Use

Before you can create an enterprise bean, you need an EJB project to which you can assign it. The EJB project also contains the deployment descriptors that will be included in the EJB JAR file. The EJB project is referenced from an Enterprise project for deployment.

Procedure

Creating EJB Module Projects

       1.      Choose File ® New ® Project.

       2.      On the left pane of the first wizard page, choose J2EE, and on the right pane, select EJB Module Project.

       3.      Choose Next.

       4.      In the Project name field, enter a name for your new EJB Module project.

       5.      Select Use default if you want to create the suggested folder for your project.

If you want to specify a different folder, deselect Use default.

       6.      Choose Finish.

Creating EJB Module DC Projects

...

       1.      Import the relevant development configuration. See Importing Development Configurations.

       2.      Choose File ® New ® Project.

       3.      On the left pane of the first wizard page, choose Development Component, and on the right pane, select Development Component Project.

       4.      Choose Next.

       5.      Select the software component to which the development component is to be assigned.

       6.      Choose Next.

       7.      Specify the project attributes as follows:

Attribute

Description

Vendor

Globally unique vendor ID. It is recommended that you derive this name from the Internet domain of the provider (for example, sap.com).

Name

Unique component name. For more information, refer to Component Names.

Caption

Name with which the DC is referred to in visual tools.

Language

Original language of the DC project.

Local Development Component

Flags the DC as a local DC. You should only activate this option if the DC is not to be checked in to the DTR, but only to be created locally. In this case, no assignment is made to a DTR activity.

However, you can assign the local DC to an activity at a later stage in the project processing. 

Sync Used Activities

Select this if you want to add a standard set of DCs to be used to the DC to be created. The relevant DCs are then synchronized from the DTR and listed individually in the new DC project under Used DCs.

Type

Choose J2EE ® EJB Module.

 

       8.      Choose Next.

       9.      Choose Finish.

Result

In the J2EE Explorer (for ordninary projects) or the J2EE DC Explorer (for DC projects), you can see the project. It has the ejb-jar.xml and ejb-j2ee-engine.xml deployment descriptors, and an ejbModule folder (initially empty). If this is a DC project, it will also have additional components used for working with the NetWeaver Development Infrastructure.

Using the context menu, you can quickly add packages and enterprise beans to the project. Alternatively, use the wizards to get more editing options during the creation procedure.
