Establishing connection from java to access 2010 64bit

问题

After going through several tutorials and blog posts, i have unsuccessfully tried to set up a connection from java to a microsoft access database. my system specifications are

win 7 [64 bit] odbcad32.ese [64 bit] access 2010 [64 bit] jre6 [64 bit]

the code that i wrote for establishing a connection :

        public Connection makeConn() throws ClassNotFoundException, SQLException
        {
           Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           conn = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=C:\\Users\\ARIFAH\\Desktop\\sampleDb.mdb");

           return conn;
        }

in the data source [odbc]---[located at path %windir%\system32\odbcad32.exe]

i performed the following task

USER DSN TAB ADD->Microsoft Access Driver (*.mdb, *.accdb ) [file ACEODBC.dll] ->Finish
Data Source Name: TestDriver ; Description: test driver for access 2010 64 bit ;
DataBase->select ->browse: C:\Users\ARIFAH\Desktop\sampleDb.mdb -> ok
apply
ok

now when i try to run my application, this is the error that i m getting,

    java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Could not find file '(unknown)'.

Can somebody help with it?

回答1:

Did you try changing your connection string to:

jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\\Users\\ARIFAH\\Desktop\\sampleDb.mdb

That appears to be the difference between the 32 and 64 bit versions of the driver. I am able to connect using that string with the same environment.

(Now I just have to figure out what's happening with the "java.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid string or buffer length" error I'm getting...)
