title: Deployment of Resource Adapter on Wildfly WFLYJCA0046 / IJ020066
body: <p>Based on the Trading Connector example from the JEE 7 Tutorials, I've tried to create my own Resource adapter. It worked fine with glassfish.</p>
  
  <p>I'm trying to deploy my .EAR to a wildfly 10. It doesn't work, and is throwing the message below. I am kinda lost on where to start looking, as the only mention of the error code is in the source code of wildfly itself and I'd rather not read all the Wildfly code now (but I'm at it).</p>
  
  <p>The Resource Adapter is part of a .ear file, in that ear file I have an ejb project that is client to this RA, in order for the ejb to compile I create a ra-lib.jar alongside the rar that contains only the entries from the api package.</p>

  <p>I can see no reason that a ClassLoader that can see the ConnectionFactoryImpl can not also see the interface. I had the interface in a different jar earlier (so that I don't need to produce a jar from the rar for the clients) and that yielded the same error.</p>
  
  <p>I've kept this short, so please ask when something is missing, I will add it promptly.</p>
