Error in setting up postgres with wildfly

I've done the postgresql configuration:

C: \ wildfly-10.1.0.Final \ modules \ system \ layers \ base \ com \ postgresql \ main

I added the files: module.xml postgresql-9.4.1208.jre7.jar

The bank has version 9.6 and drive 9.4, can the problem be this?

Error:

Unexpected HTTP response: 500
