Give multiple buttons the same name, but different values.
Your servlet then only has to look for the one parm, and use different values to
decide what to do:
<form action=/servlet/.....>
<input type="SUBMIT" NAME="BUTTON" VALUE="First">
<input type="SUBMIT" NAME="BUTTON" VALUE="Second">
</form>
in your program:
String buttonValue = req.getParameter("BUTTON"):
if (buttonValue.equals("First"))
{
// do button1 stuff
}
else if (buttonValue.equals("Second"))
{
// do button 2 stuff
}

Subject: How to know which form button was pressed?
Hello all,
I'm developing a mini applications server for internal purposes, and now I'm
facing with a problem: suppose I have the following html code:
<form action=/servlet/.....>
<input type="SUBMIT" NAME="btn_1" VALUE="First button">
<input type="SUBMIT" NAME="btn_2" VALUE="Second button">
</form>
How do I know when user press the 1st or the 2nd button?
Thanks in advanced
