AutoBeanUtils.getAutoBean/ShimHandler.maybeWrap is causing JVM crash
We are suspecting that a notorious payload might be causing this crash. Yes, the JVM crashes after this exception.

Re: GWT 2.4.0 native drag and drop... does it *really* work with IE9?
we found that the drag and drop api is not usable at this point. There
is not a single browser in which this api work as expected. I think
the api is still in development and should not be used at this point,
unless you require part of it to work with specific browser.

How to handle custom server side exceptions
Hi, I am using gwt's bean validation framework for error validation. I am trying to understand the mechanism to create custom ConstraintViolationImpl in my server's service code and send it over to client. Following is my code in persist() method: SetConstraintViolation? set = new HashSetConstraintViolation? (); PathImpl path = new PathImpl(); ConstraintDescriptor? descriptor = null; ConstraintViolationPerson violation = new ConstraintViolationImplPerson(custom bean error, custom bean error, Person.class, person, person, person.getAddress(), path.append(name), null, ElementType.FIELD); set.add(violation); throw new ConstraintViolationException(set); on persist, I expect onConstraintViolation() of Receiver to be triggered. However I get the callback in onSuccess. What am I doing wrong here? Any kind of help and/or reference greatly appreciated.

Help designing app
Hi guys, I've read the docs and am itching to get started!! Still unsure about how to put the pieces together though. So lets say I'm building a site which sells products: 1. I have to display a list of products (divided into categories, each in their own 'pod'). 2. A basket that automatically updates as the customer selects products. What are the constituent parts I would need? I can see the initial 'drawing' of the screen and the 'pods' that would contains the products. Does the Product class have to be modelled twice? One for the front end and one for the server? Or is it a good practice to make it compatible with both? When the user selects a product (say the display of the product includes a checkbox), I need to update the product to show a tick in a checkbox (an image) and then update the basket. I don't want the basket to be tied directly to the onclick event of every product so I need to use the event bus concept? Not sure what the server calls would be in this situation though? Any help appreciated! Thanks R -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Questions about GWT suitability
Hi, knowing very little about GWT apart from the main headlines, I am considering using it for my upcoming projects. Others are criticizing this choice on 2 main points: 1. The application is not rich enough - the app is a shop where products are added to a basket and user details and payment details are captured. 2. Customizing the UI to the business requirements may not be possible. Does GWT constrain in any way how you style components?

Re: Million access to GWT Appl ??
You can either drive a nail using hammer or break some one's head! It really depends on how you use the tool; be it the hammer or gwt. as far as million access is concerned, it completely depends on your server if it can handle that load or not. Look into your server side code, server infrastructure, network limitations, etc. In your client code you should avoid unnecessary server calls. Or atleast try to club multiple calls into one(if practically possible). As far as sluggishness of code is concerned for big size apps, you should divide your app into modules, use code splitting, etc. If you compare gwt app with jsp based app: - jsp app will make server trip for every user application. example multiple paged data table. - data being transferred between client and the server is more in case of jsp, as the entire page has to reload. - gwt app is usually single page based. Server calls are only made for data. - gwt app can execute most logic on client side and use server only to persist or fetch data. - In a nutshell, a well written gwt app will always reduce your server trips and amount of data being transferred when compared to traditional jsp/struts based applications. If you compare gwt to other js based toolkits, they all behave similar as far as client to server communication is concerned. gwt only makes life simple for the developers.

Re: UIBinder Benefits?
uibinder separate layout out of your ui. pre uibinder we would use inner class to create hierarchy like structure for layout right inside java! That kind of code would look bit messy and unstructured to some one who is not familiar with the style of programming. As a developer, I would like to keep complete control with me and avoid more moving parts, especially non debug-able xml code! But in a way your java code looks much cleaner with uibinder. Since uibinder is responsible only for laying out your components, it nicely separates itself from the corresponding java class. Once you get used to it, you start liking it. When uibinder was introduced, I was hesitant myself but now I have adopted it. In fact I am craving for better support of some panels and widgets. Gwt programming is such that in most cases(unless you go out of the way) you end of creating not more than one or 2 pages of ui.xml files. hence uibinder files are very readable and usable! Infact my question is, why xml? why not yaml or json? Rakesh Wagh On Jun 20, 6:23 pm, spierce7 spier...@gmail.com wrote: Does using the UI Binder provide any benefits? I watched some of the I/ O conference, and it seemed like they made reference that the UI Binder using the browsers native rendering engine (or something like that), and it being a lot faster, but they didn't really specify whether that was the layout panels, or using the ui binder. What are the benefits to using the UIBinder, and where can I learn to use it? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Regarding GWT 2.0.3
Thanks Cerezo for the reply
I had opened web.xml file from xml editor but I
couldnt find any error. Can you check whether my web.xml format is
correct?

