Stefan,

It's a bit against the idea of GWT. GWT forces all code to be in one
compilation.

But I understand the requirement (I have exactly the same requirement).

What I currently do is load the GWT subapplications in an IFrame and I
communicate between the IFrame and main application through JSNI code.
It's not nice but it works.

Since 1.5 it should be possible to skip the IFrame part but then you
root application should instrument the sub applications where they are
allowed to render themselfs. The communication between the
applications still needs a roundtrip through JSNI. GWT obfuscates and
compresses the method names so you need to publish the API that you
want to use between them using JSNI.

You have to think about things like timing. These apps will launch
asynchronously so you can not just blindly start calling them.

 Hi all,

 I am to develop a GWT application that shall consist of a main
 application that is used to start and control the execution of sub
 applications. The sub applications are not now at compile time of
 the main application. They are identified by IDs and should be
 startable by these IDs.

 In Java I could use reflection to instantiate the sub applications and
 use interfaces that must be implemented by sub applications in order
 to control them.

 Is it possible to achieve something similar with GWT? The sub
 applications should be compilable into JavaScript independently of
 the main application and must be dynamically loadable by the main
 application.

 Thanks for your attention,

what is the exact syntax for -syle pretty?
I've tried to add line
arg value=-style PRETTY/
  but there was just compilation error about unknown argument.
Can anybody send me exact line please?

Re: How can you wait until GWT is ready externally? (after onEnterModule)


Doug,

I see your point. Maybe you should address this question with the GWT
contributors ? I think you make a valid question. In theory it should
be possible with a custom linker, but it would be nice that this
linker was there already.

You might indeed have to question if GWT is the best choice if you
actually want your API to be exposed as pure JavaScript (as the
preferred or even only way of using it).

Having a callback does not sound as a big drawback to me. Sometimes
you have to trade off your API to the ease of developments as well.
The main advantage of downloading and intialising asynchronously is
that you give CPU back to the browser to render the UI. so the intial
wait time is lower.

 Quick answer is: If you're providing a series of APIs to a third
 party, you:
 1) Don't want to give them the source code to recompile them
 (potentially).
 2) Don't want to make their life difficult by forcing them to
 recompile.
 3) Don't want to step outside of what is 'normal' for a JS library (no
 extra custom ready functions...)

 I understand what you're saying; yes, linking it all together is more
 efficient. Yes, you can bind everything together that way and you
 don't need multiple ready functions. Its a great way of building a
 rich net app.

 However, for JS mashups, you don't want a single page application that
 does everything. You want something that compiles into a generic
 robust usable JS API, that is easy to use and obviously interact with
 other JS APIs.

 Incidentally, as I mentioned, the javascript isn't being loaded in an
 iframe. I'm compiling in xs (cross site scripting) mode, which means
 the JS is added as an inline element in the head. The google code
 launcher specifically waits until after everything else before it
 launches itself (I presume to ensure the DOM is ready before kicking
 off the application init), but I would have been pleased if maybe the
 module constructor was run on load, and only onModuleLoad waited until
 after body.onload was called. Oh well.

 I've come to realize that GWT is ill suited to what I'm doing. I'm
 quite disappointed really.

 I'm not 100% following your question, so excuse me if my answer does
 not match your question.

 Why would you need to have a toBeCalledByGWT for every method you want
 to expose from GWT ?

 I presume you have created an API in GWT and want to expose it outside of 
 GWT ?
 Just make sure that the onModuleLoad exposes all the methods (one way
 or another) and at the end you just call one method on the window
 object to indicate that the API is ready to be used. So you JS code
 just needs to wait until that method is invoked before starting

 If you want to use multiple GWT APIs this way, I guess the best thing
 to do is to have one onModuleLoad that invokes the injection of all
 the APIs in JS and then call one callback to kickstart your
 application. The idea of GWT is that you compile everything in one
 application to improve optimisations and to have a small as possible
 JS.

 Why  is the GWT API not fully initialized ? Well because it is
 actually loaded by a hidden IFrame. Additionally with GWT 2.0 we will
 be able to actually load parts on demand through runAsync support.

  Not this:

  Big deal right? ...but imagine how it scales. Say you depend on three

  myReallyActuallyReallyReadyFunction() {

  Ouch.

  I still don't understand why the onModuleLoad kicks off after the

  I suppose that vaguely makes sense, but it means that as an API

His,

In GWT 1.5 one needed to put images under public directory, with gwt
1.6/1.7 the recommended location is somewhere under your war
directory. I use normal images as well as ImageBundle in my project.
Could someone please clarify where image bundles are supposed to go

GWT and CMS - Integration problem with SOA

2009-08-10 Thread dstefanox


I am working on a project which requires integration of the CMS
(Drupal, almost certainly) and the GWT. Since GWT files in my case
should be served by Tomcat and CMS pages by Apache server, Same Origin
Policy problem occurs. Configuration is the following (for feasibility
experiment):
- Page into which GWT app is embeded is served by Apache web server:
http://localhost/SOP/PHPSOP/TestSOP.html
- This page includes Java Script and CSS which are served by Tomcat,
and which are actual GWT application:
http://localhost:8080/testsop/testsop.nocache.js
Inclusion example:
 script type=text/javascript language=javascript src=http://
localhost:8080/testsop/testsop.nocache.js/script
Note that here we use port 8080.
When page loads, following error occurs:

Permission denied for http://localhost:8080 to get property
Window.document from http://localhost.
http://localhost:8080/testsop/E00BCFA70A4A65848519BCCCE10E89FF.cache.html
Line 1

I know that if I use Apache web server to serve all files, this would
not happen, but I wonder, is there a way to make it work this way?

