Problems with "order by clause"

Hello to everybody,

I have a little problem concerning the "ORDER BY" clause.
Consider a table "test" having one text field "val" with the following
entries:

tralala
Tralala
tralal

Now, I want to execute the following query via JDBC:
    SELECT * FROM test ORDER BY val DESC;
When using JDBC with Oracle or Sapdb I get the following result:

tralala
tralal
Tralala

(correct lexicographic order as expected by Java)

Now, using PostgreSQL (7.1.3 with JDBC driver 7.2) the result is:

Tralala
tralala
tralal

(lexicographic order as implemented in PostgreSQL)

Any ideas what's going on there? 

Thanks in advance,
