Re: RPC Deployment issue

2009-05-12 Thread Magius


If you are using Eclipse, you can setup 'projectName/war/WEB-INF/
classes' as the default output folder
and the class files are compiled and placed in this folder
automatically.
'ant' is the best way but with Eclipse is fastest to test it


On May 11, 9:30 pm, Sumit Chandel sumitchan...@google.com wrote:
 Hi Harry,
 You will need to build the starter project in order to generate the
 server-side GreetingServiceImpl.class files. You can do this by downloading
 the Apache Ant build tool and running ant from the command-line while in
 the starter project directory.

 The ant build command will read the build.xml file located in the project
 directory and proceed to build your GWT project while cross-compiling the
 starter GWT code to .js and .html files, compiling the server-side classes
 to .class files, and copying these resources to the appropriate directories
 in the war output folder.

 For more on the Ant build tool:http://ant.apache.org/

Re: GWT 1.6 - How do I change the default war directory name


Hi,

 I will need to do migrate to 1.6 sometime, and I just don't like the
 war-WEB-INF directory imposition and mixing source-control files with
 generated files.

I wrote a tutorial explaining how to use maven and the m2eclipse
plugin to overcome this exact problem. You might want to take a look
at it and give some feedback. Here's the url:

Dear GWT community,

I am considering using GWT 1.6 in a project, but have one major
concern: GWT 1.6 no longer places the public files (like the host page
or the module XML) in the public sub directory of the root package
but inside a war/module directory.

As all my projects already exist and e.g. use WebContent or Web
etc. as root for the directory containing all the static content, it
would be nice to reuse the existing structure.

My question is therefore: Is there a way to change the default
directory name war to something else. I would be surprised if not,
but I haven't found any info in the GWT documentation pages. It would
be great if someone could help me.

Thanks in advance,

  I think that this is a bad move.  This will be an infinite loop

[ERROR] Not enough arguments (2) passed to external.gwtOnLoad(), expected (3); error

2009-05-12 Thread darkflame


I'm getting a;

[ERROR] Not enough arguments (2) passed to external.gwtOnLoad(),
expected (3); your hosted mode bootstrap
file may be out of date; if you are using -noserver try recompiling
and redeploying your app

Error in the development shell when I run my project.
This error has only just appeared despite working on my project for
weeks without even touching the run or compiling configurations.
It seems to have appeared after introducing another Frame element,
sometimes setting the url seems to trigger it but I cant find any
logic to this error appearing.

This may be tied to me still using com.google.gwt.dev.GWTShell to
compile, despite the deprecated warning I get in eclipse. (I'm using
the default 1.5 directory layout still, changing to
'com.google.gwt.dev.HostedMode' would mean having to change that
right?)

I think the  ProjectName.nocache.js wont increase much at all, but the
other bits will.

I'm still using 1.5, which loads the bulk of it in *.cache.html files.
(with different ones used for different browsers)

Either way, generaly speaking size is liked to how many different
types of widgets and libs you are using.

Can we use Servlet Listeners directly in GWT1.6? As i can see web.xml.

I am trying to do so by counting the number of users connected. But
the sessionCreated method is never executed.

Any guesses?

Does this mean in hosted mode we cannot use listeners?

Re: how ho handle handlers

2009-05-12 Thread romant


That's something what interests me as well.

 Hello everybody,

 i have a different question, but it's also related to the handling of
 handlers.

 Recently, i read the article of Fred Sauer about best practices in
 widget building.
 (http://googlewebtoolkit.blogspot.com/2009/05/widget-best-practices-
 widget-building.html)
 At the end of the article ('clean up after yourself'), he says the
 registration of DOM event listeners should occur in the onLoad method
 and not in the constructor when extending Widget directly.The onUnload
 method should remove the registration. As he is referring to CheckBox
 as Example, this relates to DOM.setEventListener.

 Now here's my question:
 - Should I do the same when extending Composite and when I'm only
 using addDomHandler() ? For example, if i have a composite that uses
 some handlers (i.e. MouseIn / MouseOut). Should i setup the handlers
 in onLoad and keep a reference to the HandlerRegistrations and remove
 them in onUnload ?

