tomcat中server.xml配置对项目的影响！5.5

janneyabc

　　host下配置context，其中有path和docbase2个属性，我将path设置为/ 运行项目打开浏览器查看源码显示path=request.getContextPath();是一个斜杠，所以这个是不对的，果断设置为空。设置为空就默认是得到项目的名！即WEB-INF的父目录名！
　　看到的朋友能不能帮我解决一个问题：
　　我这个项目2个地方部署，一个在万网，一个是自己装的VPS中，万网一切正常，但是VPS中的部署好后也可以访问，打开首页的什么都没问题，但是老是报一个奇怪的异常，经查看好像是无法获取session，例如验证码是存放在session里的，然后action里从session中拿到该值，却为空！每次都是这样，本地、万网，服务器都没有问题，请问是什么问题！
　　错误代码：
