Re: Is it possible to compile java swing application in GWT?

2009-12-09 Thread Olivier Gérardin

I also doubt it will ever exist, one of the reason being that Swing
uses multi-threading and you now that JavaScript has strong
limitations on this.

AjaxSwing looks like a much more realistic way to achieve the same
result through a completely different approach. it doesn't do any code
migration, the Swing app runs unmodified and AjaxSwing acts as a
runtime proxy. I gave it a try and it's very impressive. I don't know
how this would work on a real world Swing app, though.

 Hi all,

 I know this is not possible in plain gwt, but I'm just curious to know
 that is there any add-on tools by using we can translate swing
 application to GWT compatible code?

 We feel there must be something because reason behind developing GWT
 application in java is that already there are so many swing based
 application which are now want to migrate web based.

 I've already tried AjaxSwing which is completely different framework.

 Thanks,
 Vikas

The element you're trying to wrap is a child of an element that's the
root element of a widget. A widget is supposed to control its
subtree, so wrapping a widget's child element in another widget is
prohibited, as the parent widget would be aware of it.

DomEvent.fireNativeEvent(Document.get().createChangeEvent(),

or you could use the ValueChange event instead, which you can fire

Giving GWT another test drive

2009-12-09 Thread HB

Hey,
In the past I developed a GWT application for our client.
The application was built upon Spring Framework and Hibernate ORM.
While I love and adore GWT, I stopped using it for:
1. Building the interface in the code was a killer thing for me.
2. Difficulties marshelling Hibernate objects back to the client,
workarounds are so tedious and time consuming
GWT 2 looks refreshing to me, if Declarative User Interfaces
delivers what it says I will be definitely re-dive into GWT.
But what about integrating GWT with Spring/Hibernate? should I expect
the same awful issues or things are better now?
Thanks GWT, you rocks.

Really, you don't want your hibernate lazy loading instances in the

But, if your only problem is coding and using a dedicated ui model, I

I am using gwt-dispatch and creating command-dedicated models for my

TabLayoutPanel css

I can't believe that

 - gwt 2.0 is out,
 - we have the old themes instead of injectable client bundles,
 - TabLayoutPanel does not have a default css in the standard theme.

I know GWT is not eye candy but all about software engineering, but
would it have been too much to add a simple implementation for us to
be able to use the components out of the box?

Is it on the pipeline for 2.0.0.1 or are you serious about this? Just
wondering.

MVP, GIN, UiBinder

Hi,

as many other GWT developers I really like the above mentioned
approaches.

I am having a little bit of pain when it comes down to embedding views
into views. UiBinder and GIN don't play well together, I am struggling
with ugly locator pattern usages to create my sub/ embedded views. My
code is now full of //WORKAROUND task tags, hoping to get it solved
somehow someday.

But that is the point: at which direction should I look? MVP tells me
to have views injected into my presenter, really nice. UiBinder on the
other hand needs the views, would create them properly, but then they
would not be available to GIN (compile-time vs. runtime).

If my feeling is right, we would need some way to hook up into the
UIBinder, providing a GIN based MVP resolver, quite similar to the
variable resolvers people use in JSF to get hands on Spring beans from
JSF. But as far I can see, UiBinder does not provide such extension
point.

Any thoughts here?

brgds,

Papick G. Taboada

Re: how large of your GWT compiled code? My one is 850K

2009-12-09 Thread Luis Fernando Planella Gonzalez

Sorry for taking so long to answer, but I haven't seen your post
before.
We haven't yet done any larger performance test, but it is very
acceptable.
Yesterday, in a first no-brainer attempt of GWT.runAsync(), I've
managed to get a 650K initial download and then a separate file per
module (for now, modules varies from few K to 180K).
I'll still try to reduce both the initial download and the modules.
It does takes more time to compile now. That's an issue to me as I
can't use the built-in server: we use EJB, so there's an external
server. Whenever anything changes in RPC (params, methods, even
classes) we need to recompile :-/
I still didn't implement gzip compression, but hope things can get
much better...
Ah, about IE6: as our app is targeted to late 2010, we won't support
IE6 \o/

 Hi,

 Our app,  50 -55 % done so far, for one browser is nearly 1.6 MB

 Luis, Question for you:
 As you said your app is 2.1 MB of obfuscated, how is the preformance
 and does it has any issue?

