Re: Your opinion sought: Jetty or Tomcat?
I personally use Tomcat a lot more, mainly because it started as the reference implementation (though I know it no longer technically holds that position). The few times I've wanted to use Jetty I've had to switch back to Tomcat due to lack of system admin knowledge (ie: the various admins I was working with didn't know it). That all said, I almost never use Hosted Mode, and system admins don't have to deal with a development time engine. Tomcat does have much better IDE support than Jetty, but since Hosted Mode is in charge of that, again it makes no real difference. When I do run Hosted Mode it's with the -noserver option. So my end opinion: I think the change is a good idea, since the additional speed and lower memory load will encourage people trying out GWT for the first time. Tim wrote: jetty is awesome. In their latest drop (6.1.12.rc2 and rc3) there is a new feature in maven-jetty-plugin to reload jetty on keyboard events in console rather than automatically - it's indispensable when java GWT code lives in the same source tree as the server side java code (just in different package). And generally, maven jetty plugin is way better than Cargo stuff that's used for Tomcat. Also, Jetty Continuations are just some much easier to work with than Tomcat's Comet. No wonder they are including it into Servlet spec 3.0. Nothing particularly wrong with Tomcat but I think it's just lagging in terms of developer productivity features behind Jetty.

Re: Using Selenium for GWT tests.
Thanks for the information and references to your blogs, Dan. Really helps. If somebody is looking for a way to set ids to GWT widgets UIObject.ensureDebugId(Element, String) is supported starting GWT 1.5 which greatly helps in integration with Selenium using object identifiers. The best part is it results in no compiled code in production environment. You would also like to to have a look at onEnsureDebugId -Siva. On Oct 10, 7:36 am, dan [EMAIL PROTECTED] wrote: Hi Siva, I used Selenium on a project to do integration tests of a GWT application; it worked pretty well. We didn't run the tests in hosted mode, we ran the tests in web mode deployed to our application server. The trick was remembering to use the waitFor Selenium commands to avoid tests intermittently failing due to race conditions -- this is true for all Ajax applications. As for testing an application, if you're talking about unit tests, I've written an article on writing GWT applications test-first that will appear in the November 2008 issue of Better Software. This is an excellent blog post on GWT TDD:http://robvanmaris.jteam.nl/2008/03/09/test-driven-development-for-gw... I've written a blog post about how and when (and why you shouldn't) test GWT widgets:http://blog.danielwellman.com/2008/06/strategies-for-testing-gwt-widg...

Re: Your opinion sought: Jetty or Tomcat?
I use Tomcat for all our customer deployments and as a server to host the development. If Tomcat is used as the server for development, there are probably less chances that something would not work when deployed. I am not sure of how popular is Jetty for real deployments compared to Tomcat, but I have the feeling that Tomcat is ahead of Jetty. The startup time in development mode is not really important for me, considering that there are not that many cases where the server needs to be restarted. We don't use any specific feature to a particular server, so Comet or continuations are not in the balance. A few weeks ago I deployed successfully a GWT app on Tomcat on a Windows server in about 30 mins. It still took me about 1 day to do the same on Ubuntu, not because of GWT, but because of the way Tomcat is configured by default on Ubuntu. Since it was the same server from beginning to end, I had less to investigate. If it was another server engine, I would have doubts on many more configuration issues. I am looking at the Widgets and the incubator and I wish a lot more work was done there. Lots of customers and developers have ext on their lips, I'd like to see more development in that area.

Re: Your opinion sought: Jetty or Tomcat?
I think it is broken in the sense that it does take a lot of time to get the app running when in development mode (and hosted mode), or at least more time that I would like it to. I would welcome Jetty if that improves the performance. I have nothing specific to tomcat so far, so nothing should be broken.

Re: GWT + iText + Eclipse Problem
The content type is correctly set from the server, as I can see from the firebug logs. If I make the browser pointing to the correct address, the pdf open/ save dialog is showed and everything works fine. But, if I make a request from within gwt, the callback mechanism seems to override the normal behaviour of the browser. Do you know if it is possible to make a standard HTTP request from gwt without using callbacks? On Oct 14, 1:48 pm, Paul Robinson [EMAIL PROTECTED] wrote: Security prohibits javascript from direct access to the filesystem. You could make the same HTTP response you get when downloading a file from any web server, so the browser (rather than javascript) shows the save pop-up.

Working off of http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5t=FAQ_HostedModeNoServer, Hosted Mode hooks in appropriately (changing Java code and refreshing the Hosted Browser changes content).

You're use GWT RPC, which means you have a RemoteServiceServlet somewhere that implements the server side of that RPC service. You need to compile that servlet to a Java .class file and deploy it to your web server. You also need a web.xml file to map request URLs to your servlet.

