Note: all the images in this article are clearly indicated in the attachment.
Install jdk1.6, Tomcat 6, and myeclipse.

Second, download struts2
Step 1: Go to struts21 official website http://struts.apache.org/2.1.6/index.html
Click download now in Figure 1 below to download the full output in Figure 2. Decompress the package after download;

Step 2;
The integration of myeclipse tomcat is relatively simple, not to mention; create a web project named struts2;
Step 3;
Decompress the following six files in lib under the downloaded struts2-1-6 directory:
Commons-logging-1.0.4.jar
Freemarker-2.3.8.jar
Ognl-2.6.11.jar
Struts2-core-2.0.6.jar
Xwork-2.0.1.jar
And (because it is a struts2-1-6 version. So this file is also essential)
Commons-fileupload-1.2.1

Then paste it to WebRoot/WEB-INF/lib;
Step 4:
Create a login. jsp file in the WebRoot directory.
The Code is as follows:
Login. jsp
Jsp code

1. <% @ Page language = "java" import = "java. util. *" pageEncoding = "ISO-8859-1" %>
2. <%
3. String path = request. getContextPath ();
4. String basePath = request. getScheme () + ": //" + request. getServerName () + ":" + request. getServerPort () + path + "/";
5. %>
12. My JSP 'login. jsp 'starting page
26. 
    
    Step 5:
    Modify the web. xml file under the WEB-INF
    The Code is as follows:
    Web. xml
    Xml Code
    2. Xmlns = "http://java.sun.com/xml/ns/j2ee"
    3. Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"
    4. Xsi: schemaLocation = "http://java.sun.com/xml/ns/j2ee
    5. Http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd>
    8. Struts2
    11. Org. apache. struts2.dispatcher. FilterDispatcher
    17. Struts2
    19. /*
    21. 
        
        Step 6:
        Create action
        Create the com. test. action package in the src directory.
        Create an action in the package as follows:
        LoginAction. java
        Java code
        1. Package com. test. action;
        3. Public class LoginAction
        4. {
        7. // The getter and setter methods match the client information based on the method name.
        8. Public String getUsername (){
        9. Return username;
        10. }
        11. Public void setUsername (String username ){
        12. This. username = username;
        13. }
        14. Public String getPassword (){
        15. Return password;
        16. }
        17. Public void setPassword (String password ){
        18. This. password = password;
        19. }
        21. Public String execute () throws Exception
        22. {
        23. Return "success ";
        24. }
        26. // Corresponding to
        27. Private String username;
        28. Private String password;
        29. }
            
            Step 7:
            Struts configuration file
            
            The following code creates a struts. xml file in the src directory:
            Xml Code
            2. "-// Apache Software Foundation // DTD Struts Configuration 2.0 // EN"
            3. Http://struts.apache.org/dtds/struts-2.0.dtd>
            10. /Result. jsp
            13. 
                Note: The sentence in struts. xml is
                ! DOCTYPE struts PUBLIC
                "-// Apache Software Foundation // DTD Struts Configuration 2.0 // EN"
                Http://struts.apache.org/dtds/struts-2.0.dtd>
                
                The red sentence may report an error. The solution is to remove the "http: //" text. I don't know what else to do. If you have any knowledge, please give me some advice;
                
                Step 8;
                Create result File
                The following code creates a result. jsp file in the WebRoot directory:
                Jsp code
                1. ]
                2. <% @ Page language = "java" import = "java. util. *" pageEncoding = "ISO-8859-1" %>
                3. <%
                4. String path = request. getContextPath ();
                5. String basePath = request. getScheme () + ": //" + request. getServerName () + ":" + request. getServerPort () + path + "/";
                6. %>
                13. My JSP 'result. jsp 'starting page
                25. Helloworld
                26. Username: $ {requestScope. username}
                    
                27. Password: $ {requestScope. password}
                29. 
                    
                    So far, the code writing has been completed. Next is release;
                    Right-click the name of the struts2 project, select myeclipse from the menu, and select add and remove project ...... Then, figure 3 is displayed.
                    Select a project and click add to publish to the specified tomcat,
                    
                    Finally, open the browser. In the browser http: // localhost: 8080/struts2/login. jsp
