Re: Should I use HTML5 canvas just to create my own slideshow reader ?

2012-06-07 Thread ashwin.desi...@gmail.com

there are multiple options available apart from HTML5 canvas.

1. RapahelGWT (this is an extension of Raphael JS for GWT), using this
images would be rendered as SVG. And raphael works with lower versions of
ie as well http://code.google.com/p/raphaelgwt/
2. you can also look at a SlidingPanel (example of this is provided in
expense tutorial), and customize it to load your images.
3. vectomatic (gwt project available), an svg & html5 canvas plugin for
GWT.  http://code.google.com/p/vectomatic/

svg is supposed to be more suited for static images and interactivity.
HTML5 canvas when there is lots of animation/ computations involved.

the following video link provides a good introduction to html5 and
showcases differences between svg and canvas

Should I use HTML5 canvas just to create my own slideshow reader ?

2012-06-07 Thread regnoult axel

Hello,

I am trying to develop my own slideshow reader (you just see the albums 
fotos in the full screen mode and slide them).
I started using HTML5 canvas but just because it was more "modern" but IE8 
does not support HTML5 canvas. So my question is :  "Should I use HTML5 
canvas to do my slideshow (I will need a caroussel and animation between 
images) ?" Could you argue your answer (because maybe HTML5 canvas are more 
interesting to do more complicated things) ?

Thanks you,

MVP Framework

2012-06-07 Thread titowinky

Is there any example here (other than the Contacts tutorial) about the
MVP framework with detailed explanation? The contacts tutorial seem to
jump ... not a thoroughly explained article in my opinion. There are
parts (class/package)of the structure in the contacts tutorial which
was not used by my instructor but still worked. Which is possible to
remove and which is not?

Getting Server Data From Node.js

2012-06-07 Thread Kuenga

Hi
,
At the client side i have the following

Window.alert("Connecting to server");
String Strurl = "http://127.0.0.1:1337/";;
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, 
URL.encode(Strurl));
try {
  Request request = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
// Couldn't connect to server (could be timeout, SOP violation, 
etc.) 
}
public void onResponseReceived(Request request, Response response) {
  if (200 == response.getStatusCode()) {
  // Process the response in response.getText()
  Window.alert(response.getText());
  }
  else {
// Handle the error.  Can get the status text from 
response.getStatusText()
  }
  
}   
  });
  Window.alert(request.toString());
} catch (RequestException e) {
  
}

I have the following Test.js

http.createServer(function (req, res) {
 response.writeHead(200, {"Content-Type": "text/plain"});  
res.write("From node js");
}).listen(1337, '127.0.0.1');


I run the Test.js, using node.exe to start the server. I am able to view 
'From Node.js' on the browser. 

But when i access the same address from GWT, i donot see any thing.

How to i get the text 'From Node.js'  from GWT. 

Basically i have string of number in the form (2,3,4,5) at the node.js 
server side but i want this data to be populated in an array at GWT side.

How to do it ?

Thanks

How to update GWT CellTree data model preserving the node open states?

2012-06-07 Thread bogyom

Hi,

I'd like to implement a hiarachical task viewer with CellTree control.
Task states are on the server side. The client shows the task tree and
updates it say every 2 second. Each task has a progress info
displayed. If a task finised it is removed from the tree.

The CellTree with async data procider works fine. My problem is how to
do the 2 sec update preserving the mode open states? Right now I call
updateRowData for the root this refreshes the tree but all node gets
closed.

Any suggestions?
Thanks
Gyorgy

Running GWT Compiler for multiple modules

2012-06-07 Thread Steve



I don't know alot about how the GWT compiler works but I have an 
application with two entry point modules that uses an ant build and I have 
a question regarding the compiler's performance.  The applications use 
GwtQuery which generates a deprecation warning during the compilation.  
When the ant build runs the GWT compiler twice, once for the first module 
and then again for the second, it looks like the compiler builds GwtQuery 
once for the first module and then reuses that when building the second 
module.  When the ant build runs the compiler once, passing in both modules 
as arguments, it looks like it has to recompile GwtQuery when building the 
second module.  So why is it still about 40% slower to compile the second 
module when running the compiler twice if it's reusing the cached GwtQuery 
compilation?

