I tried to use a gwt fileupload widget to send a csv file to the

it by doing : (where request is the httpservletrequest and bw is the
bufferedwriter)
BufferedReader r = request.getReader();
while((thisread= r.readLine())!=null){
bw.write(thisread);

bw.close();
}

--WebKitFormBoundaryN8Z6DOy7DqEWTwtLContent-Disposition: form-
data; name=uploadFormElement; filename=first.csvContent-Type:
application/octet-streamBank
which results in the file created not the same as the file upload.
I might be wrong in my analysis. can someone advice me?

Re: Question about using user defined serializable types in GWT
Writing client code, you have to use classes supported by GWT JRE Emulation:
http://code.google.com/intl/es/webtoolkit/doc/1.6/RefJreEmulation.html. So
you have to use only these classes in serializable objects that are used in
both the client and server sides. Unfortunately java.lang.Thread is not
supported so you can not use it.

Why is GWT even bothering with the Thread field when it has been

To accommodate the new value all three libraries have a new version available for download. Links and additional details for the three projects can be found below. Before I talk about what's new for each of these projects though I'd like to take a moment to reach out and thank everyone who reported a bug, submitted a feature request or contributed a patch. It's really amazing how the efforts of individuals can be compounded for the benefit of all the developers in the community using these libraries and ultimately all the users of their apps.

While I have your attention, I'd like to express my interest in hearing more about how you are using these libraries in your web applications, what features you appreciate the most and which ones you think could use some improvement. In particular, I'm interested in how you might be using these libraries in team settings or in more complex development scenarios. It could be that you or one of your colleagues has built a library or higher level API on top of one of gwt-dnd, gwt-log or gwt-voices. Or that you collaborate with a group of developers on an enterprise application which has specific needs and requirements which aren't typically found in smaller application. Please send me an email.

Re: GWT URL Parameters
You cant actualy change the url parameters like you can the history, because changing them would refresh the page. google.com#?blah=blah would be a history token that just pretends to be a normal parameter. (and Window.Location.getParameter wouldnt work for it). This can be changed without a page refresh Any change before a #, however (such as google.com?blah=blah) would cause a page refresh, and thus cant be done with a continuously running app. This cause's much announce in combination with the fact severs cant access #, as it makes it very hard to give your users url's which both always link to the same data, and work for clients without javascript. (such as google bots) On Jul 16, 5:46 pm, KevMo kevinps...@gmail.com wrote: Thanks Max, I did find that post earlier, however since there is a built in way of getting URL parameters I thought there would also be a built in way of setting them.

Re: New problem of blurHandler and setFocus on GWT 1.6
Problem solved (but not clean).
I still have not found the true answer, but I wanted a way to show you
a trick to avoid it. It is due to the propagation of the Click-Event
and to solve it I have add event.stopPropagation() in the first line
of the function onClick, and it works even though not very clean.
public void onClick(ClickEvent event) {
event.stopPropagation();
edit();
}

Nono
Hi,
Could you try to addBlurEvent after setting focus to true ?

Hi,
When I set setFocus on a object it is focussed and immediatly after,
an onBlur event is send. I did not have this problem on 1.5 with
focus listener. You can see the code below. solidify is call
immediatly after we have time to see that the area of text has been
selected. Maybe the onClick event haven't been destroyed ?
Thank for your help,
Nono
public void edit()
{
this.clear();
areaOfText = new SuggestBox(Text.suggestions);
areaOfText.setText(text.content);
areaOfText.addStyleDependentName(Integer.toString(level));
/* PROBLEM HERE */
areaOfText.getTextBox().addBlurHandler(new BlurHandler(){
public void onBlur(BlurEvent event) {
solidify(areaOfText.getText());
}
});
this.add(areaOfText);
areaOfText.setFocus(true);
/* END PROBLEM */
}
public void solidify(String newContent)

{
this.text = text.createNewText(newContent);
this.info = this.info.createNewInfo(text, text.id);

Re: App engine data types
Thanks man! Saved me a few hours for sure.
Can't believe nobody needed this yet - should be a part of GWT.
It's not that I want to send a Text or a Blob via RPC - but I
definitelly want my data classes to be usable at the client side
(translatable).
The Text I'm going to put in a String in a JDO load callback function,
so that it can be RPC'ed to client and used in a standard string-ish
way, and similarly in the other direction.
The separation of the jars into client and server was a bit confusing
to me, however I've added both into my project's classpath and then
included the gwt.xml, and it seems to work.
Btw. the gwt.xml (same contente) is in both of these jars - is that a
bug or am I doing something wrong?
thanks again,
J.

