Hi,

you have to insert facts (objects) into the working memory of the session in order to evaluate them. This can be done in Java code or in a script task. See the example:

ksession.insert(fact);
WorkflowProcessInstance wpi = (WorkflowProcessInstance) ksession.startProcess(processId, params);
ksession.insert(wpi);
ksession.fireAllRules();

By inserting the workflow process instance you can reference process variables in the rule definition.

WorkflowProcessInstanceImpl( $myVariable: variables["myVariable"])

I am not sure though how to get the global variable, try this:

kcontext.getKnowledgeRuntime().getGlobal("myGlobalName");

Hope that helps,

Jiri
