GWT DataGrid CheckBoxSelectionModel Issue
Hello Guys! I have an issue with GWT Grid using CheckBoxSelectionModel, my ListStore is loaded by default with all the elements (checkboxes) selected and they are locked because they didn't change by user. So when i click on a column header the sort event deselect all ListStore elements. I've tried a lot of examples like handler the sort event or selectionChangedEvent but i can't find out what i missing. Someone have an idea? P.S: My english is very bad, sorry about that!

Re: CellTable - how to avoid unnecessary onRangeChange events?
Magnus, Hi. I didn't found an easy and simple solution for that. In my application I wrote a DataManager which is an AsyncDataProvider and has some cache functionality. So when I get an onRangeChange event I just go to server when it's really needed, fetching only the missing range. It do a lot of things, but only this class for me is getting 800 lines :( Of course, this cache functionality is smaller than this, but still complex. I haven't tested yet the performance of my code. I could share something with you, if you are interested in. Em quarta-feira, 28 de novembro de 2012 12h43min24s UTC-3, Magnus escreveu: Hi, I found that my CellTable sends unnecessary onRangeChange events in a specific situation: - The data source changes, e. g. the user selects another chat room. - The new row count is less than the old one. Then, when calling the data provider's updateRowCount method the GWT code recognizes that the current range exceeds the row count and corrects the range somhow, triggering an onRangeChange event. Independend of this, the application also as an idea which records to show and also sets the new range. In the end, the page is loaded twice. Can we avoid this?

CellBrowser improvement
Hi, it's my first time writing to this community here, if I say something wrong or in the wrong place, just say it :) I've been working with GWT for half a year and it's really great. But this days I've found a behavior I think it's not the best one. I've a CellBrowser which get all the information with AsyncDataProviders. So if you open a node, it gets new data through RequestFactory/RPC. When I update one object I decided to delete the old one and add a new one. When that happens, at least this object and its childs has to be updated as well. I'd like to automatically select again the leaf that was selected before I've updated the object (E.g. one root object). Ok ... I've created a class to do this, using setChildOpen() and selecting the objects in the selectionModel. But I have to wait the node to be open first and, then, I can have the new object and the select it and, if necessary, open it also. (recursively). I've binded an OpenHandler to the CellBrowser so I could know when that happened. What's the point: when I got an Open Event, it is opened, but its childs are not ready, are not fetched. So I can't do anything at this point. My suggestion: the onOpen event should only be fired when all the data is ready (or at least the page that was requested). If someone could tell me some tips to do what I want, I appreciate. I'm think about creating a Timer that checks if the data are ready, an then select the object and so on. It's not the most elegant solution, but could work. Sorry about my poor english. Rafael Paulino -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: ui:with to set property values (issue1524803)
Exactly, your diagnosis matches my expectation. The thing is we do the
precedence detection when first declaring the widget, making sure
that its at least (parentWidget.getPrecedence() + 1). And you're right
that we don't update it when we see a reference. I think that to make
your scheme bulletproof we'll need to implement that.
BTW, this wasn't a problem until now when a widget references a
ui:with element because we always output all ui:with elements
before any widget, so that precedence doesn't really matter. With your
patch, it will matter.
On Wed, Sep 21, 2011 at 1:25 AM, jus...@jhickman.com wrote:
From what I can tell, the order of the build_X calls are based upon the
order of ui:with declarations in the XML and not alphabetical order.
It also appears that since ui:with are always at the top level (right
under ui:UiBinder root element), they always appear as precedence 1
no matter how they are referenced.
Ignoring ui:with elements for a bit, I have created nested widgets to
see how they behave with the build precedence, and from my tests, the
precedence appears to be directly linked to the level of nesting, even
if I have widgets referencing other widgets (through field reference).
For example, taking the following XML snippet:
g:VerticalPanel ui:field=A
g:SimplePanel ui:field=B
g:SimplePanel ui:field=C /
/g:SimplePanel
g:LazyPanel ui:field=D
m:FooBar refWidget={C} ui:field=E /
/g:LazyPanel
/g:VerticalPanel
(Where FooBar extends Widget and has a setRefWidget(Widget) method).
This is what I see in the generated output:
public Widgets(final UiBinderParserUiWithTest owner) {
this.owner = owner;
build_C(); // more than one getter call detected. Type: DEFAULT,
precedence: 3
}
Then, the precedence is set as follows:
A = precedence 1
B = precedence 2
C = precedence 3
D = precedence 2
E = precedence 3
This is the same output even when the LazyPanel is switched to
SimplePanel or any other container. Also seen here is widget E getting
reference to widget C.
I then added a ui:with element to the mix, without my patch, and see
that the ui:with is still set to precedence 1, even though it is
referenced from a deeply nested child widget:
ui:with type=com.google.gwt.user.client.ui.SimplePanel field=W1
/
g:VerticalPanel ui:field=A
g:SimplePanel ui:field=B
g:SimplePanel ui:field=C
/g:SimplePanel
/g:SimplePanel
g:SimplePanel ui:field=D
m:FooBar refWidget={W1} ui:field=E /
/g:SimplePanel
/g:VerticalPanel
This has a very similar result in generated code, except now the Widgets
constructor does not contain any build_X() calls.
W1 = precedence 1
A = precedence 1
B = precedence 2
C = precedence 3
D = precedence 2
E = precedence 3

