JDBC: Selecting Dates

I'm having problems using date ranges as a selection criteria.

I'm communicating with access via the JDBC-ODBC bridge.

The sample SQL statement is:
SELECT otherCol, dateCol FROM table WHERE dateCol = '01/01/99'
I'm actually selecting a date range using something like:
SELECT otherCol, dateCol FROM table WHERE dateCol BETWEEN '01/01/99' AND '12/31/99'
but the first example doesnt work either (and its the simplest case).  
Ive tried formating the date any number of ways. (19990101, 1/1/99, 01/01/1999, etc)
The column in the Access database is a Date/Time (with no time).  An example field is displayed in Access as 1/1/99.

Error Message:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.

Code:
...
Statement stmt = con.createStatement();
String queryString= "SELECT col1, dateCol FROM table WHERE dateCol = '01/01/99'";
ResultSet rs= stmt.executeQuery(queryString);
...

What is really interesting is Ive tried using:
SELECT otherCol, dateCol FROM table WHERE dateCol = 01/01/99
(no single quotes)
and I don't get any error messages.  However, I dont get any records either.  Ive looked at a number of SQL resources and they all say to put dates in single quotes.  Does the driver somehow think that the date column is a Number instead of Date/Time?
Is there anything Im doing wrong?

Works good.

Its strange that all the online references I've found use ' to wrap dates (like strings).

Is there an online version of the reference you mentioned or any other good reference?

If you have a URL handy that would be great so I don't have to bother you guys with these slightly offtopic postings.

If not thats ok.  You answered my question.

Thanks