Try to open it with the xml editor of eclipse (design view) perhaps It has
an erroneus character (space, etc) and you can`t see it.

Re: MMLc: a Tool to convert HTML in GWT widgets
good job congrats! keep it up. On May 23, 10:59 pm, Davi Pires inho...@gmail.com wrote: Hi all, I'd like to announce that the tool I mentioned here earlier (6 months ago) has finally been opened. We call it MMLc. From the project description: MMLc is a GWT generator that processes files written in an enriched HTML like syntax and outputs code that instantiates the precise widgets to represent that code. MMLc improves collaboration between programmer and designers in GWT projects, bringing back to the designers control over UI and style. Programmers need only to worry with programmers's stuff, which is a Good Thing. We are trying to turn GWT into a more team-friendly tool. So far, within our team, we have achieved great success with it. Links: - Project page:http://code.google.com/p/mmlc/ - An about page that explains it all:http://code.google.com/p/mmlc/wiki/AboutMMLC - The original mail thread on this group:http://groups.google.com/group/google-web-toolkit/browse_thread/threa... - Some people asked for a comparison between this project and the UiBinder. We explain it better here:http://code.google.com/p/mmlc/wiki/ComparisonToUIBinder Some parts of the project (namely, i18n support and extensibility) still lack proper documentation.

Re: gwt webgl smartgwt
Use emulateIE7 in your html page. I personally had limited luck with this. Another work around is: frames. If your underlying layout is in smartgwt, load your canvas piece as different module html in a frame and vice versa. Both are really bad options, however smartgwt and gwt2 mix and match does not really work well!

Re: Can GWT do this?
ofcourse you can do that... It would help if you can elaborate. A simple implementation would be to make use of deckpanel where you switch the deck card based on editMode flag. put a label and textbox in the deck. If editMode == true, display textbox. if false, display label. This is one simple implementation. It depends on what your exact use case is.

Re: Creating a wizard - Series of steps with GWT
Steps: - Create a Composite widget called Wizard - This widget will have a DeckPanel and back/next buttons in a main VerticalPanel. - Add your screens(different widgets) into the base DeckPanel. - If you have lot of data that is shared across the screens, wrap it up in a value object. - Share this value object across screens. - Each screen is a composite widget that is aware of how to render itself with the passed data. you can make the wizard generic by accepting list of screen widgets (Widget[]) and adding them all to the deckpanel; on back/next move the visible deck as required. It is very simple! Little playing around with gwt and you will do it. good luck...

Re: Is it possible to clone Widgets?
It is not impossible, though not very straight forward;
To start with, you can create a simple replica of any of your widget
by flattening it into html, and creating element out of this html.
private class TestClone extends Composite{
public TestComposite(TestClone src){
setElement(new HTML(src.toString()).getElement());
}
public TestComposite(){
initWidget(new VerticalPanel(){
{add(new TextBox()); add(new CheckBox());}
});
}
}
...
TestClone original = new TestClone();
TestClone cloned = new TestClone(original);//Cloned!
This simple construct will work on basic Widgets that does not have
private variables and other handler related references attached to
them. Technically you should be able to achieve complete cloning if
you are able to link the html and its corresponding variable
references properly.

