hi everybody

i'm using tomcat 5.0.28 and hibernate. as i have studied and the article
" Using JNDI-bound SessionFactory with Tomcat 4.1+" states that tomcat provides readonly jndi implementation and to use JNDI-bound SessionFactory with Tomcat, we should write custom resource factory class for SessionFactory and setup it Tomcat's configuration i have done the same

i have followed the article provided in: http://www.hibernate.org/416.html

i have placed the following code inside the <GlobalNamingResource> tag wihtin the server.xml



<Resource name="hibernate/SessionFactory" auth="Container"
type="org.hibernate.SessionFactory"/>
<ResourceParams name="hibernate/SessionFactory">
<parameter>
<name>factory</name>
<value>myutil.hibernate.HibernateSessionFactoryTomcatFactory</value>
</parameter>
<parameter>
<name>configuration</name>
<value>hibernate-sample.cfg.xml</value>
</parameter>
</ResourceParams>

now when i start my tomcat i get the following exception:::

i've been searching in the web but not able to get the answer so somebody please help me with this.
thankyou
