user id in javacode vs. user id in J2C Conn ( JAAS)

[Anand Gondhiya]

I am using JDK 1.4 , RAD 7.0 and Webshere Application server 6.1.

I have a dataSource 'CRDWebDataSource' set up in admin console. And with this DataSource , I have used JAAS ( J2C Connection). When I test the DataSource , it works fine.

Now , I have following line of code in Java class

  localConn = dbConnect.getDataSource().getConnection(rd_login, rd_pwd);  

When I run the application ,it ignores the userid/password values getConnection() function and always considers in J2C authentication.

in WSAD 5.1 , I had set up datasource which considers userid/pwd in getConnection().

Please advise.
thanks