 Question to all:
 What is the max size that of GWT one module that a browser can handle
 without any issue, specially IE 6, in our case :-(         ?

 Thanks,

GWT using domain models /services from external module (jar) ?

2009-12-09 Thread ashika umanga

Greetings,

We have been using our reusable user-management module which was
written using Spring/Hibernate(using Doman-Model Pattern).We have used
that module in several project integrating with Wicket,JSP and ZK
frameworks. Now I am going to develop an application using GWT.I am
completely new to GWT and I noticed that the domain objects should go
inside xxx..client package. But I want to use our reusable
module (jar) and the domain model is in completely different package.
How can I use my domain-model object from this external library in
GWT? How about service interfaces? Do I have to write proxies for them
too?

thanks in advance

HtmlUnit seemly can not run JavaScript(GWT) on GoogleCodeSearch pages

2009-12-09 Thread Phan The Dai

Hi everyone,
I am trying using HtmlUnit for parsing and checking a
GoogleCodeSearch's Url, for example
Url = http://google.com/codesearch/p?hl=en#BDMVBjMQ9dM/developer/
technicalArticles/jini/javaspaces/HelloWorld.zip|0GBefwhg-XQ/
HelloWorld.javaq=HelloWorld%20lang:java

But I could not get the content as that is displaying on the Web.
In the data (page.asXml) that HtmlUnit returned, I could not find
where content of file HelloWorld.java is.

This is my code:
final WebClient webClient = new WebClient();
webClient.setJavaScriptEnabled(true);
final HtmlPage page = webClient.getPage(Url);
webClient.waitForBackgroundJavaScriptStartingBefore(1)
System.out.println(page.asXml);

I think HtmlUnit can not run some JavaScripts on the GoogleCodeSearch
Webpages which use GWT for create scripts.
It is right? Please show me some solution for this situation!
Thanks much!

Regards,
Dai Phan

GWT Hosted Mode

I have a strange issue.  I have no errors and no runtime errors occur
when loading but nothing but the html shows up in hosted mode.  A test
project works just fine but, in order to use my project I have to
compile it.  I am using App Engine 1.2.8 and GWT 1.7.1.  If you could
let me know of any additional information that would be helpful I will

MouseOver with previous MouseDown - problem in IE

2009-12-09 Thread mh

Hi,
I've created a Composite, consisting of a Panel and a FlexTable, along
with another Composite, consisting of a Panel and an Image, which was
supposed to be put in the FlexTable.

I wanted to create a simple dragging mechanism for the selection - so,
to each cell composite have mouse handlers.

The thing works fine in all the browsers, except for the IE.

When the mouse button is down, the proper cell's MouseDownHandler is
triggered. When the mouse button is still down, and the mouse is being
moved over another cell, the MouseOverHandler is triggered, however,
for the cell that had had the MouseDown.

Is it the issue of the GWT, or I am doing something wrong?

Regards,
mh

Nesting layouts with gwt 2.0

Hi,

I am having trouble with nesting layouts.

My nested layout is:

DockLayoutPanel (main window)
   TabLayoutPanel (tabs for modules on the main window)
   Simple Hello World Tab (nothing special, fast forward pls)
   SomeTreeBasedPanel (ok, here trouble begins)
   DockLayoutPanel
   west: tree
   center: scrollpanel


In my app I need to select a node on the tree and get some content
displayed on the center area of the dock panel.

The nested DockPanel in the scrollpanel is not rendering properly and
I can't figure it out why.

I have uploaded the compiled app to:

http://static.pgt.de/nestedlayouts/NestedLayouts.html

The zipfile with the project is here:

http://static.pgt.de/nestedlayouts/NestedLayouts.zip

A screenshot of the app is here:

Hope someone can help me out here,

Re: Strange scroll behaviour of ScrollPanel

2009-12-09 Thread romant

Ok I got it work, in case anyone is interested - to simulate the
common FAQ page behaviour the simplest approach seems to be setting
the scroll position of a ScrollPanel like this:

int pos = panelToShow.getAbsoluteTop() - scrollPanel.getAbsoluteTop();
scrollPanel.setScrollPosition(pos);

panelToShow is one of many panels placed in a ScrollPanel.