From the version of Test I have attached with the patch, it outputs
this:
public Widgets(final
com.google.gwt.uibinder.test.client.UiBinderParserUiWithTest owner) {
this.owner = owner;
build_test1(); // more than one getter call detected. Type:

build_test4(); // no getter call detected but must bind to
ui:field. Type: IMPORTED, precedence: 1
build_test5(); // no getter call detected but must bind to
ui:field. Type: IMPORTED, precedence: 1
}
I'm not sure what you mean by having test1 depend on test3, since the
class for test1 (TestBeanA) does not have a dependency to the class for
test3 (TestBeanB). If you're talking about bean order, I have changed
the order of the ui:with elements such that test3 appears first:
Sorry about the delay to reply, I was flying back home.
See how in the comments it says precedence: 1 for all testX? That
means we're not detecting that test1 needs to be built before test3.
We're just generating the code in some (alphabetical?) order that
happens to work for your dependency tree. I'm pretty sure that if you
play around with the name of the fields, you can get this to break
(i.e., build_Y() is called before build_X(), but Y needs X).
We try to get around this for normal widgets using the buildPrecedence
field in FieldWriter. If you look for uses of setBuildPrecedence
you'll see that FieldManager makes sure that the precedence of a child
is always greater than its parent. This means that when you have
gwt:Panel ui:field=parent
gwt:Label ui:field=child /
/gwt:Panel
child will have a higher buildPrecedence than parent, so in the
generated code build_Child() will be called before build_Parent().
That, in turn, guarantees that build_Parent() can safely refer to
get_Child(). Since in your case, one field isn't the child of
another (in the parsing tree sense), we don't detect this. We need to
figure out another way of figuring that out.
ui:with type=comUiBinderParserUiWithTest.TestBeanB
field=test3
ui:attributes beanA={test1} /
/ui:with
ui:with type=com.UiBinderParserUiWithTest.TestBeanA
field=test1 /
ui:with type=com.UiBinderParserUiWithTest.TestBeanA
field=test2 /
ui:with type=com.UiBinderParserUiWithTest.TestBeanC

/ui:with
ui:with type=com.UiBinderParserUiWithTest.TestBeanC
field=test5
ui:attributes beanA={test1} beanB={test3} /
/ui:with
This changes the content in the Widgets constructor:
public Widgets(final
com.google.gwt.uibinder.test.client.UiBinderParserUiWithTest owner) {
this.owner = owner;
build_test1(); // more than one getter call detected. Type:

build_test2(); // no getter call detected but must bind to
ui:field. Type: IMPORTED, precedence: 1
build_test4(); // no getter call detected but must bind to

}
I have also modified TestBeanA to have a TestBeanB property so that I
may test cyclic dependencies, and it appears to continue to function
with this generated code:

Since the implementation I'm presenting here uses the BeanParser, it
generates code that uses the getter methods when accessing fields
identified with ui:with elements. Here is a sample of what the
generated code looks like for the provided integration test. (I removed
extra line feeds to compactify a little). In it, you can see the
get_testX() methods are called rather than direct field access.
I see that, but you still have to be sure that build_test1() is called
before build_test3(), as the latter calls get_test1(). I don't think
that is guaranteed by the current UiBinder implementation of
dependencies. We tried to detect this by checking the parent field

this case.

