tomcat web.xml 配置问题

[swordkee]

已经加入如下代码,但是出现错误时并没有重定向


<error-page>
<error-code>404</error-code>
<location>unavaiable.jsp</location>
</error-page>

<error-page>
<exception-type>java.io.FileNotFoundException</exception-type>
<location>unavaiable.jsp</location>
</error-page>

[老土豆T]

<location>/unavaiable.jsp</location>
注意反斜杠，因为这样会早站点跟目录下， 否则视为相对目录。。

看看是不是这个原因，上面写的是对的。

[geleisi]

这段代码启到什么作用？是不是出现404错误找不到页面的时候自动返回unavaiable.jsp叶面？为什么我加到web.xml里面不起作用呢？

[whyxx]

应该是目录结构的问题,如果unavaiable.jsp在根目录下应该在前面加上/unavaiable.jsp,否则在哪个目录要写上相对目录路径

[swordkee]

是在跟目录下.

[swordkee]

也加了.但是不行.是一样的.

[swordkee]

大家帮帮忙.谢了

c:\tomcat\conf 目录下 server.xml文件配置：
加上
<Context path="/cyvod" docBase="d:/cyvod" debug="0" reloadable="true">

然后在自己的cyvod文件夹里建立 WEB-INF 文件夹 并配置 web.xml文件如下（这个文件也是自己建立的）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>UserManageServlet</servlet-name>
<servlet-class>user.UserManageServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>UserManageServlet</servlet-name>
<url-pattern>/manage/UserManageServlet</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>manageservlet</servlet-name>
<servlet-class>manage.manageservlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>manageservlet</servlet-name>
<url-pattern>/manage/manageservlet</url-pattern>
</servlet-mapping>
</web-app>
在 WEB-INF 文件夹下建立一个classes 文件夹
把你的类及SERVLET都放到里面就可以了
至于JSP文件放到 cyvod这个文件夹下就可以运行了
这样配置出来的路径是：
d:\cyvod
、、、、、myfirst.jsp 你自己的JSP文件
、、、、、WEB-INF
、、、、、、、、、web.xml
、、、、、、、、、classes
、、、、、、、、、、、、、你自己的类文件和SERVLET文件，例如：user.class

[swordkee]

你写的我没看懂.我是要错误重定向.为什么需要servlet?

下面的没问题
