Re: GWT-Gadget same-origin security restriction

Getting continued feedback on the state of a RPC call
Hi all, I have a GWT application which uses a remote service that does some complex, and potentially long work. However, I don't want to hold the user unaware of the status of their request for too long. So I would like a way for the client app to receive frequent information on the service status, which would be posted to the UI in real time. I've unsuccessfully tried the following way: The client makes a call to the remote service, which starts doing its job. The service itself, in turn, modifies some state variable during the course of its computation. So I created a client-side Timer which, every second, polls another remote service that simply returns this state variable. This timer is started right before the main service is called, and is halted after the service returns. Being these calls asynchronous, this method didn't work. All scheduled Timer calls returned after the main service altogether. I know it might be a dumb question, but it would really be helpful for me to be able to provide the user with continued feedback on the state of the service they called.

JavaScript error only in Hosted Mode
Hello.
I've run into something that I think is a limitation in the GWT hosted
mode browser.
In javascript includes, it seems that they don't have the Window
object defined.
I included a javascript file (By putting a script tag in the gwt.xml),
let's say Test.js, and wrote the following into it:
function T(f) {
f instanceof Window;
}
and then in a JSNI method called $wnd.T(something)
This throws the error in GWT Can't find variable: Window.
The same setup seems to work in Firefox. I haven't been able to test
the exact same circumstances in Firefox, because the errors in Hosted
Mode stop me from being able to compile and browse in something else,
but a simple HTML file and js include seems to work in Firefox.
If I've misunderstood something, that would be great.
Any help would be appreciated.

Moving values

When I give any values in the textfield and select the button means, that text box value should come below the trash in Mail tab at right hand side. I have tried it many ways, the values are reaching the Mail tab, but it not placing below the trash. Then all the calls are ajax call.

Also, the client in the apache axis package path is not the same as

Can you show us the import sections of your client java files?

Possible to split GWT application in seperate WAR files?
Hello, i have a question related to packaging a larger business application. I am building a GWT application that contains two parts, a generic part and a customer specific part that will be changed for every customer. Both parts depend on each other and shall be integrated into one big application. A major requirement is that the generic part shall be developed and deployable independently from the customer specific part. If we for example discover a bug or add features to the generic part we want to deliver an archive (WAR file) to the customer without touching the customer specific part (in some cases we even won't have access to the customer specific part. As far as I know so far, it is possible to create two seperate modules where the customer specific modules inherits the generic module. So I have an idependance at source level. But when I compile the customer specific module, both modules are compiled into one folder. Is it possible to separate the two modules and package them into separate WAR files? Is there any other way to integrate two modules so that the can be developed and deployed independently? Many thanks in advance.

Re: GWT spring integration
A not very sophisticated solution, but doesn't need much explanation
and gets you debugging how you want is a simple proxy servlet for each

public class PortfolioServiceProxyServlet extends RemoteServiceServlet
implements RemotePortfolioService {
// Reference to spring managed bean.
// The interface PortfolioService extends the interface
RemotePortfolioService.
private PortfolioService service;
public PortfolioServiceProxyServlet() {
super();
// Get a Spring application context.

String[] s = {applicationContext.xml};
ApplicationContext context = new

// Get a reference to the Spring managed bean.
service = (PortfolioService)
context.getBean(portfolioService);
}
public Portfolio getPortfolioById(Integer id) throws Exception {
try {
// Forward to the spring managed bean.
return service.getPortfolioById(id);
} catch (Exception e) {

throw new Exception(e);

Re: Getting continued feedback on the state of a RPC call
Hi, Event I am a newbie in java and GWt, though how about partitioning your long job, as in... e.g. For a http call which needs to access names say 100,000 in number. I might actually partition this call in say 26 calls with each call querying names starting with each of the 26 alphabets... and on the callback of the first function I might update the user and make the second call and so on. Actually do a chaining... :) Thats just a guess... may be that I might be totally wrong on this... :) Cheers, Amit Dhingra On Tue, Sep 23, 2008 at 3:19 PM, Palietta [EMAIL PROTECTED] wrote: Hi all, I have a GWT application which uses a remote service that does some complex, and potentially long work.