You're confusing key codes with characters. Key codes (as well as
keydown and keyup events) are really about keyboard *keys* that you
depress (or at least should be, as it differs a bit amongst browsers).
This was really confusing in GWT 1.5 and previous versions, since GWT
1.6 and the new events, it's a bit clearer, but still somewhat buggy
(see issue
3753:http://code.google.com/p/google-web-toolkit/issues/detail?id=3753

About Shandor Xul: Shandor allows you to write applications in a UI agnostic framework built on the Mozilla XUL declarative mark-up syntax. Shandor is not code-gen! It's a runtime framework with agnostic interfaces that you code against. There's an live abstract DOM representing your application that you can interact with and bind your code to. Below are some of the Killer things Shandor can do for you: Built-in Binding Framework (including collections to UI) Includes and Overlays (overlays allow runtime changing of the UI, free plug-in framework!) IOC ready (Spring, Juice, etc.) Groovy event handler support. Built-in i18n Being able to change a UI without recompiling is fantastic for our users as well as our Graphic Designers. Not having to write and maintain the same code in 3 places... dead sexy. Shandor has been of great use to us and we hope that it can do the same for the larger java community.

Getting started with gwt 1.6 and Intellij 8
hi all, I'm trying to learn GWT (well Ext GWT top be precise) and have lots of issues using Intellij. Firstly, I purchased a book but the examples are based on Eclipse. I'm trying to translate for Intellij but running into issues the main one being that Intellij doesn't seem to want to create all the directories for you. There is a demo on the Jet brains site but its out of date as the GWT Studio plug in has been deprecated. The new 'facet' system doesn't create a sample app. I did find a menu item when I created a new gwt project that said 'Sample App' but it said i needed version 1.5 of GWT or later but I am using 1.6 To top it all, I saw posts by the Jetbrains people to say 'proper' support will be available in Intellij 9!!! Bottom line, is it easier to just use Eclipse? Or is there some staright forward resource out there which will show me how to create a gwt app in Intellij 8? Frustrated!!!

I know very little about GWT and intend to read up soon but I have a question that I will probably not find in the docs and thought I would ask this group. My previous experience of testing guis has been prone to problems. The main one being testing lots of use cases and the build taking a lot of time to run. I was wondering whether it would be possible to test the GWT app with stubbed server-side components? Is that possible?

Re: Folks.. I need a direction
You are missing something here. and that is RPC. Calling get set on your beans will modify that value only in the client browser. You want to communicate this value back to the server. So you need to make an RPC call. Now, you can generate a bean that will make RPC calls in its get set methods... why not? However, there is no such library or framework currently that work this way. With little code, you can create this behaviour. However I will recommend that let a bean be bean. do a rpc when set is called on the bean. Send the entire bean to your service layer. In service layer make the db call.

Re: Why not use applets?
Weak reference (Weak listener in SWT/Swing) that isn't supported in javascript, but does in javaFX (java). You can simulate this in gwt. About speed and performance: Remember js runs inside the browser. It is completely at the mercy of browser(unlike applets). You should see the js engine improvements in firefox 3.1 and chrome. They are ultrafast for js. Js differs from pure java in the sense that it is single threaded. However this will change in coming years. We recently developed a sizeably big application using gwt over the past 1.5 years. I can tell you that without any code for freeing/releasing/ cleaning up objects etc, we had pretty good performance... If I am working with browsers, my first choice will be browser dom and not plugins! GWT makes so much sense with that aspect... As I said earlier, google should submit the gwt as a jsr in jcp. Or sun enggs should rethink for client side java. Again, translating java into js or any other code that runs on client would be better than forcing the jvm/bytecode approach. And I say this after writing my first ever web based program as java applet and not jsp/aps/servlet or cgi script. On Mar 31, 4:02 am, Ed post2edb...@hotmail.com wrote: - New scripting language. Why?

And don't worry, you can still do a lot in java, and javaFX looks a lot like it. If you are a swing/gwt programming, it has some reay nice things like for example the bind keyword. Just one keyword to bind a variable to some screen presentation. I gwt, you have to use a listener, listener collection, etc... to realize this (and clean it up properly to overcome memory problems).

