Re: viewport resize listener
Basically you have to listen to browser "change size" events (not sure how reliable this is in all supported browsers) and forward new size to your widgets. Ext GWT (and probably GWT Ext) for example, already has ViewPort implementation.

Not really. With ajax your URL typically doesn't change.

Re: XML to UI Forms
Thanks for your note, Charlie. Is there something I can draw on the fly. I was looking for some generic tool which can build a UI from the xml which can be provided dynamically. Eg: a drag and drop node can be added automatically from a remote xml. This xml will have definition of properties (UI) for user's input when the node is dragged. Is it available in any tools (not necessarily gwt)? Thanks.

Re: Client did not send nnn bytes as expected
Hi and thanks again for your responses. A few more subtle observations and insights: 1. It's probably not the server. There are several reasons that lead us to believe that the server is not the cause of this issue: (a) We switched hosting providers. (b) These providers reside in completely different geographical locations - countries. (c) We have always been using JBoss on CentOS, but this issue occurs both when we work with Apache as a front end using mod_jk to tomcat, as well as when eliminating this tier and having clients go directly to tomcat - using it as an HTTP server. (d) tcpdump sniffer explicitly shows that the server receives ALWAYS EXACTLY 80% of the request payload. Unless this is something even lower level in that machine (the VPS software used - virtuozzo, the network card/driver, etc.), these observations pretty much provides an alibi for the server... I think we'd better focus on other places. 2. There are indications that this is not inside the browser as well: (a) It happens in several GWT versions. (b) It happens "to" all browsers, which provides a strong clue, since this code is completely different from browser to browser - GWT uses MsXMLHTTP activeX in IE, while using completely other objects in other browsers. Since this is the underlying mechanism used to perform RPC, it seems that if it happens for more than one of them, low chances that this is the cause. Still it seems that this MUST be the GWT/client code, since these clients, to whom this issue occurs much more often, don't have problems in any other websites (we managed to talk to several of them). One thing that comes to mind is perhaps the GWT serialization code? I don't know... Therefore, currently, aside from the possibility that there's a bug in the GWT serialization code, there's also the possibility that it's something in the network, even though these clients are from various ISPs, and geographical locations. Yes, I notice the dead end as well... These observations somewhat reduce the anticipated benefit (let alone the feasibility...) of several of your (MUCH APPRECIATED, THOUGH) suggestions: 1. ping from the lab 2. perl HTTP server Despite that, we ARE happy about any suggestion and willing to put the required effort, so we'll try to make progress in these direction. Our situation now is that we assume that the data arrives corrupted to the server, and we should see how this data comes out of the client. Therefore we will also try to install a sniffer in a client computer in which this occurs (though we have been trying to do that for quite a long time now).

servlet mapping, captcha and image...
I have a kaptcha which i have to define in my web.xml as
Kaptcha
/kaptcha.jpg
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 ?
Thx

Re: ListBox + FlexTable + How to maintain value in ListBox
Basically when the second time you click the list box, the onCellClicked of tablelistener is also getting executed, which re- initializes the listbox.

Hey all, - I've got a ListBox added to a cell in a FlexTable. - The FlexTable has a TableListener, and when the cell contain the ListBox is clicked, an RPC call is made that returns a collection of data used to populate the ListBox. - The ListBox has a ChangeListener, so that when the value is updated another ListBox in an adjacent cell is populated.

