Run a Java library

Use Java classes in JavaScript

1. Include CheerpJ on your page

<script src="https://cjrtnc.leaningtech.com/2.3/loader.js"></script>

2. Initialize CheerpJ and load your Java library

cheerpjInit();
cheerpjRunJar("/app/library.jar");

This will load library.jar from the root of your web server.

3. Call Java from JavaScript

let obj = await cjNew("com.library.MyClass");
await cjCall(obj, "myMethod");