Compare it with Flash... it simply doesn't fly. Flash's main advantage is animation and vector graphics which is not captured properly by javafx. I can go on and on... The point here is that if sun is coming up with a client side tech(browser based or otherwise), it should 1. try to bring in something better in comparison to the competition and 2. Learn from its past mistakes(pushing applets and java run time in client machine). Disclaimer: I have not developed a real application from javafx. My knowledge is restricted to samples and demos provided by sun. I wonder why google-gwt team didnt register a jsr for gwt? Browser is getting faster and feature rich. Java should make browser work to its advantage. Sun's approach is isolation... it wants to get out of the browser into its own jvm to do things. Html 5 is so exciting. Imagine a swing based application rendering in HTML5 canvas! As I said earlier, Sun should think out of its jvm/jre mind set at least for client apps. Silverlight: Not much knowledge/experience in that area. I will go with flash instead of Silverlight any day(another discussion!)

Re: Why not use applets?
My thoughts on javafx: - jnpl start: Web apps are supposed to run in web browser! More over they are supposed to co-exist with other stuff on the webpage, example javascript, html. While I like the concept of webstart for deploying desktop based applications through internet, I dont really buy the idea of calling a webstart based app as RIA. I would rather call it as desktop based swing app with a different skin! - New scripting language. Why? Why should I learn a new scripting language? I love java... and sun is asking me to write my code in something else? why? Who is sun targeting? Developers or designers? or both?? I am confused here... JavaFX Script is a big no no for me. - Its not cool enough! Java fx would had been cool if it was released in early swing days, not now. It is not smooth enough. It is not catchy enough. Compare it with Flash... it simply doesn't fly. Flash's main advantage is animation and vector graphics which is not captured properly by javafx. I can go on and on... The point here is that if sun is coming up with a client side tech(browser based or otherwise), it should 1. try to bring in something better in comparison to the competition and 2. Learn from its past mistakes(pushing applets and java run time in client machine). Disclaimer: I have not developed a real application from javafx. My knowledge is restricted to samples and demos provided by sun. I wonder why google-gwt team didnt register a jsr for gwt? Browser is getting faster and feature rich. Java should make browser work to its advantage. Sun's approach is isolation... it wants to get out of the browser into its own jvm to do things. Html 5 is so exciting. Imagine a swing based application rendering in HTML5 canvas! As I said earlier, Sun should think out of its jvm/jre mind set at least for client apps. Silverlight: Not much knowledge/experience in that area. I will go with flash instead of Silverlight any day(another discussion!) Finally: I think javascript and HTML5 is the future of Internet based applications. With that said, any technology that works in that direction is a good technology. gwt, gears, canvas, netscape browser itself, etc ... all are going fwd technologies Rakesh Wagh On Mar 29, 10:35 pm, Guy Rouillier guyr-...@burntmail.com wrote: On Mar 29, 9:46 pm, Rakesh rake...@gmail.com wrote: oops, forgot to mention: javafx is such a wrong initiative and waste of time energy and resources in wrong direction!

Re: Dealing with session timeout and container managed security
we use server push for session time out and it works really great! On Feb 28, 1:26 am, marcelstoer mar...@frightanic.com wrote: Is there some consensus or best practice in the GWT community as for how to deal with session timeout and container managed security? There are some pointers if you search for this subject, but some of the ideas are wild... In my case I use the Servlet container's built in security features for authentication as described in the Servlet specification. Hence, in my web.xm I protect access to the GWT application like so: security-constraint web-resource-collection web-resource-namemy app/web-resource-name url-pattern/app/*/url-pattern http-methodGET/http-method http-methodPOST/http-method http-methodPUT/http-method http-methodDELETE/http-method /web-resource-collection auth-constraint role-name*/role-name /auth-constraint /security-constraint login-config auth-methodFORM/auth-method form-login-config form-login-page/public/login.jsp/form-login-page form-error-page/public/login.jsp?retry=true/form-error-page /form-login-config /login-config security-role role-name*/role-name /security-role So, the application (host/bootstrap page, RPC Servlet, etc.) is in the app folder and the login form (login.jsp) is in the public folder. This works flawlessly except for the session timeout use case. The application sends an RPC request to /app/AppServlet, the Servlet container requires authentication because the session had timed out and dutifully *forwards* to the login page. Hence, the result of the request is not some RPC/JSON/XML object as expected by the client but the login page HTML structure. The client simply isn't prepared for that and freezes i.e. doesn't do anything. I believe that on the server side everything is set up correctly. If the session timed out the requests don't even reach the RPC Servlet because it's intercepted by the container, fine. But how do you deal with this in the client? Should one write some custom AsyncCallback class that handles the reponse sent by the container? Thanks for your feedback.

