Re: Need to display a disabled checkbox without changing the appearance

Re: A native GWT chart library?
Hi, Tatami http://code.google.com/p/tatami/ project wraps the dojo framework in GWT... it's open source. Regards, Hasan...

Ben, I looked at the links you gave me, a lot of interesting things but no client-site library that fits my need. For what it's worth, I too would really like a client-side library - mainly so that I can do lots of quick, small updates without much latency. The quality just wasn't adequate for the client-side libraries that I tried, so I switched back to a server-side library. In my case, so far there has been no noticeable increase in latency: you may wish to reconsider your need for a client-side solution, and at least try it with an easy server-side solution (aka Google Chart API or Eastwood) and see what your results are. Maybe you've already tried this, or have other good reasons for a client-side solution. So I think I'm gonna end up doing a wrapper for dojo chart. Sounds like a great project, and one that would be useful to many (including me). If you make progress on this, would you consider establishing a Google Code project? Best of luck, Ben.

Re: Strange window popup with Anchor widget in 1.6.4
The anchor widget is just a regular a href= tag so if you use that
constructor, clicking on it will open a new browser window. To get an
anchor that doesn't do that use the constructor
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/Anchor.html#Anchor(java.lang.String,%20boolean,%20java.lang.String)
with # as the href.

Re: serialization to history - bad idea?
I'm not sure I understand what you're trying to do, but it seems to me that you want to use those classes client-side so you might want to look at the JRE emulation reference: http://code.google.com/webtoolkit/doc/1.6/RefJreEmulation.html You'll realize that it's not possible.

Re: OnMouseOver and OnMouseOut on FlexTable
http://code.google.com/webtoolkit/doc/1.6/ReleaseNotes_1_6.html#NewFeatures Here's an interesting excerpt from that link: For users who create their own Widgets, you no longer need to manage listeners manually. Every widget has a HandlerManager that manages all of its handlers. For native events, such as ClickEvent, just call addDomHandler() from within your code to register a handler and sink the associated event on the Widget. When the native event is detected, the handler will automatically be called. For logical events, such as SelectionEvent, call addHandler() and fire the event manually using the fireEvent() method. You can see examples of EventHandler usage in many of the updated GWT widgets and samples, or in new projects created with the new webAppCreator tool.

i18n in client/server application
Hi, I am a client/server application with a strict separation of client and server code, which means that server code (like domain objects) are allowed to be used by the client, but no client code might be used be the server code (of course). Now I want to externalize all of my strings (error messages, labels etc.). Some of them (like labels) are in the gui code and I can use the gwt i18n concept (Constants interface) for it, but others are in the domain objects (like the default name of some objects). Therefor I would normally use the standard java resource bundle approach, but as the domain objects are also used in the client this isn't possible. Unfortunately I cannot use the gwt approach either as I would have to use client code in the server part then.

Re: i18n in client/server application
Explain again why the name of objects can't be internalized using constants on the client side?

Not sure what your question is. Are you trying to format for display? Are you trying to parse input? Trying to determine something else? Formatting parsing already done for you: http://google-web-toolkit.googlecode.com/svn/javadoc/1.4/com/google/gwt/i18n/client/DateTimeFormat.html A hack (unless there's no better way) would be to use DateTimeFormat to format a date so it displays a known time like year 0, month 1, day of month 1, hour 23, minute 0, second 0. Then search for the number 23 in the formatted string - if it's there, you're on military time - otherwise AM/PM. However, this obviously has downsides because it makes assumptions about how the locale formats the time (in particular assumes arabic numbers for time format).

Re: How to know Time Format of System time at client side
Sorry but I'm still not understanding exactly what you're trying to do. I got the part where you're saying that you want to store a timestamp in a database. But is it the server-side time or client-side time ? Either way, you shouldn't need to format dates to do that, just pass the java.util.Date object in your RPCs and then instantiate your timestamp from the date object before storing it in the database. What are you're storing those timestamps for ? Because depending on that, you might not want to trust the dates handed to you by your clients and instead use the date of the actions you want to timestamp in the server side of your code.

