Re: Modifying classes generated by the Restful webservices Wizard

[tdeit62]

I generally make a copy of each Facade class (and entity class if I’ve made changes to the named queries etc) from the previous generation before using the wizard to recreate the classes. Then it’s simply a matter of copying across any manual changes I made to the new entity classes and deleting the previous generation. Diff is a great help there.

Subject: [nbj2ee] Modifying classes generated by the Restful webservices Wizard


Hi,


suppose I create some entities + session beans with the 'Restful web services from database'

wizard which works fine.



For example:

database table: 'User' => wizard creates: entity: User.java + session bean: UserFacadeREST.java



I want to make some changes to these classes ( e.g. add some named queries to User.java

and respective methods in Facade which use these queries ). Now when the database

table is extended and the classes have to be re-created the changes are lost.



So I have to do something like create my own 'MyUserFacadeREST' subclass of

UserFacadeREST to implement my modifications. But session beans are not

allowed to extend other session beans...



Maybe it's more a 'session bean' question but I think everyone using this

generator will also have this problem.



So how can this be handled? Is there already some best practice?

Hi Jan,

You didn't mention if you are using JAX-RS for your RESTful services or something else.

.. I just saw that answering like I just did (@Tony,@Steven..) doesn't make lots of sense so
I repost this answer to have it at the correct position:


Hi Steven,


I use JAX-RS (Jersey) for the REST services which produce both xml and json. I'm just reading something about EJB and the @Inheritance annotation but don't know yet if that's the way to go.. Does jax-rs itself offer something?

[Jan Rosendahl]

Ok, so now I got half the way of it:

1) Netbeans generates User.java and UserFacadeREST.java ( session bean )
2) I want to have some special behavior in UserFacadeREST

Last update for today:

The 'Restful Webservices from Database' wizard is so kind to merge the
