on lost focus of textbox. + JSP + Server side Validation.

[Jigar Naik]

I have 2 textbox in my .JSP file.

text1 & text2

I will enter some value in text1 and when the focus of text1 is lost, I want to check the value in my database table wather it is in database or not.

can anybody suggest me on same.
What technique should i use ?
I don't have any idea of how to do it...
The database table contains more than 100000 entries for that field.
I'm Using MVC architecture...

I'd strongly recommend making an Ajax request to the Controller, with the value of Text1. Configure the Controller so that it will pass the Text1 value to the Model, which should then verify whether the Text1 value is in the database and return true or false to the View.
