Re: Best image preloading practice?
You are thinking of loading 20MB of images into the DHTML DOM of you application Am I? Does the DOM keep them there even when not displayed? These images certainly wouldnt be displayed all at once. 1 or 2 at a time at most. I'm not absolutely sure, but I think if you load an image it is basically attached to a document, whether the browser caches it or not, and whether it is currently visible of not. You don't control the browser cache, I mean I don't think you can tell it to conveniently download all your images and store them neatly on disk until you need to display them for example. ah, pig. I thought that was exactly that prefetch was doing -sigh- I thought it loaded it to ram first, then the browser keeps a copy in its cache for reloading if needed. -sigh- That does change things indeed then. AFAIK the prefetch creates an IMG element but its not attached to the DOM. - Litty On Fri, Feb 6, 2009 at 1:03 PM, darkflame darkfl...@gmail.com wrote: You are thinking of loading 20MB of images into the DHTML DOM of you application Am I?

Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? yeah, the staggered download is basically the idea of the maze - each time you move to next location you've only got one locations worth of images to fetch. Or if it worked fast enough you could fetch all the required images for the adjoining locations so they would be ready to go instantly. It depends entirely on no of image bytes per location. Yes, I looks like I'll be switching to a as-you-go-along-it-loads-the- next-rooms approach. Allthough... Point is doing it this way old images are thrown away and can be garbage collected as you go, so you are not accumulating images in memory. It's stable. (assuming I'm right about the how this works of course). ...I'm not sure there will be much that can be chucked away in this game. My engine is able to remove items easily enough, but for this game items from the start of the game are still usefull at the end, so theres only a few case's when images can be removed never to be recalled. . The point of the composite image strip is to fetch several images in one request since they come in a single binary file. Yes, I understand the point of them, and I think image bundles are a great idea. (In fact, online in general, theres probably a lot of wasted bandwidth used on little UI elements on webpages..like 5kb gifs etc) In this specific case though they arnt approperate. Not unless I got the server to dynamically splice the images together and the client to cut them up. But thats beyond the scope of the projects timeframe. This is exactly what the GWT ImageBundle does (and what has been best practice in web design for years). Annoyingly for you GWT only does this once per module because Bruce says they can't think of a single use case for needing separate ImageBundles! My bet is that if you just start loading all the images as you are suggesting, you will have to attach them to the DOM somewhere, so ultimately what you will be doing is building the entire game at the same time as the player is trying to play the first locations. So my betting is three to one on a) whilst this build is going on the game play will be badly affected at precisely the time you least want it to, and b) once you've loaded it all it will run like a dog anyway. Yes, I think your right there. But I think cutting up 30MB of images client side might actualy raise the required specs of the game :P I may well be wrong, but if I'm not, and you looked at the maze idea as plan B, then using image strips a la ImageBundle will make the game run much faster and smoother, so the effort might well be critical in the end. This is after all the heart of your technical challenge. This has been done so many times I expect you will find some javascript code that cuts them up (or maybe CSS stuff) to crib from somewhere and some server side tools to pack the image strips as well. I may have miss-understoof how image bundles

Re: Script error in IE 7 in web mode
Arend, Thanks for the reply. I've been able to pinpoint the place where the problem occurs and it is indeed in a class where I parse the XML reply coming back from the server. It was working fine previously in all browsers. The difference is that the XML is larger now. Maybe Internet Explorer has a limit on the size XML documents that it can handle. I will investigate further and post my findings. Danny On 5 feb, 16:45, Arend van der Veen arend.vanderv...@gmail.com wrote: Hi Danny, I had a similar problem when I was parsing an XML document.

Re: HorizontalSplitPanel issues in Firefox 3
Hello, anyone? On 4 fév, 16:15, vince vincent.kir...@gmail.com wrote: Hi, I face an annoying issue in Firefox 3.0.6 (that doesn't occur in IE7). My application uses aHorizontalSplitPanelas main panel. The left side contain a StackPanel. There are 2 panels composing the stack panel. One displays a tree, the other one is a small search panel displayin a possible result list. When the user clicks on either a tree node or a row in the results list, the application retrieves a PDF file and displays it in the righ side of theHorizontalSplitPanelthrough a Frame. The URL of the frame is set by calling a simple (as in non-GWT RPC) servlet. Now the issue is that as soon as the PDF is displayed in the right part (the default PDF reader plugin is used, in this case it's Adobe Reader 9), the splitter acts weird when I try to drag it: * If I drag to the left, it resizes OK and everything's fine. * If I keep my finger on the left mouse button and try to drag to the right, then it becomes all weird. The splitter won't move to the right! On the other hand, it still moves to the the left --even if I release the mouse button! To make this behaviour stop, I have to click a single time on the splitter. But I still can't move it to the right if I try to do it normally. Instead, the only way to make it move to the right is to click the splitter, move the mouse cursor to the top of the current Firefox tab, and then go to the right. Note that in this case too I can release the mouse button and the splitter will keep moving, and again I have to click on the slpitter once to make it stop moving. I don't get this behaviour in IE7. I get it in Firefox 3.0.6 and also had it in 3.0.5. Anyone ever got this? Is there a possible fix? I just hope it's not a PDF plugin issue...

Re: RPC call efficiency
Hi Rick, In my experience RPC is very efficient - I have a 100 or so objects serialising over the wire in less than 50ms, with simpler structures taking even less time. Something that returns just a long should complete in no time at all. Have you tried adding some timing logic to the server code that produces that long value? What timings do you get if you just return a hard long value? Using a HTTP proxy like Charles (http://www.charlesproxy.com/) will shed some light on the size of the RPC calls being made and will provide some more precise timings. Good luck, Chris.