On 29 lis, 16:53, romant roman.te...@gmail.com wrote:
 Hi,
 I tried to implement a widget which would realize the commonly used
 FAQ page approach (which means questions as links situated at the top
 and answers below, when a link is clicked the panel scrolls at the
 correct position to show the corresponding answer).

 I expected that using ScollPanel and its ensureVisible() method will
 do the job. It does actually but in a very strange way. I would expect
 that when one of the top links is clicked thescrollpanelwill scroll
 so that the corresponding answer will be aligned right at the top of
 the visiblescrollpanel'sarea. But it is not and I have no idea why.
 It seems that the position of the element which is desired to be
 visible is rather random.

Re: GWT Chat applications

Slow on what end?

Sure, pushing from server would lead to instant message delivery, but
I don't think it scales very well.
Do you know how may connections you can keep open?
You could change the polling rate depending on the load status of the
server, just a thought.

 Any thoughts here?

How about injecting your child views (or Providers) into your view

RequestBuilder

2009-12-09 Thread charlie

I have a php page
http://the-charlie.com/artwork/index.php?artist=Kanye+Westalbum=Graduation,
that when I hit it directly gives me an image URL.

I have this code in my app

RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
http://the-charlie.com/artwork/index.php?artist=Kanye+Westalbum=Graduation;
);

try {
builder.sendRequest(, new RequestCallback() {

@Override
public void onResponseReceived(Request request,
Response response) {


Window.alert(response.getText() );
Window.alert(response.getHeadersAsString());
Window.alert(response.getStatusText() );

Window.alert(Integer.toString(response.getStatusCode()));
}

@Override
public void onError(Request request, Throwable
exception) {


}
});
} catch (RequestException e) {

e.printStackTrace();
}

}

Which is always returning null , with a status code of 200.

If my app runs on port 8080, is it a problem hitting a page on port 80 ( the
php page ) ?

Why would this constantly be returning blank ?

Thanks!
Charlie

2009-12-09 Thread Rajeev Dayal

Hi,

When you were installing the plugin, did you have the option Contact All
Update Sites During Install to Find Required Software checked?

Our plugin has some dependencies on WST, and some installations of Eclipse
do not have them by default. However, the Galileo update site (which is
included in the list of default update sites) has these dependencies, and if
you have the option that I mentioned above selected when you install the
plugin, it will automatically grab them.

Let me know if this doesn't work for you.

Re: MVP, GIN, UiBinder

Well, that is what I am sort of doing. And it turns out to be a kind
of service location.

There are some workarounds, and they are nothing more than just that:
a workaround.

I am letting GIN build all of my presenters, and then I let them bind
the UIs.
Not nice, but that is the way with the fewest dependency lookup calls
for me atm.

Re: RequestBuilder

Hi,

different ports are indeed an issue, see SOP 
http://en.wikipedia.org/wiki/Same_origin_policy...

I tried your code here and got a status code 0.

For test purposes, dump your response data into your war folder and
change the url to the new location.

If it works, it is not your code, it most probably is SOP.

brgds,

Papick

ps: I use GWT.log(Got status code  + response.getStatusCode(), null)
to log instead of Window.alert.

Re: PoupPanel and scrolling with the scroll wheel

2009-12-09 Thread jdw

Scroll bars do work when a modal dialog or modal popup is visible.  I
verified this with the DialogBox example.  I don't believe that
modal behavior should mean you can't scroll.  Using setGlassEnabled
( true ) is not an option as we are using GWT 1.7

Does anyone know a way to get the scroll wheel to work when you have a
modal dialog visible?

 That's because of the modal behavior of the DialogBox/PopupPanel, or
 more exactly how it is implemented in GWT. You'd rather use a non-

 (and not only wheel scroll doesn't work, but you cannot use scrollbars
 either)

Re: GWT Chat applications

2009-12-09 Thread Jim

hi, I've implemented a gwt Chat

the link 
http://code.google.com/p/google-web-toolkit-incubator/wiki/ServerPushFAQ
helps me.

