 Hi fellows...
 I am faced with this difficult situation:

 I have a GWT application built in the RPC style for async calls (1
 Async interface, 1 RemoteService interface and 1 RemoteServiceServlet
 implementation) and now there is a requirement of sending some request
 parameters to each async call and I would like to perform this in a
 way the developer does not need to know about it (i.e. pass an object
 in every async call).

 I know if I were using RequestBuilder this would be a piece of cake,
 but I am not and it would require a *considerable* effort to change
 it.

 I was wondering if it's possible to extend the GWT.create to add a
 custom implementation that carries the parameters from the browser URL
 to all servlet calls... do you have any idea?

GWT 2.0 introduces a RpcRequestBuilder that you can use to tweak the
RequestBuilder that's used behind the scene for the RPC calls.

There's no API in GWT, you'd have to resort to using JSNI and cope for
browser-specific APIs (runtimeStyle in IE, computedStyle in others)

Defining a source package out of the module heirarchy (from a JAR for example)

2009-10-08 Thread Ittai


Hi,
I have a web-app which currently holds this structure:
-Web
--src
---com.company.web
module.gwt.xml
otherModule.gwt.xml
com.company.web.module
-com.company.web.module.client
-com.company.web.module.server
com.company.web.otherModule
-com.company.web.otherModule.client
-com.company.web.otherModule.server
com.company.web.common
-com.company.web.common.data
and so on.

I have in my com.company.web.common.data package classes which I
mark in my gwt.xml file as a source package because they need to be
used on the client side. So far so good.
However now in order to communicate with a different back-end app of
my company I need to have those classes in a whole different project
under com.company.common.data and I'm wondering if that's doable in
GWT?
I want to somehow specify in my gwt.xml file a fully qualified name as
another source package and have GWT compiler do its magic with it.
Let's say that I'll have those classes available as a JAR or as a
dependant project in eclipse to my project.

The only option I have in mind currently is to have in
com.company.common a dummy gwt.xml file and than to have my
module.gwt.xml inherit that dummy gwt.xml. This is ugly as this is not
really a module and the other apps using the common.jar won't really
need this file so I'd rather not go that way.

Thanks for any suggestion

Whats the connection URL

2009-10-08 Thread Nathan


Hi All,

I've been running GWT 2 m1 and all has been great. Recently however
when I start up the debugger the browser connection URL appear to be
showing in the eclipse Console window, it did used to and I'd paste
the URL into a browser to connect and debug. The debugger window
starts perfectly. Could someone please send me an example connection
URL and I'll try and use that format to guess mine. Would be much
appreciated.

Regards,

Nathan

Re: Dependency injection and GWT?

  Hi

  I want to build a view in GWT but it is one of a few different types of
  views. So I was thinking, I could
  have them all share something common via inheritance, so that I could inject
  any kind of view I'd like into my module...
  I'm having trouble binding one of those things together. Any help would be
  welcome...

  Here's the idea:

  The new abstract presenter that things will be based upon:

  public abstract class StepModulePresenterT extends
  StepModulePresenter.Display extends WidgetPresenterT {

      public interface Display extends WidgetDisplay {

      }

      @Inject
      public StepModulePresenter(T display, EventBus eventBus) {
          super(display, eventBus);
      }

  }

  It defines an interface that inherits the WidgetDisplay. Then for example, a
  particular type of StepModulePresenter would be:

  public class HistoryModulePresenter extends
  StepModulePresenterHistoryModulePresenter.Display {

      @Inject
      public HistoryModulePresenter(Display display, EventBus eventBus) {
          super(display, eventBus);
          bind();
      }

  ...

  }

  So my view can be defined as:
  public class HistoryModuleView extends Composite implements
  HistoryModulePresenter.Display {
      HistoryModuleView() { ... }

  }

  So far so good. Now I'd like to use my HistoryModuleView but passed in as a
  StepModule in my Main app view:

  public class MainView extends Composite implements MainPresenter.Display {
      @Inject
      public MainView(P1 p1, P2 p2, P3 p3,
  StepModulePresenterStepModulePresenter.Display module) { ... }

 HistoryModulePresenter is a
 StepModulePresenterHistoryModulePresenter.Display, not a
 StepModulePresenterStepModulePresenter.Display, so you can't use one
 for the other (well, you can, but you'll have an unchecked cast).

 I'd rather define the ctor as:
 @Inject
 public MainView(P1 p1, P2 p2, P3 p3, StepModulePresenter? extends
 StepModulePresenter.Display module) { ... }

  What I don't get is how to bind the HistoryModule as the thing that gets
  passed in here... And then later on, how I make it one of many things that
  can be passed in:

 Not tested, but you should be able to write:
 bind(new TypeLiteralStepModulePresenter? extends
 StepModulePresenter.Display() { }).to(HistoryModulePresenter.class);

Re: History with MenuBar

2009-10-08 Thread Robin


you can register a ClickHandler to your MenuItems.

instead of:
MenuBar fooMenu = new MenuBar(true);
fooMenu.addItem(the, cmd);

try:
MenuItem the = new MenuItem(the);
the.addClickhandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
  History.addItem(the);
  //do something else
}
});

Is it possible to send generic types over RPC?

2009-10-08 Thread andreas_b


Hi all.

I have searched the forum and google for some answers, but have been
unable to find a direct answer to my question. So sorry if this has
been answered. In that case, please give me the link to that
discussion.

I'm working on a project where I need to send lots of different data
object over RPC to save them in a database.
I thought, hey let's use some generics and let the type extends
Serializable.

So I defined the synchronous method like this:

T extends Serializable DBQueryResultT saveObject(T aObject);

and asynchronous version:

T extends Serializable void saveObject(T aObject,
AsyncCallbackDBQueryResultT callback);

All data types that I pass to this method implements Serializable and
I have verified that they can be sent when defining separate methods
for them. DBQueryResult has also been successfully serialized and
deserialized before I tried to make this generic.