If I use Apache server to serve all files - main page into which GWT
app embeds and GWT files, this problem does not occur. In this case, I
have url like:
http://localhost/SOP/TestSOP/war/LocalSOP.html
JS is included as:
script type=text/javascript language=javascript src=testsop/
testsop.nocache.js/script
Application is loaded, and at this moment we do not have the problem.
But when I want to make RPC call from my application, GWT creates URL
for RPC call:
http://localhost/SOP/TestSOP/war/testsop/greet
Of course, this URL does not exist on my server. Actually, good URL on
which Tomcat would respond would be:
http://localhost:8080/testsop/greet
How can I make my application served by Apache on one URL to call RPC
managed by Tomcat on other URL? Please note that having Apache and
Tomcat at same time is MUST, so don't try to explain how other
configuration would work perfectly...

Hello Dejan,

You could have Apache act as the front server and forward all requests
to a specific URL to a tomcat server, have a look at [1]. This way
they both share the same server and port for an external visitor.

Re: Inlining nocache.js

2009-08-10 Thread George Georgovassilis


The way to do it finally was:

1. inline nocache.js as a script.../script in the module html
2. replace all string references of 'xyz.cache.html' to 'path/to/gwt/
output/xyz.cache.html'
3. (for RPC only) copy the serialization policy files to the module
html location

On Aug 4, 9:02 pm, George Georgovassilis g.georgovassi...@gmail.com
wrote:
 So, while trying to squeeze out the latest tiny bit of speed for my
 application I ended up with this setup:

 index.html ( = module page) contains inlined css and the nocache.js.
 The index.html is non-cacheable, but is guarded with an E-Tag, which
 doesn't do anything to first time users, but recurring users will see
 a 304 (not modified) and the application will load instantly. I
 inlined the CSS so that no further HTTP request is neccessary, the
 same rationale goes for the inlined nocache.js

 So the only HTTP requests are:
 1. load the index.html
 2. load aspriteimage
 3. load the browser dependent *.cache.js

 The problem here is that since I inlined nocache.js, now index.html
 has to reside in the same location with *.cache.js, which is horrible
 to configure for caching since I'm not using Apache but just Tomcat.

 Using a base href= to bend the base location seems to work only on
 Firefox, IE can't find its RPC services and Safari won't load at all.

 Any ideas?

Hi David,

thank you for sharing your solution. I had hoped that there is another
possibility. I have two questions about your solution:

1. How would you load a sub application without using an iframe?
Wouldn't there be a clash between the main application and the sub
application because the JavaScript of both parts would reside in the
same window object?

2. Can you please give me some more information about how you enabled
the communication between the applications. I can imagine a global
JavaScript object that registers and informs listeners of application
events.

 This file can make it so that...as far as gwt is concerned...the /

Re: At new item to a list at each position

I don't really need to know how to create the Array. I already created

Re: How to split a large application?


On Mon, Aug 10, 2009 at 2:23 PM, Stefanstefan.wach...@gmx.de wrote:

 Hi David,

 thank you for sharing your solution. I had hoped that there is another
 possibility. I have two questions about your solution:

 1. How would you load a sub application without using an iframe?
 Wouldn't there be a clash between the main application and the sub
 application because the JavaScript of both parts would reside in the
 same window object?

When I was talking about running without an IFrame I meant that my
application would not use an IFrame for display purpose.

GWT still uses an IFrame to load and separate the actual application
code. At a certain point my main application creates a DIV tag in the
root page and gives the ID to the subapplication to render in the DIV
tag.


 2. Can you please give me some more information about how you enabled
 the communication between the applications. I can imagine a global
 JavaScript object that registers and informs listeners of application
 events.

Yes indeed, that is basically what I've done. First of all, the main
application put a JS object on the DIV block which the application
will detect when starting. When the application is ready it calls a
method on this JS object to notify the main application that it is
ready. This way I can setup 2 way communication. So the application
can listen to events from the main app and the main app can also get
events from the sub apps.

The API between these 2 application is very limited. I actually use
JSON to encode/decode the messages since the Java-JS compiler
obfuscates the actual objects.

Re: GWT RPC

Fred,I have tried transferring a JDO enhanced class from server to client,
to no avail. The error I get is the same as before:

 Let me know how it goes with the latest plugin and GWT 1.7.0.
 Just to be clear, JDO enhanced classes still won't pass round trip, even if
 they are in detached state. For that you still need to transfer some sort of
 DTO between client and server. However, if you just want to take a JDO class
 and transfer it one way, you can sort of get that to work.

 Some of the annoyances have been cleaned up. The latest plugin takes care

 The biggest thing left is how to deal with detachable 'bytecode enhanced'

 been discussed at length on the GWT user + contributor forums. I think some
 good work is happening in this area to make life easier.

