I am new in Linux configure Apache. I got few questions to ask. I am will grateful for the help. Thanks.

1) In the Apache Configuration File, where is actually the base for the web tree?

2) I wanted to create a directory (called java) inside the base of the web tree. How am I going to do that?

3) I wanted to make this directory (called java) to be protected. I only allow the user (named glenn) with the password (glenn) to see the contents of the directory (called java). How am I going to do that? I know I need to create a .htaccess file but I don't how to do it.
