Re: how to deploy a GWT Application online?
Hi sam, I think you have completed your gwt application in your local machine with mysql database.So I think its working fine in your local machine [in eclipse editor].You now create a war for the entire project ie it contains all codes of client and server and should put into the webapps of tomcat server or corresponding location of any other server ie jboss or weblogic or anything.And you can take the url in any browzer.please make sure the client and server codes[class files] in a single war.

I have a ListBox with a heading that looks like this:
___Name___|__Location__
I add to the ListBox (maybe) several strings that I have built up from
two pieces of data: a name and a city/town name. I need the resulting
string to display such that the city/town name begins just one space
into the location part of the display. I have a method to padString
which I use to pad out the length of the name plus as many spaces as
required to put the location at the right place once appended to the
name+spaces part of the string.
This approach does not work because the browser ignors multiple spaces
and treats them as one, so I lose my padding. This application is a
conversion from the same app written using HTML and javaScript. In
that version I was successful in establishing the pad because I
appended a number of nbsp; (non-breaking space) rather than plain
spaces.
Presently, I am padding with underscores to be able to see how this is
working, and that it is working. I can see the padding is working
okay but the font is a variable width font and the result is a
staggered text display, depending on the number of and specific
characters in the name part.
Now, There may be a way for me to add non-breaking spaces rather than
plain spaces as padding. How might I do that? Even so, I will
probably have to set the font in the ListBox to a momospaced font so I
get exact apacing of every character. I know there is a problem
setting a font using css in a GWT app.
Here is the relevant part of my current css for this problem:
.gwt-ListBox-selectList {
white-space: pre;
background: lightgray;
}
The 'pre' doesn't work, either. As best I can tell this is a browser
problem. I am using Firefox version 1.5.0.12.
Suggestions, please?

Re: Calling GWT applications from legacy applications
Hello, Not sure about your question - If you want to include GWT client code in your jsp, just modify your jsp template adding the javascript tag that points to your gwt application. - If you want to put this client code in the same context of your legacy application, - put the static stuff produced by gwt-compiler in the public folder of the application - or include your gwt java classes in the application, configure the build classpath to include gwt stuff, and modify your build script to compile gwt client code before producing your .war file - If you use rpcs calling server code, you can put these classes and necessary libraries in your legacy application without problem.

Re: Hibernate GWT
For Gilead, you don't need to inherit from their classes. Have your model objects implement ILightEntity. It's basically a wrapper around a simple hashmap to store the proxy information. Your service can use the GileadRPCHelper directly.Take a look at the implementation of PersistentRemoteService. Our projects are structured this way and it works great. One gotcha with Gilead. It seems to play well with either a servlet container or JBOSS. We are using it with GlassFish and it took some tweaking to get everything running. On Aug 4, 10:33 am, javier jasand...@gmail.com wrote: Hello folks: I've posted this question to the Hibernate user's forum, but in the absence of replies, I am posting it here as well, in the hopes that some of you may shed some light. Please accept my apologies if this is the second time you see this post. I'm about to engage in an enterprise project whose front-end is to be built with GWT. I've had some Hibernate experience from past projects and really like the ORM mechanism used by Hibernate for marshalling/ unmarshalling from a database. Now, as some of you know, domain entities need to be transferred over the wire for GWT's consumption: entities that have been instrumented with persistence information will fail at the client side, as GWT cannot handle these objects. So I've done some research and I've come across two common solutions to this problem: 1) Using a framework called Gilead; 2) Replicating the domain model hierarchy with a second class hierarchy used exclusively for data transfer (aka Data Transfer Objects representing the persistent domain objects). None of these solutions are good in my current situation: 1) Gilead intrudes into the design of an application by forcing the entities to inherit from “LightEntity” and forcing RemoteServiceServlet descendants to extend “PersistentRemoteService”. Our design cannot allow this, as both of these type of objects already inherit from a different hierarchy. 2) Our domain model is composed of 30 classes, some of which have quite a few getters/setters. Replicating this domain model sounds like trip to maintenance nightmare street, not to mention the amount of extra code that we'll need to map things back-and-forth. So even though I know (from experience) that Hibernate will make me a lot more productive accessing the database than the alternative (ie hand-coding with JDBC), all this productivity goes down the drain if I now have to deal with recreating the objects in order to properly talk to the client layer. So now my question is, can I get away with the following: 1) make every single persistent entity to always load everything eagerly by default (ie lazy=”false”) and make lazy loading the exception to the rule (ie when fetching lists of things); 2) use a stateless Session-per-request approach, so that every time I need something from the db a brand new persistence context is initialized. I understand that I'll be giving up caching and hence, taking a performance hit, what I'd like to know is, how bad is this hit? is this an acceptable compromise in my case? Is this approach still better than going back to manual JDBC days? Please advise if this is a horrible approach and if there is something I should know before I put a rope around my neck.

