If they want Json support for JSR-353 types, one is already published. https://mvnrepository.com/artifact/com.mopano/hibernate-json-contributor
If they want it for a non-standard API, they are free to use it's source as a base. License permits it. They will need 5.2.10 if they need to bind a JsonArray as a native query parameter. I've tried making a module that uses PgObject, but that runs into very nasty classloader problems in Apache Tomcat. A work-around should be possible with reflection, but it isn't worth it for things where [sg]etString works. _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
