Well now, with modern machines and JVM (1.4+) you can easily create your application in Java. The only thing if there is some speed problem, you should use native threads intead of green one. > I googled and ran through couple of books and sites to see how to start > and now I'm facing problem: how to structure application? What do you mean by structure ? You can use UML or any method else used for all object oriented programmation... > I created a class named DataConn that reads connection parameters from XML > file and than successfully connects to database.

You just have to put some public methods in that class, and you create a global DataConn (final and public in a class used for your application global datas). Another solution is to used static methods so that there is no object but I don't recommand this solution. > I appreciate any help or recommendation for site or book that will help me > solve this problem! That's kind of you ;) and I hope this mail had helped Olivier