I get no compilation errors, but during runtime (in hosted mode)I get
the following error:

2009-okt-08 10:21:42
com.google.appengine.tools.development.ApiProxyLocalImpl log
SEVERE: [1254997302431000] javax.servlet.ServletContext log:
DataServiceImpl: An IncompatibleRemoteServiceException was thrown
while processing this call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
This application is out of date, please click the refresh button on
your browser. ( Could not locate requested method 'saveObject

(RemoteServiceServlet.java:164)
at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost
(RemoteServiceServlet.java:86)
.


Is it not possible to use generics when defining RPC methods? Is there
any other way to avoid having to define separate methods for each data
object that I need to send over?

Thanks in advance!

BR, Andreas

Modular loading of widgets, is it possible?

2009-10-08 Thread balachandra maddina

Hi There,

  Im aware that GWT obfuscate the compiled javascript code well, but still i
dont want to load all my application javascript in one shot. im more
interested on loading different widgets as modules. one of the reasons is my
application is complex and code kept growing and i kept adding more events
to handle different views which resulted a not so friendly maintainable
system.

so what im planning to do is load a module when a link is clicked(event
triggering but not like a 100 events. thinking if i can manage all of them
with a few events) in my landing page and this module will have children and
all the necessary support for their rendering will be supported by the
parent(the module which is loaded). typically in my application ill be
having a number of these modules and the scariest part is most of them are
complex. so im very keen on not loading all the modules in one single big JS
file rather im planning to load them something similar to OpenSocial Gadgets
where an externally created component(gadget) can be loaded into the
container.

My question is, is this possible? if possible how can this be done?

any help on this would be very much appreciated(please...)

Thank you,
bala.

JavaMail problem with Tomcat (not AppEngine)

2009-10-08 Thread AndrewG


I am having problem with an e-mail alert system that runs using
JavaMail. This runs server-side under Tomcat and sends out warnings
when things go wrong. I have now introduced gwt front-end components -
but am deploying and running under Tomcat - not Google App Engine (App
engine box not ticked in eclipse project google properties either).
All of the jars that are usually necessary for JavaMail are on the
classpath.

It looks as if the JavaMail transport is being 'hijacked' in the way
that I believe it is supposed to do when running under AppEngine - but
I am not running it under AppEngine - it is using Tomcat.

The errors look like:

Error: com.google.apphosting.api.ApiProxy$CallNotFoundException: The
API package 'mail' or call 'Send()' was not found.
com.google.apphosting.api.ApiProxy$CallNotFoundException: The API
package 'mail' or call 'Send()' was not found.

which clearly suggests that mail operations are being handled via a
google apphosting component - not the expected ones.

The e-mail error handlers are all in a separate utility project - so I
just want to re-use them - not change them.

Anybody know how to get around this ?

Andrew

 The UI freezes just like before but when I create my own launch there is
 no problem

 Can someone confirm if this bug still exists for OOPHM on the mac with
 Eclipse 3.5 or is my setup wrong?

 Thanks,

 Hey John,
 Were you attempting to launch in Out-of-process-hosted-mode? If so, there
 was a bug that was fixed in version 1.1.1 of the plugin where the
 -XstartOnFirstThread argument was being added to out-of-process-hosted-mode
 launch configurations. This was not the correct behavior, and would have
 resulted in the problem that you were seeing.

 not effect you if you are not running from trunk.

 i'm running gwt with eclipse and on osx leopard too and haven't had
 any problems with it for years, so i would guess that the problem will
 be hidden somewhere in your code. You might try to uncomment
 temporarily parts of your code that you could think problematic and
 see if that fixes it and thus being able to track down the exact point
 that is causing that problem.

  I am using gwt trunk with Eclipse on a os x leopard and find that the
  hosted mode is almost too slow to use.  For example, clicking on a
  StackLayoutPanel header to change panels causes both Firefox and

  Is this unusual or related to the hosted mode UI freezing up due to
  the -XStartOnFirstThread bug?  I haven't profiled it yet to see where
  the issue is but the fact that it occurs on the stack panel switch

Howto add an external jar into GWT project

2009-10-08 Thread mag


I am trying to add a jar into the Stockwatcher project found in the
tutorial but I am getting the message:
[ERROR] Line 48: No source code is available for type
org.apache.commons.math.util.MathUtils; did you forget to inherit a
required module?
when trying to run it.

The jar I used is http://mvnrepository.com/artifact/commons-math/commons-math
and I only use this jar to test if it works to add a self contained
jar into a GWT project. I selected Stockwatcher in eclipse and
selected Build Path- Configure Build Path from the context menu
and selected Libraries tab and thereafter pressed the Add External
JARs button to add the jar.


This makes me wonder how it all works, can I not add external jar
files to a GWT project unless I have the source code or am I doing it
wrong, have googled and seen that some are talking about modifying the
project.gwt.xml file but I don't see that file in the Stockwatcher
project.

I have also read that I can't add a service layer jar which I also
were planning. Apparently I need to communicate with a service layer
via RPC and I can't use annotations in my DTO classes which troubles
me since I want to use hibernate. Is this still true in the latest
version of GWT and can explain why or point out some documentation I
should read to understand this better, thanks!

Usage of HasAllMouseHandlers interface.

2009-10-08 Thread AndyB


I am having difficulty understanding the usage of the
HasAllMouseHandlers interface.

I have been learning how to develop with GWT by reading the GWT
Applications book but a lot of the code has been depreciated.

In one of the sample applications, the depreciated SourceMouseEvents
interface is used as follows:

public class GadgetContainerView extends SimplePanel implements
SourceMouseEvents
{
  public void addMouseListener(MouseListener listener)
  {
title.addMouseListener(listener);
  }

  public void removeMouseListener(MouseListener listener)
  {
title.removeMouseListener(listener);
  }
}

And then later in a containing class it uses the public void
onMouseDown(Widget sender, in x, int y){  } method.

