GWT UI component programming with Fluent Interface Pattern and attribute oriented programming.

[jimmy6]

Improve the GWT UI component programming with Fluent Interface Pattern
and attribute oriented programming.
Have a look at this blog to mention the issue and the way to solve it.
http://j6framework.blogspot.com/2008/12/gwt-ui-component-with-fluent-interface.html
Have you guy consider annotation to be work in runtime inorder to
solve it? It can be use together with Hibernate annotation validation
(nullable,length) in databinding. Thus, we do not have to code the
lenght,require... again and again...

Right.  My reason for offering it as an example was you can use the client
by itself, without touching the server at all.  Its meant to permit
implementation of the GWT server side in any system that has the ability to
create JSON text, which is anything that can create text.  :)

You just need to have the Java objects the client side is using have
property names which match up with the property names appearing in the JSON
data - but that's probably exactly what you would want to do if you were
interfacing with an existing JSON service, or were developing one from
scratch.

Let me learn about GWT generators before I can comprehend it :-)
>

You shouldn't need to know alot to use it.  Run "make", copy gwtjsonrpc.jar
into your CLASSPATH and inherit the module.  GWT's compiler automatically
calls RemoteJsonProxyGenerator when you declare an interface extending
RemoteJsonService and create an instance of it with GWT.create().

Wow.
Looks impressive!
Thank you!

> I think it mostly does what you are looking for,

It does a lot more (I'd prefer to leave the server side to Jersey and
I'll make a RESTful service instead of RPC), but from what I
understand, your RemoteJsonServiceProxyGenerator seems to do what I
want.

Let me learn about GWT generators before I can comprehend it :-)

That's probably OK for me, my entities are quite simple, mapped
without extra annotations. I might have to add support for the
@XmlTransient later at most.

Sounds like a good general purpose project for bored GWT pros though:
"JSO generator from JAXB for JSON"

(Or am I trying to do something unreasonable here? I mean how come I'm
the first to complain about this?)


Gabor Szokoli

Ps: Generators... This new learning amazes me. Next thing we know GWT
will be employed to prevent earthquakes.

Rate my gwt project.

[thebuz...@gmail.com]

Here is a quotation program that we are going to allow our customers
to use to get quotations.

http://www.ottocap.com:8080/workflow/onlinedemo.jsp

Technologies used:

UI: GWT
Backend: jsp,java, iText library, Batik library, Adaphie commons
Library

All coded by me which kind of sucks. Working at my dad's company and
being the only programmer while they won't hire other programmers
because it will be expensive. So a 23 year old right out of college
working by myself for a program that the company is using.

What you see here is just what the customers will see there is a whole
other gui and more pdfs for the employees to use.

This whole program calculates everything they need for a order. And
the formula for this is not that simple because everything such as
quantity of similer items, quantity  of logos, stitch count, etc all
changes the price.

So have fun looking at it and if you see some weird bug in the program
please tell me @ d...@ottocap.com

also you might want to download and upload some DST format files into
the program for some cool artwork options. Also choose overseas cap
for line art type drawing.

Also just wondering if they paid a company to make a product like
this. how much would they get charged.

Re: My GWT Ant task wont find my remote service

[Eric Ayers]

Wait, I think I know what's going on.

When you run in Eclipse, it is compiling all the java source to .class
files and putting them .  I'll bet that is not the \bin
directory you've specified in your classpath in your ant script or
your .bat file.

To fix the problem, you need to compile the java files for your
servlet in the server package into the \bin directory with a   new ant
target, then have your gwt-shell target depend on it.

GWT integrated with JSF

[will.dutt]

i've been look around for anything that was happening with these 2
great components. sadly the g4jsf is a dead end :(.

i've got a JSF website that is now hitting the boundaries of what is
possible in a static html refresh browser and needs GWT badly.

does anyone have any good examples of integrating GWT components to
pull information from the page its placed on and rpc the rest of the
content it needs?

i can place a GWT compenent on the page with div's which is good, but
i'm having trouble getting information from the page (eg ID that link
to a database). what is the command to do that?

Re: Dictionary on demand

[ECH]

Thank you for this sample, very interesting.

Just for information, where do you instanciate DictionaryOnDemand?

In my case, I create it in the onModuleLoad method, because I need it
in view initialization, but the problem is that : because of deffered
command (but needed...), dictionnary is binded after view init

Any idea?

Thank again,

Oh, and in your web.xml's that you ship to your production environment
you would have a different listener setup.

