Hi Rajesh,

Development of EJB in NWDS CE 7.1(as it has two options EJB3.0 and supports EJB2.0 not EJB2.1) is very different from NWDI 7.0(EJB2.0 and EJB2.1)

First decide where you want to create EJB2.0 or EJB 3.0. as Entity beans are not available in EJB3.0.

p.s. You have to use JPA & JTA.

When you will create a EJB project automaticall you'll switch to J2ee perspective.

there manually create beans as

create new -> j2ee -> ejb3.0 or ejb 2.0--> session bean.

1. In the main bean file and directly create a new method there.(not like in NWDI7.0 add new EJB in EJB-Jar.xml)

2. In Outline view right click on each method and say add to remote & local interfaces as you wish.

P.S. please be sure about version of EJB as for EJB3.0 EAR jee5 is needed and for EJB2.0 EAR 1.4 is needed

Use as follows

1) File->New->Project

2) Expand EJB->EJB Project

3) Click Next

4) Project Facets Page -> Select the Version of EJb you want to create either 3.0 or 2.1

5)Next and Click Finish

Your Project will be created

6) Switch to the Java EE Perspective and

7) Select the project created

😎 Right and select New-> Enterprise bean

8)Select the ejb type you want to create.(Session Statefull/stateless, Message...)

complete this wizard.
