Pls help me to get around this problem.

I am new to Hibernate.I am using Hibernate 2.1.
I am using mysql, i create a database "cdviewer".

I created a datasource link using tomcat as below

In the tomcat admin console i done the following things to create a datasource.
In the left panel i click the "Resources ->Data Sources " link and i fill the following values
JNDI Name = jdbc/pullcd
Data Source URL: = jdbc:mysql://localhost/cdviewer
JDBC Driver Class = com.mysql.jdbc.Driver
and username and password also.

After that i click the "Service ->Hosts->Context(/cdviewer)-->Resources-->ResourceLink "
I fill the following values

Name: jdbc/pullcd
Global: jdbc/pullcd
Type :javax.sql.DataSource

After done this , i create a folder "cdviewer" in webapps of tomcat .

I put "hibernate.cfg.xml" file inside /WEB-INF/class folder


<hibernate-configuration>
<session-factory>
<property name="connection.datasource">java:comp/env/jdbc/pullcd</property>
<property name="show_sql">true</property>
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
<mapping resource="CD.hbm.xml"/>
</session-factory>
</hibernate-configuration>


And i written the mapping file also(/WEB-INF/classes/CD>hbm.xml).

My servlet code is
-------------------------------------------------------------------------------------
sessionFactory = new Configuration().addClass(CD.class).buildSessionFactory();

Session session = sessionFactory.openSession();
List cds = session.find("from CD");
-------------------------------------------------------------------------------------
But the following error occurs while accessing the application
