急啊,大家帮忙看看
大家帮帮忙这是什么错误啊,这个JSP页面在本地测试没问题,但放到服务器上就出现下面的错误.
org.apache.jasper.JasperException:   Unable   to   compile   class   for   JSP

No   Java   compiler   was   found   to   compile   the   generated   source   for   the   JSP.  
This   can   usually   be   solved   by   copying   manually   $JAVA_HOME   b/tools.jar   from   the   JDK  
to   the   common   b   directory   of   the   Tomcat   server,   followed   by   a   Tomcat   restart.  
If   using   an   alternate   Java   compiler,   please   check   its   installation   and   access   path.

------解决方案--------------------
提示很清楚啊
没有找到编译JSP的Java编译器，这通常可以通过手动拷贝JDK下的$JAVA_HOME b/tools.jar 到Tomcat下的common的lib目录，然后重启Tomcat进行解决。

------解决方案--------------------
无法解释jsp,解决方案同一楼
------解决方案--------------------
没装jdk吧
------解决方案--------------------
服务器不在本地，能不能改嘛？不能改就只有先在本地编译再传到服务器上了。
------解决方案--------------------
晕,服务器也是需要装jdk的,跟服务商联系
------解决方案--------------------
No Java compiler was found to compile the generated source for the JSP.

如果你的JDK有多个的话，你要在环境变量中都设置一下，当你用当前JDK的话