 Thanks,

 Holger

Re: Official word on Safari 4 public beta support

2009-05-12 Thread Churky


I think my problem stems from upgrading an existing gwt application
from 1.5x to 1.6x.

I have started my development of the gwt application under 1.5x and in
the middle of development bump into some issues with gears
integration. And I found that 1.6.4 and gears 1.2.1 is integrated into
a single jar. So I decided to make an upgrade. After I install gwt-
gears 1.2.1, and make the necessary changes in my build path with the
new jars. I was no longer able to start the application. And got a
weird message saying I must have Safari 3 install. I Google this error
and found that there was many mentioning that Safari 4 was not
supported. Some of these posts where as recent was last month.

Because I need the application to run ASAP, I decided to uninstall
Safari 4 and put Safari 3 back. But the problem was still there. So I
no longer think it is a Safari problem, more likely on the upgrade,
and might have some code conflicts. Since then. I have created my
application from scratch starting with gwt-gears 1.2.1, and GWT 1.6.4,
and have reinstalled Safari 4. The problem no longer there, and have
no had much problem getting the application to run correctly.

Hope my notes help.

 Hi Churk,
 It would be great if you could let us know what issues you experienced when
 trying to run your GWT application on Safari 4. As far as I know, there
 shouldn't be any major changes that we need to make in GWT to support Safari
 4 because of backwards-compatibility. Meanwhile, we may want to make some
 updates to take advantage of some of the new features in Safari 4, but
 that's another issue.

 Hopefully you can let us know what you experienced when trying to use your
 application on Safari 4. It should work, but we would like to be on top of
 any improbably but potential edge cases that may come up.

gwt 1.6.4 and Gears 1.2.1 Documentation?

2009-05-12 Thread Churky


I have been searching everywhere for a tutorial on how to create a
project using gwt 1.6.4 with gears 1.2.1. I have found an old
documentation for gwt 1.5.x, But that document no longer valid for
many of the steps in 1.6.x, There is no more AppCreator, or the tag -
eclipse. So I was wondering when the documentation would be update
which shows the uses of gears 1.2.1 integrated? Such that when you
import the project into eclipse, you'll have all the necessary jars
imported and able to compile.

The gwt eclipse plugin can not create a new project and compile gears
code when the hosted browser is launch. Not even if you include the
gwt-gears.jar into the build path.

GWT 1.6 + Spring Security issue

2009-05-12 Thread tim.clymer


I've been seeing a strange issue when attempting to use GWT with
Spring Security as described here:
http://code.google.com/p/gwt-incubator-lib/

I can deploy the application as a war and run it just fine in Tomcat,
however when I try to run it in hosted mode with jetty I get the
following error:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Unable to locate Spring NamespaceHandler for
XML schema namespace [http://www.springframework.org/schema/security]
Offending resource: ServletContext resource [/WEB-INF/aop-
applicationContext.xml]

I've posted this to the Spring forums and they mention it's a
classpath issue, that there may be more than one instance of the
Spring Security jars on my classpath.  I've double-checked my jars and
this doesn't seem to be an issue (especially since I package them with
my app and it works fine).  I'm wondering if somehow jetty or GWT is
using a class that might be interfering with the resolution of the
namespace.  Prior to incorporating security in my app it was running
fine in hosted mode, even with other Spring beans, so this makes me
think it's related to Spring Security (and not just Spring itself)
somehow.

Any ideas?

Ajax request handler

Does GWT have a mechanism to intercept/handle all ajax requests?  I'm
looking for something like prototypejs ajax responders http://

in gwt's javadocs.  In our case, we want to show a 'loading' message

PHP programmer - is GWT for me?

2009-05-12 Thread pappfer


Hi!

I'm a web programmer. I mainly code in PHP with MySQL and also
familiar with XHTML and CSS. I also have some Java and basic
JavaScript knowledge.

