Running .jar files in DOS

[x-ice]

I have made a .jar file that is supposed to run in DOS, but when i execute it (through DOS) nothing happens. How can i get it to run in DOS? If it is any help here is my code.

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Student
{

  	private static String Teacher;
	private static String StudentName;

	/**
	 * Create a student
	 *
	 * @param StudentName
	 */
	public Student()
	{
		//Do nothing!
	}
	
	public static void main(String[] args)
	{
	    Student student = new Student();
	    	    
	    Teacher = "Mr Whyley";
	    StudentName = getUserInput();
	    //Print details
        System.out.println("Student Name: " + StudentName);
        System.out.println("Teacher: " + Teacher);
	}

	/**
	 * Get teacher name for a student
	 * 
	 * @return Teacher
	 */
	public String getTeacher()
	{
		return Teacher;
	}
	
	public static String getUserInput()
	{
	    String StuName = "Unknown";
	    //Print the message
	    System.out.print("What is the student name? ");
	    //The input reader
	    BufferedReader UsrInput = new BufferedReader(new InputStreamReader(System.in));
	    try
	    {
	        //Assign user input to the buffered reader
	        StuName = UsrInput.readLine();
	    }
	    catch(java.io.IOException Ex) 
	    {
            System.out.println ("An error has occured: " + Ex.getMessage());
        }
        System.out.println(); //Blank line;
        //Return user input
	    return StuName;
	 }
	   
}

I didn't know java could run in DOS...wouldn't you need a Java interperter for DOS?
Guess I was wrong

[System_Error]

What do you mean run in dos? Run it from dos?

If so,


java -jar JarFile.jar

[System_Error]

You do have a manifest file in your jar right? You'll need to specify a main-class header.

There is no manifest. I compiled the .jar file using BlueJ.

[System_Error]

Have you tried listing the contents to see if it's there?

I think this lists:

jar tf JarFile.jar
