Macromedia JRun 4

Macromedia JRun 4 is a J2EE application server that was marketed by Macromedia and then Adobe Systems.

Product history
JRun was originally developed in 1997 as a Java servlet engine by Live Software and purchased by Allaire in 1999. A working prototype of JRun 4 was first presented at the 2000 Allaire Developer Conference in Allaire was absorbed into Macromedia through a merger that was completed in March 2001, and then acquired by Adobe Systems when it bought Macromedia in December 2005.

JRun 4 was included as a J2EE application server with Macromedia ColdFusion MX 7 and Adobe ColdFusion 8. 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
Allaire announced at the 2000 Allaire Developer Conference that their product roadmap included a successor to JRun 4, codenamed "Trinity", which would support and  integration services.

However, 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.
