I can't register Mysql JDBC driver in my desktop APP
I download mysql-connector-java-5.1.16.zip
Unzip mysql-connector-java-5.1.16-bin.jar and put it into lib folder in my app
Add this jar file into Build Path in Eclipse
But Class.forName("com.mysql.jdbc.Driver") throws ClassNotFoundException
Whats wrong?
try this:
public static void main(String[] args) throws Exception {
Class.forName("com.mysql.jdbc.Driver");
}
The issue is that Class.forName(String)
throws an checked exception. With a checked exception, you can either:
Here is an example of catching the exception:
public static void main(String[] args) throws Exception {
try {
Class.forName("com.mysql.jdbc.Driver");
} catch(ClassNotFoundException e) {
//do some exception handling
}
}
In your lib directory,
Also, if you are running JDBC 4.0 compatible driver you no longer need to automatically load your driver. According to JDBC 4.0 specification, section 3.1 under Automatic loading of java.sql.Driver
says
DriverManager.getConnection
has been modified to utilize the Java SE Service Provider mechanism to automatically load JDBC Drivers. This removes the need to invokeClass.forName
.
You could double check that the jar is really in the Eclipse build path.
Project Properties > Java Build Path > Libraries > Add JARS
Try a: Project > Clean
on the Project menu in Eclipse.
