Entity Beans

In this example, two beans share the same interface (Account), one uses bean-managed persistence (explicit persistence), the other uses container-managed persistence (implicit persistence). This is a good example of the two persistence techniques.

Finding the Example Application

The Entity Bean example application is located in the $JONAS_ROOT/examples/src/eb directory. It is composed of the following files:

-rw-r--r-- 1024 Apr 25 2003 Account.idb -rw-r--r-- 2048 Apr 25 2003 Account.java -rw-r--r-- 1024 Apr 25 2003 Account.pqsql -rw-r--r-- 1024 Apr 25 2003 Account.sql -rw-r--r-- 19456 Apr 25 2003 AccountExplBean.java -rw-r--r-- 2048 Apr 25 2003 AccountHome.java -rw-r--r-- 10752 Apr 25 2003 AccountImpl2Bean.java -rw-r--r-- 11264 Apr 25 2003 AccountImplBean.java -rw-r--r-- 1024 Apr 25 2003 AccountMySQL.sql -rw-r--r-- 6144 Apr 25 2003 ClientAccount.java -rw-r--r-- 3072 Apr 25 2003 compile.bat -rw-r--r-- 3072 Apr 25 2003 compile.sh drwxr-xr-x 2048 Apr 25 2003 davidclt -rw-r--r-- 9728 Apr 25 2003 db1.prp -rw-r--r-- 4096 Apr 25 2003 eb.xml -rw-r--r-- 2048 Apr 25 2003 jonas-eb.xml -rw-r--r-- 2560 Apr 25 2003 README