gwt-dnd and more help needed...
Hi, I have contacted the gwt-dnd group already. I am developing a web 2.0 product and I use gwt-dnd extensively. I am the only developer and I have a lot on my plate. The DnD section of the code works fine, but needs to be made better for a professional look. I am looking for a strong java/GWT developer with gwt-dnd experience ( or willing to learn - there is not much to it ) who likes doing the UI side of things ( not plain vanilla ui stuff - this stuff can be tricky ). I can explain compensation offline. This neednt be a full time job. It can be a long term relationship based on the work and interest. If interested, please send me an email at [EMAIL PROTECTED] Thanks -- pady --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: SecureRemoteService and Servlet. The battle against XSRF.
quentin: URLs aren't designed to be protected. At all. Cookies aren't exactly locked away in Fort Knox on your harddrive, but browsers at least have the good sense to understand that they shouldn't send arbitrary pieces in the cookiefile to arbitrary servers. Not so for URLs. To wit: 1) 'aggregator' websites such as Digg, Reddit, stumbleupon, and even just del.ico.us or just mailing a link around because you want to show 'something cool' to a friend, always grab the entire URL and spill this out to the world at large. This is obviously really really bad. One 'fix' is to make these sessions time out fast, but this annoys users, and having your account accessible by anyone following a story on an aggregator for 'just half an hour' is still pretty bad. 2) Referral. When browsing to another domain, your browser will add a Referrer: header which contains the URL that the user came from. This is handy for analysis flow on your own site, and to figure out where people are coming from when visiting your site. If you run a website and you're using google analytics or some other traffic analyser, you may have noticed a '% of traffic from google' indicator. This thing works by checking how many incoming requests have a Referrer: (www\.)? google\.com.* - this referrer system does not discriminate and will happily toss over the ENTIRE URL, which would include your session. I could -easily- make a webserver that'll check if it looks like there's a session ID in a URL, then report it and the website via chat to me, so I can quickly see if I can log in as this person. 3) Bookmarks. web-based bookmarking was covered in #1, but even a local bookmark is relatively bad, because in general bookmarks are far easier to leak to another person than your cookiefile. sharing bookmarks is actively encouraged by many browsers. No user except a real geek would cut his URL down to eliminate the session ID from it (and even more pathetic, if this geek does do that, using the bookmark is near useless because he'll have to log in again. d'oh). 4) It's a giant sore thumb that both says: Geez, I'm ugly, and: OMG, I have absolutely zip squat idea about web security, so whatever info you give to me, consider it yelled from the rooftops. Boy, my webmaster is a thick headed clot. Most other security leaks aren't nearly as visible, which isn't much comfort, but it does count for a little that this one is so obvious. Just look at the address bar. NB: Yes, yes, the official java servlet spec, even the very latest version, officially declares that URL rewriting is amongst the strategies. Sun evidently considers background compatibility with dangerous code more important than security, which, to say it mildly, / annoys/ me just a tad.

Re: Deferred binding based on annotation
Hi Ronald, It currently isn't possible to trigger a generator based on an annotation, but that is soon to change (see Issue #1206 linked below). The current way you could implement the functionality you're looking for would be to use a marker interface and an assignable-based generator to generate the given class. You can read about this on the GWT Developer Guide at the link below: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideDeferredBindingGenerators Issue #1206: http://code.google.com/p/google-web-toolkit/issues/detail?id=1206 Hope that helps, -Sumit Chandel On Thu, Nov 27, 2008 at 2:04 PM, rmuller <[EMAIL PROTECTED]> wrote: > > Hallo, > > Is it possible to trigger deferred binding based on an annotation, so: > > > > > > So you can use it like this: > Foo foo = GWT.create(class annotated by Baz) > > Regards, > > Ronald > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Unit Testing Generators - Best Practices?
I'm writing some unit tests for a Generator. The standard practice for handling errors in Generators seems to be to log an error message to the logger and then throw an UnableToCompleteException. Unit testing the proper handling of errors like these seems tricky for a couple reasons. Catching the UnableToCompleteException doesn't actually tell you anything about what error occured. Assuming multiple UnableToCompleteExceptions can be thrown in response to various error handling cases, some method is needed to verify that the proper error case was handled. My first reaction was just to subclass UnableToCompleteException with a specific exception type, but the documentation for UnableToCompleteException seems to imply that all error context should sent to the logger. Additionally, it seems likely that a higher-level error handler might consume any underlying exception thrown, log the high-level error and throw a new UnableToCompleteException, throwing awaythe underlying context. Any ideas? Best practices? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Eclipse issues
Hi I have some issues with Eclipse. 1.

