{
super(objectDao);
}
#Override
#Path("/getAppVersions")
#GET
#UnitOfWork
public String getAllRecords(#Context HttpServletRequest req, #QueryParam("callback") String callback) throws JsonProcessingException
{
return super.getAllRecords(req, callback);
}
}
VersionTable.java
#Entity(name = "Versions")
#Table(name = "Versions")
#NamedQueries({ #NamedQuery(name = QueryNames.QUERY_VERSION_GET_ALL, query = "select c from Versions c"), })
public class VersionTable extends baseDataBase implements Serializable
{

I think you need a no arg constructor for your VersionResource class, but if you really need an argument the value should be passed by injection (see: https://eclipse-ee4j.github.io/jersey.github.io/documentation/latest/jaxrs-resources.html#d0e2692)
