Ejb3 bean not bound

Question

Hi I am new to EJB . Now in our project we are using ejb3 and persistance. So tried
a simple program which I found out from net. But when I am trying to run I am getting
bean not bound. And in JBoss console it is showing error like
ObjectName: jboss.jca:service=DataSourceBinding,name=DefaultDS State: NOTYETINSTALLED
These are all my files.

Hi jadespirit ,
I have the same problem in the same Book example ,my ejb3 project name "BaseHotele" so i follow what u said and this is my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence>
<persistence-unit name="FirstEjb3Tutorial">
*<jta-data-source>java:BaseHoteleDS</jta-data-source>*
<properties>
<property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
But it didn't work i have always HotelTestBean not bound!!
Help PLEASE i think that i had a mistake in the persistence.xml:i have 2 days searching for solutions without a good result!!!!!!!!!!!!!
