Re: GWT Performace Tips

2011-02-12 Thread Flemming Boller

1) Instead of the Vertifal/HorizontalPanels use UIBinder instead. We almost
never use those panels
but use uibinder and normal html instead.

2) Could you tell a little bit about how you found your performance
problems?

 Thanks everyone for the tips.  I have found the source of some of my
 current problems.  One issue is that we were passing around a very
 large and complex object in some of our RPC calls.  I have heard that
 serialization can be slow in IE, and I believe that is the case for
 me.  I redesigned the calls to no longer pass the object and it sped
 things up dramatically.

 There are still a few slow spots.  We construct several complex panels
 with many tables and rows of data in them.  We are mostly using
 VerticalPanels and HorizontalPanels to create these panels.  It seems
 like the initial creation of these panesl are slow in IE.  Any
 thoughts on how to speed that up?

Re: 2.1 Documentation

2010-10-07 Thread Flemming Boller

Hi Aldo

Why is it so important for you to start a project with the GA - release ?

Normally enterprise projects are have quite a big development time, so the
GA release could properly be avaiable before you enter the first testphase.

We are currently running with 2.1M3 in production, and have found 0 errrors
that can be blaimed to the GWT. We are also a rather big enterprise
project.

I think the quality is very good and the bikeshed examples are good
learning places.

What can you take from me? We have good experience with 2.1M3...I think
google code quality is very good even though they call i M3.

Is it good enough for you? That is of course for you to decide.

Hope you can use my input.

Other practices we use and I would recommend:
- DVCS (we use mercurial hosted on bitbucket)
- Use a highly decoupled architecture, consider an MVP framework. (we
use gwt-platform)
- Heavily unit test (we use JUnit4, mockito)
- Use DI to simplify the two above (we use GIN and Guice)
- Use integration testing (we're still experimenting tools in this

- Asynchronous code reviews (rietveld works really well for us)
- Use UiBinder so that you can easily port HTML mockups to GWT.

Hello all

I'm looking for best practices in developing GWT apps. Let's assume we
are 3-5 programmers working on a fairly big GWT app.
I could not find any straightforward information on this. Maybe
because it's absolutely clear for most developers or maybe there are
just too many possible solutions.

I know that this is not just a GWT specific question.

Anyways, back to our scenario. Let's assume its an GWT app with a
database behind, and using JAVA in the backend. Everything is working
on Linux basis.

My situation: I'm developing and debugging locally, then deploy
the .war file manually on my tomcat server. This works fine when
working alone. Now, a couple of friends want to join in. The whole
thing gets complex. What setup (e.g. server, software) would you use
to handle such a scenario?

Here are a couple thoughts I ran into:

1. Should each developer develop and debug locally (sharing files via
subversion) ? There is a big down-side on this. Each developer needs
to do the server configuration in order to keep the app running
locally. Is there an alternative?

2. How can one add server-side debug ability to the test server? On
the test server runs the app in hosted mode. How can errors, warnings
be stored and outputted to the developer? Is there a software or do
you work with error logs?

3. How can one export the files from a test server to a production
server? Is there any software which supports such function?

I'm programming for quite a while now, but I don't have any
experiences in programming together with other developers. So,
basically I would love to know anything how you guys develop GWT apps
in teams.

Please let me know if I shall be more precise.

Thanks for your tips!

AFAICT the incubator is not a sound choice to base anything serious

Re: Maven users survey

2010-01-21 Thread Flemming Boller

We, at my work, use a different approach, than others I see mentioned here.

Development:
We are developers using eclipse and Intellij. Important for us is IDE
indenpendent usage, so I have created a Launcher.java file
which actually starts HostedMode.java with appropriate arguments. That way
the setup in eclipse and Intellij is the same, as developing e.g a swing
client.

Build process.
For the build process it self we use maven2, but do NOT use any gwt plugins.
Our build consists of many jar files and war files.
Everythings gets build by maven2 except for the UserInterface modules. Here
we use the maven-antrun-plugin to wrap the build.xml, and still get the
benefit of maven2 dependencies management.