From client, i do an rpc call
-- server-side, i'm waiting for event (using a timer) for the
client :
-- if i got an event for the client, i return to the client, and i do
again the rpc call.
-- if no events after 40 sec, i return to the client and says to the
client No events!, and i do again the rpc call.

i18n with GWT 2.0

2009-12-09 Thread ericv

Was wondering if anyone had already taken a look at GWT
internationalization in 2.0, and more specifically, if there were
changes to the location of property files (which have to reside in the
same folder as the referring class in GWT 1.7.1 for the generated i18n
commands).

More generally, is there a way to group i18n data files in a resource
folder, to keep them away from the source code tree?

No changes in GWT 2.0 AFAIK, but you can put your properties file in
another folder if you want, provided you build the whole package
folder hierarchy their too; what matters is not the location on disk,
it's the classpath, so you can have (and it's been the case for a
loong time):
 - src
   - com
  - my
 - app
- client
   MyMessages.java
 - resources
   - com
  - my

Re: PoupPanel and scrolling with the scroll wheel



On Dec 9, 5:22 pm, jdw jwootto...@gmail.com wrote:
 Scroll bars do work when a modal dialog or modal popup is visible.  I
 verified this with the DialogBox example.  I don't believe that
 modal behavior should mean you can't scroll.  Using setGlassEnabled
 ( true ) is not an option as we are using GWT 1.7

Can't you switch to GWT 2.0 now that it's officially released? you
shouldn't even have to modify a single line of code (except the call
to setGlassEnabled and the associated CSS), just recompile and profit.

 Does anyone know a way to get the scroll wheel to work when you have a
 modal dialog visible?

Before we switched to GWT 2.0, we were using the GlassPanel from the
GWT-Incubator, show the glass panel and then show the dialog
(eventually, override the dialog's show() and hide() methods to
automatically show/hide the associated glass panel).

 Our plugin has some dependencies on WST, and some installations of Eclipse

 you have the option that I mentioned above selected when you install the

Re: Extending Splitter related widgets

Hi Nathan,

That is exactly the thing. GWT is much more than widgets and the
provided ones should be the building blocks to extend. That is the
message that comes from the team behind GWT. The problem I see is that
some widgets are not designed to be easily extended and therefore they
are not good building blocks. This leads to the integration of
heavyweight third-party widget libraries (even for simple things) or,
in the other hand, to the development of custom widgets to avoid this
overhead. I expected that, with the new versions, this situation would
change integrating most of the widgets of the incubator refined to fit
the widget framework over which to build the new widgets.

Cheers,
Alberto

Creating and maintaining custom widgets is discouraged

Really? I had the opposite impression. I understand why it might be
discouraged, but from everything I've heard the GWTers tend to assume
that they are only providing basic building blocks in the widgets
package. I could be wrong (and I would like to be; maintaining custom
widgets _is_ a pain), so if you have any references indicating
otherwise, let me know!

On Dec 7, 2:34 pm, lemaiol lema...@gmail.com wrote:

I have recently started having a look at the GWT 2.0 RC2 version and
found me once again frustrated trying to extend the SplitLayoutPanel.
In version 1.4 we needed to do the same with the splitter panels and
we thought that some of the reasons not to build more easy to extend
Splitter panels (had to copy over a lot of code) had to do with the
implementation substitution performed by the compiler.
In this case, I miss setting the splitter position programmatically
(or associated widget size) and setting the maximum splitter size
(minimum is already possible to be set) in the SplitLayoutPanel. With
the current implementation (a really simple one) the changes are not
complicated. The only problem is, that as the widget is implemented,
it is not possible to extend it properly.

Could somebody give some input on this? Why the SplitLayoutPanel is a
basic part of the new layout system but does not allow extension
easily? Creating and maintaining custom widgets is discouraged and a
pain but the actual widgets are sometimes not designed even for
trivial extension.

