Re: How to Authenticate Uploaded file format, size at the GWT client side?
It is NOT possible to do anything with files using javascript, so Gwt
has nothing to do with files in client side.
So, I recommend you to do this:
- Use gwtupload library http://code.google.com/p/gwtupload/
- At server side extend UploadAction, and write your own file
validations (you can do it when the upload finishes or during the
transmission) using everything available in the java world.
- If the file doesn't match your requirements throw an
UploadActionException, so that the client side will mark the upload as
unsuccessful and will alert the user.
Cheers

Green IT
In common Green IT will seen as a hardware issue. However, when you are comparing GWT / AJAX - application with classical web technologies like JSP, JSF, PHP you will detect that these technologie heavily differs in power consumptions, too. - GWT reduces the load of the servers. - GWT reduces the load of the clients - GWT reduces the load of the network All this will save power and thatfore GWT is also a big contribution to green IT. My personell expectations is that switching from classical web technologies to GWT could save 90% of power consumption. Does someone know of a concrete investigation of this topic?

Re: ant hosted not working on my machine ...debugging is very tedious
Thanks for your reply. For some reson cutpasting the url in Opera does not work. In fact my Opera version just shows a blank page.

Re: 1.7 to 2.0, GWT doesn't work any more
I found the solution. It was that the AbsolutePanel in 1.7 didn't need to be sized, in 2.0 it does (I think it defaults at 0,0 when using GWT 2.0). There are other differences in appearance from my 1.7 app too, which I'm working through.

Re: GWT with GAE Blobstore
you cannot use RPC to upload files as i may know.
when uploading you need to submit a HTML form.

Re: Can we check uploaded file Size at client side in GWT by Reading the "header info" of the file
You can't, and you don't want to. You can't, because javascript doesn't provide any way to read the contents of a file that is stored locally. You can't read the http header info when the browser submits a multi-part post request. There just isn't a way to do it (unless you are willing to write some Flex code to compile a SWF file for Flash Player 10).. You don't want to, because client side validation is no validation. It can easily be bypassed. You'd have to perform the check on the server anyways, so why bother with client side validation at all? --Sri On 11 May 2010 16:48, GWT Groups wrote: > > Hello Friends > > I required your views.. > > " Can we check uploaded file Size at client side in GWT by Reading the > "header info" of the file?

Is there a way to get these things working in GWT 2.0? I've found that gwt-diagrams2 works when deleting from the html file, but other things don't work then! Would anybody recommend me going back to GWT 1.7? Many thanks, N -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Note that you can write Window.Location.replace(url) to the same
effect.

The browser is just resolving the URL reference relative to the URL of
the *calling* browser context (in this case, the .cache.html,
which is loaded in a hidden iframe).
To fix this you just have to use an "absolute path", which you can
easily construct using GWT.getHostPageBaseURL(). For instance:
Window.Location.replace(GWT.getHostPageBaseURL() + "login.jsp");

Re: Can we check uploaded file Size at client side in GWT by Reading the "header info" of the file
Because it is a much better user experience to show an error message right away rather than letting the user wait for a long time and then telling him the upload has failed.

Re: GWT issue when browser offline
Hey I know that in offline mode the browser doesn't access server, what I was asking is how will the user know about this, by user I mean the end user and not the developer.

RadioButton detect value change when deselection is automatic
I'm trying to customize some radio buttons in GWT, but i cannot execute operation when value is change by selecting other buttons in the same group. It seams that onValueChange is not triggered for those radio buttons that loose their value (automatic deselection) when a certain radio button in the same group is pressed. So is there a way of detecting that ? or make the method trigger for the widget that looses value ? (i need that to set an image). I also tried checking the value when at focus or blur, but if the "input" tag is not displayed (i need to hide that to display my own selection images), the onBlur, onFocus methods are not called. I'm i doing smth wrong ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: help for sending e-mail using rpc / gwt
Hi Felipe,
RPC implementation would be simple. Just write an ordinary
RemoteServiceServlet and write a function to pass a String parameter (or a
Vo) with the emailBody to the ServiceImpl code. From ServiceImpl, you can
use the code below to send the email.
Let me know if this answers your question.
Regards,
Abhi

Re: RadioButton detect value change when deselection is automatic
You need to track ValueChangeEvents for all radio buttons in the group, and remember which radio button is currently selected at all times. If you do that, then every time you see one radio button in the group becoming selected, you know that the radio button that was previously selected just became unselected. http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/RadioButton.html "Note, however, that browser limitations prevent ValueChangeEvents from being sent when the radio button is cleared as a side effect of another in the group being clicked."

