Instead of that you can put the <connection-url> separated by delimiters in your main <local-tx-datasource> element inside *-ds.xml. Even <url-delimiter> can be included inside.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've tested it using this configuration:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><datasources><br/>   <local-tx-datasource>   <br/>      <!-- The jndi name of the DataSource, it is prefixed with java:/ --><br/>      <!-- Datasources are not available outside the virtual machine --><br/>      <jndi-name>OracleDS</jndi-name><br/>      <connection-url>jdbc:oracle:thin:@localhost:1521:orcl|jdbc:oracle:thin:@localhost:1521:study</connection-url><br/>      <url-delimiter>|</url-delimiter><br/>      <!-- The driver class --><br/>      <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>      <br/>      <!-- The login and password --><br/>      <user-name>xxx</user-name><br/>      <password>yyy</password>      <br/>      <min-pool-size>5</min-pool-size><br/>      <!-- The maximum connections in a pool/sub-pool --><br/>      <max-pool-size>20</max-pool-size><br/>      <!-- The time before an unused connection is destroyed --><br/>      <idle-timeout-minutes>0</idle-timeout-minutes>      <br/>      <!-- Whether to check all statements are closed when the connection is returned to the pool,<br/>           this is a debugging feature that should be turned off in production --><br/>      <track-statements/>      <br/>      <!-- Benefits from prepared statement caching --><br/>      <prepared-statement-cache-size>32</prepared-statement-cache-size>      <br/>      <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --><br/>      <metadata><br/>         <type-mapping>Oracle9i</type-mapping><br/>      </metadata>      <br/>   </local-tx-datasource> <br/></datasources></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>And it is working.
