Creating an Enterprise Application DC 
To deploy your EJB to the server, you need to package it with an Enterprise Application development component.
To create a new Development Component based project of type Enterprise Application, proceed as follows:
Choose the menu path File→ New→Project. A New Project Wizard appears.
Choose Development Infrastructure →Development Component. Choose Next.
Expand the root node with the vendor ID (for example: sap.com ) and select J2EE, and then Enterprise Application. Choose Next.
Expand the node Local Development→MyComponents. Choose Next.
Enter studsapp in the Name field. Choose Next.
Select 5.0 for Java EE version. Choose Next.
7. Assign the reference to the EJB DC project you have created in the last procedure and choose Finish.

The wizard generates a new Enterprise Application DC. The resulting project structure is displayed in the Project Explorer view.
