Hi all ! I am using tomcat 4.1. I am importing my java class in jsp but i get an internal server error. I'm putting my classes in .../web-inf/classes directory. This approach does work with tomcat 3.2 and i am able to run my jsp. I also tried putting my class in ..\tomcat4.1\server\lib, but still things are not working. I need a some help with this. Regards Danish
The WEB-INF/classes directory should also work in Tomcat 4.x
What is the error you are getting?

Hi Majid, Got your email. You also need to have a web.xml file to make your servlets work on tomcat 4.1. Just search this forum and you will find a way how to write it. Apart from ths every thing is straight forward as explained in previous posts.
