Does this have anything to do with JavaScript? Looks like a JSP problem.

[madhuriks]

yes ..it will validate..if the textarea left blank it should throws an alert...its a jsp page and im using EL in it to get previous values...can u suggest me what to do to take the values..

How are you currently trying to get the value of the textarea?

[madhuriks]

already the existing values im taking...for that i used beans..

[acoder]

I meant with JavaScript.

[madhuriks]

no not by javascript..in java 'Beans' concept is there that i used..

In opposite to textboxes, Textareas don't have a value=... property. So your packDetails...-method (whatever that is and whatever this does) will have no effect.
This is the way how you assign a value to a text field:

<input type=text value="This is my text">

This is the way how you assign a value to a text box:

<textarea> This is my text </textarea>

This is truly a HTML/Javascript question, but not a java question, and should be moved to the appropriate forum.

By the way:
If you want to assign a value to a textarea in javascript, you can do it with

this.innerText="This is my text"

You can get it the same way you set it: with textAreaElement .innerText();

example:

<textarea onClick="alert(this.innerText)">
This is my text
</textarea>

If you click anywhere inside the text, it grabs the text from the text field and displays it in an alert box

Rather than innerText, use innerHTML (or standard equivalent).

To explain that a little more.

<textarea> does not have the HTML attribute value, but it has (like any form element) the JavaScript .value property. thus you can read/write like any other form element.