Re: What are you using for a backend??
php and perl are light weight compared to j2ee stack. Tomcat php perl linux hosting is usually cheap because all the software required are free; also the hardware requirement is relatively low. Because of these advantages, over the past years a vast community of small and medium size applications has been developed around these software. It is relatively easy to setup and support a hosting service with php- tomcat-mysql combo. Moreover there is a huge open source domain that has various libraries and applications written in php. I am sure, you will find java-tomcat/jboss based hosting service but the fee will be much more when compared to those php deals. Try the Amazon cloud computing platform. I have not tried that myself, but it sounds promising.

Re: Multiple web pages how-to
You are still thinking in the classical web development paradigm. You should start thinking web2.0 now! The concept of multiple pages and they linked with each other through form submits or hyper link clicks etc is gone now! Now your entire application is a module with a single entry point and it loads in one single page. Once loaded every thing happen in that same page... popups, tabs, button clicks, hyperlinks, form submits, table render, data fetch, insert, updates, etc, etc all happens in that same page. However, as per gwt's philosophy you can break your application into multiple functional groups called modules. Modules will load in separate pages and can link to each other using classic hyperlinks or other methods. But for most purpose your entire application will be one page! With that said, there is no default back/ fwd or history related functionality build in your application as you are not navigating through data any more. To accomplish this behavior, gwt has provides History api. You can use the History api and events to simulate the back/fwd and bookmark functionality. It is a little tedious, but the good news is you get all the control over difficult to manipulate browser functions. I am sure you will learn these concepts through practice. Hope that helps!

Re: Newbie Question on GWT/JSON
You probably got your answer by now. Think this way. JSON string is like any other string. The transport mechanism does not have to know weather it is json or text or number or binary or otherwise. With that said, you can use forms with get or post(knowing the advantages drawback of each will help you select the right mechanism) and simply posting it to your php page. In your php page, read the request parameters as if they were any other parameters. As a matter of fact you can even append the json string as part of your target page url with a variable name and expect the json string (with a hyperlink click) to reach its destination as expected. Good luck!

Re: about GWT compiler performance
some quick tips:
1. Hardware: U need to increase your CPU power over memory. Adding
gigs of ram is not going to help much. Instead use dual/quad
processors with higher configurations. Also use a faster HD and a
higher FSB(try to match with your RAM speed).
2. Compile for one browser using user-agent mentioned earlier.
3. Code design! This is the biggest area where you can speed things
up. Use lazy initialization in every possible class. There are many
threads that explain this concept. I will give you a quick example:
public class MyPopup extends DialogPanel{
public DialogPanel(){
...
}
private void initialized = false;
private void init(){
setWidget(createWidget());
}
@Override
public void show(){
if (!initialized){
init();
initialized = true;
}
}
}
With the current GWT toolkit #3 is your key to significantly reduce
the load time. It also makes your application design better.

Re: IDE for GWT
Eclipse vs netbeans vs IntelliJ is actually matter of personal preference and any such comparison should probably be part of some other forum. None of thes IDE I believe has anything out of the box for GWT. And even if they did, most of those features are easy to do manually(of course with little practice). As far as application builder, project builder and drag and drop facilities are concerned, they are all beginners tool. For example, creating a debug/run configuration is matter of knowing what jars to include at runt time and what parameters to supply. Doing it manually some times is much simpler than running the creators! If I change or add a RPC method, changing 3 files is hardly a matter of few more seconds. As far as visual designers are concerned, I would recommend: Design the code such that it loads fast in hosted mode(use lazy initialization of objects, you can find many threads out here). This way you have complete control over your design/code and whatever changes you do, will be seen immediately in hosted mode on refresh. Again, all the assistance tools are good for beginners and small size application... but as the application grows, you are most of the time pretty much on your own.. and it is good to be that way so that you have the complete control and less unknowns. Any tool that helps you write java code should be equally helpful for gwt. vi ny1? ;) :) just my 2c.

