Using Java Servlets

What environment do I need to test your sample program? Can I just test it with JBuilder? ASP page needs IIS Server to run, what kind of service JSP needs? Also, I was wondering if it is possible to create DSN from the page itself as in ASP without having to create through control panel. For example in ASP page I can do

sDSN="DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" + Server.MapPath("db/test.mdb")

set conn=Server.CreateObject("ADODB.Connection")
conn.open sDSN

Appreciate your response.