Re: Client did not send nnn bytes as expected
Hi Amit, One other thing: I'm getting the impression that you also have a custom server. If it's an identical configuration across all server instances, than you also have to prove that it's not the server. Again, I'd code a simple HTTP server in Perl (because there's no problem so intractable that it can't be made worse with a Perl application) and use it to test against your application.

Record the output stats and run them through a formatting routine that will make it easier to check for problems. The goal here is to check end-to-end transmission w/o using application layer code. If this transmission failure happens every day, you should see something happen within 24 hours. If nothing untoward happens, it's (probably) the app. In that case, I'd grab a copy of Perl (or whatever you want) to write a client-side app that faithfully simulates your app's transmission profile. Point it at one of your servers and stress test that server/client circuit. Send PCs to several locations if you have to, but get something in the field that can reproduce this independently of your app and over which you have complete control. If that's not realistic, you'll need a "lab" environment, i.e. a machine that isn't a developer box, can be wiped clean and conveniently set to a known state.

Re: Your opinion sought: Jetty or Tomcat?
I've been mulling this over the past couple of weeks, and now I want to retract my initial objection about Jetty :) Mainly because, as Arthur and others pointed out, it's expected to speed up unit tests (which would be a huge win). And you don't need -noserver for most of the unit tests you might want to run - the default settings should be sufficient. Therefore this is one area where even the "-noserver" crowd can benefit from a faster embedded server.

Problem updating image URL
I have a custom button that has a couple of images as well as text.
My code is like this:
public class SplitButton extends Button
{
private IGWTImageBundle gwtImageBundle;
private final DockPanel dockPanel = new DockPanel();
private MenuBar menuBar;
private final Image image = new Image();
private final Label textLabel = new Label();
private PopupPanel popupPanel;
public SplitButton(IGWTImageBundle gwtImageBundle)
{
this(null, null, gwtImageBundle);
}
public SplitButton(String imageURL, String text, IGWTImageBundle
gwtImageBundle)
{
super();
this.gwtImageBundle = gwtImageBundle;
if (imageURL != null)
{
setImage(imageURL);
}
if (text != null)
{
setText(text);
}
initDockPanel();
}
private void initDockPanel()
{
dockPanel.add(image, DockPanel.WEST);
dockPanel.add(textLabel, DockPanel.CENTER);
dockPanel.add(gwtImageBundle.smallDownArrowIcon().createImage
(), DockPanel.EAST);
setHTML();
}
@Override
public void setText(String text)
{
textLabel.setText(text);
setHTML();
}
public void setImage(String imageURL)
{
image.setUrl(imageURL);
setHTML();
}
private void setHTML()
{
SimplePanel sp = new SimplePanel();
sp.add(dockPanel);
String test = DOM.getInnerHTML(sp.getElement());
this.setHTML(test);
}
}
The problem is calls to setImage(String imageURL) do not get updated
in the UI. That is, although the URL set is valid the image is not
shown in the button. The static image is shown in the UI however.
What am I doing wrong to set the image?

Re: How to configure GWT in existing application
Hi Arul, What are you attempting? If you want to replace your entire existing Struts/JSP based UI with GWT in one iteration but retain existing server-side services, then perhaps the easiest way is to replace your Action classes with GWT RPC servlet methods and just copy most of your Action.perform(..) code to these GWT RemoteServiceServlet methods (minus the JSP redirect and bean binding bits, plus preparing the beans for return to GWT client). Your application UI would then load and run from a single HTML file (which is optimal for GWT) and you can throw the old Struts stuff away. If on the other hand you want to (or must) either a) embed a bit of GWT sparkle into individual existing JSPs or b) incrementally replace JSPs over time, then the situation is more complicated. You need to explain your constraints and what you need to do. regards gregor On Dec 2, 1:56 pm, Arul <[EMAIL PROTECTED]> wrote: > Hi, > Want to replace existing presentaion layer alone by GWT. > Current application stores session value in servlet for processing in > JSP. > > The same way , How a GWT tool will be used to diplay those values > stored in session(servlet)? > > Thanks > Arul --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Exception while using Remote Services
Hi,
I am very new to GWT and have been followiung the GWT book by Packt
Publications. When ever i try to execute programs on Remote Services i get
exception- "Failed to load com.packtpub.gwtbook.samples.Sample"
I have the following in my project:
PrimesClient- Entry Point Class present in package
com.packtpub.gwtbook.samples.client
PrimeServiceImpl- Implementation for the Remote Service present in package
com.packtpub.gwtbook.samples.server
PrimesService- Synchronous Service class present in package
com.packtpub.gwtbook.samples.client
PrimeServiceAsync- Asnyncrhonous Service class present in package
com.packtpub.gwtbook.samples.client
And i have Samples.html
These are the series of error messages i get:
[ERROR] Could not find an asynchronous version for the service interface
com.packtpub.gwtbook.samples.client.PrimesService
[ERROR]
package com.packtpub.gwtbook.samples.client;
public interface PrimesServiceAsync {