Linux 64bits package?
Hi. I am using Linux 64-Bit (Ubuntu 9.04) with the provided JDK 6 from Sun. Is it planned a 64-Bit distro for GWT? Or, as alternative, is GWT 1.7 Out-of-process-hosted-mode ready? The reason why I am asking, ist that with this configuration, the -d32 option in JDK is not working, I think it's an Ubuntu package bug, and this leads to problems; for example, using hosted mode with maven. P.S. I already found this : http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/1b179436b29804ac/f2ce63af5a3870e9?lnk=gstq=64+bit#f2ce63af5a3870e9 But I am writing to say that ia32-sun-java6-bin doesn't solve all the problems: when you have to compile+run, the 32 bit JRE is not enough Thanks.

Re: How to determine pixel size of Label widget at run time?
Unless you set the label to display:block it will expand to the width of its container (it is actually a div). With display:block it will just be as wide as it needs. Why can't you move it once it is added? Ian http://examples.roughian.com 2009/8/17 Mike Jacobs mike.jac...@indietechnologies.com Once I added the label to the intended container (the map pane in the Google map API), the width was calculated correctly. Since I cannot move the widget once it has been added, I add it to get the dimensions and then remove it before adding it where it belongs. Thanks for the help. Mike On Aug 17, 7:27 am, Mike Jacobs mike.jac...@indietechnologies.com wrote: The label offset width is zero prior to adding to the root panel and unusually large after adding it. The width is supposedly 761 for a string of ~~testing~~. I will experiment with this a bit more but this width seems like it might be the width of the root panel at the time.

Ian http://examples.roughian.com 2009/8/16 Mike Jacobs mike.jac...@indietechnologies.com I have a case where I am dynamically adding a Label widget with program determined label text. (It is adding a Label on top of a Google Map but this question is about GWT widgets). Since the label text can vary at run time and I would like to center the label at a specific pixel location, I need to figure out the pixel size of the label to position it properly. I can specify a pixel width and height when creating the Label. Is it possible to determine the appropriate size of the Label based on the label text length? Is is possible to ask the label for it's pixel size afterward instead? I have been using a simple approach of using width = text length * 11 (since the font is 11px) but that appears to be off by a few pixels presumably due to varying width of characters.

Re: formating ListBox text
Hm ... The data, name and location, are two fields of a database row. I retrieve several (related) at a time from the database and put the two key fields into the ListBox and then select which one I want to use thereby selecting the rest of the fields from the database record to display in other TextBoxes on the page. ListBox seems just the right thing for that. However, if I can select from a table and use the index (row number) from the selection to pick off (out of an array) the record containing the other fields to display that would certainly work. I will look into that. Thanks.

Re: Where is the server log ?
This isnt a direct answer to your question but i think that this is
the root of what is going wrong. Class instances that you send to the
client have to play by the rules of GWT. The class cant have imports
that are not available on the javascript runtime code.
import javax.persistence.Entity;

those classes are almost certainly not in the limited environment.

Re: formating ListBox text
No, appending HTML nbsp to a string doesn't work to solve my problem. However, I have found if I append a period and a space (sort of as a single character) each space is retained because of the protecting period, I can get close enough for my purposes. If I could now set the font to a monospced font like Courier, I would be home free, I think; but that seems not to be possible at present. I feel like I have solved my problem, for now. (Kind of sloppy, but it works.) Thank you.

Re: GWT-Maps - Is this a desired behavior?
Hi Paul,
Take a look at this demo in JavaScript:
http://code.google.com/apis/maps/documentation/overlays.html#Custom_Overlays
The demo code is called 'CustomOverlayDemo' in the HelloMaps API demo
I think part of the problem is that your code draws into the viewport
with pixel values - you need to work with lat-lng values for things to
correctly drag around in the map. Also, you are re-creating the divs
inside of redraw() - the should be created in initialize().

BTW, though I'm not sure why you are getting your exceptions, here''s a way
to add rows anywhere - you'd need two versions - one for adding a level-2
flextable to a level-1 flextable, and another to deal with adding rows to
your level-2 flextable. And you'd probably be better off with labels styled

Re: How to split a large application?
Hello David, hey folks, we figure exactly the scenario you describe here with our application. It's similar to a portal based application as you describe it. Basically, what we struggle with: Say we compile the main application with some portlets pre-installed resulting in a single JS file. We also provide additional modules/portlets that the user might want to install. These modules, however, have a completely different lifecycle than the rest of the portal. Now, if we'd compile the additional portlets one by one, wouldn't that result in a whole bunch of duplicated JS code e.g. for JRE emulated classes? Next, the JS code is of course obfuscated so the names of our Java types vary from compilation to compilation. If I'd compile each module separately it wouldn't find any existing class from the portal application. Even worse, I thought it would just duplicate the portal applications classes into the portlet JS code (of course, assuming we have a call dependency to the portal application). The only solution to this problem we currently think of is to trigger a complete re-compilation of the app at runtime. For instance, we try to implement a registry where each module/portlet Jar registers and once the registry detects changes it triggers re-compilation of the complete javascript files. We'd likely do that in a servlet context listener or something equivalent. Has anyone tried something similar already? Has anyone similar problems and/or other solutions? Thanks! On 11 Aug., 14:41, David david.no...@gmail.com wrote: Nathan, The use case is indeed not what you think it is. In your case I could just deliver the main application as a widget library and build the final application from this jar. It is not possible tocompileboth the main application and child applications in one unit because these are developed by different groups/companies. The sub applications are installed separately from the main applications and the main application is updated separately from the sub applications as well. When you create a portal you don't always write/compileall the portlets that are being deployed. Per installation the version and type of portlets can also be different so it is just impossible to deliver everything as one big application. We do not host the service either, so the portal is delivered as an ear that will allow appserver admins to configure the installed applications at runtime. So we just don't know what applications are used and they are not even from our group/company.

