DataSource from Context files - doesn't work

[Mighty Tornado]

Hi I placed the following in context.xml in META-INF.
But the result set is null, what's wrong with my set up?Can anybody please
advise?

<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Resource
    auth="Container"
    description="DB Connection"
    name="jdbc/vhousehold"
    type="javax.sql.DataSource"
    password="vhousehold"
    driverClassName="com.mysql.jdbc.Driver"
    maxIdle="2"
    maxWait="5000"
    validationQuery="select * from family_member;"
    username="vhousehold"
    url="jdbc:mysql://localhost:3306/vhousehold"
    maxActive="4"/>
</Context>

Thanks,

Ramy.
