The dialog is shown (by the browser automatically), if the server answers with the HTTP response code for "unauthorized" and the HTTP response header informing about the available authentication types. I'm writing this mail from my mobile phone, so you need to check for the specific values for yourself.

Basic Auth with GWT
Hello! I have a running GWT-App, with a DialogBox as login box, sending login data via RPC to the server and performing the login process. Now it is requested, that the standard basic-auth of http is used. I found one tutorial how to upgrade the web.xml, but that didn't work with GWT 2.0 anymore... What I want is the browser standard basic-auth dialog popping up, entering credentials (maybe saving them if wished), then sending the data to the server, processing the login, and if successful to load the module, otherwise ask again... I found how to send a http request including basic-auth information, but that doesn't take care of integrating the standard browser dialog window. I also have a similar standard java servlet app, that performs all of these tasks as part of the servlet process, by performing the appropriate doGet() method and sending the respective response back... Does anyone know how to accomplish this? Maybe similar to the standard servlet app? (is there a way to not load the module immediately, but first do a GET-Request to a standard servlet and load the module appropriately afterwards?)

Re: How to hot fix a common GWT widget without recompiling the GWT module?

Re: RequestFactory and non-Java (non-GWT) backends
Johan, There is no documentation on the RequestFactory wire protocol. It is subject to change in future releases, so should not be relied upon for creating non-GWT back-ends.

Re: GWT 2.1.RC1 Expenses Sample Failure
Thnaks! This is going to be a very useful pom.xml file.
So long, greeting (sample.).
Just a reminder, the three .txt files from src/main/webapp
folder still needs to be moved to the project's root folder
in order for the sample to work.
By some minor change it even works with newly released
appengine-1.3.8 and Roo-1.1-RC1.
It can even work with the gwt-2.1.0-SNAPSHT form the
maven central. I just wonder how often this snapshot is
going to be updated. Hopefully with every GWT build of
the Hudson CI server.

GWT + App Engine + JSP (Eclipse IDE)
Hello I have plenty of experience with GWT, and my app works on App Engine, only I want to change it so that I can manipulate the page (the base html file) on the very first GET request. Thus, I want to use JSP. For starters my Eclipse (3.5.1) does not natively understand JSP files and I have no idea how to get App Engine to process JSP files, although that might simply be automatic. Can anyone help me get started? I don't need to have any kind of complicated server-side architecture like MVC, I just need to be able to insert some stuff into the JSP file based on some logic in a Java class. I imagine my Java class should go in the /server/ folder inside my /src/ folder. Can I simply change myapp.html to myapp.jsp and put some JSP that calls code from the server side Java class? How do I get Eclipse as well as App Engine to understand JSP files? I see mention of the Eclipse Web Tool Platform, but I don't know if that is a different version of Eclipse than my Eclipse for Java or what. I don't know if the GWT plugin will work for it or what.

Defining an external API for a GWT application
Is there a way to externalize function names within the optimized compiled code so that I can provide an api to those who may wish to consume something I write in GWT?

Re: TabLayoutPanel : How to add a "Add tab" icon in tab bar

Re: GWT 2.1.RC1 Expenses Sample Failure
The Expenses pom.xml has been updated in trunk:
http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/expenses/pom.xml
You should now be able to run "mvn gwt:run" to run in hosted mode or
"mvn package gae:run" to run in production mode. Hit
LoadExpensesDB.html first to load sample data, then Expenses.html to
use the app.
The project will import into Eclipse using m2eclipse or "mvn
eclipse:eclipse". To run from Eclipse with Run as | Web Application,
there's still a GPE fix coming...

GWT 2 UI Binder Flex, Flash widgets

Is there any code examples or library projects that are updated to successfully integrate Flex widgets into the UIBinder. I also want to communicate with the Flex SWF with some parameters.

