Hi Igor. I think your problem is related to mine:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3652
But I can reproduce it in both hosted mode and in the browser. I think
there is a serialization issue with the GWT RPC when sending inherited
(super-class) fields.

Ordering of rendering

2009-06-02 Thread eggsy84


Hi all,

Using the GWT EntryPoint is there anyway to make sure that the entry
point isn't invoked until the rest of the document is loaded?

I have made a widget that can be shown on various pages and sometimes
due to one thing or another the widget fails to render but when this
happens it stalls the browser and doesn't continue to render the rest
of the document?

Is there anyway to not invoke onModuleLoad until the document has
loaded?

Many thanks,

Eggsy

PS. I'm aware that our architecture should have some form of timeout
really but at the moment this is the most expedient way.

Re: Ordering of rendering

2009-06-02 Thread Ian Bambury

Have you ensured that the gwt script tag occurs after everything else?
Or tried a deferred command in the onModuleLoad which calls a routine to do
everything currently in the onModuleLoad ? That should be queued until
everything else is done.If your other js is deferring stuff too, then a
deferred command in a deferred command would jump it to the end of the queue
again, or failing that, a timer.

Multiple windows code snippets

2009-06-02 Thread Sylvain


Hi Everybody,

Could somebody be nice enough to post snippets of code around handling
multiple windows in a GWT app. I've read the bug #404 entry and the
pieces of suggested workarounds with window.open() but somehow I'm not
connecting the dots.

What I'm trying to achieve is:
- Main window shows list of items in a table
- User selects an item
- User clicks on a 'Show Details' button
- A new window pops up with the details of the item selected in the
parent window

Because of the nature of the information to be displayed and the fact
that several detailed views may be opened at once I am not interested
in using internal dialogs, panels etc.

Thanks in advance.

Regards,
Sylvain

Re: GWT VS GWT-EXT

2009-06-02 Thread Sylvain


I started a GWT project and quickly had the need for more widgets than
what is provided in the standard SDK. GWT-EXT comes up consistently as
a popular library that provides widgets on top of GWT but when digging
into the implementation it is clear that it actually is a binding of a
Javascript UI library on top of the GWT framework.

The situation is tough for developers, it's a bit like the good old
days of Java 1.1 / 1.2 when the Netscape IFCs looked so much better
than the standard widgets and Swing was in it's infancy. At this point
and mostly influenced by the specific project I'm working on I've
decided to stick to GWT alone and not use a not-fully-native library
on top of it. It was a tough call to make, like every time one has to
choose between integrating a 3rd party library that may have long term
caveats or building from scratch and taking the hit upfront.

Re: RPC Serialization of abstract classes


Well, I have finally found the problem:
Drums roll:
The GWT Timer class is not serializable (my super class had a Timer
field buried down in there)! The compiler doesn't complain at all and
when the time to serialize comes it just doesn't serialize the whole
class without throwing any exception. Thanks Paul for your support and
I'm sorry for wasting your time with this.

Re: Ordering of rendering

2009-06-02 Thread Ian Bambury

Yeah, it's just a timer of 1ms as far as I remember, but the browser will
put the request at the back of the queue so unless your other js leapfrogs
it by doing the same trick, it should run after everything else.
The screen will be rendered before it runs, which may or may not be a
problem or an advantage (you can display a progress message, for example)

Re: This html file is for hosted mode support.

did you do a compile before you deployed it.

When you are in hosted mode just tell it to compile the application.
You will see a button in hosted mode called 'Compile/Browse'.  This
will compile your application and launch a browser to view it.

At this point you have all the code compiled and ready to deploy in
your war dir.

Assuming you are using GWT 1.6

Cannot drag and drop out of a ScrollPanel

2009-06-02 Thread badgerduke


Hello:

I am dragging and dropping small HorizontalPanels between two
ScrollPanels.  When there are no scroll bars on the ScrollPanels, it
works just fine.   However, if there are bars present, moving the
panels jsut causes the ScrollPanel to scroll and the dragged panel
disappears as if it is being dragged under the adjacent panel.  This
is hard to picture, I know.  If I drag a panel towards a scroll bar,
instead of being dragged over it, it goes under it and out of sight.

I am using a drag and drop scheme which positions the dragged object
by calling:

AbsolutePanel ap = (AbsolutePanel) sender.getParent();
ap.setWidgetPosition(sender, x + ap.getWidgetLeft(sender) -
dragStartX, y + ap.getWidgetTop(sender) - dragStartY);

Has anybody seen this problem?

Thanks
Eric

Re: Google plugin can not auto create build.xml?

2009-06-02 Thread Miguel Méndez

We opted to remove it to avoid confusion when using eclipse.  The plugin
does not currently have an export ant file option.
However, you can submit an issue for this at
http://code.google.com/p/googleappengine/issues/list .

