Eric Hills [https://community.jboss.org/people/onecoder] created the discussion "JBAS014803: Duplicate resource" To view the discussion, visit: https://community.jboss.org/message/821573#821573 -------------------------------------------------------------- I am converting from JBoss 5 to AS 7.1  we have multiple datasources that use the same pool but with a different user and JNDI name.  I get the duplicate error.  Does anyone know how to deploy.  I have included a segment of my standalone.xml.  If anyone has thoughts it would be very helpful.  I have not found anything in my search other than changing the pool-name.  Also I will need to have 6 total entries similar to this they may all use the same db instance but will have a different JNDI name and different users and passwords. <datasource jndi-name="java:/jdbc/xyz-xxx-reports" pool-name="OracleDS" enabled="true" jta="true" use-java-context="true" use-ccm="true">         <connection-url>      jdbc:oracle:thin:@server:1526:webuat    </connection-url>        <driver>     oracle    </driver>    <security>     <user-name>report_user</user-name>     <password></password>    </security>    <new-connection-sql>select * from dual</new-connection-sql>    <validation>     <check-valid-connection-sql>select * from dual</check-valid-connection-sql>     <background-validation>true</background-validation>     <background-validation-millis>10000</background-validation-millis>     </validation>     <timeout>     <allocation-retry>1</allocation-retry>     </timeout>    </datasource>     <datasource jndi-name="java:/jdbc/abc-analysis" pool-name="OracleDS" enabled="true" jta="true" use-java-context="true" use-ccm="true">                  <connection-url>         jdbc:oracle:thin:@server:1526:webdev        </connection-url>        <driver-class>         oracle        </driver-class>        <security>         <user-name>history_user</user-name>         <password></password>        </security>        <new-connection-sql>select * from dual</new-connection-sql>    <validation>     <check-valid-connection-sql>select * from dual</check-valid-connection-sql>     <background-validation>true</background-validation>     <background-validation-millis>10000</background-validation-millis>     </validation>     <timeout>     <allocation-retry>1</allocation-retry>     </timeout>          </datasource> actual boot log message: 10:05:51,760 ERROR [org.jboss.as.controller.management-operation] Operation ("add") failed - address: ([     ("subsystem" => "datasources"),     ("data-source" => "OracleDS") ]) - failure description: "JBAS014803: Duplicate resource [     (\"subsystem\" => \"datasources\"),     (\"data-source\" => \"OracleDS\") ]" -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/821573#821573] Start a new discussion in Datasource Configuration at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
