JDBC Driver class not found: com.mysql.jdbc.Driver

Question

I am developing a web application using maven spring and hibernate and I need to create schema using hibernate for which I had the following in my pom.xml to connect to MySQL 5.5 database.

    <!-- MySql 5.5 Connector -->   
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.15</version>
    </dependency>

This imported mysql-connector-java-5.1.15.jar in my Libraries under Maven Dependencies but when I try to connect to database it gives me Exception in thread "main" org.hibernate.HibernateException: JDBC Driver class not found: com.mysql.jdbc.Driver.

I have done this like gazillions of times, but I did it when I din't used to use Maven to manage my dependencies and build the project. I just used to have it the same jar file in the lib folder of a Dynamic Web Project in Eclipse IDE.

Could someone tell me what am I missing here and what else I need to have this jar in my build path?

Thanks.

Answer 1

To start with, the jar that I need to connect to MySQL 5.5 should have been mysql-connector-java-5.1.15-bin.jar but not mysql-connector-java-5.1.15.jar. Secondly, this jar is not available in maven repository so I needed to manually add it to my local maven repository and then added it as a dependency in my pom.xml.

Adding mysql-connector-java-5.1.15-bin.jar to the local maven repository by

mvn install:install-file -Dfile=C:\Libraries\mysql-connector-java-5.1.15-bin\mysql-connector-java-5.1.15-bin.jar -DgroupId=mysql -DartifactId=mysql-connector-java -Dversion=5.1.15-bin -Dpackaging=jar

and then adding the following dependency to pom.xml of the project.

    <!-- MySql 5.5 Connector -->   
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.15-bin</version>
    </dependency> 

Answer 2

Unzip your generated JAR file. There is a folder WEB-INF in. Then check if mysql-connector-java-5.1.15.jar exists in this WEB-INF/lib.

Thanks for the answers above - just a comment for NetBeans users: (names to be replaced with your versions)

1. The mysql JAR can be downloaded here
2. mvn executable can be found at c:\Program Files\NetBeans 7.2.1\java\maven\bin
3. run set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_10
4. Then the above command would work: mvn install:install-file -Dfile=mysql-connector-java-5.1.15-bin.jar -DgroupId=mysql -DartifactId=mysql-connector-java -Dversion=5.1.15-bin -Dpackaging=jar
5. installed package could be found in m2 repository in your home folder

Answer 4

My working solution

 <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.18</version>
</dependency>

adding above dependency to pom.xml works for me...
