Install/Configure Oracle express
- 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
sqlplus /nolog
connect sys as sysdba
Oracle JDBC Driver shenanigans
- Download the JDBC driver: http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html
- Here's where things get interesting. Apparently
gradle
can't load this jar from aflatFile
repository. So the workaround is to create a local maven repository and load this 1 jar into it. cd
to the directory where the ojdbc jar is locatedmvn install:install-file -Dfile=ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.4 -Dpackaging=jar
- In the above command make sure to adjust the file, artifactId, and version to match the driver you downloaded.

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.
