AccessPlusJava

I'm using Access 2007 as a database; some of the text fields contain Cyrillic characters. I have no trouble entering the Cyrillic characters into the Access 2007 database from the keyboard. But, when using JDBC in a Java program, and attempting to output the fields to a JTextField, all that is displayed is a series of question marks, e.g. ????????. According to Microsoft documentation, text fields in Access 2007 are stored as Unicode, and of course Java uses Unicode. So, what is going wrong? Why doesn't JDBC retrieve this data as Cyrillic characters? I set Unicode compression property on the text fields to NO, so that should not be the problem. Does anyone have a suggestion?