But I never used Ajax before. I was thinking that it might not worth
to study how Ajax works cause it'd take lots of time and I thought
using a Javascript library would probably be a better choice. I read a
lot about them and I found Dojotoolkit to be the best for me.
But then I read about GWT that it makes super-fast Javascript which
would be great for me and I would also get more into Java. So it
seemed perfect for me. I read the documentation and saw how to make a
simple client application.

But then as a web programmer the most important thing for me was to
make use of client-server communication to put some Ajax power into my
PHP applications. But I found this part quite difficult.
I use Eclipse PDT and the GWT's Eclipse plugin. I realized that when
creating a new web application and I'm copying my PHP files onto that
application folder I can't use PDT's tool for PHP cause I can only see
the project if I'm using Java perspective.

Overall, my goal is to put some Ajax power in my PHP applications. For
example I have a website about mobile phones and I store all phones
and all the data in a MySQL database. I want them to be searchable
without reloading the page. Or I want to click on a Next phone
button to see the next phone in the database without reloading the
page or a Compare phones button and want to compare two selected
phones without reloading the page.

My questions are:
- Is GWT for me? Or I'd rather use Dojotoolkit or another Javascript
library?
- What's the best way to set up (organize) a PHP project and connect
it with GWT? (I mean folder structure and everything)
- What's the best to use for client-server communication: JSON, XML or
something else? (if I want to do stuffs like at the above examples)

Hosted mode

2009-05-12 Thread Kelo


I created a web app with google plugin on Eclipse Ganymede 3.4, then I
made an entry on Debug Configurations... - Web application. Running
on Hosted Mode, it didn´t stop on my breakpoints. After that I tried
including gwt-user.jar on Classpath - User Entries but I coudn't make
it works.

Re: Serialization


 From a java perspective, Serialization implies a contract that GWT  
(or more specifically Javascript) cannot fully uphold, so originally  
the developers created IsSerializable which implies the subset of the  
Serialization contract that could be upheld.

As GWT progressed, it turned out that this thinking was a bit too  
restrictive, and required contamination of data objects that would not  
necessarily be needed, so the regular Serializable interface became  
allowed as a GWT serialization marker as well.

On the GWT side of things, both interfaces are treated equally. If you  
have objects that are ONLY serialized for GWT-RPC, and they don't  
necessarily uphold all of the other assumptions of a fully  
Serializable Java object, then it is probably more appropriate to use  
the IsSerializable interface so you don't run afoul in the Java world.

Re: IncompatibleClassChangeError when launching hosted mode (GWT 1.6 M2)

2009-05-12 Thread Josué


Hi,

I have the same problem here but the suggestion did not worked to me.
Here is my scenario:

I have a pom.xml (maven) in which most (but not all) project´s
dependencies are  placed. When i put the following, the problem
appears:
...
dependency
groupIdorg.codehaus.mojo/groupId
artifactIdselenium-maven-plugin/artifactId
version1.0-beta-3/version
scopetest/scope
/dependency
...
In the moment the only jar that is not in the pom.xml is gwt-user.jar.
There is no available maven repository (at least the ones showed in
the search inside eclipse). I did as suggested here and my Order and
Export is in this way:

gwt-user.jar
projectName/src
projectName/test
JRE System Library [jre6]
JUnit 4
Maven Dependencies

And all other jars is inside Maven Dependencies. Any suggestions would
be very appreciated.

Abraços,

Josué.

Running 3rd party javascript after GWT FINISH running

2009-05-12 Thread Ben


I am working on a project which mainly uses GWT for the application
but uses 3rd party javascript as well. I am running into a problem: I
need to use 3rd party javascript to manipulate the page DOM. Since the
page is mainly coded in GWT, then I have to make sure the 3rd party
javascript executes AFTER GWT module finishes running and adding all
elements to the DOM otherwise the 3rd part javascript gets an
incomplete page. For example:

head
script type=text/javascript language=javascript
src=3rdparty.js/script
script type=text/javascript language=javascript src=gwt/
gwt.nocache.js/script
/head

I want to make sure 3rdparty.js executes after gwt.nocache.js finishes
running.