ImageSpriting now working in mobile Safari? gwt + phonegap
Im building a phonegap Application with GWT and started switching my
css files to ClientBundles and ImageSpriting with GWT 2.0
the css file looked something like:
@sprite #someId {
gwt-image: "headerMiddle";
position: relative;
height: 40px;
border-bottom: 1px solid rgb(45, 54, 66);
}
And the BundleInterface looks like:
public interface HeaderPanelResourceBundle extends ClientBundle{
public static final HeaderPanelResourceBundle INSTANCE =
GWT.create(HeaderPanelResourceBundle.class);
@ImageResource.ImageOptions(repeatStyle =
ImageResource.RepeatStyle.Horizontal)
@ClientBundle.Source("org/dvelop/phonegap/iphone/public/img/
header_middle.png")
ImageResource headerMiddle();
@ClientBundle.Source("org/dvelop/phonegap/iphone/public/css/
headerPanel.css")
HeaderPanelCss css();
}
Everything works fine in Desktop Safari 4.0.5. If I remove the
spriting and replace it with a simple background-image everythings
fine again. Not only the sprinting style is broken all other styles in
the css file as well.
Anyone experienced something like that before?

Re: new GWT MVP article (part 2)
The increased complexity is definitely an issue. I don't like the idea of yet more interfaces to have to worry about. It's a shame that part 2 of the MVP article doesn't address testing beyond simply mentioning that these practices improve testability. It would be much clearer to see before-and-after code highlighting the code that we want to be testable in both cases. Without that, it's hard to convince someone that the extra complexity is worthwhile. I'm currently working on a small application using UiBinder (and hopefully GIN) without MVP. It's giving me a refreshing perspective on how fluent GWT can be, and I think the people I work with will appreciate that. However, it's not going to be any more testable than any other web technology we've used. >From there, I'm going to go about refactoring the code to make it more testable. This will probably involve applying MVP-like patterns, but I'm going to try to apply patterns that make sense and not be too biased by existing examples. I may end up with something much like what the GWT team is suggesting, or I may find some middle ground, but I should at least have a good feel for what I'm getting in return for the increased complexity. -Brian On May 11, 1:24 am, dayre wrote: > I could comprehend part I after watching Ray's presentation and > reading it a few times... it gave me a much better idea on how to > structure my application, but part II things started to fall apart for > me.

Placing xxx.ui.xml files in different packages than counterpart Java files
Hi,
Does anyone know if there is a way to place the ui.xml files in a
separate from its Java counterpart file package?
What I have to have is essentially the following package structure:
view - All Java uibinder classes
view.uibinder - All .ui.xml files
view.uibinder.resources - All .css files.
I found the @UiTemplate annotation that allowed me to successfully
move the ui.xml files into the view.uibinder package and just refer to
those in the Java file with @UiTemplate("uibinder/someView.ui.xml").
Unfortunately, all the references to the resources, although showing
no errors in Eclipse, start breaking on GWT compile. So, for example,
if I have the following in my ui.xml:
When compiled, the error says that it can't find the style when lookin
in view/resources/styles.css. Note the lack of "uibinder" directory in
the error message!
Upon further testing, it seems clear that when the ui.xml files gets
ingested into its Java counter part, it copies that 'src' path
verbatum, without adjusting it first. I know this because if I put "../
resources/style.css", the error message will come with that it can't
find the path and show that it's looking in "view/../resources/
style.css"
Is there some annotation or some flag I am supposed to provide to get
this to work or is the location of the .ui.xml file forever stuck with
the location of its counterpart Java file?
Thanks,
Yaakov.

