"Name jdbc is not bound in this Context" when conncetiong from different pa

Question

Hi,
I'm just a beginner at this so I'll have to explain everything in details as i have no idea what could be wrong.
I have a working connection to mydatabase using the following method in a CommonMethods.java file in WEB-INF; this file belongs to the "package mrkt.app;" package.
    public Connection getDataBaseConnection() {
        Connection conn = null ;
        try {
            Context ctx = new InitialContext();
            DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/myproject");
            conn = ds.getConnection();
        } catch (Exception ex) {
            ex.printStackTrace();
        return conn ;
    }     I needed to create a new class in package "package mrkt.app.cat.shop;", in this new java file i need access to the database so i just copied and pasted the above code in the new java file, compiled it, put it in the "WEB-INF/classes/mrkt/app/cat/shop" folder, restarted tomcat to reload classes. The class is loaded successfully, but i always get the following error when calling the method(getShopsCount) using the connection function (getDatabaseConnection)

I have the same problem!
I created a couple of virtualhost on the same webapp like described here
http://www.onjava.com/pub/a/onjava/2003/06/25/tomcat_tips.html
the application works without problems if I point my browser to
http://ip_address/webapp
but, if I open http://www.myvirtualhost.com/ I get a
javax.servlet.ServletException: javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
I even defined the same datasource I use for the ip based browsing in the virtualhost datasources (through admin, without restarting tomcat) but I get the same exception... any suggestion?
thanks
