"How to get a list of process variable (name and value) from the processInstance
object?"

Implementing the ProcessEventListener and using the ProcessStartedEvent, I'd like to
get a list of process variables (name and value). Using the ProcessStatedevent, I get a
process instance (e.g., event.getProcessInstance()). But, I could not figure out an API to
get a list of variables. I casted the process instnace to the ContextInstance, but no
luck.
Any help will be appreicated.
Thanks,

Try with following code:
VariableScopeInstance variableScope = (VariableScopeInstance)
processInstance.getContextInstance(VariableScope.VARIABLE_SCOPE);
Map<String, Object> variables = variableScope.getVariables();
just make sure that process instance is of type org.jbpm.process.instance.ProcessInstance

Maciej,
Thank you very much! It worked nicely. Use of the
org.jbpm.process.instance.ProcessInstance was the key.

One more question on this topic...
Using the NodeInstance object, is it possible to retreive its (e.g., service task) input
parameters and output parameters (key and value)? There is a getVariable(String), but I
need to get all input and output parameters for monitoring purposes.
Thanks,
bwj

I figured it out myself:
===
org.jbpm.workflow.instance.node.WorkItemNodeInstance wn =
(org.jbpm.workflow.instance.node.WorkItemNodeInstance)event.getNodeInstance();
**if** (wn.getWorkItem() != *null) {
# for (String key : wiParamList.keySet()) {
System.out.println("param key: " + key.toString());
System.out.println("param value: " + wiParamList.get(key));
} } Map<String,Object> wiResultList = wn.getWorkItem().getResults();
if (wiResultList != null ) { for (String key : wiResultList.keySet()) {
System.out.println("result key: " + key.toString());
System.out.println("result value: " + wiResultList.get(key)); } }}
*
Map<String,Object> wiParamList = wn.getWorkItem().getParameters();
**if** (wiParamList != *null ) {*
