You're not setting the Content-Type of the request payload, and servlet 
containers generally only decode request payload that are explicitly 
identified as application/x-www-form-urlencoded.

In your doPost, you should add a builder.setHeader(Content-Type, 
application/x-www-form-urlencoded) before the call to 
builder.sendRequest().

(and thanks a lot to the new Google Groups for offering an inline

Re: Refreshing reference message and eclipse extremely slow

2010-12-23 Thread Jerome C.

Any news about this ?

It really slows down development...

What's the reason ? Is it client bundle or not ? Is there something which 
should not do to avoid this performance bug ?

9 peoples have starred it, so I'm not the only one. 

I've tried to find release note of the last version of Google plugin (1.4.2) 
but the release note page is not updated. With the last version of the 
plugin, the problem stays the same.

Thanks.

Re: Modular rpc blues

2010-12-23 Thread Coelho

I checked the content and I have the servlet tag in a the module descriptor
( Check the contents of the .jar file. Does it contain the module 
descriptor? Does the module descriptor contain servlet tags for the RPCs? )

I wonder if it is not a matter of gwt-maven-plugin version
because the all sample compiles once and the version was 1.3-SNAPSHOT , if my 
memory is not failing

then I had compilation problems ( not with thi project I think )
so I cleared my maven local repository
then from this moment on It complained about 1.3-SNAPSHOT that could not be 
found
so I changed to 2.1.0-1


this morning I reversed back to 1.3-SNAPSHOT : it compiles again ! an runs

why not with 2.1.0-1 ?

Thanks for reading

  Alright, now I get it!



  To bundle RPC functionality in a reusable (.jar) GWT module you only need 
to declare any RPC servlet in the module's module descriptor. That's all. 
gwt:mergewebxml will create appropriate servlet mappings in the target 
web.xml. It's really that easy.


  Make sure the .jar really  contains the module descriptor (*.gwt.xml) and 
that the RPC servlets are actually declared in it. If you try it with a module 
that used to be an application and only declared its RPC servlets directly in 
its web.xml you won't be able to use them via gwt:mergewebxml AFAIK.

  Another question just coming to my mind: 


  Where in the inherited module are you declaring the RPC servlet?


  If you declare it in the inherited module's web.xml then make 
sure the Maven GWT plugin parameter webXml properly points to it (Not sure 
how one would do this - never did it myself - especially since  inherited 
modules usually come as a .jar. If so does yours include the web.xml?).

Re: 2.1 MVP and handlers



On Thursday, December 23, 2010 3:38:12 AM UTC+1, sunny...@gmail.com wrote:

 Hi everyone, 

 Before 2.1 I created an application that use the old MVP 
 architecture of having models, views and presenters. This worked quite 
 well. I'm migrating this application to use the 2.1 MVP framework now. 
 I've made some progress but am still getting my head around it. 

 This has hit me so far: in my old code, the presenter was responsible 
 for setting the listeners/handlers on the view/eventbus respectively. 
 Where appropriate handlers would be removed when the view changed so 
 that events are not handled more than once. (eg, I destroy my login 
 window once login succeeds, and I also remove the eventbus 
 LoginSucceededEvent handler, so after logging out there aren't two of 
 them listening on the eventbus) 

 Here is the start method of the apps' login activity: 
 @Override 
 public void start(AcceptsOneWidget panel, EventBus eventBus) { 
 LoginView view = clientFactory.getLoginView();  // just one instance 
 bindView(view);   // eg, view.getButton().addClickHandler(... 
 bindEvents(view, eventBus);   // eg, eventBus.addHandler( 
 panel.setWidget(view.asWidget()); 
 } 

 The LoginView is reused from the ClientFactory as the documentation 
 suggests. This raises two questions: 

 1) I would like to keep the GUI bindings outside the UI code (just as 
 I did in the old code where it was in the presenter). But since the 
 documentation suggests using a single instance of a the views, here I 
 would be adding more and more listeners each time the activity is 
 initialised (as they are in the ActivityMapper). The HelloMVP example 
 has the binding code in the view and allows the view to communicate 
 with the activity. Can this be avoided? It would help in keeping the 
 UI code strictly to UI and presentation. Short of implementing a 
 method on all views that clear its listeners I cannot think of a 
 better way (I would still think this to be cumbersome - its not 
 something you'd normally do)


