今天打算自己搭建一个jetty服务器,没有想到会遇到挺多麻烦,其中之一就是会报PWC6345错误,在网上找了不少解决方案,都没有解决,下边这种方式则一针见血,切中要害:

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

非常感谢这位博主的不吝分享!