I have a solution in which I manually expose a Callback function in
GWT onModuleLoad() method. But is there anyway to solve this problem
without adding extra codes to my GWT codes?


Thanks,

Re: RPC Call and onSuccess get File.


CAREFUL! If you do your processing in an RPC remoteServiceServlet,  
then in onSuccess() you window.open using a particular URL to fetch  
the generated file your users (well non-IE users anyway) will never  
see that file.

Popup blockers will prevent the opening of a window that is not a  
direct result of a user action. So, you would need to open the window  
as a result of a user click (the action that fires off the RPC for  
instance), hold a reference to the window, and then change (set) the  
URL in the onSuccess() method.

 I think that this is a bad move.  This will be an infinite loop
 because Javascript is single-threaded.  In fact, I don't think that
 your asynchronous rpc handler ever is getting exercised, because  
 this
 loop will tie up the Javascript thread.  If you really want to do
 something like this, you need to do it periodically on a Timer.

Check the 'problems' view in eclipse for any warnings of an out of date

Alternatively, delete the jar from you WEB-INF/lib and the use the problems

It looks like you are using ORM.  There are a couple of places where GWT

GWT + APIs and no internet connectivity

2009-05-12 Thread Thomas


Hello,

i am prototyping a couple of applications and I am amazed how easy it
is to get things up and running.

The Visualization API with GWT is my main interest and have done the
first tests already. But I have a blocking issue, because the
application cannot access the internet where it will run.

Is there a way to run visualization applications without internet
connectivity?

The idea is to resolve all needed URIs internally on a local server if
needed. But I haven't seen any documentation about that, I don't even
know if it is possible,

Bye

GWT Server push

2009-05-12 Thread zimzalabim


Hi everyone!

I am totally new to GWT and have created a simple client/server app
that does nothing but sends a string from client to server.

Now I would like to expand it so the server can send messages to all
clients. How can this be done?

I think the technique one might use for this purpose is called 'server
push'. Can anyone provide a link or some code to demonstrate this in
its very simplest form?

All answers are truly appreciated!

Thanks!

Internal Compiler Error

Hi all,

I'm developing a simple testing application with (GWT 1.6.4) and Ext

Server push example

2009-05-12 Thread zimzalabim


Hi all! Please bare with me if my questions is newbie'ish or if it has
been answered before, tough I couldn't find an exact answer.

Ok, I am totally new to GWT and what I have seen so far is impressive.
I have created a very simple GWT client/server application, where the
user types his/her name and sends it to the server, then the server
replies with a greeting.

Now, I would like to extend this example to make the server
'broadcast' a message to all clients. I believe this mechanism is
called 'server push'. My question is if someone can help me implement
this simple requirements or guide me to some resources that shows how
it could be done.

Any help would be greatly appreciated!

Thanks!

Newbie question about war file deployment for Tomcat

2009-05-12 Thread bartomas


Hi,
I've generated a war file using GWT. I have placed it in the webapps
folder of the tomcat directory (which is installed locally).
How do I now start the application from a client browser?
I have tried http://localhost:8080/ApplicationName
but it doesnt work. I guess I'm missing something basic.
Thanks very much for any help.

Android application generation with GWT

Hi,

Would it be possible, in a while, to generate an Android application
from a GWT code (instead of generating a web application) ?
It would be great...

Re: Application out of Date error

Miguel,
Thanks for the suggestion, there aren't any errors on the server side.
Here's my ...impl method code:

public ListCountry getAllCountries() {
/*PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(Country.class);
try {
  ListCountry results = (ListCountry) query.execute();
  return results;
} finally {
  query.closeAll();
  pm.close();
}*/

Country c = new Country (Jamaica, -0.1f, 0.1f);
ArrayList Country list = new ArrayListCountry(1);
list.add(c);
return list;
  }

The Country class consists of simple String and float fields, so it's
definitely serializable (I hope).

2009/5/12 Miguel Méndez mmen...@google.com

 It looks like you are using ORM.  There are a couple of places where GWT
 serialization and ORM don't play nice together.  An exception should be
 getting logged on the server if that is the case.