This opens for a flash moment and then disappears. I read that  Apache

I try to run ant.bat file , even that is not working.

Am I missing something in setup.I am stuck.

Display images from external folder

2012-06-07 Thread Pablo

Hello,

I would like to display images in my GWT webapp from a $HOME folder.
Those images are regularly updated by a local process which has no
permissions to write into the WAR folder.

I've been googling and I've found some suggestions at Tomcat's forums
proposing to modify the web.xml file to expose a local file in the
server:



But this doesn't seem to work with GWT...

Any ideas to solve or workaround this issue?

Thanks

Re: Generate URL to image stored on server

2012-06-07 Thread Nader

Image example = accessURL + "card_designer/exampleImage.jpg"

This only works if "card_designer" folder is under your Web Root so
servlet container/Http server could serve it. And that's not a good
idea to store
contents

On the other hand your current working directory is not your Web root!
So new File("card_designer") wil create a directoy under your current
working directory.

 As Piro said you should store your contents (images) some where in
your server and serve file contents yourself( Write contents in
response ).

Looking for Printing suggestions

2012-06-07 Thread Thomas Mancini

Hello All,

I am currently working on a GWT application that requires report
printing.  The use can select report parameters from a screen, and
upon clicking print we would like to display the file as it is being
generated.  Currently we have server side code that is generating HTML
and writing it to a file.  When the user clicks print, an RPC is being
made to pass the report parameters to the server and begin the
report.  A second RPC is made after the report has started to obtain
the report's URL.  From here, we are creating a Frame and setting the
URL to be the URL retrieved by the second RPC.

The issue I am currently running into, is that when setUrl gets
called, it only displays as much HTML that was contained in the file
at the time of the call.  What would be the best way to refresh just
the frame containing the HTML report?  It appears making subsequent
calls to setUrl passing in the same Url each time would do the trick,
but it actually doesn't seem to contain the additional content that
would've been written since the last call.  It is also resetting the
vertical scroll bar's position each time back to the top of the bar
which is something else I would like to prevent.  Is there a better
way to go about doing this?

Thanks.

entries, but the CellList has a border and don't show a scrollbar. My 
questions are:

   - how could I get rid of the border
   - how could I show the CellList with a scrollbbar, adding it to 
   ScrollPanel doesn't help.
   - There is an example on the site 
   "http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellList"; but the 
   source seems to be not complete, is it possible to download a full example 
   source?

With regards

Rafal Ziolkowski

Invoke external servlet from gwt client

2012-06-07 Thread Hamid OUIKENE

Hello everybody,

I have a servlet running in an external server that returns a simple
text (text/plain).
I am trying to invoke that servlet from a gwt client using
RequestBuilder:

private static final String SERVLET_URL = "http://ip:40802/MyApp/
servlet/GwtServlet";
...

RequestBuilder reqBuilder = new RequestBuilder(RequestBuilder.GET,
SERVLET_URL);
try {
reqBuilder.sendRequest(null, new RequestCallback() {

@Override
public void onResponseReceived(Request request, 
Response response)
{
System.out.println("Response: " + 
response.getText());
}

@Override
public void onError(Request request, Throwable 
exception) {
SC.say("Failure");
}});
}
catch (RequestException e) {
e.printStackTrace();
}

The problem is that response.getText() returns an empty string. When I
invoke the servlet from Firefox, I get the string returned by the
servlet.

Is there a better way to get the string returned by the external
servlet in my gwt client?
Thanks

Re: Type '$Proxy86' was not included in the set of types which can be serialized by this SerializationPolicy

2012-06-07 Thread Michael Nascimento

It happened to me recently. This means an object returned by your
server-side code is actually a dynamic proxy. Hopefully by reading the
whole stack trace you might figure out which object in your graph is
the proxy. Then, you need to replace it by a serializable
implementation.

I am pretty sure you can debug GWT's code to find out exactly which
object is a dynamic proxy, but following the stack trace might provide
a quicker answer.

