aha , sorry for my misunderstanding.
so you mean you want the class name for oracle database and you want to define a datasource in oracle application server ?
i assume that you want to know
jdbc driver class name and its connection url.
here it is :
user and password are your user name and pass and SID is simply your database name.
you should add oracle\product\10.2.0\OraDB\jdbc\lib\
ojdbc14.jar to your classpath to allows the application server to find the class .