[gwt-contrib] Re: ui:with to set property values (issue1524803)
So, let me try to clear up what I'm afraid about in more detail. The
lazy widgets code generation splits attribute creation and access by
creating 2 methods build_XYZ(), and get_XYZ(). All setters are called
in the build_XYZ() part, so you'd have something like this:
private void build_layoutData() {
this.layoutData = GWT.create(LayoutDataType.class); // or
owner.layoutData if it's provided
this.layoutData.setLeft(15);
this.layoutData.setComplexAttribute(get_otherObject());
}
private void build_otherObject() {
this.otherObject = GWT.create(OtherObjectType.class); // or
owner.layoutData if it's provided
this.otherObject.setRight(15);
this.otherObject.setColor(#FFF);
}
private OtherObjectType get_otherObject() {
return this.otherObject;
}
private LayoutDataType get_layoutData() {
return this.layoutData;
}
The only way this can work is if build_otherObject() is called before
build_layoutData(). I don't think there's anything in the code right
now that guarantees this. There is the notion of per-type precedence
and we do look at direct links. That means that we always create
resources before ui:fields, and that we look at some signals to see
which ui:fields should be created before the other, but I'm pretty
sure that logic won't get this new flow.
Makes sense?

In this case, order of ui:with declarations would matter.
You also have to watch out for cyclic dependencies, but that's the same
for any development.
Fortunately, with the way this code was modified, if the nested
ui:attributes is missing, the behavior falls back to original
behavior. More complex object creation should be done in the owner
class.
Could you remind us what the original behavior is? The failure mode needs to
be better than bad code gen. Basically we need unit tests covering the cases
you point out.

Re: History.newItem() not working in IE
Just after posting this message I found the solution! It seems that IE cant find the iframe if it is not the first element of the page. The problem was the script file (LfwMapKeys.js) being included in the HEAD section of the html. I moved it to the BODY section, just after the iframe declaration and now the history in IE is working fine. On 22/08/2011 20:49, Cerávolo wrote: Hi.

This is only happenning in Internet Explorer (tested with IE 8). In FF it works properly.

[gwt-contrib] Re: Provides an integration test for IsRenderable (issue1527804)
Awesome, I like #1 too. I was driving to work this morning and thinking about it: #2 actually encourages bad behavior, because it'll seem it's OK to fiddle with the elements between calling bind and attaching, and it's really not. We _could_ make an effort to make it work, but it's much better to make the flow clearer this way: if you're using lazy widgets, your elements have to be lazy too. On Wed, Aug 17, 2011 at 9:41 AM, Ray Ryan rj...@google.com wrote: I like #1 too. I think we should try to narrow the visibility of PotentialElement as much as we can. So #1 means two things , right? • Widgets are seated in their @UiFields immediately • In an IsRenderable owner, Element and subclasses are only available via LazyDomElement, and @UiField Element is a compile time error I've tweaked the test a bit (will update soon), and I'm happy to report that composites around non-IsRenderables work as expected, with element fields filled immediately. Given that I don't think we need to delay the switch to using lazy widget builder by default.

[RPC problem] Caused by: java.lang.OutOfMemoryError: Java heap space
Hello everyone! I have a very disturbing problem (disturbing to me at least), the exception mentioned in the title of this post occurs on the server side but after the RPC executes. I'll explain briefly, i have a DAO interface and a DAO implementation, and besides, i have the two interfaces and class necessary to implement a GWT RPC, i use the latter to define a way to call the methods of the DAO from the client via a asynchronous call. When i try to invoke the GWT RPC, the method in the DAO executes without incident but before the result can be returned to the client the exception takes place. I am starting tomcat with the -Xms1024M flag in order to increase the heap space but i guess there is some very unefficient memory handling somewhere in there (in my app, not in tomcat nor in GWT) but i need to know where before i can fix it... has this happened to anyone? my guess is that the memmory suffices for handling the RPC but not for serializing... anyway, i decided to seek your advice... thanks in advance!

Re: Error Polymorphic RequestContext GWT 2.4 RC

final private EventBus eventBus = new SimpleEventBus();
private BaseEntityRF rf = GWT.create(BaseEntityRF.class);
@Override
public void onModuleLoad() {
rf.initialize(eventBus);
CountryRequest reqCountry = rf.countryRequest();
CountryProxy country = reqCountry.create(CountryProxy.class);
country.setCode(FR);
country.setName(France);
}
}
@ProxyFor(value = Country.class, locator = BaseEntityLocator.class)
public interface CountryProxy extends BaseEntityProxy {
String getCode();
String getName();
void setCode(String code);
void setName(String name);
}
@Service(value = DAOJPA10.class, locator = DaoServiceLocator.class)
public interface BaseEntityRequestT extends BaseProxy extends
RequestContext {
RequestVoid insert(T instance);

Hi guys, The RequestFactory could be used for comunication between logic tier and presentation tier in desktop like JavaFX, to build data-oriented (CRUD) software where I use GAE to data and logic tier?

