First, kudos to the entire team, Activiti's been a treat to learn (even for a Java newbie).Issue: I've had surprising success with fairly complex Activiti workflows, but have failed to integrate Activiti into our async python/php infrastructure.Use case - Amazon Mechanical Turk process: - intiate p

You can just use varaibles in you script. So if you have a process-variable with name "myProcessvar", it will be available in the script-context as myProcessVar. The business-key is curently not exposed in scripts. A workaround (delegateExecution.getBusinessKey() will be available in activiti 5.6) could be storing the businessKey as variable:

- Use a execution/task listener right before the script-task, using an expression, eg:


<extensionElements>
      <activiti:executionListener expression="${execution.setVariable('theKey', execution.getBusinessKey()}" event="take" />
    </extensionElements>

- In scriptTask, business-key is available under variable theKey

About the REST-API. Not all java-api calls are available through rest. So getting al tasks for a processInstanceID is not possible… You'll have to extend the activiti-rest or write your own servlet/rest-endpoint in the java-app that calls the Activiti java-API I'm affraid…
