Hi Luis, I looked in to the attached bpel. First I looked into the deploy.xml. It contains no elements like <provide/> <invoke/> elements. Every partner link used with a <receive /> activity must be matched with a <provide /> element, and every partnerLink used in an <invoke /> activity must be matched with an <invoke /> element in deploy.xml. Without a deploy.xml, a BPEL engine cannot figure the concrete level details of the partner services. In the deploy.xml, the <service /> element determines the concrete level details of all the partner services that interacts with the BPEL process.
eg - <?xml version="1.0" encoding="UTF-8"?> <deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03"; xmlns:FunctionProcess.bpel="http://FunctionProcess.bpel"; xmlns:FunctionProcessService.wsdl="http://FunctionProcessService.wsdl"; xmlns:AdderService.wsdl="http://AdderService.wsdl"; xmlns:MultiplierService.wsdl="http://MultiplierService.wsdl"; xmlns:SquareService.wsdl="http://SquareService.wsdl";> <process name="FunctionProcess.bpel:FunctionProcess"> <process-events generate="all"/> <provide partnerLink="FunctionProcessPartnerLink"> <service name="FunctionProcessService.wsdl:FunctionProcessServiceService" port="FunctionProcessServicePort"/> </provide> <invoke partnerLink="SquarePartnerLink"> <service name="SquareService.wsdl:SquareService" port="SquareServiceSOAP11port_http"/> </invoke> </process> </deploy> So the http://services.sapo.pt/Metadata/Contract/ADSL?culture=PT also should be stored locally. There may be other issues as well.
