异常：ClassNotFoundException：com.mysql.jdbc.Driver

Question

I am doing a simple JSP program to connect with MySQL DB. But it's showing the Exception like this. I am using Java version 1.6 and MySQL -connector 5.1.20. I have placed this connector (.jar) file in lib/ext directory of JAVA_HOME. I have set the CLASSPATH also to the value upto connector (.JAR) file. Still, I get the same Exception.

I have searched for this. I did all the things suggested by them. But I didn't found any results.

Please help me.

Answer 1

Place the connector jar in the TOMCAT_HOME/lib folder of your tomcat installation. It should work.

Answer 2

如果您使用的是Netbeans，则右键单击您的项目，选择“添加库”，然后选择MySQL JDBC驱动程序并保存。
