Error in JNDI binding

[Raul]

Hi I am trying to deploy my first web application in JBoss and I am
using MySQL as DB Server. I have configured well my application.xml
file.
The directory structure of my application which I have named as btris
looks like-

META-INF -> application.xml, MANIFEST.MF

btrisApp.jar -> META-INF (jboss-web.xml, ejb-jar.xml), com.classes..

btrisWeb.war -> META-INF (MENIFEST>MF), WEB-INF(web.xml, jstl files),
com.classes..

btrisEJB.jar -> META-INF (jboss-web.xml, ejb-jar.xml), com.classes..

This is my first in developing J2EE aplication.

But I have seen error message in log/server.log file like follows:

Failed to deploy:

I have configured the resource refference part in my WEB.XML file
like:

<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc:mysql</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

and in jboss-web.xml file:

<jboss-web>

<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/mysql</res-ref-name>
<jndi-name>java:/MySqlDS</jndi-name>
</resource-ref>

</jboss-web>

Kindly help how should I proceed
further !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanx in advance.

Hi,
Is that a typo error or the res-ref-name in the web.xml and
jboss-web.xml are different?
