Finding and installing the prerequisites

Download OpenCms:

Of course you need OpenCms itself.

Download it from the OpenCms website or see how to build it from the sources.

To run OpenCms you need:

• A database system that is supported by OpenCms
• Java 1.5.x or higher (support for java V1.4 is disconnected)
• A servlet container (aka. 'servlet engine') that forms the basis for running OpenCms, look at tomcat

The most well-tested open source components for getting started with OpenCms are:

• Mysql, Version 4.0 or higher as database system
• Oracle Java, Version 1.5 or higher
• Jakarta Tomcat, Version 5.0 or higher as servlet container

It is not totally necessary, but a good idea to install a webserver like Apache, for handling all requests that arrive at your website.

Another optional component is Apache Portable Runtime, a set of libraries that increase Tomcat performance.
