Shortly after getting started with struts of Jsp, I had to learn spring and then combine the two. So I found a lot of examples about struts + spring on the Internet, but they are basically EXAMPLES OF a, and then re-compile a book based on its principles to implement the example with struts.
I. Runtime Environment
1. eclipse-SDK-3.2
2. MyEclipse GA5.0
3. apache-tomcat-5.5.20
4. Strust1.2
5. Spring1.2
Ii. documents required for the project
1. index. jsp
2. login. jsp
3. reinput_blank.jsp
4. reinput_error.jsp
5. success. jsp
6. LoginActio. java
7. LoginForm. java
8. struts-config.xml
9. applicationContext. xml
Step 3
1. Build a project
Create a Web Project named Welcome_SS
File-> New-> Project-> Web Project, "next" Project Name: "Welcome_SS", "finish ";
2. Import the struts package
Right-click the Welcome_SS project and choose "Myeclipse" from the shortcut menu. Choose "Add struts Capabilities..." from the shortcut menu ......, Select struts1.2 and finish;
3. Import the spring package
Select the Welcome_SS project, right-click-> Myeclipse (or choose Myeclipse on the menu bar)-> Add spring Capabilities ......, By default, select Spring 1.2 AOP Libraries-<MyEclipse-Library> and Spring 1.2 Web Libraries-<MyEclipse-Library>, and then finish;
(Why do I have to select these two)
Note: you may need to add several spring packages under the lib folder,
Spring. jar,
Spring-1.2.6.jar,
Spring-aop.jar,
Spring-beans.jar,
Spring-context.jar,
Spring-core.jar,
Spring-orm.jar,
Spring-remoting.jar,
Spring-support.jar,
Spring-web.jar,
Spring-webmvc.jar
4. write code (pages and required classes)

6. Deploy and start Web Service (Tomcat)
(For details, refer to another article: two deployment methods of Tomcat in Myeclipse)
A. Under apache-tomcat-5.5.20 "conf, locate server. xml, open it, and add a sentence before </Host>.
<Context path = "/wess" debug = "0" docBase = "C: Documents and SettingsttworkspaceWelcome_SSWebRoot" reloadable = "true"> </Context>
Note: C: Documents and SettingsttworkspaceWelcome_SS are the storage path of the project.
B. on the toolbar of Myeclipse, find a button that looks like a chassis. Click it to open the Tomcat server.
7. Run
Enter http: // localhost: 8080/wess In the IE browser to run the program! If the user name and password are both success.
