How to Re-Enable the JDBC-ODBC Bridge in Java 8?

JDBC-ODBC Bridge Removal in Java 8 and Mitigation Strategies

Starting with Java 8, the JDBC-ODBC Bridge has been deprecated. This has raised concerns regarding the connectivity to ODBC databases via JDBC.

JDBC-ODBC Bridge Unavailable in Java 8

In Java 8, the JDBC-ODBC Bridge is no longer available. This means that the common practice of using the following code will result in a ClassNotFoundException:

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Solution: Manually Installing JDBC-ODBC Bridge

To enable JDBC-ODBC Bridge functionality in Java 8, you can follow these steps:

1. Acquire Java Runtime Environment (JRE) 7.
2. Extract 'rt.jar' from JRE 7's 'lib' directory.
3. Copy the 'sunjdbc' and 'sunsecurityaction' folders from the extracted 'rt.jar'.
4. Create a JAR file named 'jdbc.jar' and compress the copied folders inside it.
5. Place 'jdbc.jar' in the 'lib' or 'libext' folder of your JDK 8 or JRE 8 installation.
6. Copy 'jdbcodbc.dll' from JRE 7's 'bin' directory to JRE 8's 'bin' directory.
7. Restart the Java Virtual Machine (JVM).

Conclusion

By following the steps outlined above, you can manually install the JDBC-ODBC Bridge in Java 8. This enables you to connect to ODBC databases using JDBC in Java 8 despite the removal of the bridge from the standard JDK distribution.
