Re: Open a local file with GWT
HI,
i am new to GWT, I have similar query. I want to open a file which is
place somewhere in server file system (i.e. a directory on server
contains some directory and files in it). I have to represent it in
tree structure and display the file on click of leaf Node.
I am paused at opening a file on click event. I want to open it in a
widget ( every time a new leaf node click on tree a file would be
opened opened in same window/widget replacing the old one).
could any one tell me what approach i should follow?
any link or suggestions are appreciated.
thanks in advance.

tab on firefox or I Explorer or Chrome wirks without a problem.
Maybe another solution is not to call a rpc to download thefileand
instead of that make something like an old servlet that make a call to
download browser. I've trying this thing works since a lot of time and
I still didn't find a solution.
I hope someone could help me with this,

O.K.
1) what is pdfLink? is that supposed to be link?
2) if you have any kind of Popup blocker, attempting toopena window
from the callback will fail. if you want toopena window, it has to
happen as a direct result of a user action (onClick, etc)
3) if link is a path to a filesystemfileare you sure it is correct?
(this is sneaky, but just might work)
4) Technically not causing a problem but, use generics.

Deferred Bind on Login to load different user interface
Hi everyone, Been checking out alot of the deferred binding tutorials that seem to involve reading from the meta data in the html before loading the appropiate module. If i wanted to load a deferred binding class after a user logs in (eg. after the user logs in load the same app with a different skin and interface) Would this involve something like using JSNI to change the meta in the html after a user logs in and forcing a refresh? Or is there a better approach to doing this. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

At the moment I'm already doing that. The application is organized
that way, that I have a tree on the left side, that creates a widget
in dependence of the entry being clicked (using the code I posted
before), so until somebody clicked on something, I can be sure
that there is no reference in the system to a particular widget.
Before I place the newly created widget I remove the widget that
has been placed before using the following code:
IMainPanel panel = (IMainPanel) horizontalSplitPanel.getRightWidget();
if (panel != null){
panel.shutdown();
horizontalSplitPanel.remove((Widget) panel);
}
Should I call panel.removeFromParent() explicitly in addition to
calling remove or is this happening automatically in
horizontalSplitPanel?
Is your mobile app the same as the desktop version or are there
dedicated mobile views?
There is no mobile version of that application and the application
is simply too big and complex to do that. It's not too much of a
problem because there was no initial plan to target this application
for mobile devices (it's the administrative backend I was speaking
about already on this list with ca. 1MB of compiled code).
I was just curious in the beginning to see this app running on
the iPhone and the Android device I currently have my hands on
and was positively surprised that more or less everything works
(at least on the iPhone, the Android system even can't login
using Basic Authentication) until the point the application
crashed. So if there are steps I can do to enable this already
existing application on an iPhone this would be a quite cool
thing to show e.g. on workshops with customers but it's nothing
sale-numbers are dependent on it.
I'd probably suggest to make a separate GWT

the common parts, and inherit them in the mobile version .
This would effectively double the amount of work for - in this

Re: Large GWT-application on mobile phones
It should work on the phones without creating a seperate app. After all,
that's the whole point of putting actual browsers on the phones (iPhone is
running the desktop version of Safari with some multitouch enhancements).
Have you tried running it under desktop Safari? Also, try upgrading to 1.5
or 1.6 (1.5 should have less chance of breaking things but 1.6 has
performance stability improvements I believe).
Have you performed the steps I recommended for tracking down the cause using
the server-side code?
Also, different browsers do have different behaviours, so if you've never
tested your app on Safari on the desktop, I would seriously recommend
starting there as it uses a completely different rendering engine (Webkit
which is also what Android uses).

Re: I just realized that dependency injection is possible with GWT
Actually, I'd be surprised if the dependancy injection implementation doesn't boil down to a form of deferred binding in the end for performance reasons (except using the Generators mechanism instead of explicit deferred binding).

Yes, that's not dependency injection, it's just deferred binding. This is not *injecting* anything, you still have to instantiate your class explicitly with a GWT.create(...) call somewhere in your code (you don't say at that point which specific implementation will be used, but that has nothing to do with dependencies nor injection). If one of your classes gains a dependency on another interface, you'll have to inject that new dependency at each and every instantiation point. In summary: deferred binding has nothing to do with dependency injection. Deferred binding is very handy, but it's just something else (and a DI framework for GWT *must* IMO support deferred bindings, but all of them, from Suco to GIN, support it AFAICT). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: File Upload with rpc call
No, not with native Javascript. You have to have the user do it manually upload the parts - the rejoining can be done automatically on the server. One way would be through the use of multi-part archives. Or use the flash-based approaches that seem to be popular. http://mike.kruckenberg.com/archives/2008/02/inline-web-browser-file-upload.html, although even they may not give you what you want. Web browsers were never really meant for uploading large amounts of data to servers but instead to go the other way.