First, you have to understand the why of this suggestion: everything 
DOM-related is slow. This means that creating a view is slow (compared to 
creating any other POJO, such as your presenters/activities).
Having initially worked with the HasXxxHandlers approach (MVP tutorial - 
part 1) and later switched to the delegates approach (quite some time 
before the MVP tutorial - part 2 and places  activities tutorials were 
written), I assure you that writing unit tests is wy easier with the 
latter ! (I also find the presenter code more readable, and it allows using 
@UiHandler methods in your view if you use UiBinder). If you want to make 
the switch, I assure you you won't regret it.

That being said, you're not forced to do the switch. If you want to keep 
your addXxxHandler calls in your presenter, then you'll have to remove them 
when the activity is over. This means keeping a reference to every 
HandlerRegistration returned by the addXxxHandler calls, and call 
removeHandler in each one from the onStop and onCancel methods of the 
activity.
Someone posted (a few months back, maybe it was even last year) a 
HandlerRegistration holder, where you add your HandlerRegistration objects 
(e.g. holder.add(view.saveButton().addClickHandler(...)), so you only have a 
single call to holder.removeHandlers() in your onStop/onCancel. This is an 
approach that has been used by MVP frameworks such as gwt-mvp and 
gwt-platform too (but I don't think it's re-usable outside those 
frameworks).
 

 2) Similar issue with eventbus handlers - I can't wrap the eventbus in 
 a ResettableEventBus as I don't want to wipe all handlers off the 
 eventbus, nor do I want to have to manually deal with each handler in 
 onStop of the Activity.


As Y2i said, this is actually not an issue as the EventBus you get passed in 
onStart *is* a ResettableEventBus.

I don't understand why the ResettableEventBus is an issue for you though… 
(activities are meant to be thrown away once they're stopped/cancelled, 
they're specifically not meant to be re-used)

Re: GWT Tomcat 404 error RPC www.domain.com

2010-12-23 Thread Basdl

Your first link contains the path /domain therefore the RPC includes
this path in its call.
Your second call misses the path /domain.
I guess www.domain.com/domain should work for you.
You may make a redirect from www.domain.com to www.domain.com/
domain or redefine your servlet-mapping.

Hope this helps you,

Re: How to force Spring to intercept RequestFactoryServlet

Thank you for your feedback and support on this.

I spent a very long time, trying many different combinations,
including those you suggested, unfortunately none of them worked.

this topic was also discussed here, you can see my comments there.
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/20ea2aea53aa29d3

here is the log, showing whats going on ...
http://paste.pocoo.org/show/308797/

based on your suggestion, I removed references to
RequestFactoryServlet from web.xml
and added this mapping to my webmvc-config.xml config file:

bean
class=org.springframework.web.servlet.handler.SimpleUrlHandlerMapping
property name=mappings
value/gwtRequest=gwtRequestFactoryController/value
/property
/bean
bean id=gwtRequestFactoryController
class=com.google.gwt.requestfactory.server.RequestFactoryServlet/

from the log file, it is clear that /gwtRequest is mapped.
I also tried dozen of other combinations, but unfortunately no luck.

still don't know why GWT RequestFactoryServlet behaves like this in
Spring configured environment ?

Weird EOF Exception while trying to download file from GWT application

2010-12-23 Thread tarun

Hi,
I am trying to download a file from GWT client. At server side there
is a servlet which generates content of file as per request and send
it back to the client.

Test Scenarios:

Scenario 1 If I hit url of servlet directly, it always give me desired
result without any problems.

