Add to the entity command and also the org.springframework.roo.addon.entity.RooEntity annotation that can be used to set the name attribute of the javax.persistence.Entity annotation in the _Roo_Entity.aj file.
@RooEntity(entityName = "FullTime.Employment")
Would produce the following
declare @type: Employment: @Entity(name = "FullTime.Employment");
and also have correctly use the name when creating the finder methods.
