Is there somewhere I can see the Java API for the Client model (if any)? Or how to create a Client from java? (my Peer Server is up and running)

Thanks,  
Marc

On the [Peer Language Support](https://docs.datomic.com/on-prem/languages.html) page it says that “The Java API gives Java users access to all the features of the Peer library” and that “The Clojure API is a functional projection of the Java API”.

I haven’t been able to find any mention of a Java API in the Cloud/Client documentation - is it so that the Clojure Client API is not a projection of a Java API? Or is there some business decision to not support the Client API being accessed from Java?

I hope I’m not jumping to conclusions, and that I have misunderstood something. I think I need some Java API to be able to adopt the [Scala Molecule](https://github.com/scalamolecule/molecule) library to Client/Cloud too and hope that you can help.

Thanks,  
Marc

Hi Marc,

The Java API is only available for Datomic On-Prem (Peer).

Accessing Datomic Cloud (via Clients) is only enabled through the Clojure Client API at this time.

Hi Marshall,

Thank you for clarifying!

If you decide to offer a Java Client API, I would be happy to make a Molecule Client adaption so that the Scala community could use this option too which I think would be cool.

Thanks,  
Marc

Hi Marc,

Thanks for the offer. I’ll definitely let you know if a Java Client is released.
