Java™ EE application clients, Web modules, and individual enterprise
beans in EJB modules can include references to other resources. Reference
types include EJB references, message destination references, resource
references, resource environment references, security role references,
and Web service references. You can use the deployment descriptor
editors to invoke the Add Reference wizard from thedeployment descriptor
editor.
About this task
The Java EE and EJB specifications provide for the means for components
to define "logical" names that refer to other resources. For example,
an EJB reference is a logical name that refers to the home of an enterprise
bean. A Web service reference is a logical name that refers to a Web
service.
You can use the various deployment descriptor editors to
define references. A wizard helps you to define new references, and
you can quickly remove or modify properties of existing references
within the deployment descriptor editor.
Procedure
- In the Enterprise Explorer of the Java EE perspective, select the deployment descriptor
for your project where you want to include a reference. You can define
references for EJB projects, application client projects, and web
projects.
- Right-click the deployment descriptor and select from the pop-up menu.
- Click the References tab to go to
the References page of the deployment descriptor editor.
- Click Add to open the Add Reference
wizard.
Note: For EJB projects, references
are defined on a per bean basis. You must select an existing bean
before you can click Add to define a reference.