Re: GWT 1.6 with Maven and build system questions/survey...
Hi I was using a maven plugin (http://gwt-maven.googlecode.com/svn/trunk/ mavenrepo) with GWT 1.5.3 without Hosted Mode (in Linux the hosted mode gives a firefox browser older and doesn't support gears, for example), I generate a war and the copy it to a jboss server to test it. I know that it is not very useful, but it is the problem for linux users :( But when I try upgrade to GWT 1.6 it doesn't work: crash in the test task. If anybody has the same problem, please contact with me. thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: File Upload with rpc call
by this method, if file size is large, it may take very long time or even fail if network is slow. can't we break file into smaller parts before sending and send one-by-one and then rejoin it at server?

Re: I just realized that dependency injection is possible with GWT
On 10 avr, 17:52, Yves yves.cuillerd...@gmail.com wrote: Hello Reading the documentation for the module xml files, i just realize that the tag replace-with .../ allows for dependency injection. How that?! Suppose i need to use different class implementation depending on my environment (real class for production, mock for development ...).

Yes, that's not dependency injection, it's just deferred binding. This is not *injecting* anything, you still have to instantiate your class explicitly with a GWT.create(...) call somewhere in your code (you don't say at that point which specific implementation will be used, but that has nothing to do with dependencies nor injection). If one of your classes gains a dependency on another interface, you'll have to inject that new dependency at each and every instantiation point. In summary: deferred binding has nothing to do with dependency injection. Deferred binding is very handy, but it's just something else (and a DI framework for GWT *must* IMO support deferred bindings, but all of them, from Suco to GIN, support it AFAICT). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: I just realized that dependency injection is possible with GWT
On 14 avr, 11:42, Vitali Lovich vlov...@gmail.com wrote:
Actually, I'd be surprised if the dependancy injection implementation
doesn't boil down to a form of deferred binding in the end for performance
reasons (except using the Generators mechanism instead of explicit deferred
binding).
That's not what Suco does, for instance, as it's entirely client
side:
http://code.google.com/p/suco/
But as I said, that a DI framework work smoothly *on top of* deferred
binding is a must-have (or should-have), but deferred binding has in
essence nothing to do with either dependency management or any kind of
injection, only with, well, deferring the type binding (which
concrete class to use as an implementation of a given abstract class
or interface, or which specialized class, if any, to use for a given
concrete class) to compile time [*] rather than coding time.
I admit that there are crossing concerns between DI and deferred
binding (namely, code against an interface, no matter which concrete
implementation you'll actually be running against), but DI has much
more: it's all about removing all explicit class instantiations from
your code (which also means removing scope management (singleton,
etc.) from your code), while deferred binding is only about choosing
the class that will actually be instantiated.
A key difference is that dependencies with deferred binding have to be
part of the interface you're coding against (be it an interface,
abstract class or concrete class; I'm using interface here as meaning
contract), and you still have to inject dependencies by hand. With
DI, an interface/contract provides some service, and the DI
framework will inject dependencies based on the actual class being
used.
Actually, deferred binding is only a kind of optimization to avoid
code à la switch(GWT.getBrowser()) { case IE: ... break; case
Mozilla: ...; break; etc.
It's a wonderful tool, but it's just not dependency injection.
My opinion is that you should use deferred binding to have different
code paths depending on some runtime property (or eventually compile-
time: in GWT-in-the-AIR, you choose at compile time whether you
compile for AIR or browsers, and this has an impact on some deferred
bindings, such as FormPanel, and of course AIR.isRuntime(), which is
pretty similar to GWT.isScript() or GWT.isClient()), and use a DI
framework (my vote goes to GIN, but that's a personal taste)
otherwise, such as for a testing environment; but of course, YMMV.
[*] or you could say runtime, if you're generating multiple
permutations, though everything's done at compile time, and at runtime
bootstrap code only choose between already compiled bindings.

Re: Put GWT 1.6 Application Online
When you run in hosted mode, there's nothing preventing other people from connecting if you have first compiled the code (without it, they would need some way of communicating to the code running within the Java VM). It should be automatic (works for me anyways). Generally though, people prefer, from what I gather, of deploying to a dedicated app server because they tend to have more control over the configuration.

