Hi everybody.... I'd like you to help me out a little bit. I'm building a test BPEL process which invoke a REST webservice. The process it's quite simple, it receive an input parameter which is assigned to the webservice input message and it response is assigned to the BPEL process output message. The invocation is done using a WSDL file enriched with ODE WSDL1.1 Extensions for REST. You can check the BPEL file in [1] and the "RESTful" WSDL in [2]. The REST webservice reply a XML file describing a simple client entity (as shown in [3]). The invocation is done and it gets the response correctly. This is the server log for that event:
23:53:36,948 DEBUG [ExternalService] Executing HTTP Request : GET http://localhost:8182/TiendaOnline/clientes/12345678 23:53:36,948 DEBUG [ExternalService] HTTP Request Details: GET http://localhost:8182/TiendaOnline/clientes/12345678 Request Headers: Accept: application/xml 23:53:36,957 DEBUG [ExternalService] Received response for MEX hqejbhcnphr7r4u5i67n4p 23:53:36,958 DEBUG [ExternalService] HTTP Response Details: GET http://localhost:8182/TiendaOnline/clientes/12345678 Status-Line: HTTP/1.1 200 OK Response Headers: Date: Tue, 13 Nov 2012 02:53:36 GMT Accept-Ranges: bytes Server: Restlet-Framework/2.0.13 Vary: Accept-Charset, Accept-Encoding, Accept-Language, Accept Content-Length: 169 Content-Type: application/xml; charset=UTF-8 Response Entity: <?xml version="1.0"?><tns:CLIENTE xmlns:tns="http://cliente.tiendaonline.restws";><tns:idCliente>12345678</tns:idCliente><tns:descuento>0.56</tns:descuento></tns:CLIENTE> After the XML is recived, extra elements are added, as shown in the server log 23:53:36,990 DEBUG [MessageDAOImpl] setData null <?xml version="1.0" encoding="UTF-8"?> <message><CLIENTE><tns:CLIENTE xmlns:tns="http://cliente.tiendaonline.restws";><tns:idCliente>12345678</tns:idCliente><tns:descuento>0.56</tns:descuento></tns:CLIENTE></CLIENTE></message> The problem comes when the webservice response is assigned to bpel process tns:result variable...Ii get this error log 23:53:37,129 DEBUG [ASSIGN] Evaluating FROM expression "{VarRef {Variable __PROCESS_SCOPE:CompraOnline-restfull.RWS_ClientePLResponse:OMessageVarType#14({http://cliente.tiendaonline.restws}clienteResponse)}.CLIENTE{OXPath10Expression descuento}}". 23:53:37,130 INFO [ASSIGN] Assignment Fault: {http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure,lineNo=162,faultExplanation=No results for expression: {OXPath10Expression descuento} I understand that this mean that that the XPath expression failed to get a result, and as for the ode-user mailist thread in [4] I know that this must be a xmlns problem, but I don't know what I'm doing wrong. Please, if somebody can give a hint of what I should do, it would be grate.
