Description Mark Dey 2006-12-01 20:32:48 UTC
Creator 2 provides the ability to visually bind an EJB to a web UI component by
dragging and dropping an iconified representation of the EJB onto the designer.
This capability needs to be made available in the visual web project in NetBeans 6.

hi!

i'm really looking forward to this feature as it will make some web 
development we need to do much more streamlined. i'm guessing M9 will be out 
some time in the next week, is there any chance that this feature will make 
it? is it going into the daily builds? (i'm not even sure that there are daily 
builds of the VWP but anyway)

thanks alot,
matt

EJB 2.1 D & D consumption is targetted for M10.
Comment 3 matt_tricks 2007-06-12 05:59:14 UTC
Ouch, just noticed the 2.1 bit. Does that mean EJB3 won't be supported? Is it 
targeted for a later release?
Comment 4 _ edwingo 2007-06-12 18:31:36 UTC
As I understand it, the goal is to migrate Creator 2 users to NetBeans 6. This means that EJB 2.1 consumption support in
Creator 2 needs to be in NB6. Not sure about future plans. It either depends on management priorities or if someone
wants to implement it on their own as it is an open source project. By EJB 3 support, could you explain what scenarios
in particular you want supported?
Comment 5 _ edwingo 2007-06-18 16:56:20 UTC
This task tracks migration of Creator 2 EJB 2.1 consumption in NetBeans 6. As for EJB 3 support, I believe NB6 has the
"Call EJB" action in web projects context menu.
Comment 6 _ edwingo 2007-06-27 22:30:03 UTC
Visual Consumption of EJB 2.1 in Visual web apps 90455 is supported in NetBeans 6 as a migration path for Creator users.
Creator ships with a bundled Sun App Server where web apps are test deployed to. This feature allows the web app to
consume Session EJBs hosted on other app servers such as Sun, WebLogic, and WebSphere; however a limitation still
remains, the web app itself needs to be test deployed on a Sun app server for the automatic configuration to work. If
you want to host the web app in another app server, you must manually configure the EJB reference to JNDI binding which
is container specific. When deploying your web app on a production server using the export war feature, this manual
configuration step is part of the Java EE deployment process which is container specific.

Hi guys,

Sorry it was probably me not thinking through how it would work. I was thinking that the Visual Web component would 
need to understand the annotations from an EJB3 entity to define the data mapping but it will be loading the data 
model based on a deployed session bean I guess.

I also wasn't sure how different an EJB3 session bean looked to the container. Judging by your confusion as to my 
question I'm guessing there's a cross-compatibility there. I've never really looked into the low levels of what goes 
on down there, all I know is EJB3 is 1000 times easier to code and if I can derive data models for visual components 
based on my EJB3 beans then it will be happy days indeed.

Cheers,
Matt

matt_tricks: It sounds like you want to use JPA and Entity Beans. I know there are people who have written apps that do
this and netbeans supports JPA and EJB3 OR mapping. I suggest you post to nbusers or do searches on the subject. I think
there is a tutorial that shows how netbeans can generate Entity Beans from a DB. HTH.
