I have installed MyEclipse in my computer and now i want to start working with spring. From where can i start. I only know that spring is a framework and nothing more. What application does it supports? Which type application it builds?

I have heard that it has some relationship with java beans. I also dont know java beans, so how can i start working with spring.

Is there any settings i have to make in myEclipse to build spring application.
Please give me steps to print "Hello World!" using spring...

Well it appears you are just looking for information so here are two great sources that will show you Spring as well as a place to go for Spring specific questions and to get information on everything you want to know about Spring.

Springsource is the company that develops spring and the website below has tons of documentation, forums, tools etc for Spring...

Springframework.org - Tons of Spring related info

The important part to get you started is the introduction to the framework. Here is the link to an article that talks about it and gets you started understanding the idea behind the framework...

Enterprise Java Community: Introduction to the SpringFramework 2.5 - theserverside.com

That should get you moving in the right direction.

Same as in ordinary Java:

public static void main(String[] args) {
  System.out.println("Hello world!");
}

So, assuming you know what you want to use Spring for, which part of Spring are we talking about exactly? Inversion of Control?

class HelloWorld {
  private HelloFactory bean;

  public void setHelloFactory (HelloFactory bean) {
    this.bean = bean;
  }

  public HelloWorld() {
  }

  public void doHello() {
    System.out.println(bean.createHello());
  }
}

class HelloFactory {
  public HelloFactory() {
  }

  public String createHello() {
    return "Hello world!";
  }
}

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

    // an ApplicationContext is also a BeanFactory (via inheritance)
    BeanFactory factory = context;

    HelloWorld hw = (HelloWorld) factory.getBean("hello");
    hw.doHello();
  }
}
