Re: JSNI - Call Javascript native method from another
Technically, Here you are trying to call java method from javascript.
I did not come across this situation, try full compile if throws any
errors.

I'm getting an error saying dragStart is not defined.
Is there an special way for making this interaction work?

Re: onModuleLoad() - what is it in javascript
To answer my own question, looks like,
onLoadModuleLoad() - won't be converted into javascript as is.
It is a directive to java-javascript cross compiler telling what is
main script and how
rest of the scriptlets are to be arranged.

onModuleLoad() - what is it in javascript
Hi,
I am trying to figureout, what onModuleLoad() becomes after gwt
compilation.
Basically to figure out the magic behind onLoadModule.
All is well, java script gets loaded in head. But how on the earth any
function inside that script got
executed, are there any events, that Browser fires once script is
loaded?
I checked compiled code, here there suspects. I am not javascript
guru, can somebody throw some light on this.
schooldistrict.nocache.js is the main java script name for my GWT
app.
= here are three suspects ===
schooldistrict.onInjectionDone = function(){
scriptsDone = true;
$stats $stats({moduleName:$intern_1, sessionId:$sessionId,
subSystem:$intern_2, evtGroup:$intern_51, millis:(new Date).getTime(),
type:$intern_9});
maybeStartModule();
}
-
schooldistrict.onScriptLoad = function(){
if (frameInjected) {
loadDone = true;
maybeStartModule();
}
}
-
var onBodyDoneTimerId = setInterval(function(){
if (/loaded|complete/.test($doc.readyState)) {
maybeInjectFrame();
onBodyDone();
}
}
, 50);

JSON is equivalent to XML without tags not directly to java. Though java objects can be marshelled into xml and then to json. So I guess all collection types are converted into json arrays.

Re: Re : Developing GWT App using Tomcat
My short answer is develop in dev mode as is and deploy in any servlet container you prefer. If you go to debug configuration, in server tab, you only see embedded server which is nothing but jetty dev mode. In short there may not be any easy way to debug in other servers. But you should be able to develop in DEV mode and deploy in any servlet container. Once you make war file, there is nothing specific to jetty.

Re: Insane RPC Serialization Error.
I had similar issues, all pointed back to some defensive coding. As all calls are aync , behavior will be some what unexpected in few situations. Here are some tricks I played to such errors. 1) try in different browsers. 2) Load the app instance, then try, meaning use once, and second, third, is problem persistent. 2) In your loginConfig file, if is client side code, check for nullability of the object you are casting, sure, what ever object , you are are casting to is null, depending, how implemented the call, async call might be delaying. One trick, test for null and throw Window.alert(blah blah object is null at line and class - till you resolve these issues. 3) I had the habit of coding this.variable=param - this thew null pointer exception in IE9, I removed all this.variable and named params with non-conflicting name. Obviously javascript is not as robust as java, so we have code very defensively. 4) I found, rather I coded more procedural way than forcing all OO concepts in to code, this gave small footprint and performance. GWT likes procedure code. 5) Client side, I did not spend much time but Window.alert is working great for me. These are the things I should not see, if shows, code broke some where, even I kept these in app engine uploaded, of- course I don't have 1000's of users right now.

Re: RIP (Rich Internet Pages) instead RIA
Thanks Karthik for the reply. Client side rendering (DOM manipulation) and Server side rendering (HTML manipulation), certainly these achieve rendering efficiency, but still programming approach is still same, that client side event programming. Server can get away from rendering totally, keeping the business logic with it, and serve view+model+presenter to server, so that client can what it is best at, and server can what is best at. Creating event is the only way to get any resource from server in current GWT during run time. Please correct me , if wrong. Server could send entire page + presenter as as java script and Model to client, We can leverage Browser DOM, to apply Model to view as in today. That way you only serve the java script, really you need. Programmer can only visualize the page is in AJAX world, I have seen extreme apps, there is only single page, other extreme our jsp page with little java script. Code splitting, server rendering - makes different. But approach remains same, where client will have entire app and makes server calls on user events. We can get the best of both worlds, like every thing on server (jsp model) and every thing on client (GWT) model. Server should remain as brain for using Enterprise resources etc, that server will be able every thing that is need for client, for ajax page in one shot, Client can do DOM manipulation, little bit of event-ing if required, like refreshing with new values etc. Hand written AJAX page should be same as GWT generated page, that GWT will remain like tool, still programmer will have flexibility to choose what approach suits for his application. For few web apps, RIA approach may be more lively. Is there any easy way in GWT, to post entire page and get new page ?