Re: -noserver 1.5 RPC Help
You'll want to set yourself up with a proper build process. I suggest Ant. It's simple, powerful, and there are a number of examples you can borrow from this forum. Have your Ant script build a .war file and copy it to your tomcat/webapps directory. Tomcat's default configuration is to automatically deploy any .war it finds in webapps. No server restart required. On Tue, Oct 14, 2008 at 1:18 PM, Christopher Venning [EMAIL PROTECTED] wrote: Thank you very much.

Late-loading parts of a GWT app
I've seen a number of threads about GWT apps that are comprised of multiple modules. Because the modules are compiled separately, though, there's no code reuse between them. If we could give the GWTCompiler all of our modules at once and specify the load order constraints that we'll enforce, then it should be able to avoid duplicating code from earlier modules in later modules. This way our app can have lots of great but rarely-used functionality that users don't have to wait to load up front. Would others like this? Is it in the works?

Deploy GWT Project to Tomcat
Hi! I'm actually trying to deploy my very first GWT Project StockWatcher, just like in the tutorial i found on googles website. I can deploy my .war to the tomcat and visit the page. But when it comes to servlets, the server is throwing exceptions. So here is the code, i copied everything from the tutorial, so its pretty much the same code, so i only will post here the intersting parts: in the stockwatcher.gwt.xml i mapped the servlet like this: servlet path=/stockPrices class=com.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl / I dont know why its /stockPrice and where this is leading to. But in the tutorial there is one more file with this strange value: StockPriceService.java in the .client package: @RemoteServiceRelativePath(stockPrices) So what i am actually doing here? I cant get through, why i post his. The tutorial does not make this clear, imo. Whats so ever: i run the project in eclipse: it works. I compile the project: it works. Now i try to create a .war file, first i copy all the files in /www/ myproject.something/ to another folder. In that folder i create a WEB- INF with classes (inside no other folders, just the StockPriceServiceImpl.class) and the lib (inside gwt-servlet.jar). And here comes the web.xml (correctly saved in WEB-INF): servlet servlet-nameStockPriceService/servlet-name servlet- classcom.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl/ servlet-class /servlet !-- Standard Action Servlet Mapping -- servlet-mapping servlet-nameStockPriceService/servlet-name url-pattern/stockPrices/url-pattern /servlet-mapping /web-app So the url-pattern is just the same, as it is in the .gwt.xml file / stockPrices. And the servlet-class com.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl is just the same as you would find it in my project ... (but the .class file is directly saved in the /classes/StockPriceServiceImpl.class - this is correctly folder? ) But when i deploy the .war file to tomcat. It just cant find the servlet. I get HTTP Status 404 - Servlet StockPriceServiceImpl is not available message. :( Maybe the Tomcat is wrong configured? Any help??

GWT Session problem
I use the following method to get session ID in my
[RemoteServiceServlet] class:
protected String getSessionId()
{
return getThreadLocalRequest().getSession().getId() ;
}
It used to work nicely. Then all of a sudden, it started returning a
different ID with every call. I use tomcat 6. I have tried switching
to the latest version of tomcat, then tried both IE6 and Firefox 3
with the same result. Any idea what the issue could be?
I understand that I could get and return the ID on the first call and
pass it back to the server as a parameter with each subsequent
request, but that's a lot of extra work and also defeats the purpose
of session management.
Thank you.

Re: GChart: Can i have gray dotted gridlines and solid axes?
Sorry, you cannot style a client-side GChart's gridlines. You can use the setGridColor method, which may help do part of what you are looking for: http://gchart.googlecode.com/svn/trunk/doc/com/googlecode/gchart/client/GChart.html#setGridColor%28java.lang.String%29 If you must have dotted gridlines, and don't mind a bit of extra work, you can add a curve with a SymbolType of YGRIDLINE (or XGRIDLINE) add points at the y-coordinates where you want to draw the gridlines, and use setBorderStyle(dotted) on that curve, and appropriately change its width, height, etc (basically, you will be drawing your own gridlines via a special curve; since curves have more options, you can get more varied gridlines). Thanks for your question. If you think more gridline options are needed, please consider submitting an issue to the GChart issue tracker. John C.

