I use @Formula. It requires compile time instrumentation for lazy loading and will not load collections unless you use hibernate mapping files. It works fine with calculated properties and annotations as shown below. See: http://opensource.atlassian.com/projects/hibernate/browse/ANN-210 It works well and you can even use the properties in HQL. Example: private Double baseCostPerFt; | @Basic(fetch = FetchType.LAZY) | @Formula(value="( select v.basecostperft from v_item_calc v where v.id = id )") | public Double getBaseCostPerFt() { return baseCostPerFt; } | public void setBaseCostPerFt(Double baseCostPerFt) { this.baseCostPerFt = baseCostPerFt; } | HQL: select i from Item i where i.baseCostPerFt>10.59 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4109942#...