Actually it is working quite great for us. Our appliction sofar has lived
for 1.5 years, and I expect the lifetime to be bigger than 7-10 years. (our
previously strus app, sofar has been used for almost 10 years).

Hi folks,

For the next release of the Google Plugin for Eclipse, we're planning on
making a few tweaks to make life easier for Maven users. That's right: we've
seen the stars on the issue tracker, and have decided it's time to act. I
would say, we feel your pain, but the problem is, we don't. Which is to
say, nobody on the plugin team actually uses Maven (everybody around here
uses Ant). However, I've been researching Maven to determine exactly what
changes we should make to allow it to work more seamlessly with the Google
Eclipse Plugin. I've read the relevant issues and groups postings, so I
think I have a rough idea of what needs to happen. However, before we go and
make any changes, I wanted to ask for the community's advice. So, here are
some questions for you.

What is the typical workflow of a GWT developer using Maven?

I've installed Maven and the gwt-maven-plugin 1.2-SNAPSHOT and managed to
create a GWT 2.0 app with the provided archetype. After some tweaking, I'm
able to GWT compile, debug with Eclipse (though not via our Web App launch
configuration), create a WAR, etc. However, I'm more interested in how
you all are doing things. For example:

How do you...

- Create a new project?
- Perform GWT compiles?
- Debug with Eclipse?
- Run your tests?
- Create a WAR for deployment?

What specific pain points do Maven users run into when using the Google
plugin?

I know one major obstacle is that our plugin currently treats the war
directory as both an input (e.g. static resources, WEB-INF/lib,
WEB-INF/web.xml) and output (WEB-INF/classes, GWT artifacts like nocache.js
and hosted.html) . Maven convention, however, says that /src/main/webapp
should be input only, which means that hosted mode (or development mode, in
GWT 2.0) needs to run from a staging directory (e.g. gwt:run creates a /war
folder on demand). This mismatch results in the plugin creating spurious
validation errors and breaks our Web App launch configuration.

Another incompatibility is that Maven projects depend on the GWT Jars in
the Maven repo, whereas our plugin expects to always find a GWT SDK library
on the classpath.

Are my descriptions of these pain points accurate? If so, one possible
solution would be for the plugin to allow the definition of an input war
directory (e.g. src/main/webapp) separate from a launch-time staging
directory, and for us to relax the requirement that all GWT projects must
have a GWT SDK library. So tell me: would these changes adequately reduce
the friction between Maven and the Google plugin?

Also, are there other problems Maven users are running into when using the
plugin?

Thanks in advance for all feedback,

Keith, on behalf of the Google Plugin for Eclipse team

On Sun, Jan 3, 2010 at 8:36 PM, Chris Ramsdale cramsd...@google.com wrote:

Yaakov,

Having multiple presenters driving a single view would be a bit strange.
Typically want to the presenter to define the display interface that the
view will implement. Having multiple presenters drive a single view means
that either a) the display interface is defined in some parent presenter
class, or b) one of the presenters is responsible for defining the display
interface. Either way, it decouples the presenter-display relationship that
is inherent to the MVP architecture.

For applications with large UI frontends, you could consider breaking the
UI up into smaller presenter/view pairs that are managed by some controller
class. Take for example Gmail; the folder list would be one presenter with
an associated view, the inbox list another, the Google Talk interface
another, and so on. All of these would then be managed by some
MainViewController class.

Keeping widget-based code out of the presenter for ease of testing is
golden. Beyond that it's really a question how much code you want to
maintain within a single presenter and view.

Chris, or anyone else with experience on MVP in GWT...

Practically, do you always have 1 view as the user sees it, i.e., the
whole GUI, or if your GUI has many components (as most GUIs do), do
you have multiple views, and most importantly, multiple presenters,
presenting 1 coherent view to the user? In your example, this would be
similar to splitting the GUI into a view that has the buttons and the
GUI that has the list.

How would that be handled in MVP?

Thanks,
Yaakov.

