How to connect to Microsoft Access or Microsoft Excel from Java. Introduction JDBC is a Java application programming interface ( API) that connects Java to relational databases (and other tabular data, such as spreadsheets and flat files). To interact with a database, a Java application uses a JDBC driver. A JDBC driver implements the JDBC API for a particular database. Microsoft do not produce a JDBC driver for Jet (the underlying database engine for the Microsoft Office product suite) or Jet's successors the Office Access Connectivity Engine and the Access Database Engine. However, Microsoft do produce an ODBC driver for the Office suite. ( ODBC is another data access technology, the Microsoft implementation of which is included with Windows.) To provide a JDBC interface to Office applications via this native Microsoft interface, a JDBC driver must be able to convert JDBC calls to ODBC calls. As far as the Java application is concerned, it is using a normal JDBC driver. As far as the Office application is concerned, it is being accessed via the normal ODBC driver. The Easysoft JDBC- Access Driver is a JDBC driver for Access that uses the Java Native Interface ( JNI) to communicate with the Access ODBC driver library. Because this ODBC driver library also supports Excel, the Easysoft JDBC- Access Driver also provides JDBC access to Excel. You can use the Easysoft JDBC- Access Driver to connect Java applications, servlet/ Java Server Pages ( JSP) engines, integrated development environments ( IDE) and application servers with Access and Excel. The Easysoft JDBC- Access Driver has both a Java component and a native Windows component, which is used to communicate with the Microsoft ODBC driver. By default, Java applets cannot load native code libraries; the Java security mechanism prevents this because it cannot police what happens at native code level. To use the Easysoft JDBC- Access.
I want connect my MS acces file with java gui program,but I have problem with connection. I have Windows 7 64b, and ms office 2007. When I opened the ODBC driver manager in the control panel I havent found any driver for Microsoft Access (maybe when I started the ODBC is started running the 64bit ODBC, now I think is running the 32bit ODBC. I read this and I make it : jdbc-odbc connection for window 7 64 bit machine. 1. right click Data source ( ODBC).go to properties change the folloing thing target [ % System Root%\ Sys WOW64\odbcad32.exe ] start in : [ % System Root%\ System32 ] press enter and continue as admin source: source link ) Now when I start in conctrol pannel the ODBC I can see the driver screenshoot My program code( I tried two ways but i have same error public void Connect try Class.for Name( sun.jdbc.odbc.

In 32-bit Java, the technique for connecting to a Microsoft Access file via JDBC connection is well-known and available as part of the Sun JDK. There are a number of errors, though, if you attempt to use a 64-bit version of Java that are not as well documented. This article points out some of those issues and a working strategy for how to successfully connect to a Microsoft Access file via JDBC in 64-bit Java. 1. Review of the 32-bit Connection Strategy The well-known syntax for connecting to an Microsoft Access file via JDBC is as follows: final String file Name = ; Connection con = null; try Class.for Name( sun.jdbc.odbc. Jdbc Odbc Driver String url = jdbc:odbc: Driver= Microsoft Access Driver.mdb) ; DBQ= +file Name; con = Driver Manager.get Connection(url, catch ( Exception e) / Handle exceptions. finally try if(con!=null) con.close catch ( Exception e) If you are using the Sun JDK, then the driver will be available in the classpath automatically. Notice, I make sure to close my connection object in a finally block as all good JDBC developers know to do. 2. Errors in the 64-bit World Attempting to run the proceeding code returns the following error when using a 64-bit JDK: [ Microsoft][ ODBC Driver Manager] Data source name not found and no default driver specified If you would prefer to stick with the 32-bit version of the driver, there are two options available: Use the 64-bit Java installation but run java.exe with the “- D32” flag. Use a 32-bit Java installation Both of these solutions limit the amount of memory a Java application can use. 3. Adapting JDBC to 64-bit Java If you would prefer to use the 64-bit Java, there is a solution, although for some users this may require removing Microsoft Office. Step 1: Download the Microsoft Access Database Engine 2010 Redistributable, specifically the Access Database Engine_x64.exe file. Step 2.