Re: Developing an AppStore for a GWT / App Engine application?
hello Артём, thank you very much for your input! i kept on thinking about the idea. i had to realise that even if one could compile the plugin code (java) to javascript the _real_ problem still remains: - how can you load this plugin code at runtime? - what are the implications on the development process (i.e. the way plugins are developed/tested) when plugins are loaded dynamically? - what must (not) be part of the plugin javascript source (e.g. to avoid doing gwt initialisation twice (?))? i think there are two ways to build an appstore-ish application using gwt: (1) static plugins: plugins are part of the codebase i.e. they are already "installed". thus they are already part of the platform and users might (in-)activate them using the application itself. for more details about my idea see http://code.google.com/p/honeycrm/wiki/PluginsStaticApproach. (2) dynamic plugins: everyone can potentially create plugin files and publish them somewhere on the net. users will upload them to the (plugin-aware) application. this has to extract the plugin, put the js source into the database and perhaps has to update the configuration. from my point of view (1) is the preferred way of doing it because of the simplicity of a potential implementation. for some sample code see http://honeycrm.googlecode.com/svn/branches/PlatformTest/. (1) simplifies a lot of things - especially the live of the plugin developer. how should plugins be developed and _extracted_ from the development system (for publishing them)? if you want to create external repositories where people can download plugins, they have to be self- contained. how could this be achieved for (2)? however, the most important thing i would like to discuss is: what you think about (1) static plugins http://code.google.com/p/honeycrm/wiki/PluginsStaticApproach kind regards, ingo On 10 Okt., 10:14, Артём wrote: > The first problem I see is that the GWT compiler calls System.exit, > therefore you can't easily call it's "main" function from your > program.

Why can't see progress bar?
Hi all,
I'm trying to put a progress bar but I just can see the values of
progress counting, not the bar widget itself. I already tried with
several progress bars, from different libraries, for example,
gwtwidgets, gwtchismes, gwtext, and now I'm trying with gwtideias from
incubator and no bar shows up:
import com.google.gwt.widgetideas.client.ProgressBar;
public class Exp implements EntryPoint {
private ProgressBar pb2 = new ProgressBar(0.0, 100.0, 0.0);
private HorizontalPanel pbPanel = new
HorizontalPanel();
private Label pbLabel = new Label("Progress Bar: ");
...
public void onModuleLoad() {
...
pbPanel.add(pbLabel);
pbPanel.add(pb2);
form.setWidget(mainPanel);
...
mainPanel.add(pbPanel);
//pb.setText("gwt-file.jar");
pb2.addStyleName("progressbar-solid");
pb2.isVisible();
//pb.setProgress(50); // percent
Timer t = new Timer() {
public void run() {
//int progress = pb2.getProgress()+4;
double progress = pb2.getProgress()+4;
if (progress>100) cancel();
//pb2.setProgress(progress);
pb2.setProgress(progress);
}
};
t.scheduleRepeating(1000);
What Am I doing wrong?

Re: How to use GWT Place?
Hi Guarav, If you haven't already, try out the sample app you can download from http://code.google.com/webtoolkit/doc/trunk/DevGuideMvpActivitiesAndPlaces.html. It's a trivial example, but when you click the link, you can see the GoodbyePlace appear on the URL. Try the back button, reload, bookmark, etc. from there to see why Places are useful. The HelloPlace does not appear on the URL because it's the default place. -- David Chandler Developer Programs Engineer, GWT On Oct 15, 8:51 am, Gaurav Jain wrote: > Please provide some example of how to use gwt place. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Load Test GWT application using JMeter
Hi,
there's several challenges coming with it - but it's solveable: I used
Tamper Data to get the requests going back and forth in a manual
request. I then used the plain TCP connector to build the overall
request. You have to extract at least the session ID to keep session
over requests:
false
SESSIONCOOKIE
Set-Cookie:
(JSESSIONID=[0-9A-F]*).*
$1$
0
You can then insert it into a TCP-Statement like (in the TCP body):
Cookie: ${SESSIONCOOKIE}
You can do the same with values - BUT: you have to adjust the content
length for the right number of bytes...
Hope this helps

