Hi Guru ,

Replace

<property name="connection.datasource">J2E/SAPJ2EDB</property>

with

<property name="connection.datasource">jdbc/SAPJ2EDB</property>

here the datasource name u have to look up with

this way <b>jdbc/SAPJ2EDB</b>

i think this is the problem.

SAPJ2EDB , is the default DataSource name for Max DB .

HI Guru ,

what u have to do here is ,(Main things to note)

1)Create the hibernate.cfg.xml file with ur custom configuration. just keep this within your WEB-INF/classes

of your Web Module project.(Related with this sample application).

2) create ur Message class .(code in example).

3)Create Message.hbm.xml with prefered configuration and put it in the same folder of your class.