There are some incompatibilities between Eclipse's Dynamic Web Projects, and
applying the GWT Nature to these projects. When we wrote the plugin, we did
not explicitly try to integrate with Eclipse's J2EE support. However, a few
people on here have figured out a way to make the two work together. See the
following link for more information:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/39e0ff6325e4d504/55bfd342d77ec910

Keep in mind that when applying the GWT Nature, you need to create your
'war' directory first, and then apply the nature. If you did not do this,
you can correct the problem by removing the nature, applying the changes,
and then re-adding the nature. See
http://code.google.com/eclipse/docs/existingprojects.html for more
information.

If you're still stuck, post back here with the details (including extra
information, especially in the case of a GWT Compilation failure).

Server Root Directory


Hi,

in my initial client-server application I want to read a file, lets
say 'index.txt', which I then want to pass to the client as string.
Everything seems to be fine, however I get a file exception. So my
question is, what is the server root directory at run-time? I tried
several locations below 'war' but none of them helped.

So can you tell me the path where 'index.txt' has to be installed,
please?

How to import/require external Java Classes

use a class outside my project.client.*, e.g. a class from my

The Project's Java Build Path/Source does already contain the complete

definition for that or can this be done via Project Settings?

Re: How to import/require external Java Classes

2009-08-10 Thread Jason Parekh

Hi,
You'll likely run into issues trying to add your entire 'server' directory
as a source directory for GWT.  For example, this means each of those
classes needs to cleanly compile with gwtc, which may not be possible.

Instead, could you move some of the shared classes to the 'client'
directory?  The 'server' director can already reach files from the 'client'
directory (as seen with the default GreetingService example.)

Could you create a src/shared directory and add it as a source path=...
/ in your module XML?  This will keep it separate from client-specific code
and server-specific code, and both gwtc and javac will still be able to see
it.

If you want to create a brand new module for this shared code, you could do
that as well in a similar fashion (either put the shared code in the new

editable grids and listfields

2009-08-10 Thread Neil


Hi

I am trying to put together an application which uses an editable grid
to modify a data model. 1 field needs to be a drop down selection, and
another needs to be a multi-select. From what I can work out, the
listfield control will work for multi-select - however I have not
worked out how to hook it into the grid correctly, please could
someone give an example. I have had a search and have been unable to
find an example for this (but I may be looking in the wrong place!)

I have a simple data model e.g.

Model{
  int Id;
  string Name;
  int CategoryId;
  List role Roles;
}

the category Id will be populated from a drop down - displaying the
name not the id

category{
  int Id;
  string CategoryName;
}

the role is equally straightforward:

role{
 int Id;
 string RoleName;
}

how should I implement a multi-select list to edit the roles?

thanks for any assistance.

as a source directory for GWT. For example, this means each of those
classes needs to cleanly compile with gwtc, which may not be
possible.
EB: but this is a sub dir of the src dir - the later of which is
already included (by default)

It is a subdirectory of src, but GWT (by default) only looks to compile
the
files under src/client. JDK's javac is being used to compile the
src/server
files.

Instead, could you move some of the shared classes to the 'client'
directory? The 'server' director can already reach files from the
'client'
directory (as seen with the default GreetingService example.)
EB: sure, But this isn't an option as I wand to implement a clean
module structure.

Could you create a src/shared directory and add it as a source
path=...
/ in your module XML? This will keep it separate from client-specific
code
and server-specific code, and both gwtc and javac will still be able to
see
it.

If you want to create a brand new module for this shared code, you could
do
that as well in a similar fashion (either put the shared code in the new
module's src/client directory, or add whichever path you decide as a
source
path=... / in the module XML.)

Hi,

The Project's Java Build Path/Source does already contain the

 There are some incompatibilities between Eclipse's Dynamic Web Projects, and

 Keep in mind that when applying the GWT Nature, you need to create your
 'war' directory first, and then apply the nature. If you did not do this,
 you can correct the problem by removing the nature, applying the changes,
 and then re-adding the nature. 
 Seehttp://code.google.com/eclipse/docs/existingprojects.htmlfor more

 If you're still stuck, post back here with the details (including extra

Re: Will I have memory leaks if a Widget is removed from Panel without call to HandlerRegistration#removeHandler()

2009-08-10 Thread Arthur Kalmenson


I think that if you have handlers attached to a widget that gets
removed, it won't be garbage collected. There was a discussion about
this earlier here. I think if you hang onto the HandlerRegistration,
you can remove yourself onUnload().

 Now lets suppose that one of these widgets is removed from the panel
 without calling respective HandlerRegistration#removeHandler(). Will I
 have unnecessary references to the panel related to removed widget? Is
 it possible that this panel (as a Handler) will be invoked to handle
 an event (either native or logical) having removed widget as a source

Share instance between objects(DI)

2009-08-10 Thread Tercio


Hi!

I know that this isn't the correct forum for my question, as my
problem is related to Google-Gin, but it may be generic for sharing
instances problem.

I'm using Gin for dependent injection in my application, everything
works great, but I'm not able to inject the Injector instance into my
injected classes. hahaha sounds confusing... :-P

I use Google Guice in my servlets and the below snippet works great:
..

@Inject
public MyServlet(Injector injector)
{
  this.injector = injector;
}

...

My field this.injector will have a reference for the Injector that
injected it. I use it to create instances of classes that I need to
create more than once.

But Gin is unable to inject the Ginjector that injected the class.

