I am using JBOSS 4.0.5 on Microsoft Windows XP with a default datasource of MS SQL. I wish to be able to interact with another datasource that is Oracle 10g. However, the only documentation/posts I have found deal with setting up the default datasource to be Oracle. I want to keep my MS SQL default DB and just pull data from the oracle database. What sort of configurations do I have to do? I tried simply adding the oracle-ds.xml file from \jboss\docs\examples\jca to the \jboss\server\default\deploy directory and also adding the oracle jdbc drivers to the CLASSPATH of my startup script (i.e. CLASSPATH=...;%ORACLE_HOME%\db_2\jdbc\lib\classes12.zip) However, when I start up JBOSS and try to interact with the oracle database, it says the jndi is not valid. Am I forgetting something? Do I need to add the ojdbc14.jar file as well or use the classes12.jar file instead? My oracle-ds.xml file looks like this: <datasources> | <local-tx-datasource> | <jndi-name>jdbc/OracleDS</jndi-name> | <connection-url>jdbc:oracle:thin:@test2:1521:orcl</connection-url> | <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> | <user-name>hr</user-name> | <password>hr</password> | <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> | <metadata> | <type-mapping>Oracle8</type-mapping> | </metadata> | </local-tx-datasource> | </datasources> I am using all of the default configurations for the login-config.xml, standardjbosscmp-jdbc.xml, and standardjaws.xml Any help would be greatly appreciated.
