Apache Jelly is a Java and XML based scripting and processing engine for turning XML into executable code.{{Cite web|url=http://commons.apache.org/jelly/|title = Jelly - Jelly : Executable XML}} Jelly is a component of Apache Commons.
Custom XML languages are commonly created to perform some kind of processing action. Jelly is intended to provide a simple XML based processing engine that can be extended to support various custom actions.{{Cite web|url=http://commons.apache.org/jelly/overview.html|title=Jelly - Jelly Overview}}
Usage
CA Project and Portfolio Management, or CA PPM,[https://www.ca.com/us/products/ca-project-portfolio-management.html CA PPM Product Page at ca.com]{{Archive url|url=https://web.archive.org/web/20160220212121/https://www.ca.com/us/products/ca-project-portfolio-management.html|date=2016-02-20}} formerly known as CA Clarity PPM or just Clarity, is a product of Broadcom. CA PPM uses an extended version of the Jelly tag-language as an automation and integration scripting language in its Process Management engine. CA PPM implementation of Jelly is called GEL (Generic Execution Language) and encompasses a new custom tag library that allows easier connection to CA PPM via its XML Open Gateway (XOG). The following example shows how CA PPM implements the classical "Hello World" application.[https://docops.ca.com/ca-ppm/15-2/en/reference/xml-open-gateway-xog-development/xog-gel-scripting CA PPM 15.2 XOG GEL Scripting]{{Dead link|date=October 2023}}
Jelly is also used by the ServiceNow platform, which uses Jelly tag-language for scripting the UI,[https://docs.servicenow.com/bundle/jakarta-servicenow-platform/page/script/general-scripting/reference/r_JellyTags.html Now Platform Scripting - Jelly tags] and by the Jenkins continuous integration server, which uses Jelly to allow plugins to extend its UI.{{Cite web|url=https://cleantestcode.wordpress.com/2013/11/28/how-to-write-a-jenkins-plugin-part-2/|title=How to write a Jenkins Plugin – Part 2|date=2013-11-28|website=Clean Test Code|access-date=2016-12-30}}