Re: How to know Time Format of System time at client side
but if client side time is in 12hr format then also I am getting 24hr
format time.
What do you mean by that ? Could you be more clear ? I want to help
you but I need to know what it is that you're not understanding from
what I told you.
Maybe paste some code snippets that'll show me how you're tackling
this problem because time formats have nothing to do with storing a
timestamp.
Normally this is what you should do:
//client-side: instantiate a date and send it to server to be stored
Date executionDate = new Date();
SomeRPCAsyncInterface.storeDate(executionDate, someCallback);
//server-side:
public void storeDate(Date executionDate){
Timestamp executionTimestamp = new Timestamp(executionDate.getTime
());
//the code to persist the timestamp, (JDBC, hibernate, or whatever
you use to store things in your database)
}
So there it is, no need to use formatters anywhere.
I hope it's clearer now. If it isn't you should familiarize yourself
with the way the Date object works and its API
Good luck,
Salvador

I am sending client side date as follows:
Date executionDate = new java.uti.Date();
and storing id database same as u told like:
Timestamp executionTimestamp = new Timestamp(executionDate.getTime
());
But my problem is that I want to store the time in the format same as
client side.
Means if client side time is 03:45PM then it should save 03:45 and not
15:45.
And if client side time is 15:45 then it should save 15:45.
But I am getting time as 15:45 if my system time is 03:45PM.

Re: i18n in client/server application
Explain again why the name of objects can't be internalized using constants on the client side? Maybe that was a bad example. It's easier to explain with exceptions (defined in my application). Exceptions have an errortext that should be internationalized as well. As exceptions are thrown at the server and catch on the client, they are used in all architectural layers. So I cannot use java.util.ResourceBundle as GWT would throw an error (No source code is available for type java.util.ResourceBundle). On the other hand I cannot use the GWT constants interface either as I must not use client code (or client libs) on the server where the exceptions are defined. Anyways, the general solution would be to set the internationalized string using java resource bundles in the server code prior to sending the objects over the wire to the client code. Please explain that to me. How should I set the string? Do you think of some kind of client class that sets all the strings in all server classes that has to be internationalized? That would look crude to me. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

gwt incubator grid grouping
I very much like the feature of grouping in Grids that smartgwt can offer.

Re: Creating GWT application
Glad that everything is working for you. As an FYI, if you have a proxy server that you can use to hit the Eclipse update site, you can configure Eclipse to use it when performing an update or an installation. In Eclipse 3.3, go to Windows - Preferences - Network Connections (or Eclipse - Preferences - Network Connections, if on the Mac). We'll definitely add some more documentation to help out people that are suffering with proxy issues.

Re: How to know Time Format of System time at client side
But why do you want to store it in the format of the client ? How is
the format relevant ? What are you trying to do with that data ? It's
not really a good practice to store dates in inconsistent formats in a
database, I'm pretty sure you're subverting the utilization of date
formatters to accomplish that should be easier to do differently.
Really, don't do that.
And one more question, have you read the javadoc for DateTimeFormat ?
I have the impression you didn't so here's a useful link:

No you don't. You decide what format you want to display and

If you want to display a date in the 24h format, you have to do:
Date myDate = new Date();
String formattedDate = DateTimeFormat.getFormat(dd/MM/

Re: Strange window popup with Anchor widget in 1.6.4
Thanks Salvador, this seems to have worked.
What is confusing is the constructor I used has in the javadoc:
Creates an anchor for scripting. The anchor's href is set to
javascript:, based on the expectation that listeners will be added to
the anchor.
This seems to imply what I was trying to do, but maybe href set to
javascript: doesn't work. Is this a bug?