Re: Server push example

2009-05-12 Thread Célio


We have implemented a push service using the long polling technique.
It works basically like this:

- the client makes a request to a service;
- in the server side, the service blocks while waiting for an event to
happen for a specified amount of time (30 seconds, for instance);
- either when (1) the desired event occurs or (2) the time is over,
the service stops blocking and finishes execution, responding to the
client;
- the client handles the response and...
- ... repeats the request to the service

Of course, that technique is not efficient for a relatively high
number of clients since the server will hold a thread for each
blocking request.  If that's a problem for you, take a look at Jetty's
implementation of Continuations.

Regards,

Célio

Re: Application out of Date error

2009-05-12 Thread Isaac Truett


I believe the server is trying to persist the enhanced version of
the serializable class, which makes it appear as if the class has
changed, triggering the out-of-date exception. I saw something similar
before switching to separate persistable data objects and DTOs.

Re: Newbie question about war file deployment for Tomcat


In your ApplicationName.gwt.xml, there is an attribute rename like

http://localhost:8080/showcase/ApplicationName.html.

Re: Eclipse Plugin Compile Button Stack Overflow

2009-05-12 Thread louatia...@gmail.com

settings are below

-Dhttp.proxyHost=myProxy.mydomain

-Dhttps.proxyHost=myProxy.mydomain

with these setting it just can't reach appengine.google.com

in the second case when I add

-Dhttp.proxyUser=me

-Dhttps.proxyHost=me_crypted

it returns an 407 exceptionnn

this is really blocking

Hi Denis,
If the command line workaround works for you, you can proceed to deploy
your
GWT application to Google App Engine by invoking the uploader utility
with
the command below:

..\appengine-java-sdk\bin\appcfg.cmd update war

The GWT compiler will generate output in a standard war structure, which
you
can then directly deploy to Google App Engine to host your application.
If
you're using the AppEngine SDK that came with the Eclipse plugin, you
can
find it in the directory below:

\eclipse\plugins\com.google.appengine.eclipse.sdkbundle_1.2.0.v200904062334\appengine-java-sdk-1.2.0\bin

You can read more about deploying your application to Google App Engine
at
the link below:

Hope that helps,

Using GWT compiler is automated for App Engine deployment.

Because that's what deployment is? Maybe I'm not understanding
your

just
for
debugging. For deployment, you compile the Java code into
actual
Javascript.

BTW what does it change to use GWT trunk ?

From what I could tell, not much. But there could be more
unknown
bugs
whatnot. However, it should compile - according to the Google
developers,
they have other internal teams working against trunk.

I'm using it and I still have the issue... (and I can't deploy
and
oophm doesn't have a compile button yet, fortunately i can

So what's the issue? What do you mean you can't deploy? You

you

Re: Invalid version number 1.5 passed to external.gwtOnLoad(), expected 1.6

2009-05-12 Thread Alex Moffat


I've just had exactly the same problem. Turned out that the hosted
mode browser had the previous version of the hosted.html file cached.
I pulled it up in the browser by entering the url directly and it
showed the 1.5 version even though the app server was receiving a
request for the file. Shift refresh in the browser retrieved the
correct version and things are now working fine.

 Thomas, thank you for the reply.

 Now, that you said, I checked it out and I'm using SDK 5 in all

 I were using before changind the command line arguments (added -
 noserver and changed the -startupUrl), it couldn't be the problem.

 It's looks like some initialilzation problem, once I haven't calling
 through hosted.html. If you take a look at this html, you will see
 that the correct  initialization is there (external.gwtOnLoad(window,

  It looks like you compiled you app with a 1.5 SDK (HostedMode expected

  and the hosted mode must use the same SDK version.

1.6.4 on FreeBSD 7.1 segfaults

2009-05-12 Thread KaffeineComa


Trying to compile GWT 1.6.4 under FreeBSD is causing the JVM to
segfault.  Our  build server is based on FreeBSD, so we just trying to
get the stuff to compile; not running hosted mode or anything that I
would expect to need native libs.  I do see that Maven is including
gwt-dev-1.6.4-linux.jar in the classpath; I don't know if this is
related or not.  Thanks for your attention.

