提问by borderwing
I just get confused about how to modify web.xml for multiple servlet. I got three servlet to handle three different jsp, but now only one servlet is effective.
我只是对如何修改多个 servlet 的 web.xml 感到困惑。我得到了三个 servlet 来处理三个不同的 jsp，但现在只有一个 servlet 有效。

You should declare and define the classes/servlets inside the web.xml file like this:
您应该像这样在 web.xml 文件中声明和定义类/servlet：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<servlet>
<servlet-name>LoginForm</servlet-name>
<servlet-class>com.project.system.LoginForm</servlet-class>
</servlet>
<servlet>
<servlet-name>RegisterForm</servlet-name>
<servlet-class>com.project.system.RegisterForm</servlet-class>
</servlet>
<servlet>
<servlet-name>UserController</servlet-name>
<servlet-class>com.project.controller.UserController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginForm</servlet-name>
<url-pattern>/LoginForm</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>RegisterForm</servlet-name>
<url-pattern>/RegisterForm</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>UserController</servlet-name>
<url-pattern>/UserController</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
</web-app>