Re: Sharing the localization code between client and server
Hi, I am also interested in this. Our approach is to write the texts into the properties files and then use the GWT-i18n tool to generate the interface-files. Of course this is not the best thing to do, because all the arguments will be strings... Maybe another approach would be to extend the GWT-i18n tool, which already does the properties file parsing and creates the interface file. I have not looked at this tool yet, but maybe it can be extended to generate another file for the backend, that implements the interface methods and builds the messages from the ResourceBundle. regards, martin On Sep 22, 12:02 pm, Lothar Kimmeringer [EMAIL PROTECTED] wrote: Dobes schrieb: Hm, I see.

Using GWT.create will be difficult on the server-side, because the Locale can be different for every request, so you need a second parameter. Using ResourceBundle on the other side allows a similar call: ResourceBundle rb = ResourceBundle.getBundle(AdminToolsI18NConstants.class.getName(), loc); I suppose not, so maybe I'd have to come up with some kind of clever factory scheme which uses GWT.create in client code and whatever my own implementation is in server code. You can implement your own version of ResourceBundle, that is reading in the property-files and use reflection on the interface to get the annotations. With Proxy-classes it should also be possible to create something similar to GWT.create. If I have very much time, I'd might be able to program something like this, but you shouldn't wait for that, at the moment my spare time is about zero ;-) Regards, Lothar --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Claude, Wouldn't that web service be returning you a huge steaming pile of SOAP XML? I think that would be a nightmare to try to deal with in a GWT client.

Re: Possible to split GWT application in seperate WAR files?
Hi, I think the answer is 'no', although there may be work in the pipelines to address late binding among GWT modules (I don't track that). However, from a configuration management POV, what you are proposing makes no sense because you will need to do integration testing of the new configuration consisting of an unmodified module A and a modified module B. If you don't do that testing, then your production environment will be in an unkown configuration (i.e., technically broken). If you do do that testing, then you will have had opportunity to package the entire new configuration, which might as well be a monolilthic build as not. So where's the advantage?

Re: Opening and Loading a GWT Module from another module
GWT is not Java; it doesn't have dynamic class loading. Maybe someday. In the interim, is there a way to describe your goal without making technology assumptions like this? Maybe there is a way to get the behavior you want using GWT in its current form, but you'll need to say more. Also, the in a new Window is not usually the best way to design with GWT.

url parameters
Hi, I am building a gwt web app in which users can ask for a navigation route between two points. The coordinates of the points are stored in a database so the user only has to provide two names. The names of the points are also available from a portal that we developed and contains information about these geopoints I was wondering if it is possible to pass the departure and destination names as url parameters to my gwt app, so as to show the route immediately without having to provide them throught the appplication ui.

Re: Opening and Loading a GWT Module from another module
Hi Walden, My purpose is to view an image that is uploaded in the same session without having to refresh the whole page. I was searching for a way to view the image but I could not view any image that is uploaded in the session that I am trying to view it in. I am getting the error file not found. If you have any idea how I can solve this issue, I will appreciate it. Thank you. On Sep 23, 4:15 pm, walden [EMAIL PROTECTED] wrote: GWT is not Java; it doesn't have dynamic class loading.

Re: url parameters
The GWT widget library (http://gwt-widget.sourceforge.net) provides
this functionality. You simply say:
String departure =
WindowUtils.getLocation().getParameter(departure);
If you don't want to use the GWTWL, then you can parse the URL
yourself. First create a native method to get access to the page's
URL and parse out the parameters you need. Here's an example of a
native method that can do that for you:
public static native String getURL() /*-{
return $wnd.location.href;
}-*/;
The just use indexOf() and substring() to do the parsing...

problem with multiple fileupload in GWT 1.5
In GWT 1.5 I have an implementation like: http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/FileUpload.html The difference is that I have 2 FileUpload entries, instead of 1: final FileUpload fileUploadDataset = new FileUpload(); fileUploadDataset.setName(fileUploadDataset); verticalPanel.add(fileUploadDataset); final FileUpload fileUploadMetadata = new FileUpload(); fileUploadDataset.setName(fileUploadMetadata); verticalPanel.add(fileUploadMetadata); On the server I only receive 1 file (the first). This was working fine in GWT 1.4 but not in GWT 1.5. Any idea what could be my mistake?

