Using PreparedStatement to call a function

HI all.

I have a function called:

dbcmp(
t varchar,
p varchar[],
c varchar[],
n INTEGER
) RETURNS SETOF dbcmp_t
...

Today, I call my function like this:

String sql = "select * from dbcmp('" + t + "','" + p + "','" + "'," + n + ")";
Statement stmt = con.createStatement(sql);
ResultSet rs = stmt.executeQuery();
...

I want to transform my code to use PreparedStatement like this:

String sql = "select * from dbcmp(?, ?, ?, ?)";
PreparedStatement ps = con.preparedStatement(sql);
ps.setString(1, t);
ps.setArray(2, p);
ps.setArray(3, c);
ps.setInt(4, n);

But I don´t know how to create an Array object to use the set.

Can anyone help me? :-)

Thanks in advance.
