Gwt Request builder - how to return the response string

Question

I need to implement a function that calls a web service and return the response.

I tried

public String getFolderJson(String path) {  
           Stri

Try the same solution offered above except not with an anonymous Callback.

public String getFolderJson(String path) { 

    RequestBuilder builder = new RequestBuilder(...);
    HttpCallback cb=new HttpCallback();

    try {
      builder.sendRequest(null, cb);
    } catch (RequestException e) {
    // exception handling
        logger.severe(cb.err);
    }  

    return cb.result;
}

class HttpCallback implements RequestCallback{

    String result;
    String err;

    HttpCallback(){}

    @Override
    public void onResponseReceived(Request request, Response response) {            
        result=response.getText());     
    }

    @Override
    public void onError(Request request, Throwable exception) {
        err=exception.getMessage();     
    }       
}