 I must admit that I've not personally researched it.  I think that it has
 been discussed on the appengine user group however.  You may also want to
 search this group.
 The problem, as I understand it, is that enhancement adds fields to the
 runtime type.  But, GWT-RPC works off of the static (pre-enhancement) view
 of the type which is why you get the errors.  I'm not sure what the best
 work around is.  I do know Ray Cromwell has done some looking into it.


 Thanks, Miguel.

 @Pavel I think a good starting point is here:

 http://timepedia.blogspot.com/2009/04/google-appengine-and-gwt-now-marriage.html

 A key bit is this:
  @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable =
 false)

 that's it. As soon as I comment out the @PersistenceCapable it works!

 Now I know there are issues w/ GWT and enhanced classes, but exactly how
 am I supposed to persist data w/o having that annotation?

 2009/5/12 Miguel Méndez mmen...@google.com

 What if you try to have it not be persistable (comment out the
 persistence annotations, rebuild, and return a dummy one that was not
 instantiated by the ORM code)?  I wonder if this is the ORM and GWT-RPC
 incompatibility.

RPC problem after deploying on server

Re: RPC problem after deploying on server


For GWT-database application, you can find an example in
http://www.gwtorm.com/mail/Mail.html. The source code is also
available there.Usually this kind of issue is due to serializable or

Re: css for flextable's columns

I owe my thanks to Thomas and Salvador for the table-layout: fixed

  Your suggestion regarding overflow has led to a solution. After

  the innermost table cell - to the Label - and it works! So happy.

  In respect to fixing FlexTable cells' width. I am so far stuck with
  Having each single cell a Label/Panel within with a fixed width. The
  FlexTable itself has a fixed width defined, but what happens is, if
  some of the cells contain no information they get squeezed by the
  other ones, regardless of the {width:xxx} set on them.

Hello,

have already spent some hours trying to set column width in flextable

that is achievable (target browser IE 6). I tried with width attribute

Doing that now through putting label with predefined fixed width, but
that is so ugly and wasteful.

   You should just have to ensure your CSS for the table has table-
   layout: fixed (hint: it'll also speed up the rendering of the table,
   explicitly telling the browser to not account for the cells' content
   width)
   I don't think I had a problem with empty cells, but I'm not even sure
   I ever had to deal with empty cells...

And one more thing. I have a HorizontalPanel in one of the flextable
cells with 3 labels inside, is there a way to apply overflow:hidden
on the last widget? Right now it is being wrapped to the next line,
although overflow: hidden is set.

   Hmm, it probably depends on the size (intrinsic or explicit) of the
   HorizontalPanel, if you set the width of the HorizontalPanel with an
   absolute unit (pixels, for example), you should IMO put
   overflow:hidden on the flextable's cell, *not* the HorizontalPanel's
   last cell.

Re: Second try: app works on Linux, but not on Windows (1.6.4 hosted mode)

2009-05-12 Thread mlgm


Scott,

thanks for the answer, I was giving up my hope!

I did the debugging you asked for and from what I found, I was able to
find the problem and a workaround myself :-). I'm not sure though if
it should work as it was before. At least with Firefox on Linux it
did, but I'm no browser and JavaScript expert.

What happened is this: I'm trying to build an application, where the
GWT module should react on an outside parameter. As a possibility for
doing this, I had found the following solution on the Internet. First,
I created a little JavaScript inside the host page (i.e. a host
servlet) with a variable for the parameter:

   script language=javascript
  var event=aa00aa00aa00aa00aa01;
   /script

Then this variable is read from inside the GWT module by using a small
native JavaScript method:

public native String getEventRID()/*-{
return $wnd.event;
}-*/;

The problem now seems to be, that I called my variable event (as in
performance). If I change the variable name to something else, it
works. As I said, I'm more of a Java expert and have nearly no
JavaScript knowledge and don't know if I'm not allowed to create a
variable named event, at least in Internet Explorer. BTW, I tested
it with IE6 and IE7, but not IE8.