Currently I created a public static field into my EntryPoint class
containing a reference for my injector, and I use this field
application wide. I think that it's not the best approach, as I'm
creating static dependents.

What is the best approach?

Thanks.

Re: At new item to a list at each position

2009-08-10 Thread Ian Bambury

Hi Tobe,
You seem to have changed from divs in the root panel to a widget, which is
probably the right way to go - depends on what you are doing, and you don't
say.

It does rather depend on how you are displaying things, and what you are
displaying. If there are columns (apart from the buttons) then are they
fixed-width or do they self-adjust? Are the items sorted in some way?

If you could give (even a theoretical) example of what this list consists
of, then it will be easier to answer. I suspect that the lack of response is
because people have too many possibilities in mind to comment

Instead of casting the results:   results = (ListCountry) query.execute();

you'll need to copy the results into the array. Note that you never actually
use this array:
   ListCountry results = new ArrayListCountry();

To see what I mean try this:
   final ListCountry results = new ArrayListCountry();

I'm still trying to isolate the code that causes this on my end, but I

Use of reserved words in JSON structure

2009-08-10 Thread Jeff Chimene


Hi,

I'm trying to implement an API that uses two JavaScript reserved words
in a JSON structure: public and private

Is there a clever JS technique to work-around this use of the reserved
word public?

Consider the following object

{addresses : {public: [],private:[]}

The following JSNI code fails missing name after . operator:

public final native ListString getPublicAddress() /*-{
return this.addresses.public;
}-*/;

public final native void setPublicAddress(String nextValue) /*-{
if (this.addresses.public.length = 0) {
this.addresses.public = new Array();
}
this.addresses.public.push(nextValue);
}-*/;

Re: sizing ListBoxes inside container

2009-08-10 Thread El Mentecato Mayor


AFAIK, there's no way to do that, it's a limitation or bug that GWT
has.  If you do this (set a visible item count larger to what you know
it will fit in the page), it will work on IE, but not on Firefox:

VerticalPanel ui = new VerticalPanel();
  ui.setBorderWidth(1);
  ui.setHeight(100%);
  ui.setWidth(100%);
  ListBox box1 = new ListBox();
  box1.setSize(100%, 100%);
  box1.addItem(item1);
  box1.addItem(item 1.1);
  box1.setVisibleItemCount(100);
  ui.add(box1);
  ui.setCellHeight(box1, 20%);
  ListBox box2 = new ListBox();
  box2.addItem(item 2);
  box2.setSize(100%, 100%);
  box2.setVisibleItemCount(100);
  ui.add(box2);
  ui.setCellHeight(box2, 20%);
  ListBox box3 = new ListBox();
  box3.setSize(100%, 100%);
  box3.setVisibleItemCount(300);
  box3.addItem(item 3);
  ui.add(box3);
  ui.setCellHeight(box3, 60%);

Maybe a way to accomplish this is to get the size of the window, and
then divide it in whatever percentages, and then set the size in
pixels for each listBox.  You'll also need to have a
windowResizeListener to resize the listboxes when the window size
changes.

Browser independent javascript without bootstrap code?

2009-08-10 Thread Haitao


Is there a way for GWT to generate browser independent script without
loading the bootstrap code first? I understand this will hurt
performance a bit. I am trying to insert the generated code into a
gadget. If the gadget only contains bootstrap code, then after I
update my app and before the gadget container updates its copy of
gadget XML all users will still try to load the old xxx.nocache.js
files which are already gone.

Netbeans in Histed Mode : cache problem ?

2009-08-10 Thread nicorama


Hi,
I used GWT with Eclipse, and now with Netbeans 6.7.1 with GWT4NB (I
usually much prefer Netbeans).

I change my Html code from :

 body
script language=javascript src=org.gwtimport.Main/
org.gwtimport.Main.nocache.js/script
/body

to :
 body
div id=bobBlablabla/div
script language=javascript src=org.gwtimport.Main/
org.gwtimport.Main.nocache.js/script
/body


In Web mode, it works. In hosted mode, the 'Blablabla' never apperas.
Everything was ok with the Eclipse, but at every change, the
datanucleus stuff was working.

I've seen nothing useful in the GWT4NB forums, so it's maybe not a
problem related to the plug-in - maybe it how I use GWT.

Thanks for your help,
Nicolas

Re: sizing ListBoxes inside container

It's nothing to do with GWT except that the VP is a table and the working
example is using divs.
Try something like this:

FlowPanel ui = new FlowPanel();
RootPanel.get().add(ui);
RootPanel.getBodyElement().getStyle().setProperty(margin, 0);

ui.setHeight(100%);
ui.setWidth(100%);

ListBox box1 = new ListBox();
box1.setHeight(20%);
box1.setWidth(100%);
box1.addItem(item1);
box1.setVisibleItemCount(100);
box1.getElement().getStyle().setProperty(display, block);
ui.add(box1);

ListBox box2 = new ListBox();
box2.setHeight(20%);
box2.setWidth(100%);
box2.addItem(item2);
box2.setVisibleItemCount(100);
box2.getElement().getStyle().setProperty(display, block);
ui.add(box2);

ListBox box3 = new ListBox();
box3.setHeight(60%);
box3.setWidth(100%);
box3.addItem(item3);
box3.setVisibleItemCount(100);
box3.getElement().getStyle().setProperty(display, block);

Re: Deferred binding for mobile browser support

Hi Michael,
If you could elaborate a little more on which part of deferred binding
you're not sure about, that would help pinpoint the problem you're having
and setup deferred binding code for your mobile browser target.