Creating Reuseable Modules
GWT comes with default CSS. If I create a bunch of reuseable Modules (packaged as Jars for use by some of our other internal development teams) with our own corporate style, the compiled application loads 2 stylesheets (the default, and company for example). If one of our development teams uses those Modules to create a new app and adds some CSS specific to that app the compiled application loads 3 stylesheets (default, company and application). These stylesheets are not minified or combined, this can't be correct as Google's own page performance tool states that HTTP requests should be reduced and css files combinded - I must be doing something wrong? However, one of the GWT example apps I've seen is loading over 1Mb data in 59 http requests and takes about 11 secs to load... Can anyone point me at a good tutorial on how to create reuseable modules that don't break web app performance best practices? Thanks.

Re: Who is using smartgwt?
Sorry Tercio, I can't spend more time helping you understand the architecture here, but suffice it to say, try building the example I suggested (drag and drop between two very large user groups that can't be loaded in advance) and you'll see why widget-specific caches are an absolute necessity. Each widget is looking at a particular subset of the data available from the model, managed by a ResultSet which serves as a projection of the model data needed for that particular view. You will find the same approach in every system that handles large datasets, from Swing to JDBC and everywhere else - it's really worth your time to investigate this and understand it. I'd also appreciate it if you could stop asserting things that are just clearly false. SmartGWT has many, many Java override points that allow you to deeply customize behavior - not getters/setters but fundamentals like which cells are editable (listGrid.canEditCell()), how data is transmitted (various DataSource APIs), many aspects of how HTML is generated (getInnerHTML, cellFormatters, many others), and of course, countless events. I think you have some misconceptions which date back to right after 1.0 was released - not every override point from SmartClient is yet available in SmartGWT, but we are getting closer to that all the time. On Aug 16, 8:45 pm, Tercio Filho terciofi...@gmail.com wrote: On Aug 16, 7:39 pm, ckendrick charles.kendr...@gmail.com wrote: @tercio You're still missing the key point. Let's try again: It is absolutely 100% required in an enterprise application that different components have different caches, potentially partially overlapping, on the same dataset. A simple example is an interface for dragging and drop users between two different groups where both groups are very large and cannot be loaded in their entirety. In SmartGWT this is a single DataSource, and two ResultSets on that DataSource. Each ResultSet loads the first batch of members of each group and is capable of paging in the rest as needed. As I said in my first post, we cannot compare SmartGWT DataSource with the GXT Store, as they do different jobs, DataSource in SmartGWT is just a Proxy, or in GXT the Loader and the Reader, that's the function of the DataSource in SmartGWT, retrieve data when somebody need it. It is not a drawback that SmartGWT has separate caches per component. It's the correct architecture, and is a necessity where large datasets are involved. I disagree that this is the right way to do things, I cannot accept the fact that the widget manages it's data cache, widget is just a widget, it has nothing to do with model data. As I mentioned previously, if the datasets involved are small, you can use a clientOnly DataSource, and then there is only one central cache. This is the trivial case, which is the only one GXT currently handles. In either case (clientOnly or not) APIs exist in SmartGWT that allow fetching data directly from the DataSource without the use of a component - you can both call methods like DataSource.fetchData(), or you can directly create a ResultSet. Coupling problem, why should I, a data manipulator, must care about this?? I just need the data, that's why the GXT Store is better, you have a store, a reader and a loader, layers of decoupling. One taking care of another... Once you've absorbed all this, I think you will agree, the SmartGWT architecture is the correct one and the GXT architecture has limitations. Another mistatements: in SmartGWT you can extend the built-in widgets and other classes and override methods. People do this all the time. And you CAN'T change a widget behavior in SmartGWT, at least in Java... you have a lot of methods that you can override, but it's just property setter/getters for JS code, it's internal behavior is inside JS code, so, no go. Even extend is uncertain. I have no idea why you think more code would be involved with SmartGWT for server integration. People constantly say the reverse. There may other misconceptions there that I could address, if you were to explain why you think this is. About the server code I mentioned, i didn't made myself clear, I'd like to say exactly this(Less work for the developer). I wish I have a better english.. :-P Regardless, most professional, enterprise developers can easily justify a purchase of SmartGWT Pro, where the amount of SmartGWT-specific server code involved is literally zero for many cases, and very small for the others. Sure, a professional can justify, I didn't said the opposite. Anyways, let's see what Chris think about all this, it's all about point of view.