Wanted to ask you guys for specific feedback on the fact that I am
changing the phase right before calling the wrapCallback. As I stated
on the comment, I'm doing that because the UiBinder-generated code
calls getElement(), and it must know it doesn't need to trigger the
slow process. I see 2 other options:
- change the wrapCallback to receive an element;
- change the check on getElement to use something other than the phase;
Please let me know if you think either of these is better (that is,
assuming you're happy with the Phase thing at all).
cheers,

Re: google map TileLayerOverlay
Thank you Eric. I plot several TileLayerOverlay in secuence and look like an animation over the map. At init I preload all tiles in the map but I put them setVisible(false). Something like this: TileLayerOverlay tlo = new TileLayerOverlay(tw); mapWidget.addOverlay(tlo); tlo.setVisible(false); So the navigator brings all necesary images. This is like a buffer. But how I don't know when all tiles are really loaded by the navigator I can't know when really start the animation properlly. It can be posible if I could access to the onLoad event of each tile loaded by the api, or maybe if I could acces to the complete property of the img objects. I'm trying to use this property but searching all img objects.

I have to review some other tricky cases (like if you add a non-attachable widget to an Attachable panel before finishing the initialization), but we're pretty close. The other cases that could trigger this is calling some UIObject method that we haven't yet @Override (like we did for setStyleName). Those call getElement() and hurt us.

I'd be totally fine with a RuntimeError, it'll probably be m ore
manageable in the long-term. I was trying to support this because even
though it's less efficient, we can still make it work. The scenario here
is:
1-) Build Attachable tree. This includes calling all the render() stuff
and so on. Let's assume that this particular AttachableHTMLPanel is in
the middle of the tree.
2-) For some reason do something to this particular panel (that's in the
middle of the tree) that calls its getElement() [let's say attach it to
the document]. This triggers the process of building the widget tree as
if this panel was the root (i.e., hidden div, set innerHTML, getting
elements for all children and initializing them). At this point
everything works
3-) Now you go and attach the real root of the tree, an ancestor of
this panel. We can do one of 3 things:
(a) throw an error. You probably didn't mean to do this as it's less
efficient
(b) replace the element that our parent assigned us (along with its
subtree) with the subtree we already built in step 2
(c) re-do everything in step 2, ignoring the fact that we already
initialized all children widget
I think (a) would be ideal, specially for debugging purposes. Honestly I
implemented (b) because I was a little afraid and wanted to be as
backwards-compatible as possible. I don't think (c) would work
out-of-the-box, as we'd have to support initializing Widgets twice
(i.e., re-setting the element, etc.)
Makes sense?

primitive arrays vs Collections (performance wise)
Hello there! I've meaning to ask you the question implied in the subject of this post. Is there an advantage in favoring Arrays over Collections when working with code that will end up in the client (translated to HTML and JavaScript that is)? My gut tells me that i should stick to arrays in order to keep performance on the client side, but i must admit that i do not exactly know what happens with arrays or collections when they go through the GWT compiler and therefore lack f hard evidence to support such a bold statement... Anyway, i was wandering if anyone else had thought of this... thanks in advance! take care!

for(int i = 0; i getWidgetData().length; i++)
suggestions.add(getWidgetData()[i]);
oracle.addAll(suggestions); - NULL POINTER EXCEPTION

from the following method (method that belongs to the class

// Formatted suggestions should already have normalized

return formattedSuggestion;

solution, so any help will be most welcome and appreciated!

Once I started doing this, I stopped using GWTTestCase altogether. I unit test all my UI logic with just JUnit and EasyMock. My tests (500+) finish in about 20 s.

Date Picker not found in GWT 1.7.1
Hi, I'm trying to use the datebox after GWT upgraded to version 1.7.1, and noticed that the screens that have this component does not work.

Re: How to download a file in IE8?
alex.d,
I am having same problem but with a csv file. I think it's that IE8
fails to recoginize the type (MIME type) of the file, so it reloads
the page rather than ask the user to save as...
I asked same question in another post. please ignore.
Surprisingly, i can server the file to IE8 in Vista just fine. But not
for IE* in XP.

Inheriting a css stylesheet
Howdy? I've written a small module with custom widgets and a simple CSS stylesheet. The problem is that when i inherit the module, i inherit the client side code but not the stylesheet. I am sure this is caused by some silly mistake (judging by the docs i read) but i still cant identify what i am doing wrong. Thanks in advance!

