Change backend: Adapt jpaContext.xml for use with Hibernate and Oracle instead of MYSQL

Issue

I went through a Pluralsight video Spring with JPA and Hibernate video and got a HelloWorld "FitnessTracker" app to work against a local MySQL instance and now I am trying to convert it over to use an Oracle database.

I am getting the error show below. I copied the connection-specific information from a working program that used the SimpleJdbcInsert class (not Hibernate), in the event that this is helpful. That program was able to successfully connect to the database.

Here’s the error I am getting using Hibernate and Oracle:

Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver]

Here’s my jpaContext.xml file:

Solution

You should add oracle jdbc driver in your pom.xml.
I could not find it at maven central repository.

Maybe you need add it manually like described here:
http://www.mkyong.com/maven/how-to-add-oracle-jdbc-driver-in-your-maven-local-repository/

To install your Oracle jdbc driver, issue following command:

mvn install:install-file -Dfile={Path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

pom.xml

<!-- ORACLE database driver -->
<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0</version>
</dependency>

EDIT: or just add oracle jdbc lib in your project and references it.

<dependency>
    <groupId>sample</groupId>
    <artifactId>com.sample</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/custom_libs/yourJar.jar</systemPath>
</dependency>
