Importing beans Importing beans You can import an enterprise bean into an EJB module using the EJB designer. You ll find this useful if you want to import a bean from one EJB module to another or if you ve obtained a bean that has no accompanying deployment descriptors. The source code of the bean you are importing must be in the project s source or class path. To import an enterprise bean, 1 Open the EJB module you want to import the bean into in the EJB designer. 2 Right-click the EJB designer pane and choose Import EJB or click the Import EJB button on the toolbar. The Import EJB dialog box appears: 3 Type the name you want for the bean in the Bean Name field. 4 Select the type of bean you are importing from the Bean Type drop-down list. Your choices are CMP 2.0, CMP 1.1, BMP, Session, or Message-Driven. 5 Specify the bean class name and location in the Bean Class field. You can use the ellipsis ( ) button to locate the bean and the package information will be filled in automatically. 6 Use the interface class fields to specify the interfaces you want to import and their location. You can use the ellipsis ( ) button to locate the interfaces and the package information is filled in for you automatically. 7 If you want to import a primary key class for an entity bean, specify the primary key class and its location in the Primary Key Class field. 8 Click OK. The new bean is imported into the EJB module. Its bean representation appears in the EJB designer along with its inspector, ready for you to edit bean properties. Organizing beans with views The EJB designer allows you to group sets of enterprise beans on views, which help you organize and develop complex EJB projects. Each view acts much like a worksheet in a spreadsheet or a page in a multi-page dialog box. While your EJB module can contain many enterprise beans, only the ones on the current view are visible at any one time in the EJB designer. Therefore, using views removes clutter on the screen and allows you to focus on the beans you are interested in at any one moment. 30 Developing Applications with Enterprise JavaBeans