In general, however, the way deferred binding works is by defining the rules
for the deferred binding using replacement (see doc link below), creating
the default and the mobile classes that should be used for the desktop
browser and mobile browser versions of your widget, respectively, and then
creating your widget via the GWT.create(MyWidget.class) call to have the
compiler create bindings for the mobile target.

Deferred Binding using Replacement:
http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideDeferredBinding

For an example, check out the inner workings of the PopupPanel widget.
You'll notice that the PopupImpl instance belonging to the PopupPanel class
is created using the GWT.create(PopupImpl.class) call. Looking at the
deferred binding rules for the PopupPanel in the Popup.gwt.xml file
(contained in the gwt-user.jar), you'll see that the following rules are
defined:

  !-- Fall through to this rule is the browser isn't IE or Mozilla --
  replace-with class=com.google.gwt.user.client.ui.impl.PopupImpl
when-type-is class=com.google.gwt.user.client.ui.impl.PopupImpl/
  /replace-with

  !-- Mozilla needs a different implementation due to issue #410 --
  replace-with class=com.google.gwt.user.client.ui.impl.PopupImplMozilla
when-type-is class=com.google.gwt.user.client.ui.impl.PopupImpl/
any
  when-property-is name=user.agent value=gecko/
  when-property-is name=user.agent value=gecko1_8/
/any
  /replace-with

You could essentially follow the same pattern for the mobile version of
MyWidget.class, perhaps creating a MyWidget.gwt.xml file to contain the
deferred binding rules.

Hope that helps,
-Sumit Chandel

 Hi,

 I have to add a mobile-optimized version to an existing gwt

 binding is the technology of chioce. I believe I understand how it
 basically works but how do I use it in that specific use case?
 The mobile UI of our application differs a lot from the standard
 version so I need seperate stylesheets, and seperate GWT controls (we
 use composites a lot). Since the basic layout of our application is
 done in the .html file I would also need a separate html file.
 Now the question is: how do I do that? Are there any best practices?

 I'd really appreciate any hint.

Re: how to fetch multiple field from appengine datastore

Hi buzz_buzz,
You could create a lightweight data transfer object (DTO) that could contain
the information that you're interested in getting across the wire in your
RPC call. For example, the getStocks() method signature could be changed to:

public StockDataTransferObject[] getStocks() throws NotLoggedInException {
  ...
  ListStockDataTransferObject stockDTOs = new
ArrayListStockDataTransferObject();
  try {
...
ListStock stocks = (ListStock) q.execute(getUser());
for(Stock stock : stocks) {
  stockDTOs.add(new StockDataTransferObject(stock.getSymbol(),
stock.getOtherData()));
}

  } finally {
...
  }
  return (StockDataTransferObject[]) stockDTOs.toArray(new
StockDataTransferObject[0]);
}

  public String[] getStocks() throws NotLoggedInException {
checkLoggedIn();
PersistenceManager pm = getPersistenceManager();
ListString symbols = new ArrayListString();
try {
  Query q = pm.newQuery(Stock.class, user == u);
  q.declareParameters(com.google.appengine.api.users.User u);
  q.setOrdering(createDate);
  ListStock stocks = (ListStock) q.execute(getUser());
  for (Stock stock : stocks) {
symbols.add(stock.getSymbol());
  }
} finally {
  pm.close();
}
return (String[]) symbols.toArray(new String[0]);
  }


 its clearly the code only extract 1 field. how to extract another
 field.. Thanks

Button Focus on mac

2009-08-10 Thread Ana Maria


Hi!
I have a vertical panel with one textbox and 4 buttons and I want to
be able to use the tab key to change from one button to the other. I
tried btnName.setTabIndex(n); with n from 2 to 5 for the button
(textbox indextab=1). It doesn't work. I tried it in the hosted
browser, safari 4.0.1 and firefox 3.0.13. The focus is not set to any
button, and if I set it by clicking on one of them, when I press tab
the focus goes to the browser navigation elements and then to the
textbox , never to the buttons.
I'm using gwt 1.7 with Mac X 10.5.7
Is this a Mac problem? are there any know solutions?
Thanks

Multiple GWT Entry Points with URL Filtering

2009-08-10 Thread davis


Hi, I searched the group on this topic, and read some posts where
people had questions on how to do this.  I'm not sure I've discovered
the *best* way, but I think I found a way that works pretty well.

As an example, this is useful if you want to have a separate GWT entry
point for an Admin application that is hosted at a different URL.

