Can you please ask Teiid related question in Teiid forums? Can you move this, we will answer there. Quickly you either should be using OData, or would have generated a WAR file for above to work.
FYI Teiid forum is here: https://community.jboss.org/en/teiid?view=discussions
for some reason I can't choose that as destination when trying to move this thus please follow up in that forum directly.
The warning you are showing indicates that the call is being processed in Teiid. Was that from a browser call?
Can you provide more of the stacktrace, url and/or user sql that generated the warning?
