how to identify which button is pressed in struts!!!

[Hd Desai]

hello,
i am building a web application in which i have 3 buttons for edit,save and cancel.
now i am using struts ....
i have images as buttons...so the problem is i m not able to identify which button is pressed....i have seen documentation of struts for image tag,it gives X and Y co-ordiante but thats not correct solution because depending on resolution my X and Y coordinate can change...
and one another contsratint is i don;t have to use JavaScript
so please help me..i am stuck at this point...

This is code I use, based on Ted Husted's:

/*
 * ImageButtonBean.java
 */
/**
 * Bean used in conjunction with the Struts
 * <code><html:image></code> tag.
 * 
 * @see <a href="http://husted.com/struts/tips/001.html" target="_blank" rel="nofollow">http://husted.com/struts/tips/001.html</a>
 */
public final class ImageButtonBean {
    private String x;
    private String y;
    /**
     * Clears this button's state
     */
    public void reset() {
        x = null;
        y = null;
    }
    /**
     * Returns true if the associated button in the form was clicked
     */
    public boolean isSelected() {
        return ((x != null) || (y != null));
    }
    
    public String getX() {
        return (this.x);
    }
    public void setX(String x) {
        this.x = x;
    }
    public String getY() {
        return (this.y);
    }
    public void setY(String y) {
        this.y = y;
    }
}

// In Action form:
  
    private ImageButtonBean saveButton = new ImageButtonBean();
    private ImageButtonBean cancelButton = new ImageButtonBean();
     
    // add getters and setters for the above 
    public void reset(...) {
       ...
       saveButton.reset();
       cancelButton.reset();
       ...
    }

To see if a certain button is selected, just invoke the isSelected() method.
