/*
* STEPS TO ACCESS THE ORACLE XE CONNECTION OBJECT USING DATA SOURCE
*
* 1) LOGIN TO ADMIN CONSOLE 2) CREATE DATA SOURCE 3) CREATE DATA
* PROVIDER with a jnDi name (jdbc/MyOracleXEDBJNDI ) 4) PROVIDE THE USER ID & PASSWORD AS ALIAS NAMES
*
* 5)
TEST THE CONNECTION FROM ADMIN CONSOLE 6) WRITE JAVA PROGRAM AND
* USING INITIAL LOOK UP OF WEBSPHERE URL 7) ADD
* com.ibm.ws.webservice.thinclient.jar ( from base v61 runtimes) 8) add
* rsahelpers.jar to external jars( C:program files\
* IBM\SDP\runtimes\base_v61\runtimes\lib) 9) change the scopes of
* datasource and data provider to " ALL SCOPES " 10) restart the server
* as well as scopes are changed 11) add client jar for Oracle xe data
* source ojdbc14.jar 12) get connection object by passing the userid
* and passwordas args to getconenction method.
