org.apache.jasper.JasperException: Unable to compile class for JSP:

今天在跑老项目的时候出现了一个问题，eclipse报错：

org.apache.jasper.JasperException: Unable to compile class for JSP:

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 1 in the generated java file The type java.io.ObjectInputStream cannot be resolved.

具体意思就是无法编译jsp，环境使用的是tomcat8，是无法进行编译的，这个问题导致页面访问的时候都是那种500的错误

最终根据猜测应该是环境问题，tomcat问题，

修改eclipse中tomcat的版本，最终修改为tomcat7，所以最终编译成功
