In all these xml files, wherever you have used "Oracle10g", replace it with "Oracle9i". For example, change your -ds.xml to: | <?xml version="1.0" encoding="UTF-8"?> | <datasources> | <local-tx-datasource> | <jndi-name>OracleDS</jndi-name> | <connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url> | <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> | <user-name>test</user-name> | <password>test</password> | <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> | <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml --> | <metadata> | <type-mapping>Oracle9i</type-mapping> | </metadata> | </local-tx-datasource> | </datasources> | | | The comments that i see in the standardjbosscmp-jdbc.xml, tells this: anonymous wrote : <type-mapping> | Oracle9i | <!-- | | This type-mapping applies both to Oracle 9i and Oracle 10g | | Make sure that you have the latest Oracle 10g version of ojdbc14.jar | --> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154165#...