I am in need of logging every GWT method's entry and exit point. Is

Re: GWT JSNI Callback

Regarding callbacks there is one more error I am getting:
Only one JavaScriptObject type may implement the methods of an interface 
that declared methods.

This
gwt-2.4.0/doc/helpInfo/jsoRestrictions.html
explains alot. But why nobody tell me that in the past? I mean tutorials, 
talks?

Re: Question relative to popup and mouseListener...

2012-06-07 Thread regnoult axel

Hi Joseph,

I think you give me a trick here (the mouse under the popup from the 
begining)...but it does not solve my problem, because, for design reason, I 
need to adjust the popup position (and it will not be just under the mouse 
position).

I think, it should be have an invisible panel, greater than the original 
one, in order to listen the events.

Cheers,

Re: Resubmitting RequestFactory request when server side logic requires it

2012-06-07 Thread Ryan McFall

Thanks, Thomas, I searched through the methods in
ServiceLayerDecorator for something like this, but somehow missed
these.

Using report() from with the ServiceLayerDecorator doesn't allow me to
re-fire the RequestFactory request, giving me the "A request is
already in progress" error.  If I call die() then the exception is
still printed out, but the onFailure method of the Receiver is in fact
called, and I can re-fire the request.

Re: Resubmitting RequestFactory request when server side logic requires it

2012-06-07 Thread Thomas Broyer

If you go the ServiceLayerDecorator route, you can no longer use an HTTP 
status detected by a custom RequestTransport, you're pluggin *into* the RF 
protocol, not *around* it.
Try using the die() or report() methods from ServiceLayerDecorator and see 
how they behave.

Re: Resubmitting RequestFactory request when server side logic requires it

2012-06-07 Thread Ryan McFall

I'm well on my way to getting this to work.  I can determine whether
the method to be invoked requires authentication, and whether or not
the user is currently authenticated.

Currently, what I've done is defined a new runtime exception and
thrown that exception in my ServiceLayerDecorator if an
unauthenticated user tries to invoke a method requiring
authentication.  I've then overridden doPost in my sub-class of
RequestFactoryServlet to catch this exception and set the status code
of the response to be 401.

Unfortunately, this doesn't quite work.  I get the following in my
server console when this exception is thrown by my code:

SEVERE: Unexpected error
edu.hope.cs.surveys.editor.server.SessionExpiredException: Session
expired
at
edu.hope.cs.surveys.editor.server.ActiveSessionDecorator.invoke(ActiveSessionDecorator.java:

133)
at
edu.hope.cs.surveys.editor.server.JandyRequestFactoryServlet.doPost(JandyRequestFactoryServlet.java:
28)

I see that SimpleRequestProcessor has a setExceptionHandler method
which is responsible for creating a ServerFailure object.  Do I need
to provide a custom exception handler to the RequestProcessor?  Or is
there some other way of catching the failure caused by the invoke
method of my ServiceLayerDecorator?

Thanks,
Ryan

Re: Server error code 413 - Request entity too large

2012-06-07 Thread Jens


>
> I'm getting a very strange error here. When creating a new entry to an

This basically means that your data you send to the server is too large and 
hits a limit configured somewhere on your server. So you should check how 
large your request is that fails and check your server documentation what 
default values apply for maximum form uploads, header/request/response 
buffers, etc and increase them as needed.

However, the strange part is: I use this same creation in other place and 
> it works just fine. 


The data you send to the server is probably just a tiny bit smaller and 
thus it works because you don't hit a server limit anymore.
 

> In addition to that, this problem only happens when I'm in development

>

That would mean that your development mode server (GWT's embedded Jetty or 
anything else if you use -noserver) is configured differently (has 
different default values) than your server you deploy to. Or you possibly 
have load balancers in front of your deployment servers so that the whole 
situation is a bit different.

In general its not bad seeing this error because it protects your server 
from being knocked down with very large (denial of service) requests. So 
don't go crazy and configure your server to accept 1GB of POST data or 
something. Configure it to a value that suites your needs.