Re: Get file from server with GWT-RPC
Cannot comment on what you are doing wrong without looking into the code. However I see no need for setUrl on server side. You should have a Servlet that will parse the parameters, read the appropriate image file(either file system or db or any doc mgmt system for that matter), set a proper content type and just spit out the byte stream. From the client just call this servlet with appropriate params for it to retrieve the image.

Re: Waiting on multiple RPC calls
performance: Are you acquiring handles to three different RPC services for your 3 calls? If yes, you can improve performance by clubbing them into a single call. If you do a little client side profiling, you will realize that creating a async reference on client side is a not a very quick operation. It is always a good idea to cache(static) your rpc service references on client once you create it for the very first time.

Re: How to share work between Java developers and HTML/CSS designers?
Here are few things to consider: - Check the Instantiation Designer tool. Personally never used it beyond evaluation... but you and your team might have some luck with it. - Let the HTML team design the layout. Let the GWT team design the application and place the components as per the layout. Gwt team uses the default widget css. Then let the HTML team work only with the css provided by the gwt team and modify it to meet the new look and feel. - GWT team takes both the layout and the CSS from html team, and include the CSS element as the project progresses. Finally this is what we did: - We created our own widget library with common components for tables, hyperlinks, menus etc. We(developers) spared some time designing the common components as per the graphics design. Finally for most of the part it was only the matter of following the layout. good luck!

In my experience we had good luck and happy results using listeners to decouple our widgets and hence screens. Basically like any other java based application you need a lead in your team who will always take care of the over all design and make sure that listeners are not abused; that parents do not pass themselves as references to the child for purpose of method invocation; and many other best practice that come by little practice. Withgwt, client side programming deserves equal or more respect(hence design and lead resources) compared to its server side counter part. About the size of generated javascript code. As I said I am not going to go in comparison with any other lib, because that would be apple vs bananas(I love both fruits btw). If your app is compiled as 160kb js, I think it is not huge. It is probably just okay. The best thing I like aboutgwtis that it does not include a staticgwt.js of its own (like most other toolkits does, take dojo for instance).Gwtmaps your java code as effeciently as possible to corresponding javascript(again without including its own static js lib). I agree with you that lazy loading would be a good idea. Moreover I also agree with you that hosted mode refresh time sucks as your app size increaseas(and that happens pretty soon!). We all face this issue, and I think thatgwt team will put a solution in coming months. See my comments in this thread:http://groups.google.com/group/Google-Web-Toolkit/browse_thread/threa...

A good example is managing administration activities could be a separate module. This way you take away the load from main application. 2. Create a separate project for commongwtwidgets. If you are relying on vanillagwtfor widgets(not usinggwt-ext etc), you would most probably end up writing lot of common widgets that you would like to reusein your project. We created a separate project just for this purpose. So whenever we write a reusable(1+ times) widget, we go to this common project, do our development, test it in hosted mode(with a demo app) and just include the js. This way we shift at least 30% of our development to this very small project that is easy on hosted mode refresh, debugging, and over all development.

