Error description
The web service External Service discovery generates an incorrect interface if the discovered WSDL specifies a parameter of a complex type with exactly one property that is a list (array wrapper) and the type of the list property is specified with a "ref" attribute. The issue that occurs only happens when using Web based Process Designer, aka WebPD. The following example is of a WSDL port type that causes an incorrect discovery: <?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions name="Pets" targetNamespace="http://bpm.ibm.com/Pets" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://bpm.ibm.com/Pets" xmlns:ns0="http://bpm.ibm.com/Pets/Schema.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"> <wsdl:types> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://bpm.ibm.com/Pets/Schema.xsd" xmlns="http://bpm.ibm.com/Pets/Schema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="pet"> <xs:complexType> <xs:sequence> <xs:element name="petName" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="petList"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" minOccurs="0" ref="ns0:pet" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="GetPets"> <xs:complexType> <xs:sequence> <xs:element name="petName" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="GetPetsResponse"> <xs:complexType> <xs:sequence> <xs:element ref="ns0:petList" /> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </wsdl:types> <wsdl:message name="GetPets"> <wsdl:part name="part1" element="ns0:GetPets" /> </wsdl:message> <wsdl:message name="GetPetsResponse"> <wsdl:part name="part1" element="ns0:GetPetsResponse" /> </wsdl:message> <wsdl:portType name="PetsPortType"> <wsdl:operation name="GetPets"> <wsdl:input message="tns:GetPets" /> <wsdl:output message="tns:GetPetsResponse" /> </wsdl:operation> </wsdl:portType> </wsdl:definitions> At run time you will see an exception stack similar to: Caused by: java.lang.NullPointerException at com.ibm.bpm.ws.jaxws.connector.util.JAXWSHelper.getXMLTypeDesc(J AXWSHelper.java:162) at com.ibm.bpm.ws.jaxws.serialize.DocLiteralMessage.demarshalRespon se(DocLiteralMessage.java:153) at com.ibm.bpm.ws.jaxws.connector.SOAPConnector.processDocLiteralOp eration(SOAPConnector.java:644) at com.ibm.bpm.ws.jaxws.connector.SOAPConnector.createServiceClient (SOAPConnector.java:493) at com.ibm.bpm.ws.jaxws.connector.SOAPConnector.execute(SOAPConnect or.java:193) ... 106 more PRODUCTS AFFECTED IBM Business Process Manager (BPM) Express IBM BPM Standard IBM BPM Advanced IBM Business Automation Workflow