Scenario 2 Using GWT client on IE8,I am able to download file without
any code changes. However on some other computer as soon as I try to
write file content on response output stream, I get EOF exception.

org.mortbay.jetty.EofException
at org.mortbay.jetty.HttpGenerator.flush(HttpGenerator.java:760)
at org.mortbay.jetty.AbstractGenerator
$Output.flush(AbstractGenerator.java:566)

110)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:
717)Creating input stream


Code of servlet is as follows:


try
{
output = new BufferedOutputStream(response.getOutputStream(),
DEFAULT_BUFFER_SIZE);
byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
int length;
int bytesWritten=0;
while ((length = data.read(buffer))  0) {
bytesWritten+=length;
output.write(buffer, 0, length);
}
output.flush() // At this point I am facing EOF exception.

where data is inputStream

Via means of bytesWritten variable I have confirmed that in all the
three scenarios content has been written in the same way in output
stream. But not sure why it is not working in some computers.

Any pointers will be highly appereciated.

course) I realized that this approach is inappropriate for my application.
The reason is that my application is basically modeless - meaning that I can
remove a widget from the dom and hold onto the widget object via a
reference, replace the widget in the dom with another widget and at some
future time restore the widget that I removed.

Here's a use case for such a scenario: Composite A which is a singleton is
created and once attached to the dom it will remain attached for the
lifetime of the application. Composite A is a view of a list of data models
and when the user selects a data model to edit from the list Composite A
hides itself and then shows a sub view which is Composite B that allows
editing of the data model's attributes. Composite B has numerous list box
widgets that contain values that can be created from other Compsosite views
in the application. At some point the user needs to select a value from one
of these list boxes but the value doesn't exist so the user switches to a
different view, Compsite Z, which replaces Composite A by removing it from
the dom and inserting itself into the dom. While in Composite Z's view the
user adds a new value. Once she saves the value Composite Z will fire off an
event notifying that a new value now exists which Composite B handles even
though at the time it handles the event it is not attached to the dom. The
user then switches back to view Composite B which replaces Composite Z by
removing it from the dom and adding itself back to the dom and in the list
box the user now sees the new value which Composite B added to it when it
handled the event that Composite Z had fired.

As the above use case demonstrates, my application is extremely modeless and
is very similar to a desktop application in that regard. In order to get
onUnload to work for my use case required that Composite B check a boolen
attribute which is only set to true when the user actually closes Composite
B which sets the boolean to true and if true actually calls removeHandler.

Do you think the current GWT implementation of MVP would be appropriate -
meaning would it be able to handle my use case of using modeless views as
described above?

Thanks in advance,
Jeff

Re: Centering an image in a SimplePanel

2010-12-23 Thread Jeff Schwartz

If you were using pure css to do this your outer container, a div, would
have a width and the inner element, in this case an image, would set its
left and right margins to auto causing the image to be vertically centered
within its outer container.

Try implementing the above using GWT semantics and it will work. If you are
using UiBinder this is easy because you can attach the styles directly to
your HTML tags either as styles or classes.

Re: Compressing JSON?

2010-12-23 Thread Miroslav Genov


Are you sure that you have to transfer such amount of data to your client ?

Have you considered some kind of data separation or maybe some 
pagination technique ?  If you are returning so much data, this means 
that your users have to look into that data, which in most cases takes a 
lot of time.

There are situations when my JSON gets bigger and it causes a delay in

would that be any helpful?

Re: Compressing JSON?

2010-12-23 Thread ?mit

Well I agree with mgenov. For tables and lists you should really consider 
only transferring data which is actually displayed. 
However sometimes this is not possible. 
For example in one of my applications I have to display around 50.000 dots 
in a 5 different scatterplots. My backend (cherrypy, python webserver) 
creates a google visualization datatable (json array) which is passed to my 
GWT application. 
The response of this json array is around 330 kb in size. It's acutally fast 
enough to display it quickly. However by enabling gzip compression on the 
webserver I could reduce the response size from 330 kb to around 110 kb.
That's actually quite significant. For these kind of use cases 
I definitely recommend to activate gzip compression on the server.

Re: Compressing JSON?

