Hi,
  I am new to JBPM I have following issues please help me
Once we start a ProcessInstance by 
 ProcessInstance processInstance = ksession.startProcess("com.sample.test"); 
I want to get the same process instance in a different thread to do something like this 
 ksession.signalEvent("Yes", "YesValue",processInstanceId); 
1) How can I achieve that ? 
a) I tried  ksession.startProcessInstance(processInstance.getId()); 
    which is returning different "processInstance". 
 b) I tried    Process process = ksession.getKnowledgeBase().getProcess("com.sample.test"); 
   but this is not giving ProcessInstance 

2) What is the relation between Process and ProcessInstance. 
3) I tried to persist in in postgres with com.sample.ProcessMain . 
   loadStatefulKnowledgeSession needs a Transaction Manager which class needs to be set here ? 
4) Also for Standalone run  I need InitalContext to bind Datasource how can I achieve that ? 
5) How to use inbox  and how i put my workflow items in inbox 
6) Is there any other API to get items which are in workflow 
7) Also need location of  JavaDocs for org.jbpm