Re: Best way to add App configuration properties

[Joe Cole]

Here is our way:

In:
tomcat/webapps/ROOT/WEB-INF/web.xml


  jdbc/dbsource
  javax.sql.DataSource
  Container


  com.yourcompany.LocalConfiguration


The only gotcha with this is that when you upgrade gwt it changes the
web.xml - we just revert it from version control and all works well.

That listener sets up the entire servlet side, including properties &
guice bindings:

public class LocalConfiguration extends AbstractConfiguration {
protected IPropertyManager createPropertyManager(
final ServletContext context) {
return new LocalPropertyManager();
}
public IBindings getBindings() {
return new LocalBindings();
}
}

This allows us to ship different setups to the system depending on
where it's being used (one for hosted mode, production, test, staging
etc).
The datasource is container managed which is why it's defined in the
file.

The other file you will need for hosted mode is:
tomcat/conf/gwt/localhost/ROOT.xml











factory

 
org.apache.commons.dbcp.BasicDataSourceFactory




username
YOURDBUSERNAME


password
SECRET


driverClassName
org.postgresql.Driver


url
jdbc:postgresql://URL/DB





Let me know if this is useful - it took us a while to get this right,
and we have used it in multiple deployed apps and it works well.

Best way to add App configuration properties

[mdwarne]

Hi,

I am trying to figure out the best way to add an application config
file.  This file will contain things like database connection
information, and other app parameters.

I will be using Tomcat as the servlet container.  I would like this
config file to be readable by the Servlet in the Hosted mode browser
(development mode) but also when deployed to a production Tomcat
environment.

Any thoughts?

Thanks,
Mike.

Re: Will be GWT development stopped ?

[Sumit Chandel]

Hi jan.kubeja,

There are no plans to cease development on GWT. As Pierre pointed out, we
have an active roadmap and much activity in the Groups and blog, the SVN
trunk and the issue tracker.

May I ask where you heard that GWT development would be stopped?

Regards,
-Sumit Chandel

Re: Browser caching GWT javascript app

[Shawn Pearce]

Near as I can tell, the browser and server are working correctly.

The browser sent a request along with the data it has in cache; the server
responded with a 304 Not Modified, letting the browser know that its cached
copy is still current.  Thus the server can save time and bandwidth by not
resending content the browser already has.

If you deploy a new version of the application, the client still should have
validated the content, but the server would have sent back a 200 response
with the new version, holding a different ETag and a different Last-Modified
date.

Re: GWT JSON library with JAXB class reuse?

[Shawn Pearce]

You might want to look at my still-under-development gwtjsonrpc:


http://android.git.kernel.org/?p=tools/gwtjsonrpc.git;a=blob;f=README;hb=HEAD

I think it mostly does what you are looking for, but it doesn't pay any
attention to JAXB annotations.  Its mostly complete for my application's
needs, but I haven't put it into production yet.

Re: Linked source folder in Eclipse project and GWT

[Eric Ayers]

All the source code you'd like the GWT compiler to see must be
referenced in a GWT module.

So you might need to explicitly add in a '' tag in one of
your .gwt.xml files

Re: Geocode Directions?

[Eric Ayers]

You can use the Directions class and just not add the results to the
app.

http://gwt-google-apis.googlecode.com/svn/javadoc/maps/1.0/index.html

The DirectionsResult object returned should give you the information
you are asking for.

Browser caching GWT javascript app

[omsrobert]

We're using Tomcat 6.0.18 and GWT 1.5.3.  The browser (Firefox 3 at
least) is caching our GWT application. Refreshing fixes it but that's
not an option for production.  I would think this is a common issue.
How do we fix it?  Write a response header filter for Tomcat or is
there a better way?

Here's the HTTP headers:

http://ourserver/mywebapp/home/com.mycompany.mine.OurGWTApp.nocache.js

GET /mywebapp/home/com.mycompany.mine.OurGWTApp.nocache.js HTTP/1.1

use of GWT

[MaxBioversity]

Hi,

Just to inform you that we worked with GWT to publish a database
online. GWT was helpful, because of the possibility to reuse previous
development on JAVA/hibernate.
The web site is visible under following link: 
http://www.banana-diversity.org/mgis.
Later new features will be added.

We are looking for feedback on how we use GWT. Did we use it
appropriately ? How should we improve the user experience? Please
advice.

Best Regards,
Max

GWT JSON library with JAXB class reuse?

[Gabor Szokoli]

Hi there!

I'm new to GWT and think it's great. Please keep in mind the below is
intended in a far more humble and grateful tone than I can represent
in English:

We're doing a pilot with GWT, hoping to create a "static" (client
only) application that uses an existing REST-like JSON service
implemented with Jersey.
The initial implementation uses RequestBuilder, eval, and a dumb overlay type.
JSONParser would be an alternative, producing JSONArray.

