In Key Events shall we call "action" attribute

[Neelu]

In my form i have one textbox whenever i will give data( nearly 2 to 3
characters), the key press event should go and call to some jsp for
fetching data from database depend upon the data given. I got this by
using submit button. I need this one using key event. Is it possible?

I guess you can do it..

Code would look something like this

textbox.addKeyListener(
new KeyListener() {
int i=0;
void keyPressed(KeyEvent e) {}
void keyReleased(KeyEvent e) {}
void keyTyped(KeyEvent e) {
i++;
if(i>2) //if number of characters entered is > 2
{
// Do some action
}
}
}
);

Your problem is that you asked what probably is a JavaScript question
in a Java newsgroup.

You got a Java code response, but used it as JavaScript Code...
Two different languages with some syntactic similarities...

Try "comp.lang.javascript".
