Anyone has an idea as to why the jar can't be found?
The jar can't be found due to license constraints.
Is my POM.xml not setup properly?
No it isn't, but adding to your pom the dependency:
<dependency>
<groupId>ojdbc</groupId>
<artifactId>ojdbc</artifactId>
<version>14</version>
</dependency>
you are able to download only the ojdbc14
pom because it has not a license limitation about distribution.
In order to make the above dependency works the jar has to be manually installed into your local Maven repository, without violating the license, by running:
mvn install:install-file -Dfile={Path_to_your_ojdbc.jar} -DgroupId=ojdbc
-DartifactId=ojdbc -Dversion=14 -Dpackaging=jar
eventually changing to the appropriate version number in -Dversion attribute, as correctly suggested by user1570577.
