For instance, two strings? What would the interface xml look like? For instance, this works when MyMethod just takes one string as an input parameter: public String MyMethod(String inputString) <itemDefinition id="_4_InMessageType" structureRef="java.lang.String" />   <message id="_4_InMessage" itemRef="_4_InMessageType" />   <interface id="_4_ServiceInterface" name="com.test.MyService">     <operation id="_4_ServiceOperation" name="MyMethod">       <inMessageRef>_4_InMessage</inMessageRef>     </operation>   </interface> But how would you define the interface if it takes two strings as input? public String MyMethod(String inputString1, String inputString2) I tried something like this without success... <itemDefinition id="_4_InMessageType" structureRef="java.lang.String" />   <message id="_4_InMessage" itemRef="_4_InMessageType" />   <message id="_4_InMessage2" itemRef="_4_InMessageType" /> <interface id="_4_ServiceInterface" name="com.test.MyService">      <operation id="_4_ServiceOperation" name="MyMethod">       <inMessageRef>_4_InMessage</inMessageRef>       <inMessageRef>_4_InMessage2</inMessageRef>     </operation>   </interface> with the service task being <serviceTask id="_4" name="MyService" operationRef="_4_ServiceOperation" implementation="Other" >       <ioSpecification>         <dataInput id="_4_param1Ref" name="Parameter" />         <dataInput id="_4_param2Ref" name="Parameter" />         <dataOutput id="_4_result" name="Result" />         <inputSet>           <dataInputRefs>_4_param1Ref</dataInputRefs>           <dataInputRefs>_4_param2Ref</dataInputRefs>         </inputSet>         <outputSet>           <dataOutputRefs>_4_result</dataOutputRefs>         </outputSet>       </ioSpecification>       <dataInputAssociation>         <sourceRef>ipAddress</sourceRef>         <targetRef>_4_param1Ref</targetRef>       </dataInputAssociation>       <dataInputAssociation>          <sourceRef>serialInterface</sourceRef>          <targetRef>_4_param2Ref</targetRef>       </dataInputAssociation>       <dataOutputAssociation>         <sourceRef>_4_result</sourceRef>         <targetRef>thisResult</targetRef>       </dataOutputAssociation>     </serviceTask> thanks... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/639918#639918] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