Re: GWT 1.6 + Spring Security issue

It could very well be. When running a more complex server side (i.e.

 I've posted this to theSpringforums and they mention it's a

 this doesn't seem to be an issue (especially since I package them with
 my app and it works fine).  I'm wondering if somehow jetty orGWTis
 using a class that might be interfering with the resolution of the

 think it's related toSpringSecurity (and not justSpringitself)
 somehow.

 Any ideas?

Re: Composite - can click on one widget inside look like click on the Composite itself?

2009-06-02 Thread Chad


I do something similar with other events, so I would imagine it should
work the same way. I have a class extending Composite that contains,
among other things, a button. When that button is clicked, a
CloseEvent is raised by the class. This is accomplished by having my
class (extending Composite) implement ClickHandler (to receive the
button clicks) and HasCloseHandlersBoolean (so other classes can
receive the CloseEvent being raised). In my onClick method, I issue a
statement like this (this statement exactly to be precise):

CloseEvent.fire(this, true);

I also do something similar with ValueChangeHandler and
HasValueChangeHandlers to allow this class to raise ValueChangeEvent
caused by internal controls. In your case, you will need to create a
ClickEvent with the class as the source and fire it.

HTH,
Chad

 Hi men,
 I am trying to implement my own Composite named MenuItem composing of
 a Grid with 3 cells next to each other and a Label placed in the
 middle cell. I call initWidget(the Grid).

 The issue now is that I register a click handler for the Label which
 should determine if the MenuItem was clicked or not. The Grid should
 not react on clicks, thus I do not register click handler for it.

 Now, naturally, the source of the click event will be always the
 Label. But in my application I need to get as the source of the event
 the MenuItem object, not the Label which composes just a part of the
 MenuItem Composite.

 Is there any smooth way to do that? My only idea is not to extend
 Composite class, but the Label itself and add it in a Grid. Is this a
 correct solution?

 Thanks.

Expire an idle session

2009-06-02 Thread hezjing

Hi

I want the session to be expired if the it is idle for 5 minutes.

I have the following client code after a successful login:

String sessionID = /* (Get sessionID from server's response to login
request.) */ ;
long DURATION = 1000 * 60 * 5;
Date expires = new Date(System.currentTimeMillis() + DURATION);
// the sid cookie will be expired after 5 min
Cookies.setCookie(sid, sessionID, expires, null, /, false);


The problem with the above code is that the session cookie will be expired 5
minutes from the time the session is created and not from the time the last
request to the server.
For example, if a session is created at 00:00, followed by a request at
00:04, the cookie will still expire at 00:05 instead of 00:09.

To do this, I have to reset the expiry time of the cookie in every RPC call
like the following:

public void onFailure(Throwable caught) {
...
// re-calculate the expiry time
Date expires = new Date(System.currentTimeMillis() + DURATION)
Cookies.setCookie(sid, sessionID, expires, null, /, false);
}

public void onSuccess(...) {
...
// re-calculate the expiry time
Date expires = new Date(System.currentTimeMillis() + DURATION)
Cookies.setCookie(sid, sessionID, expires, null, /, false);
}


May I know if there a more elegant way of doing this?

I18N script does not produce maps

2009-06-02 Thread Dominic


When using the i18n script for generating the constant interface, the
maps are not generated as desribed in the documentation

http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/i18n/client/Constants.html

The following properties file

key1 = foo
key2 = bar
map = key1, key2

produces the following interface:

  @DefaultStringValue(foo)
  @Key(key1)
  String key1();

  @DefaultStringValue(bar)
  @Key(key2)
  String key2();

  @DefaultStringValue(key1, key2)
  @Key(map)
  String map();

But accoring to the documentation I would expect to get the following
signature for map():

  @DefaultStringMapValue({key1, foo, key2, bar})
  @Key(map)
  MapString, String map();

What do I need to do that the map is created? Or is there a bug in the
i18n script?

suggestions in richtextarea

hello,
is it somehow possible to provide suggestion in RichTextArea instead
of in SuggestBox?
I noticed in Google Wave presentation video, that their spellchecker
opens a popup with suggestions (corrections) in richtextarea right
under the misspelled word. How is the placement of this popup
computed?  I would like to use something similar in order to allow
suggestions and auto completion of special terms when user is writing
text in richtextarea. But richtexarea doesnt seem to provide any
methot with information about position of cursor.

