Introduction

JS7 Agents can execute JVM Jobs running in an Oracle® GraalVM that are implemented using JavaScript.

• The Oracle® GraalVM includes an OpenJDK and a number of interpreters for scripting languages such as JavaScript, Python etc.
• The JS7 - Job API offers such jobs access to arguments, return values etc.

The following information applies to JVM Jobs, not to Shell Jobs that directly invoke a Java Virtual Machine or an interpreter such as Node.js.

• For direct invocation of Node.js with jobs see JS7 - How to run Node.js JavaScript from Shell Jobs
