* {cagrid-globus-download-link}
* (Optional) If you want to deploy services to tomcat, you will need [Tomcat 5.0.28|http://archive.apache.org/dist/tomcat/tomcat-5/v5.0.28/bin/]
** Other versions of tomcat will work, but they aren't officially supported (read:tested) by caGrid.
* (Optional) If you are deploying caGrid core services locally, you may also need [a MySQL database|http://dev.mysql.com/downloads/mysql/5.0.html]. \*NOTE:*MySQL is only required for the security services and GME. You can use 4.x (with transaction enabled; i.e. use InnoDB engine) or 5.x (except with GME).

*The caGrid Installer will install all of these prerequisites except for Java and MySQL.*
