This example shows how to get the script engine by using the mimetype. This is the first step when you are using the Java script engines for executing the scripts. Before your run the scripts, you must get the javax.script.ScriptEngine instance from javax.script.ScriptEngineManager. The engines are registered using the Names ,Extensions and Mimetype. This example snipped retrieving the script engine by using the mimetype by calling the method getEngineByMimeType().

Lets look at the example.

GetScriptEngineExample.java

package javabeat.net.script;

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

/**

public class GetScriptEngineExample {
	public static void main(String[] args) throws ScriptException{

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

		//Get script engine using name
		ScriptEngine engine = engineManager.getEngineByMimeType("application/javascript");

		//Evaluate simple printing message
		engine.eval("println('ScriptEngine Loaded using MimeTypes!!')");
		engine.eval("print('Welcome To JavaBeat!!!')");

	}
}