Suddenly getting exceptions during compile in TypeOracle annotation processing
I'm suddenly getting strange exceptions when compiling my application that uses EJB3 objects with annotations and Gilead. The exceptions seems to happen for different annotation objects each time, however it's always for the same reason: NPE in the TypeOracleMediator. I've tried this with the old version of Gilead (Hibernate4gwt 1.1.1) and with the new version. I've also tried this with GWT 1.6.4, and 1.7.0. In every case it's giving me the same NPE. Nothing significant has changed in my code, I've just made some general improvements over the last few days which are working find in hosted mode. However compile seems to be screwed up.

Re: Who is using smartgwt?
ckendrick, is canEditCell() a behavior or a feature?
protected native boolean canEditCell(int rowNum, int colNum) /*-{
var self =

return self._canEditCell(rowNum, colNum);

Damn, it's behavior is inside JS code.
I'm not saying that a widget cannot have a cache, I'm saying it just
can't manage it, well, it can, but shouldn't...

Tercio.

Sorry Tercio, I can't spend more time helping you understand the
architecture here, but suffice it to say, try building the example I
suggested (drag and drop between two very large user groups that can't
be loaded in advance) and you'll see why widget-specific caches are an
absolute necessity.
Each widget is looking at a particular subset of the data available
from the model, managed by a ResultSet which serves as a projection of
the model data needed for that particular view. You will find the
same approach in every system that handles large datasets, from Swing
to JDBC and everywhere else - it's really worth your time to
investigate this and understand it.
I'd also appreciate it if you could stop asserting things that are
just clearly false. SmartGWT has many, many Java override points that
allow you to deeply customize behavior - not getters/setters but
fundamentals like which cells are editable (listGrid.canEditCell()),
how data is transmitted (various DataSource APIs), many aspects of how
HTML is generated (getInnerHTML, cellFormatters, many others), and of
course, countless events. I think you have some misconceptions which
date back to right after 1.0 was released - not every override point
from SmartClient is yet available in SmartGWT, but we are getting
closer to that all the time.

@tercio You're still missing the key point. Let's try again:
It is absolutely 100% required in an enterprise application that
different components have different caches, potentially partially
overlapping, on the same dataset. A simple example is an interface
for dragging and drop users between two different groups where both
groups are very large and cannot be loaded in their entirety. In
SmartGWT this is a single DataSource, and two ResultSets on that
DataSource. Each ResultSet loads the first batch of members of each
group and is capable of paging in the rest as needed.
As I said in my first post, we cannot compare SmartGWT DataSource with
the GXT Store, as they do different jobs, DataSource in SmartGWT is
just a Proxy, or in GXT the Loader and the Reader, that's the function
of the DataSource in SmartGWT, retrieve data when somebody need it.
It is not a drawback that SmartGWT has separate caches per component.
It's the correct architecture, and is a necessity where large datasets
are involved.
I disagree that this is the right way to do things, I cannot accept
the fact that the widget manages it's data cache, widget is just a
widget, it has nothing to do with model data.
As I mentioned previously, if the datasets involved are small, you can
use a clientOnly DataSource, and then there is only one central
cache. This is the trivial case, which is the only one GXT currently
handles.
In either case (clientOnly or not) APIs exist in SmartGWT that allow
fetching data directly from the DataSource without the use of a
component - you can both call methods like DataSource.fetchData(), or
you can directly create a ResultSet.
Coupling problem, why should I, a data manipulator, must care about
this?? I just need the data, that's why the GXT Store is better, you
have a store, a reader and a loader, layers of decoupling. One taking
care of another...
Once you've absorbed all this, I think you will agree, the SmartGWT
architecture is the correct one and the GXT architecture has
limitations.
Another mistatements: in SmartGWT you can extend the built-in widgets
and other classes and override methods. People do this all the time.
And you CAN'T change a widget behavior in SmartGWT, at least in
Java... you have a lot of methods that you can override, but it's just
property setter/getters for JS code, it's internal behavior is inside
JS code, so, no go. Even extend is uncertain.
I have no idea why you think more code would be involved with SmartGWT
for server integration. People constantly say the reverse. There may
other misconceptions there that I could address, if you were to
explain why you think this is.
About the server code I mentioned, i didn't made myself clear, I'd
like to say exactly this(Less work for the developer). I wish I have a
better english.. :-P

Hi Paul,
Take a look at this demo in JavaScript:

The demo code is called 'CustomOverlayDemo' in the HelloMaps API demo
I think part of the problem is that your code draws into the viewport

correctly drag around in the map. Also, you are re-creating the divs

Re: Compilation failing
What OS are you developing in? What browser are you testing the compiled code in? I suspect that you are not developing in Windows and are testing compiled code in IE. IE will report errors that other browsers don't (yeah I know 'typical IE', but there again if it didn't report errors when it should that would be 'typical IE' too). If that is the case, then you need to compile with the -PRETTY option and find out where the error is. Or try it on a Windows machine where you will get a proper error report.

Hi thanks for the reply I am using an Windows XP machine and i am developing in Eclipse using the GWT toolkit. I am using the default google explorer which one gets while using the hosted mode. Everything was running perfectly while i was running it. But when i clicked on the Compile/Browse button the application gave me this error. The error is happenning in the following part of functionality. I am parsing an xml document and storing its attributes in a string.Then i am reading an substring from the main string. The line says string out of index ( from searching on google) says that there is no character of the string on that place. When checked now, the is no value being stored presently in the string variable, which is odd, because i created backup of the application before hitting on compile/browse button and its still working fine with no errors. any ideas how should i proceed.

