All processInstance variables into a java activity ?

[newbeewan]

Hi,

I looking for something to permit the injection of all variables as method arg in java activity in jbpm 4.3...

My java activity needs all the current process variables to generate a document... is it possible to describe that ?

My java class accepte a java.util.Map, but I don't know how to put it in <arg> tag...

<java g="77,90,157,40" name="generateMyDocument" expr="#{pdfDocumentGenerator}"
  method="generate" var="userDocumentPath"
  >
  <arg><string value="myDocumentTemplateURL"/></arg>
<arg><object expr="#{?(here something to get the map containing process instance variables)}"/></arg>

  </java>

did you consider implementing ExternalActivityBehaviour and using the <custom /> tag, in the execute() method you can access whatever variable you want:

[...]
public void execute(ActivityExecution execution) {
   Object variable = execution.getVariable("variablename");
}
[...]

Effectivelly, it does the job..

I prefere to use ActivityBehaviour in place of ExternalActivityBehaviour (simpler to implement no "signal" method).

An other way I found is to create an eventlistener to listen the stratup of that activity to populate data before java execution...