Raw RPC Serialization classloader problems

2009-06-02 Thread kuvera


Hi,

I have a legacy web application, and I'm creating a GWT interface for
it.
I put the GWT module folder in the project and in Eclipse I used its
src folder as a source folder, so both client and server files are
compiled.
I cannot add new servlets as GWT RPC requires, but I'm trying to use
raw serialization methods and send the payload with RequestBuilder.
On the server side RPC.decodeRequest(payload) throws:

com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
Could not locate requested interface
'com.barra.cp.hal.gwitty.main.client.HashServiceData/904951783' in
default classloader

I run Tomcat from Eclipse, not remote debugging, but as a standalone
instance.
I run a hosted mode run configuration with -noserver, so that tomcat
provides the server-side. The startupUrl is also a tomcat-provided
url.
Both run configuration have the project compilation folder at the top
of the classpath. Both server and client side classes can be debugged
in Eclipse. The hosted mode config also has the gwt-dev jar and the
source files folder in the classpath User Entries.

I would like to ask why the IsSerializable class is not visible for
the deserializer and what that /904951783 means.

thanks in advance,
Laszlo

get child node by name

2009-06-02 Thread acpir


All apologies if this is a really obvious question but after 3+ hours
searching this group and the tubes in general I couldn't find the
answer.

I have xml data that looks like this:
root
  item
item-descriptiona/item-description
item-weight5/item-weight

 /item
/root

The data is in a document object and I've retrieved the node item.

I want to retrieve the value of item-weight.  The element isn't always
the second child and doesn't always exist.  From what I can tell by
reading the docs I would have to retrieve the node list containing all
of the children of item, test each one to see if it was named item-
weight, the retrieve the value of the node that tests positive.

Please tell me there is a more efficient way to do his because I'm
pretty sure there would be performance issues when this operation has
to be performed a few dozen (few hundred) times.

KEY_TAB causes audible beep on FF/Mac....

2009-06-02 Thread Pete


I seem to have found some unusual behaviour - I have captured the
KEY_TAB event in the following code:

public void onKeyPress(Widget sender, char keyCode, int
modifier) {
firedKeyDown = true;
switch (keyCode) {
case KEY_TAB:
parent.doTab(TableCell.this, modifier ==
MODIFIER_SHIFT);
break;
}
}

This causes the warning beep.  The exact same code using the enter key
does not.

case KEY_ENTER:
parent.doTab(TableCell.this, modifier ==
MODIFIER_SHIFT);
break;

Has anyone else experienced this?

Pete

Re: Browser compatibility issue??

2009-06-02 Thread Donald.W.Long


I ran into issues like this also, its how IE7 does the CSS compared to
the other browsers.  You need to setup the CSS for IE7 and the other
browsers.

I use firefox firebug to see how the CSS are setup, that is how they
are shown.  I recommend running your program without the setStyleName
and use firebug to see how the CSS is done and then add the
setStyleName back and see the differnce.

CSS is always hard when dealing with differant browsers.

Hope this helps, not very specific, sorry

 between each row of the vertical panel.  If I remove the style setting
 then the rows stack properly (the latter row immediately beneath the
 former).  Since I can achieve the same results in the display by
 adding an additional empty row or adding another empty panel as

 awkward way to work around the issue.

 Is there a simpler solution?

Re: Alternative Languages?

2009-06-02 Thread Alex Rudnick


Hey Darren,

We don't have specific plans for other languages right now, and
there's a bit about why GWT uses Java over here:
http://code.google.com/webtoolkit/makinggwtbetter.html#introduction

However, the beauty of open source is that everybody's totally free to
implement their own web toolkits with whatever language they like.
There's an independent project called Pyjamas (http://pyjs.org/), for
example, that does something very much like what GWT does, and it uses
Python.

Personally, I'm waiting for the port to OCaml ;)

No. Use getElementsByTagName liberally. Here's one possible scenario

   1. Find the nodes named root: getElementsByTagName(root). Yes, I

   2. for the next node in 1, find the nodes named item:

If this doesn't float your boat, consider more pre-processing on your 
server: use JSON and JSON overlay types on the client side.

 Please tell me there is a more efficient way to do his because I'm
 pretty sure there would be performance issues when this operation has
 to be performed a few dozen (few hundred) times.


GWT doesn't (yet) have a reliable cross-browser XML query language 
implementation. There may be one in the incubator or other GWT-related 
sites.

 Hi all,

I'm developing a new web application base on GWT technology, the name
is gwt-mind-mapping. It's not done yet (is a beta version), but please
have a look for this application in http://gwt-mind-mapping.appspot.com/
and give your opinion.

Re: GWT 1.6.4 war deployment

2009-06-02 Thread Miguel Méndez

We don't currently support exporting to a war from the IDE.  You could do a
clean build in eclipse, then perform a GWT compile, then you can simply war
the contents of the war folder.
We are tracking the export war request as part of the following issue:

Re: GWT VS GWT-EXT

2009-06-02 Thread DaBlick


My understanding is that GWT-Ext development is halted.

