Auto generating entity beans

sarabjit Aug 4, 2009 3:46 AM

Hey Everyone,

Am a newbie to EJB and EJB3. Am using postgres and was wondering if there is anyway i can autogenerate entity beans given a schema.

Thanks for your help in advance.

As far as i know, there is no spec compliant way of doing this. Each persistence provider (Hibernate, TopLink etc...) have their custom ways for reverse engineering. See this Hibernate documentation https://www.hibernate.org/255.html

Hi sarabjit,

as far as I know, Eclipse + WebToolsPlatform-plugin + Data Tools Platform plugin provide a way to generate entities from a schema. But I never used this, so I cannot help you much further.

Best regards

Wolfgang

Thanks guys, just to answer to that. I used Hibernate tools. It works pretty pretty well and is easy to use. https://www.hibernate.org/hib_docs/tools/reference/en/html/plugins.html gives you more info.