Re: Best image preloading practice?
I use Firebug as well as the inbuilt tools of Chrome quite a lot. I will check out Fiddler2 though, thanks for the recomendation :) The thumbnails could be prefetched without problem, and even image bundled most probably. However, the bigger images they link too I wouldnt want to load on the fly because some of these could be VERY big, and the loading too noticeable to be used as a game. Specificaly if you drag the magnifying glass over items it loads a bigger image version of them in a clipped box, if the bigger image isnt already loaded, this dosnt work very well. (actualy, it just looks like the magnifying glass isnt working at all). However, I'll check out fiddler and try to use it with the maze- techique for preloading stuff to optimise. On Feb 5, 10:28 pm, Martin Gorostegui martin.goroste...@gmail.com wrote: Hi darkflame, I think the best way of (pre)loading images depends on the kind of app you have. I visited the url you shared with us and run a Fiddler2http://www.fiddler2.com/session through it to discover that around 100 requests are fired to get icons, textures, buttons, gradient bars, etc which could be loaded all in one request using an ImageBundle and doing that will surely improve the loading time of the app. Then you have like another 100 requests that fetch a combination of thumbnails and bigger images with good quality (ranging from 10kb to 1 meg aprox). For what I saw many of these images are displayed only when the user clicks on the inventory bag (thumbnails) and then when a thumbnail is selected the bigger image is displayed so I think you could also use Image.prefetch to, for example, get all the thumbnails when the initial screen is loadad (so that when a user clicks on the bag they appear quickly) and also prefetch the bigger images when the user clicks on the bag so that when a thumbnail is clicked the big image appears quickly also... or maybe you could just load a big image when it is needed! I think these are the kind of decission you can only make by having the app running and using tools like Fiddler2 or Firebug to see loading times, number of requests, use of browser cache, etc. I hope this helps, Martin On Thu, Feb 5, 2009 at 5:24 PM, gregor greg.power...@googlemail.com wrote: Ah, this sounds quite usefull to hide the loading, allthough I'll have to read up.

I.e. you've got a document of 20MB loaded which it must manipulate. I may be wrong, you'd need to investigate to be sure.

Re: Why can't I use GWT Theme support with a Gadget?
I just wrote the FAQ item yesterday, so I haven't a chance to explore a lot of different options. If you want to go the absolute path way, you could also use an external script that does some text processing (perl, python, sed) to substitute variables into your css from before deploying it. Another way to solve this is to use the Stylesheet Injector (currently in the incubator) and processing the stylesheet text and doing some substitution with _IG_GetCachedUrl(). I would appreciate feedback on these or other options for making stylesheets work better with gadgets. This is a place where GWT could add a lot of value. On Fri, Feb 6, 2009 at 1:51 AM, chip ginga.gadg...@gmail.com wrote: ;) In the FAQ it explains how GWT references a CSS file with relative image paths. When the GWT app in question is a gadget it is hosted through a proxy by the gadget container and all the relative image paths break. There are two issues here. 1) It would be nice if there was a way to indicate where the final home of the images would be so that the GWT compiler could build absolute paths 2) It would be even better if the reference to the images were wrapped in calls to _IG_GetCachedUrl() - I'm not sure if this is possible with an external CSS file, but I know it can be done when the CSS is inline. Any info on if these issues are being addressed? Any thoughts on solutions/hacks in the meantime?

Re: FlowPanel
That's the way FlowPanel works. It's just a div tag. If you want them to stay on the same row you have two options a) use CSS to position them on the same row, or b) use HorizontalPanel which uses tables. -- Arthur Kalmenson On Thu, Feb 5, 2009 at 9:57 AM, TIGR www.dzgr...@gmail.com wrote: I have FlowPanel with some widgets, but I need some different behaviour when adding new one.

Re: Deploying GWT application (WAR)
It's exactly what i try to use. I use the gwt-dev-linux.jar to get the catalina.tomcat package, and the server runs fine. But i don't success to deploy my applciation. I built my war as described in the faq (pretty sure it's ok), moved it to the webapps folder (the one which is gave by the gwt installation, i would like to use this tomcat install). When i launch to localhost:, it says me to enter the module name/ html file, so i enter the name of the war without the .war but it says me no module named ...) So i'll investigate a bit more on this and will let you know if i success or not. Is there any other way to do it easily ?

Re: ScrollPanel maxWidth or maxHeight?
Is there a real browser-event or should i just call a check procedure whenever i add elements? The latter, no browser event available AFAIK. I have looked in vain for a general method to get ScrollPanels to resize and generally behave by themselves. I think the reason is that individual divs/table cells etc do not generate events when their size changes. ScrollPanel is basically a div with an overflow setting. I have supposed this is because there can be hundreds if not thousands of boxes on a page, so if they all emitted an event every time they changed their width/heights the browser's event queue would be brought to its knees.