Re: [GEP] Unknown argument: -server
Hi Sumit, 1) This does prevent me from running hosted mode. The error actually appears in the Console view, not as a popup. It's as if I'd typed javaw com.google.gwt.dev.GWTShell -server at a command prompt. The launch is terminated at that point. 2) This project started as GWT + GAE/Python (GAEP?). I decided to toss the Python backend and try to set up the project as GWT + GAE/Java using the new plugin. I haven't even added any servlets I added gwtNature and gaeNature, set GWT to the 1.6 SDK, removed my old GWT 1.6 milestone build from the classpath, then tried to run hosted mode. Because I don't have war/web-inf/web.xml, it runs GWTShell instead of HostedMode. It sounds like the problem is that the plugin doesn't expect this state and ends up passing invalid parameters to the old GWTShell. Results of further experimentation this morning: I tried to make it run HostedMode instead of GWTShell by removing gwtNature (I removed gaeNature as well, just because), adding war/web-inf/web.xml, and re-adding the natures. This did get HostedMode to run. Then I reversed the operation in an attempt to get the old error back. I removed the natures, removed the web.xml, changed the output path back to /bin, and re-added the natures. But it still tries to run HostedMode and complains that it can't find web.xml. It seems like, as long as the old GWTShell is going to be supported at all, there should be an option to explicitly switch between them. Or at least make the decision points more transparent, and reversible. I'd be happy to take a look at the plugin source and see if I can find the error. And if you can't get a reduced test case to reproduce it, you could always zip up the whole project and send it to me. ;) - Isaac On Mon, Apr 13, 2009 at 5:25 PM, Sumit Chandel sumitchan...@google.com wrote: Hi Isaac, You've come to the right place for GWT Eclipse plug-in support!

Or are you able to run it while having the warning message displayed as you use hosted mode? 2) What type of application are you running? (GWT or GWT + GAE) The fact that it's complaining about a -server argument tells me that this is a project configured with the AppEngine nature, but the fact that GWTShell is being used tells me that it's using GWT 1.5, which according to how the plug-in was designed, should be impossible unless there's a bug on our end.

Re: Regarding an Uncaught Exception Displaying
Hiii,
Thanks for your reply,
Fusioncharts are widgets which are working with Flash.
FusionCharts is a flash charting component that can be used to render
data-driven animated charts. Made in Adobe Flash 8 (formerly Macromedia
Flash),
My application is like that,initially when the page is loaded a fusion chart
is loaded along with that.Now if i clicked on the fusion chart bar another
chart is getting loaded.If i clicked the second one,third fusion chart is
loaded. So this is in a drill down manner.
That means fusion charts are working fine.
Now i am going to load the second page and the fusion chart is loaded
perfectly.Now i am going to click the fusion chart for the drill down chart.
But it is going to blank page where nothing is viewed even the grid in the
page..
Now again i tried to restart my application and loaded the page which
caused problem previously,it will work fine,But the other page which was
working fine had gone to a blank page as i said early.
This is happening only in gogle hosted mode and IE.Its working fine in
Mozilla firefox.
I am calling the fusion chart in GWT in below manner.
*public static Panel createRequestFusionChart(MapString,UrlParam
urlsParam,int chartWidth, int chartHigh) {
Panel chartPanel = new Panel();
final Panel fusionPanel1 = new Panel();
chartPanel.setWidth(chartWidth);
final MapString, Object parameters = new HashMapString,
Object();
IteratorUrlParam params = urlsParam.values().iterator();
UrlParam urlParam;
while(params.hasNext())
{
urlParam = params.next();
parameters.put(urlParam.getName(), urlParam.getValue());
}
ParametersProvider parmParametersProvider = new ParametersProvider()
{
public MapString, Object getParameters() {
//Map parameters = new HashMap();
parameters.put(userid, 0);
parameters.put(charttype, 1);
parameters.put(chartmethod, Request);
parameters.put(dept, 19);
parameters.put(link, 1);
return parameters ;
}
} ;
String chartName = StackedColumn3D;
String chartUrl = GWT.getModuleBaseURL() + FusionCharts/ +
chartName + .swf;
String dataUrl = GWT.getModuleBaseURL() + ChartServletNew;
FusionChart fusionChart = new FusionChart(chartUrl, 450, 400,
dataUrl, parmParametersProvider) ;
fusionPanel1.add(fusionChart);
final Panel firstRowPanel = new Panel(Requests);
firstRowPanel.setLayout(new HorizontalLayout(30));
ParametersProvider parmParametersProvider1 = new
ParametersProvider() {
public MapString, Object getParameters() {
//Map parameters = new HashMap();
parameters.put(userid, 0);
parameters.put(charttype, 1);
parameters.put(chartmethod, emptychart);
return parameters ;
}
} ;
chartName = StackedBar3D;
chartUrl = GWT.getModuleBaseURL() + FusionCharts/ + chartName +
.swf?ChartNoDataText=Click left chart to view Services Details;
dataUrl = GWT.getModuleBaseURL() + ChartServletNew;
fusionChart = new FusionChart(chartUrl, 450, 550, Human Resources
(Development)ServDetails, dataUrl, parmParametersProvider1) ;
final Panel fusionPanel2 = new Panel();
fusionPanel2.add(fusionChart);
firstRowPanel.add(fusionPanel1);
firstRowPanel.add(fusionPanel2);
ParametersProvider parmParametersProviderSubServ = new
ParametersProvider() {
public MapString, Object getParameters() {
//Map parameters = new HashMap();
parameters.put(userid, 0);
parameters.put(charttype, 1);
parameters.put(chartmethod, emptychart);
return parameters ;
}
} ;
chartName = StackedBar3D;
chartUrl = GWT.getModuleBaseURL() + FusionCharts/ + chartName +
.swf?ChartNoDataText=Click Services chart to view subservices details;
dataUrl = GWT.getModuleBaseURL() + ChartServletNew;
fusionChart = new FusionChart(chartUrl, 450, 500, Human Resources