Your mileage may be different, but if you are setting up your
technology stack, why pick something with no apparent future?

It's popular now but when something is not moving at all, other things
are bound to catch up and surpass it.

We're using Ext-GWT (also known as GXT) and are quite happy with
it.We've managed to build a HIGHLY stylized RIA with it such that
you'd barely know it was GWT or even GXT for that matter.

 * Use a canvas to draw the lines (in the browser)
 * make each node selectable without editing (you could traverse the

Re: jsni getting rewritten

Hi rjcarr,
Because you can do arbitrary things in an eval, I'm not sure the GWT
compiler will be able to infer that there are types referenced from the JSNI
method parameter list in the eval argument. I could be wrong on that, so
I've cc'ed Scott to double check that assertion.

On the other hand, you could use regular GWT code to perform calculations.
The GWT Java code you write will translate into optimized JavaScript anyway,
so it seems like you could just as well stick with Java code arithmetic and
rely on it to be cross-compiled into similar JavaScript as the one you're
using in the eval.

Hope that helps,

Hi Sumit-

Thanks for the response.  I'm looking forward to hearing from Scott if
he has anything to say.

My example of doing simple arithmetic was only to explain the problem.
 However, if I think about it more, maybe it is still applicable.

Say I have an application that allows users to input arbitrary
(javascript) equations, e.g.:

Math.round(Math.pow(2,z)/2.0))-y-1

(Where x, y, and z are invariable)

Without writing my own lexer, how would I go about trying to find a
result to that?  That's why I figured using eval(), which is a lexer,
is the perfect solution.

Thanks again for the response.

delayTestFinish is not delaying the test

2009-06-02 Thread Igor Moochnick


I'm using the GWT Eclipse plugin with the latest GWT 1.6. My test
looks like this:

public class MyTests extends GWTTestCase
{
public String getModuleName() { ... }

   public void testAddAction()
   {
  MyServiceProxy proxy = new MyServiceProxy(
 new MyServiceCallback()
 {
 public void OnData(Data data)
 {
   finishTest();
 }
 });

   proxy.GetData();   // Execute Web Service (REST) call

   delayTestFinish(6000); // Delay for 1 minute
   }
}

I'm running this test with Rght-Click/Run As/GWT Junit test on the
function.  The test running successfully, and the call to the remote
service is executed, but there is not enough time to get the callback
since the delayTestFinish is not waiting for the specified delay.  In
fact it's not waiting at all - it just jumps through.

When I check the source code for the delayTestFinish function I see
something like this:

public abstract class GWTTestCase extends TestCase {
...
  protected final void delayTestFinish(int timeoutMillis) {
// implemented in the translatable version of this class
  }
...
}

What is the translatable version of the class. How can I see what is
the generated result?  What am I doing wrong?

Would it, though? You're executing, on the client, arbitrary code that
originated from the client/user. It's nothing a user couldn't do with
Firebug or other browser extensions. It certainly looks like the sort
of thing that should send up red flags, but I don't think it's a
problem in this case.

Re: Expire an idle session

2009-06-02 Thread Tony Strauss


What about timing out the session on the server?

Assuming that you're using a Java application container on the server,
you can add the following to web.xml:
session-config
  session-timeout5/session-timeout
/session-config

This will cause the server to time out connections after five minutes
of inactivity.  With this technique, it's actually possible to
intercept requests made after a time out in the onFailure() handler
and to take some kind of action (i.e., redirect to a login screen).

 Hi

 I want the session to be expired if the it is idle for 5 minutes.

 I have the following client code after a successful login:

 String sessionID = /* (Get sessionID from server's response to login
 request.) */ ;
 long DURATION = 1000 * 60 * 5;
 Date expires = new Date(System.currentTimeMillis() + DURATION);
 // the sid cookie will be expired after 5 min
 Cookies.setCookie(sid, sessionID, expires, null, /, false);

 The problem with the above code is that the session cookie will be expired 5
 minutes from the time the session is created and not from the time the last
 request to the server.
 For example, if a session is created at 00:00, followed by a request at
 00:04, the cookie will still expire at 00:05 instead of 00:09.

 To do this, I have to reset the expiry time of the cookie in every RPC call
 like the following:

 public void onFailure(Throwable caught) {
     ...
     // re-calculate the expiry time
     Date expires = new Date(System.currentTimeMillis() + DURATION)
     Cookies.setCookie(sid, sessionID, expires, null, /, false);

 }

 public void onSuccess(...) {
     ...
     // re-calculate the expiry time
     Date expires = new Date(System.currentTimeMillis() + DURATION)
     Cookies.setCookie(sid, sessionID, expires, null, /, false);

 }

 May I know if there a more elegant way of doing this?

