I used the Apache Commons builder classes. I generally try for equality of significant properties in POJOs and so far it seems to work fine.Developer Dudehttp://www.blogger.com/profile/01475883843077887466noreply@blogger.comtag:blogger.com,1999:blog-2260432230294560411.post-55855277899621308732009-10-13T08:37:48.573-07:002009-10-13T08:37:48.573-07:00nice post!!! and very usefull!!Victor Panizzahttp://www.blogger.com/profile/13791852820572777518noreply@blogger.com
