No resource manager found for jdbc/DB

[manan]

I am trying to make database connection with Oracle. ( Database and JBoss are on different machines) but I am facing problems.

Error displayed is -"No resource manager found for jdbc/DB"

in JBoss.xml,
code related to database look up is there:

<resource-managers>
<resource-manager>
<res-name>DB</res-name>
<res-jndi-name>java:/DB</res-jndi-name>
</resource-manager>
</resource-managers>

in ejb-jar.xml,
code related to database look up is there
<resource-ref>
No Description
<res-ref-name>jdbc/DB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

Error displayed is -"No resource manager found for jdbc/DB"

Do I need to define CONTEXT for jdbc/DB. If yes, where and in which file?
Any pointers?

Here you need to map to the name you created in ejb-jar.xml:

>
> <resource-managers>
> <resource-manager>
> <res-name>DB</res-name>

So the above should be jdbc/DB
