Subject: JNDI: datasource is null

my servlet I have the following lines...

> Context initCtx = new InitialContext();
> Context envCtx = (Context) initCtx.lookup("java:comp/env");
> DataSource ds = (DataSource) envCtx.lookup("jdbc/Support");
> Connection conn = ds.getConnection();

> The problem is that the envCtx.lookup is returning null so
ds.getConnection() throws a NullPointerException every time. I'm not getting
any other errors. I have been able to access this database with these
parameters from a servlet (without JNDI) so I know that it *can* work. I'm
sure I'm missing something simple, but I can't figure out what it is. I've
searched the archives and have seen this problem described, but no solution.
I've tried changing "driverName" to "url" as has been suggested, but that
made no difference. I'd appreciate any help in getting this working. Please
let me know if more info is needed. (Config info is below.)
