jetty访问jsp页面出现异常:org.apache.jasper.JasperException: PWC6345: A full JDK (not just JRE) is required解决

今天在jetty下配置一个jsp模版的报表页面，报以下异常信息：

在网上找了不少资料，主要问题仍是jetty运行的jre环境配置问题，最终解决方案以下：
在eclipse—>Window—>prefence—>java—>Installed JREs,选择jre点击Edit找到jdk的安装目录，个人安装在C：Program Files/java/jdk1.7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。

提醒：网上的解决方案我试了不成功，主要缘由就是由于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）！！