Announcing GWT 1.6 Milestone 1
Greetings GWT developers, The GWT team is happy to announce the availability of 1.6 Milestone 1! Binary distributions are available for download directly from GWT's Google Code project. http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=1.6.0 As always, milestone builds like this are use-at-your-own-risk. There are known bugs, and it definitely isn't ready for production use. Please expect some trial and error getting everything to work. The javadoc that comes bundled with the distribution should be up-to-date, but the online Developer Guide (http://code.google.com/docreader/#p=google-web-toolkit-doc-1-6) is still very much a work in progress. We will be updating it over the next several weeks. In lieu of an up-to-date Developer Guide and release notes, below are the major highlights relative to GWT 1.5.3. *** New Project Structure in GWT 1.6 *** One of the biggest changes to GWT 1.6 is a new project structure. The old output format has been replaced by the standard Java web app expanded war format, and the actual directory name does default to /war. Note that the war directory is not only for compiler output; it is also intended to contain handwritten static resources that you want to be included in your webapp alongside GWT modules (that is, things you'd want to version control). Please also note that the GWTShell and GWTCompiler tools will maintain their legacy behavior, but they have been deprecated in favor of new HostedMode and Compiler tools which use the new war output. When 1.6 is officially released, we will be encouraging existing projects to update to the new directory format and to use the new tools to take advantage of new features and for compatibility with future GWT releases. The sample projects provided in the GWT distribution provide an example of correct new project configurations. For more details on the specifics of the new project format, please see GWT 1.6 WAR design document ( http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6). A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep such handwritten static files separate from those produced by the GWT compiler, the latter will be placed into module-specific subdirectories. Any page that wishes to include a GWT module can do so via a script tag by referencing the GWT-produced module.nocache.js script within that module's subdirectory. As of 1.6, we'll be recommending that only module-specific resources used directly by GWT code, such as image files needed by widgets, should remain on the public path. See the included Showcase sample for some examples of this distinction. - When you do need to load resources from a module's public path, always construct an absolute URL by prepending GWT.getModuleBaseURL(). For example, 'GWT.getModuleBaseURL() + dir/file.ext'. This advice has not changed, but in the past it was easy to be sloppy with this, because the host page and GWT module typically lived in the same directory, so using a relative URL would usually do the right thing. Now that GWT modules live in a subdirectory, you must reference public resources through GWT.getModuleBaseURL(). *** Hosted Mode Enhancements *** Although the legacy GWTShell still uses an embedded Tomcat server, the new HostedMode runs Jetty instead. There is also a new Restart Server button on the main hosted mode window. Clicking this button restarts the internal Jetty server, which allows Java code changes to take effect on the server without having to completely exit and restart hosted mode. This is useful when making code changes to RPC servlets, or when serializable RPC types are modified and the server and client are out of sync. *** New EventHandler System *** Event handlers have been added to replace the old event listeners used by Widgets, History, and various other classes. The new system has a few differences from the old system: - EventHandler methods always take a single parameter: the GwtEvent that the Widget fired. For example, ClickHandler has a single method onClick(ClickEvent). - Each GwtEvent contains accessors relevant to the event, such as the key that was pressed on KeyEvents. Native events provide access to the underlying native event

Re: ScrollPanel maxWidth or maxHeight?
Haven't found one either. But checking height while adding elements is ok - have it almoust working already.

So, while panel shows the desired behaviour while adding elements, it remains big when elements are removed. I've already tried: scrollPanel.setWidth(); scrollPanel.setWidth(null); but no luck. I've also tried to set the style-attribute directly with DOM.setStyleAttribute(scrollPanel.getElement(), width, ); but no luck either. Sadly, i haven't found a removeStyleAttribute-method. Any ideas?

Re: Best image preloading practice?
@Litty: yes, I think you are right, my ignorance. Image.prefetch() will causes the image to be loaded into browser cache. You then use the same URL to instantiate an Image object later in code, and hopefully the image binary will be already downloaded. This old Mozzilla doc describes the process: http://devedge-temp.mozilla.org/viewsource/2003/link-prefetching/index_en.html The doc suggests the behavior darkflame described in OP, namely, browser is busy downloading all the prefetches it finds in the page. @darkflame: b) If I do have to load, say, upto 10 images that have to be seperate, is it better to just loop over a list of them prefetching and leave it upto the browseror should I put a timer and trigger a load every, say, 5 seconds ? (or dosnt it make much difference). My reading of the Mozzilla doc is that the browser will notice all the prefetch tags when it loads the page, and it will then get busy downloading them. So I have doubts whether where you put the Image.prefetch(url) in execution logic makes any difference, i.e. you do not have fine tune programmatic control over prefetch so you can't code to prefetch first 10, then later trigger prefetching next 10. For example the Mozzilla doc states The link tag has to be inside the head tag to make prefetching work etc. On Feb 6, 9:14 am, Litty Preeth preeth.h...@gmail.com wrote: You are thinking of loading 20MB of images into the DHTML DOM of you application Am I?

You don't control the browser cache, I mean I don't think you can tell it to conveniently download all your images and store them neatly on disk until you need to display them for example. ah, pig.

Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? yeah, the staggered download is basically the idea of the maze - each time you move to next location you've only got one locations worth of images to fetch. Or if it worked fast enough you could fetch all the required images for the adjoining locations so they would be ready to go instantly. It depends entirely on no of image bytes per location. Yes, I looks like I'll be switching to a as-you-go-along-it-loads-the- next-rooms approach. Allthough... Point is doing it this way old images are thrown away and can be garbage collected as you go, so you are not accumulating images in memory. It's stable. (assuming I'm right about the how this works of course). ...I'm not sure there will be much that can be chucked away in this game. My engine is able to remove items easily enough, but for this game items from the start of the game are still usefull at the end, so theres only a few case's when images can be removed never to be recalled. . The point of the composite image strip is to fetch several images in one request since they come in a single binary file. Yes, I understand the point of them, and I think image bundles are a great idea. (In fact, online in general, theres probably a lot of wasted bandwidth used on little UI elements on webpages..like 5kb gifs etc) In this specific case though they arnt approperate.

Re: RPC call efficiency
Just curious, what happens if you return a string, or an int rather than a long? longs are emulated in GWT and have been pegged as being a bit slow, but 1s sure seems like an awful lot. The other thing to do is pull up FireBug (Firefox), or WebInspector (WebKit nightly builds) and check the latency of the RPC call.

