1.Software

• Java 1.6
• Eclipse Helios
• Spring Framework 3.1.1
  Download Page: http://www.springsource.org/download
  Download: spring-framework-3.1.1.RELEASE.zip 27.4 MB
• Apache Commons Logging
  Download Page: http://commons.apache.org/logging/download_logging.cgi
  Download: commons-logging-1.1.1-bin.zip 1.02 MB

2.Create User Libraries:

In Eclipse you need 2 user libraries: spring-framework-3.1.1 and commons-logging

Create user library: spring-framework-3.1.1

• Extract spring-framework-3.1.1.RELEASE.zip to C:Javalibrariesspring-framework-3.1.1.RELEASE
• In Eclipse: Menu Windows → Preferences
• → Click Java→Build Path→User Libraries→Click Button New…
• → Input in field User library name: spring-framework-3.1.1
• → Ok
• → Click Button Add JARs..
• → Select all JAR file from C:Javalibrariesspring-framework-3.1.1.RELEASEdist

Create user library: commons-logging-1.1.1

• Extract spring-framework-3.1.1.RELEASE.zip to C:Javalibrariesspring-framework-3.1.1.RELEASE
• Do the same steps like user library spring-framework-3.1.1, create the user lirary commons-logging-1.1.1,
  add only JAR file: commons-logging-1.1.1.jar

Note: Without Apache Commons Logging you get the error message:
Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

3. Create Project in Eclipse

• Create a Java Project exm. Spring_QuickStart:
  Menu File → New → Java Project
• Add User Libraries:
  Right click Project Spring_QuickStart → Build Path → Add Libraries → User Libraries →
  add the user libraries spring-framework-3.1.1 and commons-logging

4.Create a simmple Java class

package model;

public class Prompter {
	private String message;

	public void prompt() {
		System.out.println(message);
	}

	public void setMessage(String message) {
		this.message = message;
	}
}

5.Create file ..src/beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
	 http://www.springframework.org/schema/beans/spring-beans.xsd">

	<bean id="myPrompter" class="model.Prompter">
		<property name="message" value="Here is my first Spring program!"></property>
	</bean>
</beans>

6.Create a Test Class

package model;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext(
				"beans.xml");

		Prompter p = (Prompter) context.getBean("myPrompter");
		p.prompt();
	}

}

7.Run Test

Run Class App as Java Application, you see this in the Console:

19-Mar-2012 11:41:39 org.springframework.context.support.AbstractApplicationContext prepareRefresh
INFO: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@133f1d7:
