How to start a process with variable from JBPM-Console

wawan_beta Jun 1, 2010 9:48 AM

I want to start the process with user forms and I need to declare global variables so as to continue working with them, how to do this?

I deploy the business archive using an Ant script then run a process instance via the jBPM console.

example:

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

<mail g="387,32,179,80" language="juel" name="send email">
<to addresses=${email}/>
   <subject>${subject}</subject>
<text>Hallo ${userName}</text>
      <transition g="-76,-18" name="to EndEvent_1" to="EndEvent_1"/>
</mail>

<end g="676,38,48,48" name="EndEvent_1"/>

</process>

test.ftl

<h3>Hallo</h3>
Your Name: <input type="text" name="userName"/><br/>

<hr>

</form></body></html>

use form attribute of start activity, exactly the same as for task node.

<start form="start_form.ftl" name="start1">

Once you have that console will open a window with defined form prior to starting the process.

thanks for the reply, this works
I have one more question, how to create a variable Date?

i have found this code
<input type="text" name="dTEMP"/><br/>
<#assign bTermin = "${dTEMP}"?datetime("yyyy-MM-dd hh:mm a")>

but it doesn't work...

I am afraid that everything that is transferred from the start form to the process instance will be of type String.

What I could suggest you to do is to use event listeners attached to an end event of start activity to do the required transformation for the variables.

can you please show me an example transformation of the variables
and what is end event of start activity?

<start name="StartEvent_1" form="org/bew/prozess/test.ftl">
     <on event="???????">
          <event-listener class="org.bew.prozess.Convertor"/>
      </on>
     <transition to="ask name"/>
</start>

You can use something like that (note this is very simple just to illustrate):

public void notify(EventListenerExecution execution) {

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    try {
      //fist to the conversion
      Date date = sdf.parse((String) execution.getVariable("date"));

      // next replace string with newly created Date instance
      execution.setVariable("date", date);
    } catch (ParseException e) {
      e.printStackTrace();
    }
    
  }

on you definition you can use end event:

<start name="StartEvent_1" form="org/bew/prozess/test.ftl">
      <on event="end">
          <event-listener  class="org.bew.prozess.Convertor"/>
      </on>
      <transition to="ask name"/>
</start>

That's it.