Using setFocus(true) on a TextBox in onModuleLoad can cause layout problems
Hi, I have a basic login page with username and password fields, and a submit button. When you click submit a DialogBox displays with an appropriate message and a close button. The problem I have come across is that, if I add setFocus(true) for the username TextBox in onModuleLoad, after closing the DialogBox the objects shift slightly down and to the right. I noticed at the time that the panels, etc are not exactly on center when I first load the page. After they shift they have moved to center. The thing is, that if I do not add setFocus(true) in the onModuleLoad, the panels are all on center and I don't have the problem where things shift. Is this a known bug? Does anyone know a work-around? Please help. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Refresh and back button not working
Spot on. When you press Reload, you're just reloading the HTML host page and reloading the JS. This is a challenge with all JS apps. Fortunately, GWT solves it well with the History object and the various MVP frameworks (including Activities and Places in GWT 2.1) make it even easier. http://code.google.com/webtoolkit/doc/trunk/DevGuideMvpActivitiesAndPlaces.html -- David Chandler Developer Programs Engineer, GWT On Oct 15, 7:53 am, salk31 wrote: > Have you looked at the History class?

CellList/CellBrowser and reload data (possible bug?)
I have been playing around with the new CellBrowser/CellTree Widgets of GWT 2.1RC. However I ran into a weird problem. I am not sure if that's a bug or maybe a mistake on my side. Basically I was followed this tutorial http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellBrowser I created a TreeViewModel and defined the required cells for all levels of the tree/browser respectively (in my case there are 3 levels) I pass a List of my DTOs into the constructor of my CustomTreeViewModel Class. In the constructor I create a ListDataProvider with the List of my DTO objects. At this step everything works just fine. The CellBrowser is populated with the first level and when I click of one entries the next level is shown. As a next step I created a button which should reload the CellBrowser with new data (actually it's the same data). I did this by calling setList(List) on my ListDataAdapter in my CustomTreeViewModel. The CellBrowser is reloaded with the new data and again only the root node/ elements are shown. Here I get a weird problem. If I previously opened an additional level of the CellBrowser (apart from the root level) and I reload the data so that again only the root node/elements are shown and I click on one of the root node elements to expand/display the second level I get following uncaught Exception: 14:00:51.322 [ERROR] [gwasclient] Uncaught exception escaped java.lang.IndexOutOfBoundsException: Index: 1, Size: 1 at java.util.ArrayList.RangeCheck(ArrayList.java:547) at java.util.ArrayList.get(ArrayList.java:322) at com.google.gwt.user.cellview.client.CellBrowser.setChildState(CellBrowser.java: 1027) at com.google.gwt.user.cellview.client.CellBrowser.setChildState(CellBrowser.java: 990) at com.google.gwt.user.cellview.client.CellBrowser.access $7(CellBrowser.java:972) at com.google.gwt.user.cellview.client.CellBrowser $BrowserCellList.doKeyboardSelection(CellBrowser.java:325) at com.google.gwt.user.cellview.client.CellList.onBrowserEvent2(CellList.java: 389) at com.google.gwt.user.cellview.client.CellBrowser $BrowserCellList.onBrowserEvent2(CellBrowser.java:231) at com.google.gwt.user.cellview.client.AbstractHasData.onBrowserEvent(AbstractHasData.java: 454) at com.google.gwt.user.client.DOM.dispatchEventImpl(DOM.java:1308) This happens in the setChildState function of the CellBrowser where nodes get closed and opened. It seems that the when the new Data is set and the CellBrowser get redrawn it forgets to reset the nodes which are shown or hidden and when it tries to reset the collapse/open status of these nodes it throws this exception. So i am not sure if this is a bug or I choose the wrong approach to reload the data of the CellBrowser Maybe somebody has an idea what might be the problem here Uemit -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Refresh and back button not working
Have you looked at the History class? GWT gets around the problem you are talking about by using #foo stuck on the end of the URL (so will work for reload and browser history). http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html Works really nicely.

Re: Refresh and back button not working
First of all,does ur login page has different module associated with it...? it is always a better GWT programming to have login module and other modules for post login functioning. It should be seperated.