Feedback really appreciated,
Alberto

GWT 2.0.0 JPEG errors with JAI and JAI-IMAGEIO

2009-12-09 Thread Thad

I am using Sun's Java Advanced Imaging (JAI) and Java Advanced Imaging-
Image I/O (JAI-IMAGEIO) on the server side of my application for
reading and processing TIFF's and other images which are then scaled,
converted to PNG, and sent to the browser.

Today I downloaded and installed GWT 2.0.0.  In attempting to run the
sample Showcase, I receive javax.imageio.IIOException's on the JPG
images, like jimmy.jpg.  This happens only if the $JAVA_HOME I'm using
has JAI and JAI-IMAGEIO installed.  Without JAI, the JPGs open fine.
(Note:  Yesterday with GWT 2.0.0 RC2 I was able to modify the JPGs by
converting them to/from PNG but that trick is not working today).

The stack trace strikes me as screwy, since the images start with the
proper 0xff 0xd8 0xff 0xe0:

No, though you obviously have to add the resources dir to your

Upgradeing to 2.0, web.xml file problem

2009-12-09 Thread darkflame

Upgrading to 2.0, and I started getting problems with my web.xml file.
Specifically its complaining of some wrong set up with my log class in
use (which is ; http://code.google.com/p/gwt-log/downloads/list).

The complaint was;

[WARN] Server class

found in the web app, but was found on the system classpath
   [WARN] Adding classpath entry 'file:/D:/TomsProjects/Google%20GWT/

Now I did try adding this to my web.xml file;


?xml version=1.0 encoding=UTF-8?

...and got the same error.

I also tried with;

...same error.

Any ideas?
It was working fine in 1.7.
I'm using eclipse and have run the update. (and changed the project to
2.0).

I have recently started having a look at the GWT 2.0 RC2 version

SplitLayoutPanel.
In version 1.4 we needed to do the same with the splitter panels
and
we thought that some of the reasons not to build more easy to
extend
Splitter panels (had to copy over a lot of code) had to do with the
implementation substitution performed by the compiler.
In this case, I miss setting the splitter position programmatically
(or associated widget size) and setting the maximum splitter size
(minimum is already possible to be set) in the SplitLayoutPanel.
With
the current implementation (a really simple one) the changes are
not
complicated. The only problem is, that as the widget is
implemented,
it is not possible to extend it properly.

Could somebody give some input on this? Why the SplitLayoutPanel is
a
basic part of the new layout system but does not allow extension
easily? Creating and maintaining custom widgets is discouraged and
a
pain but the actual widgets are sometimes not designed even for
trivial extension.

Feedback really appreciated,

Deprecated SerializableException

2009-12-09 Thread rjcarr

I'm attempting to upgrade to GWT 2.0 and everything is working well
enough except I am getting this warning in the compile step:

Referencing deprecated class
'com.google.gwt.user.client.rpc.SerializableException'

And the file it mentions is a gwt derived file with the suffix:
_TypeSerializer.java

The warning always happens on service classes (i.e., RemoteService),
but doesn't seem to happen on *all* service classes.

I have not defined SerializableException explicitly, but my method
signatures do throw Exception.

Any idea why this is happening and what I can do to make it go away?

Thanks!

 The warning always happens on service classes (i.e., RemoteService),

 I have not defined SerializableException explicitly, but my method
 signatures do throw Exception.

 Any idea why this is happening and what I can do to make it go away?

GWT 2.0 Eclipse Breakpoint Not Working

2009-12-09 Thread Nick

I just updated my Eclipse plugin from GWT 1.7 to GWT 2.0. I got my
application to run in a separate browser, however, it does not ask me
to install a plugin, nor does it stop on breakpoints.

Can anyone help me convert my 1.7 Eclipse GWT/App Engine project to
GWT 2.0?

What I've done:
-Updated my Eclipse Plugin
-Changed my GWT version to 2.0
-Changed my App Engine version to 1.2.8
-Deleted by current launch configurations
-I launch by Right Click--Debug As--Web Application (the one with
the 'G' on it).
-I copy the URL give in the Development Mode tab in Eclipse and paste
that into Chrome (I've tried FF and IE 7 as well).
-My App appears and seems to work properly, but no question to install
a plugin nor does it pay attention to breakpoints.

