ShowJdbcDrivers.java - ojdbc Oracle Driver Example
How to verify if ojdbc Oracle Driver is loaded corrected from the classpath? I want to see a Java program example.
✍: FYIcenter.com
Here is an example program, ShowJdbcDrivers.java, that can be used to verify if ojdbc Oracle Driver is loaded corrected from the classpath or not:
// Copyright (c) FYIcenter.com import java.sql.DriverManager; import java.sql.Driver; import java.util.Enumeration; // Example show all JDBC drivers loaded in the classpath public class ShowJdbcDrivers { public static void main(String [] args) throws Exception { System.out.println("Loaded JDBC driver classes:"); for (Enumeration<Driver> drivers=DriverManager.getDrivers(); drivers.hasMoreElements(); ) { System.out.println(drivers.nextElement().getClass().getName()); } } }
You can compile and run the above example in a command window. You should see ojdbc Oracle Driver class listed in the output:
C:\fyicenter>\local\jdk-1.8.0\bin\javac ShowJdbcDrivers.java C:\fyicenter>\local\jdk-1.8.0\bin\java -cp .;\fyicenter\Oracle-12.2.0.1\ojdbc8.jar ShowJdbcDrivers Loaded JDBC driver classes: oracle.jdbc.OracleDriver
If you run the example again with a typo in the classpath, you will not see the ojdbc Oracle Driver class in the output:
C:\fyicenter>\local\jdk-1.8.0\bin\java -cp .;\fyicenter\Oracle-12.2.0.1\ojdbc18.jar ShowJdbcDrivers Loaded JDBC driver classes:
⇒ ojdbc Oracle Driver Connection URL String
⇐ ojdbc.jar in Java Database Connection Architecture
