[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Hi there,
i've got a problem to connect me with the odbc driver manager in my java application. I get the following Exception, while connection to the database: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

On my system, i have a 64 bit OS (Windows Server Edition 2008), a 64 Bit JVM and Access 2010, also 64 Bit.
The ODBC-Driver is also installed correctly in the driver manager as 64 Bit version.

In my Java Application, I try to start a connection with the following lines of code:
Driver d = (Driver)Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance(); Connection c = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=c:/tech97.mdb"); Here, I get the called Exception.
But I really don't know why. I also tried to install the 64Bit version of the "Microsoft Access Database Engine 2010 Redistributable" http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=13255 , but it didn't work out either.


Would be happy, if someone could help me out!

Best Regards,
Martin