Re: Easiest way to open a new window with some text in it?
nope..apperently I cant use a form panel to post data to a new

I'm happy to use any combination of php and gwt, but I cant seem to

I could save to cookie or something, but that seems a very messy

Re: How to design async widget
Hi Rexalo,
My 2c. What you seem to asking is if there is a standard "right" way
to do Model-View-Controller with GWT and/or what is the "best" way to,
as you put, "separate this transport/business layer from widget.". IMO
the answer is that there isn't a standard one, rather several options
or approaches. But I would search the group for "MVC" to get a flavour
of how many different opinions there are about this. Check this
discussion, for example, which is top of the list:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/6588acb2e9afe9d9/23f6dda583eaa44f?lnk=gst&q=MVC#23f6dda583eaa44f
IMO the difficulty is that both "Controller" and "Model" are slippery
concepts in an AJAX web application, whereas "View" is a straight
forward concept - it's a widget of some kind. Some reasons are:
1) The real "Controller" in an AJAX application is the browser -
anything involving a change to the DOM ultimately runs through its
event queue (and it also handles request dispatches and fields the
responses as well), therefore it is natural for Widget (i.e. view)
classes to interact with the browser event queue directly, and this is
what GWT does. Because GWT widgets catch, process and sink events
routinely anyway it is difficult (but not impossible) to separate them
from a separate "Controller" in a clean or meaningful way.
2) What might we mean when we refer to a "Model" maintained client-
side in a GWT application? Is it the "real" domain model for the
application, some sub-set of it, or maybe a snapshot of some some sub-
set of it? If you think about it, the "real" domain model resides on
the server and ultimately whatever sub-set of this is transported to
the GWT client must at some point be reconciled with the "real" server
model (i.e. the one actually persisted to backing store) always
bearing in mind that another client might have changed the "real"
model independently in the meantime.
Both these issues can introduce significant complexity. This is not to
say that there are not sometimes good reasons to introduce
"Controllers" and "Models" client side. An example might be a chat
application that uses blocking requests (i.e. comet style) to pick up
new messages. But it does imply that doing so introduces layers of
complexity to a GWT application that may be unnecessary.
For these reasons I don't think it is automatically the case that "i
want to separate this transport/business layer from widget" is a
necessarily a good design/engineering decision in a GWT app. What
works simplest usually works best. However, sometimes it is and there
are several approaches to doing it - it depends on what you are
actually trying to achieve, not on a matter of (MVC) principle.

gregor

Couple of questions regarding getModuleBaseURL()
How can I determine what GWT.getModuleBaseURL() will return on the server? I want to build a URL, on the server, and send it to the client. I would prefer this URL to be complete and not rely on the client making this method call. Is this possible? Also is it possible to know what file system path getModuleBaseURL() refers to? I need to copy some dynamically created images to a folder under the HTTP root folder.

How about doing your setName like this:

String old = getFirstName();
setFirstNameImpl(firstName);
changes.firePropertyChange("firstName", old, firstName);

? Yes, it take an extra method to jump into the JSNI, but the compiler will
erase that indirection anyway when it builds the JavaScript. Your only
penalty is the slightly longer code to write for each bound property method.

