初学者，进者有分，高手帮忙测试的显示问题。

[sunboby]

我装的j2sdk1.4.2_06+Tomcat 5.0来做jsp
安装目录为C:\Tomcat 5.0 和C:\j2sdk1.4.2_06
我的.java的程序能编译通过，http://localhost:8080测试也能正长显示
以下是我的环境变量
CLASSPATH %JAVA_HOME%\lib;%TOMCAT_HOME%\lib;C:\Tomcat 5.0\common\lib\servlet- api.jar;.;C:\j2sdk1.4.2_06\lib\dt.jar;C:\j2sdk1.4.2_06\lib\tools.jar
JAVA_HOME C:\j2sdk1.4.2_06
PATH %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\80\Tools\BINN;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\j2sdk1.4.2_06\bin;C:\Tomcat 5.0\bin
TOMCAT_HOME C:\Tomcat 5.0
我把我做的jsp文件放到了C:\Tomcat 5.0\webapps\myweb 文件夹下了。也建了WEB-INF文件夹里面有web.xml文件
为什么我访问http://localhost:8080/myweb/test.jsp时出错呢。

高手帮我看看。解决马上给分

[zlsunnan]

应该是web.xml的错误
给出例子

我配置的时候classpath,path都是.;在前.
只是在webapps下添加一个目录test,在里面键个WEB-INF,web.xml,重起tomcat,我就能访问http://localhost;8080/test

[monkeyhjl]

配置C:\Tomcat 5.0\conf下的server.xml文件。
<Context path="/myweb" docBase="C:\Tomcat 5.0\webapps\myweb" debug="0" reloadable="true">