Re: RIP (Rich Internet Pages) instead RIA
Thanks Magno Machado Paulo. You are suggesting to reverse the calls. Meaning first call RPC to load model then gwt async to load viewpresenter. second gwt async can be called only on success of first rpc for model. to make sure model is available in all conditions. So there are two async server calls no matter how we do it. more over code splitting is not transparent like individual pages, where you send which ever page you want filled with data to client. We should have flexibility to serve the page either from client or server, so that we can get advantage of both worlds. Every thing on client including decision making may not fit well for enterprise class solutions as all Enterprise resources are at server, which are well protected etc. It would be awesome if we get best of both worlds. -Venu http://schoolk12.appspot.com/ On Aug 6, 3:07 am, Magno Machado magn...@gmail.com wrote: You could use your server to fetch the data and embed it on the host page.

When this is the case for your application, then look into code splitting (http://code.google.com/webtoolkit/doc/latest/DevGuideCodeSplitting.html). That way you can serve only the code that is needed on the client. Used it in a recent project. Works very well.

Re: RIP (Rich Internet Pages) instead RIA
Thanks for reply Stevko. Meaning big javascript verses bunch of html pages. would it be great if some we combine these ?

Re: GWT Page flows - want to start a open source project - thoughts
I forgot to mention about JNLP based swing applications, I see lot similarities with GWT. Once difference is jar files will be downloaded instead of JavaScript module. Ultimate jnlp app runs in local jvm and makes some socket calls to server. for sure, JNLP addressed issue of client deployment. Though JavaScript runs on browser and makes ajax calls, I am not seeing web concentric approach. All these efforts are leading to P2P approach. If I have to compare web with network models , I would say it works like a start network model that way we can avoid any initial downloads, cache issues, script engine version issues (we got lot many jvm version issues with JNLP). Just like web page build with pure HTML pages, user experience should be same, no version issues, dll conflicts nothing. I would even go one step forward and ask why java to javascript compilation , why not java to 'html+javascript' compilation ? ( javascript for ajax). DOM api should be able to generate HTML directly, where there is no dynamic refresh, we don't need JavaScript. - venu - http://schoolk12.appspot.com/ On Jul 30, 6:24 am, dreamer venugopal.vasire...@gmail.com wrote: Very good point.

C:\eclipse\plugins \com.google.gwt.eclipse.sdkbundle_2.3.0.r36v201105191508\gwt-2.3.0\samples \Hello\src\com\google\gwt\sample\hello\client Without RPC or its variants, GWT is a pure client technology, as you mentioned runs any where javascript runs. On Jul 20, 9:02 pm, Dale12 dale.prat...@gmail.com wrote: I'm trying to build a basic packaged app. My understanding is that a packaged app doesn't require a server side. So, using GWT in Eclipse how do I set up a project without it automatically creating a server side package? Is it possible to use java's APIs when developing a packaged app (with no server side)? Take some of the games available for play offline, are they all written using only GWTs APIs and then compiled into JavaScript? I'm a bit confused on how this works which makes it a little difficult to ask well crafted questions. Any nuggets of info you can throw my way would be much appreciated. Also, if someone could point me to the source code for a fairly simple packaged app project that would be very helpful.

ui widgets - getValue() and getText() difference
Some of UI widgets has both getValue() , 'getText() and
corresponding setter.
Should we use value methods or text methods at least for text based
widgets.
value methods seems to be more generic and most of the UI widgets
seems to has these.
getValue has this aditional parse on top of getText() -
T parseResult = parser.parse(text);
What does parse do ?
=
public T getValue() {
try {
return getValueOrThrow();
} catch (ParseException e) {
return null;
}
}
/**
* Return the parsed value, or null if the field is empty.
*
* @throws ParseException if the value cannot be parsed
*/
public T getValueOrThrow() throws ParseException {
String text = getText();
T parseResult = parser.parse(text);
if (.equals(text)) {
return null;
}
return parseResult;
}

Re: Connecting to a oracle database with GWT
Eclipse plugin is a real good friend to figure out RPC. Just create new project choosing both app engine and gwt, creates a nice working sample RPC , hello world.

