急切需要帮助：jsp的安装环境的设置（还会加送分值）

[babygreens]

我在调试login.jsp时显示的错误提示：
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 28 in the jsp file: /login.jsp

我已经安装了jdk和tomcat，我还需要安装apache吗，还需要针对servlet进行什么设置吗，请大家帮助我

谢谢木木！
早看到就好了！
有没有WLS81的详细介绍！

UP

[Flarezhao]

thanks

[scorpionyjg]

感激不尽！！！多谢木木！

[xmqds]

找本最基本的书上都有.

[yaray]

javax.servlet.http.HttpSession 没有logout()方法吧
如果是要使当前session无效,可以使用它的invalidate()方法.

[wandou999]

贴出远码

[scorpionyjg]

迷惑：昨天还好好的，今天竟然出现：

E:\tomcat\jakarta-tomcat-4.0-b1\bin>startup
系统找不到指定的路径。
E:\tomcat\jakarta-tomcat-4.0-b1\bin>
这是怎么回事？在线等。。。谢谢！

[scorpionyjg]

tomcat 怎么起不来了？设置没动啊？

[scorpionyjg]

你简直就是jsp初学者的 救世主 我苦恼了n天的问题 一下子 就解决了 ！！太谢谢了！！
关于 tomcat的配置 我有更简单的方法 （前提条件是：win2000，tomcat 5。0）这也是csdn的一个高手给我说的！follow me!
一：用editplus 打开 C:\jakarta-tomcat-5.0.19\bin下的startup.bat文件 在
rem ---------------- 和 rem Guess CATALINA_HOME if not defined 两行之间（这两行一定要看清）添加 两行 如下的命令 ：set JAVA_HOME=c:\jdk 和
set CATALINA_HOME=c:\jakarta-tomcat-5.0.19 （其中c:\jdk 和c:\jakarta-tomcat-5.0.19 分别代表 jdk工具包的安装路径和tomcat的安装路径）
二：保存 退出 重启tomcat 搞定！

[joy19]

真是太详细了！我只能UP了！

[scorpionyjg]

运行 startup.bat
屏幕一闪，什么都没发生。tomcat 没启动！高手指点

请大家帮我看一下

To banni2003(木木) ：
我是按照你的上边的说明来设置的，但是运行JSP时提示如下的错误。如果是XML文件就不会有此类的错误。
请问是什么原因。是不是设置servlet.jar时有错误。没有找到这个包里边的工具。那我要如何设置。才可以正确。

我的环境变量设置如下：
path:=C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\j2sdk1.4.1_03\bin;D:\java3;
D:\Tomcat 5.0\common\lib\servlet.jar
classpath:=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;D:\Tomcat 5.0\common\lib\servlet.jar
JAVA_HOME:=C:\j2sdk1.4.1_03
CATALINA_HOME:=D:\Tomcat 5.0
CATALINA_BASE:=D:\Tomcat 5.0



但是错误如下：

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

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.
