TOMCAT服务器，JSP测试程序内容如下：
<% out.print("Welcom"); %>
测试结果：
HTTP Status 500

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.

classpath,path的问题！

[edward0716]

都设置了。
classpath=c:\jdk\lib
path=...;c:\jdk\bin;c:\jdk\lib
按手册上所说的一样

你的TOMCAT安装路径是？

[yshgfly]

是不是 没装JDK啊，如果装了就把jdk目录\bin\tools.jar; 写入classpath环境变量

[lsy110]

需要把tomcat中的servlet.jar加入classpath路径中像：
.;%JAVA_HOME%\lib;%TOMCAT_HOME%\common\lib\servlet-api.jar

[Sakuragi2008]

按他说的 JDK 看来是装了 可能是TOMCAT的配置问题

[edward0716]

我觉得关键问题就在于路径上面。
到底有几个路径变量呢？
我加了path,class-path,tomcat-home,java-home
老是编译JSP出错。
但为什么实例可以执行呢？

[edward0716]

能把你们安装成功的PATH等变量给在下看看行吗？

[androwdelphi]

设path,class-path这两个就够了