Re: Sharing the localization code between client and server
It seems like it should be possible to implement a kind of server-side GWT.create() that generates an subclass using cglib or one of the other bytecode generators. Maybe it would only work for the Constants and Messages interfaces, and a minor selection of others, but it would be quite useful. Unfortunately, it would be difficult to implement this outside of GWT because the client code a) can't use any classes not supported by GWT and b) must use GWT.create with a literal class (not a variable) as the parameter.

Re: how to clear cache on windows hosted mode
Hi Ian, Thanks for the response; I am on Windows. To be more specific, I'm pulling data in from another server via JSONP in the manner described in this article: http://code.google.com/support/bin/answer.py?answer=65632topic=11368 I've found that the script tag content tends to be cached by IE. I just retried deleting the cache in IE browser and that did the trick--the hosted browser pulled the script tag content on refresh. Dan PS The gods of the cache! Classic. Sometimes it sure does feel as if caching is ruled by capricious deities. On Sep 23, 12:28 pm, Ian Bambury [EMAIL PROTECTED] wrote: It does rather depend what you think is being cached and why. For exanple, if you are changing a file to UTF-8, you need to make a change in that file so GWT will know to recompile that class, but, you can try all or any of these (I'm assuming because of the IE reference, you are on Windows): 1) Highlight the project in Eclipse and hit F5 to ensure that Eclipse is in sync with the file system 2) Project | Clean to rebuild the project (useful if you have flagged errors you know aren't errors) 3) Delete the IE cache 4) Delete the bin/tomcat/www directories in the project (and also any other project which uses the same package names) 5) In the problem class, add a space somewhere (or take the space away - anything to flag the file as changed). 6) Restart Eclipse (this is a 'what the hell else is there to try' measure for me, as is a reboot) 7) Sacrifice something to the gods of the cache.

The service itself, in turn, modifies some state variable during the course of its computation. So I created a client-side Timer which, every second, polls another remote service that simply returns this state variable. This timer is started right before the main service is called, and is halted after the service returns. Being these calls asynchronous, this method didn't work. All scheduled Timer calls returned after the main service altogether. I know it might be a dumb question, but it would really be helpful for me to be able to provide the user with continued feedback on the state of the service they called.

I'm using your software and I would add a simple zoom tool with mouse
selection
I need to know the exact position of axis origin (left bottom) to
transform x,y mouse in chart's coordinates
here my code
after
sinkEvents(Event.ONMOUSEMOVE|Event.ONMOUSEDOWN|
Event.ONMOUSEUP);
I tried to calculate the origin
public void onBrowserEvent(Event event) {
double x;
double y;
double mouseX=event.getClientX()-getAbsoluteLeft();
double
mouseY=getAbsoluteTop()+getOffsetHeight()-event.getClientY();
Axis xAxis = getXAxis();
Axis yAxis = getYAxis();
double dx=xAxis.getAxisLabelThickness() +
xAxis.getTickLabelThickness() + xAxis.getTickLength();
double dy=yAxis.getAxisLabelThickness() +
yAxis.getTickLabelThickness() + yAxis.getTickLength();
x=mouseX-dx;
y=mouseY-dy;
// transform in chart coordinates
x=xmin+x*(xmax-xmin)/getXChartSize();
y=ymin+y*(ymax-ymin)/getYChartSize();
I'm on the right way or there is a simpler method?
thanks
Albert