UiBinder + CSS layouting
Hello! I'm wondering if anybody has a good way of handling the very time consuming job of fixing the CSS when using UiBinder. Since we started using UiBinder (which I really like, by the way) we've had to start re- running the app whenever we want to make a change to the CSS. Resulting in extremely bothersome change-rerun-check cycles whenever layout is to be changed. I can't really just check the HTML file in the browser without running the application either, because for some reason images don't load when doing that. Any way to make images load before the GWT app? Regards, Oliver Uvman -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: help for sending e-mail using rpc / gwt
Abhi, you could best describe what must be put on every piece of code?

Re: java.lang.NoClassDefFoundError, it probably well known but I cannot found the solution....
I am guessing the class hk/com/carfield/core/Context is performing a restricted operation - like creating a thread or opening a file/socket connection. GAE does not allow you to perform such operations, and when you do - it fails with a stack trace similar to what you have pasted. Disable GAE in your eclipse settings, and completely remove all GAE jar files from your classpath. That should solve the problem. --Sri On 11 May 2010 22:48, Carfield Yim wrote: > HI, I just use the class in another JAR, eclipse show no compilation > error, and GWT compilation is success, why I still get following > error?

Re: Placing xxx.ui.xml files in different packages than counterpart Java files
If you just want to keep your java, css and ui.xml code in different
folders, there's an easier technique. Create two folders parallel to src -
"uibinder" and "css". Or whatever you want to name it. Then add these
folders to the sourcepath in eclipse. These three folders should have the
same package hierarchy, so GWT will be able to find ui.xml and css files
without any problem.
In our project, the above convention helps us to separate ui code from java
code. Keeps the ui folks from stepping over developers toes.

Re: GWT 1.7 to 2.0 upgrading problem: no longer working: GWTCanvas, gwt-diagrams2
It's always good to use the latest version (except for the cases when there are critical bugs), like I did myself last year, jumping from 1.7 to 2.0 Here are some of my discoveries: http://ui-programming.blogspot.com/2009/12/update-your-application-to-gwt-20.html So, generate first a simple GWT 2.0 project using the Eclipse plugin, and then update your module MainApplication.gwt.xml and MainApplication.html according with the recommendations...

Re: Placing xxx.ui.xml files in different packages than counterpart Java files
Hi Sri,
This wouldn't really work for me as we are using maven and maven has
specific standard directory structure. I guess, I could modify the
pom.xml to see those additional directories as source directories as
well, but all that work in maven that would kinda defeat the purpose
for me, i.e., it would now move the "mess" to maven and having to deal
with maven over this is not worth it for us at this point.
I just want to know if it's possible to do this with pure GWT solution or not.
Anyone know?
Thanks,
Yaakov.

Re: Transfer problem from clien side to server side
Hello,
The fact is that normally I had to use gilead to save pojos in a db.
But, before using this, I had to transfer
these pojo to server side. To do this, I use a simple rpc request with
my classes that extend Serializable (and not
IsSerializable because I don't want that my core package has
dependencies with gwt)... But when I transfer some pojo
coming from my core package, there is a problem and I can't transfer
it, no exception but at server side, all reference
of the transfered object are null.. However, if I want to transfer a
class that is present in client package (see my organization
in first post), there is no problem...

gwt webgl smartgwt
Hi I've started to build an application using GWT 2 which will needs an HTML 5 canvas element to display WebGL. I was intending to use smartgwt for the bulk of the UI. Sadly, smartgwt gives layout problems when I add the required by HTML 5 to the main html page of my app. Hopefully this will be fixed in a future version of smartgwt, but does anyone have any ideas for a workaround? For example, could I create a widget which wrapped an iframe and set the URL of the iframe to a page with an html 5 doctype? I could then use this widget to "embed" my webgl viewer. Any suggestions welcome! Thanks! Alan -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Can we check uploaded file Size at client side in GWT by Reading the "header info" of the file
You don't have to wait for the server to download the entire file to give a response, you can get it right away and send back an error immediately; just the cost of a quick round trip to the server. As suggested in many similar posts, gwt-upload is a pretty good solution for file uploads in GWT: http://code.google.com/p/gwtupload/.