 3) If you go to Preferences (Window - Preferences on Linux and Windows,
 Eclipse - Preferences on Mac) - Run/Debug and make sure that Activate the
 workbench when breakpoint is hit and Activate the debug view when
 breakpoint is hit options are enabled?
 4) Can you tell me what is on your project's classpath?

Re: How to disable click events in Grid cell

Hi Suren,
Unfortunately, disable text selection on double click is one of those things
that is hard to prevent across all browsers. I tried a couple of
implementations to disable text selection on double-click, but neither of
them worked.

However, you can use an onselectstart='return false;' attribute which does
seem to work on IE6/7 and Chrome (see code snippet below). Although this
works on Chrome (which is WebKit-based), you'll have to try it out on Safari
to see if it works there as well. This definitely doesn't work on FF3, so
that may hinder your decision to depend on the onselectstart attribute for
text selection prevention.

HTMLPanel panel = new HTMLPanel(div id='grid' onselectstart='return
false;'/div);
Grid grid = new Grid(10, 10);
for (int i = 0; i  10; i++) {
  for (int j = 0; j  10; j++) {
grid.setText(i, j, Bonjour);
  }
}
panel.add(grid, grid);

As a sidenote, you may not necessarily want to disable text selection in the
grid, however. It's generally not a good idea to go against standard browser
functionality that users may have grown accustomed to in their web browsing
experience.

Hope that helps,
-Sumit Chandel

Re: How to GWT enable Spring MVC Web Application

Hi Neeraj,
The answer to how to integrate GWT with your existing Spring MVC Web
Application depends on how deeply you want to integrate GWT into your
application.

For example, if you would simply like to add a few GWT components to your
application pages, all you would need to do is define an binding element
(such as a div id=gwtComponent/div) in the page you would like to
include your GWT component as well as a script tag referencing the GWT
bootstrap JavaScript file.

In your GWT code, you would bind your component to the div by calling
RootPanel.get(gwtComponent).add(mainPanel), for example.

On the other hand, if you would like your user interface to be fully built
with GWT as well as have easy client-server interactions going through your
Spring controllers, a Google search for the terms gwt spring should turn
up some useful results.

If you the level of integration you're aiming for is somewhere in between
the two extremes described above, perhaps you should consider using GWT RPC
for client-server communication and using the RPC servlets as gateways to
your Spring controllers.

GWT RPC:

Reference to interface in another project

2009-06-02 Thread Barry


Hi --

I have seen a lot of posts referring to variants of this problem, but
haven't seen a resolution to this specific situation ... and I'm
afraid I'm not making headway. This seems very simple, but if I can't
do it, please let me know.

I'm running Eclipse 3.4.2 with GWT 1.5.2. I have a perfectly fine GWT
project that I'd like to have reference constants defined in an
Interface in another project (which itself contains only Interfaces).
Eclipse seems fine with this, as long as I use Build Path to identify
the external project in the Projects tab.

GWT, though, gives the error
org.paceproject.palms.schema.XSDDefinitions can not be found in
source packages. Check the inheritance chain from your module; it may
not be inheriting a required module or a module may not be adding its
source path entries properly.

From other posts, it seems like GWT is trying to tell me it's going to
have trouble loading the external project at runtime.

All I'm using this external project for is to provide definitions
common to all of my applications (including my GWT application).

Is there a particular way I should be defining my external project
(i.e., the one that contains
org.paceproject.palms.schema.XSDDefinitions)? Or is there something
particular I should be doing to my GWT project's gwt.xml file??

Or should I be trying to import symbols common to multiple projects in
a completely different way??

Thanks for any help/advice you can give me.

(FYI, the offending import in my GWT project is import static
org.paceproject.palms.schema.XSDDefinitions.*; and the Interface in
the external project is

package org.paceproject.palms.schema;

public interface XSDDefinitions {

public static final String XSD_String = xsd:string;
}

Re: Cannot get Application to Compile and run in Firefox 3

Could you try compiling your application in PRETTY mode and seeing if the

Also, did this occur when hitting Compile/Browse from hosted mode, or did

I want a GWT control that's a TextBox with the label as light grey

Re: Cannot get Application to Compile and run in Firefox 3

Also, you can compile in PRETTY mode using the Google Eclipse Plugin by
following the steps below:
1) While your project is open, click on the Run... drop-down arrow to open
the list of run configurations.

2) Select Run Configurations...

2) In the Run Configuration dialog, select your project's Web Application
launch configuration.

3) Navigate to the GWT tab

4) Select the Pretty option from the Output style drop-down box.

5) When you hit Compile/Browse on your next hosted mode launch, the
generated output will be human-readable JavaScript. This will either give us
more hints in the generated error message, or will work in Firefox 3, in
which case there may be something to investigate on the GWT side of things.