final Panel secondeRowPanel = new Panel(Subservices Chart);
secondeRowPanel.add(fusionChart);
chartPanel.add(firstRowPanel);
chartPanel.add(secondeRowPanel);
return chartPanel;
}
*
Here *ChartServletNew* is a Servlet which is used to create the xml of
fusion chart. Inside this *ChartServletNew *there is a link attrubute in
which will call a javascript function which in turn will call the Servlet
again.
This is done in this manner

public void execute() {
Window.alert(test);
}
};
MenuBar start = new MenuBar(true);
start.addItem(Startseite, cmd);
MenuBar ueberBint = new MenuBar(true);
ueberBint.addItem(Unternehmen, true, cmd);

Compiling with the new eclipse plugin, classpaths and generate-with/
Hi, Either I'm doing something wrong, or there is something wrong with the way the eclipse plugin hands out classpaths to the gwt Compiler. The Compiler loads the Generator class from generate-with name= rules when parsing the .gwt.xml files, but it is not passed the war/WEB-INF/ classes (aka, eclipse output) directory on it's classpath, resulting in a ClassNotFoundException when you hit the compile button. Create new Web Application (using the GWT SDK 1.6), name: plugintest, package: plugintest Create (empty) interface plugintest.client.Foo Create (empty) class plugintest.client.FooGenerator Edit plugintest.Plugintest.gwt.xml, add: generate-with class=plugintest.client.FooGenerator when-type-assignable class=plugintest.client.Foo/ /generate-with When you hit the GWT Compile Project button, the error you get is: Loading module 'plugintest.Plugintest' [ERROR] Unable to load class 'plugintest.client.FooGenerator' java.lang.ClassNotFoundException: plugintest.client.FooGenerator ... instead of the expected exception that FooGenerator doesn't extend the Generator base class. Compiling manuall with java -cp %GWT_HOME%/gwt-user.jar;%GWT_HOME%/gwt-dev-windws.jar;src;war \WEB-INF\classes com.google.gwt.dev.Compiler plugintest.plugintest gives the same result. Note that the gwtc target in a build.xml generated by the webAppCreator does include the compiled classes in the classpath of the Compiler. It can be circumvented by adding war/WEB-INF/classes as a source folder or something, but that's obviously not intended. Is this a bug in the plugin, or is there a proper solution (and why is that not default) ?

Re: Deferred Bind on Login to load different user interface
On Apr 14, 9:09 am, matttai matt...@hotmail.com wrote: Hi everyone, Been checking out alot of the deferred binding tutorials that seem to involve reading from the meta data in the html before loading the appropiate module. If i wanted to load a deferred binding class after a user logs in (eg. after the user logs in load the same app with a different skin and interface) Would this involve something like using JSNI to change the meta in the html after a user logs in and forcing a refresh? Or is there a better approach to doing this. Deferred binding is a feature of the GWT compiler that works by generating many versions of code at compile time, only one of which needs to be loaded by a particular client during bootstrapping at runtime. -- http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideDeferredBinding If you use deferred binding for skin support (which might not be a bad idea, depending on the amount of skins and the amount of code they generate), you will need to reload the application to get a different compiler permutation. This includes reloading the HTML, since you'll need to run the GWT bootstrapping code again, which selects the correct permutation depending on the set properties, using something like property-provider name=skin.../ Gert --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