I have been trying to figure out how to do this by using the
HasAllMouseHandlers but I cant figure it out.
Could someone explain it for me please?

Thanks for reading,
Andy

Re: Is it possible to send generic types over RPC?

2009-10-08 Thread Paul Robinson


I believe you've found this bug:
http://code.google.com/p/google-web-toolkit/issues/detail?id=2374

andreas_b wrote:
 Hi all.

 I have searched the forum and google for some answers, but have been
 unable to find a direct answer to my question. So sorry if this has
 been answered. In that case, please give me the link to that
 discussion.

 I'm working on a project where I need to send lots of different data
 object over RPC to save them in a database.
 I thought, hey let's use some generics and let the type extends
 Serializable.

 So I defined the synchronous method like this:

 T extends Serializable DBQueryResultT saveObject(T aObject);

 and asynchronous version:

 T extends Serializable void saveObject(T aObject,
 AsyncCallbackDBQueryResultT callback);

 All data types that I pass to this method implements Serializable and
 I have verified that they can be sent when defining separate methods
 for them. DBQueryResult has also been successfully serialized and
 deserialized before I tried to make this generic.

 I get no compilation errors, but during runtime (in hosted mode)I get
 the following error:

 2009-okt-08 10:21:42

 .


 Is it not possible to use generics when defining RPC methods? Is there
 any other way to avoid having to define separate methods for each data
 object that I need to send over?

 Thanks in advance!

Re: Defining a source package out of the module heirarchy (from a JAR for example)

2009-10-08 Thread Ittai


I've thought some more about what you said and I'm still not sure of
how this can work:
If I add a common.jar to my project then where can I put the
commonData.gwt.xml file?
If I need to create a false com.company.common package on my Web
project that will only hold my gwt.xml file then that sounds just
wrong.
Otherwise I'm not sure how this can be done as the source packages for
a module can only be its own packages or its sub-packages .

   Let's say that I'll have those classes available as a JAR or as a

   The only option I have in mind currently is to have in

  That's the way to go however; though you don't have to put the gwt.xml
  within the JAR, you can just have it in the appropriate package in
  your GWT project only (that's the magic of the Java classpath, it's
  unrelated to where on disk the files live)

Emne: Modular loading of widgets, is it possible?

Hi There,

  Im aware that GWT obfuscate the compiled javascript code well, but still i
dont want to load all my application javascript in one shot. im more
interested on loading different widgets as modules. one of the reasons is my
application is complex and code kept growing and i kept adding more events
to handle different views which resulted a not so friendly maintainable
system.

so what im planning to do is load a module when a link is clicked(event
triggering but not like a 100 events. thinking if i can manage all of them
with a few events) in my landing page and this module will have children and
all the necessary support for their rendering will be supported by the
parent(the module which is loaded). typically in my application ill be
having a number of these modules and the scariest part is most of them are
complex. so im very keen on not loading all the modules in one single big JS
file rather im planning to load them something similar to OpenSocial Gadgets
where an externally created component(gadget) can be loaded into the
container.

My question is, is this possible? if possible how can this be done?

any help on this would be very much appreciated(please...)

Thank you,

Re: OOPHM GWT 2.0 Milestone 1 on Mac

2009-10-08 Thread Christian Goudreau

Here's some update :

I installed another instance of eclipse, installed the GWT plugin and then
added GWT 2.0.

I create a new project, runned it and everything worked fine exept that the
development mode window is bugued and I can't close it without closing
Eclipse... Debug is working fine tought and when I stop it, the development
mode window is closing properly.

So I inspected the build order, I came back to my old eclipse with my
project that didn't want to work, I put GWT sources on top of everything but
the project sources. I runned it and... it RAN ! But their is a BIG weird
thing... I created a new project in my new Eclipse... and now I get the new
project html page instead of the old one ! The java is fine, but not what
was in the WAR folder. LOL

I'll run other test, but I think the only error that I had what the source's
order.

Re: hosted mode debugging with -noserver in eclipse

2009-10-08 Thread Keith Platfoot

Hi Mike,
I think your issue has to do with certain changes made to GWT in version
1.6.  Before 1.6, the GWTShell class was used to launch applications in
hosted mode.  In 1.6, the default structure of GWT projects was changed to
make it more similar to Java web apps.  By convention, GWT projects now
assume the existence of a directory named war which contains the contents
of the deployed WAR file.  This includes source files, such as your web.xml
and any public HTML pages.  The WAR directory also contains subdirectories
with the compiled JavaScript output of each GWT module.  In 1.6 and later a
new class, HostedMode, replaces the older GWTShell as the default class for
launching hosted mode.

The plugin supports GWT versions both older and newer than 1.6.  It uses
some heuristics to determine whether to launch applications with the
GWTShell or HostedMode class.  It sounds like in your case, you are able to
use HostedMode from the command line, but when you launch from Eclipse, the
plugin is using GWTShell... is that correct?

If so, I have two follow-up questions.  First, does your project contain a
WAR directory named war?  I know that many maven users use a different
naming convention, but as of right now, the plugin does *not* support
configuring the name of the WAR directory (it must be war).  If yours is
named differently, your best bet might be to try to create a symlink named
war pointing to your actual WAR folder.  I haven't actually tested that
scenario, but it *should* work.

Once your project has a proper war directory (or symlink), the second
thing to check is whether your project is tagged as a Google Web Application
project.  This won't actually show up in the Eclipse UI, but if you look at
your project's .project file, you should see the following tag nested under
natures

naturecom.google.gdt.eclipse.core.webAppNature/nature

If it's *not *there, go ahead and add it, and then restart Eclipse.  Then
try launching the project again, and see what happens.  Let me know if you
still run into problems.

