Pas de classe Exception Found : java.lang.ClassNotFoundException : com.mysql.jdbc.Driver ? -Débordement de pile

com.mysql.jdbc.Driver not found with mysql connector in buildpath



I'm working on connecting MySQL database to a Java program. When I run my program I am getting this error



Class Not Found Exception: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver



for this line



try{ Class.forName("com.mysql.jdbc.Driver").newInstance();



So, what's the problem? I'm placing the connector in the project's file.. Is the correct or should it be in another location?


OS Windows XP, Eclipse 4.0, mysql connector 5.1.22




JAR file need to add to project class path.


First Right click on you Eclipse Project,  Project --> Build Path --> Configure Build Path. Under Libraries tab, click Add Jars or "Add External JARs".



You don't even need that line of code, any time in the last five years or so. Just delete it,




The jar file should be in your classpath. If you have created the project through an IDE, make sure you add the jar in your build path.




You have to include the connector jar file in your project's build path. In eclipse project properties dialog, go to "Java Build Path" and add the jar file in "Libraries" tab




the jar should be included in your classpath. In your IDE, configure your build path and add the required jar in your libraries section.
