Give a look at the Servlets / JSP API's.
especially the com.sun.image.codec.jpeg.JPEGImageEncoder ...
this example shuld be almost compilable !

package org.test.servlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.sun.image.codec.jpeg.*;
import java.awt.image.BufferedImage;
public class ShowGraphics
  extends HttpServlet
{
  public void doGet ( HttpServletRequest request,
                      HttpServletResponse response )
    throws ServletException, IOException                      
  {
    PrintWriter out = response.getWriter ();
    JPEGImageEncoder img = JPEGCodec.createJPEGEncoder (response);
    
    BufferedImage bi = new BufferedImage(ImageWidth + 10, 
                                         ImageHeight, 
                                         BufferedImage.TYPE_BYTE_INDEXED);
    
    graphics = bi.createGraphics();
    // Create your image here
    // g.drawString ("Hello World", 0, 0);
    // Draw your string here !
        
    img.encode (bi);
    response.setHeader ("Content-Type", "image/jpeg");
    response.flushBuffer ();    
  }  
}

Other inspire your self from javaworld
