Hi as per following Connection pool configuration facing some issue.

Place a copy of mysql-connector-java-[version]-bin.jar in $JBOSS_HOME/server/all/lib. Then, follow the example configuration file named mysql-ds.xml in the $JBOSS_HOME/docs/examples/jca directory that comes with a JBoss binary installation. To activate your DataSource, place an xml file that follows the format of mysql-ds.xml in the deploy subdirectory in either $JBOSS_HOME/server/all, $JBOSS_HOME/server/default, or $JBOSS_HOME/server/[yourconfig] as appropriate.

I am getting following error

resource-ref: jdbc/buinessCaliberDb has no valid JNDI binding. Check the jboss-web/resource-ref.

This is my mysql-ds.xml

<datasources>
  <local-tx-datasource>
    <jndi-name>jdbc/buinessCaliberDb</jndi-name>
    <connection-url>jdbc:mysql:///BUSINESS</connection-url>

</datasources>

and this my web.xml entry

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

and this jboss-web.xml entry

<jboss-web>
  <resource-ref>
     <description>DB Connection</description>
