Install/Configure Oracle express

1. Oracle xe installer for linux (I don't care if you're running linux or not, this guy is going in a VM): http://www.oracle.com/technetwork/database/database-technologies/express-edition/downloads/index.html

1. sqlplus /nolog
2. connect sys as sysdba

Oracle JDBC Driver shenanigans

1. Download the JDBC driver: http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html
2. Here's where things get interesting. Apparently gradle can't load this jar from a flatFile repository. So the workaround is to create a local maven repository and load this 1 jar into it.
3. cd to the directory where the ojdbc jar is located
4. mvn install:install-file -Dfile=ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.4 -Dpackaging=jar
5. In the above command make sure to adjust the file, artifactId, and version to match the driver you downloaded.

spring-batch-jpa

This is an example project that contains everything needed to use Spring Batch 3 to read from a database via JPA and write to a database via JPA. There are also tests.

There were two blog entries associated with this project.

Spring Batch – reading and writing JPA

This is a simple Spring Batch project. This implementation will read from a database table and write to a database table via JPA.