What I'd prefer instead is reuse of my existing (JAXB annotated) Java
class from the server side in GWT client code.

This is of course not an issue in the pilot project itself, but will
get uncomfortable in larger projects.
It also negates what we expected to be one of the main advantages of
implementing the web service and the client application in the same
language: code reuse.

Does any of the existing GWT JSON libraries support this?
This is the closest I have found, but it looks abandoned:
http://code.google.com/p/gwt-jsonizer/

Or is there a more server-side friendly alternative to
JavaScriptObject for overlay types? (JAXB and JPA frown upon the
protected constructor)
I guess not, so can we have one? :-)
I assume a lot of thought went into the current overlay type design,
but server side code reuse does not seem to have been a design goal,
and might require an alternative binding method.


Any advice appreciated:

Gabor Szokoli

Re: Unsaved Changes Pop Up

Hi Carlos,

That's not behavior that's in GWT out of the box. This sounds like a
customization that your team made.

Re: Standard/Simple GWT CSS?

[David Hoffer]

You seem to get my point.  Its a classic catch-22 situation.  I can't
get access to the graphics designer until I can prove what GWT can do
for us.  Others, using a different technology i.e. Flex?, are going to
be able to create a decent looking UI themselves without the need of a
graphics specialist.

GWT seems quite poor at doing rapid prototyping unless you happen to
have both Java and graphics designers in your development team.

I have spent more time getting the prototype to look decent than
developing the functionality :(

 We also didn't (and still don't) want to write HTML or CSS for our

 what you're looking for. These libraries provide a set of widgets and
 look and feels and let you define your own. They also allow you to
 devlop in a Swing-style by using standard layouts (BorderLayout,
 CenterLayout,...).

 We choose Ext GWT because it is a full GWT library (others are
 wrapping a JS library), it provides a simple MVC layer and has more
 documentation.

We (myself an intern) used GWT-ext for a new project some time ago. We
had to abandon it for vanilla GWT because of speed issues,
incompatibility with regular GWT, difficulty to debug and develop with
because hosted mode crawled, and overall poor quality and bugs present
in the library. I'm aware there is a learning curve with any new
library, but we found that you either go all the way with GWT-ext or
not at all.

Well we create new widgets using the vanilla and incubator ones.

IMHO, what ultimately counts is user experience. If the application is
slow and buggy but has lots of animations and effects, the user is not
going to have a good experience. However, if the application is super
speedy and has a few nice animations where it makes sense, the user
will have a much better experience.

I think what also counts is the maintainability and scalability of
one's application. If the application is going to become quickly
unmaintainable because of quirks in the third party GWT libraries or
because core JDK and JDBC were used to (poorly) duplicate
functionality found in Spring/EJB and ORMs, the project will probably
fail or require a complete rewrite. I've been in that situation.

This is the same question to ask whether a project should be done the
right way by unit testing, integration test, acceptance testing, using
a SCM, using a bug tracker, using a Continuous Integration solution,
etc or whether it should be hacked it together and "we'll figure it
out later" (also been there :P).

The grid that we provided in the past (custom made) and will provide
in the future (gwt-incubator PagingScrollTable) will only be used to
show search results. We don't need a complex grid widget for our
specific applications. We have built in house components, but a lot of
projects have widgets that are very specific to those project. We do
have an OSS project that's undergoing changes atm. I'll be making an
announcement when it's ready for use. I'm throwing out a lot of the
components we built because the GWT team is providing them either in
the trunk or in the incubator. As for the end user, it's the same
reasons I mentioned above. Our widgets are built with vanilla GWT so
they're quick and also well tested.

Not sure about that :P

You can't really see the applications we work on because they're
internal only (there is a file transfer system that is external, but
it's rather small). A lot of the projects are still in development
since we're working on about 6 projects (going between them after one
Sprint). Our medium to large sized projects are usually 300-600
person-hours of work. There is only 1.5 full time equivalent people
working on them at the moment (myself and a part time person). I can't
be any more specific then that.

I just want to leave off with one point. I'm not against third party
libraries in general, in fact, I'd love to have a library with shiny
widgets. I've just had first hand experience with one of these
libraries and have spoken to many people who use other ones (i.e. Ext
GWT). In both cases, these third party libraries were either abandoned
or in the process of being abandoned. If someone comes out with a
third party library that's on par with the vanilla GWT widgets in
terms of stability and speed, I'll jump on them.

