Well nandini,
UR question seems 2 b unclear...
through javascript u cannot connect 2 database
but using the above code in java ....u can get
connected ....but u say u dont want 2 use internet
than u can try for stand alone app. But still without
internet an intranet application can be built using
web interface.

Javascript is client side. You simply cannot connect jdbc using javascript u need to have some serverside technology! .anything like java, php coldfusion or somethinglike that .

hi ....
i ahve a project where i have to search for house ...
my website is in php and my database is in sql...and i have to use javascipt for search form can anybody help me and guide me how i can connect javascript with php and php to sql..
thanks

In PHP:

1) connect to the database, perform your query and store the search results in an array, e.g. $MyResults

2) write a loop-like-function, which puts your SQL results in a string, e.g. $gridData, formatted like this (example for an two-dimensional results array, containing ID's and names):

mydata_columns = [
"ID", "name"];

mydata_data = [
["1", "Pete"],
["2", "John"]
];

3. Define another string in PHP, e.g. $gridCode, containing the Javascript code to initialize the grid:

try {
var myGrid = new Active.Controls.Grid;
myGrid.name = 'myName';
myGrid.setRowCount(x); //let php replace x by the amount of rows
myGrid.setColumnCount(y); //let php replace y by the amount of columns
myGrid.setDataText(function(i, j){return mydata_data[i][j]});
myGrid.setColumnText(function(i){return mydata_columns[i]});

document.write(myGrid);
}
catch (error){
alert('Datagrid error: '+error.description);
}

4. Finally, echo both the string in your PHP file:

echo $gridData;
echo $gridCode;

5. Of course you should also add the links to the Grid Javascript and CSS files in the head of your document (adjust the path in href)

<!-- ActiveWidgets stylesheet and scripts -->
<link href="../../runtime/styles/xp/grid.css" rel="stylesheet" type="text/css" ></link>
<script src="../../runtime/lib/grid.js"></script>
<!-- ActiveWidgets PHP functions -->