2010-12-23 Thread shahid

I agree and I do have pagination where I can possibly do so. The
problem arise when I have for example a large form with data that
should be populated in or the amount of data I am displaying on one
screen itself is big enough e.g. in the case of showing trend data
over a period of 4 weeks for example.

Why you have to render trend on the client side ?

You probably could ask the server to render graphic as image, then you could 
render it using Image widget ?

This is just an idea, I don't know whether this is possible in your case.

Confused about Servlet mapping and Url Pattern, RPC not working when Deployed

2010-12-23 Thread AmaraSat

I have implemneted the example Stock Watcher application, i am trying
to deploy the example in Apache Tomcat 5.5.

After downloading the example from GWT @
http://code.google.com/webtoolkit/doc/trunk/tutorial/RPC.html, and
implementing GWT RPC according to the tutorial:

I haven't come across setting the servlet mapping in the Tutotrial.
After deploying in Apache Tomcat 5.5, only my client side code is
running and its not connecting to the server side.

After reading this from the tutorial

If your web pages display but the RPC calls don't seem to be going
through, try turning on access logging on Tomcat. You may find that
the URL used by the client side has not been registered by Tomcat, or
that there is a misconfiguration between the URL path set in the
setServiceEntryPoint(URL) call when declaring your RPC service and the
url-pattern URL mapping the the web.xml file.

Now i think i have a misconfiguration between the setting in
setServiceEntryPoint and url-pattern. Below are the entries of the
Gwt.Xml and Web.xml:

Gwt.Xml:
entry-point
class='com.google.gwt.sample.stockwatcher.client.StockWatcher'/

Web.Xml:
servlet-mapping
   servlet-namestockPriceServiceImpl/servlet-name
   url-pattern/stockwatcher/stockPrices/url-pattern
 /servlet-mapping

and the StockPriceService.java:
@RemoteServiceRelativePath(stockPrices)

Can any one tell me what should i do now to do a Url mapping so the
RPC call will be going through.

Re: gzippen all gwt output files?

Yes, only generated files are compressed (this includes static resources 
though, as long as they come from a public path in a compiled GWT module, 
i.e. a theme's CSS).

Also, have you tried wrapping the flush() in a try catch and ignore

 Hi,

 Scenario 1 If I hit url of servlet directly, it always give me desired

 Scenario 2 Using GWT client on IE8,I am able to download file without
 any code changes. However on some other computer as soon as I try to

 Code of servlet is as follows:

 int bytesWritten=0;
 while ((length = data.read(buffer))  0) {
 bytesWritten+=length;
 output.write(buffer, 0, length);}

 output.flush() // At this point I am facing EOF exception.

 where data is inputStream

 Via means of bytesWritten variable I have confirmed that in all the
 three scenarios content has been written in the same way in output
 stream. But not sure why it is not working in some computers.

 Any pointers will be highly appereciated.

You could call setAttribute on the UiField.  This would look like the

EnterButton

2010-12-23 Thread Greg Dougherty

I have a couple of places where I want the user to be able to hit
enter, and have a button clicked.  So I created the class EnterButton,
which has all the default constructors, and the following bit of code:

public void onKeyPress (KeyPressEvent event)
{
int keyCode = event.getNativeEvent ().getKeyCode ();

if (keyCode == KeyCodes.KEY_ENTER)
click ();
}


Is there a reason why some such class isn't part of GWT already?  Is
there something in this code that will turn around and bite me in the
tush?

Where do KeyPress Events go?

2010-12-23 Thread Greg Dougherty

So, now that I have an EnterButton class, I'd like to use it. :-)  I
have a form panel with a FileUpload.  I'd like to let the user select
a file, then hit enter to fire the form submit button (which is an
EnterButton, not a SubmitButton).

Unfortunately, FileUpload does not have an addKeyPressHandler
routine.  So, who gets any key events I generate while in the text
field part of a FileUpload?  What is the call chain for events that
aren't captured by the Widget where the event happens?

Sorry if this is an FAQ, and in the docs.  I took a (quick) look, and
couldn't find anything.  Please point me to the correct docs if it is
in there.

Thanks!

