or 

yarn add node-java-example

1. Configure java path(for jar command).
   if there is no jdk installation, you can also put jar file into your project,
   and add following scripts:
   process.env.Path += ';<your_jar_path>';

Usage

Import module

	* const nodeJavaBridge = require('node-java-bridge');

Load All Jar Classes

	* Limitation: if jar is too large, it will throw array size exceed error.

	nodeJavaBridge.load(jarPath, {sync: true})
	.then((api) => {
		console.log('---- Instance ----');
		console.log(api.Base);
		var b1 = new api.Base();
		console.log(b1.call('my arg'));

		console.log('---- End of Instance ----');

		console.log('---- Static Methods ----');
		console.log(api.Main.Foo());
		console.log('---- End of Static Methods ----');

	}, (err) => {
		console.log('Error');
		console.log(err);
	})
	.catch((err) => {
		console.log('---- Catch ----');
		console.log(err);
	});

Load part of jar

nodeJavaBridge.addClassPath('./Main.jar');
var Main = nodeJavaBridge.loadJarModuleAsync('com/example/api/Main');
console.log(Main);

console.log('---- dumpMethods ----');
console.log(nodeJavaBridge.getClassMethods('com.example.api.instance.Concrete'));
console.log('---- End of dumpMethods ----');