You can even use advanced features such as adding GWT widgets to the Map, creating custom overlays, custom map types, and other components. The Google API Libraries for GWT http://code.google.com/p/gwt-google-apisproject is a collection of libraries that provide Java language bindings and API specific plumbing for some Google JavaScript APIs. The goal is to make it easy for developers to use these JavaScript APIs with GWT. This release of the Maps http://code.google.com/apis/maps library complements the recent release candidates for the Gearshttp://code.google.com/apis/gears/, Gadgets http://code.google.com/apis/gadgets/ and the Google AJAX Searchhttp://code.google.com/apis/ajaxsearchAPIs. With this set of release candidates, each library is now distributed separately so that you can downloadhttp://code.google.com/p/gwt-google-apis/downloads/only the specific library you are interested in. We encourage you to try these release candidates out and give us feedback, either through the issue trackerhttp://code.google.com/p/gwt-google-apis/issues/liston code.google.com, or through the Google-Web-Tolkithttp://groups.google.com/group/Google-Web-Toolkitor Google-Web-Toolkit-Contributorshttp://groups.google.com/group/Google-Web-Toolkit-Contributorsgroup. - The Google API Libraries for GWT Team -- Eric Z.

Re: GWT 1.5 on Java 1.4
Hi CFS, I think the biggest problem to look at is whether the GWT 1.5 RPC mechanism uses Java 1.5 syntax server side (and since e.g. it serializes generic collections, it must do). In which case your RPC servlets probably won't run and you'd have to look at e.g. JSON to communicate with the server. I don't believe you can't mix GWT 1.5 RPC client side code with the 1.4 version of gwt-servlet.jar server side. regards gregor On Oct 14, 11:14 am, CFS [EMAIL PROTECTED] wrote: Hi, Is it possible to run the server side part of an GWT 1.5 application in a Java 1.4 compliant container?

Re: GChart and Maven 2
Appreciate the complement. I understand that a Maven2 repo makes it easier for Maven2 users to include GChart as one of their project's libraries, but I have not a clue as to how to set up a Maven2 repo. So, unless its really easy to set up a repo if you've never used Maven2 before, or unless someone who knows how to set up a repo volunteers to do that (or to tell me how to do it) for Client-side GChart, it won't happen any time soon (I've really got my hands full right now trying to figure out how to properly integrate GWTCanvas' capabilities into the product) Sounds like a great idea, though, so please add it to the Client-side GChart issue tracker.

Hiding a custom Widget and then showing does not work anymore
Hi all GWTficiondos I am working on a rather complex environment (say OS) based on GWT. I use a widget based on SimplePanel which owns the real widget to be shown. My problem is that after hiding that outer SimplePanel once i can not get it to be shown any more at a later stage. I show the widget with the following code: child.setVisible (true); this.setVisible (true); setStyleAttribute (this.getElement (), visibility, ); setStyleAttribute (child.getElement (), visibility, ); child.setUserAttention (true); Hiding: child.setUserAttention (false); //child.setVisible (false); //this.setVisible (false); setStyleAttribute (this.getElement (), visibility, hidden); setStyleAttribute (child.getElement (), visibility, hidden); If i hide again, the code in my widget runs (background process display some info somewhere else) but the UE is now shown after setvisible (true);. All the HTML ist there. What do i miss here? cheers Jürgen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT + JSON + Server-side code....... RPC ???
Hey people,
I'm not sure if I understand this correctly and figured I could use
some help. I have an existing Java Struts based application that I'm
trying to integrate GWT as a module into. I created some simple client
code and wanted to make a call to the server side to see if it would
work fine. I was able to make a simple HTTP call and return and
display a string of data. Of course, the real world needs more
complicated data. I was reading about JSON to transferring objects and
figured I could use it.
1) now my first question/doubt is whether I'm using it right. From the
GWT docs reading it seemed like I should be sending a string of data
encoded as a JSON object/array and then process that at the client
side and display the information accordingly. So I did the following
to my server side class
import import com.google.gwt.json.client.*;
public class . {
public void method1()
{
retrieve data from backend.returns a list of objects
// to send data back to client //
JSONArray jsonArray = new JSONArray();
int index = 0;
while(iterator.hasNext())
{
String s1 = list.next().getValue();
String s2 = list.next().getAnotherValue();
JSONObject jsonObject = new JSONObject();
jsonObject.put(key1, JSONParser.parse(s1));
jsonObject.put(key2, JSONParser.parse(s2));
jsonArray.set(index++, jsonObject);
}
response.setContentType(text/xml);
response.setHeader(Cache-Control, no-cache);
response.getWriter().write(jsonArray.toString());
}
I see that this doesn't work and returns a 500 error back instead of
an expected response. Upon further investigation I saw that the code
kept failing right at the moment the JSONArray declaration is reached.
It compiles fine though.
My questions are
a) Is this a valid approach to how JSON is to be used within the GWT
toolkit and Java back end? If yes, what is wrong, if not what is the
correct solution to the problem?
b) On a different note, I was also reading about RPC and about the
serializable types that it would pass across and so on. I use XmlBeans
and figured I could just as well use the bean (or a collection of
beans) and pass it to the client using RPC calls where it would be
processed. Is that even possible?
Thanks
Suri

