hop of those help? The mappedBy attribute is referencing customer while the property is mCustomer, hence the error message. So either change your mapping into:
code :
/** The collection of stores. */
@OneToMany(mappedBy = "mCustomer", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Collection<Store> stores;
: mappedBy reference an unknown target entity property

: mappedBy reference an unknown target entity property

wish of those help Change mappedBy value, so that it refers the manufacturer property on the @ManyToOne side of the association:
code :
@OneToMany(fetch=FetchType.LAZY,mappedBy="manufacturer")
public Set<MobileDTO> getMobileDTOs() {
    return mobileDTOs;
}
I'm getting a mappedBy reference an unknown target entity property and I'm just not seeing the error

should help you out Fix your property camel-case naming.
If your getter is getEventType() then mappedBy attribute should be eventType (similar problem is in eventmasters => eventMasters).

With these it helps I dont know where actually im going wrong can someone help to get rid of this error. , mappedby must have a valid property name as value:
code :
@OneToMany(mappedBy = "niftyDTO", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<NiftyDataDTO> niftyDataDTO;

This might help you The mappedBy property is trying to reference an invalid property "sgpersona" in the class "Sgordcompra". The OneToMany mapping should be done as follows:
