In the Spring framework, how is an Oracle data-source configured?
Note you may want to add to the above that the Oracle driver does not have an open source licence so it will not be in the Maven central repository. You'll have to add it to your local repo.
To do this: Get the driver you want from: http://www.oracle.com/
Or you can get it from your oracle installation: {ORACLE_HOME}\jdbc\lib\ojdbc6.jar
Then run the following maven command:
mvn install:install-file -Dfile={Path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar
This should install it in your local repository so when you reference it as user640378 states above it should work correctly.
