| WA1048 EJB Programming with WebSphere Studio Application Developer V4 |
|
This course is an advanced introduction to the Enterprise Java Bean (EJB)
technology. It starts by introducing the concepts and is, therefore, ideal
for someone who has never programmed using EJB. The course rapidly picks
up and ends with advanced concepts that students can use in real life to
complete large scale EJB-based projects. The development and labs will
be based on IBM WebSphere Studio Application Developer (WSAD). |

| Practical work |
|
Students develop session beans using WSAD, including accessing a database
from session beans and EJB Java clients. Then they develop CMP entity beans,
including EJB/RBD mapping and finder methods. Students will also develop
access beans. The purpose is to display the use of development, testing
and deployment tools for the improvement of EJB development productivity. |