I actually started using the persisteddataclasses and sending them

JDO started putting fields on my classes that were instances of Object

going to be a performance hit with sending a lot ofdataover the
channel. So, I am thinking that doing a lite DTO just for transport
would possibly be my best option.
I will check out Ray Cromwells posts, mainly I guess what I am looking
for at this point is a good reference for using the super-source tag
and how to make custom wrappers for non GWT classes (in the same

Any pointers in that direction would be great.

It could be two things: - a bad path to the bundle (IE is known to have some bugs re. resolving relative paths, though it shouldn't affect ImageBundles; but maybe if you're playing with the paths when deploying your app) - ImageBundles use an ActiveX (filter: AlphaImageLoader), so it might really be a security thing. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT project runs slow in Hosted mode
We are having the same issue upgrading from 1.5 to 1.7. For our application, we have GWTX in addition to the GWT. For our project, we have 4 GWT modules that are in development. For hosted browser with the -noserver option, our launch time in 1.5 was ~90 seconds and is now over 10 minutes in GWT 1.7. Some initial investigation indicates that removing our public resources gives a modest improvement but nowhere close to GWT 1.5 times.

How to center root panel?
Hi!
I have trouble getting my root panel centered in the host page.
I´ve looked at the posts here and tried things like
CSS
body {
margin: 0 auto 0 auto;
padding: 0;
width: 792px;
}
But my page is still not centered vertically, only horizontally.
Posting my onModuleLoad() below
public void onModuleLoad() {
HandlerManager eventBus = new HandlerManager(null);
TimeServiceAsync timeService = GWT.create(TimeService.class);
AppData appData = new AppData();
TimeWidget timeWidget = new TimeWidget();
TimePresenter timePresenter = new TimePresenter(timeWidget,
appData,
timeService, eventBus);
TabPanel basePanel = new TabPanel();
basePanel.setWidth(500px);
basePanel.setAnimationEnabled(true);
basePanel.add(timeWidget,Current time);
basePanel.add(new WelcomeWidget(),About);
basePanel.add(new LinkWidget(), Some GWT links);
basePanel.add(new ContactWidget(),Contact);
basePanel.selectTab(0);
RootPanel.get(simpleContainer).add(basePanel);

gwt 1.6 and oophm, how to?

Re: Command Pattern, MVP, EventBus
I really think it's a purely philosophical decision - I can see how it would work fine with EventBus, I'm just choosing not to, basically. For me the line in the sand is that events are about information, commands are about action. Your mileage may vary :) David On Jul 18, 7:22 am, Kwhit kwhitting...@gmail.com wrote: On Jul 15, 9:36 pm, David Peterson da...@randombits.org wrote: - Thinking further, I think it's better to separate the EventBus from - the Command system somewhat. The reason being that generally, events - are used to update on changes that have already happened, or are about - to happen. They don't trigger the actual event itself. Yes I've been thinking about that. Any user action that interacts with the server: sign in, create account, update address, etc., has an asynchronous response. I find myself tempted to wrap the service request in and make it synchronous but that would be morally wrong and lead into all kinds of difficulties in the details. So I've gone the other route... My proof of concept implementation treats a click on the 'sign in' button as an event which it fires and forgets to the event bug. Maybe this goes too far in the other direction - time will tell.