Keith

 Just to follow up on this ... this seems to be the eclipse plugin,

 The weird thing is, it DOES work with a small war project that I

 how to debug the eclipse plugin.

 I've added the command line startup command into my eclipse run so I
 can debug but it would be better if the plugin worked :(

Any guidance for the following problem would be appreciated.

I am in the process of converting an existing GWT 1.5 project to GWT
1.7 and getting the following error.

[ERROR] Type

Not sure how to fix this error.

All the classes listed below implement IsSerializable.

Not sure which class has to be fixed first.

Re: GWT PHP HTML 5 interaction

2009-10-08 Thread skorpiostinger


Great !!!

I have already downloaded eclipse, gwt plugin for eclipse, Tomcat,
ANT.

Also I have Apache/PHP/MYSQL are up and running at my RHE 5 Linux
server machine. The only conclusion I have right now how they would be
interacting between each other.

I do not want to maintain to servers TOMACT/APACHE ... it would give
more pain I guess.

I understand I have to create a very small PHP application and full
GWT interfaze client side application. It would be part of existing
php application (header, top and main menu) and GWT widgets would be
add some extra functionality as part of the whole system to upgrade
usability and lookfeel deisgn for my Email Template Blast engine.

--
PHP:  ?php showTopMenu()?
--
GWT: scrip JStunction showEmailBlastElementByName();/script
--

Here is database interaction scheme:


--php---MENU(DB(MySQL))---JSON,GWT rpc--TEMPLATE
(XML)JSON, phpDRAFTS(DB(MYSQL)---php mail()-


I see the issues right now.

- interaction between Java Script/PHP server speed optimization;

- technical implementation and maintenance;

- HTML 5, cross-browser support;

My research worked out the following:

Here is an excellent XML, GWT, and PHP Tutorial at ibm.com/
developerworks that explains the bridge between GWT and PHP using XML

http://download.boulder.ibm.com/ibmdl/pub/software/dw/xml/x-gwtphp/x-gwtphp-pdf.pdf

I used work with Java servers and the problem I had was the speed.

PHP engine has definitely an excellent speed.

To be continued ...

 Hi,

 to be honest I'm no php guy, so I'm not sure about the implementation  
 details of the hessian control on php side.

 on gwt side you simply implement an interface, for example like this

 public interface HelpHessianService {

         public ListString getHelpTopics(String search);

 }

 and you then instantiate this interface via a helper method

 import com.caucho.hessian.client.HessianProxyFactory;

                         String hostUrl = getHostUrl(request);
                         String url = hostUrl + /index.php?
 main_page=gwt_handlerhessian=true;
                         HessianProxyFactory factory = new 
 HessianProxyFactory();
                         HelpHessianService helpHessianService =  
 factory.create(HelpHessianService.class, url);

 and then you can just call helpHessianService.getHelpTopics(search);

  Thank you,

  Dominik for your prompt reply.

  It is sounds great to me. I have a feeling I could provide  
  connection through the hessian web service to PHP application to get  
  some of the services from the PHP/Apache application.

  Also I have researched in the web and found the Hessian PHP Client/

  Dominik, how the hessian protocol is basically operate the data from  
  the PHP/Apache and
  GWT/Tomcat.

  More details appreciated.

Re: Announcing GWT 2.0 Milestone 1

2009-10-08 Thread Sky


I got debugging to work!

I created a new GWT web app with the Eclipse google plugin using GWT
2.0MS1 as the SDK. This is what most likely solved my problem. Simply
changing a project from GWT 1.7.1 to 2.0 must not be making all the
necessary changes to the auto generated files to be properly
compatible. Obviously this sort of thing will be ironed out for
release.

Then I needed to first launch (not a debug launch) the newly created
GWT web app (with the default app still intact). I tried this with a
browser that did not have the plugin installed (FF3.5) and when
navigating to the URL it auto directed me to the plugin install web
page and after installing the plugin the web app was rendered
correctly. Note that at this point I have not compiled the app so the
plugin is indeed doing its job! The java code is what is interacting
synchronously with the browser instead of the compiled JS!

Note that I had first attempted to launch the app in debug mode which
gave me 3 errors related to the Appengine
(com.google.apphosting.utils.jetty... yet eclipse could not resolve
com.google.apphosting.utils.jetty) but those errors went away as soon
as I did a non debug launch. In other words, the app was able to do a
debug launch only after doing a regular launch.

With the debug launch successful I was able to hit a breakpoint in the
onModuleLoad method of this default web app! I then copied all the
required files from my previous project into this new one. Once again
I was able to hit a breakpoint on the onModuleLoad method!

I am very excited to have this working!

   Hi everyone,

   We are excited to release the first milestone build for GWT 2.0 today.
   This milestone provides early access (read: known to still be
   unfinished and buggy) to the various bits of core functionality that
   will be coming in GWT 2.0. Please download the bits from:

  http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=2

   Things that are changing with GWT 2.0 that might otherwise be
   confusing without explanation
   * Terminology changes: We're going to start using the term
   development mode rather than the old term hosted mode. The term
   hosted mode was sometimes confusing to people, so we'll be using the
   more descriptive term from now on. For similar reasons, we'll be using
   the term production mode rather than web mode when referring to
   compiled script.

   * Changes to the distribution: Note that there's only one download,
   and it's no longer platform-specific. You download the same zip file
   for every development platform. This is made possible by the new
   plugin approach used to implement development mode (see below). The
   distribution file does not include the browser plugins themselves;
   those are downloaded separately the first time you use development
   mode in a browser that doesn't have the plugin installed.