In case you might want to analyze this further, here are the debugging
values:

In IDispatchImpl.callMethod()

   cl = com.google.gwt.dev.shell.compilingclassloa...@ea5140
   jthis = null
   params = [VT_BSTR{aa00aa00aa00aa00aa01}]
   method = static boolean com.google.gwt.user.client.DOM.previewEvent
(com.google.gwt.user.client.Event)

In SwtOleGlue.convertVariantsToObjects()

   i = 0

Thanks again and GWT rocks!

Best wishes

Michael

Use GWT to send the file to your server for validation. Downloading and 
activating a Javascript XML validation tool (assuming it exists) is just 
unnecessarily cruel to your users. Do such validation on your server, 
and pass the results back to the client.

Chrome Safari Compatibility

2009-05-12 Thread Blessed Geek


Is it true that GWT is not qualified to work on Chrome and Safari?
(Having previously been on quality engineering, the term qualified I
use carries a certain industrial sense.)

I created a site with tabs, where each tab is associated with a panel.
And the panels respectively display documents from picasa, sites and
docs. All of which contained in the root panel.

I set the absolute distance of root panel from top of browser page at
90px. No problem when viewing using hosted browser, IE or Firefox.

However, with Safari  Chrome, the supposedly static distance set at
90px varies up and down depending on the type of document being
displayed due to the tab selected.

From that behaviour, I am guessing that GWT is not preferred to be
deployed on Chrome or Safari, is that true?

Is there a list of browsers qualified to work with GWT?

Irreverent/irrelevant comments:
Also, it would be intriguing that Google would not make GWT work with
Chrome (vice versa). Isn't it like as much intriguing that Google
would not make Adsense work with Sites.

Rather, it is more accurate to say that I set the absolute distance of

I have hidden the database-communication part of the code but the

That would probably explain it.  $wnd.event is a special field I think, and
if you're manually setting it to a String where someone else expects it to
be an Event Object, that could definite explain the cast problem.

Re: IncompatibleClassChangeError when launching hosted mode (GWT 1.6 M2)


Hi Josué,

I recommend you learn more about dependecy management with maven as
the problem your facing is easily solvable once you've understood how
it works.

Anyway, the solution to your problem is excluding the conflicting
jetty dependency in your pom. Replace your selenium import with the
following:

dependency
groupIdorg.codehaus.mojo/groupId
artifactIdselenium-maven-plugin/artifactId
version1.0-beta-3/version
scopetest/scope
exclusions
exclusion
groupIdjetty/groupId
artifactIdorg.mortbay.jetty/artifactId
/exclusion
/exclusions
/dependency

Hope that helps,

Salvador

Re: GWT + APIs and no internet connectivity


Hi,

The Google Visualization APIs create images or flash files on google's
servers so there's no way to use them without internet access. There
are however other equivalent visualization apis that you can install
on your local servers to get similar functionality.

Cheers,

Salvador

 Hello,

 i am prototyping a couple of applications and I am amazed how easy it
 is to get things up and running.

 The Visualization API with GWT is my main interest and have done the
 first tests already. But I have a blocking issue, because the
 application cannot access the internet where it will run.

 Is there a way to run visualization applications without internet
 connectivity?

 The idea is to resolve all needed URIs internally on a local server if
 needed. But I haven't seen any documentation about that, I don't even
 know if it is possible,

 Hi everyone!

 I am totally new to GWT and have created a simple client/server app
 that does nothing but sends a string from client to server.

 Now I would like to expand it so the server can send messages to all
 clients. How can this be done?

 I think the technique one might use for this purpose is called 'server
 push'. Can anyone provide a link or some code to demonstrate this in
 its very simplest form?

 All answers are truly appreciated!

TabPanel border -- how do I make it invisible?

2009-05-12 Thread Rob Tanner


I'm attempting to use my first TabPanel.  The TabPanel is displayed
with a two or 3 pixel border in a light blue.  While I want the tab
bar itself is fine, I want the border on the panel (DeckPanel??) to be
zero pixels.  How do I get rid of it?

