此处选择的设置确保在同一物理机器上同时启动3个实例不会冲突。如果实际在网络中的3个物理机器上进行测试，它们可以都使用表中的Machine1.。

加粗的标识根据实际需要变更。

每个需要集群应用的web.xml 中加入以下配置：
<distributable/>
创建测试 session.jsp内容如下：
<%
//HttpSession session = request.getSession(true);
System.out.println(session.getId());
out.println("<br> SESSION ID:" + session.getId()+"<br>");
%>
访问session.jsp查看.
