Migrating application from tomcat to jboss

Question

My application is working on tomcat but when try to deploy the same application war file it gives the following error
no valid JNDI binding. Check the jboss-web/resource-ref.
My web.xml is like this(only giving few lines here)
<resource-ref>
Inventory Source
<res-ref-name>jdbc/InventorySource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Jboss-web.xml
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
<!-- Uncomment the security-domain to enable security. You will
need to edit the htmladaptor login configuration to setup the
login modules used to authentication users.
<security-domain>java:/jaas/jmx-console</Dsecurity-domain>
-->
<reference-ref>
<res-ref-name>jdbc/InventorySource</res-ref-name>
<jndi-name>java:jdbc/InventorySource</jndi-name>
</reference-ref>
</jboss-web>
postgres-ds.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- Example of the pointbase 4.8 datasource configuration -->
<!-- $Id: pointbase-ds.xml 23720 2004-09-15 14:37:40Z loubyansky $ -->
<local-tx-datasource>
<jndi-name>jdbc/InventorySource</jndi-name>

In web.xml making the following entry:
<web-app>
<description>MySQL Test App</description>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
Next, add a file jboss-web.xml under WEB-INF/ folder of the web-application. This file should contain entry as:
<jboss-web>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:/jdbc/test</jndi-name>
<res-auth>Container</res-auth>
</resource-ref>
</jboss-web>
Next, in JBOSS_HOME/server/default/deploy folder make a xx-ds.xml file or else, a similiar file can be found in that same folder with the name hsqldb-ds.xml. Make following entries in that xml file:
<datasources>
<local-tx-datasource>
<jndi-name>/jdbc/test</jndi-name>
<type-mapping>MySQL</type-mapping>
<connection-url>jdbc:mysql://localhost:3306/shopping_cart</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>root123</password>
<min-pool-size>1</min-pool-size>
<max-pool-size>5</max-pool-size>
</local-tx-datasource>
This should bind the jndi name.
In our client application, we need to look up as:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/jdbc/test");
Connection conn = ds.getConnection();
This works perfectly.
