How To Import Java Package Inside JavaScript using ScriptEngine

April 22, 2014 //  by Krishna Srinivasan//  Leave a Comment

This example show how to import Java package inside JavaScript. We can import the Java package and use the classes inside the scripts. In this example, I have imported the java.util package and use java.util.Date class to print today’s date. Lets look at the example.

JavaScriptEngineImportPackageExample.java

package javabeat.net.script;

import java.io.FileNotFoundException;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

/**
 * Java ScriptEngine Import Package Example

 * @author Krishna

 */
public class JavaScriptEngineImportPackageExample {
	public static void main(String[] args) throws ScriptException,
			FileNotFoundException, NoSuchMethodException {

		// Create ScriptEngineManager
		ScriptEngineManager engineManager = new ScriptEngineManager();

		// Create ScriptEngine
		ScriptEngine engine = engineManager.getEngineByName("ECMAScript");

		//Import package statement in string buffer
		StringBuffer buffer = new StringBuffer();
		buffer.append("importPackage(java.util);");
		buffer.append("");
		buffer.append("var todayDate = new Date();");
		buffer.append("println('Today Date Is ' + todayDate);");

		//Execute the script
		engine.eval(buffer.toString());

	}
}

Output…
