scheduler servlet

[Zhou Kathy <vkathy1211@yahoo.com>]

I need some hints here.
In the cold fusion, we are able to set up a task
running on schedule, such as running this task
midnight every day. I am asking if there is any way to
build a java servlet to make a jsp page running on
schedule. 
I am using the jrun3.1/Unix and I check the knowledge
base on the Macromedia site. I could not make the
servlet work according to the way they suggest on
article 21708 and 22440. 
The error I got is "no such servlet".
Could anyone give me some suggestions on it?

Thanks for help.

Kathy