Re: Creating and Importing GWT Independent Modules
Yeah! It worked! Sorry for the waiting, there was a reshuffle and I was working in another project for a little while. But your step by step guide is very useful, and the discussion heped me too. I followed your steps and got the class acessible in the main project, but when I booted it, I got a nasty null pointer exception, so when I read your next post : Only code that can be cross-compiled into JavaScript should be used when performing a GWT compilation , I realized how obvious the solution was. I don't know yet if there are any other ways ( I believe there is ) , but I made my class to implement the EntryPoint, the everything gone smoothly well. I left the onModuleLoad method empty.

Re: Creating and Importing GWT Independent Modules
I am not a GWT expert, but I don't think this is possible. But if you want to make life easier you could use a ant task to automate those jar builds, copying, and classpath updating. With ant you can do most anything you could with a ShellScript, you know, java project wise. To help debugging, you can export every jar with the sources inside, there is a checkbox on the eclipse Jar export wizard. Boa sorte!

Re: Creating Reuseable Modules
Yeah I know the feeling, My app was taking around 20-30 seconds to load for the first time - after the first load it was nearly instant I've tested with Google Page Speed and Page Activity as well, and I come to realize that the biggest problem is the huge amount of JS scrips ( at least for me ), Gzip compression helped a lot, in my case, around 7-10 seconds. As the GWT application itself is just pure JS in the client side, a solution I've used that helped a lot the user experience, is to load the application in the background. In my case, I load the login screen first - and it does it very quickly, around 1-2 second(s) - and while the user is still logging in the application I load all the other parts of the application, starting from the parts I think the user will use first. So while the user logs in, and take a look to the main page, all the application is loading without his perception - except for the firefox status spinner : P And then 10-15 seconds comes to be a acceptable time, since my users take just around that time to make a login and try to use any other funcionality after doing it. But of course, I agree that GWT could be better in both performance and best practices, but if you look at the generated code, you will see that that ship is sailed. The browsers are not so compliant to the standards as they could, and the guys from the GWT team can't do miracles. Take a look at gzip compression and and partitioned loading for gwt apps, I know I didn't actually answered you question, but this might help your performance. Good luck! On 17 ago, 07:12, Rodders david.andrew.chap...@googlemail.com wrote: GWT comes with default CSS. If I create a bunch of reuseable Modules (packaged as Jars for use by some of our other internal development teams) with our own corporate style, the compiled application loads 2 stylesheets (the default, and company for example). If one of our development teams uses those Modules to create a new app and adds some CSS specific to that app the compiled application loads 3 stylesheets (default, company and application). These stylesheets are not minified or combined, this can't be correct as Google's own page performance tool states that HTTP requests should be reduced and css files combinded - I must be doing something wrong? However, one of the GWT example apps I've seen is loading over 1Mb data in 59 http requests and takes about 11 secs to load... Can anyone point me at a good tutorial on how to create reuseable modules that don't break web app performance best practices? Thanks.

If that is the case, then you need to compile with the -PRETTY option and find out where the error is. Or try it on a Windows machine where you will get a proper error report.

Re: Linux 64bits package?
Rajeev Dayal says: ... the next release of GWT will no longer require that you use a 32-bit JVM. It will support a mode of execution known as Out-of-process-hosted-mode. Instead of debugging your application using the hosted browser, you'll be able to debug it while it runs in a real browser. Since the hosted browser will no longer be required, neither will the 32-bit SWT libraries that we bundle. If you're adventurous, you can try out this functionality right now - check out the GWT source, and do a trunk build. It should work with the plugin. Good luck! On 17 ago, 08:59, Luigi R.

Re: ImageBundle using AlphaImageLoader don't allow events to fire properly
Thanks for reporting this, Damon. For what it's worth, this shouldn't be an

On Thu, Aug 13, 2009 at 8:42 AM, Damon Lundin damon.lun...@gmail.comwrote:
On IE6, we've run into a problem that we don't know how to work
around. If you create an ImageBundle and use it for buttons in your
application, you will run into problems where clicking on the image
does not fire all the events that it's supposed to. In particular,
the blur event does not get fired.
I have distilled the problem to some basic HTML which will show you
the problem:
The code below is essentially what you get when using an ImageBundle.
If you put focus on the input field and then click the image, the text
box does not lose focus and the blur event does not get fired. If you
click anywhere but the image, the blur event will get fired. If you
use a .gif instead of a .png and the AlphaImageLoader, clicking the
image will cause the blur event to fire. Note that the problem is not
that clicking the image fires no events. If you add an onClick
handler below, it will fire. It just won't fire the blur event. This
is particularly troublesome if your code relies on the blur event to
update your model before handling the click event on the button. In
this case, the click event fires but the blur does not and your click
handler gets a model that's not updated yet (of course we could design
our click handlers to force an update but that's easier said than done
in our application).
Does anyone know of any tricks to work around this? I know there are
some position tricks people use to make links clickable inside such an
area, but here all we have is an img that does have any nested
elements. Is there a way to have the ImageBundle compiler create
a .gif instead of a .png (assuming all the images were .gifs in the
first place)?