Re: App engine data types
Juraj,
Thanks for using the lib :) I'm glad it's useful.
The way I came to develop that is basically to take apart another
lib/module I was using (I think it was gwt-math). So, I basically
just followed what I deduced from reading that module. I also tracked
down a book that had some mention of the Xyz_CustomFieldSerializer
idea, but really didn't give sufficient details to use it. I found
that the gwt.xml was in both the server and client jars in modules
I've imported, so I simply did the same thing, if there's a more
efficient way to get around that, I'd love to hear about it, but it
seems to work for my purposes :)
The client jar has some source files that aren't compiled by javac,
but are evaluated by the gwt compiler. The server jar has classes
that are compiled by the javac compiler. Basically the reason for
that is 'cause I had to emulate the
com.google.appengine.api.datastore.* classes by putting them in the
folder com/resmarksystems/emul/com/google/appengine/api/datastore/
(which gets ignored by the javac compiler) but I also needed classes
that got compiled to byte code in the
com/google/appengine/api/datastore folder, and those classes can't go
in the client code ('cause they're in the wrong package) but the ones
in the com/resmarksystems/emul/* folder can go in the client code.
So, they get separated accordingly.
Again, I'm sure there's gotta be a better way to do this, but it seems
that modules made by google follow this pattern and I couldn't find
very good documentation on how to do it. So, sorry for the confusion.
please let me know if you run into issues with the library
thanks!

Thanks man! Saved me a few hours for sure.
Can't believe nobody needed this yet - should be a part of GWT.
It's not that I want to send a Text or a Blob via RPC - but I
definitelly want my data classes to be usable at the client side
(translatable).
The Text I'm going to put in a String in a JDO load callback function,
so that it can be RPC'ed to client and used in a standard string-ish
way, and similarly in the other direction.
The separation of the jars into client and server was a bit confusing
to me, however I've added both into my project's classpath and then
included the gwt.xml, and it seems to work.
Btw. the gwt.xml (same contente) is in both of these jars - is that a
bug or am I doing something wrong?
thanks again,

I actually started using the persisteddataclasses and sending them

JDO started putting fields on my classes that were instances of Object
[] (which don't serialize all that well). That, and I know there is
going to be a performance hit with sending a lot ofdataover the
channel. So, I am thinking that doing a lite DTO just for transport
would possibly be my best option.
I will check out Ray Cromwells posts, mainly I guess what I am looking
for at this point is a good reference for using the super-source tag
and how to make custom wrappers for non GWT classes (in the same

Hi ... I have a project that demonstrates an RPC failure that I don't know how to fix.I use eclipse 3.4, gwt 1.6.4 and google-plugin. I have an RPC that is working fine in web mode (deployed under tomcat) but fails in host mode. The failure message is (when the application run in host mode): SEVERE: [1247902594529000] javax.servlet.ServletContext log: Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method '...' threw an unexpected exception: java.lang.NoClassDefFoundError: Could not initialize class com.application.core.HibernateUtil Can someone take a look at this and give some suggestions/reasons?? I don't know what to do from here. Thanks for the help ! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT Commerce - A rewrite of OSCommerce using GWT and PHP
Hi, I've opened a project called GWT Commerce at http://code.google.com/p/gwt-commerce/, my goal is to provide a rewrite of OSCommerce using GWT. I've made a lot of progress and was recently contacted by a Software Engineer who wanted to help, I've agreed and he is going to work on Administrative use cases. I think I am at the point that I would like some real community involvement. I am looking for help with: Documentation (isn't everyone), testing, some design, coding and best practice advice. Code (written so far) is checked in, I still have to get an example database checked in so that other people can run it. Also plan on placing a working demo on a domain I own, hopefully all of this by the end of the month. Please contact me if interested. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Creating Stand Alone Composite??
I'm trying to create a stand alone composite widget and am totally clueless as to how. I want to create a widget that will be able to be used in any of my multiple GWT modules. Every example on the web that I can find defines the composite in the same module that displays the composite. I need to see an example of two modules, one defining the composite and one that consumes the composite. If anyone has an example or can point to a web article showing how, I'd GREATLY appreciate it.

Re: Creating Stand Alone Composite??
If you have the composite, create a new .gwt.xml file in this module without any entry-point tag and include this new .gwt.xml file in the other module. For instance: - you have your composite in the name space 'com.module1.client' and the content of com/module1/Module1.gwt.xml is: module inherits name='com.google.gwt.user.User' / entry-point class=com.module1.client.Module1/ /module - you want to use your composite in com.application.client whose com/application/Application.gwt.xml is module inherits name='com.google.gwt.user.User' / entry-point class=com.module1.client.Module1/ /module - create a new file in module1: com/module1/Include.gwt.xml module inherits name='com.google.gwt.user.User' / /module - Modify your application's descriptor module inherits name='com.google.gwt.user.User' / inherits name='com/application/Application'/ entry-point class=com.module1.client.Module1/ /module You have to be sure that all the source classes are in your classpath. BTW: You can pack set of composites and widgets taking care that the module's descriptor has no any entry-point tag and the .jar file contains the java source files.

