--------------------------------------------------------------
you have to cast the processInstance to WorkflowProcessInstanceImpl:
use : 
WorkflowProcessInstanceImpl processInstance = (WorkflowProcessInstanceImpl) ksession.getProcessInstance(processInstanceId)
or 
WorkflowProcessInstanceImpl instance=(WorkflowProcessInstanceImpl) ksession.startProcess("org.jbpm.sample.hello",paras);

and  processInstance*.*getVariable("ret");

this is working from me

*HTH
