jboss.jca.common.api.validator.ValidateException: IJ010075: The resource adapter metadata must contain either an outbound or inbound configuration

i'm trying to deploy a jdo resource adapter to wildfly 10 with this code: https://github.com/urbandroid/datanucleus-jca-adapter java:/TestDS datasource deployed to server resource adapter must use this datasource.

I'm not sure what to put on inbound or outbound section it is a jdo adapter which is a ORM tool which needs to stand between my code and datasource.

I'm getting error below can you help me?

I was adding ra.xml to jars META-INF directory instead of rar META-INF directory. Adding to rar's META-INF directory solved the problem.