Re: GWT Mail sample using Spring Dreamsource ORM
I am developing this ORM for seven years. It has been used in three major applications for over three years. Please check it at www.leeonsoft.com for more information. The ORM solves the following problems: 1. Whatever you codes happens in database. No merge 2. No detached enhanced object. 3. No lazy loading. Just eager loading because you can expect whatever you want during coding. 4. Easy to learn and use because it just mirrors SQL statements. 5. High performance compared to Hibernate 6. High productivity. 7. It can be used in GWT and any other frameworks without third party libraries. 8. It provides most demanding features in a small library. 9. It provides JPA 2.0 query feature in a smart way. 10. Eclipse plugin to generate ORM code will be available by the end of this month. You can find Spring and GWT examples from http://www.leeonsoft.com Any feedback is appreciated.

Re: How to know Time Format of System time at client side
Priya, you can't do what you are asking.
If you are storing a datestamp in a database then you will probably be
storing the number of milliseconds since 01 Jan 1970. Whatever format you
pass to the database, if it can understand it, it will convert it to that.
In a lot of cases, it will guess wrong, -mm-dd HH:mm:ss is usually safe.
If you are storing it as text, then that is different. In that case, I think
that the only way to get the user's preference is to ask them.

GWT 1.6 TreeListener onTreeItemSelected

Re: GWT 1.6 TreeListener onTreeItemSelected
From a quick glance at the javadoc (http://google-web- toolkit.googlecode.com/svn/javadoc/1.6/index.html) you can get what type of handlers you can add to a Tree. You're looking for SelectionHandler: http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/Tree.html#addSelectionHandler(com.google.gwt.event.logical.shared.SelectionHandler) Some code examples: http://code.google.com/webtoolkit/doc/1.6/DevGuideUserInterface.html#DevGuideEventsAndHandlers http://code.google.com/webtoolkit/tutorials/1.6/manageevents.html On Apr 22, 5:58 pm, Micky micky.johns...@gmail.com wrote: In previous versions of GWT one could add a tree listener to a tree and use onTreeItemSelected to handle when a tree item was selected by the user.

Re: i18n in client/server application
Just use the regular java way to look up the exception message throw it. Don't understand your problem. On Wed, Apr 22, 2009 at 9:45 AM, olel lauri...@engram.de wrote: Explain again why the name of objects can't be internalized using constants on the client side? Maybe that was a bad example. It's easier to explain with exceptions (defined in my application). Exceptions have an errortext that should be internationalized as well. As exceptions are thrown at the server and catch on the client, they are used in all architectural layers. So I cannot use java.util.ResourceBundle as GWT would throw an error (No source code is available for type java.util.ResourceBundle). On the other hand I cannot use the GWT constants interface either as I must not use client code (or client libs) on the server where the exceptions are defined. Anyways, the general solution would be to set the internationalized string using java resource bundles in the server code prior to sending the objects over the wire to the client code. Please explain that to me. How should I set the string? Do you think of some kind of client class that sets all the strings in all server classes that has to be internationalized? That would look crude to me. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

JQuery Object in GWT
I am still having trouble getting gwt and Jquery to work well with
each other. I have a javascript I am trying to call natively:
public static native void callSomeJavaScript(){
divs = $wnd.$(div);
console.log(divs);
}
Now in FireBug divs it shows up as a Jquery Object.
Outside of GWT it shows up as a list of elements (essentially).
Where I get problems is when trying to call certain functions such as
divs.hasClass(foo);
in GWT it complains that this function does not exist.
The other problem is this code is actually in another file and is
going to be used by other non GWT pages:
public static native void callSomeJavaScript(){
div = $wnd.$(div#bar);
foo = new $wnd.FooClass($wnd.$(div.foo), {text: div.clone().find
('.duplicate').empty().end().html()});
}
and in FooClass:
window.FooClass = function(node,options){
function initialize(node) {
a = $(node).eq(0);
a.hasClass(foo-class);
}
initialize();
}
It breaks on a.hasClass

Re: java.lang.StackOverflowError with GWT
I also had this problem but worked around it by setting the localWorkers parameter to com.google.gwt.dev.Compiler to at least the number of permutations I'm compiling. Why this should work I have no idea, but it does, at least for me. I'm only building 5 permutations so this is a reasonable solution, and gives a faster compile.

