eclipise中jetty访问jsp页面出现异常错误的解决方案

原文地址：http://www.th7.cn/Program/java/201212/116236.shtml

最经接触jetty，还不是很熟悉，利用eclipse开发调试jsp页面时，每次访问jsp页面时出现500错误，找到后台，控制台提示如下信息：

在网上找了很多资料，主要问题还是jetty运行的jre环境配置问题，最终解决方案如下：

在eclipse——>Window——>prefence——>java——>Installed JREs,选择jre点击Edit找到jdk的安装目录，我的安装在C：Program Files/java/jdk1.6.0.23.在jdk安装目录下找到jre目录，点击finish。，启动项目，访问jsp页面，一切正常。





PS:网上的解决方案我试了不成功，主要原因就是因为jre配置环境的错误，在选择jre环境的时候，有两个选择，一个是java根目录下的jre（选择这个会不成功），一个是在jdk根目录下的jre（选择这个成功）！！希望能帮助刚接触jetty的朋友们
