XPages: Running Google’s Chrome V8 Javascript Engine (2)

A while ago I tried to run Google’s V8 Javascript engine on top of XPages, and today I found the reason why my server crashed after the first click: I have tried to load the engine only once (statically), and that killed Domino completly.

Today I moved the code back into the processAction method, and now it works without problems.

package ch.hasselba.xpages.jav8;

import javax.faces.event.AbortProcessingException;
import javax.faces.event.ActionEvent;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class JAV8Test implements javax.faces.event.ActionListener {

    public void processAction(ActionEvent actionEvent)
            throws AbortProcessingException {

        ScriptEngineManager factory = new ScriptEngineManager();
        ScriptEngine engine = factory.getEngineByName("jav8");

        try {
            System.out.println(engine.getClass().getCanonicalName());
            engine.eval("var i=1+1;");
            System.out.println("i = " + engine.get("i"));
        } catch (ScriptException ex) {
            ex.printStackTrace();
        }
    }
}
