    Default Problems about connection to a database

    I've imported a dynamic projects which connects to an old Cloudscape v5.1 database. It works fine, that means the different .jsp pages connect to the database and can work with it.
    Now, I want to set up a new dynamic web project and work with the same database. I'm trying to set up a connection (through a datasource), but I always get an error!

    Here's the code:
    javax.naming.InitialContext ctx = new javax.naming.InitialContext();
    ds = (javax.sql.DataSource)ctx.lookup("java:comp/env/" + datasourceRef);
    con = ds.getConnection();

    and the error I get:
    Connection exception: Name "comp/env/ClipsAndTacks" not found in context "java:".
    Exception thrown: null

    I have to admit, that I don't understand anything from the first two rows of the code.
    Can someone help/explain me?
    I would really appreciate every answer!
    Thanks a lot!

    You have to learn some basic JNDI
    and find a way to configure your environment.

    Here is how it is done with Tomcat :
