Java Database Connectivity (JDBC)

Hello

I've met a little problem. Need to write java object to oracle object, but object contains an java array. How to cast it to java.sql.Array? Thought about oarcle.sql.ARRAY, but Connection object is needed for that and i have not.

example

public class test implements SQLData {
long n;
Object[] troubleArray; // need to write
...............
public void writeSQL(SQLOutput stream) throws SQLException {
stream.writeLong(n.longValue());
stream.writeArray(...); // input parameter is java.sql.Array
}
..............
}

HOW TO DO THAT??? Please help.
