java.lang.ClassNotFoundException: com.mysql.jdbc.Driver in Eclipse

Question

What is wrong with the code there are lots of error while debugging. I am writing a code for a singleton class to connect with the database mysql.

Here is my code

Answer 1

It seems the mysql connectivity library is not included in the project. Solve the problem following one of the proposed solutions:

• MAVEN PROJECTS SOLUTION

Add the mysql-connector dependency to the pom.xml project file:

    mysql
    mysql-connector-java
    5.1.39

Here you are all the versions: https://mvnrepository.com/artifact/mysql/mysql-connector-java

• ALL PROJECTS SOLUTION

Add the jar library manually to the project.

Right Click the project -- > build path -- > configure build path

In Libraries Tab press Add External Jar and Select your jar.

You can find zip for mysql-connector here

• Explanation:

When building the project, java throws you an exception because a file (the com.mysql.jdbc.Driver class) from the mysql connectivity library is not found. The solution is adding the library to the project, and java will find the com.mysql.jdbc.Driver