GWT Application aspects
¡Hello everyone! I am trying to set up an initial skeleton for an application. In order to achieve this i considered every aspect (not EVERY ONE of them, of course) of the application i'd like to handle and reached the following decision: Views, presentation, etc: GWT (or else it would not be on this list now would it? :P) Data access layer: Spring/Hibernate/postgreSQL client side validation: GWT-Validation Flow: Not yet decided if i am going to use Spring Web Flow or plain old GWT Deployment environment: Tomcat 5.5 or later I thought about creating a second GWT Module to store my custom widgets What i'd like to ask you people is the following: 1)I've seen a couple of posts about Spring Web Flow but neither are simple enough for me to comprehend, has any of you had a pleasant experience integrating GWT and Spring Web Flow? if not, how do you implement flow control within screens, pages, etc 2)I am a bit confused about how i should organize my application (considering i just made the leap to web 2.0). For example, i used to split every application into several modules (LoginModule, ClientModule, SalesModule, etc) so every module could contain the services related to them. I guess that such modules should only exist on the server side adjusting to their role of service providers right? nevertheless, i thought they should have some kind of client counterpart in order to be able to access their services in a organized way, is this correct? 3)Most important, did i say something terribly wrong at the beginning of this mail? (you know, like, oh my god, this guy does not know what he is talking about kinda wrong) I think of GWT as a source of great power, however, i do not seem able to harness such power yet...

Re: GWT and Hibernate XML files vs Annotations
It is off topic, right? I was suspecting that...
The thing is that being a newbie, it is difficult for me to tell when
Hibernate ends and GWT begins. Looking around i realized that annotations
are just a great Hibernate feature and all questions regarding that matter
should be directed to the propper groups but i had already sent the
distress call when i found out hehe
Whenever a Spring or Hibernate issue arises i ask myself is this a
Hibernate or Spring issue? or is a Hiberante or Spring being used with GWT
issue? thats another reason why i used this group for my post.
Anyway, its working, so thanks a million!
Will be more careful with the off-topicness from now on ;)
2009/5/28 eggsy jimbob...@hotmail.com
Hi Rafael,
Its somewhat off the topic of GWT but the inheritance you wish to map
is not a problem with Hibernate annotations.
Using an example the class HumanResource below inherits from the
Resource class:
@Entity
@Table(name = resource)
@Inheritance(strategy = InheritanceType.JOINED)
public class ResourcePOJO implements Serializable
{
Your annotated getters and setters
}
@Entity
@Table(name=human_resource)
@Inheritance(strategy = InheritanceType.JOINED)
@PrimaryKeyJoinColumn(name=resource_id)
public class HumanResourcePOJO extends ResourcePOJO implements
Serializable
{
Your annotated getters and setters
}
Notice the inheritance annotation and the PrimaryKeyJoinColumn
annotation.

Hi Rafel,
Yeah you can do everything in Hibernate Annotations its really quite

Re: Official libraries

Go to code.google.com and search on gwt.
You'll find a metric whackload of results. There's also a list in the
regular GWT docs of third-party-extensions; many of them are quite
powerful.
If you want to maintain consistency with future versions of gwt, I
recommend that you do not stray too far from the beaten path... There
are whole frameworks like Rocket GWT or Gwt-Ext that try to emulate
prototype or other JS libraries, but these are kind of like
downloading proprietary drivers in Linux... They'll work, but when
things get updated, you will have to wait until someone else feels
like updating and releasing a new binary before you can catch up with
the times.
I'd say, grab the gwt-incubator, as that's actually the gwt dev teams
prerelease stuff {StyleInjector deprecated a LOT of hackery I wrote
myself, thank God!}, and maybe look at GwtQuery {written by Ray
Cromwell, the Timelord of GWT}, Gwt-log, and Gwt-dnd, as these are all
maintained on code.google.com, and seem to stay up to date.
Besides that, just google gwt + whatever-type-of-task-you-want-to-do
like, gwt drag n drop or gwt audio and you'll get lists of results
to peruse.
GOOD LUCK!

