What Java scripting languages are supported?

Scope

• This article is about Java scripting languages that can be used with Jobs and Monitors that make use of the JobScheduler API in order to control other jobs and job chains, e.g. start, stop.
• For the use of individual scripting languages without use of the JobScheduler API see the following articles:
  • Can I script jobs in the Standard Windows Scripting Languages?
  • Can I script Jobs in the Standard Unix Scripting Languages?

Versions of Java scripting languages and JobScheduler releases

• Use of Colors
  • a green background color signals a recommended scripting language.
