Setting classpath in iPlanet 4.1

[Javed Sardar]

Hi, I am new to iPlanet and using iPlanet 4.1 in my present project.
I have created a virtual directory 'test' and actual path as 'c:/Netscape/Server4/docs/servlet' I have placed a servlet under servlet dir and it runs fine.
If i create a servlet with a package, say com.roman.app and place the directory structur unser servlet directory, the server is not able to find the servlet.
Where am I going wrong. Can somebody pl explain.
Thanks in advance,
Javed.