Is multiple ClientBundles sub-optimal?
I am wondering if having multiple client bundles is less then an optimal solution. If I have widgets that require a set of images and styles, is it ok to create 1 client bundle for each widget? Or is this suboptimal? I would figure that GWT would generate optimized JavaScript code that didn't really construct the ClientBundle object on each invocation, but rather had them all as static JavaScript variables. The only issue I see is that for older IE browsers GWT would have to generate multiple bundle images, rather than 1 large one. But once downloaded, those would be cached anyways. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Handling session timeout
There are many ways to handle it. You should decide what is important to your users and for your environment, and how you define a session expiration. In one GWT application, I use the Google UserService to get the current user on the server side. I make sure the user is logged in at the start, and I make sure that I handle expired sessions throughout the application when the user makes a new request to the server. It does nothing to detect session expiration on the client side, but the valid session duration is defined in days. Here's a link to a good starting point that uses a timer to detect and process inactivity on the client: http://gwt-ext.com/forum/viewtopic.php?t=1682 The code in the above link uses GWT-Ext widgets, but can be easily adapted to use standard GWT widgets. Keep in mind that there are many different variations of how you define inactivity... Some servers declare your session dead if you have not sent a message in some amount of time -- you could periodically send a "ping" message to insure your session does not go stale. BUT, that may cause you to exceed your request quotas on the Google servers. Then, consider the user experience. If your application is working correctly, your user may not know when messages are going between client/server. So, you may need to track something else to determine when the session is inactive. Lastly, consider how the users see the session expiration. In one GWT application, I did something similar to what is shown in the GWT-Ext link. Some folks using the app did not like the idea that they had been logged out without seeing where in the application they were. So, I changed my app to tell them they had been logged out (with a dialog box), and upon acknowledging the message they were sent to another page. I do not know your particular design constraints, but I think I have given you the highlights of things to consider.

Re: Handling session timeout
There are many ways to handle it, but you need to consider how to present it to your users and other constraints specific to your environment. In one GWT app, I did nothing to detect client-side inactivity. I used the Google UserService to detect session expiration on the server side whenever there was a message from the client (and I wrote the code to handle those case). The Google UserService lets you see the policy on how long the sessions stay active, but it is often measured in days. So, it did not seem worthwhile to write code to handle the session expiration. Here's a link to a client-side that attempts to detect session expiration: http://gwt-ext.com/forum/viewtopic.php?t=1682 The code uses GWT-Ext widgets, but can be easily adapted to use standard GWT widgets. Some servers consider a client's session inactive if they have not received a message from the client in some period of time (as shown in the example). The example code can be adapted to periodically send a "ping" message to the server instead of just detecting messaging inactivity. You probably do NOT want clients sending "pings" to you application if it is deployed on Google's servers, since the pings will probably count against you request quota. Another thing to consider is that if your application is working correctly, the user may not even be aware when messages are exchanged between client/server. For this reason, you may want to introduce some other means of tracking inactivity. Lastly, you need to determine how you want session expiration presented to your user. My users did not care for the way the GWT-Ext example informed the user (particularly if they missed the refresh prompt). My solution was to keep the user at the same screen and present a dialog box informing them when their session timed out. Upon acknowledging the message, they were sent to another place. I tried to hit the highlights of things for you to consider regarding session expiration, but I think you need to tailor your solution for your environment.

fpLoginPanel.addSubmitHandler(new FormPanel.SubmitHandler() {
public void onSubmit(SubmitEvent event) {
// This event is fired just before the form is

CellTable sorting: roadmap?
In the bikeshed example, the CellTable support column sorting, by use of some custom classes called SortableColumn and SortableHeader. Is CellTable sorting support on the roadmap for gwt-user?

Re: problem with asynchronism
One solution that i can suggest for this is keep that button in disable state until user fill up the form fields. and once all compulsory fields got filled properly make that button enable and will have seperate click handlers in that case. -- Aditya On Fri, Oct 15, 2010 at 3:32 PM, pepgrifell wrote: > hi, > > I have a window with some form fields and 2 buttons, "add" and > "cancel".