Hope that helps,

GWT and ExtGWT Licensing

2009-06-02 Thread Kango_V


I just wanted to ask you guys about this topic as our IP lawyers have
found a potential problem.

* ExtGWT extends classes in GWT therefore creating a derivative
work.
* ExtGWT is licensed under the GPLv3 and GWT under ASFv2.

Now, we know that these are compatible.  But, only ONE WAY!

You can include GPLv3 code in your ASFv2 licensed project, but NOT the
other way around.

So, if I wanted to distribute my ExtGWT app under the GPLv3 (open
sourcing all my code which does not require an Ext license) I cannot,
as I cannot relicense the ASF licensed code (GWT).

As far as we can see there is NO way of legally distributing an ExtGWT
applicattion under the GPLv3.

IANAL, so I can only go on what our lawyers tell me.

This is indeed a blow to us, as I cannot see a way round this.  If any
of you have distributed an ExtGWT app under the GPLv3, then you have
broken the terms of the ASFv2 and therefore have no rights to
distribute GWT!

I'm off to bed now :(

Re: GWT and ExtGWT Licensing

2009-06-02 Thread Kango_V


This is the section from Apache about compatibility:

This licensing incompatibility applies *only* when some Apache project
software becomes a derivative work of some GPLv3 software, because
then the Apache software would have to be distributed under GPLv3.
This would be incompatible with ASF's requirement that all Apache
software must be distributed under the Apache License 2.0.

As far as the license is converned, when ExtGWT extends a GWT class it
is a derivitive work in the eyes of the GPL, so the above clause is
true.

GWT Project servlet-mapping clarification - how mapping happens

2009-06-02 Thread Tharindu Madushanka


Hi,

Perhaps this might not be the correct place to ask this. But please
kindly tell some answer to this.

I am new to web development and I started reading about GWT, and when
I look at web.xml I see the

 servlet
servlet-namegreetServlet/servlet-name
servlet-classcom.gwt.test.server.GreetingServiceImpl/servlet-
class
  /servlet

  servlet-mapping
servlet-namegreetServlet/servlet-name
url-pattern/calc/greet/url-pattern
  /servlet-mapping

I used ant script created to run the application in hosted mode. When
I run the application in hosted browser it shows the url as
http://localhost:8080/calc.html
Perfectly I could access this Url from other browser as well. But my
question is what is the purpost of  url-pattern/calc/greet/url-
pattern . I tried to access the url by typing http://localhost:8080/calc/greet,
but it displays following error - HTTP Error 405

HTTP method GET is not supported by this URL

RequestURI=/calc/greet
It it directly access from url by typing http://.../calc.html, then
what is the purpost of url-mapping tag. I saw on blogs we can add
several this kind of mapping. But still how it knows this request maps
to this url-pattern. In our case, I only request calc.html and then
how web.xml file knows I requested calc/greet.

Please calrify a little on this. I am so confused about how this
happen.


Kind regards,
-Tharindu

Re: Array vs. ArrayList

Hi Jacob,
The difference between the two depends on what you do with them. The
emulated ArrayList provides a number of convenient features. If you use
ArrayList, you will definitely pay the cost of increasing the size of your
JavaScript, but that might not be a problem if you need these features
anyway. The implementations for the ArrayList convenience methods are
implemented as efficiently as possible, so you would end up having the same
speed of execution if you were using Array and implementing similar
functionality as the ArrayList class around the Array type.

You can take a look at the features available in the ArrayList by checking
out the emulated class source code at the link below. If you need these
features, by all means use the ArrayList class.

Emulated ArrayList class:
http://google-web-toolkit.googlecode.com/svn/trunk/user/super/com/google/gwt/emul/java/util/ArrayList.java

However, if you don't need these features, you will probably be better off
using a regular array.

Hope that helps,

 Hi,

 I used ant script created to run the application in hosted mode. When
 I run the application in hosted browser it shows the url 
 ashttp://localhost:8080/calc.html
 Perfectly I could access this Url from other browser as well. But my
 question is what is the purpost of  url-pattern/calc/greet/url-
 pattern . I tried to access the url by 
 typinghttp://localhost:8080/calc/greet,
 but it displays following error - HTTP Error 405

 HTTP method GET is not supported by this URL

 RequestURI=/calc/greet
 It it directly access from url by typinghttp://.../calc.html, then
 what is the purpost of url-mapping tag. I saw on blogs we can add
 several this kind of mapping. But still how it knows this request maps
 to this url-pattern. In our case, I only request calc.html and then
 how web.xml file knows I requested calc/greet.

 Please calrify a little on this. I am so confused about how this
 happen.