DateBox and onValueChange in GWT 1.6
Hi
I'am working with the DateBox component: show a calendar when you
click on a box. But I have a problem: the listener onValueChange
doesn't work like in the componente DatePicker. This is my code:
DateBox dateBox = new DateBox();
/*dateBox.setFormat(new DateBox.DefaultFormat
(DateTimeFormat.getFormat
(MMM dd, HH:mm aaa)));*/
dateBox.addValueChangeHandler(new ValueChangeHandlerDate() {
public void onValueChange(ValueChangeEventDate event) {
Window.alert(onValueChange datebox);
/*Date date = dateBox.getValue();
try
{
String dateString =
DateTimeFormat.getMediumDateFormat
().format(date);
okButtton.setEnabled(true);
Window.alert(okbutton a true);
}
catch (Exception e)
{
Window.alert(okbutton a false);
Window.alert(e.getMessage());
okButtton.setEnabled(false);
}*/
}
});
This code in DatePicker works. Anybody knows why? Maybe it is a bug of
this componente?
thanks to all

GWT Serialization with CustomFieldSerializer fails because of SerializationPolicy
For data transport we use a simple java class containing a MapString, Object This map is transient and we serialize it with a custom field serializer. This works fine for most situations. For every service gwt has a list of classes which can be Serialized (whitelist). If my understanding is right this list is generated by the compiler at compile time by analizing the members of a class. But we can have classes (which ARE serializable) inside our transient map, but gwt will not serialize this classes because of the SerializationPolicy (these classes could not be found by the compiler at compile time). Is there any way to extend the white list of SerializationPolicy.java ? If I add all classes as private members to my class the members are found and the class can be serialized, but this is anoying and we cant do this for all classes (we dynamically decide which classes we need to transfer) Anyone got any expierence with that?

There may be some Java RPC stuff that will do this for you, if you have Java available on the server. If your server is Apache based and allows Index (or the equivilent for another server technology), then you could parse the HTML output from a CGI get of the requisite directory. Otherwise, you'll need a server-side process to accept a file name request, perform the file lookup and return the results to your client.

Re: ImageBundle too wide to display in IE7 under Vista
Like I said in my original, the workaround was to break up the ImageBundle and that worked. I played around with it and as soon as it went over 2048 pixels, the ImageBundle would not show.

Re: Possible bugs in generated JavaScript Code (GWT 1.4.60)
QUESTION: Is it possible to define a file for 'unknwon' useragents?
It is possible for the GWT compiler to generate another permutation of your
application for additional user agents, but they would have to be known. You
can do this via a property provider. But first, I'm wondering which browsers
your clients are using such that the user agent couldn't be resolved.
Hi Summit
Well, he was using a Firefox with a lot of plug-ins, some of them
might change the User-Agent string.
I do not expect, that the application will work with this browser, but
I assumed
that he will get a nice error message, if the browser is not
supported.
GWT generates a
try {
unflattenKeylistIntoAnswers(['default', 'gecko1_8'],
'278A6CEE55E17277BC30FF22BE7EC49F');
strongName = answers[computePropValue('locale')][computePropValue
('user.agent')];
}
catch (e) {
return;
}
which results in an empty page.Is there a way to provide a nice error
message to the user without changing the generated JavaScript code?
This is the first time I've heard of this problem. I think this could be
related to the browser that your clients are using. I'm wondering if it's in
the list of GWT supported browsers.
As I said, this is not really reproducible. Yes, the browser(s) are on
the list of supported browsers.
Case 1:
They tried Firefox and IE 6 on Windows. Didn't work, they got an empty
page. Rebooting the client
machine fixed the problem. So, no blame on GWT here, but I'm trying to
understand what happens..
Case 2: Different versions of Firefox and IE on Windows. Some of them
worked, some not. Without
rebooting the client machine, I added $doc.location.href += '#'; on
the server side and all browsers
worked fine.
I'm not sure what happend here, maybe both cases are cache problem on
the client side.
Greetings
Mirko

My code is:
JSONArray items = response.get(o).isArray();
for (int i = 0; i items.size(); i++) {
JSONObject item = items.get(i).isObject();
String id = ((JSONString) item.get(id)).stringValue();
String url = ((JSONString) item.get(url)).stringValue();
String ope = ((JSONString) item.get(ope)).stringValue();
String caption = ((JSONString) item.get(caption)).stringValue();
MenuBar opcion = new MenuBar(true);
opcion.setAnimationEnabled(true);
menu.addItem(new MenuItem(caption,opcion));
JSONArray opciones = item.get(opc).isArray();
for (int j = 0; j opciones.size(); j++) {
JSONObject opcion2 = opciones.get(j).isObject();
final String caption2 = ((JSONString) opcion2.get
(caption)).stringValue();
Command menuCommand = new Command() {
public void execute() {
doSomething(id, url, ope);
}
};
opcion.addItem(caption2,menuCommand);
}
}

