I was accessing Access DB without any problem until now and I have this error.
java.sql.SQLException: Failed to load database MSOData! For more information, please use SQLException.getNextException()
It looks like this driver acts strangely....
catch( SQLException sqle )
I guess that your MSOData databse is an encrypted mdb database, or HXTT Access failed to check the integrality of that database so it refused to load it.
