CDP J2EE UI Specification: EJB Module Editor (Session EJB)


Author: Jiri Kopsa

$Revision: 1.1 $
$Date: 2005/04/25 13:35:43 $
Changes: available in CVS


Overview

This is specification of a Session EJB section of the EJB Module Editor. It is presented as a mockup interlaced with specification sections (enclosed in a yellow frame).

There are still some unresolved questions.

Specification
SessionEJB1

Overview     

Name (ejb-name): 

Session Type:        Stateless              Statefull

Transaction Type:  Bean                     Container

Validation


1. All fields are required, name has to be a valid identifier.

Notes


1. Change of the ejb name should invoke a refactoring feature, that changes the ejb-name in all references within a module (or enterprise application).


EJB Implementation and Interfaces
Bean class: 

Local Interface
Component: 

Home:

Remote interface
Component:
Home:


 

Notes


1. Change classes button invokes a modal dialog, where exposure (interfaces - local/remote/both), packages and class names can be specified (basicly the same design as in the view). When the dialog is confirmed, changes are reflected to java files and the deployment descriptor is saved - it probably invokes refactoring action.

Validation


The validation is done in the "Change Classes" dialog.
The class names (including packages) must be a valid class name.



Bean Environment

EJB References

Reference Name
 Linked Enterprise Bean
 Interface
 Description
Entity1EB
 Module1.jar#Entity1
 local
FooSessionSB
 MyModule#FooSessionSB
 remote

Components

1. Add button, opens the "Add EJB Reference dialog".
2. Remove button, removes selected ejb reference.
3. Linked Enterprise Bean should contain project name and display-name if possible (i.e. jar file name and ejb-name should be translated).

Behaviour

All the columns except Description are uneditable.

Notes


1. Type and inteface classes (values needed for ejb-jar.xml) should be determined from the referenced EJB.

Modules tree: All opened EJB Module projects and their Enterprise Beans will be shown (only Session Beans and Entity Beans, no childs of EJBs, no other nodes). The tree is using display-names if they are available.
Reference name editable text field - defaults to an ejb name of selected Enterprise Bean.
Behaviour: Only available interfaces of the selected bean should be enabled!
Validation: Reference name is required and an enterprise bean has to be selected.
