hello marcelo,
i tried your code sample.
but i have some problems:
if i don't include the servlet.jar in the classpath i (obviously) get
this kind of compile errors:
Line 67, column 7: Class javax.servlet.http.Cookie not found in import.
Line 69, column 7: Class javax.servlet.http.HttpSession not found in
import.
but when i do include the servlet.jar everything compiles ok, but i get a
nasty runtime error:
java.lang.NoSuchMethodError

at java.lang.Thread.run(Thread.java:484)
what should i do to get things running?
i'm using
jdk version 1.3.1_01
jsdk (servlet.jar) version 2.1
sincerily,
arjen stolk