Inserting images in web page
Suppose I am serving a web page to a gwt client app. The web page html, at various places, has unique string segments which the client app will recognize. The client app should replace the strings with images on the rendered page, just as if the html had tags. Except the images already reside in the client app as Image instances and I don't want to fetch the images from the server. I expect I will need to use JSNI and document.write, or something like that. I am not experienced with Javascript, so I have some learning to do. Has anyone done something like this: a client app inserting its own images into a page?

problem with asynchronism
hi, I have a window with some form fields and 2 buttons, "add" and "cancel". One of the fields has a listener associated. The listener does a RPC call to the server to do a validation and it can update the value. The listener is fired when the field loses the focus. The button "add" sends the data into the form fields to the server side with another RPC call. The problem that I have is: If I change the value of the field, and, without losing the focus, I click in the "add" button, then two RPC calls are done, the one inside the listener and the one associated to the button. I would like that the action associated with the button would be called after the listener action (RPC call) has finished. Is there any way of doing this ?

RequestFactory and non-Java (non-GWT) backends
I have yet to find any documentation on the on-wire protocol that RequestFactory uses. Are there any, or does it have to be reverse-engineered? Also, does GWT _require_ the "service methods" actually be available in the entity class? RequestFactory being based on JSON makes it a better fit for non-Java server-side code. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

getThreadLocalRequest().getSession().getId() confusion
Hi all,
I have an application that does some simple login and session
management. I'm not using any particular frameworks. Here are the
basics of what I'm doing:
1) The user logs in via the front end
2) The credentials are authenticated on the server side using GWT-RPC
3a) The server side returns a dumbed down User POJO with the session
ID set to the client
3b) The server side keeps a fully populated User POJO (including the
session ID) using
getThreadLocalRequest().getSession().setAttribute("user", userFromDB);
4) In each GWT-RPC, the client side sends the User POJO it has in the
parameters (for any RPCs that require some authentication/access
control)
5) The server side gets the session ID in the RPC param User POJO and
compares it with the session ID stored in the User POJO from
getThreadLocalRequest().getSession().getAttribute("user")
If this checks out, the RPC is executed. (please also point out of
this way of authenticating is not ideal/secure)
This has worked for me fine, however I've found that when I'm testing
and have multiple instances of the program open (one running on port
and one 8889) some funny things start to happen:
* Instance on starts, and user logs in:
[18:06:46,026] DEBUG SessionManager:66 - User bob logged in with SID:
15vqhpc1r06yi
* Instance on 8889 starts, and user logs in:
[18:07:04,667] DEBUG SessionManager:66 - User bob logged in with SID:
sd560k3liwvl
Instance 's RPC fails:
[18:07:06,230] ERROR SessionManager:110 - getSession has no user
object:
[18:07:06,230] ERROR SessionManager:111 - client sent: bob, sid:
15vqhpc1r06yi
[18:07:06,230] ERROR SessionManager:112 - server session sid:
1pwzxs8dyzfbn
Instance 8889's RPC also fails:
[18:07:09,901] ERROR SessionManager:110 - getSession has no user
object:
[18:07:09,901] ERROR SessionManager:111 - client sent: bob, sid:
sd560k3liwvl
[18:07:09,901] ERROR SessionManager:112 - server session sid:
nkiyx2iip6l6
This does NOT happen if the two instances are running on different
servers, or I have two browsers both pointing to the same instance.
I'm testing using the latest version of Chrome.
Is there some gap in my understanding? It seems as though getSession
isn't returning the session I expected when I have two instances
running on the same server?
public static User loginUser(User user, HttpServletRequest request) {
user.setSessionId(request.getSession().getId());
user.setPassword(null);
request.getSession().setMaxInactiveInterval(-1);
request.getSession().setAttribute("user", user);
log.debug("User "+user.getUsername()+" logged in with SID:
"+user.getSessionId());
return user;
}
public static void checkUser(User user, HttpServletRequest request)
throws AuthenticationException {
String payloadSID = user.getSessionId();
User serverUser = (User)request.getSession().getAttribute("user");
if (serverUser == null) {
log.error("getSession has no user object: ");
log.error("\tclient sent: "+user.getUsername()+", sid:
"+user.getSessionId());
log.error("\tserver session sid:
"+request.getSession().getId());
throw new AuthenticationException();
}
String serverUserSID = serverUser.getSessionId();
if (!serverUserSID.equals(payloadSID)) {
log.error("Payload/Server SID mismatch for

log.error("Payload SID: "+user.getSessionId());
log.error("Request SID: "+serverUserSID);
