I have a JUnit class which imports my DAO class.
In one of my JUNIT testcase. I want to call a method from DAO class, that connects to database. i.e I want to test a connection to database.

/* DAO class connection that is used to connect to database by reading datasource files stored in JBOSS applicatin server */
private Connection connectToDatabase(String name) throws DaoException, SQLException{
        Context ctx = null;
        DataSource ds = null;
        try{
            ctx = new InitialContext();
            ds = (DataSource) ctx.lookup("java:" + name + "-ds");
        }catch(Exception e){
            throw new ErpProxyDaoException("Thrown NamingException -- ", e);
        }

        return ds.getConnection();
}

I’ve connected to Jboss4.3 server using MyEclipse, and ran the server using default configruation. The server started with out any hitch.

But when I try to run Junit test it displays me a error as such

1) Can anyone explain me what am I doing wrong here?
2) Is the JUnit/MyEclipse looking at the Jboss sever to read the datasource files? If not, how should I make them look at those files?
3) Can any one give me a (link to ) tutorialthat explains how to test database application using Myclipse, JUNit and Jboss?
Please any help is appreciated.
