jbpm的系统数据库和我自己的系统数据库是分开的，两个数据库

/**
	 * 启动流程实例
	 * 
	 * @return
	 */
	public ProcessInstance startWorkflowProcess() {
		ProcessInstance pi = null;
		try {
			HornetQHTWorkItemHandler hornetQHTWorkItemHandler = new HornetQHTWorkItemHandler(
					ksession);
			ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
					hornetQHTWorkItemHandler);
			pi = ksession.startProcess(processName, params);
			
		} catch (Exception e) {
			e.printStackTrace();
		}
		return pi;
	}

程序在调用这个函数启动实例流程的时候报事务错误：