   Functionality that will be coming in GWT 2.0
   * In-Browser Development Mode: Prior to 2.0, GWT hosted mode provided
   a special-purpose hosted browser to debug your GWT code. In 2.0, the
   web page being debugged is viewed within a regular-old browser.
   Development mode is supported through the use of a native-code plugin
   for each browser. In other words, you can use development mode
   directly from Safari, Firefox, IE, and Chrome.

   * Code Splitting: Developer-guided code splitting allows you to chunk
   your GWT code into multiple fragments for faster startup. Imagine
   having to download a whole movie before being able to watch it. Well,
   that's what you have to do with most Ajax apps these days -- download
   the whole thing before using it. With code splitting, you can arrange
   to load just the minimum script needed to get the application running
   and the user interacting, while the rest of the app is downloaded as
   needed.

   * Declarative User Interface: GWT's UiBinder now allows you to create
   user interfaces mostly declaratively. Previously, widgets had to be
   created and assembled programmatically, requiring lots of code. Now,
   you can use XML to declare your UI,

Avoiding RPC Coming in to an inactive client from the server.

2009-10-08 Thread Danny


My application has a timeout on the client side that often causes the
client to go away while there is a pending RPC return from the
server.  Nothing comes crashing down, but Tomcat fills its log with:

org.apache.catalina.core.ApplicationContext log
SEVERE: Exception while dispatching incoming RPC call
java.io.IOException...

followed by a stack printout.

Does anyone know how to relieve Tomcat of this burden and my having to
dump its log file more frequently that I would like?

Thanks,

Danny

Integrating GWT with JSP

The application's UI is developed using JSP.

Can someone suggest me the best practices followed in communicating

GWT incubator PagingScrollTable

2009-10-08 Thread davis


Hi, I'm not sure where to post for incubator -- it doesn't have its
own mailing list.

I'm trying to use the PagingScrollTable widget from incubator.  It
seems to work just great except I cannot get the columns to sort.
From my understanding, there is a built-in quicksort implementation
that you can override if you wish.  QS should work fine for me.  I
have a simple table model here with two columns (firstName, lastName)
and the datatype is a string.

A sample onModuleLoad app using the PagingScrollTable is pasted below
that sets up some mock data.  I may just be using the API incorrectly,
but I can't see it.  Documentation is sparse.

Anyone have any insight on this??

Thanks in advance,
Davis

Re: Announcing GWT 2.0 Milestone 1

I have noticed that if you use Google Plugin to launch your project
with 2.0 jar. The development shell does not launch at all. You have
to launch it as a Java Application and set up some parameters by
yourself, then you are able to see that GWT Develop Mode popup shell
window. Is my observation correct?

Ben, with 2.0 my projects launch the development shell when using the
Google plugin launch options. It launched for me even when I just
changed a project from 1.7.1 to 2.0, but you could try creating a
whole new project with 2.0 from the start and copy the files over from
the old project.

Make sure the google plugin and the appengine is fully up to date.
What version of Ecipse are you using? Try downloading the new 3.5.1
version.

Sorry I can't help any more than that. gl

  I got debugging to work!

  I created a new GWT web app with the Eclipse google plugin using GWT
  2.0MS1 as the SDK. This is what most likely solved my problem. Simply
  changing a project from GWT 1.7.1 to 2.0 must not be making all the
  necessary changes to the auto generated files to be properly
  compatible. Obviously this sort of thing will be ironed out for
  release.

  Then I needed to first launch (not a debug launch) the newly created
  GWT web app (with the default app still intact). I tried this with a
  browser that did not have the plugin installed (FF3.5) and when
  navigating to the URL it auto directed me to the plugin install web
  page and after installing the plugin the web app was rendered
  correctly. Note that at this point I have not compiled the app so the
  plugin is indeed doing its job! The java code is what is interacting
  synchronously with the browser instead of the compiled JS!

  Note that I had first attempted to launch the app in debug mode which
  gave me 3 errors related to the Appengine
  (com.google.apphosting.utils.jetty... yet eclipse could not resolve
  com.google.apphosting.utils.jetty) but those errors went away as soon
  as I did a non debug launch. In other words, the app was able to do a
  debug launch only after doing a regular launch.

  With the debug launch successful I was able to hit a breakpoint in the
  onModuleLoad method of this default web app! I then copied all the
  required files from my previous project into this new one. Once again
  I was able to hit a breakpoint on the onModuleLoad method!

  I am very excited to have this working!

 Hi everyone,

 We are excited to release the first milestone build for GWT 2.0 today.
 This milestone provides early access (read: known to still be
 unfinished and buggy) to the various bits of core functionality that
 will be coming in GWT 2.0. Please download the bits from:

http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=2

 Things that are changing with GWT 2.0 that might otherwise be
 confusing without explanation
 * Terminology changes: We're going to start using the term
 development mode rather than the old term hosted mode. The term
 hosted mode was sometimes confusing to people, so we'll be using the
 more descriptive term from now on. For similar reasons, we'll be using
 the term production mode rather than web mode when referring to
 compiled script.

 * Changes to the distribution: Note that there's only one download,
 and it's no longer platform-specific. You download the same zip file
 for every development platform. This is made possible by the new
 plugin approach used to implement development mode (see below). The
 distribution file does not include the browser plugins themselves;
 those are downloaded separately the first time you use development
 mode in a browser that doesn't have the plugin installed.

 Functionality that will be coming in GWT 2.0
 * In-Browser Development Mode: Prior to 2.0, GWT hosted mode provided
 a special-purpose hosted browser to debug your GWT code. In

Re: SerializationException is lost

2009-10-08 Thread Sripathi Krishnan

Deliberate decision ..