If I can avoid creating a new project and copying it into that, I'd
prefer it.

I appreciate any help.

-Nick

GWT 2.0 crash on IE7 - post-UiBinder setCellHeight with VerticalPanel

2009-12-09 Thread Stuart

Environment: MS Windows, Eclipse 3.5 with GWT 2.0 plugin.
Testing on: FF (Win/Mac), Chrome (Win/Mac), IE7(Win)

Basic widget hierarchy:
- EntryPoint loads a DockLayoutPanel via UiBinder.
- in the center of the dock, loads a VerticalPanel
- the VerticalPanel has 3 custom composite widgets in my app's
namespace, each of which have to appear exclusively in the dock's
center pane when certain events are fired

Post-binding logic:
- after the EntryPoint creates and binds the UI, we need to turn off
2 of the 3 custom widgets.
- this is accomplished by the following code:

// turn off widget 1
vPanel.setCellHeight(customWidget1, 0px);
customWidget1.setVisible(false);

// turn off widget 2
vPanel.setCellHeight(customWidget2, 0px);
customWidget2.setVisible(false);

// turn on widget 3
vPanel.setCellHeight(customWidget3, 100%);
customWidget1.setVisible(true);

Error:

In IE7, the first reload in DevMode crashes with:

com.google.gwt.core.client.JavaScriptException: (Error): Invalid
argument.
 number: -2147024809
 description: Invalid argument.
at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript

(Element.java)
at com.google.gwt.user.client.ui.CellPanel.setCellHeight
(CellPanel.java:104)
   

The next line in the stack trace is the first attempt at:
vPanel.setCellHeight(customWidget1, 0px);

FF (Win/Mac), Chrome (Win/Mac) all do this properly.
The IE7 dev plugin tells me gracefully that the server is
disconnected.
My eclipse console reports the above stack trace.

The end result is I have no application in IE.

(Now, someone is going to say: Why are you using VerticalPanels? Long
story, but I have not found a suitable replacement in the new UI
panels to handle sizing without becoming a PhD in CSS quirks.)

As I trace through the code, I am looking at this path:

- We programmatically set the cell height of the widget to 0px
(allowed by CSS) from its parent vPanel
- CellPanel.setCellHeight gets the widgetTd as an Element
- Element.setPropertyString sets the property string of 'height' to
'0px'
- this method is JSNI that sets this[name] = value in the
JavaScriptObject

I lose the code for a little while as it delegates through to
ModuleSpaceOOPHM(ModuleSpace).onLoad(TreeLogger).

When we try to exit the onModuleLoad via line 374 of
com.google.gwt.dev.shell.ModuleSpace
exit.invoke(null, true);

... we step into oblivion.

The user agent for this terrible show-stopping surprise for my
application is:
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR
2.0.50727)

Help!

GWT 2.0 dead in IE7?

2009-12-09 Thread Stuart

@bruce, @jwg, @rjrjr

(and any other gwt'ers listening)

I just posted about a fairly severe show-stopper for my application
(that is, the app doesn't even finish onModuleLoad() in IE7 (see
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/952cdae8b5efa1d3)

I thought it was likely due to my code. So I built a dead simple
EntryPoint using the UiBinder wizard with a few touch ups:

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.HTMLPanel;
import com.google.gwt.user.client.ui.RootLayoutPanel;
import com.google.gwt.user.client.ui.Widget;

public class UiBinderTestForIE implements EntryPoint {

private static UiBinderTestForIEBinder uiBinder = GWT.create
(UiBinderTestForIEBinder.class);
interface UiBinderTestForIEBinder extends UiBinderWidget,
UiBinderTestForIE {}

@UiField Button button;
@UiField HTMLPanel htmlPanel;

public void onModuleLoad() {

Widget w = uiBinder.createAndBindUi(this);
RootLayoutPanel root = RootLayoutPanel.get();
root.add(w);
}

}

And here is the ui.xml

!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
ui:style
.important {
font-weight: bold;
}
/ui:style
g:HTMLPanel ui:field=htmlPanel
Hello,
g:Button styleName={style.important} ui:field=buttonUser/
g:Button
/g:HTMLPanel
/ui:UiBinder

When I launch this in Chrome / FF, I get what I expect. When launched
in IE7, there is nothing on the page. Yet, the console reports that
the module has been loaded.

