I have created a datasource in Jboss Portal 2.6.1. My test server is windows 2003 and jdk 1.5
<datasources>
 <local-tx-datasource>
 <jndi-name>jdbc/JbossDS</jndi-name> <connection-url>jdbc:mysql://localhost:3306/jbossportaldb</connection-url>
 <driver-class>com.mysql.jdbc.Driver</driver-class>
 <user-name>jbossportal</user-name>
 <password>jbossportal</password>
 </local-tx-datasource>
</datasources>
I refer to this datasource in Hibernate.cfg.xml using this property: 
<property name="connection.datasource">java:/jdbc/JbossDS</property>
But when I run my app it is giving this exception: 
javax.naming.NameNotFoundException: jdbc not bound

Also I want to use PortalDS in hibernate.cfg.xml how can I do that? what will be the value of connection.datasource property?
