Hi,

I am trying to render a html page which contains ajax requests to be completed. I am able to generate the page properly including the ajax responses, but an error / exception is spit out at the time of the ajax request. Can someone help me figure out the root cause of this problem?

Thanks in advance.

My code: 

public static void rendercompleteHTMLWithCobra() {
    System.out.println( "start" );
    // cobra.jar, js.jar
    try {
        //String urlString = "http://www.fidelity.ca/cs/Satellite/en/public/home";
        String urlString = "http://www.fidelity.ca/cs/Satellite/en/public/products/mutual_funds/equity_funds/cdn_equity/de";
        URL url = new URL(urlString);
        HttpURLConnection con = (HttpURLConnection)url.openConnection();
        InputStream input = con.getInputStream();
        // Create user agent context
        SimpleUserAgentContext context = new SimpleUserAgentContextExt();
        context.setScriptingEnabled( true );
        context.setExternalCSSEnabled( true );
        DocumentBuilderImpl dbi = new DocumentBuilderImpl(context);
        HTMLDocumentImpl document = (HTMLDocumentImpl)dbi.createDocument( new InputSourceImpl( urlString ) );
        document.addDocumentNotificationListener( new DBListener() );
        HtmlParser parser = new HtmlParser(context, document); 
        parser.parse( input ); 
    }
    catch ( Exception e ) {
        e.printStackTrace();
    }
}

class SimpleUserAgentContextExt extends SimpleUserAgentContext {
    @Override
    public HttpRequest createHttpRequest() {
        System.out.println("Creating http request for agent");
        final HttpRequest httpRequest = new SimpleHttpRequest(this, this.getProxy());
        httpRequest.addReadyStateChangeListener(new ReadyStateChangeListener() {
            public void readyStateChanged() {
                if(httpRequest.getReadyState() == HttpRequest.STATE_COMPLETE) {
                    String resp = httpRequest.getResponseText();
                    System.out.println( "State complete " );
                }
            }
        });
        return httpRequest;
    }   
}
class DBListener implements DocumentNotificationListener {
    public void sizeInvalidated(NodeImpl node) {
        System.out.println( "Size invalidated " + node.getInnerHTML() );
    }

    public void lookInvalidated(NodeImpl node) { System.out.println( "lookInvalidated "  ); }
    public void positionInvalidated(NodeImpl node) { System.out.println( "positionInvalidated " ); }
    public void invalidated(NodeImpl node) { System.out.println( "invalidated " + node.getInnerHTML() ); }
    public void nodeLoaded(NodeImpl node) {}
    public void structureInvalidated(NodeImpl node) { System.out.println( "structureInvalidated " ); }
    public void externalScriptLoading(NodeImpl node) { System.out.println( "externalScriptLoading " ); }
    public void allInvalidated() { System.out.println( "allInvalidated " ); }
}

The exception:
