Robert Chesebrough Robert Chesebrough Robert Augustus Chesebrough, (January 9, 1837 – September 8, 1933) was an American chemist. He discovered petroleum jelly which he marketed as Vaseline and he founded the Chesebrough Manufacturing Company. Born in London to American parents, he was raised in New York City. Chesebrough began his career as a chemist clarifying kerosene from the oil of sperm whales.

This led to his discovery of petroleum jelly, which he trade-named as
Apache Jelly 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. Jelly is also used by the ServiceNow platform, which uses Jelly tag-language for scripting, and by the Jenkins continuous integration server, which uses Jelly to allow plugins to extend its UI. Apache Jelly Apache Jelly is a Java and XML based scripting and processing engine for turning XML into executable code.