Few reasons that I know of --

a) Server code is capable of generating exceptions which can't be translated
to javascript. Things like HibernateException can't be translated to JS.
b) From a security perspective, you don't want your server side stack traces
to be available to end-users.
c) Assuming GWT could throw the exception to JS, it would have to be capable
of generating serialization/deserialization code for every exception object
in the classpath. Imagine your RPC method is like this -

public ResultDTO getSomeInformation(InputDTO obj) throws Exception;

Now, your java code could throw any sub-class of Exception and GWT doesn't
have a way to figure that out at compile time. So, it would have to convert
every Exception sub-class into appropriate JS code -- which leads to a huge
js file.

Because of this, GWT requires that you explicitly declare any exceptions you
want available in your javascript code in the throw clause of your RPC
method.

Using External Jars in Eclipse

2009-10-08 Thread Rakmos


I have been searching for several hours for some type of a tutorial on
how to do this.  I was wanting to use some widgets from GwtExt because
of their easy validation methods, but cannot seem to get my webapp to
compile.

I have linked the jar file as an external jar, and it shows up under
Referenced Libraries in the Package Explorer in eclipse.

Do I need to add a source tag in the gwt.xml file for my webapp?  If
so, what is the format of this tag?

Also, I keep seeing the term java classpath.  What does that mean?  Is
that was appears in the Package Explorer under src?

The error message is :

Unable to find 'com/gwtext/client/widgets/form/TextField.gwt.xml' on
your classpath; could be a typo, or maybe you forgot to include a
classpath entry for source?

I just installed the GWT plugin for eclipse. Does that mean that I

Trying to create a generic LoginManager

2009-10-08 Thread Tone


I'm just getting into GWT and getting back into Java after a 9 year
absence. As I'm creating my first project it was pretty clear that I
never wanted to write login  session handling code ever again so I've
been trying to create a reusable class for all of this that I can
(mostly) drop into future projects.

I was hoping to have the class able to alert any other classes and
panels on the site when the user logs in asynchronously. Listeners and
Handlers didn't seem to be the right tool for the job. And I really
don't want to put all the other classes for this site under the
LoginManager. What would be the preferred way of having external
classes know when the results of an Ajax call come through?

why does GWT Showcase continually re-request CSS image under IE6

2009-10-08 Thread jmcmd


Under IE6 my application grinds to a halt because the GWT appears (i
might be wrong) to somehow force IE6 to re-load all my CSS images any
time their is a UI event where I make a Widget visible - even if that
image is already visible on the screen. I can see the requests (and
subsequent 304 response codes) in the GWT console.

I've tested this behavior using GWT's Showcase and anyone can clearly
see this same behavior.
I have tried every server-side setting for the response headers and it
did not change a thing.

I thought this might be a Ajax/IE6 problem but a similar functionality
using ICEFaces ( a different Ajax framework) worked - meaning that IE6
only requested the CSS image once and only once.

I've searched all over these groups and saw nothing specifically
addressing this issue. My app (and the showcase app) work perfectly
normal under IE7/IE8,FF, Safari so this only appears to be IE6
related.

I can't be the only one who observed this issue - perhaps I'm missing
something obvious, but any help or guidance is greatly appreciated.

My app is more or less un-usable in IE6 because I have about 80 css
images and having IE6 make 80 request every time I make a various
visible makes for a very sluggish experience.

In great need of help

Qestion on Focus Panel

2009-10-08 Thread sri


Hello,
Does Focus panel that has Focus recieve an onBlurEvent if mouse is
clicked on one of its children?I have a focus panel with a Grid as its
child. I want to close the Focus Panel when clicked outside the focus
panel - so I have a BlurHandler defined. But when I click inside the
Focus panel ( on one of the cells of the Grid ) the Grid's
onCellClicked is never called - instead the BlurHandler onBlur is
called. Do I need to do anything specific to not trigger onBlur when a
child is clicked?

Re: rpc serialization problem

2009-10-08 Thread brancoch


The problem comes from instrumentation done by the ORM. Most of the
ORM substitute the implementation of the List, Map or Set with their
own implementation since they need to track invocation of method of
the collection. I know that the latest GWT 2.0 code base is putting
code in the RPC framework to support JDO so this is probably why it is
working.
Note that relationship to the one side (for example a Customer entity)
in JPA will likely be instrumented as well.

In my project where we are using Hibernate, I have minimally enhanced
the RPC framework (ServerSerializationStreamWriter.java,
SerializabilityUtil.java) to workaround this issue.

I know other framework are trying to solve this problem but I find my
approach more efficient in term of performance even if it is less
flexible (need to be adapted for other ORM).

I suspect that it should be easy to adapt my approach for DataNucleus.

Let me know if you would like to see the coce?

2.0 m1 Duplicate Signature class loading issue in Hosted Mode Console

2009-10-08 Thread pmonestie


Hi,
First congrats on this release this is awesome!!
 I've been using 2.0 from the trunk for a while now and the following
problem has been there for a while, using oophm:
When I change a class that is serialized between client and server I
get a Duplicate signature exception (in the hosted mode console) upon
reloading the app.

The error goes away when restarting the HostedMode console (OOPHM)

I get:
[ERROR] Unable to load module entry point ...
java.lang.RuntimeException: Deferred binding failed for
'MyService' (did you forget to inherit a required module?)
at com.google.gwt.dev.shell.GWTBridgeImpl.create(GWTBridgeImpl.java:

Caused by: java.lang.AssertionError: Duplicate signature
MySerializableClass/4200318118

(SerializerBase.java:82)

Apparently the HostedMode console doesn't realize that it should
reload the class I just changed.
I'm wondering if there is anything I can do about this?
Thanks.

Custom Designed Sign in page?

2009-10-08 Thread jlc488


Hello guys...

I am not sure if I am suck at googling or what.

I just can not find the way of implementing  custom made signin page.

So, This is my question. I am currently using UserService and User
class that provided by google appengine .

UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();

something like above.

Somehow, this way keep forward google accounts sign in page which I
want to use a custom made sign in page.

Is it possible?

