GWT - No CAPTCHA reCAPTCHA
Is it possible to use new No CAPTCHA reCAPTCHA (http://googlewebmastercentral.blogspot.ie/2014/12/are-you-robot-introducing-no-captcha.html) with GWT? For old style I think https://code.google.com/p/gwt-recaptcha/ worked with GWT Just wondering how to use new API with GWT Thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Can we build GWT app that does not have Captcha function but is still able to prevent spam?
I am building Gwt site for mobile devices. The screen size of the mobile devices is very small, so I think if i require users to enter Captcha when they register then it could be quite cumbersome. I heard that we can use some Javascript technique to prevent the Spam without needing to use captcha. GWT is all about Javascript, so I am not sure if GWT has any technology to prevent spam without using Captcha? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT does not have any pre-made spam protection code. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Anything client side can be compromised by spammers, so implement some server side CAPTCHA or equivalent.

Most likely you have to generate a personal key for your domain. If you don't do this the captcha will work on localhost (for testing), but not on your domain. And no - this is almost for sure not a GWT problem, Best, Raphael thanks in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Reload captcha
Hi, I have a SimpleCaptcha (http://simplecaptcha.sourceforge.net/ index.html) in one of my page. On submission of this page, I do a validation of the captcha answer entered by the user. If incorrect I reload the same page with an error message. This time I need a new captcha to be shown to the user. This works as expected in hosted mode, but when I deploy the same on liferay portal, I get the old captcha. Can someone let me know how this can be fixed? Thanks in advance.

Showing Captcha using UiBinder
I have a registration page for new users using SimpleCaptcha. I got it to work without UiBinder but can't get it to work with. Does anyone have any ideas to what I'm doing wrong? The following works (without UiBinder): private static String html = divtable ... trtd id= \captchaImageContainer\/td/tr ... /table/div; HTMLPanel panel = new HTMLPanel(html); ... private Image captchaImage = new Image(/SimpleCaptcha.jpg); ... panel.add(captchaImage, captchaImageContainer); But when I try to convert it to UiBinder: In my XML file: g:Image ui:field=captchaImage / In the view: @UiField Image captchaImage; ... widget = uiBinder.createAndBindUi(this); captchaImage = new Image(/SimpleCaptcha.jpg); Am I missing something here? Any ideas appreciated. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-toolkit@googlegroups.com.

Re: Showing Captcha using UiBinder
Create your image *before* the createAndBindUi and use @UiField(provided=true) on your field, to tell UiBinder that it should use the field's value rather than construct the widget and inject it into the field. ...or you can let UiBinder create the image and simply do a setUrl() afterwards. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT and re-Captcha
This is sort of a refinement to:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/99c259aad06406c6/f7fb27b8fa47760d?lnk=gstq=GWT+recaptcha#f7fb27b8fa47760d
The idea here is I wanted a captcha control that I can insert in my
GWT Dialogs. I have pasted the composite below to share. A little bit
of a hack because of the creation of Label dummyLable = new Label();
and manipulating the Element to set the ID attribute. Prerequisite to
using this control is to load the reCaptcha script:
script type=text/javascript src=http://api.recaptcha.net/js/
recaptcha_ajax.js/script
public class CaptchaComposite extends Composite {
private Grid grid = new Grid(1, 1);
private static final String DIV_NAME = recaptcha_div;
public CaptchaComposite() {
this.initWidget(grid);
Label dummyLable = new Label();
grid.setWidget(0, 0, dummyLable);
Element divElement = dummyLable.getElement();
divElement.setAttribute(id, DIV_NAME);
}
private void createChallenge() {
createNewChallengeJSNI();
}
public String getChallengeField() {
String value = getChallengeJSNI();
PMLogger.debug(challenge= + value);
return value;
}
public String getResponse() {
String value = getResponseJSNI();
PMLogger.debug(response= + value);
return value;
}
private native String getResponseJSNI()
/*-{
return $wnd.Recaptcha.get_response();
}-*/;
private native String getChallengeJSNI()
/*-{
return $wnd.Recaptcha.get_challenge();
}-*/;
private native void createNewChallengeJSNI()
/*-{
$wnd.Recaptcha.create(your public key here,
recaptcha_div, {
theme: red,
callback: $wnd.Recaptcha.focus_response_field
});
}-*/;
private native void reloadChallengeJSNI()
/*-{
$wnd.Recaptcha.reload();
}-*/;
private native void destroyJSNI()
/*-{
$wnd.Recaptcha.destroy();
}-*/;
public void createNewChallenge() {
reloadChallengeJSNI();
}
public void destroyCaptcha() {
destroyJSNI();
}
@Override
protected void onAttach() {
super.onAttach();
createChallenge();
}
}

Recommendations for Captcha?
Hi guys, I'd like to integrate a captcha into my registration page, so I thought I'd ping the community to see what other people are using and what their recommendations are for a Java/Servlet implementation? I've tried JCaptcha. It's a good project and straightforward to use, but I've found the distortion factor to be too great (others have also voiced concerns about this). My feeling is that this will prove to be a limiting factor w.r.t. user experience (e.g. you have to refresh a handful of times before someone like my mom gets lucky and can correctly read the characters...). Also, I'm looking for open source or free project recommendations.

servlet mapping, captcha and image...
I have a kaptcha which i have to define in my web.xml as servlet-mapping servlet-nameKaptcha/servlet-name url-pattern/kaptcha.jpg/url-pattern /servlet-mapping In hosted mode where the module is inherited ( no explicit web.xml definition ), code like Image img = new Image(/kaptcha.jpg); works fine. But when i deploy my app, the code will not work, but code below works... Image img = new Image(kaptcha.jpg); I dont want to change code just for the app server build alone. Can anybody help why this would happen ? Something to do with how the url pattern is formed in hosted mode...any ideas ?

Re: Captcha
Micky, I came across this one on SourceForge.net: http://sourceforge.net/search/?type_of_search=softwords=skewpassimage I wasn't able to get the jar file to work in my environment so I included the source in with mine and made the modifications to it needed to get it to run properly in my environment. So far I like the results. David --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

I bet there are no 'robots', that can automatically execute javascript, that GWT produce. As it require normal browser. As for me, GWT is already something like capcha, that not allows fully automatic bots to do actions.