First problem is that you are asking a JavaScript question in a GWT group

Second problem is that your webpage will loop, endlessly loading and
reloading. This a pretty basic a mistake, so maybe it would be a good idea
to search for some JavaScript tutorials or sign up to a JavaScript

Sinking new HTML 5 DOM events?
GWT is a really clever piece of compiler technology!
I'm currently experimenting with HTML 5's video/ tag and GWT. For
the most part, this was very easy to get running. But event-handling
has been a major headache.
In particular, I'm trying to add a listener to ontimeupdate, which
is called whenever the current playback time changes. In JavaScript,
the code would look this:
# Tested in Firefox 3.5. (Will generate tons of alerts. Be
warned.)
var video = document.getElementsByTagName('video')[0];
video.addEventListener(timeupdate, function (event) {
window.alert(Time: + video.currentTime);
}, true);
I've defined an appropriate set of classes (TimeUpdateEvent,
TimeUpdateHandler) and added a addTimeUpdateHandler function to my
Video widget. But this isn't enough to make things work--my timeupdate
handler is never called. (Code is attached below.)
Further investigation reveals that I'm still missing quite a few
pieces:
DOMImpl::eventGetTypeInt - I need to add an entry for timeupdate.
DOMImpl::sinkEvents - I need to call addEventListener
(timeupdate, ..., true).
Event - I need to add a ONTIMEUPDATE constant.
Is there an easy way to work around this without patching my local
copy of GWT? And would it be worth either (a) making the list of
events extensible at runtime, or (b) adding a list of events taken
from the HTML 5 standard?
Thank you for such an interesting toolkit, and for any advice you can
provide on supporting custom DOM events!
Cheers,
Eric
=== begin Java code ===
public class Video extends FocusWidget {
// ... lots of code removed
public HandlerRegistration addTimeUpdateHandler(TimeUpdateHandler
handler) {
return addHandler(handler, TimeUpdateEvent.getType());
}
}
public interface TimeUpdateHandler extends EventHandler {
void onTimeUpdate(TimeUpdateEvent event);
}
public class TimeUpdateEvent extends DomEventTimeUpdateHandler {
private static final TypeTimeUpdateHandler TYPE =
new TypeTimeUpdateHandler(timeupdate, new
TimeUpdateEvent());
public static TypeTimeUpdateHandler getType() {
return TYPE;
}
@Override
public TypeTimeUpdateHandler getAssociatedType() {
return TYPE;
}
@Override
protected void dispatch(TimeUpdateHandler handler) {
handler.onTimeUpdate(this);
}

Re: GWT Deployment on Web Hosting Sites
Hi Kenneth, As Dobes mentioned, you can definitely use any hosting service, like GoDaddy, to deploy your GWT application. Also as mentioned, GWT generates regular JavaScript and HTML files than any hosting service provider should be able to handle. If you're using GWT RPC, you will need a hosting service that provides a Java server-side environment, supporting the Servlet 2.5 specification. For more details on all the moving parts of a deployed GWT application, both with an RPC backend and without, check out the deployment documentation at the link below.

Re: Struts 1.2 and gwt
Hi suzy, There is nothing stopping you from using GWT in your Struts application. One point of conflict I could think of is controlling application flow, as Struts does seem to prescribe a Web 1.0 style navigation flow, however you can definitely add GWT components to your existing Struts pages to enhance them. In your case, it seems like you simply want to use GWT to display data within your Struts page. You can do this by simply coding up your GWT component (both the widget layout and style itself along with the logic to grab the data to be displayed from the page), and binding the component to an element in your Struts page. You can read more details about how to bind the component to your Struts page in the documentation linked below.