Re: Question about racing condition with refresh in linux.
Hi kozura,
That is almost exactly what i am doing:
public class Mypage {
Listbox list;
public Mypage() {
//generates panels..
setListBoxValues();
//generate restof panels, buttons etc.
}
public setListBoxValues() {
AsyncCallbackListString lboxCall = new
AsyncCallbackListString() {
public void onSuccess(ListString result) {
for (String item : result) {lbox.addItem(item);}
}
public void onFailure(Exception ex) {}
};
service.getValues(lboxCall);
}
This setup worked great on windows..but on linux i sometimes get the
entire GUI shown and sometimes only the panel with scrollbars without
any other GUI -buttons,lists etc. So I am kinda lost on why it is
happening.. Sometimes I have to hit the refresh button on the gwt
window to make the entire gui to show, but sometimes that doesn't do
the trick the first time but i had to do it several times to get
everything to show up... is this a bug?
On Oct 13, 12:28 pm, kozura [EMAIL PROTECTED] wrote:
Shaselai,
There should be no racing condition, the only thing I can guess is
that you're trying to use the result from the server call in your code
to initialize the page. The data from a server RPC call is highly
unlikely to be available a that time. The correct method is for the
asynchronous callback to fill in the previously created listbox, which
ensures that there is no race. For example:
public class MyPage extends Composite {
ListBox lbox;
public MyPage() {
lbox = new ListBox();
//add listbox to page
rpcservice.getListBoxItems(args, lboxCb);
...
}
AsyncCallbackListString lboxCb = new
AsyncCallbackListString() {
public void onSuccess(ListString result) {
lbox.clear();
for (String item : result) {lbox.addItem(item);}
}
public void onFailure(Exception ex) {}
};
}
Remember, GWT builds everything dynamically, so there is no real
refresh concept like you mention.

Re: HTML inside a text box
Hi Steve, Have you checked out the RichTextArea widget? You can see it in action in the Showcase sample application (link below). Showcase sample app: http://gwt.google.com/samples/Showcase/Showcase.html The RTA doesn't do auto-detection of things like hyperlinks where if I type something of the form http://... it will automatically change it to a hyperlink, but the RichTextToolbar implementation in the Showcase sample application does provide a Create Link button which allow the user to link text as they see fit.

Re: GWT implementation of java.text.*, Collator equivalent is missing!
On Tue, Oct 14, 2008 at 10:01 AM, JohnnyBGood [EMAIL PROTECTED] wrote: Google has done a great job when created internationalization support for GWT apps. Its i18n capabilities are however far from exhaustive. One of the features I'm missing most is a support of java.text.* JRE subpackage, more precisely it's java.text.Collator. I haven't found any possible solution of comparing strings in GWT, regarding locale- based rules (lexical Unicode based comparing used in String class of course doesn't do the job). Comparing (and sorting) strings with regard to international rules seem as being of essential importance to me, does anybody know anything about it's future (maybe planned) implementation in GWT? THX Jan. I don't know anything about upcoming support for Collator. My guess is that it's not on the radar. You may want to file an issue in the bug tracker. If you need something now, I suggest trying to port something from the Apache Harmony project. I have no idea how Collator is implemented so I don't know if it's even feasible to port but, in theory, you just need to borrow the code, remove bits that won't work with GWT, and add the result to your project. The Harmony project is already licensed under the Apache license, so it's perfectly compatible with GWT and closed-source products (of course, consult your lawyer for real legal advice--I'm just an internet wacko). There have been a number of posts to this forum about creating libraries for use with GWT so you should be able to get pretty far along if you decide to go this route, but feel free to ask again if you get really stuck. I'd guess that the hardest part of the plan will be getting the code into a translatable-and-still-useful state because Unicode-related stuff in Java usually involves compressed binary tables of data and that approach isn't really compatible with GWT. The ultimate GWT port of Collator is probably going to involve at least one generator, will nicely dovetail with the existing i18n support, and doesn't waste bandwidth or execution time in code that doesn't require Collator. You could probably get a lot of mileage out of a sub-optimal solution, though, so don't be afraid to jump in with both feet.

Re: Need help with using GWT on Linux
Hi Pete, The GWT distribution for Linux contains its own instance of a Mozilla installation (mozilla-1.7.12). You would need to use that Mozilla installation in order to get GWT hosted mode up and running. You can safely remove the mozilla-1.7.13 line unless it's available on your system, as well as the /usr/lib64/mozilla line as GWT currently doesn't work with 64-bit binaries. The export GWT_BROWSER and GWT_EXTERNAL_BROWSER environment variables are used to instruct GWT which browser to open up when going into web mode by hitting the Compile/Browse button in hosted mode. Let me know if any of the above info helps. If not, I'll try checking it out with one of the hosted mode experts to see if they know what's going wrong.

