    Beginner Question: How to pass process variables to a Java Task?

    Paul Mueller Newbie



      I am new to jBPM, and i currently do not understand how to pass process variables into a Java Task.

      To start the java task i have this code fragment:


      <java name="MyMethod" method="testMethod" var="result">
                    <string value="#{test}"/>     


      The java method:


      public String testMethod( String testIn )
        return testIn+"_result";


      To start the process i have this:


      Map<String,Object> variables = new HashMap<String,Object>();
      variables.put("test", "a test text");
      pi = executionService.startProcessInstanceByKey("MyProcess", variables );


      As a result i got "#{test}" and not "a test text". So what i am doing wrong?

      And what is the best practice to pass process variables to a java task?


      Thanks for help!