Client-sideGChartis an open source GWT library that supports bar,
line, and pie charts, and yet adds nothing but its ~2,000 lines of
Java to your application's list of dependencies:
http://gchart.googlecode.com
This 2.2 release adds:
* A new LINE symbol type for faster/better solidly connected line
charts
* A new layout algorithm that centers title, footnotes, axis labels
and legend within explicitly-sizable bands around the plot area. In
particular, since these bands have default thicknesses of 0px when
empty, Sparkline charts are now straightforward.
For full details, including links to example charts illustrating the
new features, see theGChart2.2 release notes:
http://gchart.googlecode.com/svn/trunk/doc/com/googlecode/gchart/clie...
Related posts/acknowledgments:
1) This post by Niall Haslam motivated the much-needed switch to a new
chart decoration layout algorithm:
http://groups.google.com/group/Google-Web-Toolkit/msg/5be9867eb81c9ca4
2) I used the technique explained in this post by Ian Bambury
(http://examples.roughian.com) to workaround a perplexing IE7-only
screen-not-repainting problem that the revisions of this release
inadvertently exposed:
http://groups.google.com/group/Google-Web-Toolkit/msg/31b2d8e0eace6f3c
3) The improved line chart capabilities were motivated by the far-too-
slowly-updating solidly connected line chart code that Malcolm Gorman
sent me. A new live demo chart, deliberately (HTML-element) sized
similarly to Malcolm's chart, illustrates various ways (smaller
charts, lower resolution connecting lines) you can use the new LINE
symbol type to workaround the significant performance limitations that
still remain for this kind of non-rectangle-friendly chart.
Your ideas for improving Client-sideGChartand help in solving its
implementation problems were essential to this 2.2 release. Thank-you.

Memory Leak in IE 7 using GWT
We have an app that uses GWT with large HTML content (60-70 K) that produces large memory leaks (2-3 M) in IE 7. It does not exhibit the same behavior in Firefox (memory goes up with multiple document loads, but goes back down after a few seconds of inactivity). We have looked at the app with the JS memory leak detector which is reporting many memory leaks. This tool reports similar memory leaks for the kitchen sink example. Are these real or is there something about the GWT code that JS doesn't understand? We know that we are leaking memory that requires browser shutdown to reclaim, but the bulk of the leaks reported by JS seem to be gui components that don't result in significant memory usage. Has anyone else experienced this? How did you solve the problem?

Re: Sharing the localization code between client and server
Dobes schrieb:
It seems like it should be possible to implement a kind of server-side
GWT.create() that generates an subclass using cglib or one of the
other bytecode generators.
Actually I think you can do that with the functionality of
the JVM itself using Proxies:
--
public interface MyConstants implements Messages{
public String LocalizedMessage(String argument);
}
--
public class MyConstantsProxy implements java.lang.reflect.InvocationHandler{
private ResourceBundle rb;
public MyConstantsProxy(ResourceBundle rb){
this.rb = rb;
}
public Object invoke(Object proxy, Method method, Object[] args) throws
Throwable {
String value = rb.getString(method.getName());
for (int i = 0; args != null i args.length; i++){
if (args[i] == null) continue;
value = value.replaceAll(\\{ + i + \\}, args[i].toString());
}
return value;
}
}
--
To use the proxy you have to get the resource-bundle and create the
proxy, so an imaginary GWT.create-method might look like the following:
--
public static Object create(Class clazz, Locale loc){
ResourceBundle rb = ResourceBundle.getBundle(clazz.getName(), loc);
MyConstants constants = (MyConstants) Proxy.newProxyInstance(
getClass().getClassLoader(), new Class[]{MyConstants.class},
new MyConstantsProxy(rb));
}
--
And use the method normally:
MyConstants constants = (MyConstants) GWT.create(MyConstants.class,
new Locale(de, DE));
System.out.println(constants.LocalizedMessage(this is the message));
Maybe it would only work for the Constants
and Messages interfaces, and a minor selection of others, but it would
be quite useful.
I think restricting it to Messages and Constants is OK because
these two are the only ones anyway where the special behavior
of GWT.create is used.
Unfortunately, it would be difficult to implement
this outside of GWT because the client code a) can't use any classes
not supported by GWT and b) must use GWT.create with a literal class
(not a variable) as the parameter.
The skeleton above should work and is not in conflict with the
current concept of GWT. You need the second parameter because
you must be able to get different classes in dependence from
the Locale being set on the client.
The only thing missing is implementing your own version of
ResourceBundle with the same algorithm for deciding which
property-file to be used in dependence to the requested Locale
(no use of System-Locale but directly fall back to the main
property-file, wrong default Locales for EN and ES, etc.)
and UTF-8 to be used as encoding. The latter can be done
by using Properties.load(Reader) implementing all the methods
of ResourceBundle or write an InputStream that is reading in
the data as UTF-8 and converts all non-8859_1-characters to
the escaped sequence being accepted by Properties. Other
things like caching of created proxies, support of the
annotations that came with GWT 1.5 etc. IMHO can be added later.
And that's the part where I don't have the time at the moment. ;-)