Re: GWT + JSON + Server-side code....... RPC ???
Well google can send serialable objects. So it does not have to be
json. It would be a whole new class of objects that you created.
google's json code itself is not serialable. You can however have two
liberaries for json and past the format from one to another.

Sorry, I forgot to say the it perfectly works in hosted mode. But when

If I whould be able to know that the compiler is complaining about and

Re: Your opinion sought: Jetty or Tomcat?
Since creating a usable server side configuration in the embedded servlet container is all but impossible for anything but the simplest projects, I think that the choice of embedded server is a non-issue. Since complicated configurations aren't really something you want to address in the embedded server, my vote would be for the simplest, fastest implementation that supports the simple case uses. So, if Jetty starts faster and is lighter weight, then great, use it. -jason On Oct 13, 2008, at 4:48 PM, Bruce Johnson wrote: Hi everyone, Hope you're enjoying 1.5.

Two of the areas we want to work on for 1.6 are some improvements to hosted mode startup time and a friendlier output directory structure (something that looks more .war-like). As part of this effort, we've all but decided to switch the hosted mode embedded HTTP server from Tomcat to Jetty. Would this break you? (And if so, how mad would you be if we did it anyway?)

Re: Your opinion sought: Jetty or Tomcat?
It already is! have a look at -noserver My project requires a full blown JEE container, not just a servlet engine, so neither tomcat nor jetty would be enough. I have been using -noserver since the beginning and it works great. If the embedded server doesn't fit your needs (no matter what that server ends up being) then it is no big deal to use whatever server does work for you. -jason On Oct 14, 2008, at 8:34 AM, jvanroekel wrote: We run Tomcat in production and on our desktops.

Re: Enter the Container
Ok, main concept is that there is real need to CREATE widgets not only by combining existed widgets. Example 1: I need create widgets from the hand created DOM Element complex (Diego case described here http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/78c45552015ea220) or from the existed node in html page (my case) It is live example. It's like some sort of template engine. I have very complex panel with element model mainly static with some slots where dynamic widgets should be attached. I don't want to write Kb of code to build this panel with Composite(wrapper) and static panels, labels, tables etc. It is static content. Nearest analogy - It's like servlet and jsp. I can write html tags to the output from the servlet (evil) or I can create a jsp where all static data will be contained in plain html and work only with the dynamic parts. It's the same case. How much elements from DOM are really dynamic (has listeners or could be manipulated from code etc?) in the real applications? 10%? 20%? As I understand this example not in the mainstream concept of gwt, but nevertheless... Example 2: I need to create widgets from strings. It is tables of course :) Data received from the server side should be displayed as table...biiig table. And I need to put external widgets there. Grid and FlexTable are not helpers in this case (yes, I know about gwt- incubator tables, but I write my own implementation ;). But I agree, this case is very specific. As I understand it is not API bloating, ti is just normal flexible API. Now gwt widget model is very monolithic and highly tied. I don't want to totally rewrite widget model like some gwt-libs do(ext-gwt etc), I'm satisfied with it in general, but in some details I am not. I want just to extend it. I understand developers care about users, but some users want more and don't like excessive care. Yesterday, I try to hack package visibility for setParent and create base Component something like Folke suggest, but moving forward I discover Widget.removeFromParent and final accord - if the parent is not HasWidgets widget throws runtime exception. Сheckmate. :( It is especially strange, because Composite doesn't implement HasWidgets but it used as parent for wrapped widget!!! What is going on? And about realization with Composite and/or Panel. I know that I can use them to achieve end, not all cases, but.. there is good russian proverb: it's like remove tonsils through a...hmmm...back, too much unnecessary work. As I understand setParent() method is package protected because of it is invisible(utility) part of the atomic attach/detach operations. But, attention, I understand It! I do can do the same right things that gwt developers do. I 'll be very careful with parent-child relations in YOUR widget model in MY application. I promise! :) With best regards, Dmitry. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

OK, so that partially answers the question, at least now I can see
that my overiden css elements are being ignored for the standard.css
ones.
So, question - does this mean that I have to rename mine and then use
the SetStyle method to get this working?

}
.gwt-StackPanelItem gwt-StackPanelItem-first{
}
.gwt-StackPanel .gwt-StackPanelItem {

RE: GWT and Firefox
I'm pretty sure that if you remove or comment out (with !-- comment -- since
this is xml) the following line in your .gwt.xml file, it will stop including
standard.css:
inherits name=com.google.gwt.user.theme.standard.Standard/
I'm not sure that this is really your problem though. Make sure your elements
have the class you want applied to them maybe?