I looked at the recent additions to the Wiki that you pointed me to, and I still maintain the accuracy of my characterization but... 1) We ARE using Ext-GWT and we are glad we are using it. Documentation is a serious complaint but we're happy otherwise. It's just our biggest beef and people considering using GXT need to be aware of it, which was my point. 2) ExtJS is VERY responsive to bugs and questions, and the forums are very helpful. Not a substitute for documentation, but they dull the pain considerably. 3) I'm ecstatically happy to see that a book is coming out. I'm going to preorder copies for all my colleagues. This could eliminate the entire complaint if the book is decent. 4) I'm quite happy that work is being done on the Wiki. But the fact remains, that not much is there yet. As far as I can tell, the GXT MVC architecture (which IMHO is pretty darn good) is largely undocumented. One sentence descriptions often in the Javadocs even.

It'd be more accurate to say that the documentation is NON-EXISTENT and this is a SERIOUS SERIOUS issue you must consider before choosing it.

However... - Reported bugs tend to get fixed VERY quickly and if you are licensed, you can pick up the fix from the SVN as soon as they are fixed. - Ext-GWT has what I consider to be a rather nice MVC architecture built into it. It really goes well beyond, say, Swing's MVC because it not only de-couples Ms, Vcs and Cs, but decouples data-models, data loaders, etc. The MVC architecture has some problems with its generic implementation, but it's pretty good overall. - We think the components look nice, but then... we pretty much have customized everything.

Re: Calling of business method from Client
Hi Arul, Check out: http://code.google.com/p/google-web-toolkit-incubator/wiki/TreeTable Personally I find tree tables sometimes look confusing, especially if there are significant differences in the structure and/or size of the nodes, but a lot of people like them. They are also complicated widgets. I would consider as an alternative breaking up the structure into three widgets, for example: 1. A list of Accounts (Acc No) to pick from left side (a HorizontalPanel basically). 2. A standard Tree widget representing Account Name nodes at top level with the rules and tests nested underneath located top right 3. A leaf data panel to show details of a particular test or rule selected from the Tree, located bottom right. You could use HorizontalSplitPanel and VerticalSplitPanel to divide up the display giving much more flexibility to the user's view of the data, and I think you may find it looks a lot better and is easier to use. There are other alternatives involving DisclosurePanels etc. This approach may not only be easier for the user, but you may find it a lot easier to code as well. regards gregor On Feb 6, 3:48 pm, Arul arulmanikandan.sriniva...@gmail.com wrote: Hi Gregor, I some how managed GWT component as replacement of my presentation layer. currenlty my application will be displaying like tree structure as menu in the left hand and selecting each link its content is diplayed in right side in grid with rows and columns.

Well your existing JSPs are running server side as servlets whereas your GWT code is running as javascript client side, so whereas your JSPs have automatic access to httpsession your GWT client code obviously does not. I think you might have to make a preparatory RPC call to get the necessary parameters from the user's session before you construct the URL.

Google API Libraries for GWT: New binaries uploaded
Another round of updates is ready for the Google API Libraries for Google Web Toolkit (GWT). As just announced on the GWT blog, this update brings bug fixes and new features to three of the existing libraries. - The Google Visualization API Library for GWT moves from a release candidate to a public release with a few bug fixes. - The Gadgets API Library for GWT now supports GadgetAds , gadget based internationalization and an important bug fix for Windows developers using GWT hosted mode. - The Google Maps API Library for GWT now includes support for the GAdsManager and reverse geocoding support. We are also announcing a major update as a release candidate. The Gears API Library for GWT version 1.2.0 supports the Gears 0.4 feature set, which includes Geolocation, HTTP Request, Desktop and Blob. This release is exciting to me not just for the new features that have been added, but also for the number of new contributors to the libraries from the open source community. Special thanks to Mark Renouf for contributing Gears 0.4 support, and all those that filed issues and contributed patches. You can find the new libraries ready for download on Google Code. http://code.google.com/p/gwt-google-apis -- Eric Z.

Re: ScrollPanel maxWidth or maxHeight?
Oh right... I think you've got to make sure that the whatever the ScrollPanel contains has actually reduced in size already - if it hasn't the ScrollPanel will refuse to cooperate (i.e. it won't squash it's contents by itself). Then you need to reset it to 1px more than the height/width of its contents (1px is fine if contents is now 0) in order to get rid of the scroll bars (0px etc is ignored as I recall). It won't do that by itself. After that you'll have to try things out - I've always reset ScrollPanel's to a specific height after this procedure, so I don't know how to release it from the 1px instruction without specifying another. I think I would use debugger to find out exact style properties of ScrollPanel whilst it's in growing mode to start with, and attempt to replicate that. If it has nothing in height/width you may have a problem because, as you say, you may not be allowed to actually remove a style attribute once it's there, only modify it, in which case the ScrollPanel may stubbornly refuse to cooperate. You might be forced to attempt a detach of the items widget, replace ScollPanel with a new one, and reattach the items widget to it, or some such... or you might consider another way to do this altogether - ScrollPanel's can be tiresome, uncooperative widgets at times ;-) On Feb 6, 3:46 pm, Davsket g.ave...@gmail.com wrote: well, at least replace it..

Well, almoust - the problem is that when height or width properties are set once, you can't take it back. So, while panel shows the desired behaviour while adding elements, it remains big when elements are removed. I've already tried: scrollPanel.setWidth(); scrollPanel.setWidth(null); but no luck. I've also tried to set the style-attribute directly with DOM.setStyleAttribute(scrollPanel.getElement(), width, ); but no luck either. Sadly, i haven't found a removeStyleAttribute-method. Any ideas?

The latter, no browser event available AFAIK. I have looked in vain for a general method to get ScrollPanels to resize and generally behave by themselves. I think the reason is that individual divs/table cells etc do not generate events when their size changes. ScrollPanel is basically a div with an overflow setting. I have supposed this is because there can be hundreds if not thousands of boxes on a page, so if they all emitted an event every time they changed their width/heights the browser's event queue would be brought to its knees.

