Hi Tammo, indeed the getInput() is causing the NPE. (no Inputpart /-message was set and could be parsed from the WSDL) sadly I don't have access to an JIRA.

Could you please file a JIRA? If you have a debugger running, it would be valuable to know, which field causes the NPE. My guess is that getInput().getMessage() returns null.

The Apache ODE engine throws exception if i try to invoke webservice without parameter. Because there is no InputMessage to the WebService. As far as I know is there no need of input message (minOccurs="0" of InputOperationMessage in W3C def). A webservice with no input message should be supported, but as workaround I’m using a empty messagepart with input message link. It is working, but the WSDL file is not as clean as I thought it should be. Anyway, is the ODE engine working as intended, and do I missing something? best regards, dominic <!—w3c tBindingOperation –> <xs:complexType name="tBindingOperation"> <xs:complexContent> <xs:extension base="wsdl:tExtensibleDocumented"> <xs:sequence> <xs:element name="input" type="wsdl:tBindingOperationMessage" minOccurs="0"/> <xs:element name="output" type="wsdl:tBindingOperationMessage" minOccurs="0"/> <xs:element name="fault" type="wsdl:tBindingOperationFault" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="name" type="xs:NCName" use="required"/> </xs:extension> </xs:complexContent> </xs:complexType> <!—used WSDL def–> <wsdl:types> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
