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.

Apache Tomcat/5.0.25

不能编译jsp文件
找不到jsp的源文件

问题解决了，把tool.jar文件复制到tomcat目录的comman\lib就可以了
另外，刚遇到个问题，sql2000必须装sp3才能用微软的jdbc。嘿嘿，希望大家别走弯路

不知道MS的那个驱动有什么好的
等你们以后做开发的时候就知道，ms的东东有多烂了
