Exception in thread "main" java.lang.NoClassDefFoundError

[titans]

Hello everybody. I am writing "hello world" in Java using Spring. So what I did.
1) The Eclipse EE Indigo has created a new Java Project.
2) I downloaded spring-framework-3.1.1.RELEASE unpacked into a directory. Have the files in the directory dist (there are many, for some reason I thought that I needed to take a "spring.jar") from org.springframework.aop-sources-3.1.1.RELEASE.jar ending org.springframework.web-sources -3.1.1.RELEASE.jar
3) I created the four files. The first is the 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="greetingService" class="ua.maybe">
         <property name="greeting" value=" VIZA!" />
</bean>


</beans>

Second class with void main

package ua;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;

public class Full {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		//maybe m=new maybe();
		//AbstractApplicationContext ctx=FileSystemApplicationText;
		 BeanFactory factory = new XmlBeanFactory(new FileSystemResource("da.xml"));

		 Maybe greetingService = (Maybe) factory.getBean("greetingService");

         greetingService.sayGreeting();

	}

}

Made another class

package ua;



public class Maybe implements Gast {
	 private String greeting;
	Maybe(){}
	public void sayGreeting()
	{
		System.out.println("Hello Spring! "+greeting);
		
	}
    public void setGreeting(String greeting) {
        this.greeting = greeting;
    }
}

And the end made interface

package ua;

public interface Gast {
	void sayGreeting();
}

After that, compile the project and get the error. Why is it so?

I would guess that Spring Framework has some dependency on Apache Commons Logging, but the distribution you downloaded only included the Spring Framework and not its dependencies. Browsing http://www.springsource.org/download/community it appears that Spring 3.0.2 was the last release to include its dependencies with the download.

use commons-logging.jar to resolve this issue
