J2ME help!

Using a database like SQL with j2me is not possible . So we use xml sheets to store different usernames and passwords. you need some jaxp knowladge for that.If you dont know all that stuff better you can store all names and passws in a text file in that jar file itself and retrieve data from that text file using streams concept.which is basic and fundamental one.only problem with this is that u dont have security..

Well in Java Web development, J2EE, we use SQL. And in general whenever it comes to storing data, the first thing that comes to my mind is database, and hence SQL. Cant you use SQL with J2ME