I posted the details on my blog: http://zenoconsulting.wikidot.com/blog:16

...with a sample maven project that can be used as a skeleton.  Hope
someone finds it useful.

combo.setEmptyText(Select a Country...);
combo.setDisplayField(value);
combo.setStore(countryStateStore);   //At this Stage the Store

//I do not want to push the the following 2 line of code in the

vp.add(new HTML(SELECT Country LIST));
vp.add(combo);//

Vp : Vertical Panel . I think this is what is happening , maybe even
before the async Value is returned , these two lines of code are
drawn . At this point the combo box gets painted with maybe empty
store . Maybe I am wrong .




vp.add(new HTML(SELECT FAVORITES LIST));

Re: decide zoom level from multiple points

thanks for your hint, i will use getBoundsZoomLevel()

LatLng point2 = LatLng.newInstance(maxLatitude, maxLongitude);
double distance = point1.distanceFrom(point2);
int zoomLevel = new GZoomLevels().getZoomLevelForDistance(distance);

public class GZoomLevels {
ListInteger meters = new ArrayListInteger();

public GZoomLevels() {
meters.add(1000); // 0
meters.add(500); // 1
meters.add(300); // 2
meters.add(200); // 3
meters.add(100); // 4
meters.add(50); // 5
meters.add(20); // 6

if (meters.get(i) = distandeInMeters.intValue()) {
zoomLevel = i + 2;

[gwt-contrib] Re: insertPanel interface

2009-08-10 Thread Miroslav Pokorny


It's a difficult juggling act, balancing the need to have interfaces  
fir everything and the practical value in actually doing it. I recall  
rwading/listening to something Josh Bloch said about why there are not  
any read only collection interfaces Vs the way it was done and what we  
have today. Why do I bring this up - mainly because there are  
similarities in both cases. It's not always a good thing to have  
interfaces describing all contracts for a panel, just like perhaps it  
didn't make sense to have UnreadableList etc...

Unfortunately writing code is about these sorts of nuances - I like to  
think of them like the annoying mozzies one gets in the summer.  
Summer, the beach etc are all great ( like gwt) but sometimes there's  
a mozzie buzzing around.

 Hi  Miroslav
 Thanks for the feedback.
 You make a good point there about the increase in the amount of

 I wasn't aware of that and would love to hear about this.

 It makes you wonder what is better. I mean: using these interfaces
 also safes code as I can re-use code that works agains different
 implementations, I think it's better progamming,  overcomes code
 duplication and reduces bugs...  But at the other end the amount of
 code increases...

[gwt-contrib] Re: New GWT RPC project: gwt-rpc-plus

2009-08-10 Thread Matt Mastracci


David,

The new RPC framework in the library currently suffers from the  
reference limits of Thrift itself, which are 'no self or forward  
references'.  This effectively limits the object nesting depth.  
Additionally, all the de/serialization is done via native primitives  
which seem to handle larger structures well.

You don't necessarily have to use Thrift here. I do have some old code  
(which hasn't been imported here yet unfortunately) that generate  
client side API stubs that can receive standard API calls made by  
other client code. I'll dig it up and unrot it. I had completely  
forgotten about that code until now. By pairing the code with a cross  
module transport (function call, postMessage or location hash), you'll  
be able to communicate between two modules using code that looks  
identical to standard RPC.

 Matthew,

 Now you got me interested! I currently have some JSNI code to

 Can your RPC library handle complex structures (where the current 1.x
 GWT RPC layers gives stackoverflow or out of memory) ?

 David

 Note that we'll be doing some cool stuff with our library in the
 future that we can't easily do with GWT RPC, like generating raw
 Javascript bindings for third-party developers to interface with our
 API and using it for module-to-module cross-domain communication.

 I was just wondering if it were possible to specify a concrete

 for an interface type - this would this help solve the too many

 generator to create Serializers for all concrete types  
 implementing List
 etc.

 Service {

@Annotation(java.util.ArrayList.class);
 ListType method( int parameter );

 }

 In the above case no matter what type of List the server sent, the  
 client
 would always get an ArrayList.

 Naturally the same annotation would appear on value types with List
 properties. Perhaps something similar could be used to whitelist  
 sub class
 serializer generation.

 matt...@mastracci.comwrote:





 Bart,

 One principle of design for the alternate RPC framework in this
 library was reducing the number of non-JSO classes generated in the
 final output, at the expense of developer convenience and
 flexibility.  At one point, RPC classes and serializers were  
 nearing
 20% of our compiled output.

 By reducing some of the flexibility of RPC (ie, with machine built
 overlay types and collections that implement just enough to get  
 by),
 we can effectively reduce the RPC footprint in terms of wire size,
 code size and serialization/deserialization time.

 Note that bobv's direct-eval RPC branch should come with its own
 significant performance gains and code/wire size reductions. It  
 may be
 worth investigating the performance of trunk for your specific  
 case as
 well.  Of course, if GWT RPC is sufficient for your use, you can
 always use this library to add cross-domain transport of RPC  
 payloads
 or add out-of-band context to the request/response data.

 I'd be interested in hearing any thoughts or suggestions you  
 might have.

 Thanks,

2009-08-10 Thread Amir Kashani

Joel,
I love how this is turning out so far, great work. While this system handles
a vast majority of layout situations, correct me if I'm wrong, but I think
it breaks down with non-100% height layouts that require a footer. An
example: a header area, followed by a horizontally split content area (body
and side nav), followed by a footer. I can't think of a way you could
represent this using absolute positioning that would guarantee the footer
area isn't encroached upon.

Any thoughts on how LayoutPanel would handle this? Maybe this doesn't fall
under desktop-like layouts and it's handled with floats (which aren't so
terrible in this particular case)?