At first I thought it was a problem with the developer plugin in IE,
so I compiled it and put it up on my App Engine sandbox:
http://uibindertestforie.latest.emcode-dev.appspot.com and tested from
two different machines. Works in FF/Chrome on both machines. Nothing
in IE7 on either machine.

What's the deal?

Again, it could be my code. But, really? GWT 2.0 is dead in IE7? I
can't actually believe it, so someone please tell me what I am doing
wrong.

GWT 2.0 Using External Resources

2009-12-09 Thread fmk11

Hi,

I'm following the new Dev Guide for UiBinder, but I'm encountering a
problem with the @Resource annotation. Specifically, I'm getting
compile errors on @Resource .. anyone knows what needs to be
imported? It does not seems to be defined in ClientBundle.

I'm inheriting inherits name=com.google.gwt.resources.Resources /
 in my .gwt.xml but that does not seems to help.


Thanks in advance,

PS: This is the relevant piece of code:

public interface Resources extends ClientBundle {

@Resource(/stylesheets/colors.css)
Style colors();

public interface colors extends CssResource {
String  brickRedBg();
String  brickRedFg();
String  lightOrgangeBg();
String  lightOrgangeFg();
String  offWhiteBg();
String  offWhiteFg();
String  steelBlueBg();
String  steelBlueFg();
String  glaciarBlueBg();
String  glaciarBlueFg();
String  grayBg();
String  grayFg();
String  petrolBg();
String  petrolFg();
String  limeBg();
String  limeFg();
}
}

Re: GWT 2.0 Eclipse Breakpoint Not Working

I had this problem too.  It only asked for the Firefox plugin after I
deleted my projects compiled javascript under the war directory.

Also, after the FireFox plugin did get installed, I then restarted
everything, and Firefox froze and asked me if I wanted to terminate
the current script.  I said yes, and breakpoints worked, but code
updating didn't.  Restarted again, and said continue when Firefox
asked if I wanted to terminate the script.  Everything is working
great now!  :-)

Window.open to include gwt.codesvr parameter

When Window.open(url, _blank, ); is called, it opens a new window
without the gwt.codesvr parameter.

Is there an option to tell it to include the gwt.codesvr parameter if
running in debug mode?

It is possible to code around it with something like this:
  String devMode = Window.Location.getParameter(gwt.codesvr);
  if (devMode != null) {
url += gwt.codesvr= + devMode;
  }

however, I would rather not have to do that.

help debugging gwt apps with database

2009-12-09 Thread rjcarr

I'm an old school gwt user, and as such, so is my gwt project.  I
think it was initially created using GWT 1.3.  I have since updated
the SDK along the way and made the necessary changes (and just
completed the work for 2.0).

However, since my gwt project existed long before gwt had eclipse plug-
ins (or even ant scripts), I've never taken advantage of the gwt
debugging tools available to eclipse.

My project uses database connectivity so whenever I wanted to run
bytecode instead of javascript I needed to use the 'noserver' flag and
set up my own tomcat.

What I'd really like to do is use all the eclipse debugging features
for my project.  I've read the docs and they explain how to set up the
noserver but not how to debug (which is essentially what I already
have).

So, a couple questions:

 1) Can you use the gwt eclipse plug-in debugging tools if your server
runs a database?  If so, how?
 2) If debugging doesn't work with a database then is my only option
to set up eclipse to work with tomcat?

Problem during upgrading to GWT 2.0

2009-12-09 Thread Simal

Hi all,

I'm sure this is related to build/run configurations but couldn't
figure it out after a long day..

