Hi, I am having an issue deploying a ha-local-tx-datasource into JBoss 5.0.1 (Java 6 version). local-tx-datasource works fine but when I deploy a ha datasource nothing seems to happen, i.e. nothing is logged to console, and the file appears in the web-console, but no datasource. This is the xml, from my -ds.xml file: | <datasources> | <ha-local-tx-datasource> | <jndi-name>jdbc/DBConnection</jndi-name> | <connection-url>jdbc:oracle:thin:@db1:1521:db1|jdbc:oracle:thin:@db2:1521:db2</connection-url> | <url-delimiter>|</url-delimiter> | | <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> | <user-name>USERNAME</user-name> | <password>PASSWORD</password> | | <!-- The minimum connections in a pool/sub-pool. Pools are lazily constructed on first use --> | <min-pool-size>2</min-pool-size> | | <!-- The maximum connections in a pool/sub-pool --> | <max-pool-size>20</max-pool-size> | | <!-- sql to call on an existing pooled connection when it is obtained from pool - the OracleValidConnectionChecker is prefered --> | <check-valid-connection-sql>select 1 from dual</check-valid-connection-sql> | | <!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool --> | <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name> | | <!-- Checks the Oracle error codes and messages for fatal errors --> | <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> | | <!-- sql to call when connection is created | <new-connection-sql>some arbitrary sql</new-connection-sql> | --> | | </ha-local-tx-datasource> | | </datasources> | If it helps this file works perfectly in JBoss 4.0.3 Thanks for your help View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214626#...
