    jBPM 5 - How to Pass parameters in a WorkItem BPMN2 file

    scurvo Newbie

      Hi all again

       

      I am trying to create a work item that receives certain parameters, and does stuff depending on them.

      Through the examples i created this BPMN2 file:

       

      <?xml version="1.0" encoding="UTF-8"?>

      <definitions id="Definition"

                   targetNamespace="http://www.example.org/MinimalExample"

                   typeLanguage="http://www.java.com/javaTypes"

                   expressionLanguage="http://www.mvel.org/2.0"

                   xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"

                   xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"

                   xs:schemaLocation="http://www.omg.org/spec/BPMN/20100524/MODEL BPMN20.xsd"

                   xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI"

                   xmlns:dc="http://www.omg.org/spec/DD/20100524/DC"

                   xmlns:di="http://www.omg.org/spec/DD/20100524/DI"

                   xmlns:tns="http://www.jboss.org/drools">

       

          <itemDefinition id="_sItem" structureRef="java.lang.String"/>

          <itemDefinition id="_int" structureRef="java.lang.Integer"/>

       

          <process id="TestWI" name="Test the WI" >

       

              <!-- process variables -->

              <property id="data_provider_ID" itemSubjectRef="_sItem"/>

              <property id="data_source_ID" itemSubjectRef="_sItem"/>

              <property id="source_url" itemSubjectRef="_sItem"/>

              <property id="source_set" itemSubjectRef="_sItem"/>

              <property id="metadata_format" itemSubjectRef="_sItem"/>

              <property id="record_count" itemSubjectRef="_int"/>

       

              <startEvent id="_1" name="StartProcess"/>

              <sequenceFlow sourceRef="_1" targetRef="_2"/>

              <task id="_2" name="Harvest" tns:taskName="Harvest" >

                  <ioSpecification>

                      <dataInput id="dpID" name="DATA_PROVIDER_ID" />

                      <dataInput id="dsID" name="DATA_SOURCE_ID" />

                      <dataInput id="src_url" name="SOURCE_URL" />

                      <dataInput id="src_set" name="SOURCE_SET" />

                      <dataInput id="mtd_format" name="METADATA_FORMAT" />

                      <dataInput id="rcrd_count" name="RECORD_COUNT" />

                      <inputSet>

                          <dataInputRefs>dpID</dataInputRefs>

                          <dataInputRefs>dsID</dataInputRefs>

                  </dataInputAssociation>

                  <dataInputAssociation>

                      <sourceRef>data_source_ID</sourceRef>

                      <targetRef>dsID</targetRef>

                  </dataInputAssociation>

                  <dataInputAssociation>

                      <sourceRef>source_url</sourceRef>

                      <targetRef>src_url</targetRef>

                  </dataInputAssociation>

                  <dataInputAssociation>

                      <sourceRef>source_set</sourceRef>

                      <targetRef>src_set</targetRef>

                  </dataInputAssociation>

                  <dataInputAssociation>

                      <sourceRef>metadata_format</sourceRef>

                      <targetRef>mtd_format</targetRef>

                  </dataInputAssociation>

                  <dataInputAssociation>

                      <sourceRef>record_count</sourceRef>

                      <targetRef>rcrd_count</targetRef>

                  </dataInputAssociation>

              </task>

              <sequenceFlow sourceRef="_2" targetRef="_3"/>

              <endEvent id="_3" name="EndProcess">

                  <terminateEventDefinition/>

              </endEvent>

          </process>

       

      </definitions>

       

       

      I was able with this to get the parameters i defined in the corresponding work item's handler.

      Although i made it now that i want to have multiple work items like this on a single process i have a para meter problem .

      Is it possible to define my parameters right on the bpmn2 file?

      If not, is there a way of getting the ID of the task of a workItem (i wana get that <task id="_2"...)?
