setting up Spring in Eclipse - context initialization failure

krenkz :

I am trying to set up Eclipse (being a newbie in Java and Eclipse and Spring) following this tutorial and when trying to run a simple HelloWorld.java, I get this error in my console

I cannot figure out what is wrong?

my code in HelloWorld.java

package com.tutorialspoint;

public class HelloWorld {
   private String message;

   public void setMessage(String message){
      this.message  = message;
   }
   public void getMessage(){
      System.out.println("Your Message : " + message);
   }
}

my code in MainApp.java

package com.tutorialspoint;

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

public class MainApp {
   public static void main(String[] args) {
      @SuppressWarnings("resource")
    ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
      obj.getMessage();
   }
}

It would be helpful if you supply us with the java code. But, based on the errors I believe there is a corrupted file when you were installing the program. Make sure there are no restrictions on the computer you are using and reinstall the program Use this tutorial instead. Hope That Helped!
