What I want is to set a variable while completing a task. The following is what I do : //Just before task complete I call the following code. StatefulKnowledgeSession kSession = BpmRepositoryConfig.createSession();   ProcessContext kContext = new ProcessContext(kSession);   ProcessInstance processInstance = kSession.getProcessInstance(taskData.getProcessInstanceId());   logger.info("ProcInst : "+processInstance.getId());   kContext.setProcessInstance(processInstance);   for (Entry<String, Object> entry : map.entrySet())   {       logger.info(entry.getKey() + "/" + entry.getValue());       if(!(kContext == null))        kContext.setVariable(entry.getKey(), entry.getValue());       else        logger.severe("KContext is Null");   }   KContext is not null. But it throws the following NPE : [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R java.lang.NullPointerException [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R  at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:68) [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R  at org.jbpm.process.instance.impl.ProcessInstanceImpl.getContextInstance(ProcessInstanceImpl.java:133) [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R  at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setVariable(WorkflowProcessInstanceImpl.java:238) [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R  at org.drools.spi.ProcessContext.setVariable(ProcessContext.java:68) [3/7/13 10:47:46:951 COT] 00000110 SystemErr     R  at pe.com.bcp.model.BpmAPI.createTaskVariables(Unknown Source) Need help please.