Re: Generate URL to image stored on server

2012-06-07 Thread Derek

Because you need to use GWT.getHostPageBaseURL() not
GWT.getModuleBaseURL() (or use modulebase, but prepend "../" to your
filename). I assume the actual url to get the image is
http://127.0.0.1:/card_designer/exampleImage.jpg . That should get
the image.

BUT, going back to the "working directory" thing, it IS problematic to
write files there. At least, it is if you expect those files to be
there long term. Every time you redeploy a war in production, your app
server (tomcat, glassfish, whatever) will overwrite everything in the
directory which will erase working directories like card_designer. If
you just need some temporary space to store an image while the user
does things like cropping the image and then they download the
finished product, then that might be fine. But if they expect that url
to work long term, I wouldn't use that space.

(Also, don't know if you've considered the problem of lots of people
uploading images named the same thing or not.)

I recently had to do something similar to what you did. We have a
directory mounted on our production servers that holds uploaded images
(and isn't accessible via the web). When someone uploads a file, I
check the MD5 hash of the file to see if it's a match of another image
(in my use case, it's very probable that a user will upload the same
image or images every time they use the app). If it's not, then I
write the file to the shared directory in the MD5hash.ext format.
Either way, I then return the calculated filename to the GWT code.

The GWT code then immediately executes a request to a servlet hosted
at "/mymodule/images/*" and uses the path info to get the filename and
goes to look it up in the shared directory and relays the data through
the servlet.

Hope that's all clear enough.

Re: Hyperlink/Anchors: Passing data in Places

Duh. Completely looked past that little fact.

So, something along the lines of a PlaceHyperlink Factory using @Assisted
to get the Place into the PlayHyperlink and a provided=true should get the
job done.

Depends how you do it; but given that it's created by UiBinder and not by 
GIN (unless you use @UiFactory or @UiField(provided=true)), you have to 
take explicit action to inject it with GIN. You should be able to do 
"instance injection" instead of "static injection" if you prefer (declare a 
method on your Ginjector taking a PlaceHyperlink as argument and with a 
void return-type, then call it with a PlaceHyperlink for an equivalent to

Someone else will have to answer that for you. I'm using GWT RPC almost 
exclusively. When I use JSON it's as I described--send a JSONObject as a 
string, parse it back to a JSONObject, and process. There are places in my 
project that it's the handiest format available.

You can either use a @UiFactory or use @UiField(provided=true) in your 
views (but that's a lot of boilerplate) or use a static field and 
requestStaticInjection(PlaceHyperlink.class) in your GinModule. I don't 
quite like it but it works, and I've been using it for the past year on a 
few widgets (particularly SuggestBox-like widgets, providing them the 
RequestFactory).
There's an issue on the tracker about making UiBinder more GIN-friendly but 
that's not an easy patch…

Server error code 413 - Request entity too large

2012-06-07 Thread Aldo Neto

Hi,

I'm getting a very strange error here. When creating a new entry to an
entity, I'm getting a "Server error 413". However, the strange part is: I
use this same creation in other place and it works just fine. In addition
to that, this problem only happens when I'm in development mode. When I
deploy the application, the error doesn't happen.

I understand that the description I provided is very vague, but I found
nothing on this subject on the web and I have no idea how to debug it. Can
anyone help me pointing me the place where I can start to debug and
understand what is wrong with my app?

Thanks,
Aldo

need to pass through a PlaceHistoryMapper.

I have GIN set up, so I'm trying to inject my PlaceHistoryMapper into my
PlaceHyperlink (as a field injection - to avoid the missing no-arg
constructor problem), but no dice. That PHM is always null (although it
works fine in other places when constructor-injected).

I don't totally understand why this doesn't work. Any thoughts how to
implement a PlaceHyperlink with UIBinder and GIN?

SuperDevMode and GwtGenerators

2012-06-07 Thread Gal Dolber

Are IncrementalGenerators working on the SuperDevMode?

I'm trying to make my gwt generators cacheable, and everything is working
on DevMode, but when running on SuperDevMode
context.isGeneratorResultCachingEnabled() is always false.

Right now the biggest project I have is taking 35s to refresh on
SuperDevMode(when it takes a few seconds on DevMode). And I'm hoping this
will speed up things.

Any help is appreciated
