I don’t see the version that I need on your download page. What should I do?

Can you define deployment/production environments?

What is Quercus? Is it included as part of Resin?
Quercus is a pioneering open source Java/PHP architecture for web applications and services that is included as part of Resin for no additional fee.
Quercus is an open source 100% Java implementation of the PHP 5 language built into Resin application server - there is no additional download/install. Developers using Resin can launch PHP projects without having to install the standard PHP interpreter as Quercus takes on the role of the PHP engine. With Quercus, PHP applications automatically and immediately take advantage of Resin’s advanced features including connection pooling, distributed sessions, load balancing, and proxy caching.
Quercus implements PHP 5 and a growing list of PHP extensions including APC, iconv, GD, gettext, JSON, MySQL, Oracle, PDF and Postgres. Many popular PHP applications will run as well as, if not better, than the standard PHP interpreter straight out of the box. The growing list of PHP software certified running on Quercus includes DokuWiki, Drupal, Gallery2, Joomla, Mambo, Mantis, MediaWiki, Phorum, phpBB, phpMyAdmin, PHP-Nuke, Wordpress, and XOOPS.
Quercus presents a new mixed Java/PHP approach to web applications and services where Java and PHP is tightly integrated with each other. PHP applications can choose to use Java libraries and technologies like JMS, EJB, SOA frameworks, Hibernate, and Spring. This revolutionary capability is made possible because 1) PHP code is interpreted/compiled into Java and 2) Quercus and its libraries are written entirely in Java. This architecture allows PHP applications and Java libraries to talk directly with one another at the program level. To facilitate this new Java/PHP architecture, Quercus provides an API and interface to expose Java libraries to PHP.
Quercus and Quercus’ PHP libraries are written entirely in Java, thereby taking the advantages of Java applications and infusing them into PHP. PHP applications running on Quercus are simply faster, easier to develop, more capable, more secure, and more scalable than any other PHP solution.
I am interested in having a Caucho developer speak at my JUG (Java user group) or PHP user group. Is this possible?
Please contact Emil Ong, Chief Evangelist, at (858) 456-0300 or emil@caucho.com to discuss the opportunity. We will make our best effort to work with you.