[gwt-contrib] Re: Extending ValueChangeEvent

2009-08-10 Thread Joel Webber

I wasn't directly involved in writing these classes, but having each
subclass' getAssociatedType() be final seems a bit overzealous to me. If you
want to subclass it (which doesn't seem unreasonable), it seems like you'd
*need* to override this method.
@Ray, John: Do either of you recognize any obvious utility in making this
method final? If not, I think it should be made non-final across all event
types.

 Why is the getAssociatedType() method on ValueChangeEvent considered
 final? I'd like to be able to extend this event, but I can't extend it
 if I can't override getAssociatedType().

 Let me explain:

 I'm writing a module that is designed to be a base for a slew of other
 expanded versions of the module, keeping much of the core
 functionality locked up in a core module and expanding as necessary
 through additional modules.

 To be specific, this is a video player module, so some core events
 might be PlayEvent or ValueChangeEvent when the currently playing URL
 changes. Those events should always be generated by the core, but add-
 on modules should be able to respond to those events.

 In order to prevent the add-on modules and core components from
 needing to know about each other and adding ***Handlers to all the
 various Has***Handlers in the application, I created a central
 Dispatcher that can register and fire any events - a sort of global
 event bus for all events to come in and get dispatched from.

 It works well, but because ValueChangeEvent is generic, I can only
 implement HasValueChangeHandlers for one type on my central
 dispatcher. As it turns out, I need at least two types, and Handlers
 are only interested in one or the other.

 To register for the right event, I coded this:

private static MapInteger, Object TYPES = new HashMapInteger,
 Object();

@SuppressWarnings(unchecked)
public static T TypeModelHandlerT getType(ClassT clazz) {
Integer key = clazz.hashCode();
if (!ModelChangeEvent.TYPES.containsKey(key)) {
TypeModelHandlerT type = new
 TypeModelHandlerT();
ModelChangeEvent.TYPES.put(key, type);
}
return (TypeModelHandlerT)
 ModelChangeEvent.TYPES.get(key);
}

 So you can register for ValueChangeEvents pertaining to a given class
 type.

 However, I need to override getAssociatedType() to do the following:

@SuppressWarnings(unchecked)
@Override
public TypeValueChangeHandlerT getAssociatedType() {
// TODO: Add null check
Integer key = getValue().getClass().hashCode();
return (TypeValueChangeHandlerT)
 ModelChangeEvent.TYPES.get
 (key);
}


 So this limits my ability to reuse the ValueChangeHandler on a more
 global scope without copy/pasting the class... Unless I am just
 completely distorting the point of the new 1.6 event system...

[gwt-contrib] Re: Extending ValueChangeEvent

2009-08-10 Thread John LaBanca

I believe the problem is that if you extend ValueChangeEvent and
ValueChangeHandler, you can then call
Widget#addHandler(mySubValueChangeHandler, ValueChangeEvent.getType()),
creating a mismatch because you are associating a SubValueChangeHandler with
the ValueChangeEvent type.  While I don't think this will cause technically
any problems, it can lead to a little confusion because if you fire a
SubValueChangeEvent, your handler will not fire.

Still, I think we can just javadoc that and take off the final modifier.

 creating a mismatch because you are associating a SubValueChangeHandler with
 the ValueChangeEvent type.  While I don't think this will cause technically
 any problems, it can lead to a little confusion because if you fire a
 SubValueChangeEvent, your handler will not fire.

 Still, I think we can just javadoc that and take off the final modifier.


This could be useful in that you could register a change handler that takes
a superclass event, and register it for some number of specific subclasses
that you want to handle.

Ideally, there would be a way to register a handler for all subclasses as
well, ie:

  addHandler(ValueChangeHandlerFooSuper handler, FooSuper.getType());

and it would get triggered on FooSub1, FooSub2, etc as well.

[gwt-contrib] Proposed API Addition - GWTTestCase#getStrategy() to allow precompilation of JUnit tests

2009-08-10 Thread John LaBanca

Background:
=
Currently, Junit tests and module compilations run synchronously as follows:
1. Compile the first module
2. Run tests in first module
3. Compile second module
4. Run tests in second module
5. Continue through all modules

Since running tests can be time consuming but requires very little CPU, I'd
like to compile future modules while tests are running.  That is:
1. Compile the first module
2. Run tests in first module while compiling  second module
3. Run tests in second module while compiling third module
4. Continue through all modules

This has two advantages.  First, it parallelizes test runs  and compiles,
allowing the tests to run a little faster.

Second, by pre-compiling all modules, we don't have to synchronize remote
clients, which means faster clients can run to completion before other
remote clients connect.  For example, if you have 5 test systems running
selenium or BrowerManager, the first system can run the tests and return
immediately before the other 4 connect, which has some advantages in terms
of reducing usage of test machines.  Without this change, the first system
has to wait for all systems to sync up before running the next module.


API Change:
=
The problem is that JUnitShell creates a synthetic module name based on the
JUnitStrategy.Strategy that is passed into JunitShell#runTest() when the
test is run, which means we can't compile the next test module until the
next test starts because we don't know the synthetic module name.  I propose
that we add the method GWTTestCase#getStrategy() that will be used when we
populate GWTTestCase#ALL_GWT_TESTS.

