/carey-090553.html</a> which describes
<br/>the usage of a EndpointReference variable from the <a href="http://schemas.xmlsoap.org/ws/2003/03/addressing" target="_top" rel="nofollow" link="external">http://schemas.xmlsoap.org/ws/2003/03/addressing</a> Schema.
<br/><br/>We designed a simple BPEL process to test the assignment of an EndpointReference variable containing the endpoint URL to a PartnetLinkReference. However, we get an exception when doing this.
<br/>The assignment is created by the PetalsStudio visual editor. The resulting BPEL process is attached <a href="http://forum.petalslink.com/file/n3528646/NewProcess.bpel" target="_top">NewProcess.bpel</a><br/><br/>We tried the following:
<br/>1) Assigning the EndpointReference variable to the addresser partnerLink = ERROR
<br/>2) Deleting the assignment = OK, the addresser partnerLink is called without errors
<br/>3) Assigning the EndpointReference variable to a test partnerLink which is not used in the orchestration = ERROR
<br/><br/>Explaining a little more the errors:
<br/><br/>During the first call, we get the following exception in the SOAP Response in case 1:
<br/><pre>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

</pre><br/>During the following calls, we get only
<br/>[Root]-SEVERE 2011-11-22 16:29:55,889 No matching activity were found for given message null
<br/><br/>in Petals log, and there is no response to the client, for both cases 1 and 3.
<br/><br/><br/>I was wondering if this is the correct way to dynamically assign the endpoint URL to a partnerLink. Could you provide some help with that?
<br/><br/>Thanks very much.