hosted mode using seperate module for server side code

Re: [GEP] Unknown argument: -server
Hi Isaac, There is a bug here. The launch configuration should not add -server if the project uses App Engine and GWT, but does have the WAR layout. For now, projects in the WAR layouthttp://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6that use GWT 1.6 or later are run under HostedMode. All others are run using GWTShell. Perhaps if you are using -noserver then we should pick from the latest available since there are no servlets to be loaded, etc. On Tue, Apr 14, 2009 at 8:37 AM, Isaac Truett itru...@gmail.com wrote: Hi Sumit, 1) This does prevent me from running hosted mode. The error actually appears in the Console view, not as a popup. It's as if I'd typed javaw com.google.gwt.dev.GWTShell -server at a command prompt. The launch is terminated at that point. 2) This project started as GWT + GAE/Python (GAEP?). I decided to toss the Python backend and try to set up the project as GWT + GAE/Java using the new plugin. I haven't even added any servlets I added gwtNature and gaeNature, set GWT to the 1.6 SDK, removed my old GWT 1.6 milestone build from the classpath, then tried to run hosted mode. Because I don't have war/web-inf/web.xml, it runs GWTShell instead of HostedMode. It sounds like the problem is that the plugin doesn't expect this state and ends up passing invalid parameters to the old GWTShell. Results of further experimentation this morning: I tried to make it run HostedMode instead of GWTShell by removing gwtNature (I removed gaeNature as well, just because), adding war/web-inf/web.xml, and re-adding the natures. This did get HostedMode to run. Then I reversed the operation in an attempt to get the old error back. I removed the natures, removed the web.xml, changed the output path back to /bin, and re-added the natures. But it still tries to run HostedMode and complains that it can't find web.xml. It seems like, as long as the old GWTShell is going to be supported at all, there should be an option to explicitly switch between them. Or at least make the decision points more transparent, and reversible. I'd be happy to take a look at the plugin source and see if I can find the error. And if you can't get a reduced test case to reproduce it, you could always zip up the whole project and send it to me. ;) - Isaac On Mon, Apr 13, 2009 at 5:25 PM, Sumit Chandel sumitchan...@google.com wrote: Hi Isaac, You've come to the right place for GWT Eclipse plug-in support!

Bobby On Apr 13, 5:37 pm, Sumit Chandel sumitchan...@google.com wrote: Hi Bobby, Please check out replies inlined below: 1. I couldn't find a GData Library for GWT, did i miss it (i already checked with the GData group)? I know GData has the Java API, but that (probably) won't compile to JavaScript. However, GData also has a JS API (the JS docs are here http://code.google.com/apis/gdata/jsdoc/1.8/index.html), so at a minimum we could wrap the JS API in a very thin GWT library - i'm wondering if this already exists or if it's planned as an addition to the list of GWT Google API Libraries (http://code.google.com/ webtoolkit/googleapilibraries.html). There currently aren't any plans to provide GData bindings in the GALGWT project, but as you may know, the project is open source and we would welcome any contributions if you were planning on creating bindings for the GData JS library. 2. In the scenario where you have an existing JS library that you want to make use of in GWT, what's the best, thinnest, way to to create a Java wrapper to the JS library? For example, we could create a Java class per JS class. The Java class could keep a reference to the native JSObject, and define the same properties and methods that the JS class provides but which delegate to the JS implementation via JSNI. The problem with this is that after compiling to JS, we end up with a JS wrapper around a JS object. Is there a better implementation approach that will avoid this? I think the easiest way to wrap the objects in the GData JS library is to not actually wrap them, but overlay them with JavaScript Overlay Types (link below). This is the technique that is used for the existing Google APIs that have bindings in the GALGWT project and would be the easiest and best way to provide support for GData bindings as well. The greatest thing about the overlay technique is that there is zero overhead to pay for overlaying the JS object. The one-to-one nature of the binding also makes it somewhat intuitive for developers to follow documentation on the proper API as they use it in their GWT project through GALGWT, so there's yet another win by choosing the overlay strategy.

Problems with ImageBundle in IE8 when not in compatibility mode
Greetings, Only in IE8 with compatibility mode off do I see the images in the ImageBundle displayed in the right location but other images from the bundle are displayed to the left of the displayed image. In other words it isn't clipping the bundle to the left. In compatibility mode it works fine and it works in IE7, FF3, Opera, and Safari. This a problem in 1.6.4 and 1.5.3. I've looked for previous discussions of this and found http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/e992a62fedc9e974 where Janie says I'm trying to track down an issue with ImageBundles that I'm having in IE8.

