Configure Quercus for MSSQL

Question

Right now I have tomcat8 with Quercus 4.0. and running up. I'm trying to configure a MSSQL db connection to use from PHP.

On doing:

<?php
$pdo = new PDO("java:jdbc/test");
?>

I got:

C:\java\tomcat8\webapps\php1\info.php:2: Fatal Error: 'java:jdbc/test' is an unknown PDO JNDI data source. 

Probably there is a problem with the config.

web.xml