Currently, we assume the synthetic module name just adds .JUnit to the
module name, which is true for almost all GWT test cases.  However, test
cases that extend Benchmark use a different strategy and a differnet
synthetic module extension.  Presumably, other developers may be doing
something similar.  By adding the following method to GWTTestCase, we can
use the correct synthetic module name when grouping test cases together in
GWTTestCase#ALL_GWT_TESTS.

public JUnitShell.Strategy getStrategy()

GWTTestCase will return JUnitShell.JUnitStrategy (which will be made public
and final).  Benchmark, the only class that uses a different strategy in the
GWT codebase, will return a private inner class called BenchmarkStrategy.
GWTTestCase#runTest() will pass the strategy into JUnitShell.runTest()
instead of letting JUnitShell use the default one.


Who this affects:

This change affects a very small set of developers who actually override
GWTTestCase#runTest() and manually call JUnitShell with a strategy option.
They will need to ensure that their test case returns the correct strategy,
or it won't run as part of the correct synthetic module.



Deprecation and further changes:
=
Since JUnitShell is meant for use with GWTTestCases, I also propose the
following to avoid a situation where the return value of
GWTTestCase#getStrategy() does not equal the strategy passed into
JUnitShell#runTest().


The following methods will be deprecated:
JUnitShell#runTest(String moduleName, TestCase testCase, TestResult
testResult)
JUnitShell#runTest(String moduleName, TestCase testCase, TestResult
testResult, Strategy strategy)

And this will be added:
JUnitShell#runTest(String moduleName, GWTTestCase testCase, TestResult
testResult)

Since GWTTestCase will provide the strategy, we no longer need to pass it
in.

Thanks,
John LaBanca

[gwt-contrib] How to enable web mode debugging in GWT

2009-08-10 Thread Joy


Hi All,

I can see hosted mode debug message in eclipse console. When I compile
and run mt application in IE I get some javascipt error messages. But
I am uanble to debug because I am not getting the culprit java file
which might have caused the error.

So I want to know how to enable web mode debugging, so that i can see
the java stack trace in eclipse console, while running the application
in IE.

Thanks in advance.

[gwt-contrib] DTO compiler optimization

2009-08-10 Thread Nathan Wells


I have hesitated to bring this up, since I'm relatively new to GWT,
and I would hate to waste anyone's time with explaining what is
hopefully common knowledge to me.

Specifically, I thinking about the DTO problem. I think the general
opinion about DTOs is that they are a necessary evil when working with
GWT. And let me say, they are a very minor blemish on a life-saving
framework. But, It seems to me that the problem has a more elegant
solution. I would propose that all we need to do is increase the
granularity of GWT compiler control.

For clarification, I would like to be able to tell the compiler at the
class member level (either through annotations or *.gwt.xml) what
should be client-side and what should be server-side. As an example,
compiling the following class wouldn't be a problem:

class Foo implements Serializable {

  @ServerOnly
  static long serialVersionUID = 325490285;

  //default, of course compiles to java byte-code and js.
  String bar;

  @ServerOnly
  void setBar(String bar) {
//a method which might reference un-emulated JRE classes
  }

  String getBar() {
return bar;
  }

}

I hope that makes sense... that way, our the same class could be used
on server and client side. Hurray for OO!

Again, I'm sure there are some unforeseen consequences of this design,
not the least of which is the possibility that it would require
basically rebuilding the GWT compiler. I'm just hoping that this
discussion might answer other n00b questions in the future :)

[gwt-contrib] move SOYC source code underneath dev/core/src

2009-08-10 Thread spoon


Reviewers: fabbott,

Description:
This patch moves SOYC's source code underneath dev/core/src.  It leaves
gwt-soyc-vis.jar existing and containing the SOYC static resources (css
and gifs).  It has gwt-dev-platform.jar also contain the SOYC static
resources.

The goal is to phase out gwt-soyc-vis.jar.  After this patch, existing
build rules and scripts should  keep working, but it should also
possible to drop all references to gwt-soyc-vis.jar.  The references can
either be dropped outright (as in a classpath) or replaced by a
reference to gwt-dev-platform.jar (as in the -resources argument to
SoycDashboard).

[gwt-contrib] Add a tab key to wire protocol

2009-08-10 Thread jat


Reviewers: amitmanjhi,

Description:
After talking with Miguel, it became obvious that we want the ability to
show tabs in the plugin which correspond to tabs in the browser.  Right
now, we don't have the ability to get that information in the browser,
but I am adding the wire protocol support for when we do.

[gwt-contrib] Re: Initial implementation of layout system, along with the first two layout widgets.

2009-08-10 Thread Kango_V


Amir, this is the exact case I am working on.  I'm trting to implement
an interface not dissimilar to Google Reader.  It has a footer at the
bottom of the grid for next prev buttons.

Can this layout handle this?

Excellent work as always.  I'm keenly following this.  Can't get it
quick enough :)

On Aug 10, 9:26 am, Amir Kashani amirkash...@gmail.com wrote:
 Joel,
 I love how this is turning out so far, great work. While this system handles
 a vast majority of layout situations, correct me if I'm wrong, but I think
 it breaks down with non-100% height layouts that require a footer. An
 example: a header area, followed by a horizontally split content area (body
 and side nav), followed by a footer. I can't think of a way you could
 represent this using absolute positioning that would guarantee the footer
 area isn't encroached upon.

 Any thoughts on how LayoutPanel would handle this? Maybe this doesn't fall
 under desktop-like layouts and it's handled with floats (which aren't so
 terrible in this particular case)?
