How is submit a form using ahref in a JSP

Question

I have a form inside a iframe. It has 2 buttons. On clicking one button resultant page should open in the parent window(i.e target = parent). On clicking another button resultant page should open in same window (i.e target = self).
In bith case i need to submit the details in that form. I need to do this when java script is disabled. When java script is enabled changing of target window is possible.

I have written a few applications that required this kind of function, and what I ended up with was an applet.
First, I submit to the usual ACTION-URL and after processing the data, my code would determine whether the response should capture the full screen, or appear just withing the frame.
For redirects that capture the full browser window, I would call a page (still within the frame) that would run a Java applet whose only funtion is to send the browser to the new URL, which would be sent to the applet as a param. The applet just needs to know how to send the user to the new URL.
package com.redeye.core.utils;
import java.applet.Applet;
import java.net.MalformedURLException;
import java.net.URL;
* Redirect the user agent to a new URL.
* Usage:
* <xmp>
* <applet

*   mayscript>
*     <param
*       name="targeturl"
*       value="http://target.url.here/">
*     <param
*       name="targetframe"
*       value="_self|_top|ANYTHING_ELSE">
* </applet>
* </xmp>
* Parameters:
* <b>targeturl:</b> The target to which the user agent is redirected
* <b>targetframe:</b> name of the frame/window to be redirected

public class Deflector extends Applet
     private static final long serialVersionUID = -878236489812416561L;
      * Constructs a new Deflector applet
     public Deflector()
          // Default contructor
      * Initializes the Deflector applet
     public void init()
          super.init();
          try
               String url = getParameter("targeturl");
               String target = (getParameter("targetframe") != null) ? getParameter("targetframe") : "_top";
               if (null != url)
                    getAppletContext().showDocument(new URL(url), target);
          catch (MalformedURLException mue)
               System.out.println("Error in target URL: " + mue.getMessage());
}
