JSP在tomcat里面不能执行

beansprouts1981

安装了JDK和JWSDP，所有的功能都正常（自己写代码编译，JWSDP里面的example的JSP程序执行）唯独自己copy的例程报如下错误：
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/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.

偶已经按照建议做了tools.jar的copy动作，但是重启tomcat后问题依旧，测试几个程序都是这样的问题，是不是没有找到编译器的缘故？可是在安装JWSDP的时候已经设置了SDK的路径啊，况且它自己的例程又执行的好好的，郁闷……

hello~world

No Java compiler was found !!


you should set JAVA_HOME=e:\j2sdk