Greg

Re: Flextable with a locked in position header row despite scrolling

Maybe you can even still use one flextable and play around with fixed
positioning of the first row, but its hacky.

But it's a dummy example, if you need to interact or simply manage
displayed content (paging/caching/...) i suggest to use a different
widget, like
CellTable (http://gwt.google.com/samples/Showcase/Showcase.html#!
CwCellTable)
or
PagingScrollTable from the incubator suite (http://
collectionofdemos.appspot.com/demo/

The latter will be supressed in a future release of gwt, so keep it in
mind.

I have seen such tables with some javascript widgets, and I think in
SmartGWT too. However, I want to do this with GWT.

Is it possible? Any hints?

ValueProxy example

2010-12-23 Thread jeremy rose

I've got embedded objects within my entities and it appears as though
ValueProxy is just what I need.  When I tried it out, my values are
always null.  I verified the server-side is retrieving these embedded
values but I'm very new to RequestFactory so I'm sure I did something
wrong wiring things up.  Are there any working examples of ValueProxy
I can follow?

Re: ValueProxy example

Even though they're not really relationships, they probably (I haven't yet 
checked) obey the same rules:
http://code.google.com/webtoolkit/doc/latest/DevGuideRequestFactory.html#relationships

When querying the server, RequestFactory does not automatically populate 
relations in the object graph. To do this, use the with() method on a 
request and specify the related property name as a String:

Request findReq = 
requestFactory.personRequest().find(personId).with(address);

Re: GWT 2.1.1 RequestFactory Strange Exception


from your explanation I get the feeling that Locators are DAOs,
is this correct ?

placing calls like these: EntityManager#find(clazz,id) inside a
Locator,
means Locator is now responsible for accessing datastore to perform
actions.

it also means that our DAOs are somehow directly coupled with
RequestFactoryServlet.

A common design approach is to have a Service Layer and a
DataAccessLayer,
that communicate through interfaces.

when the request comes from the client, it gets routed to the Service
object responsible
for performing a business logic to fulfill clients request.

In doing so, the Service object, may interact with a number of DAOs,
to perform the task.
and if Required, this Service object returns the data that has to be
given to the client.

in GWT 2.1.1 RequestFactory Servlet,

ServiceLocator can be used to locate the Service Object responsible
for fulfilling client request.
However, how the ServiceObject communicates with server-side DAO to
get its data is the ServiceObject concern,
not the RequestFactoryServlet.
In otherwords, our Service Object itself knows how to locate DAOs,
therefore why do we need this Locator for our EntityObjects ?


On Dec 22, 2:19 am, Thomas Broyer t.bro...@gmail.com wrote:
 Well, as always, it depends what you need and what you can do.

 If you can implement a single Locator class that works for all your
 entities, then go with it; and otherwise make one for each entity.
 For instance, if you have a base class for your entities that provides an ID
 and version, then you can easily cast any entity to that class to implement
 getId and getVersion, and you probably can implement getIdType by returning
 a fixed type.
 You can clazz.newInstance() in the create() or use
 PersistenceManager#newInstace with JDO.
 And you can easily find using the Class and ID with JPA using
 EntityManager#find(clazz,id), or with JDO using
 PersistenceManager#getObjectById(clazz,id).

The public path allows for reuse (as for themes). In that sense, its not

Otherwise, yes, you'll put them in the war, but then you're responsible

Re: GWT 2.1.1 RequestFactory Strange Exception

RequestFactory sends diffs on the wire (client-to-server), so how would your 
Service Object (as you call it) would receive a complete domain object if 
the diff isn't applied to an object retrieved from the database/datastore?
Things are a bit more blury than service layer on top of data access 
layer. If you want to name things, RequestFactoryServlet is part of your 
service layer, and delegates a few (a very few) things to DAOs (Locator, or 
static findXxx methods), and all the business logic to other pieces 
(services, as referenced in @Service/@ServiceName, or instance methods on 
your domain objects)

(as for the SL vs. DAL, I never bought that; the few times I used that 
strict approach, one was almost useless; JPA/JDO/whatever *are* the DAL, 
you hardly need an additional layer, and each layer removes some ways of 
optimizing things, notably database/datastore requests; but that's another 
debate)

Re: gzippen all gwt output files?