I've run into quite a strange issue serializing dates from the browser to the server. When I enter the following dates in the browser I receive for some dates the wrong value at the server side (using date pattern dd-MM- ): 1-1-1968 - Mon Jan 01 00:00:00 CET 1968 - correct 1-3-1968 - Fri Mar 01 00:00:00 CET 1968 - correct 1-4-1968 - Sun Mar 31 23:00:00 CET 1968 - wrong 4-4-1968 - Wed Apr 03 23:00:00 CET 1968 - wrong 1-4-1999 - Thu Apr 01 00:00:00 CEST 1999 - correct Note that in April 1968 there is a 1 day difference.

Reading xml

Click event fires on double-click
Hello:
I'm working on a ListBox subclass, called DoubleClickAwareListBox. On
double-click events, the click event fires twice, no matter if I'm
using a ClickListener or overriding onBrowserEvent(Event event) like
below:
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
int type = DOM.eventGetType(event);
if (type == event.ONDBLCLICK) {
GWT.log(SDD, null);
}
else if (type == event.ONCLICK) {
GWT.log(, null);
}
}
I want double-click and click to be two distinct events. Is it
possible to prevent this behavior?
Thanks

automatically update table with subtotals and totals
I have a single FlexTable that is broken down into sections ( for lack of a better term ) and each section has a total and then the entire table is totaled at the bottom (see below). Currently I don't update the table dynamically because I haven't found an efficient ( or easy ) way to do it ( i.e. at this point I just refresh the browser and rebuild the entire site). However, I am at least considering refreshing what is drawn in place and re-totaling as a starting point ... In other words, at least initially, I won't try to add or remove or change the positions other than just updating the market price and its corresponding effect on the position, section and table totals. I have started to just code a manual process of going through the FlexTable and finding the sections and then the stock symbol and then for each entry grabbing the latest price and such ...

IE Find Dialog produces an error in our GWT 1.5 app
Hi everyone, This is something unusual with Internet Explorer that I haven't seen before, and haven't found any hits about in my online search. I'm hoping someone has encountered this before... We are using GWT 1.5 for our doctor search: https://www.healthnet.com/portal/providerSearch.do In IE 6 or 7, at any point in time during this search, do a File -- Find or Ctrl+F. Type anything in the Find text box and click next or hit enter A dialog box pops up with an error. Depending on which version of IE you are using it will either be Error 122 or 125. An error has occurred in this dialog. Error: 125 'location' is null or not an object I tried this in the hosted browser and it behaves exactly the same, but there are no JS errors / exceptions in the hosted browser console. How strange that this is an error with the actual dialog box? Thoughts? Guesses?

GWT vs. Facelets/JSF/RichFaces
Hello GWT'ers, I have been looking into the basics of GWT for a few weeks now but haven't touched much code. The company I work for has existing web applications which are pretty big and use J2EE technologies (a combination of JSF / Facelets / Richfaces / Javascript on the front end, and backing beans / session beans / J2EE services on the back end). The websites use google maps heavily, and are very important to our company. Since we are using so many different technologies in the presentation tier (and in order to work on the code, having to jump between them), I have been curious if GWT can simplify things for us. I have a few questions though. Are there any big pitfalls to using GWT? Any problems that are difficult to get around? Can the UI be customized as much as you can customize a HTML page? (As far as changing colors, sizes of things, looking and acting similar to traditional websites, etc...).

I would like to know how to set x and y when I firing an event on

int x = new value;
int y = new value;

and y to modify its
original values ?

