where to put java classes

[Danish Shaukat]

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?

Try using package.

[Danish Shaukat]

Hi !
It works with packages
All classes in .../WEB-INF/classes are automatically added in class path of web application.
Thanks Nitin.

[Majid Khan]

Can you explain in detail.
I tried with packaging the class files ....
still I face the same problem.
Also what do you mean by the last line
All classes in ....
thanks
Majid

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.

Danish
