Petroleum jelly plastics and minimize ventilation issues, isopropyl (rubbing) alcohol can be used to remove petroleum jelly from most surfaces. Isopropyl alcohol is inert to most household surfaces, including almost every plastic, and removes petroleum jelly efficiently. While alcohol causes fewer ventilation problems than petroleum solvents, ventilation is still recommended, especially if large surface areas are involved. Petroleum jelly is also soluble in lower-molecular-weight oils. Using an oil to dissolve the petroleum jelly first can render it more soluble to solvents and soaps that would not dissolve pure petroleum jelly. Vegetable oils such as canola and olive oil are commonly used to
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.