 Kind regards,

Re: GWT + JAAS

2009-06-02 Thread Adligo


Hi All,

   Its fairly simple take a look at Spring Security for some examples,
the Subject just ends up in the HttpSession.  You can use a HttpFilter
to check it to block request to your RpcServlets, and you can login to
your jboss JAAS session from the Servlet/Filter web code, just like
you can from a stand alone app (for EJB JAAS).
Having said that there are also a number of other issues, what
happens when your Session times out, (some sort of error handling/
prevention in GWT is needed to detect this, or keep it from
happening).  Also I the user opened more than one Window are you going
to open a new session are you going to have them log in again for each
window?

   I am working on (have identified) solutions to all of these
problems and If you need help let me know (code/time for sale).

Cheers,
Scott

How to set iframe frameborder attribute

2009-06-02 Thread babyblue007


Hi,

I'm using com.google.gwt.user.client.ui.Frame to embed an external
url. There seem to be a small inset border even though I have
everything set to 0 in the css. I think this is because of iframe has
a separate frameborder attribute. How can I set this attribute? I
don't see the function in Frame, there is one in IFrameElement, but I
can't figure out how to go from Frame to IFrameElement.


Frame frame = new Frame(url);
frame.setStyleName(widget-Frame);


.widget-Frame {
  margin: 0px;
  border: 5px solid blue;
  padding: 10px;
}


Thanks in advance.

Re: GWT Theme Like Google

2009-06-02 Thread Carl Pritchett



 GWT-Ext is free for commercial?

Yes it is free - though you may want to look at SmartGWT as well which
also has a free version (the enterprise version is not free, but
just for a good look and feel the free version is fine). A lead dev
from GWT-Ext moved to SmartGWT.

ExtGWT is another commercial framework version (GPL - only free if
your app is also open source).

Also there is gwt-mosaic http://code.google.com/p/gwt-mosaic/ (see the
demo here: http://69.20.122.77/gwt-mosaic/Showcase.html - click the
buttons on the top right to change themes).

Of course the other option is to build your own theme (or get your
css / design enabled friend to build it for you).

I'm interested in building compatible themes for Smart / ExtGWT  so
that widgets from either could be used together... anyone else like
that idea?

Carl

Re: GWT Project servlet-mapping clarification - how mapping happens

2009-06-02 Thread Jim


In your example, once you type  http://localhost:8080/calc/greet in
FF, it is a synchronous regular request in Get method. Your servlet
doesn't override doGet method and
com.google.gwt.user.server.rpc.RemoteServiceServlet returns HTTP Error
405  to your request. In GWT application, it is a asynchronous RPC to
your servlet and you must implement the following methods in your
widgets:

public void onFailure
(Throwable caught) {
}

public void onSuccess(Mails mails) {


}

 My understanding is that GWT-Ext development is halted.

A active replacement is SmartGWT (has a free LGPL version).

Note that Ext-GWT is not free for commercial use - it uses GPL

Don't obfuscate Java methods when passing instance to JavaScript

2009-06-02 Thread jarrod


I want to write a small library API which will expose certain
classes of Objects and well-known methods on them for plain-old
JavaScript to invoke.

Creating the API isn't too hard, and using JSNI, I'm able to create
methods in JavaScript that call back to the GWT (obfuscated) code.
What I haven't figured out how to do is prevent the instance methods
of a Java object passed to JavaScript from being obfuscated.

Say I have a Java class:

class Foo {

  public void doBar() {
  // ... something
  }

}


Now in my EntryPoint class, I'll add some JSNI to expose the Foo
constructor:

public native void onModuleLoad() /*-{
  $wnd.Foo = function() {return @Foo::new()();}
}-*/;


Okay, that all works great. And now from JavaScript, I can do this:

var f = new Foo();


Great. Now I have an instance of Foo. But how can I be certain that
'f' will have a 'doBar()' function?

f.doBar();

Re: Don't obfuscate Java methods when passing instance to JavaScript

2009-06-02 Thread jarrod


One thing I tried was adding an 'export' method to the Foo class:

class Foo {

  public Foo() {
this.export();
  }

  private native void export() /*-{
this.doBar = function() {th...@foo::doBar()();}
  }-*/;

  public void doBar() {
  // ... something
  }
}


This causes, on creating an instance of Foo, the appropriate API
methods to be exposed in JavaScript. However, when running in hosted
mode, I get all kinds of Malformed JSNI Exceptions, whining about how
the 'doBar' field is not found.

PagingScrollTable not removing row

Re: Hosted mode

 Push the button GWT Compile Project
 Compile your project setting log level to Spam
 Go to Debug Configurations , on the 2nd tab GWT of your project
 set log level to Spam.
 Run Debug as... ( your project )
 Make your breakpoints on your project
 Then press Compile/Browse onHostedMode
 Once it fininshed press Refresh onHostedMode

Thanks, this helped me make some progress! Eclipse caught the
breakpoint and switched to Debug perspective. I was able to step
around, inspect variables, and so on.

