java/php bridge 问题

Question

import javax.script.*;

public class Test{
    public static void main(String[] args){
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByExtension("php");
        try {
           String a = (String)engine.eval("echo 'aaa';");
           System.out.println(a);
        } catch (ScriptException ex) {
            ex.printStackTrace();
        }
    } 

这里运行报错。
