Hello there internet community,
So I went into JAVA and started test things localy on my WildFly 8. Everything is OK with maven web projects, looks and works good. Now I decided to go to openshift as the first choice of free cloud for JAVA. I managed to do all needed to get my eclipse and enviorment to work/upload/update server. Then I decided to add MySQL with JPA/Hibernate and localy everything is OK. BUT, when I upload to openshift I get the following error:

as you can see the error comes from

(alot of text has been outputed, so quick reminder: localy eveyrthing works like a charm)
So I went with "rhc ssh -a appname" and checked that in wildfly/standalone/deployments/ROOT.war IS compiled in standalone WAR file, while in local system the whole project is folder based - it's not compiled to WAR. That's NOT especialy a bad thing, but the point is that when I unziped the WAR, I checked if folder structure is the same as local folder structure. It seems that it's NOT. There is not META-INF in ROOT.war/WEB-INF/classes where persistence.xml actually stands ... that was a strange one! What I did is to add @PersistenceContext(unitName="ROOT") to em injection point, manualy create that folder (META-INF), manualy upload my persistence.xml from local computer, and rename ROOT.war.failed to ROOT.war.dodeply to re-deploy, and it worked. But then I made some changes to the code localy, again it worked like a charm, published to openshift thru eclipse and still openshift complied my ROOT.war to webarch and META-INF and standalone.xml are nowhere to be found which yet leaded to the same error. So my question is: what am I doing wrong if everything works great localy, and doesn't when is uploaded to openshift? Thanks in advance for your time.
PS.: English is not my native sorry for any errors. I hope everything is readable and understandable. Any more additional info I will provide on demand.