Hi David,

I do agree with you that for the initial prototyping and maybe initial
production releases it would be nice to have some polished CSS.
However, I think that in general it's a much better use of resources
to get a graphics designer to come up with the L & F and layout of
your application. You might also find the following GWT blog posting

 Hi Gregor,

 Thanks for the detailed response I will give this a try today.

 As I read this I thought of a couple questions.

 1. Does my CSS file have to have a particular name?  You say it goes
 next to the HTML file.  Do I just name it the same but with css
 extension and it will be found or do I have to reference it somehow in
 my HTML/XML?

 2. You mentioned to look at the showcase examples to get CSS to use.
 I looked at all these yesterday and found that most do not show the
 CSS used (I think most of the widgets did but most containers did
 not).  I then looked at the source code for showcase given in the GWT
 examples and it seems they are using annotations to bring in styling
 information.  What's up with this?  It seems there is more than one
 way to apply CSS in GWT.  This makes it harder to learn how one is to
 do this.

 As an example of what currently looks really bad...DialogBox and
 VerticalSplitPanel.  The former has no border so it doesn't even look
 remotely like a DialogBox and VerticalSplitPanel only has a splitter
 bar...no border.  So unless you really know there is a split panel you
 have no idea what you are looking at.  For these examples the showcase
 shows no CSS so apparently it is using annotations to bring in
 styling.  BTW, for these cases I am using the standard theme.

 Thanks much, I will look at your example.

Re: Linked source folder in Eclipse project and GWT

We did something like this on one of our GWT projects.  Unfortunately,
I'm not in the office right now and don't remember exactly what we
did.  But when I return (next week), I'll look at and post here.  It
seems like we had to do some work on both the gwt.xml and the hosted
mode tomcat web.xml.  It did create a synchronization issue between
making Eclipse happy and keeping hosted mode happy.  And if I
remember, we had do some work in ant to get our deployables to be
correct as well.  So I'll take a look at it and post here..

Horizontal scroll grid

[Ramesh]

Hi,
I placed a grid in ScrollPanel which is placed in HorizontalPanel.
I set the sizes of the panels to 100% so that they can fit to their
parent window.
When the content of the grid exceeds the size of the scroll panel, it
has to display the horizontal scrollbar, but instead of this the
scroll panel is getting extended to fit the size of the grid.

When i set the scrollpanel size in pixels, its behaving correctly, but
i can't set the size of the scroll panel to fixed width, as it has to
fix based on its parent panel which is resizable.

Case:
But its behaving correctly even with percentages when i explicitly set
the scrollpanel to show its vertical scrollbar.

did any one know the work around for this issue?

Re: Does GWT depend on OS?

[olivier FRESSE]

The war can be corrupted in the transfer from windows to the unix server.
For example, an FTP transfer in ascii mode...
as a war is a jar file, you can test it with jar -tvf myfile.war.

Questions that describe a problem with "doesn't work" can
only be answered with "something must be wrong". Can you
be a bit more specific with your description please?

The moment you deployed the whole thing, there is no trace of
GWT anymore. On the server-side you have servlets, on the client-
side HTML and Javascript, so I'm quite sure the problem resides
in your code or the way you create the WAR.

Does GWT depend on OS?

[MAK]

I have a strange experience, that a GWT application (war file) is
running when it is deployed on Windows machine, copied the war file to
tomcat's webapps. But when it is deployed to FreeBSD machine, it
doesn't work properly Everything seems perfect, database url, and
servlet paths but when the same application is deployed to a
Solaris machine. It starts working again ...

Does GWT application depend on OS?

Re: how to set default button?

[Danny Schimke]

This, so I think, should work:

1. Your composite-panel-widget (which has 4 TextBoxes) implements the
KeyBoardListener
2. Every TextBox will get a KeyBoardLisener
(textBox.addKeyboardListener(this); // "this" is the Panel)
3. If "onKeyPress" is fired: check the Key, that was pressed. If it was
"ENTER" call the onClick()- method (Event) from the Button inside the
onKeyPress- Event.

If I understood correctly: you want to "simulate" clicking a button if the
user pressed the EnterKex while editing a TextBox...

Hope that was helpful...

Re: Who's Using GWT?

[ofrias]

We are using it at Trabber.com for the flight and hotel metasearch
results pages.

For us the best features are:
- you can forget about Javascript quirks
- efficiency (runtime speed, rpc speed, javascript size)

About the requested features, I know this is quite specific but we
would like to have a SliderBar with two knobs:

Thanks for the tool!

Re: GWTShell and facelet.

[olivier FRESSE]

Yes, all the needed scripts are here.
It seems that the GWTShell doesn't find the needed data to start of the GWT
java mode.
Really strange.
