I am using google visualization API in JSF 2.0 application. I have made a
SqlDataSourceServlet which retrieves data from the remote database (Oracle
11g). But this servlet does not getting called, instead it gives the
following error on the error console.
Error: google.visualization.Query: Not Found [404] Source File:
Here is my code for Javascript calling the servlet :
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript"
src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
Array.prototype.reduce = undefined;
</script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['table']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(init);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function init() {
var query = new
google.visualization.Query('SqlDataSourceServlet');
query.send(handleQueryResponse);
}
// Handle the query response.
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' +
response.getDetailedMessage());
return;
}
// Draw the visualization.
var data = response.getDataTable();
var chart = new
google.visualization.Table(document.getElementById('chart_div'));
chart.draw(data, {width: 600, height: 150, is3D: true});
}
</script>
</head>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
</body>
</html>
The servlet mapping has also been correctly defined in web.xml.
Please help.
