I am just starting with Zend and am having an issue wherein browsing <http://localhost> renders a blank page. I've set httpd.conf documentroot to /var/www/HTML/public and enabled Zend\_layout in bootstrap.PHP. My index.phtml is locatrd in the suggested directory per the .ZF manual. 

Does IndexComtroller have to specifically call my index.phtml view? What other things should I check?

Thanks Much!

EDIT: I checked httpd.conf and noted mod rewrite is enabled. .htaccess file in /var/www/html/public has ReWrite Engine ON etc. I've not created a VirtualHost entry in httpd.conf. I simply defined DocumentRoot "/var/www/html/public" Is a virtualhost required to run the framework?

EDIT2: I used php -f /var/www/html/public/index.php and received the following

```
PHP Warning: require_once(Zend/Application.php): failed to open stream: No such 
file or directory in /var/www/html/public/index.php on line 18
PHP Fatal Error: require_once(): Failed opening required 'Zend/Application.php' 
(include_path=':.:/usr/share/pear:/usr/share/php') in /var/www/html/public/index.php