Re: TextArea - issues
Here is the test case.
1) Keep entering - lines will automatically break and goes to next
line - enter till you see few line
2) getValue()
3) store in datastore
4) get from data store and display in another TestArea.
Somewhere loosing line breaks ?

I'm not quite sure I fully understand the problem. But one thing to
watch out for is, that linebreaks from textareas are stored as \n and
or \r. To keep the linebreaks when displaying the text in a div, for
example, remember that you have to replace them with br/.

Re: my biggest problem with gwt

So I don't see a reason to choose various permutations and combinations. Looks that single path of bytecode-javascript-browser - is taking time.

Hi, We don't have to build the page entirely using GWT widgets, if playing these in any html is possible, it should be possible even with GWT. with HTML5 it is snap to implement this, but GWT does not prevent to launch player and play anything you want. Even you can mix Flash with GWT. You can build your site almost with 99% with pure HTML and just WITH one or two GWT widgets. Still it is GWT app. GWT is just a javascript, how much you want in your page, that is up to you. My wish is to go 100% and develop like in Visual Basic using GWT designer. May be couple of more years to realize this. Even add RPC/actions to buttons, should be under the hood, developer should add method, and just should declare, if it is client or server. GWT should take care. I have to come up with whole new proxy pattern to achieve this, to mask my client code. -Venu http://schoolk12.appspot.com/ On Jul 14, 1:44 am, Rob Coops rco...@gmail.com wrote: Then there is only one real solution, Adobe Flash... Pretty much everyone and their mother has a Flash Player installed (for those that do not use HTML5 (Apple iStuff is the main group there without Flash)). If you set the system to prefer HTML5 and then switch back to Flash if this is not available you are future proof and able to deal with what ever way that coin will flip. For the widget simply use two and load which ever one the users browser will support. If the users browser is capable to deal with HTML5 like Chrome or Firefox you simply load the HTML5 widget, if you are being visited by an older IE version simply push the Flash version over. Using MVP you would simply have to views and a few lines of code to decide which one to show the user not unlike deciding to show the user the mobile version of the view instead of the full fledged desktop version.

Re: comparing GWT and jsp apps - why javscript apps different from html apps
I think I should give little more explaining where I see, GWT may improve and become Visual Basic of web. For the moment if we forget ajax. When I converted VB application into web, I draw parallels from VB forms to HTMLs and developed as such, so flow remains same and user transition smooth. Now , when I am migrating web application with html pages to GWT, why can't we draw parallels ? like index.jsp -index.js page1.jsp-page1.js page2.jsp -page2.js Why can't we use same URI navigation from window to window as in web (REST) ? Sure, GWT is capable of generating java script pages. With GWT Designer we should be able to develop java script pages, without going under the hood. Why java script is coping as single module, why not as pages ? Why did we go from page (URI) concept to module, one java script bundle ? Sure there are techniques like code splitting, but programming concept has changed. May be some reason is there, or I did not understand completely. It is worth discussing so that we can transition our years of app development smoothly. -Venu http://schoolk12.appspot.com/ On Jul 11, 10:01 pm, dreamer venugopal.vasire...@gmail.com wrote: I had fairly large application developed in early web days , now I want to convert into GWT.

Re: Ways to reduce GWT compiled code size
Hi, Couple of tricks in personal experience. 1) Use concrete classes instead of interfaces, especially in case of collections, with interfaces compiler has to add all possible classes, as it does not which class at run time. 2) avoid iterators, use for loop 3) when we are using widgets - nothing much to do, but inside info may give little info, which is light weight, but reuse same widget in as many places as possible and avoid using all kinds of widgets, if no real reason.

I have another app, in which users are expected to visit all places. In this case code-splitting helps to reduce the initial load, but ultimately the entire compiled code has to be loaded. It is not a big deal for desktop apps (assuming good connection speeds), but I was planning to use GWT for mobile versions of these apps, and the compiled size scares me. So far it looks to me that GWT is not the right choice for a mobile app. I hope to be convinced otherwise. A native app with the same functionality will be many times smaller, but it's a lot of extra work to write a native app for each mobile platform. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How AsyncCallback works? - RPC services