So, question - does this mean that I have to rename mine and then use

It's very frustrating.
I suspect a number of things maybe causing the problem
a) My app is not picking up the css file from the Module xml file.
b) It could be because my app has mixed Upper and Lower case chars in
it BDFTReportManager
c) Something to do with a missing inherits flag in the module file,
mine is a very simple proof of concept app at this stage and has no
RPC stuff in it, so I can't see why
d) I've tried dynamically loading the css file in the HTML file with a
standard link flag
e) I'm using a StackedPanel and TabPanel and these are the 2 where the
standard css settigns are not working and they just default back to
the default set.
f) I've tried to ensure that i am using the SetStyle method to force
the code to use the right css setting ... no luck.
I am just totally baffled, and I'm pretty sure it'll be something
really simple we just need a GWT expert to shine the light on it

Re: Search API
Hey Max --
Unfortunately you cannot limit the Search API to a specific country's Google
search engine. However, you can limit the search to a language:
webSearch.setRestriction(GSearch.RESTRICT_EXTENDED_ARGS, { lr :lang_FR});
Hope that helps,
Ben

Re: GWT and Firefox
yea, I did that and it didnt change anything sadly, now it says it
using the
.gwt-StackPanel {
but it's just blank in firebug. I suspect it's just not loading my
css file.
I'll retire hurt for today and try again tomorrow, just frustrating
that this is so different between IE and FF
and tips overnight will be greatfully received. thanks Perelman

Re: Most efficient way to transfer larger amounts of data via RPC?
Ok - I'm going to work with the request builder for now and see how that goes. Really my only issue at this point is the slow RPC transfer. On the client side, the data is parsed into a structure upon receipt, consisting of several different kinds of HashMaps and ArrayLists of a few basic object types. I was able to do this in a single pass of the file and for a 100K configuration file, it's finishing in under a second on Firefox (longer in IE - but still fast). Once complete, subsequent queries of this structure are just a few ms. This is on a 5 year old laptop, so the client-side processing doesn't appear that it will be an issue. Thank you very much for the help and pointers! I'll let you know how it goes. -Matt --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: FF3 winxp on OOPHM rev 3747 branch fails with No GWT plugin found
On Tue, Oct 14, 2008 at 2:48 AM, gslender [EMAIL PROTECTED] wrote: Re the warning - loading both plugins fixes the warning. I don't get it anymore. Right, since Firefox thinks it has a plugin to match the embed tag, even though hosted.html will never use it because it finds the XPCOM plugin first. After when the app first loads into the browser, if I refresh it fails with some kind of index out of bounds exception. This happened before the 2nd plugin was installed, so its not a both plugin installed issue (just in case you were gonna think it was that). Every first load works fine, just the refreshes that fail - I'm not too concerned as obivously much of oophm is not complete and will continue to test releases from SVN every now and then. Can you reproduce this with the samples? Say, run Hello-shell then refresh the page? For me, it shows the old one disconnected and creates a new connection, as expected. Where do you get the out of bounds exception? If it is only with your application, can you provide any details about it? BTW - great work guys and can't wait for a Google Chrome/Webkit version !! That's gonna rock !! WebKit is already supported, so you can use most WebKit-derived browsers on MacOSX (Safari on Windows doesn't support the same plugin infrastructure). -- John A.

Rajeev / Alex - Can you summarize what the problem with RequestBuilder and RPC? I don't see an issue associated with the fix, and it would be good to use something more descriptive than it was broke. Here is the commit log: For IE7, we should be instantiating an XHR with the native XMLHttpRequest object. On IE6, try specifying which version you want first, then falling back to Microsoft.XMLHTTP. This seems to work around the do a POST when you asked for a GET bug on some IE6 installs.

[gwt-contrib] code review requested for 1.5, issues 2836, 2894, 2911 - various I18NSync issues
Please review this change for 1.5.3 which fixes a number of small issues.
The patch is larger than you might expect because it includes parts copied
from elsewhere (and then simplified) for choosing what characters to quote
and how to quote them, but at this point I felt it was safer to copy them
than to try and refactor the code to make it usable here. Tests were
corrected (previously the output could be nondeterministic in the case of
duplicated keys in the properties file, now it is deterministic which
required some changes to tests which only happened to work before) and new
tests added. The last part of the bulk is the updating the generated files
to match the output of I18NSync.
Toby, I would like you to look at the ClassLoader changes to I18NSync.java
-- you can ignore the rest if you like.
This was tested by running I18NSyncTest_ (which is not included in our test
suite) and then running I18NSuite which runs all the tests using the
generated code.

[gwt-contrib] Re: [gwt-team] Release Notes for review
We'd gotten a report that for some IEs, when you instantiate the XHR with new ActiveXObject(Microsoft.XMLHTTP), if you try to do a GET with that object, it does a POST. This patch fixed that problem by using a different string (or just the native XMLlHttpRequest object). I was able to reproduce it for a while, but the underlying bug also seems to have been fixed by an update on my Windows install. This was a problem with anything that involved HTTPRequest, not just rpc.