2010-12-23 Thread Ed Bras

Thanks,
I used to the public folder in the past but didn't like it in reusable
components as you always got the public resources in your project when using
the reusable component, even if you didn't use or want them :(...
Where do you put your static resources ?

Another thing:
I am not sure if MultiViews it the way to use it on Apache as MultiViews is
used for language negotiation (as I understand it) and means that the
requested file should not be present, but it should be present with an
extension.

For example:
Request: bla.nocache.js
the file bla.nocache.js is not allowed to be present on the server. If this
file is present, it will not look for any better (gz) version, and directly
return this file.
What should be present for example:
bla.nocache.js.en
bla.nocache.js.gz.en

Then it will return the file that best meets the browser properties, such
that it will return bla.nocache.js.gz.en.

I got this working with the following config for a directory section in
Apache:
 Options +MultiViews
 AddEncoding x-gzip .gz .tgz
 AddLanguage en .en

But that means that I have to rename all files to have a language extension
:(.. Which is not really the path I want to go in to.
Do I overlook something, or is this really the way to go?

Is selectionModel.setSelected asynchronous?

2010-12-23 Thread Jaroslav Z?ruba

Hello

I'm trying to clear selection on a list that has selectionChangeHandler 
attached to it. This fires a new event that triggers the handler again. I'd 
like to ignore the event that has been triggered as result of me clearing 
the selection.
The problem is that there seems to be stuff happening asynchronously.

new SelectionChangeEvent.Handler()
{
boolean muted = false;

@SuppressWarnings(unchecked)
@Override
public void onSelectionChange(SelectionChangeEvent event)
{
if(muted)
return;

NoSelectionModelUser selectionModel = (NoSelectionModelUser) 
event.getSource();
User user = selectionModel.getLastSelectedObject();
// ...

muted = true;
// I'd expect the following line to launch onSelectionChange again, with 
muted=true
selectionModel.setSelected(user, false);
// instead following one gets evaluated
muted = false;
// and the handler gets triggered after that, obviously with muted=false 
again :(
}
}

I could check whether the user is null and return out of the handler but I 
don't like that kind of workaround because null selection != invalid 
selection; and (more importantly) this ?async? evaluation does not seem 
right...
What am I missing please?

Re: GWT 2.1.1 RequestFactory Strange Exception

Thank you so much for your feedback on this.
I am going to experiment more, using your guidelines.

as for the need for additional layer,
a valid use case could be this:

lets say you are going to deploy your app on GAE.
for the persistence, there are several options:

- JDO/JPA
- DataStore LowLevel APIs
- Objectify, Twig Persist

many of these technologies are new and subject to (rapid) change,
it is a good idea to use interfaces to declare our
DataAccess contract without exposing infrastructure related detail
that is specific
to each of those technologies.


if one has 20 domain objects(entities),
and for each entity,
certain requests/methods : findX, findXInRange, findByX,

it can get out of hand quickly.


it would be very difficult to swap one persistence technology for
another,
sometime down the road.

the idea is,
- loose coupling
- easily swapping infrastructure specific code, without affecting
other part of system
(easy refactoring, testing,)
- clearly defined contracts in the form of interfaces,
when you look at an interface you can see what is expected of this
DAO,
rather than going through hundreds of lines of codes, some of which
scattered with try/catch/finally blocks
(i am exaggerating a bit, IDEs can provide a quick overview)

having said that,
if one is working on a project that
uses a legacy database, a database that's been in that environment for
years,
where DBAs have developed custom scripts, and its been used in day to
day operation of that business/organization for many years,
and there are policies within that business/organization to continue
using that database in the future,
I agree, using abstractions might be an overkill.


As with most things, I believe it all depends on the requirements/
constraints.

Re: Is selectionModel.setSelected asynchronous?