Re: Use smartgwt or not

2009-12-17 Thread Flemming Boller

I think these javascript wrappers will have a hard time, with all new
features coming from GWT.

Code split, UiBinder etc.. I am excited to see how they will integrate it.

I used ext-gwt, which had a pretty big startup-download-size. Unfotunally it
was javascript coming from EXT, and not GWT, so codesplit was not going to
help here.

Anybody have any thought about this?

We're just now evaluating this ourselves, but we do like the look of their
large variety of widgets, but it is big and takes time to really evaluate it
all and there are myriad options from LGPL through proprietary EE. No
doubt, much depends on your app's needs. Ours is more business-focused, so
I think it's a good match, hence our eval will begin in earnest in January.
GWT's widgets just don't have much to show for grids tied to server data for
ACID/CRUD operations, and the DataSource concept seems powerful should it
pan out, which we expect it will from what we've read. But any real-world
experiences are most welcome.

I am a bit concerned about some items like turn off Firebug because it
runs inordinately slow -- why their JS is overly impacted is not clear. I
have seen some odd painting issues in the showcase examples on FF3.5/Win7.
Do check out their forums though to see what others are saying and reporting
as they may match what you intend to do.

I'm also not sure what it means to integrate SmartGWT with CKEditor yet,
but we want to use the more powerful layout capabilities of CKEditor.

Re: A native GWT chart library?

2009-04-21 Thread Flemming Boller

Hi

I currently use the GWTCanvas, for creating pies. It works very well.

The code I can just copy paste from swing/awt code examples because the
GWTCanvas
api is very much like the normal jdk canvas. And you can your self attach
mouse listeners etc on the pie so it becomes interactive, with the rest of
the page.

So for pies it is well suited.

However I have not cracked the nutt with respect to drawing  text in the
canvas, last time I checked the versiondid not support drawString(...)
method, so that was a no go.

/Flemming


ps: if you want I can attach the code.

  I unfortunately can't use Google Visualization bc it's for an intranet

 Huh! no flash?! Which browser(s) are you targetting?
 If you only plan on supporting relatively modern browsers and/or IE,
 then you could use SVG or canvas (for the formers) and VML for the
 latter (I guess silverlight or java applets aren't an option either?).
 There are a few GWT projects for charting based on canvas but they
 don't seem maintained... (for example http://code.google.com/p/glotr/
 )
 You can eventually use the GWTCanvas widget from the GWT Incubator and
 do the plotting/charting by yourself:
 http://code.google.com/p/google-web-toolkit-incubator/wiki/GWTCanvas

 Unfortunately, Chronoscope doesn't meet your criterias as it doesn't
 do pies (it's oriented towards time-based data...), otherwise, it's a
 very well-thought-out project from one of the best GWT user/
 contributor out there!

Hi

Do any of you guys know what will happen with GWT-EXT when 1.6 comes out?

I could imagine a lot of fixes would be needed, because of the changed
event system.

Anyway to answer to this thread, I have used gwt-ext, in a project.
benefit: we could quickly produce a very nice looking and feeling
application.
drawback: slow hosted mode!, hard to really customize and create your own
widgets. We also had bad experience with mixing native gwt widgets and
gwt-ext widgets. (which was really diapointing, cause with native gwt we can
create custom widgets

Thanks for your answer.

 The GWT 1.6 event API is not an API breaking change, and besides the

 Ext and things ran fine.

  Do any of you guys know what will happen with GWT-EXT when 1.6 comes out?
 
  I could imagine a lot of fixes would be needed, because of the changed
  event system.
 
  Anyway to answer to this thread, I have used gwt-ext, in a project.
  benefit: we could quickly produce a very nice looking and feeling
  application.
  drawback: slow hosted mode!, hard to really customize and create your
 own
  widgets. We also had bad experience with mixing native gwt widgets and

 can

Hello all. We (small start-up company) are currently considering to

Now that you mention SmallTalk... I of course agree!

