  • WebApplicationContext is the child of plain ApplicationContext. It is used in web applications. It provides features to deal with web-related components like- controllers, view resolvers etc.
public interface WebApplicationContext extends ApplicationContext
  • A Web Application can have multiple WebApplicationContext to handle requests.
  • Each DispatcherServlet is associated with one WebApplicationContext.

Create Web Project

  • Open Eclipse
  • Go to File -> New -> Dynamic Web Project
  • Create IOC-Web project
  • Right click on project -> Build Path -> Configure Build Path -> Libraries tab -> Add External JARs (Used 2.X jars)
    - commons-logging-X.X.jar
    - spring-beans-X.X.X.jar
    - spring-context-X.X.X.jar
    - spring-core-X.X.X.jar
    - spring-web-X.X.X.jar
    - spring-webmvc-X.X.X.jar
  • Also add these jars into WEB-INF/lib folder
  • * You can find dtd information from spring-beans-X.X.X.jar -> org -> springframework -> beans -> factory -> xml -> spring-beans.dtd (line no 36 & 37)

/* get bean object */

return modelAndView;

<form action="./hello.code">
Name: <input type="text" name="name">
<input type="submit" value="Submit">
<p>Hello ${msg}</p>
  • Right click on project -> Run As -> Run As Server
