[newbie] findDataSource deprecated?

[Johan Wasserman]

Hi,
Im just now converting to rc1.3 and find that findDataSource is
deprecated.  How do you find one of many datasources?
 
FYI:
------
I have a separate class called Database with method runQuery that
returns a resultset to my ActionForm class, I only pass DBName and
QueryString as parameters.  So my previous code where:
In ActionForm:
ResultSet rs = Database.runQuery("logondb", "select username, password
from users where username = '" + uname + "'");
 
Many thanks in advance.
Johan Wasserman.