need help to refresh frame using javascript function
Hi, I have 3 frames added on one panel, again that panel is added on Viewport(GWT-Ext). I want to refresh frame using JSNI or javascript function. Normally, we use top.headerFrame.location.href=top.headerFrame.location; for frame (ie. named headerFrame in this code) that is directly added to html page. But this is not working on GWT. cos, in GWT we need panel as one media to add widget. Is it? So, please teach me how to access frame inside panel to refresh using javascript code. Thanks in advance. I already tried with this code. It's working. Frame tFrame = new Frame(); String frameUrl = tFrame.getUrl(); tFrame.setUrl(frameUrl); I want the javascript funtion to refresh GWT frame similar to top.headerFrame.location.href=top.headerFrame.location; . Hope reply as soon as possible. I tried to search the solution over 1 week :-(.

[gwt-contrib] Re: RR: 1.6 Event handler proposal
I completely agree that it is important to find a better solution to the irritating cross-browser differences in keyboard event handling, and I'd really like to discuss that on a separate thread (starting such a thread right now would be perfectly fine by me -- I just don't want to confuse the issue by discussing too many things on one thread). The goal of this design is to simplify and normalize the way that widget-level events are structured. So we could really use feedback on the way that events are registered and handled, the mechanism for storing and firing sets of listeners, and the way in which new widgets use them. We're planning on moving everything to this structure (with shims for backwards-compatibility), so again your feedback would be helpful. Thanks, joel.

I also like the idea of a logical key event that is only fired at sane times if you have the bandwidth to brain storm on how to tweak your design to get it there. We could, for instance have a static FilterKeyEvent.fireEvent method that widgets could call which create FilterKeyEvent's at the right time.

[gwt-contrib] Re: Safari Empty History Tokens
Wow, that's about the freakiest thing I've seen in a while. The fact that
the following code fails is really disturbing:
private static boolean isBorked() {
Element e = DOM.createDiv();
e.setInnerHTML(spoo);
return e.getInnerHTML().length() == 0;
}
I also tried taking the History.newItem() calls out of onModuleLoad() and
performing them in response to a button click (just in case it was in a
weird state during module init), but it still does the same thing.
This might be related to issue 2909 as well. I'm working on figuring out
what's going on here, so if anyone has any ideas please speak up!
(can you tell that I really want these History issues to go away once and
for all?)
Cheers,
joel.

Removing the synchronous calls for empty tokens works around the Safari

Seems a bit weirder actually: using the previous button, go back to
#x then forward (back to the enmpty token) and it'll show History
OK.
Yes - those invocations of the history listeners are due to the history
timer - not synchronous calls in HistoryImpl#newItem.
And it's working OK in Chrome (0.2.149.30).
I think the problem has to do with the immediate history processing.
Probably. Though, the immediate processing isn't precisely
documented, so i'd say you shouldn't rely on it ;-)
I'm not relying on immediate processing. This bug is triggered by
immediate history processing.
