1-How to Develop Container-Managed-Relationships

This article is about how I managed to build CMR Entity Beans using the Developing Container-Managed Relationships example of tinptB ‘s Blog: EJB in 21 Days: http://ejbvn.wordpress.com/
I appreciate her excellent English, which makes a soothing effect while trying to break through difficulties.

TINPTB’s work for the 12th Day misses some deployment descriptor scripts which she indicated with “. . . “ .
There also the name problem related to ‘order’ which is actually a key word and gets mixed. Jndi.properties is also missing in this example. Without any further aloboration, follows my solution below full and completely working with: Jdeveloper 11g(only the client not the deployment), WebLogic10.3, wlfullclient5, apache-ant-1.7.1 and mysql-essential-5.1.30-win32, mysql-connector-java-5.0.8 and Toad for MySQL 4.1 Freeware.