SmartGWT 1.2 Tile Sort Filtering Example Question Fuzzy Search / (Maybe Bug)?
Hi everybody,
I am just new to GWT and experiencing a little bit with SmartGWT,
implementing and trying to change the Tile Sort Filtering Example
from the Showcase
http://www.smartclient.com/smartgwt/showcase/#featured_tile_filtering
I am trying to implement the above example with a fuzzy search but
without the extra SearchItems, which causes the FuzzySearch to fail
and draw back on an EQUALS search.
Everything works fine with the example, but here comes my 'error' /
'bug' :
Here is an excerpt from the code from the showcase example:
code
final DynamicForm filterForm = new DynamicForm();
filterForm.setIsGroup(true);
filterForm.setGroupTitle(Search);
filterForm.setNumCols(6);
filterForm.setDataSource(AnimalXmlDS.getInstance());
filterForm.setAutoFocus(false);
TextItem commonNameItem = new TextItem(commonName);
SliderItem lifeSpanItem = new SliderItem(lifeSpan);
lifeSpanItem.setTitle(Max Life Span);
lifeSpanItem.setMinValue(1);
lifeSpanItem.setMaxValue(60);
lifeSpanItem.setDefaultValue(60);
lifeSpanItem.setHeight(50);
lifeSpanItem.setOperator(OperatorId.LESS_THAN);
SelectItem statusItem = new SelectItem(status);
statusItem.setOperator(OperatorId.EQUALS);
statusItem.setAllowEmptyValue(true);
filterForm.setFields(commonNameItem, lifeSpanItem,
statusItem);
filterForm.addItemChangedHandler(new ItemChangedHandler() {
public void onItemChanged(ItemChangedEvent event) {
tileGrid.fetchData(filterForm.getValuesAsCriteria());
}
});
/code
Three search items are created and fit together in the filterForm.
Using the form and entering just a part of a Common Name, will break
down the results with each letter I type.
Now comes the bad part:
I do not want the lifeSpanItem and statusItem any more. So I change
code
filterForm.setFields(commonNameItem, lifeSpanItem, statusItem);
/code
to
code
filterForm.setFields(commonNameItem);
/code
Now, trying to enter just a part of a Common Name will not break down
my results with each letter I type, but instead the behaviour is like
commonNameItem.setOperator(OperatorId.EQUALS)
So what I am saying is that the search works fine for searchItems
greater than just one TextField. My workaround therefore was to create
a HiddenItem as follows:
code
HiddenItem tagsItem = new HiddenItem(tags);
tagsItem.setOperator(OperatorId.EQUALS);
filterForm.setFields(commonNameItem, tagsItem);
/code
Now I think that this can't be right. Now am I missing something? Do I
have to use .setOperator on commonNameItem, if only commonNameItem is
present? If yes: Which OperatorId should I choose?
Thank you very much for your help,
Greets,
Jan

GWT + gears + eclipse, problem.
Hey, So I pulled the latest Galileo Eclipse release, and obtained the GWT plugin from dl.google. The demo helloServer app works without problem, and I have played around with things a bit and it seems fine with the hosted browser and so on. I wanted to start using the Gears code, and it seems that there is no plugin for this. Why is this the case? Oh well, so I pull the gears gwt stuff, and unpacked it, and dropped the jar files into the dropins folder on my eclipse installation. I create a project called test, and make sure it performs its helloServer ok. On the top of my Test.java file I then add import com.google.gwt.gears.client.Factory; import com.google.gwt.gears.client.database.Database; import com.google.gwt.gears.client.database.DatabaseException; import com.google.gwt.gears.client.database.ResultSet; because I will be using that later. I also add inherits name='com.google.gwt.gears.Gears'/ to my .gwt.xml file. I reload the live server thing and : Unable to find 'com/google/gwt/gears/Gears.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? And it hangs on the web page at the point where it should be making the TextField. I suppose I am not understanding how this dropins folder is meant to behave. Why is it looking for Gears.gwt.xml? There is no such file in the gears.gwt dist. Anyway, struggle onwards, right click on my project, go to Properties, into the Java Build Path, Add External Jars, and stick in the external jar file gwt-gears.jar into the project. So, now the IDE seems a little happier with things. I have a warning there saying I am not using the gwt.Gears stuff, and am including it for no reason but its happy that it knows what gwt gears is now. The live browser thing is a total basket case now. It no longer can even find test.html its giving me a 404 and masses of error messages. Ok so.. I run a compile, setting the it to debug level information, and it compiles happily. Note, I have not modified the code really at this point, its still the helloServer stuff I started off with. I just added jar file to the project, modified the xml file, and added a few includes. I'm running gwt-gears-1.2.1, gwt 1.7, my vm with which I run eclipse is java 6 from sun, in Eclipse version Galileo, on Ubuntu Jaunty, on a 64 bit machine, compiling against the 32bit libs as seemingly demanded by gwt.

Allow other domains to access a GWT application (running on Google App Engine)
Hi All, I would like to allow a particular set of other domains to access my GWT application (running on Google App Engine). Is this possible with GWT and how to do it? For example: Let's say I have the StockWatcher application from the tutorial running on http://stockwatcher.appspot.com. Part of the page StockWatcher.html are the lines link type=text/css rel=stylesheet href=StockWatcher.css ... script type=text/javascript language=javascript src=stockwatcher/ stockwatcher.nocache.js/script The application is run as http://stockwatcher.appspot.com/StockWatcher.html and everything works fine. Now let's say I want to also allow example.com to run my StockWatcher application. I tell them to make a copy of StockWatcher.html in their root directory and change the lines above to link type=text/css rel=stylesheet href=http:// stockwatcher.appspot.com/StockWatcher.css ... script type=text/javascript language=javascript src=http:// stockwatcher.appspot.com/stockwatcher/stockwatcher.nocache.js/ script The application is run as http://www.example.com/StockWatcher.html and, ideally, everything works fine. I tried a scenario similar to this but when I viewed http://www.example.com/StockWatcher.html I didn't see the StockWatcher application and no errors were reported. When I view the source of the page everything looks fine to me. My questions are: 1. Is this kind of application deployment possible in GWT? 2. If so, how would you go about doing it? I'm a developer new to GWT so I just need a kick in the right direction. 3. How would you get the example.com domain to check it against a whitelist of allowed domains in the GWT application?

GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7 -- how to add this or any other GWT library to projects?
Hi all, firstly the GWT / AppEngine plugin for Eclipse is sensational. To be able to deploy to production so easily is amazing. However a basic question -- how do you add other GWT libraries? I wanted to extend the template given by making a geolocation API call in gwt-gears I'm struggling to figure out where to add gwt-gears.jar. 1. I added it to my project's lib folder along with the other jars that were included in the default project but they are not presented through the GUI as available to add. 2. Adding them as 'external jars' solves the IDE syntax checking issues but then unsurprisingly crashes in hosted mode. I'm missing something basic I'm sure about how to add GWT libraries -- anyone have any suggestions? thanks!

Re: *.cache.html blocked by firewall - GWT team opinions please?
Hi Joe,
Please see reply inlined below.
Hmm. The gwt code to load the cache.html seems to be ignoring error
states:
line 315:
http://code.google.com/p/google-web-toolkit/source/browse/trunk/dev/core/src/com/google/gwt/core/linker/IFrameTemplate.js?r=5513
xhr.onreadystatechange = function() {
// 4 == DONE
if (xhr.readyState == 4) {
Shouldn't we add another check like:
if( xhr.status != 200 || xhr.status != 304 ) throwDocumentError();
This is probably a good thing to add in do you think?
You make a good point here. I think it would make sense to have a hook that
developers could implement here for such failure cases.
Would you mind filing an issue for this in the Issue Tracker? That way,
you'll automatically be notified of updates to the issue, and I can
assigning to someone on the team for further consideration.

I'm under the impression that the file's missing. In which case I'd
implement a watchdog timer in that routine. I'm guessing that Google

The file isn't missing - if I load up the cache.html file manually

the firewall and rationale (e.g. a high score).
After reviewing the source, the onerror function doesn't get called

Agreed.
Please try the cross-site linker.
I've never used it before - how will this help?
I'm guessing others haven't seen this since it's specific to these

firewalls? I have seen on this list a very difficult to reproduce
issue regarding RPC cargo getting truncated on the trip to the server.
But, obviously, that's after loading the script.
These are two separate customers (one university installation, one

I have seen the truncation issue before with a personal firewall

Re: Changing a Frame's contents when HTML widgets are clicked.
Divs of some description. Maybe as id'd divs in the html. This makes it possible to radically alter the layout without affecting functionality and allows designers to design and programmers to program. Even if the programmer is the designer, they can effect changes in the html and css without a recompile. Using divs (even if you are just adding flowpanels to other flowpanels) makes layout easier. Tables, as everyone knows, got a really bad press when used for layout (and VPs, HPs and DockPanels and the like are all table-based) and although there was a lot of rubbish talked, it is easier to get a semantically significant layout using divs (and that means text-readers - and search engines - can make more sense of it) DockPanels are something else again - they tempt programmers away from better structured code IMNSHO, creating too many classes at the same level. Which is probably fine while you are playing about and learning, but makes maintenance in real-life applications a right bugger. And most of these table-based panels *require* that you set heights and widths in the code unless you want all the TDs the same size. If you create three cells in a VP the only way to set the heights is in code - unless you shove other widgets in there and let them expand when you set the height of those widgets (but then if you decrease the size of the widgets, in some browsers the table won't shrink back). There are other consideration due to the way GWT works which means that in large apps you might get significant performance hits if, say, you are creating a lot of nested widgets. Using a widget has some overheads and if you don't need to use a widget then it's probably a good practice not to use a widget. Even if you need to do stuff dynamically in code, you can use the HTMLPanel and shove divs in that. A quick test showed that divs with ids in an HTMLPanel is 2.3 times faster than div elements with ids in another div element and 13 times faster than labels with ids in a verticalpanel. 10,000 took about 65ms, 150ms, and 850ms respectively (averaged over a number of tests). That was in Chrome. IE7 took between 35 and 40 seconds to put labels in a VP. Users start to notice delays like that. There may be quicker ways of coding it though, I just knocked 3 examples together, but it probably gives a good idea.

Hi
I want to refresh my webpage once after loading completely. I am using
this code for this
script language= JavaScript
function MyReload()
{
window.location.reload();
}
/SCRIPT
and calling
Body onLoad= MyReload() on body part of my html file
but this is not working
can anyone tell me where am i going wrong?
First problem is that you are asking a JavaScript question in a GWT group
:-)
Second problem is that your webpage will loop, endlessly loading and
reloading. This a pretty basic a mistake, so maybe it would be a good idea
to search for some JavaScript tutorials or sign up to a JavaScript
beginners' group.

Re: Refresh page on loading
Why do you want to reload the page as soon as it has just loaded?
Can't you just get it right the first time?
What do you want to happen the second time that didn't happen the first
time?

Serverside html generation with GWT Panels
Hi, I was wondering if anyone has looked into whether it is possible to replace the com.google.gwt.user.client.DOM implementation so that the same client side code could be used to generate static html on the server?

Is there a simple way to retrieve which index in a stack panel is active?
I am trying to modularize my code and was wondering if there was a simple way to determine which panel in the 'stack' is currently open. This would let me concentrate coding sections based on which panel is actually active. I hope this makes sense. Is there any method such as: public int getActiveIndex() ?