[gwt-contrib] redirect results
1st issue
I am interested in looking at the code that handles errors coming back
from an XmlHttpRequest. After checkout, where would I look for this?
Basically, in seam using AJAX, if the response to an XmlHttpRequest is
a redirect message, the entire page redirects. I kinda wanted the
same thing in GWT so I could reuse an already written ServletFilter
which redirects for security purposes(but alas doesn't work). I tend
to think this could be fixed OR at the very least could result in a
RedirectUnhandledException rather than a standard InvocationException.
2nd issue
Also, I would move my filter code down into a common processCallImpl
method where I would like to throw Exceptions that GWT
RemoteServiceServlet would translate but this is not possible as the
code was moved into RPC static methods. I really want a method in
RemoteServiceServlet like so
processCallImpl(Method m, Object[] params) {
return m.invoke(params);
}
Then, I can override that and use it as a filter(and my method would
call super.processCallImpl.
thanks,
Dean

Log:
Fix RPC quoting and add more thorough tests for both client-server and
server-client.
All Unicode characters can now be sent in both directions via RPC on all
supported browsers, though some browsers will still have some issues with a
few characters. Problem areas to consider if you run into trouble are:
- combining diacritical marks being combined with other characters
- unpaired or incorrectly paired surrogates
- undefined characters, such as U+
Note that we have special-case Android WebKit due to a bug in its UTF8
handling -- issue 2980 has been created to track removing this when the
problem is resolved.

Ok, here is a revised patch, which adds quoting for all non-ASCII characters on Android. Given the way this is structured, this check is only performed once when ClientSerializationStreamWriter is initialized, so I think it is acceptable overhead. While it isn't clear how these characters would be entered (they could come from the server), if they aren't used there is no cost and it guarantees that they will be properly handled.

Alright, taking a look! The code looks good (one typographical nit), but I'm pretty sure you should change the comments in the tests that reference local files on your machine. Also, all the test files should have copyright notices (don't they?), but it looks like you took some of them out. Let me know if I'm confused about the copyright notices.

Tests were corrected (previously the output could be nondeterministic in the case of duplicated keys in the properties file, now it is deterministic which required some changes to tests which only happened to work before) and new tests added.

[gwt-contrib] Re: RR: SOYC Correlation work
Kathrin and I reviewed this together. In general, this solves an important use case, so let's move forward on it aside from minor issues. The following use cases are the ones we could think of: - Seeing what amount of output code (and in fact the actual code if you want) corresponds to what input Java code, at several granularities: field, method, class, file. This information is obtained by the current patch. - Browsing call graphs to see why a particular method (field, type, ...) is included or why it is considered reachable before any runAsync occurs even though the programmer intended otherwise. This is not yet implemented but would be simple to add a new correlate for why a node is kept alive. Normal Pruner runs would not fill this in, probably, for efficiency, but it should be enough to run the Pruner once, after all optimization is done, in a mode that causes the reasons to be recorded. - Helping trace a method all the way through compilation. This has too many open questions to really address right now. - As a helper for the runAsync implementation. I think the general structure is fine. I will give it a try and we can follow up in further iterations. There is one possibly important general concern that you should look at right now. SourceInfo is compared by value, but there can be multiple source infos for the same file, line number, etc. that are nonetheless not the same object. For example, several of the getLiteralFoo methods in JProgram will generate SourceInfos that have exactly the same fields but are separate objects. The reason this might matter is that SourceInfo also has some fields that use SortedSets of SourceInfo. If you add as ancestors two SourceInfos that are not reference equal but that have all their fields the same, then only one will actually be added as an ancestor. Since individual SourceInfo objects carry correlates, this could seemingly lead to problems. One way to fix things would be to add a unique id to all created source infos. Another possible solution would be to use a LinkedHashSet in the implementation, and then sort when the report would be made. I'm not sure, it just looked like a possible issue you might want to think about. Other general issues can wait. For example, what does parent/child mean? I originally thought that it meant that the child is a later version of the parent, after some optimization. However, that isn't the case on further thought. There are many places where a node is considered a child of some other node that it is related to in another way. For example, methods are considered children of their surrounding types. For runAsync in particular, it might be necessary to have fewer parent-child links and to do more with explicit correlates. I'll look into that as soon as possible. Finally, finding correlates is unfortunately slow, because the whole chain of parents and ancestors is chased every time a request is made. At some point it might help to do one of: - Eagerly copy down correlations, instead of waiting for a call to getCorrelates. Possibly even don't keep the parent links with this approach. - Disallow adding ancestors after some point, like with a builder pattern. This might help keep caches from being invalidated too frequently. smaller but real concerns: One of the two versions of BuildTypeMap.emakeSourceInfo does not check enclosing for null, but it can be null. Correlation.equals() and .hashCode() should account for the underlying AST node if present. Otherwise, there will be confusion if different objects have the same associated ident. It seems like that can happen, for example due to overloading. smaller concerns you might or might not want to do anything about right now: SourceInfo.compareTo assumes fileName is not null. Is that reliable, or would it be better to use compareTwo? If it needs to not be null it would be nice to have an assert in the constructor. SortedSet.getRoots: it looks valuable to use the cache even if there is a parent and no ancestors. Otherwise, the compiler can end up repeatedly chasing the same chain of parents. So, it looks better to consistently use and update the cache, except possibly in the case where a node is itself a root. To simply all this, it might help to break out a separate computeRoots() methods that does not cache. SourceInfo.additionalAncestors could be null in the common case (isn't it?) that there are no ancestors. Currently it always holds a TreeSet, even when it's empty. Normally I'd hate such a micro-optimization, but there are likely to be a lot of SourceInfos floating around. SourceInfo.hashCode: Adding the individual hashes is fine but it's better to scramble them up. Josh Bloch recommends a pattern like the following: int result = 17; result = 37 * result + hash1; result = 37 * result + hash2; // etc return result;

