Calling simple WSDL service with BPEL

I'm trying to create a simple BPEL process in Sonic Workbench, that will call a WSDL webservice I created. I am getting this error message after running the process:

Cannot send message to anonymous endpoint for "{http://informationservice.project.com/}InformationService" in partnerLink information

I have no idea what this error message means and googling doesn't help.

Thanks

Edit: BPEL Code:

I don't know Sonic, but from the error message I'd guess that the partnerlinks partner role is not associated with a partner EPR. In BPEL a partner link has a myRole part (which is the interface a partner expects from me to be implemented and to be provided for the partner's use) and the partnerRole, which is linked to the portType the partner implements and that provides the operation your BPEL process wants to invoke. All this stuff is defined in BPEL and WSDL. For the concrete binding of endpoints, BPEL engines use deployment descriptors which define the mapping of an EPR (either a concrete endpoint, e.g. an URL, or an indirect endpoint (e.g. identifying a port which holds the EPR) to the partner role. I assume this mapping is missing in your case.

Edit: In your code snippet, the initializePartnerRole attribute of the partnerlink is set to no, which means the BPEL processor MUST NOT initialize the EPR of the partner role before it is first utilized. This is probably causing your problem. You can set it to yesto force the engine to initialize the EPR or omit the attribute to leave the decision up to the engine. See section 6.2 in the BPEL 2.0 spec for further details.
