configure tomcat 5.0.28 (on unix) to block directory access

It's a relatively simple task. I recently joined a company which uses _Unix_ for pretty much everything. I come from a windows background so I am having a tough time figuring this out and I am on a deadline (I need to get this done tonight). My question is: how do I _block_ a directory from being served? For example: [**http://localhost/my-webapp/[login to view URL]**][1] is fine. But I want to _**block**_ [**http://localhost/my-webapp/myfiles**][2] (there is no [login to view URL] here, but it shows the content of the whole directory, I want to block it, or password protect it, or display error 403 (access forbidden) message) I know in apache we could configure **_httpd.conf_** but I am not sure how to do this in tomcat (It doesn't look like I am using apache separately). I am just having a tough time even figuring out which file to modify - **[login to view URL]**? or **[login to view URL]** or **[login to view URL]** or what! _Please ask me for more information as you need_. If you want me to look something or do something, then you'll most likely also have to tell me unix command for it. **I know basic commands such as ls, find, grep, mkdir etc. but I am not good with piping multiple commands together. ** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