If what you mean is that you want a panel to start at a minimum size, then grow as things are added to it, but then to stop growing and go into scroll mode at a certain point, exactly what i meant. I do not think that is realistically possible since there is no event you can listen for that would tell you when the panel had grown to a given height. You can listen for the browser window changing, but not for an individual panel. I suppose one approach might be to set up a timer to check the current height at intervals and take appropriate action when it hit the limit, but this sounds very inefficient. Indeed it does. I kind of hoped somebody will have a genious idea about it ;-) Thank you for your input anyway. regards gregor On Feb 5, 9:29 am, alex.d alex.dukhov...@googlemail.com wrote: Hi folks, I'm trying to impelement a scrollpanel that becomes bigger (height) to the certain size (maxHeight) when populating it with data.

Overlay invisible in Web mode
Hello,
I'm new with GWT and GWT-Maps. I need to plot polylines over a Map
widget. My problem is that the polyline only shows up in Hosted mode.
When running in Web mode, I can't see it.
More detailed, there's an addRoutes() function I wrote to plot the
polylines:
private void addRoutes() {
boolean loadOK;
PolyStyleOptions pso =
PolyStyleOptions.newInstance(overlayColor,
weight, opacity);
DataLoader loader = new DataLoader();
loadOK = loader.LoadSegments(map, pso);
if(! loadOK)
Window.alert(asyncGet() failed.);
}
The LoadSegments() method of the DataLoader class tries to access
a segments.txt file, located in the module's root folder. That file
contains a list of GPS coordinates, defining the polylines.
private static final String segmentsInputPath = segments.txt;
@SuppressWarnings(deprecation)
public boolean LoadSegments(MapWidget m, PolyStyleOptions options) {
boolean result =
HTTPRequest.asyncGet(GWT.getModuleBaseURL() + segmentsInputPath,
new MapSegmentPlotter(m, options) );
return result;
}
Finally, the MapSegmentPlotter class implements the
ResponseTextHandler interface, by overriding onCompletion(String
responseText) to draw the polylines. I don't give its code here - but
I assume that it does the job - since the polylines show up in Hosted
Mode. However, no trace of them in Web mode. Where do I go wrong ?

Re: Overlay invisible in Web mode
I wouldn't assume that because everything worked fine in hosted mode
that web mode will work perfectly. There can be hiccups every now and
then!
You didn't say which OS/browser you were running, but one of the first
things to try is to run web mode under firefox/firebug and see if
there are some exceptions that might be short-circuiting your code.
There is a problem in the demo showing and hiding Polygons that I've
never been able to get to the bottom of, but that problem occurs in
both hosted and web mode.

Servlets and web.xml
Hi to all,
I'm under linux and I follow this tutorial
http://jeff.ourexchange.net/2008/03/01/deploying-gwt-applications-with-jetty/.
I have a simple gwt application that browses for a file and upload it
using a servlet (class FileServlet extends HttpServlet).
In hosted mode (with tomcat) with the hosted browser of gwt, all works
as expected, my servlet runs fine.
I try to deploy application to a Jetty embedded server and i get a
HTTP ERROR: 503 SERVICE_UNAVAILABLE if i enable my servlet in web.xml
(under WEB-INF). Also when i run the Jetty server (in console), i get
two exceptions like Failed startup of context
org.mortbay.jetty.webapp.webappcont...@1b9ce4b{/com.tergwt.Main,file:/
home/jon/GWTDeploy/webapps/com.tergwt.Main/}
java.lang.NullPointerException
I don't see the form of the upload.
If i disable the servlet declaration in the xml file, the server runs
without exceptions but it doesnt upload and i get h2HTTP ERROR:
404/h2preNOT_FOUND/prepRequestURI=/com.tergwt.Main//
FileServlet/p if i try...
So i guess it has something to do with the web.xml file.
Unfortunately, i don't success with it.
Here is the content of my web.xml file without the web-app marks.
servlet
servlet-namefileServlet/servlet-name
servlet-classcom.tergwt.server.FileServlet/servlet-class
/servlet
servlet-mapping
servlet-namefileServlet/servlet-name
url-pattern/files/*/url-pattern
/servlet-mapping
I don't know what else i can do to fix this problem as i'm not an
expert with these things.
My main.java contains the upload form and it uses the FileServlet to
make the doPost().
Here is the full tree of my webapp deployed folder with the embed
Jetty server : http://filebin.ca/cjgvj/tree.txt.
Thanks in advance.
Best regards.
Jonathan

Re: Embedding a JavaScript-based widget in GWT?
Hi Adam, Try including the script tag referencing the tweetgrid widget in your host HTML page directly. The reason why this won't work if you insert the script tag through an HTML widget is because GWT application load up in their own iframes. This means that references to variables that aren't properly scoped in a third party library (or in your own handwritten JavaScript code) might not be properly resolved since the window object would now refer to the iframe window rather than the main window. Placing the script tag in your host HTML page should solve this problem. If you want to interact with the embedded widget from within your GWT code (through JavaScript Native Interface methods, a.k.a. JSNI), you can do this by referring to the objects defined on the main window through the $wnd handle. You can find more documentation on using JSNI at the link below: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=DevGuideJavaScriptNativeInterface Hope that helps, -Sumit Chandel On Tue, Jan 27, 2009 at 1:32 PM, adambossy adambo...@gmail.com wrote: It just occurred to me that this pretty obviously won't work, because it is calling the script src=.../script widget tag inside of an existing script/script enclosure.