Re: Why use GWT?
Adam, did you even try GWT? Because if you had developed a 3-4 screen application with server connectivity you would have already answered your question. I will not do gwt-jquery comparison here, but just few cents about gwt itself. That who is using list is incomplete. I can bet you that gwt's who is using list(if honestly made) will be bigger than any other ajax tech adaption. Jquery's adaption list is created by jquery itself. gwt's list you posted is not created by google or the gwt team. FYI, we have done more than 3(big) projects successfully overt the past 2 years and we do not care to be part of any such lists. GWT is more than a UI library, it is a paradigm shift in developing web applications. People who have spend there life in struts and other similar web based framework will typically take a while to understand this paradigm change. If you liked and respected swing and javascript for what ever they are, you will probably like and understand gwt much faster than some one who doesn't. Very fast, here are some basic advantages that make gwt a toolkit of choice: - Google's beta releases are production quality! - You get answers to your question within 24 hours from a great user community. Like you just did for this thread! - Apache, A great license, without any fine prints. - Dozens of supporting projects, which make GWT even better. - Check smart gwt or ext gwt for really rich widgets. - Couple gwt with spring and hibernate and with little plumbing you are dealing with only java objects from client browser to the data layer. - A very small technology and tool stack required for the entire project. - Generated js is super-super fast and tiny(relatively)! You end up writing fast and small apps. compare it with flex and or any other toolkit of your choice. (btw, comparing it with lo level libs like prototype.js is wrong) - Every thing is so modular and object oriented. you can write long lasting apps and manage huge application easily. - Creating reusable widgets is a snap. And that is what you do with gwt most of the time. - Some really great features that are unique to gwt: locale mgmt, history token management, image bundle, exception handling and rpc mechanism - I am yet to see a more elegant and easier way to communicate data back and forth the server then gwt's rpc. You send a generic arraylist to your client code. You cannot beat this! - Strongly typed java is always better compared to js. You end up making less mistakes as 80% errors are resolved by eclipse as you type your code. - Never seen a better way of debugging my code. - Listeners architecture(if you understand and implement correctly) is a great tool to decouple your app widgets/classes and make them more reusable. Great way of event handling! - Can keep going ... all in all gwt rocks!! Fine prints: There is a learning curve if you really want to build long lasting production ready code(depends on your java experience and understanding of swing, layouts, event handling etc).

Re: SWFUpload library for GWT
While I appreciate your efforts: We recently were faced with a requirement with multiple file upload. After lot of research and trying out swfupload we concluded that the best approach(for now) is using gears Desktop api for this purpose. swfupload had huge problems with flash 10 release. Basically adobe decided to change the way multiple file upload is handled for security reasons. In my experience there is no silver bullet as far as multiple file upload functionality is concerned. Nothing against swfupload, it is a great library in its own rights. But flash in my experience is not reliable/credible enough for this specific purpose. People might vary in opinion and I totally respect it.

While work continues on GWT support for file uploads using Gears, I need a more compatible and short term solution to a problem that's come up. I also feel that having more than one option is good practice to ensure compatibility with the most number of users. I'm currently putting this together for my own needs but I wanted to see if anyone else in the community would be interested in helping to complete this. The SWFUpload javascript library is around 30KB and and the associated flash control is 11KB. It's also recently had support added to work around the new security restrictions in flash player 10 (which is what has forced me to scrap my own implementation and move to this one). My goal is a nice GWT wrapper to make it very simple to drop into any existing GWT app. To my knowledge no such thing exists yet (please speak up if you know of one).

