Today, servlet is used, so Tomcat is used. ^ _ ^, but after a simple small example is written, the ghost error HTTP status 404 is suddenly reported after Tomcat is started. in fact, there are many causes for such errors as 404. Here I will only share some of my problems here.
First, I wrote a servlet with the following code:
<Body>
<Form name = "myform" Action = "Test2" method = "Post">
<H2 align = "center">
User Information
</H2>
Name:
<Input type = "text" name = "name">
<Br>
Age:
<Input type = "text" name = "Age">
<Br>
Gender:
<Input type = "text" name = "sex">
<Br>
<Input type = "Submit" value = "Submit">
<Input type = "reset" value = "clear">
</Form>
</Body>
</Html>
The Web. xml file is configured as follows:
<? XML version = "1.0" encoding = "UTF-8"?>
<Web-app version = "2.4" xmlns = "http://java.sun.com/xml/ns/j2ee"
Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"
Xsi: schemalocation = "http://java.sun.com/xml/ns/j2ee
Http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd>
<Servlet>
<Servlet-Name> test </servlet-Name>
<Servlet-class> com. myservlet </servlet-class>
</Servlet>
<Servlet-mapping>
<Servlet-Name> test </servlet-Name>
<URL-pattern>/Test2 </url-pattern>
</Servlet-mapping>
</Web-app>
In fact, my problem mainly lies in <form name = "myform" Action = "Test2" method = "Post">, Because I added a/before Test2 of action /, so I reported that kind of ghost error. I remember that I used to add/When I used it. At that time, there was no such error, but this time it would not work. no matter how it works, this time it should be OK. also, I want to remind you that the formaction OF THE FORM seems to be added/when you use struts later /. if a similar error occurs, you can pay attention to it.