2010-12-23 Thread Y2i

AbstractSelectionModel.setSelected() schedules selection change event
to be fired at the end of the current event loop, so a new event will
be fired after onSelectionChange() is executed.

Re: GWT 2.1.1 RequestFactory Strange Exception

SL vs DAL,

one example of how they are different is that:

let's say
we have a DAO for accessing a Customer entity
a DAO for accessing Account entity
a DAO for accessing History/Trend entity
// maybe not a good example, but just three separate entities

a Service(object) living in a ServiceLayer,
needs to access these three entities,
analyze them and based on a current condition, apply a policy,
and then notify the interested parties.

the Logic for sending Notification is in another Object.
the Logic for Accessing/Finding those entities are in another object.

our Service(object) responsibility is to perform some operation,
with the help of those other objects. (through collaboration).

in this case, our Service is not just a basic CRUD.

to complicate things further, (in a real world scenario),
not all of the data might come from same DataStore,
one using a local DataStore, one a WebService to retrieve realtime
data,

so when going beyond basic CRUD,
the need for a Separate(isolated) ServiceLayer and DataAccessLayer,
becomes more obvious.

Re: gzippen all gwt output files?

Did some more reading and trial and error and have it now working as
followed:

1) In Apache config file:
a):
Directory YOUR GWT DIR 
 Options +MultiViews
 AddEncoding x-gzip .gz .tgz
/Directory

b):
FilesMatch \..js.gz$
  ForceType text/javascript
/FilesMatch

2) Remove all original not-gzipped files such that content negotiation
occurs.

If you remove b) (which I would like) it doesn't work as the Content-
Type that the browser receives of a js.gz will be application/x-gzip
which is wrong as it must be text/javascript, otherwise it doesnt
work. Config snippet b) will force this.
I would suppose that b) isn't necessary and that Apache would discover
and set this them self... but it didn't...

So the question now: is this the way to do it??
My complain: I have to add b) snippets for every content type that is
gzipped: css, js, xml, html, etc.. That seem awkward...

Example of request and response headers:
-

Re: gzippen all gwt output files?

OK :(

Couldn't let it rest...
Found out that the above b) snippet isn't necessary, but was because I
had somewhere in my apache config the following line that spoiled it:
 AddType application/x-gzip .gz .tgz
So every file returned with .gz as extension got automatically this
content type back which was incorrect

Bottom line:
1) Remove all not gzipped files otherwise apache will not perform any
content negotiation and simple returns the unzipped file.
2) Add the following lines to your apache config (in a Directory/Files/
Location directive if you whish):
Options +MultiViews
AddEncoding x-gzip .gz

And that's it...
Because all the modern browsers support gzip, it's safe to remove the
original unzipped files.

Now I still have to find out how to gzip my remaining static
resources...
Thomas: how do you that ? and where you put your static resources?

Re: 2.1 MVP and handlers

2010-12-23 Thread sunny...@gmail.com

Thanks Thomas and Y2i - shortly after I posted I read in the API that
the EventBus passed in onStart is a ResettableEventBus (that wraps the
EventBus given in the ActivityManager?)

My application is a tabbed application (its quite good for our
workflow) with a secure login. There is a full screen login widget,
and that is replaced by a SmartGWT TabSet once the login succeeds.
Tabs are generated once the user logs in based on their permissions.
Each tab also has its own Activity+View. The TabSet is only simulated,
there is only one content panel which is used by the ActivityManager
to change the View. The TabSet has listeners on PlaceChangeEvent and
change the selected tab accordingly.

The way I've approached this as a first pass test is that there is a
PlaceController+ActivityMapper+ActivityManager+EventBus for going
between the login page and the TabSet. There is also a second set of
PlaceController+ActivityMapper+ActivityManager+EventBus thats used by
the TabSet itself to go between the different tabs.

Amazingly this works really well - logging in, switching tabs, and
logging out all works wonderfully. However, history falls apart. I
would have hoped the back/forward buttons take me through the tabs (I
can see the tokens appearing correctly in the address bar). atm I also
have two PlaceHistoryHandlers - I'm assuming this is where my problem
is.