Gilead tutorial
Howdy! I was wondering if anyone knew of a tutorial and/or introduction for Gilead, the reason i am asking you for this is that i read the official tutorial and i was not able to follow it completely (i should point that i can be considered a total nooboid in what regards GWT and related technologies, hibernate also) Speaking of nooboids, i was wandering if, instead of using Gilead, i could do the following... Consider i have a functional Hibernate project, i could extract the POJOs from the project and make them visible for the client side of a GWT application and perform all the heavy duty database work in async services, right? I guess that where i am going with this is that i am failing to see the goal of GILEAD, the reason it was created, the problems it aims to solve (although i am sure there are, i do not mean any disrespect to the Gilead project) thanks in advance yours trully Rafael Barrera Oro PS: If what i just said is so wrong that it hurted your front lobes please refrain from coming to my castle angrily waving pitchforks and torches around, just point it out in a respectful manner i will listen thankfully and bow my head in gratitude --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Using previously existing project on the client side
Hello, i just wanted to make sure that i got it right... If i have an existing project, which has its own dependencies, and i want to use it on my GWT application, on the client side, ¿i have to package the mentioned project and then get the source packages for all its dependencies? (considering they are all 5.0 compatible) The problem is i have an ORM generator which generates a set of classes which i would like to use on the client side, but they are a little more than POJOS, thats why they have their own dependencies and i have not been able to use them so far (on the client side, of course).

How do you design your project structure?
I was thinking of a way to structure my projects, mostly how to distribute the file, when it thought of consulting you about the matter. This is how i structured my project ar.com.company.public (html, css, etc) ar.com.comapny.public.images (this i created specially for images) ar.com.company.client (Java clases) i creatad the following packages for services: ar.com.company.server.services ar.com.company.client.services I am facing now the need of creating packages to hold the Java classes related to widgets of my own creation, so i wanted to consult you first on which are the best practices to structure a GWT project as it begins to grow ¡Thanks in advance! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Style Names
To be honest i do not have much experience with .css. The thing is, i am getting confused when trying to set the style of a widget. I understand i should use the method setStyleName() or addStyleName () but i dont know where to look for possible style names. For example: final DecoratedStackPanel stackPanel; //creo el stackPanel stackPanel = new DecoratedStackPanel(); stackPanel.setStyleName(DecoratedStackPanel.DEFAULT_STYLENAME); Instead of DecoratedStackPanel.DEFAULT_STYLENAME, ¿Which other style names could i use? ¿Where could i find a list of basic built in styles? the nooboid (Rafael) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Necessary .class files in order to deploy a GWT application
¡Hello People! I was following the instructions to deploy a GWT app on a Tomcat server (http://code.google.com/intl/es-ES/docreader/#p=google-web- toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=DevGuideRPCDeployment) and it ocurred to me that the only .class files that should be copied onto the WEB-INF/classes folder are the ones located in the package package.module.server, considering that the remaining classes (the ones located in the public and client packages) are compiled via the GWT compiler into html, css, etc. ¿Is this correct? I should warn you that i have little to none experience with GWT so i am perfectly capable of not making any sense ¡Thanks in advance!

That did it.
Another question for you...I am now getting OutOfMemoryErrors while
trying to compile and build Google Web Toolkit from Maven. I tried
setting my pom file to:
plugin
groupIdcom.totsp.gwt/groupId
artifactIdmaven-googlewebtoolkit2-plugin/
artifactId
configuration
forktrue/fork
logLevelINFO/logLevel
runTargetcom.baesystems.grading.gwt/Main.html/runTarget
compileTargets

/compileTargets
gwtVersion${gwtVersion}/gwtVersion
/configuration
executions
execution
goals
goalmergewebxml/goal
goalcompile/goal
/goals
/execution
/executions
/plugin
But there's no process fork going on. I also tried setting
jvmArg-Xmx1024m/jvmArg but that doesn't help either.
Has anyone come across this?
Thanks.

Hi,
I am using jboss, eclipse and ant (not maven) to deploy my web
application
using GWT 1.5 and no problem at all. Check your html host page. A simple
check is trying to download the nocache file as is written in your
webpage.
If it can be found by the browser well at least your web application is
well configured.

Hi all,
I'm using Eclipse Maven to deploy a GWT 1.5 web application to
JBoss. When I run the application inside of the built in Application-
shell.cmd program, I see my web application inside of the Google
Browser Window.
However, when I build the war file using Maven and the GWT Archetype,
I am unable to visit the web application home page.
Maven runs and bundles the outputs of the Application-compile.cmd
file. This includes a WEB-INF complete with classes and lib folders
along with the nocache and cache html and js files.
Was anyone else ever able to deploy and view the outputs of a GWT
application successfully?- Hide quoted text -

Re: Best practices
Hello Gregor, Have you thought in put your answer in a BLOG? For me your message is an GWT optimization article.
