Running .jar files in DOS

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.

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 :p

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

If so,


java -jar JarFile.jar

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.

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

I think this lists:

jar tf JarFile.jar