When I changed the code and saved, the hosted-mode browser stopped
responding to events. When I stopped and restarted the debugger,
breakpoints were again ignored. A couple of cycles of Compile/Browse
and Refresh got breakpoints triggering in Eclipse again. I tried
dialing the logging level back down but that left Eclipse aloof.

It's not elegant, but it's a workaround!

GWTetris - enjoy it :)

2009-06-02 Thread Janusz Prokulewicz


Hi everyone!

I'd like to invite all of you to play my own Tetris which I
implemented with GWT. It's called GWTetris :p and I hope you'll enjoy
it :) I added high scores feature so I think it'll be fun.

You can find it here:

Greetings,

Janusz Prokulewicz



BTW I'm looking for a job in Poland as a GWT developer (more or
less)...

Re: Tab Panel does not resize for FlexTable

   Hi Everyone,

   I'm hoping someone can help me out with a really frustrating issue
   I've been having. I've searched the web for days on this and have
   found nothing. My issue is that I have a TabPanel with a number of
   tabs on it. Each tab has a similar sort of layout with a text box, a
   button, and a flextable. The flextable initially starts out invisible
   (.setVisible(false)). When the user clicks on the button a simple
   database lookup is performed and the flextable is populated and made
   visible. The problem is, the TabPanel does not expand to accomodate
   it.  I only see the first couple of rows of the tab panel. There is no
   scrollbar, but I can scroll the window by selecting the table and
   dragging the mouse inside of it. Changing tabs and changing back
   causes the window to resize.

   I have not been able to find a redraw method or any other way to force
   the widget to update to accommodate the larger child. I've tried
   setting it to invisible and back to visible again to cause it to
   resize, but nothing I can do from code seems to have any effect. I
   can't have the users clicking another tab every time to get their
   window to resize. Is there any solution to this problem? What can I
   do?

   Thanks,
   Troy.

Re: How to disable click events in Grid cell

2009-06-02 Thread mP


hi

Unfortunately there is no universal way to disable text selection via
mouse dragging that works in all browsers.

If I recall correctly to disable text selection one must add the event
listener that Sumit suggests, but this only applies for Ie and maybe
opera. For the others one must add a css property. I can't recall the
exact property names but do a quick search on mozillas mdc to get the
css property name for ff and repeat for webkit.

The FF property was called sonethi g all g the lines of moz-
selection...

 Hi Suren,
 Unfortunately, disable text selection on double click is one of those things
 that is hard to prevent across all browsers. I tried a couple of
 implementations to disable text selection on double-click, but neither of
 them worked.

 However, you can use an onselectstart='return false;' attribute which does
 seem to work on IE6/7 and Chrome (see code snippet below). Although this
 works on Chrome (which is WebKit-based), you'll have to try it out on Safari
 to see if it works there as well. This definitely doesn't work on FF3, so
 that may hinder your decision to depend on the onselectstart attribute for
 text selection prevention.

 HTMLPanel panel = new HTMLPanel(div id='grid' onselectstart='return
 false;'/div);
     Grid grid = new Grid(10, 10);
     for (int i = 0; i  10; i++) {
       for (int j = 0; j  10; j++) {
         grid.setText(i, j, Bonjour);
       }
     }
     panel.add(grid, grid);

 As a sidenote, you may not necessarily want to disable text selection in the
 grid, however. It's generally not a good idea to go against standard browser
 functionality that users may have grown accustomed to in their web browsing
 experience.

 Hope that helps,
 -Sumit Chandel

[gwt-contrib] [google-web-toolkit commit] r5490 - two changes to java.util.Date in an effort to track down a very intermittent


Author: j...@google.com
Date: Mon Jun  1 22:59:06 2009
New Revision: 5490

Modified:
trunk/user/super/com/google/gwt/emul/java/util/Date.java
trunk/user/test/com/google/gwt/emultest/java/util/DateTest.java

Log:
two changes to java.util.Date in an effort to track down a very intermittent
failure on IE.  IE doesn't provide useful stack traces for JS-initiated
exceptions, so all we know is that jsdate is uninitialized or not an object
at some point when it is dereferenced.  The changes are:
  - use a JSO field storing the JS Date object rather than
making an expando on the underlying object (which
couldn't ever work in hosted mode, but since this is a
JRE emulation class it didn't have to)
  - add checks before each dereference of jsdate to see if it has been  
mangled;
if so throws a Java exception so we can get a good stack trace.

This does add some overhead, but it shouldn't be too bad.  This is a  
temporary
change that will be removed once the cause is found.