And this is the native code that somehow causes the
IndexOutOfBoundsException ??
public final native void setStyleAttribute(String attr, Object value) /
*-{
this.setStyle(attr, value);
}-*/;
Go figure?
WebKit is already supported, so you can use most WebKit-derived browsers on
MacOSX (Safari on Windows doesn't support the same plugin infrastructure).

Ok, here is a revised patch, which adds quoting for all non-ASCII characters
on Android. Given the way this is structured, this check is only performed
once when ClientSerializationStreamWriter is initialized, so I think it is
acceptable overhead. While it isn't clear how these characters would be
entered (they could come from the server), if they aren't used there is no
cost and it guarantees that they will be properly handled.
When the UTF8 encoding issue is fixed, we can revisit how we want to handle
the Android version check.

Likewise for other javadocs in the file. Since JsArray is a JavaScriptObject subclass, you would get an exception immediately if a primitive were returned. But, if it were a subclass of Object that wasn't an Array, you won't get an exception until you tried to pull out a member of the array. I really just wanted to call attention to this reason for a JSE, because it isn't a declared exception and it is up to the author to make sure the message types are in sync - there is no magical translation between types going on.

I don't really have time right now to dig into it nor really a way to
reproduce it, but from the stack trace you posted it might be an ExtJS issue
or something triggerred by something they are doing.
XElement.setStyleAttribute is calling this.setStyle, which is presumably
some JS method on the GXT.Ext.Element JS class, but I don't know enought
about ExtGWT to track it down further. You might try setting a breakpoint
on El.setStyleAttribute, then setting breakpoints on
OophmSessionHandler.{getproperty,setProperty,invoke} to see what the native
code is calling that is causing the problem.
You could also disable ModuleSpace.scrubStackTrace (just add return at the
beginning or comment out the contents) so it will leave hosted mode frames
in the stack trace.

[gwt-contrib] Patch for TreeMap serialization
Hi all,
I have attached a patch for TreeMap Serialization. The patch has been
reviewed by John Tamplin. Most of the code is similar to the way we do
serialization/deserialization for HashMap. The deserialization is done
element by element and the tree is being built incrementally. John pointed
out that this approach is fine for now, since the TreeMap implementation
currently does not use the SortedMap constructor.
There is just one drawback to this code going in 1_5_3. To get Stob to
generate serializers for the key and value types, based on Lex's suggestion,
I created two private variables that are not being used anywhere. Since my
tests run correctly, either the compiler does not optimize away these two
variables or Stob is looking at the code before these are optimized away? In
both situations, there seem to be optimization opportunities. Moreover, in
the former case, anyone using TreeMap would suffer an increase in codesize
regardless of whether they use it for serialization or not. Am I missing
something here?
Thoughts about whether this code should go in 1_5_3 or not?
Regards,
Amit

[gwt-contrib] Re: RR:JS collections
I realize I may be jumping in late to this discussion, but Bruce just introduced me to this fine contributors group. At a talk during the Google I/O conference, I mentioned the benefit of using the GWT FastStringMap implementation over the HashMap implementation and I decided to re-run my analysis for 1.5 to see if the 1.5 compiler was smart enough to pick a faster implementation and unfortunately that does not appear to be the case. I hope I'm not hijacking Emily's thread, but I just thought some of you would find my (basic) data interesting for HashMap vs. FastStringMap. I posted my results up on my company development blog if you don't mind me not copy-and-pasting it all here: http://development.lombardi.com/?p=95 --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