Problem with Generics and Serialization of Primitive Type Array Fields
I've been having some trouble with using arrays of primitive type
where an array of type Serializable is expected.
I have an object similar to:
class MySerializableObjectT extends Serializable implements
Serializable
{
private Serializable serializableField;
void MySerializableObject(T value)
{
serializableField= value;
}
T getField(T value)
{
return serializableField;
}
}
All of these cases can be serialized and deserialized successfully:
- new MySerializableObjectSerializable(new Integer(0));
- new MySerializableObjectSerializable(1);
- new MySerializableObjectSerializable(true);
- new MySerializableObjectSerializable(Test);
These cases case produces an exception when deserialized (Note that
these will *not* cause a class cast exception as seen in
http://code.google.com/p/google-web-toolkit/issues/detail?id=1822,
although an array of non-primitive type will cause it):
- new MySerializableObject(Serializable)((Serializable)new int[0]);
- new MySerializableObjectint[](new int[0]);
The exception's message is:
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
Type '[I' was not included in the set of types which can be
deserialized by this SerializationPolicy or its Class object could not
be loaded. For security purposes, this type will not be deserialized.
The exception goes way if I add this type to my project, even if I
don't actually create an instance of it anywhere:
class MySerializableIntArrayObject extends MySerializableObjectInt[]
{
}
I'm aware that the GWT compiler has to identify sub-types that can be
used with parameterized serializable objects during compilation in
order to build its serialization mechanism for those objects. I'm
guessing this problem means that arrays of primitive types are not
taken into account when it enumerates subtypes of Serializable,
despite the fact that they are effectively subtypes of Serializable.
If I'm correct, what is the proper way to fix this? I suppose it's
possible to create fixed-type objects like
MySerializableIntArrayObject for all primitives, but I'd like to
avoid that (especially since I would end up having to do that for any
other typed serializable objects I add in the future). If I understand
the typeArgs annotation, using it would actually restrict the set of
values I can use with this object, not add to the set (I can enumerate
the primitive array types easily enough, but not all the other types
that may be passed).
If I'm not correct about the cause of the problem, I'd appreciate it
if someone could explain it and suggest an appropriate remedy.
Thanks,

Re: Old issues in the RichTextEditor
Hi Vicente, Thanks for bumping this up. In aggregate, it seems that there are a few developers that are waiting for these enhancements to RichTextEditor, so these are definitely important to consider as we roll out future releases. I particularly bumped up Issue #1433 so the team gets to take a look at investigating it before a final 1.6 release. It seems like having support for setting innerHTML would solve the most use cases in one fix. That said, the reason why some issues go stale for as long as you pointed out in this thread is due to prioritizing the hardest hitting bugs and new features first, and dedicating effort to make sure those get shipped on time. I'm glad that you brought up this thread since it gives the community a chance to cast votes for RTE issues, a metric that we depend on for prioritizing bugs/features. Finally having said that, you know our motto, Patches welcome!. If anyone who does encounter these issues comes up with a good fix for their own purposes, it would be great to contribute that back to GWT to get quicker turnarounds on issues that the team might no have yet had a chance to work on.

Re: A possible critical bug for gwt-fabridge.
Hi Jihong,
Perhaps a more appropriate place to report this gwt-fabridge bug would be on
the project Issue Tracker. I'm sure the developers behind the project would
be happy to be notified about a potentially critical issue.
http://code.google.com/p/gwt-fabridge/issues/list
Hope that helps,

Hi. I have a problem forgwt-fabridge. I think it may be a critical
issue forgwt-fabridge.
If a swf widget is added into a panel, and then add the panel into a
container. And then remove the panel from the container, and then add
the panel back into the container. Then the Null pointer error will
occur at onInitialization()caused by the swf widget. I did a test
using
the FABridgeDemo. In the FABridgeDemo, I added a button for removing
the
swf widget.
When start the program, first click the Add new SWF, and everything
is
ok. Then click the Remove SWF, then the swf is removed. Then click
the
Add new SWF again, then an error will happen.
I have tried many ways, the only way to make it work is to create the
swf widge again and using a different name if the widget has been
removed. For example:
java.util.Date date = new java.util.Date();
swfWidget = new
SWFABridgeWidget(app.swf,400,400,example+date.getTime());
But it is not good at all. And the behavior is not the same as other
regular gwt widgets. For other widgets, after they are put in a
panel.
Then you can add/drop this panel into/from a container many times
without re-create the inside widgets.
I am really frustrated about this problem. Based on user's selection
we
will add different panels into a container for display. It is really
painful if we have to create the swf widgets again if the panel has
been
dropped from the container once.
I don't know whether the following code in
pl.rmalinowski.gwt2swf.client.ui.SWFWidge causes problem or not.
protected void onUnload() {
// GWT.log(onUnload, null);
getElement().removeChild(DOM.getFirstChild(getElement()));
isSWFInjected = false;
super.onUnload();
}
The statement:
getElement().removeChild(DOM.getFirstChild(getElement()))
removes the child from the widget. Thus after a swfwidget is removed
from a panel, and then add the swf back, no child there.
Following is the code in com.google.gwt.user.client.ui.ComplexPanel
@Override
public boolean remove(Widget w) {
// Validate.
if (w.getParent() != this) {
return false;
}
// Orphan.
orphan(w);
// Physical detach.
Element elem = w.getElement();
DOM.removeChild(DOM.getParent(elem), elem);
// Logical detach.
getChildren().remove(w);
return true;
}
It sounds to me that the different between two programs is that in
ComplexPanel, it removes the widget's element only, but in SWFWidge,
it
removes the child of the widget's element.
Thank you very much!

