Two questions:
Class.forName(....) and DriverManager.getConnection(....), what driver and URL should you use?
There are two techniques available for connecting to a data source using JDBC. First, if your program will talk to an ODBC
data source, you can use the JDBC-ODBC bridge included with your JDK. In the case of Sun, you would use sun.jdbc.odbc.JbdcOdbcDriver.
Specifically, using Class.forName:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
or the command line:
java -Djdbc.drivers=sun.jdbc.odbc.JdbcOdbcDriver <program name>
Second, you can connect to your data source through a third-party, vendor-specific bridge. In the case of a third party driver, you simply substitute that driver for the JDBC-ODBC bridge driver.
See the Resources section below for a link to Sun's database of available drivers.
Once you have a driver loaded and your data source set up, getting a connection is a simple matter of feeding the correct
URL, name, and password to the getConnection() method.
A JDBC URL takes the following form:
jdbc:<subprotocol>:<subname>
In the case of Microsoft Access and the ODBC bridge, it would take the form:
jdbc:odbc:<NAME>
where <NAME> is the name that you gave the data source when you set it up.
As an aside for those using other drivers, <subprotocol> is the name of the connectivity mechanism used by the driver.
In my answer, I've assumed quite a bit of JDBC knowledge. If you're completely new to JDBC, or even if you just need to brush up your skills a bit, head on over to the JDBC Short Course (see Resources), an excellent training course that will get you up to speed quickly.

second thatBy Anonymous on September 17, 2009, 4:05 pmI second this question. I am guessing since an image is simply a binary file, I would be trying to retrieve binary data but I am still unsure.