Re: Chrome Safari Compatibility

I've never had any problem getting GWT to work in Chrome, but it is true to
say that Chrome (and to a lesser extent Safari) are the most fussy
especially when it comes to heights and widths (and one or two known issues
like the size of Courier New).
Some working (or rather, not-working) code would be really useful in trying
to work out what might fix it.

 Rather, it is more accurate to say that I set the absolute distance of
 the panels 90px from the top of the root panel - to make room for page
 logo and header text.

Re: Chrome Safari Compatibility

It should be noted however that this doesn't mean that GWT is not
preferred to be deployed on Chrome or Safari just that there will
probably be some layout differences.

There are almost always workarounds for layout differences, it's just
a matter of making choices and compromises.

Re: TabPanel border -- how do I make it invisible?


hi,

Have a look at the developer's guide:
http://code.google.com/webtoolkit/doc/1.6/DevGuideUserInterface.html#DevGuideStyleSheets

And the to the javadoc for the tabpanel and tabBar:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/TabPanel.html
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/TabBar.html

And then for a good example of tab panel styling take a look at the
showcase:
http://gwt.google.com/samples/Showcase/Showcase.html#CwTabPanel

Also, firebug is a great tool for css on-the-fly modification so be
sure to get it.

Hope that helps,

Salvador

Listbox onChange event

2009-05-12 Thread huy


The onChange event is working correctly.  The problem is when I hold
down the up/down key and an onChange event occur for every item
selected.  I just want to fire the event for the last item selected
when the key is let go.  I tried adding a keyboard listener and
removing the changelistener when key is down and adding it back when
key is up.  The problem with that is I'm missing the last event.  Any
help is appreciated, thanks.

Re: Chrome Safari Compatibility

2009-05-12 Thread Vitali Lovich

Safari is supported AFAIK.  Chrome would be too since it is Webkit like
Safari, although I don't know how much QA effort goes towards it - probably
minimal for three reasons:
 1) it uses the same engine as Safari
 2) it has minimal browser share
 3) it's Google's browser that they want as standards compliant as possible,
meaning few/no browser-specific workarounds are necessary ( since there's
only 1 version with a 2nd on the way, it's not much of an issue).

The combination of 1  2 make spending time on heavy QA of Chrome explicitly
(outside of maybe some unofficial smoke tests) probably unlikely.  However,
I have no idea what the process is internally, so my guess could be way off.

Re: Chrome Safari Compatibility

2009-05-12 Thread Vitali Lovich

Difficult to determine the issue without the CSS  some sample code, it's
difficult to guess at the problem (might be a quirks issue).

On a side note, just to clarify that you explained yourself correctly,
hosted mode browser is only IE on Windows (at least until GWT 2.0).  Mozilla
on Linux.   Safari on OSX.

 In brief, -out becomes -war, and if you're interested in the non -

 I have completly no idea what's the reason of this problem. I've
 searched the web for solution but I couldn't find any. The server
 isn't mine so I think it may be problem in its configuration.   
 I'll be
 very grateful for any help.- Hide quoted text -

Re: new Compiler documentation


Sure, just fire up the compiler or hosted mode with an invalid option  
and it'll list all of the valid ones in the console for you. It is  
really helpful that way :-)

 Thanks for the link, but is there a page somewhere that just shows all
 the options for the new 1.6 Compiler and HostedMode apps?

 It would be nice if the Upgrade page (http://code.google.com/
 webtoolkit/doc/1.6/ReleaseNotes_1_6.html#Upgrading) contained info  
 on
 how to go from the GWTCompiler  to the newCompiler; just like it  
 does
 for Hosted Mode.

 Moreover. if there was a page explaining the command line options  
 then
 people would be able to figure out by themselves.

 This is hidden behind the the design document link about the new
 project 
 layout:http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6
 (look for the Command Line Options, old vs. new section)

 In brief, -out becomes -war, and if you're interested in the non -
 deployed linker artifacts (that were previously generated into the
 module-aux directory), you'd have to pass an explicit -extra
 argument giving the path to the extra output dir.