Unfortunately I think I simply don't have a good enough understanding
of the interaction of these new classes to make an informed choice on
what I should be doing.

1) Judging from the PlaceHistoryHandler source each instance of
PlaceHistoryHandler should receive the change event - do I need a more
sophisticated Historian to handle whether the change event (eg, just a
tab changing, or logging out) should be handled by that
PlaceHistoryHandler?

2) Having two PlaceControllers seems illogical to me, but this was a
side effect of having two PlaceHistoryHandlers. I think I'm quite
confused here as to how it should come together?

  Hi everyone,

  Before 2.1 I created an application that use the old MVP
  architecture of having models, views and presenters. This worked quite
  well. I'm migrating this application to use the 2.1 MVP framework now.
  I've made some progress but am still getting my head around it.

  This has hit me so far: in my old code, the presenter was responsible
  for setting the listeners/handlers on the view/eventbus respectively.
  Where appropriate handlers would be removed when the view changed so
  that events are not handled more than once. (eg, I destroy my login
  window once login succeeds, and I also remove the eventbus
  LoginSucceededEvent handler, so after logging out there aren't two of
  them listening on the eventbus)

  Here is the start method of the apps' login activity:
  @Override
  public void start(AcceptsOneWidget panel, EventBus eventBus) {
  LoginView view = clientFactory.getLoginView();  // just one instance
  bindView(view);   // eg, view.getButton().addClickHandler(...
  bindEvents(view, eventBus);   // eg, eventBus.addHandler(
  panel.setWidget(view.asWidget());
  }

  The LoginView is reused from the ClientFactory as the documentation
  suggests. This raises two questions:

  1) I would like to keep the GUI bindings outside the UI code (just as
  I did in the old code where it was in the presenter). But since the
  documentation suggests using a single instance of a the views, here I
  would be adding more and more listeners each time the activity is
  initialised (as they are in the ActivityMapper). The HelloMVP example
  has the binding code in the view and allows the view to communicate
  with the activity. Can this be avoided? It would help in keeping the
  UI code strictly to UI and presentation. Short of implementing a
  method on all views that clear its listeners I cannot think of a
  better way (I would still think this to be cumbersome - its not
  something you'd normally do)

 First, you have to understand the why of this suggestion: everything
 DOM-related is slow. This means that creating a view is slow (compared to
 creating any other POJO, such as your presenters/activities).
 Having initially worked with the HasXxxHandlers approach (MVP tutorial -
 part 1) and later switched to the delegates approach (quite some time
 before the MVP tutorial - part 2 and places  activities tutorials were
 written), I assure you that writing unit tests is wy easier with the
 latter ! (I also find the presenter code more readable, and it allows using
 @UiHandler methods in your view if you use UiBinder). If you want to make
 the switch, I assure you you won't regret it.

 That being said, you're not forced to do the switch. If you want to keep
 your addXxxHandler calls in your presenter, then you'll have to remove them
 when the activity is over. This means

File user/src/com/google/gwt/i18n/client/DateTimeFormatInfo.java
(right):

user/src/com/google/gwt/i18n/client/DateTimeFormatInfo.java:337: int
weekendStart();
This will generate checkstyle errors for the methods being out of order.
 Instead, change the javadoc.

than {...@link #weekendEnd()} - for example, {...@link #weekendEnd()} of 6
Please fix the formatting of the javadoc while you are here, and change
the first weekendEnd on this line to weekendStart.
Also, the 6/0 should be swapped.

I think the Javadoc for weekendEnd should be:



Returns the day which ends the weekend, as an index into the return

value of

{...@link #weekdaysFull()}.
pNote that this value may be numerically less than

{...@link#weekendend()} - for

example, {...@link #weekendStart()} of 6 and {...@link #weekendEnd()} of 0

means

Saturday and Sunday are the weekend.


Looks like that note belongs to weekendStart, doesn't it?

You could have it on either or both, but it seems more natural to say
the endpoint could be before the start point on the end point.

Makes sense, just need to update that first link which threw me off
then.
