Am pretty new to OData. Per my internet reading what I've gathered is Apache Olingo is better (vs OData4j) for Java implementation of OData service and OData consumer.

Have a good one.
Thanks.

If you want to create an OData service that uses JPA this is a good resource: OData JPA Web App. Also this one is helpful Olingo OData with MySQL.