Just few weeks or before, http://kabbalistic-joke-number.appspot.com/login.jsp
this site method was working and it is not working now.  :-

This one also redirects to the google accounts sign in page.

Is there anyone know how to implement my own sing in page without
redirecting google accounts ?

Re: GWT PHP HTML 5 interaction

2009-10-08 Thread skorpiostinger


Hi!

In my case, I run PHP via Apache, and I use straightforward AJAX calls
from GWT. PHP never knows about GWT; it just delivers XML or JSON. GWT
doesn't mind about PHP; it just receives the XML or JSON data,
processes it, and goes on. You won't need Tomcat (or JBoss or anything
like that) unless you are using GWT RPC; if your server side only runs
PHP, Apache will be enough.

Maybe this article I wrote for IBM could help you? I also wrote this
article for Linux Journal, on other methods for getting JSON, and this
other IBM article on processing XML. Please let me know if you have
further questions.

Best regards,
Federico Kereki

 I have already downloaded eclipse, gwt plugin for eclipse, Tomcat,

 I do not want to maintain to servers TOMACT/APACHE ... it would give
 more pain I guess.

 I understand I have to create a very small PHP application and full
 GWT interfaze client side application. It would be part of existing
 php application (header, top and main menu) and GWT widgets would be
 add some extra functionality as part of the whole system to upgrade

 PHP:  ?php showTopMenu()?

 Here is database interaction scheme:

 --php---MENU(DB(MySQL))---JSON,GWT rpc--TEMPLATE
 (XML)JSON, phpDRAFTS(DB(MYSQL)---php mail()-

 I see the issues right now.

 - interaction between Java Script/PHP server speed optimization;

 - technical implementation and maintenance;

 - HTML 5, cross-browser support;

 My research worked out the following:

 Here is an excellent XML, GWT, and PHP Tutorial at ibm.com/
 developerworks that explains the bridge between GWT and PHP using XML

 http://download.boulder.ibm.com/ibmdl/pub/software/dw/xml/x-gwtphp/x-...

 I used work with Java servers and the problem I had was the speed.

 PHP engine has definitely an excellent speed.

  on gwt side you simply implement an interface, for example like this

   Thank you,

   Dominik for your prompt reply.

   It is sounds great to me. I have a feeling I could provide

   Also I have researched in the web and found the Hessian PHP Client/

   Dominik, how the hessian protocol is basically operate the data from

 I'm just getting into GWT and getting back into Java after a 9 year
 absence. As I'm creating my first project it was pretty clear that I
 never wanted to write login  session handling code ever again so I've
 been trying to create a reusable class for all of this that I can
 (mostly) drop into future projects.

 I was hoping to have the class able to alert any other classes and
 panels on the site when the user logs in asynchronously. Listeners and
 Handlers didn't seem to be the right tool for the job. And I really
 don't want to put all the other classes for this site under the
 LoginManager. What would be the preferred way of having external
 classes know when the results of an Ajax call come through?

Re: Integrating GWT with JSP

2009-10-08 Thread venki


You have to use JSNI(Java Script Native Interface) which is provided
by GWT. Using this you can able to access java script code of your jsp
page. If you wish to send any data from your jsp to GWT module then
export that variable in java script of your jsp page. In your module
write one JSNI method and write your stuff to take the data from your
java script code of jsp page.

Re: MapWidget.removeControl() not working?

2009-10-08 Thread lumo

noone got an idea about that?
do i have to call an update function afterwards?

2009/10/6 lumo lumo2...@gmail.com


 Hi NG!

 i add controls to my map on startup, but i want to enable the user to
 remove it again on runtime (toggle)

 so i init my map like this:

 private static MapTypeControl mapTypeControl = new MapTypeControl();
 private static ScaleControl scaleControl = new ScaleControl();

 public void onModuleLoad() {
 ...
mapWidget.addControl(mapTypeControl);
mapWidget.addControl(scaleControl);
 ...
 }

 further i got two functions to add/remove the controls via javascript:

public static void removeControls() {
Maps.logWrite(going to removeControls());
mapWidget.removeControl(scaleControl);
mapWidget.removeControl(mapTypeControl);
Maps.logWrite(done);
}

public static void addControls() {
mapWidget.addControl(scaleControl);
mapWidget.addControl(mapTypeControl);
}

 note: when i run the funtion via js, i even get the log! but the
 control does not get removed.

/**
 * all functions defined in this block will be visible as JavaScript
 * functions in the map (html)
 */
public static native void exportStaticMethod() /*-{
$wnd.removeControls =
 @at.biooffice.map.client.BioOffice3Map::removeControls();
$wnd.addControls =
 @at.biooffice.map.client.BioOffice3Map::addControls();
}-*/;

 any ideas whats going wrong?

 * Changes to the distribution: Note that there's only one download,
 and it's no longer platform-specific. You download the same zip file
 for every development platform. This is made possible by the new
 plugin approach used to implement development mode (see below). The
 distribution file does not include the browser plugins themselves;
 those are downloaded separately the first time you use development
 mode in a browser that doesn't have the plugin installed.

  Does not work for me on Vista x64.

  FF 3.5.3 can not install plugin.
  When I try to install extension, it goes further, but still fails
with some deferred binding exception.

  oophm.dll just can not be registered, may be because of x64?

@jgw I think it makes sense to have view objects initialized from a .ui.xml  
file as a whole. Since `DialogBox` is a view, why do I have to describe  
dialog's content in xml and at the same time initialize dialog itself (set  
its caption, other view related properties like animationEnabled etc) in my  
code?

And more general question: I am trying to understand if it is possible to  
follow MVP pattern with UiBinder, e.g. can I follow practices described at  
Google I/O and in

 Are you running a special 64-bit build of Firefox?  The official builds are
 only 32-bit and that is all we support at the moment.