Re: Why use GWT?
I will agree on the final thing about listeners and feel that it is more of personal preference. In my experience we had good luck and happy results using listeners to decouple our widgets and hence screens. Basically like any other java based application you need a lead in your team who will always take care of the over all design and make sure that listeners are not abused; that parents do not pass themselves as references to the child for purpose of method invocation; and many other best practice that come by little practice. With gwt, client side programming deserves equal or more respect(hence design and lead resources) compared to its server side counter part. About the size of generated javascript code. As I said I am not going to go in comparison with any other lib, because that would be apple vs bananas(I love both fruits btw). If your app is compiled as 160kb js, I think it is not huge. It is probably just okay. The best thing I like about gwt is that it does not include a static gwt.js of its own (like most other toolkits does, take dojo for instance). Gwt maps your java code as effeciently as possible to corresponding javascript(again without including its own static js lib). I agree with you that lazy loading would be a good idea. Moreover I also agree with you that hosted mode refresh time sucks as your app size increaseas(and that happens pretty soon!). We all face this issue, and I think that gwt team will put a solution in coming months. See my comments in this thread: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/604aec6b7460c133/950c73ed1d98ae3a?hl=en#950c73ed1d98ae3a Here are some suggestions: 1. Use modules right from the beginning if possible. If you could divide your project into distinct modules that do not rely on each other, do it! A good example is managing administration activities could be a separate module. This way you take away the load from main application. 2. Create a separate project for common gwt widgets. If you are relying on vanilla gwt for widgets(not using gwt-ext etc), you would most probably end up writing lot of common widgets that you would like to re use in your project. We created a separate project just for this purpose. So whenever we write a reusable(1+ times) widget, we go to this common project, do our development, test it in hosted mode(with a demo app) and just include the js. This way we shift at least 30% of our development to this very small project that is easy on hosted mode refresh, debugging, and over all development. I hope you get my point here. 3. use lazy initialization of variable where ever possible. This reduces lot of start up time. 4. At time of development compile only for IE(through a property in gwt ex More over we created a entirely different project that would contain the common widgets that we develop and can be reused. I think Finally: - I reiterate, it is futile to compare gwt with any other js libraries. For us, gwt eliminates the use of many server side layers and xml configurations etc that we would traditionally do in a struts like app framework. - If I am allowed to be philosophical: GWT is a change in paradigm for web app developments - It also makes our server side code simple to a level where we have to just provide the implementation to a bunch of interface methods. Our server and client teams can work totally independent of each other. - Moreover when we float requirement, all we need is a person who is good in java, and nothing else.(yes there is a learning curve for this person, but that is true with any thing else). - Before gwt, javascript was my personal favorite for the flexibility and ease of that language. However it didn't take me to long to realize how nasty it would get to debug others code and how difficult does it get to add new features to a already written js based application. Frankly it is a nightmare and ppl tend to stay away from touching pre written js based applications. - Last year we developed a gwt based application and shipped it offshore for maintenance and the response from our offshore team was really good(compared to our earlier experiences). All were new to gwt but they could go in and do bug fixes and add new features without much hand holding(and without hating or messing the existing code).

My most recent one (still in development) is matchomat.com. This application has some rollover buttons, dialogs, form checking, gwt rpc, history, and it even uses gwt-coded jsonp to communicate with an erlang server. All of the js is written in GWT. I described the client- side architecture in the reply to Adam T earlier in this thread. I've also made a large pure-GWT-history app before. created by jquery itself.gwt'slist you posted is not created by google
Re: Your opinion sought: Jetty or Tomcat?
jetty or tomcat, no problem for us. But startup speed certainly is! we use -noserver with jboss/oc4j and weblogic. Few thing I would like to propose/request in upcoming release: #1. Seamless hot deployment for any source code change(class signature as well as stmt changes). So when the user refreshes the browser, js compilation does not take place. it will just load whatever exists. Hot deployment will make sure that whatever exists is always current. I know this is difficult to achieve but if it is implemented, the development time will be super super fast. We will basically have to run the app in hosted mode browser only once. And all subsequent changes will be auto deployed(synched) with the hosted mode. In big applications like ours, almost every code change requires hosted mode refresh. And in most cases it takes any where between 50 to 200 secs. #2. If #1 is not possible: gwt should atleast detect the files that were changed since app was last refreshed and attempt to compile load only those changes. Some how the compiler/loader/linker should be smart enough to the level where hosted mode refresh is reduced to less than 7 seconds. Really looking forward towards a super fast hosted mode.

Re: SmartGWT 1.0 Released
great job Sanjeev. Keep up the good work. Always love smart-client. Smart client is much better compared to ext-js as far as licensing is concerned. However the showcase looks little slow compared to the original js based smart-client as well as gwt-ext. Thanks!

Gears distribution for completely offline clients
First of all, please forgive me for posting this topic in gwt forum. I have tried posting threads in the gears group with no real response. Basically I am in desperate mode and need advice from people knowledgeable in this area. I believe many gwt users use gears and might have faced similar issues. We are facing a scenario where some of our application users will never have access to public internet. However they will be connecting to the corporate intranet to access the application. Now we are almost in final stages of our application development that heavily made use of gwt, gwt-api and gears. Recently we discovered that gears does not have bundle-able plugin. We cannot go in production without addressing this issue. Currently we are trying to make a exe from the gears svn trunk. I would appreciate any kind of feedback and or suggestion from experts. Thanks in advance. Here is the issue thread i created in gears: http://code.google.com/p/gears/issues/detail?id=763sort=-idcolspec=Version%20Milestone%20Owner%20ID%20Summary%20Component --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
