Creating an EJB Project
This section introduces the steps for creating an example EJB Project named "firstejb".
- From the Eclipse menubar select File > New > Project... to open the New Project Wizard.
- In New Project Wizard expand the J2EE folder and select EJB Project (see Figure 2)
- Select Next >.
Figure 2. Opening EJB Project wizard
- Enter firstejb into the Project Name field
- Select J2EE 1.3 option for Specification Level.
The remaining fields are prepopulated from the MyEclipse EJB Project Template. This template is defined under the MyEclipse J2EE Project preferences. Table-1 describes each of the fields for the New J2EE EJB Project wizard shown in Figure 3.

- Select Finish
Completing the wizard creates and configures the firstejb EJB Project. Figure 5 depicts the structure of the new project from the MyEclipse perspective. To open the MyEclipse perspective, from the MyEclipse menubar select Window > Open Perspective > Other and select the MyEclipse perspective,Image:Logo.gi. The Java Package Explorer will be automatically opened as part of the perspective. However, if you close it for some reason, you can manually reopen it by selecting Window > Show View > Java > Package Explorer.
Figure 4 depicts the new EJB project structure. Newly created EJB projects will not include a default ejb-jar.xml file. There are 2 reasons for this: 1) the deployment descriptor will be created later using XDoclet technology and 2) a valid ejb-jar.xml file requires at least 1 EJB definition. At this point in the process, no EJB's exist and a corresponding ejb-jar.xml file would appear in your project with an error marker as a result. The alternative is a simple warning message in the Problems view that identifies that the required ejb-jar.xml deployment descriptor does not yet exist in your project. This file will be created later in this tutorial.