  No, I use 32-bit FireFox, just x64 OS.



  oophm.dll just can not be registered, may be because of x64?



 Correct -- that is a 32-bit DLL and will not work with a 64-bit IE.  The
 simple attempt at compiling the same thing in 64-bit mode (the oophm64.dll
 listed below) does not work, and it will probably be a while before that can
 be addressed.

  I've downloaded 
http://google-web-toolkit.googlecode.com/svn/trunk/plugins/ie/prebuilt/oophm64.dll
but regsvr32 oophm64.dll still fails because Can not call

[gwt-contrib] Comment on UiBinder in google-web-toolkit


Comment by dygger:

BTW, I have found a workaround for the DialogBox problem.

At first I had to create a subclass for DialogBox implementing HasWidgets  
interface:

{{{
public class HasWidgetsDialogBox extends  
com.google.gwt.user.client.ui.DialogBox
 implements HasWidgets {
 @Override
 public void add(Widget w) {
 Widget widget = getWidget();
 if (widget != null  widget instanceof HasWidgets) {
 ((HasWidgets) getWidget()).add(w);
 } else {
 super.add(w);
 }
 }
}
}}}

Then goes my test Dialog (note it is the owner of its controls):

{{{
public class TestDialogBox extends HasWidgetsDialogBox {

 @UiTemplate(TestDialogBox.ui.xml)
 interface MyUiBinder extends UiBinderTestDialogBox, TestDialogBox {
 }

 private static MyUiBinder uiBinder = GWT.create(MyUiBinder.class);

 @UiField
 Label labelTextToServer;
 @UiField
 Label labelServerResponse;
 @UiField
 Button buttonClose;

 public TestDialogBox() {
 uiBinder.createAndBindUi(this);
 }

 @UiFactory
 protected TestDialogBox createDialog() {
 return this;
 }

 @UiHandler(buttonClose)
 protected void doClose(ClickEvent event) {
 this.hide();
 }
}
}}}


And finally corresponding .ui.xml:
{{{
gwt:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
   xmlns:gwt='urn:import:com.google.gwt.user.client.ui'
   xmlns:my='urn:import:yd.tests.gwt.client'
 my:TestDialogBox text=Remote Procedure Call animationEnabled=true

[gwt-contrib] Comment on UiBinder in google-web-toolkit


Comment by rj...@google.com:

I agree on the DialogBox use case, and will try to make it work. Thanks for  
the workaround.

[gwt-contrib] Comment on UiBinder in google-web-toolkit


Comment by rj...@google.com:

Oh, and yes: UiBinder gets along just fine with MVP. One thing I want to  
start experimenting with is having binder instances injected by GIN, e.g.:

{{{
MyView extends Widget {
   public interface Binder extends UiBinderMyView, Widget {}
   private static final Binder defaultBinder = GWT.create(Binder.class);

   public MyView() {
 this(defaultBinder);
   }

   @Inject
   public MyView(Binder binder) {
 binder.createAndBindUi(this);
   }
}
}}}

Although this will require making UiFields public, which is kind of gross.

Are you running into any particular problems?

[gwt-contrib] [google-web-toolkit] r6323 committed - Various fixes for deRPC....


Revision: 6323
Author: b...@google.com
Date: Thu Oct  8 10:06:39 2009
Log: Various fixes for deRPC.
- If an array type is artificially rescued, it should rescue its component  
type.
- Don't generate bad RPC proxy code if the legacy type-elision flag is set.
- Correctly handle CustomFieldSerializers that write null Strings.

[gwt-contrib] Comment on UsingOOPHM in google-web-toolkit


Comment by myonceinalifetime:

I got debugging to work!

I created a new GWT web app with the Eclipse google plugin using GWT 2.0MS1  
as the SDK. This is what most likely solved my problem. Simply changing a  
project from GWT 1.7.1 to 2.0 must not be making all the necessary changes  
to the auto generated files to be properly compatible. Obviously this sort  
of thing will be ironed out for release.

Then I needed to first launch (not a debug launch) the newly created GWT  
web app (with the default app still intact). I tried this with a browser  
that did not have the plugin installed (FF3.5) and when navigating to the  
URL it auto directed me to the plugin install web page and after installing  
the plugin the web app was rendered correctly. Note that at this point I  
have not compiled the app so the plugin is indeed doing its job! The java  
code is what is interacting synchronously with the browser instead of the  
compiled JS!

Note that I had first attempted to launch the app in debug mode which gave  
me 3 errors related to the Appengine (com.google.apphosting.utils.jetty...  
yet eclipse could not resolve com.google.apphosting.utils.jetty) but those  
errors went away as soon as I did a non debug launch. In other words, the  
app was able to do a debug launch only after doing a regular launch.

With the debug launch successful I was able to hit a breakpoint in the  
onModuleLoad method of this default web app! I then copied all the required  
files from my previous project into this new one. Once again I was able to  
hit a breakpoint on the onModuleLoad method!

I am very excited to have this working!

I think it would be better to call the other constructor to to avoid

specified to prevent a blank page from loading.  However, this causes
FF2 to open the error console with no error message.

Fix:
Changed the href to the correct value javascript:;.  Notice the ; on
the end to close the javascript expression.

Testing:
Verified this works on all browsers.

[gwt-contrib] Comment on UiBinder in google-web-toolkit


Comment by sven.tiffe:

Folks,

is there a way to bind more than one element to a method, e.g.

{{{
   @UiHandler(textField1)
   @UiHandler(textField2)
   protected void updateLogin(KeyUpEvent event) {
 model.validate();
   }
}}}

And is there anything planned for two-way bindings? I was playing around  
with gwittir but I was not very happy with it so far. I like the UIBinder  
approach which makes accessing the UI elements easier and saves a lot of  
code, but with gwitter i like in principle the two-way binding, converting,  
validating, etc. Any comment or idea?
