Problem with array ... help!

I have a table with column type int[], for example:
CREATE TABLE test (
id int[],
description text
);

When I try to get some data from this table (i.e. SELECT * FROM test),
JDBC create an exception:
"Class names may not have _ in them. You supplied {0}."
What does it mean ? Can anyone post example for working with arrays in
JDBC ? Please, help...

Thanks,

Alexey Slynko