 I don't know how relevant this is, but MVC was first so-named by a
 bunch of people designing GUIs in SmallTalk.  I don't remember the
 timeframe, but it was definitely before web frameworks became at all
 popular.  There's some interesting discussion of the pattern here:

Re: Need for a great GWT GUI library

2008-12-23 Thread Flemming Boller

Hi

I have being following this thread with great attention.
Current status for my project is that we have used gwt-ext alot last couple
of months and we think it looks really good (extjs is a very nice look and
feel)

However due to thing also mentined in this thread, I am also looking for
different ways to go.

I would like to have a javascript wrapper free solution

In my searching i also found gwt-mosaic, which I think is a nice
alternative, but It would require
our users to get used to yet another look and feel.

So I have the last couple of days, played around with the standard GWT
widgets, tweaked them a little as we normally do :-), and applied the CSS
and images of EXT-GWT.

I actually think that it looks very well. At least my users and developers
was not able to see the difference, between ext-gwt solution and my pure
gwt solution.

I have so far converted buttons, panel with collapse and toolbar input
fields, and tabs.
My experience with css is VERY limited, but with my progress sofar, I
believe it is possible to acheive the whole application, because sofar we
use a very small number of different components.

Do any of you guys see any value in this?

For me it means that we are now more free to extend components in a more OO
like, way
and we now have possibility to take in other 3part libraries based on pure
gwt.
and also, the development turnaround in hosted mode is by far quicker.

 +1. Fortunately, you can use POJOs, as said above.
 AFAIK, generics issues will be fixed in 2.0 release.

 
  Many of the examples don't even use generics.
 
  2) The GXT components are not easily extendable.  In Swing terms,
  imagine if you extend JLabel and override paintComponent.  Instead of
  rendering a label you render a red square.  Nothing breaks and you
  have your nice shiny square.  If you take a GXT button and override
  onRender with a completely new impl, chances are you will break
  several things.  Other methods in the class depend on certain elements
  to exist in the DOM or certain styles to exist in the Elements.  If
  you plan on using GXT's components as is or customizing the CSS
  slightly you should be fine.

I've been using GXT (Ext-GWT) for quite some time now.  While it
certainly looks nice and provides a good amount of functionality
lacking in GWT, there are several drawbacks.
 
1) It is very buggy.  Bugs get fixed fairly fast, which is good, but
 I
find myself submitting an abnormally large amount of bugs.  While the
developer (singular) is very responsive, passionate about his work,
and friendly, the code isn't exactly up to the standards that was
hoping for.
 
2) It is not just a set of widgets, it's a complete framework on top
of GWT.  Your team will have to invest time to learn it.
Intermingling GWT widgets and GXT widgets is possible, but confusing
IMHO.  Which leads me to my next issue.
 
3) Documentation is still very lacking, although they're working on
it...
 
4) There's some really iffy design decisions.
a) The use of generics is not only inconsistent, but in many cases
it's not even possible to use generics due to API bugs.  The example
 I
was going to post was actually just fixed in the release today.
b) While the widgets look nice and performance is OK, you are forced
to back the GXT components (like Grid, Tree, List) with GXT specific
data model objects.  If you have a simple Employee POJO, and you want
to add it to a GXT Grid, you have to either wrap it in a Model or
ModelData class, or you have to implement a marker interface and do a
bit of trickery to get it in the Grid.  The only reason for all of
this is to support binding (since GWT doesn't support reflection).  I
would much rather have preferred a Swing like TableModel and an
optional binding layer on top of it.
c) The widgets look nice out of the box and customizing them slightly
with CSS is pretty easy.  However, if the changes require you to
 alter
the HTML of a GXT component, you're in for a world of pain.  The HTML
markup is tied heavily into the functionality of the widgets and is
referenced throughout the class either by tag name, tag id, or by css
class.  IMHO, the UI should be completely separate from the
functionality of the

Yes I am.  I think is it rather nice little MVC implementation, which has
made it more easy for us to make
components talk to each other in a loosely coupled way.

Minus is however, that it easy also to create a spider web of notifications
that is hard to overview.

But common sense and keep it simple should be used here :-)