Load gwt module before image are loaded on IE7
Hi, I have a page that contains a lot of images and some of those images take a long time to load (in total like 1 min) I have searched the forum and found this similar post http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/d0f0f71ebfd74f0/ff7cc59bd0cb3447?lnk=gstq=ie7+images+load#ff7cc59bd0cb3447 but with no concrete solution to the problem, that IE7 will wait until all the images are loaded until it will then load the GWT module. Is there a work around for this so that the gwt module will be loaded before the images have finished loading?

Problems getting started with GWT and Eclipse
Hi, I'm running Eclipse 3.4 and used the built-in add software capability to download and install toolkit plugin and app engine. Following the steps in the Getting Started tutorial, I created the StockWatcher application. Then following the instructions to test the default project components, I selected it in the Package Explorer and then from the toolbar clicked run and selected run as a web application. The Eclipse console flickered a bit, but no text appeared and the little bar at the to of the console howed that the program had terminated. No browser ever displayed anything (or even tried to), yet from the tutorial I should have seen 2 browser windows. Any ideas why things aren't working right at step 1 in the tutorial?

Re: How to share RPC service between GWT applications?
You can do this if you place your RPC services in a separate module that is inherited by the two main application modules. In this situation you can specify the RPC servlets in the common module gwt.xml file and this will work for hosted mode, but I think you have to map them separately (i.e. in duplicate) in each main module's web.xml for deployment - AFAIK there is no way around that (app server/ servlet specification issue, not GWT). At run time you will end up with two instances of each servlet loaded by the two main module's classloaders (again app server/servlet specification issue, not GWT) which may or may not present you with an issue depending on what you are doing.

Is there any way to extend the white list of SerializationPolicy.java ?

Re: iText Causing GWT-RPC callback to fail. Need to send to HttpServletResponse?
Alright - thanks. Again, right now it just uses a hard coded string,
which works. However, if a user generates three different forms, and
then refreshes the three new windows (PDF file), the end result is
three copies of the last form that was generated and added to the
token.
Is there anything wrong with using a random number generator to
generate the tokens? Provided the range is large enough, the
probability of two generated forms during a single session getting the
same random number is small, so they should essentially all be unique
nearly 100% of the time. (After all, a user would only generate a few
forms per session, or at most 20 or so).
Is there anything wrong with this scheme?
@flyingbuzz - your PDF looks nice. Right now ours is extremely basic
just posting the details using new Phrase(). I haven't looked into
styling it yet until I get the basic details down. Then I can go in
and style them, but they will probably still be more basic than
yours. They are simple behavior reports for students in school that
displays some basic information about their behavior over the week /
month / etc.

Hi,
You'll have to work out a token generation scheme. If you find a nice

Sessions will typically timeout (the timeout is app server dependent),

Thanks Carl! Your method worked fine. It's almost fully implemented,

there an automatic way of generating unique tokens, or is generateToken
() a function I would write myself and have to ensure that each token
generated was unique?
For now, I just hard coded a random string into the code, which worked
well enough to see that the PDF did indeed open in a new window and
display as expected.
I will also need to figure out the session settings so that they are
invalidated properly, although I think I will need to do a bit more

Re: 1.6 and css hyperlinks
That's not the reason you're initial solution didn't work. If you want it
to work with addStyleName, you have to properly inject the javascript,
otherwise the 3rd party stylesheet you are using (Google's is most likely)
will override your CSS. All you did was remove the styling that would be
applied by the stylesheet so that yours wouldn't be overwritten.
The same thing could be accomplished by adding !important to your rule or
properly inserting it into your gwt.xml module description.

Re: Two clients one session
Sessions are usually bound to a browser, for a given host/Application Context(war), by a Cookie ( likely called JSESSIONID ), if the two browsers share a cookie cache/address space, they'll see the same session cookie, and share the same session.

Re: Load gwt module before image are loaded on IE7
A browser will fetch all resources from a page before executing any Javascript. So move those images into an ImageBundle (you'll get better performance too) or use the Image widget (equivalent to the img in HTML) to add your images using Javascript.

Re: Deferred Bind on Login to load different user interface
Yep you are following my train of thought exactly. I'm thinking in terms of using deferred binding for skin/layout differences it shouldn't be such a bad idea if it's small alterations such as colours/layout. Considering that internationalisation/browser layout differences work along the same lines in terms of the scope of changes. The workflow i've had it laid out in though in my head is like this: 1. default entry point with default permutation is loaded with login form 2. user logs in with user / pass / layout 3. system checks for valid login 4. if successful login redirect back to default entry point with when-property-is name=skin value=GREEN_LAYOUT/ My issue is on the redirect how would i go about setting the property value that i wish to load? Would this be appended to the URL ala locales in internationalisation? This then brings up another issue. If it does involve appending to the URL what if i only wish to make the skin available to only a particular set of users. Else i'm thinking at this point maybe dynamically downloading and loading skin X after login may be a better choice as opposed to deffered binding.

