Hi ,
What is the JDK version are u uisng? if it is jdk1.1.x then
pointyour class path to classes111.zip(which are the thin driver for
Oracle)
and if your jdk version is jdk2 then place the classes2.zip in the class
path.
Both classes111.zip and classes12.zip are freely downloadable form the
Oracle site
Hope this will help you........

but java.util.Map is not used in my servlet, it looks like the exception
comes from the inside of oracle driver.
why???
