Macromedia JRun

The Java Servlet Runner, also known as JRun, is a J2EE application server that was created by Live Software and eventually marketed by Adobe Systems, after a series of acquisitions.

Product history
JRun was originally developed in 1997 as a Java servlet engine by Live Software and subsequently purchased by Allaire, who brought out the first J2EE compliant version. It was acquired by Macromedia prior to its 2001 merger with and takeover of Allaire, and subsequently by Adobe Systems when it bought Macromedia in December 2005. Its latest patch Updater 7 was released by Adobe in 2007. Updater 7 added Sun JDK 1.6 support, Apache 2.2 support, Windows Vista/IIS7 support and Mac OS X 10.4 on Intel support.

Discontinuation
Adobe Systems announced that it would discontinue sales and new feature development of JRun on August 3, 2007. Adobe's ColdFusion development team continued to make updates to its underlying Java engine as required up to ColdFusion 9, but replaced JRun in favor of Apache Tomcat since ColdFusion 10.