I'm upgrading from GWT 1.7 to 2.0 and when I try to open up my
application in a browser, I get the
GWT module '' needs to be (re)compiled, please run a compile or
use the Compile/Browse button in hosted mode message.
I think this message is somehow from GWT 1.7 (since we no longer have
a Compile/Browse button in the hosted mode in 2.0).
I'm using Eclipse. I changed my build path and run configurations to
use the GWT 2.0 jar files. My war/WEB-INF/lib directory contains the
GWT 2.0 gwt-servlet.jar as well. I don't quite understand why it's
referring to a message from an earlier GWT version.

Can anyone think of a point I might be missing? Any other
configuration I should be looking into? Any specific ordering of the
jar files in the build path or run configurations? Any caching that
might be happening?

Thanks in advance,
Simal

Re: GWT 2.0 Eclipse Breakpoint Not Working

I had this problem too. It only asked for the Firefox plugin after I
deleted my projects compiled javascript under the war directory.

Also, after the FireFox plugin did get installed, I then restarted
everything, and Firefox froze and asked me if I wanted to terminate
the current script. I said yes, and breakpoints worked, but code
updating didn't. Restarted again, and said continue when Firefox
asked if I wanted to terminate the script. Everything is working
great now! :-)

I just updated my Eclipse plugin from GWT 1.7 to GWT 2.0. I got my
application to run in a separate browser, however, it does not ask me
to install a plugin, nor does it stop on breakpoints.

Can anyone help me convert my 1.7 Eclipse GWT/App Engine project to
GWT 2.0?

What I've done:
-Updated my Eclipse Plugin
-Changed my GWT version to 2.0
-Changed my App Engine version to 1.2.8
-Deleted by current launch configurations
-I launch by Right Click--Debug As--Web Application (the one with
the 'G' on it).
-I copy the URL give in the Development Mode tab in Eclipse and paste
that into Chrome (I've tried FF and IE 7 as well).
-My App appears and seems to work properly, but no question to install
a plugin nor does it pay attention to breakpoints.

If I can avoid creating a new project and copying it into that, I'd
prefer it.

I appreciate any help.

Re: GWT 2.0 Using External Resources

 Hi,

 I'm following the new Dev Guide for UiBinder, but I'm encountering a
 problem with the @Resource annotation. Specifically, I'm getting
 compile errors on @Resource .. anyone knows what needs to be
 imported? It does not seems to be defined in ClientBundle.

 I'm inheriting inherits name=com.google.gwt.resources.Resources /
  in my .gwt.xml but that does not seems to help.


 Thanks in advance,

 PS: This is the relevant piece of code:

 public interface Resources extends ClientBundle {

@Resource(/stylesheets/colors.css)
Style colors();

public interface colors extends CssResource {
String  brickRedBg();
String  brickRedFg();
String  lightOrgangeBg();
String  lightOrgangeFg();

String  offWhiteFg();
String  steelBlueBg();
String  steelBlueFg();
String  glaciarBlueBg();
String  glaciarBlueFg();
String  grayBg();
String  grayFg();
String  petrolBg();
String  petrolFg();
String  limeBg();
String  limeFg();
}

Re: Problem during upgrading to GWT 2.0

2009-12-09 Thread Simal

OK.. I guess I found the reason.

The directory that gets automatically generated under war, the one
that has the module name, had to be deleted. I think the contents of
that folder were not getting updated after I compiled with GWT 2.0 and
it was kind of reading from cache.

Hope this helps someone..

 Hi all,

 I'm sure this is related to build/run configurations but couldn't
 figure it out after a long day..

 I'm upgrading from GWT 1.7 to 2.0 and when I try to open up my
 application in a browser, I get the
 GWT module '' needs to be (re)compiled, please run a compile or
 use the Compile/Browse button in hosted mode message.
 I think this message is somehow from GWT 1.7 (since we no longer have
 a Compile/Browse button in the hosted mode in 2.0).
 I'm using Eclipse. I changed my build path and run configurations to
 use the GWT 2.0 jar files. My war/WEB-INF/lib directory contains the
 GWT 2.0 gwt-servlet.jar as well. I don't quite understand why it's
 referring to a message from an earlier GWT version.

 Can anyone think of a point I might be missing? Any other
 configuration I should be looking into? Any specific ordering of the
 jar files in the build path or run configurations? Any caching that
 might be happening?

 Thanks in advance,
 Simal
