------解决方案--------------------

楼主，今天碰到跟你一样的问题。

这里说下我的解决办法，你可以参考一下：

问题产生是应为，project的lib和tomcat的lib下面都用jsp-api.jar;

在project的lib中删除jsp-api.jar，接着通过Build path的方式将tomcat的lib下面的jsp-api.jar引进来，

OK！问题解决。

------解决方案--------------------

java.lang.ClassNotFoundException: org.apache.taglibs.standard.tlv.JstlCoreTLV

有一个标签库没引进来吧？

我的异常网推荐解决方案：The server encountered an internal error () that prevented it from fulfilling this request.,http://www.myexception.cn/java-web/317.html

是因为jar包的冲突，，引入进来的jsp-api.jar包和tomcat中的jar冲突的了。。。删掉引入进来的就可以
