JBPM 3.2 - websale example - Where are the process variables

ygiriyap Mar 30, 2007 10:33 AM

Hi ...

In JBPM 3.1.4 websale example,I see the definitions of the process variables in the processdefinition.xml file like below ...

<start-state name="create new web sale order">
 <task swimlane="buyer">
 <controller>
 <variable name="item"/>
 <variable name="quantity"/>
 <variable name="address"/>
 </controller>
 </task>
 <transition to="evaluate web order" />
 </start-state>

But,in JBPM 3.2 websale example,I dont see the definitions of the process variables in the processdefinition.xml file.
They are being used in the forms(files like form.create.xhtml) and are also in the DB table jbpm_variableinstance.

My querie related to JBPM 3.2 ...
Where are these variables defined ? Where all can I define the variables?

Please let me know.Thanks in advance.

Variables can be defined anywhere.

Actually, from the pdl docs, it looks like "item", "quantity" and "address" will be created as task instance variables if there are not process variables of the same name. Can anyone confirm this?

Is there a way to declare the process variables at the beginning of the process definition in the PDL? Otherwise, they would have to be created using code in an action, correct?

Hey ... Thanks for the replies.
Got it.

In the user guide its mentioned that ...
10.2. Variable lifetime Variables do not have to be declared in the process archive. At runtime, you can just put any java object in the variables. If that variable was not present, it will be created. Just the same as with a plain java.util.Map.

Thank you.
