title: Synchronize between database and Hibernate Mapping Files and POJOs
body: <p>I have a schema in MySQL, I used Netbeans to generate the POJOs from it. Then, I upgrade my app and modify the schema (big modification), now I want to sync my POJOs up-to-date to my schema. Please tell me how to do it, I cant re-generated the POJOs because when programming my app, I have modified the POJOs a lot and manual-sync may cause a lot of error.</p>
  
  <p>Yeah, I know Bedwyr has asked this question last year. But now, Hibernate framework has upgraded many times. So maybe it has supported this feature. If it does, please tell me how to use.
  Many thanks!</p>
