EclipseLink not working with Latest MongoDB [message #1710830]

I'm using EclipseLink 2.6.1RC and Mongo 3.1.0. I've also tried with EclipseLink 2.5.2 and get the same issue.

I get a NoSuchMethodError when trying to create an EntityManager.

Any idea what I'm doing wrong?

Thank you!

Eclipse Link's MongoDB support depends on a quite old version of the MongoDB Java driver: 2.7.3 to be exact. The 3.0 driver, which you are trying to use, made several changes that broke binary compatibility, hence the major release bump. Until Eclipse Link is updated to support the 3.0 driver, please stick with a 2.x release of the Java driver. The latest is currently 2.13.3, which is binary compatible with 2.7.3.

The dependency is:

<dependency org="org.mongodb" name="mongo-java-driver" rev="2.13.3"/>

Hi Jeff,

Thanks so much for taking the time to respond. I appreciate it. This helps knowing that I'm not doing something wrong.

This presents a problem for me as the larger application that I'm part of is using the latest Mongo driver so it's hard for me to build my part with the older driver.

Have you heard that the EclipseLink folks are working on this?

Thanks,
John

Are you aware of a different JPA package that works with the latest MongoDB driver? I really like EclipseLink, but I need to make my code work with the latest driver.
