I am using Netbeans IDE with JBoss as application server and MySql as Database. I am working on it more than a week and can not able to solve it.
I Placed the mysql-connector-java-5.0.8-bin.jar file in the lib folder and configured the mysql-ds.xml file and placed it in the server\default\deploy
directory. And mysql-ds.xml is as follows

Name of my project is sample and in sample-war file I wrote a JSP to call the EJB methods. And this is as follows

I wrote a remote Stateless session bean and an entity bean.
And my persistence.xml file looks as follows
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="titan" transaction-type="JTA">
<property name="hibernate.hbm2ddl.auto" value="update"/>

When I run the application i got an exception like sample not bound.
When JBoss is started I can see an error in the console. It is
ObjectName: persistence.units:ear=sample2.ear,jar=sample2-ejb.jar,unitName=titan
Reason: javax.naming.NameNotFoundException: jdbc not bound

Hi Jaikiran,
I did that but still it is not working.

With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
