The log shows that this is a database problem, probably caused by OpenJPA. I suspect that a wrong version of OpenJPA is used in Websphere. This can be detected in the log, for instance if you see a message in the log such as

INFO [server.startup : 2] openjpa.Runtime - Starting OpenJPA 2.x

As of MobileFirst 7.0 and earlier, the correct OpenJPA version must be 1.2.2, not 2.x (2.2.3 or similar).

This error typically occurs if the parentLast classloader policy is not set for the applicationcenter.war. For WAS Full Profile, see step 5 here. For WAS Liberty Profile, see the element <classloader delegation="parentLast"> here.
