Hi Bala!
Do you mean for your radio buttons to be from different groups? In your note above, radio 1 sets "param1" and radio 2 sets "param2". It would be more logical to have both radios set "paramX" with value 1 or value 2.
To make this more clear, the HTML code would look like so:
<INPUT TYPE="radio" NAME="MyRadio" VALUE="Yes">
<INPUT TYPE="radio" NAME="MyRadio" VALUE="No">
Since you are already using a form, use an image that looks like an HREF to submit.
<INPUT TYPE="image" SRC="LooksLikeAnHref.gif">
If the action of your form is the
servlet, clicking on the input image will submit paramX to the servlet.
Hope this helps!