Re: Code Coverage with EclEmma
Hi Matt, Are you building the latest version of GWT from the SVN trunk? The team has only just recently added better support for Emma, but it is still under development. The plan is to try and get this ready for either a coming milestone or final release, but until then you're likely to encounter issues running code coverage reports. Some improvements have been added even past the 1.6 milestone, so if you would like to give Emma support another try to see how it's shaping up, you should build from the latest in trunk and run with that. As far as I know, you should still be able to use Ant or Maven or any other build system along with Emma code coverage in your GWT applications. Hope that helps, -Sumit Chandel On Tue, Feb 3, 2009 at 3:04 PM, Matt Raible mrai...@gmail.com wrote: I'm trying to get code coverage support for my GWT project.

I finally managed to get rid of the HTTP ERROR 503.

Re: Servlets and web.xml
Well you have to specify a valid url.
You are configuring /fileServlet to go to your servlet and then asking
requesting a url of /FileServlet.
Aren't you? I am not sure but think capitalization is significant.

Re: Problem with Generics and Serialization of Primitive Type Array Fields
Primitives do not extend Object and cannot implement Serializable. You
should use the Object versions of primitives (i.e. use Integer instead of
int)
I don't think the code would even compile if you tried to use a primitive
with generics.

I've been having some trouble with using arrays of primitive type

T getField(T value)

All of these cases can be serialized and deserialized successfully:

- new MySerializableObjectSerializable(true);
- new MySerializableObjectSerializable(Test);
These cases case produces an exception when deserialized (Note that
these will *not* cause a class cast exception as seen in

although an array of non-primitive type will cause it):
- new MySerializableObject(Serializable)((Serializable)new int[0]);
- new MySerializableObjectint[](new int[0]);
The exception's message is:
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
Type '[I' was not included in the set of types which can be
deserialized by this SerializationPolicy or its Class object could not
be loaded. For security purposes, this type will not be deserialized.
The exception goes way if I add this type to my project, even if I
don't actually create an instance of it anywhere:
class MySerializableIntArrayObject extends MySerializableObjectInt[]
{
}
I'm aware that the GWT compiler has to identify sub-types that can be
used with parameterized serializable objects during compilation in
order to build its serialization mechanism for those objects. I'm
guessing this problem means that arrays of primitive types are not
taken into account when it enumerates subtypes of Serializable,
despite the fact that they are effectively subtypes of Serializable.
If I'm correct, what is the proper way to fix this? I suppose it's
possible to create fixed-type objects like
MySerializableIntArrayObject for all primitives, but I'd like to
avoid that (especially since I would end up having to do that for any
other typed serializable objects I add in the future). If I understand
the typeArgs annotation, using it would actually restrict the set of
values I can use with this object, not add to the set (I can enumerate
the primitive array types easily enough, but not all the other types
that may be passed).
If I'm not correct about the cause of the problem, I'd appreciate it
if someone could explain it and suggest an appropriate remedy.
Thanks,
-jsegal

Google ( App Engine + Web Toolkit )
Hi Guys, I wanted to know what are the prospects of using Google App Engine with the Web Toolkit. I did some searches and read up on the documentation, it seems that the only way is to do JSON data transmission layer in the middle. I am no expert, just wanted to play with these two technologies, so please correct me if I am wrong. What about Django then? I guess I wont be needing that anymore, all I have to do is make a Google App Engine server to send JSON responses to all the custom requests the Web Toolkit client sends. Currently, App Engine is only supported in python, once they support it in Java, will it help in anyway with the Web Toolkit, I found some details about RPC and transferring actual Java serializable objects, will that eliminate the JSON layer? Any help and details in this respect are more than welcome. Thanks, Omer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Google ( App Engine + Web Toolkit )
Thanks Shawn. Okay, Django will help me convert python objects to JSON, and at the GWT end, you can use a standard JSON Parser, but besides that, all of the rest you will never ever use, correct? Nothing wrong with that, but was just curious, all this Django capabilities are of no use to you all of a sudden. I havent looked too much in GWT yet, but I am sure it will cover for the empty space well. In general, would you recommend GWT + App Engine for developing something, although there are many plus points in creating this division between client and server end, but there are some hurdles too: what about user logins? will you have to develop it all at client end too? How would you do user authentication the App Engine way which was really straight forward before? I would like to explore these hurdles and questions before I jump in. Both of them are really powerful alone, but together, do they make a good system or is it just too much hassle? Thanks in advance for your input and thoughts.

Re: Google ( App Engine + Web Toolkit )
At this point I really don't know. GWT + json works fine for me using DWR. I can throw GWT under appengine at the moment calling my java sevlets for authentication and data requests. To convert the servlets to python and run it all under appengine -- I don't know that would take. Sorry. On Sat, Feb 7, 2009 at 1:01 PM, Omer Shakil omer.sha...@gmail.com wrote: Thanks Shawn.

how to set the size of a dialog box with respect to the flex table inside it?
Hi! I'm quite new with gwt and I have a simple yet annoying problem. I want to show a dialog box that contains a flex table that adjusts according to the columns and rows of data. I tried getting the offset height and width of flex table but it gives me a value of 0. I also tried to set the dialog box to auto width and auto height but what happened is that the dialog box stretched to the maximum possible and it didn't follow the size of the flex table inside it (which only filled 30% of the total width of the resulting dialog box). Is there a way for me to make the dialog box listen or adjust its size with respect to the widget inside it, in this case, the flex table? I would really appreciate your help.

Fixes squirrely case where calling PopupPanel.hide() appears to get into a
race
condition when it calls onUnload(), which calls hide() again. This is now
cleaned up to only do strictly-necessary cleanup work in onUnload(), and a
test
added to ensure it works properly in practice.