Re: GWT 1.7 to 2.0 upgrading problem: no longer working: GWTCanvas, gwt-diagrams2
The indicates that the browser should be running in standards mode, which is required for GWT 2.0's new LayoutPanel type of layout. However just using the original layout panels (FlowPanel, HorizontalPanel, etc) still works the same as ever, in quirks mode. So if a library you want to use doesn't work in standards mode, then just stick with the previous non-LayoutPanels; no need to go back a version. http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html On May 11, 6:28 am, Navigateur wrote: > Is there a way to get these things working in GWT 2.0? > > I've found that gwt-diagrams2 works when deleting from > the html file, but other things don't work then! > > Would anybody recommend me going back to GWT 1.7? > > Many thanks, N > > -- > 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-tool...@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/google-web-toolkit?hl=en. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: help for sending e-mail using rpc / gwt
What have you tried? For example, have you looked at the plentiful example code included with GWT, which includes examples of how to do RPC: http://code.google.com/webtoolkit/examples/ And of course the RPC documentation with example code: http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html The xxxService and xxxServiceAsync are interfaces, which you implement on the server side (xxxService) and call on the client side (xxxServiceAsync), as shown in those examples.

Re: gwt webgl smartgwt
Use emulateIE7 in your html page. I personally had limited luck with this. Another work around is: frames. If your underlying layout is in smartgwt, load your canvas piece as different module html in a frame and vice versa. Both are really bad options, however smartgwt and gwt2 mix and match does not really work well!

Debugger stopped connecting
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I've been trying to integrate the web-socket-js Flash-based WebSocket emulation library (from here: http://github.com/gimite/web-socket-js) into my app. I have it working, but as a side effect my app no longer debugs. I have to compile it and run it in a browser to make it actually do anything. What happens is that I start the debug session, get prompted with the URL to load, load it in Firefox, and just nothing happens. No errors, no Eclipse console messages, no Javascript console messages, nothing. Normally there's a long delay while Eclipse compiles all the Java classes and the app runs. Does anyone have any suggestions of where to look to find out what's going on? My app is rather large, taking several minutes to compile, and I kinda need a working debugger!

Re: gwt webgl smartgwt
Label text appears to ignore the Alignment.CENTER (at least vertically) when placed within a VLayout. I haven't actually noticed anything else, but I didn't want to get a long way into what's going to be a very big project and hit a show stopper, so I'm was looking for a workaround should something critical turn up. So far, I've only checked one version of one browser on one OS. I thought I had seen a mention that smartgwt should be used in "quirks" mode, but I can't find the reference. I'm happy to work with you to solve any issues arising out of using an "html" doctype, that's obviously the best solution. I've done as you asked and placed a small sample on the forum.

Re: Newbie question: How does one write a Unit test for MyClass extends RemoteServiceServlet ???
You can use SyncProxy to test the GWT RPC services See http://www.gdevelop.com/w/blog/2010/01/10/testing-gwt-rpc-services/ for details On May 5, 9:28 pm, Eric wrote: > On May 5, 12:33 am, Mike wrote: > > > Hello > > > Am trying to write tests for my code, and want to ensure that any > > class I write which extends RemoteServiceServlet; > > however, I'm not quite catching on to what I need to do in order to > > get a test to be runnable in that context... > > Have the servlet do all its work in another class, and test that > class, > I guess.

Widget from DOM element
I have had difficulty finding this and figure it must be something stupid I can't find, but how do you create a widget from an element already in the DOM so you can get eventing, or one not in the DOM so you can add it to a panel? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Developer plug-in hangs

Dynamic tab content load in TabLayoutPanel
Hi there! I have a regular TabLayoutPanel and I'm trying to make the content of each tab load dynamically when the user clicks on a particular tab. I tried using a SelectionHandler with no luck, for tab content can't be modified (or that's what I found out so far) and removing/adding a tab is not an elegant option. I also looked up gwt incubator but seems there's no widget in this direction. Any ideas?