Re: GWT1.6 RPC service with ListObject in return: Serialization pb
GWT needs to know ALL the types that CAN be serialized to the UI at
compile time. It looks at the RPC parameters and return types,
traces their roots and possible sub-classes, and makes sure the proper
serializers/deserializers are present.
First tho, I ask, what good is a ListObject ??? Say this worked...
what would you do with the List in the UI?
Second, ONLY Serializable types can be used with RPC, so the Minimum
that makes ANY sense is ListSerializable. This may work, but the
compiler would then take a large amount of time finding ALL
Serializable classes... bad.
Still, you can then get almost anything in your List... so what do you
do in the client??? Iterate and check instanceof on each item???
IF I had to do this, I would create a marker interface,
public interface DTO extends Serializable
{
}
and make any class that could be used in the UI implement DTO. the
make it ListDTO
the compiler would then only generate serializers for anything marked
DTO, and be much more efficient.
STILL, On the client you don't know exactly what you have in the List,
and any solution to that problem will
be slow and error prone.

Re: File Upload with rpc call
Between two servers yes (just use any regular file-transfer mechanism such as ftp, webdav, sshfs, etc). Between two clients obviously not as that defeats all sorts of browser security. You can't even do that with flash I believe. Maybe in the future there might be some kind of mechanism to establish a connection between browsers directly, but you've got to remember that HTML was created as a client/server architecture all features pretty much assume this behaviour. If you want to transfer files directly between users, then webapps are the wrong tool. Especially with big apps, use something like Bittorrent instead.

Re: Deferred Bind on Login to load different user interface
Generally you can't since when you reload an app you lose state. Now you could of course put in support for your app for restoring state if the user is already logged in (using cookies for persistence - just make sure the cookies have invalid data so that they're never actually sent to the server needlessly). To pick a specific version of the code, load the html page with the appropriate meta tag set in the header. There was a discussion about this in a thread not too long ago.

Re: No JSNI method generated
No, that's wrong since the GWT compiler won't actually define clickTest but
obfuscate it to save on bandwidth. You cannot do it that way.
What you could do, if you were dead set on adding the HTML that way (if
you're going to do it that way, why not just put it into the original HTML
page?), you can do:
public void onModuleLoad() {
RootPanel.get().add(new HTML(h1 onclick=\return
$wnd.h1ClickHandler();
\TEST/h1));
}
private static native void registerOnClick() /*-- {
$wnd.h1ClickHandler = function() {
$wnd.alert(OK);
}
} --*/;
Haven't tested but it should get you on the right track. Optionally, you
could do it as:
private static native String createH1(String text) /*-- {
return 'h1 onclick=jsni name of java function' + text + '/h1;
} --*/;
I would recommend you read try to understand how JSNI works.
the above is extremely redundant. Why aren't you using regular GWT
widgets for this? JSNI is really not recommended for use unless you can
explain why the same thing can't be accomplished in GWT. If you use JSNI,
you're also more likely to cause memory leaks (pure GWT code will not leak
memory).

On Tue, Apr 14, 2009 at 9:02 AM, dflorey daniel.flo...@gmail.com wrote: Good news! Are there plans to consolidate ClientBundle and i18n messages constants? It would be very nice to have a single bundle for all resources of a widget to streamline the widget cusomization. As an interim step, look at GwtCreateResource. It's not particularly elegant, but it does allow for arbitrary consolidation of resources into a single interface. On a longer term, it wouldn't be too hard to incorporate the current I18N interfaces in ClientBundle. -- Bob Vawter Google Web Toolkit Team --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

No update yet, unfortunately. We have to get ourselves organized again now that GWT 1.6 is out the door, and then we'll have a better idea of when it will be available.

[gwt-contrib] Re: RR : Chunk the JavaScript in the initial fragment
It still sounds to me like the route Scott suggested and Bob agreed with would be better, so as to avoid the whole issue of re-lexing the JS during link.

In fact, it might be *exactly* as fun, if you know what I mean. String literals have to be known at parse time, so it seems to me all you have to look for is start/stop quotes (of both sorts) while handling embedded ones of the wrong variety and escaped ones of the right variety. That looks like it can be handled with a single character lookahead scanner, and very little complexity -- what am I missing? It would be awesome if there were a simple lexer available for JavaScript. Given a token stream, brace counting would sound feasible. However, from what I hear it's pretty complicated even to tokenize JavaScript. I don't know exactly what is so hard, but last time I asked, regex literals came up.

Hi arun
U can use GwtSwfExt lib for uploading files(gmail style file upload).
This lib is wrapper on SWFUpload .