JSON Mashups
Hello guys,
Currently I'm trying to use JSON mashups in my application, but I'm
falling on an issue with the binding and validation of the data objects.
In another web project I was used simple POJO objects and the binding
was implemented in this way:
public void setFirstName(String firstName) {
String old = this.firstName;
this.firstName = firstName;
changes.firePropertyChange("firstName", old, firstName);
}
And here is the question, how can I do this with JavaScriptObjects when
my method stubs are looking like:
public final native String getName() /*-{ return this.name; }-*/;
public final native void setName(String name) /*-{ this.name = name; }-*/;
Probably I have to use some JSNI magic :).
Does anyone have an idea how to do this ?. Or some better solution for
binding and validation of such an objects.
Thanks in advance
Regards,
Miroslav

Re: fundamental design question on font size
Hi, GWT can only do so much w/r/t/ these kinds of design issues. Do you use fixed font metrics (pt, px) or do you use %? The latter will handle different font sizes, but it does require that you avoid "complex" screen layouts. Getting font metrics isn't hard, but if you want to get "fancy" you have to be quite aware of widget layout. It may also be that GWT is wrong tool to use, and you need more control over the display (i.e. Flash) On Dec 2, 6:17 am, mryilauer <[EMAIL PROTECTED]> wrote: > What am I doing wrong?

Are you quizzing us or asking for help? I would go with alex.d 's solution. Other method(which I personally hate) is to write a for loop in the onClick event of the button that will read the widget in each r,c and match it with the "sender" or button instance itself.

Re: SecureRemoteService and Servlet. The battle against XSRF.
Yes, you could definitely do that to merely access your session but
that doesn't do anything to help prevent XSRF. Here's a great article
all about this which includes what I mentioned earlier about sending
the identifier as a header.
http://groups.google.com/group/Google-Web-Toolkit/web/security-for-gwt-applications
The article is a little dated since you can now get at the Request or
RequestBuilder objects for the GWT-RPC requests and set the headers.
This page explains how to get at the Async's underlying Request and
RequestBuilder objects

Is GWT is good alternative for replacing presentaion layer alone?

fundamental design question on font size
What am I doing wrong? I am building widgets for use throughout the organization, and when I try to generalize everything, it always seems like I always need access to the font metrics so I can adjust positions of widgets based on the user's font size. I have read the posts about font metrics, but I am not asking how to do this as much as I am asking: if getting the font metrics is hard to do, what should I change in my approach to design so that I don't need them? Apparently, gwt itself must be getting along without this if an easy way to get it isn't built in, so there must be something wrong in my approach that always leads me to the place where I think I need to know the 'm' size of the current font. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Server Push with GWTEventService
Quote from the annoucement : The first public version is v0.9. All features for version v1.0 are contained and I hope many developers are interested and will use and test the framework in their applications, so that v1.0 can be reached soon. GWTEventService is an event-based client-server communication framework. The client side offers a high-level API with opportunities to register listeners to the remote server like to a GUI component. GWTEventService can be used to resolve "old-style" polling calls in GWT applications with a clean and extensible architecture. It looks nice, easy to use and well documented : http://code.google.com/p/gwteventservice/ Did someone try it ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to design async widget
Hi, Gregor!
Thanks forreply.
I understand that i can't simply use rpc call right in widget event
handler,
but i want to separate this transport/business layer from widget.
My widget simply shows list of items of some class(Group) and provide
control elements
to manupulate them: edit, delete, add etc.
I am simply interested in a approach. maybe there is some standart way
advices
For now - i provide two methods for widget client -
void add(Group)
void onAdd/onSuccessAdd(Group)
maybe there is some more cultural way ? =)

How to overcome this warning (upgrading issue)?
Hey,
I want to upgrade my GWT application from GWT 1.4.6 to GWT 1.5.3
What I'm facing is this warning:
[WARN] 'mydomain.UsersList' is not a generic type; only generic types
can be parameterized
com.google.gwt.core.ext.typeinfo.BadTypeArgsException:
'mydomain.UsersList' is not a generic type; only generic types can be
parameterized
Here is my code:
//In the RPC interface
/**
* * @gwt.typeArgs
*/
public UsersList loadUsers(int start);
public class UsersList implements IsSerializable {
private List users;
Would you please tell me how to overcome this?
Thanks for your time.