[gwt-contrib] Work around for gwt issue 3340
Reviewers: jgw,
Description:
issue url:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3340
This work around stops a race condition from happening in IE that causes
the image not to be cached correctly if the onLoad event is hooked up to
the image immediately after the image is added to the dom.
For the next release of GWT, we should canonically solve this problem
instead of working around it, so we can get reliable load events on all
browsers.

[gwt-contrib] Re: Announcing GWT 1.6 Milestone 1
Scott et. al, Great release! I spent a few hours migrating our codebase and build process without much trouble. 1. The new expanded WAR format makes life a lot easier for us to run with -noserver. With 1.5, we had to regenerate the hosted.html and nocache.js files every time something changed. Now we're just pointing Tomcat at war/ and letting tomcat serve them directly. 2. The compiler task crashes Java 1.6 on Mac now. The previous versions would run fine with the 64-bit JVM (even though SWT isn't compatible). Would it be possible to lazy load SWT so that we can take advantage of the faster 1.6 JVM on OSX? [java] Invalid memory access of location rip=01160767 3. Our final output codesize grew by ~2-3% (compressed size). Scanning the symbol files seems to point towards a bunch of new event handling classes that showed up. I haven't ported all of our widgets over to using handlers instead of listeners, so it's likely a result of some code duplication as well. 4. None of our custom linkers required major work to bring it up to date, with the exception of some tweaks to add a third parameter to window.external.gwtOnload(). 5. One cool thing that was missing from the release notes is new the ability to specify multiple modules for the compile task. Based on some wallclock testing, specifying multiple modules shaves off ~30 seconds off compile time of any modules on top of the first: Individual times: [java]Compilation succeeded -- 51.814s [java]Compilation succeeded -- 170.986s [java]Compilation succeeded -- 91.488s All together: [java]Compilation succeeded -- 55.121s [java] Compilation succeeded -- 141.052s [java] Compilation succeeded -- 55.492s Note that each module's log messages are indented one level further, indicating the extra speed boost. ;) Overall, an awesome release. Thanks, all. Matt. On 4-Feb-09, at 5:34 PM, Scott Blum wrote: Greetings GWT developers, The GWT team is happy to announce the availability of 1.6 Milestone 1! Binary distributions are available for download directly from GWT's Google Code project. http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=1.6.0 As always, milestone builds like this are use-at-your-own-risk. There are known bugs, and it definitely isn't ready for production use. Please expect some trial and error getting everything to work. The javadoc that comes bundled with the distribution should be up-to- date, but the online Developer Guide (http://code.google.com/docreader/#p =google-web-toolkit-doc-1-6) is still very much a work in progress. We will be updating it over the next several weeks. In lieu of an up- to-date Developer Guide and release notes, below are the major highlights relative to GWT 1.5.3. *** New Project Structure in GWT 1.6 *** One of the biggest changes to GWT 1.6 is a new project structure. The old output format has been replaced by the standard Java web app expanded war format, and the actual directory name does default to /war. Note that the war directory is not only for compiler output; it is also intended to contain handwritten static resources that you want to be included in your webapp alongside GWT modules (that is, things you'd want to version control). Please also note that the GWTShell and GWTCompiler tools will maintain their legacy behavior, but they have been deprecated in favor of new HostedMode and Compiler tools which use the new war output. When 1.6 is officially released, we will be encouraging existing projects to update to the new directory format and to use the new tools to take advantage of new features and for compatibility with future GWT releases. The sample projects provided in the GWT distribution provide an example of correct new project configurations. For more details on the specifics of the new project format, please see GWT 1.6 WAR design document (http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6 ). A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep

[gwt-contrib] Google API Libraries for GWT: New binaries ready for download
Another round of updates is ready for the Google API Libraries for Google Web Toolkit (GWT). As just announced on the GWT blog, this update brings bug fixes and new features to three of the existing libraries. - The Google Visualization API Library for GWT moves from a release candidate to a public release with a few bug fixes. - The Gadgets API Library for GWT now supports GadgetAds , gadget based internationalization and an important bug fix for Windows developers using GWT hosted mode. - The Google Maps API Library for GWT now includes support for the GAdsManager and reverse geocoding support. We are also announcing a major update as a release candidate. The Gears API Library for GWT version 1.2.0 supports the Gears 0.4 feature set, which includes Geolocation, HTTP Request, Desktop and Blob. This release is exciting to me not just for the new features that have been added, but also for the number of new contributors to the libraries from the open source community. Special thanks to Mark Renouf for contributing Gears 0.4 support, and all those that filed issues and contributed patches. You can find the new libraries ready for download on Google Code. http://code.google.com/p/gwt-google-apis -- Eric Z.

[java] Invalid memory access of location rip=01160767 Good point, I can take a look at this. The compiler should be able to run without loading SWT. 5. One cool thing that was missing from the release notes is new the ability to specify multiple modules for the compile task. Based on some wallclock testing, specifying multiple modules shaves off ~30 seconds off compile time of any modules on top of the first: Individual times: [java]Compilation succeeded -- 51.814s [java]Compilation succeeded -- 170.986s [java]Compilation succeeded -- 91.488s All together: [java]Compilation succeeded -- 55.121s [java] Compilation succeeded -- 141.052s [java] Compilation succeeded -- 55.492s Note that each module's log messages are indented one level further, indicating the extra speed boost. ;) LOL!

This disables: - Class.getName() - returns Class$hashCode() - Class.getSuperclass() - returns null - Class.toString() - returns Object.toString() You can still use class.getName() as an equality comparison, but not for anything that requires semantic meaning; the relationships between the strings will be constant throughout the lifetime of the module. A.class == A.class != B.class A.class.getName() == A.class.getName() != B.class.getName() With this flag enabled, class literal setup for non-enum types is a simple JS new operation.