[gwt-contrib] Re: GWTCanvas status?
Appreciate your replies, I now have a much better sense of where GWT vector graphics is heading. With my use of GWTCanvas, the fact that there was a per-pixel memory cost with the canvas tag (that does not exist with VML) forced me to do some extra work to shrink-wrap the canvas around each rendered curve. So, I can imagine how having everything sort of work like VML (element based rather than pixel based) could be a big consistency plus. I also found Ray's argument that many have tried to emulate canvas with VML and failed convincing. On the other hand: o The use of Flash would create a new proprietary dependency that does not exist with GWTCanvas at present. o Though my vector graphics needs were limited (I only required a canvas subset) I was able to do everything I wanted to using GWTCanvas (though working around the IE bugs was a pain). o Relative to other browsers, with the feature subset I used, IE's vector graphics rendering isn't nearly as slow as its HTML rendering. So, once I figured out I needed to minimize stroke count, I was happy with the IE rendering performance of GWTCanvas. From the perspective of a black-box user of GWTCanvas, except for the IE bugs (which I was able to work around) it met my application's needs well. Without it GChart would still be stuck in the visual getto of HTML-only rendering. So I hope any improved system will preserve GWTCanvas' many good features, such as being packaged as a Widget, and having a reasonably low cost per widget (which made it possible for me to give each curve it's own GWTCanvas, and update them independently). My totally biased operational definition of if any new vector graphics library is 'good': when I implement GChartCanvasLite using the new library, my live demo and tests will 'just work', and run as fast or faster than with the GWTCanvas based implementation. On Jul 17, 7:33 am, Joel Webber j...@google.com wrote: Ray's basically right about this -- you can't simulate canvas on vml (extant attempts to do so with limited success notwithstanding). When GWTCanvas was originally designed, SVG performance on some browsers was absolutely atrocious, while Canvas and VML were basically acceptable. So Jaime and I attempted to design an API that would use Canvas and VML for a rendering layer, while trying to nudge the developer towards a use pattern that would work well in practice. Since then, the situation has changed quite a lot. SVG performance on Gecko, WebKit, and Opera has finally gotten up to speed, making it possible (or at least a *lot* easier) to build a sensible scene-graph API that uses just VML and SVG. I strongly believe this will end up being a better API, because the rendering back-ends will be (more or less) equally capable and similarly constructed. Dan Rice (cc'd) has started working on this approach, but it may be a little while before it sees the light of day. In the meantime, if you have patches for any of the issues you listed in GWTCanvas, don't hesitate to let us know. Cheers, joel. On Fri, Jul 17, 2009 at 12:04 AM, Ray Cromwell cromwell...@gmail.comwrote: The only realistic way to truly emulate canvas on IE is to use Flash. VML just doesn't cut it. Even after lots of community effort on excanvas.js, it still falls short of even the old Canvas that Safari first exported, and that doesn't even take into account that performance is pretty bad too. Silverlight could be a deferred binding option as well, but Flash has 95% penetration and would work in a majority of cases. You could still fallback to VML in some of those intranet settings that don't allow plugins, but as you say, you'd have to bifurifcate the Canvas API into what's supportable by VML and what's supportable by everything else, and code your draw paths to deal with them separately. Even with Flash, there's some stuff like fetching or setting pixel data that would be quite slow, in that regard, I think image processing ops should be encoded declaratively in a scenegraph, much like Java2D/JAI Renderable, and shipped over to Flash for execution rather than trying to bring them into the browser's JS engine. -Ray On Thu, Jul 16, 2009 at 8:36 PM, John Gunther johncurtisgunt...@yahoo.com wrote: There are a number of GWTCanvas bug reports that are still categorized as New, some several months old, some submitted by me. http://code.google.com/p/google-web-toolkit-incubator/issues/list?can...
