EJB properties

Chapter 14 Working with Java

EJB properties

You can open the EJB page in the component property sheet to display the following properties:

Property	Description
Remote home interface	Defines methods and operations used in a remote client view. Extends the javax.ejb.EJBHome interface
Remote interface	Provides the remote client view. Extends the javax.ejb.EJBObject interface
Local home interface	Defines methods and operations used locally in a local client view. Extends the javax.ejb.EJBLocal-Home interface
Local interface	Allows beans to be tightly coupled with their clients and to be directly accessed. Extends the javax.ejb.EJBLocalObject interface
Bean class	Class implementing the bean business methods
Primary key class	Class providing a pointer into the database. It is linked to the Bean class. Only applicable to entity beans

For more information on interface methods and implementation methods, see section Understanding operation synchronization.

Opening the EJB page
You can open the EJB page by right clicking the EJB component symbol in the diagram, and selecting EJB from the contextual menu.

Previewing the component code

You can preview the code of an EJB by clicking the Preview tab in the component property sheet. The Preview page contains tabbed pages that correspond to each interface and class of the EJB. You can see the relation between an EJB and its classes and interfaces from the Preview page without generating any file.

In the class and interface property sheets, the Preview page is a keyboard shortcut to show what will be generated.

In the model or package property sheet, the Preview page describes the EJB deployment descriptor file with the name of the generated EJB and its methods. It allows you to view what will be generated.

You can use the following tools and keyboard shortcuts from the Preview toolbar:

Tool	Description	Keyboard shortcut
	Open Editor Contextual menu	Shift + F11
	Refresh	F5
	Show Generation Options	ctrl + W
	Select Generation Targets	ctrl + F6

Showing generation options

If you click the Show Generation Options tool, the Generation Options dialog box appears. You can change generation options from this dialog box and see the impact on the code.

Select Generation Targets

This tool is available when at least one extended model definition flagged for generation is linked to the model, and when it contains entries in the Generated Files category for the current type of object. When available, it displays the list of targets for the current object. If you add a generation target, the corresponding tab is added to the Preview page. If you deselect a generation target, the corresponding tab disappears from the Preview page.

For more information on setting an extended model definition for generation, see section Generating for an extended model definition, in chapter Extended Model Definitions Reference Guide, in the Advanced User Documentation .

Script bookmarks

In the Preview page, you can add and remove bookmarks at specific points in the code and then navigate forwards or backwards from bookmark to bookmark:

Keyboard shortcut	Description
ctrl + F2	Adds a new bookmark. A blue bookmark box appears. If you repeat this action from the same position, the bookmark is deleted and the blue marker disappears
F2	Jumps to bookmark
shift + F2	Jumps to previous bookmark

Note that bookmarks are not printable and are lost if you use the Refresh, or Show Generation Options tools.
