Problem beginning with JAVA

I'm reading the book JAVA SERVER PROGRAMMING form WROX.

I have created my first servlet HelloWorld.java

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet
{
    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
{
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
       out.println("<html>");
        out.println("<body>");
        out.println("<head>");
        out.println("<title>Hello World!</title>");
        out.println("</head>");
          out.println("<body>");
        out.println("<h1>Hello World!</h1>");
      out.println("</body>");
        out.println("</html>");

}
}

which works fine

Then I created a public class named HTML which is a HTML generator

package javacode.util;

public class HTML
{
public static final int NORMAL = 0;
public static final int HEADING = 1;
public static final int LINE = 2;

public StringBuffer buffer;
public HTML (String title)
{
buffer=new StringBuffer(4096);
this.buffer.append("<HTML><HEAD><TITLE>");
this.buffer.append(title);
this.buffer.append("</TITLE></HEAD><BODY>");
}

public void add(int style, String text, boolean linebreak)
{
switch(style)
{
case NORMAL:
this.buffer.append(text);
break;
case HEADING:
this.buffer.append("<H1>");
this.buffer.append(text);
this.buffer.append("</H1>");
case LINE:
this.buffer.append("<HR>");
break;
default:
break;
}
if(linebreak)
{
buffer.append("<BR>");
}
}

public String getPage()
{
this.buffer.append("</BODY></HTML>");
return this.buffer.toString();
}
}

How can I use this class in other servlets?

I tried to make it jar file and import it in another servlet and when I deployed it I got the following message:

java.lang.NoClassDefFoundError: javacode/util/HTML