Re: SecureRemoteService and Servlet. The battle against XSRF.
Answers to gregor, Patrick, and quentin in this post.
Hey gregor -
some coward has probably taken exception to some light hearted ribbing
and instead of either playing ball or doing something vaguely
constructive, such as asking Sumit to protect his honour for him, he
instead did a search for my name to vote everything I've recently
written a 1-star, presumably because this act of revenge makes him or
her feel better. Chances are these posts were voted on without even
reading them. I therefore doubt it's got anything to do with my
security advice itself. Possibly the way I've been expressing it.
This certainly isn't the first time it happened.
Patrick:
Mea culpa - for some reason I was thinking that the objects tossed
across the wire had to wrapped in RPC interfaces and '-Async' classes.
Its actually the servlets that have to be. I don't see an easy way to
generify this. Seems like adding 'sessionID' as a parameter to -every-
-single- RFC-accessible method is required to make this work right. I
would at least make an easy method to fish the sessionID out of a
cookie+cache it on the client, and I'd make an easy method on the
server side to check it.
Client:
public class XSRF {
private static String sessionId;
public static String getSessionId() {
if ( sessionId == null ) sessionId = Cookies.getCookie
("jsessionid");
//the actual name of the cookie depends on your web stack.
//Just get all cookies and print their names to figure this
out, then hardcode it.
}
}
and on the server, add a method that does what I'm going to answer to
quentin:
quentin:
There's a slight risk you forget to check. It would certainly be an
excellent plan if your webstack supports plugging into it, adding that
check. (or if it doesn't, just hack it in - all hail Open Source as
the one true way for libraries). For reasons that aren't too
interesting, the apps I've written so far had other session
constraints which meant I re-invented the wheel anyway. However, I did
some checking and it turns out your strategy seems easiest - the
latest servlet spec makes it rather hard to query the session system
with a given ID.
To be a bit more verbose:
HttpSession session = request.getSession();
if ( !session.isNew() ) {
if ( !session.getId().equals
(sessionIDPassedInExplicitlyBySender) ) {
//XSRF detected.
response.sendError(response.SC_FORBIDDEN, "Whups. If you're
seeing this, please contact us.");
return;
}
}
jossey: Reread the entire thread. The servlet spec's own session
system is spectacularly stupid. It is either XSRF-unsafe and uses
cookies, or it is blatantly unsafe and stuffs session IDs in the URL
(I *STILL* see this in modern webapps - check for ;jessionid appended
to the URL, bizarre considering that security gurus have explained the
problem with this approach for over 5 years now). If it does use
cookies, it won't protect against XSRF, basically because you can't do
that without relying on javascript. Fortunately, using GWT means
you've already accepted that your users MUST have javascript up, so we
GWT users can solve XSRF the easy way, with javascript.

I doubt that there is a bug in the lower levels of an OS that lead to the truncation of TCP-packets only when they come from a GWT- application being executed inside an Internet Explorer. With the sniffed packets I was hoping to see a pattern (if the application is calling function x, y and z the effect starts to be observed, etc.) With that you might be able to reproduce the effect on a local machine allowing you to initiate further actions like installing a sniffer on that box to see if the packets are sent truncated or why the IE is getting a hickup.

Re: How to design async widget
Hi Relaxo,
The simplest way is to make your RPC call from addBtn.onClick() using
an anonymous Callback where this callback's onSuccess(..) method adds
the new Group List groups and changes the view as required.
There may be reasons why this would not meet your requirements, but it
is not possible to say from your example, i.e. on the face of it you
do not need the controller interface. There isn't a single "right" way
to do asynchronous RPC - it is possible to over-engineer it and
equally it's possible to under-engineer it.
If in fact your situation is more complicated than the example
(leading to a motivation for using this controller interface),
probably best to give some idea of the overall problem to get further
advice and options (of which there are several).
regards
gregor