SWT seems to think I'm running on Linux and not a Mac ???
Hi, I've been going back and forth with Instantiations tech support over their GET Designer Eclipse plugin. When I try and execute a GWT application in Eclipse that I built with the Designer, I get an Exception immediately. The error is: Exception in thread main java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3062 in java.library.path. Instantiation's support says that for some reason, GWT's SWT really does think I'm running on Linux. I'm using gwt-mac-1.5.3 (the Designer on the Mac doesn't yet support 1.6.4 according to Instantiation support) and I also have the current Google plugin from Google's Eclipse update site installed.

Re: Multiple Modules in 1 war Sharing RPC
Hi Chris, I'm glad someone else is asking this. I asked some similar questions: where are the controls for naming and locating of important GWT artifacts (RPC connections, directories for HTML files, etc) in GWT 1.6, and reference documentation? See:Issue 3547. http://code.google.com/p/google-web-toolkit/issues/list We are building an application that makes 20 separete calls on as many as 13 GWT modules in the same application (one of the modules is completely reused 7 times) in GWT 1.5.3. Several modules also share the same RPC service.I am not seeing a lot of documentation to begin with on how you deal with multiple modules and sharing of modules with multiple HTML files, or of shared services even for GWT 1.5. However, GWT 1.6 moves a number of objects around, including the RPC calls. - In GWT 1.6, RPCs now use (a lower-case version of) the name of the module prepended to the service name. - This does not match up with the service name annotation in the Service class. So, where is this controlled and what determines it? For most people converting to 1.6, this change requires a changes in web.xml. For some it may require changes in Spring- Servlet.xml if they are using spring-loaded services (there is more information about this. See Issue 3547 for reference info). - The default location of HTML files is now the root level instead of in package.package.modulepackage/public and the URI has been changed so it is no longer package.package.package.ModuleName/HtmlName.html. However, how is this controlled? In general I would like to see more documentation on multi-module projects and server-oriented documentation. The GWT in Practice book has one example with two modules and uses GWT 1.5. Somewhere there needs to be some document that discusses the recommended relationships (1 to 1/many) between modules, HTML files, and services.

So my web.xml needs to look like: /moduleA/login /moduleB/login Is there a way to havemodulesin the samewarshare web.xml definitions/servlets as we did in 1.5?

Re: GWT vs. Facelets/JSF/RichFaces
It is pretty easy to switch to GWT when you have JEE background. I modified GWT mail sample to use Dreamsource ORM to connect to database. You can view this sample from http://www.leeonsoft.com/mail/Mail.html. Dreamsource is designed to target GWT applications. Basically, all GWT widgets are HTML. You can easily figure out how to customize them in debug mode of Eclipse.

Enclosed: POM fragment that gets Maven to play nice with GWT 1.6.4
After a day or so playing around I have made a Maven pom.xml that
respects the directory structure output by the webappCreator tool.
Here are the relevant bits. Again, for veteran Maven users, rather
than try to make the GWT Eclipse Plugin respect a tried-and-true maven
layout, which I've read on this group is kind of tough if not
impossible, I went the other way around. That means that you will NOT
see a src/main/java directory, and the war source directory will also
be used as the target (that's how the GWT tools do it).
Another way to put it is that I followed the advice of the plugin
authors who said when in doubt try to make your custom build tooling
do what the base ant build.xml does.
Lastly, this POM fragment uses the Codehaus gwt-maven-plugin, so if
you run:
mvn package
...you'll get your war file in the good old target directory (where it
should be, of course) and your in-place war in the war directory.
This should allow Eclipse folks to work normally, as well as hosted
mode.
I hope this helps someone; it took WAY too long to do this.
As of today, April 22, the only known issue is that the gwt-maven-
plugin will see your module twice (you can configure it to only look
for specific modules and can avoid this; I didn't). That means at the
moment that at package time you'll run the resource-hoggy GWT compiler
twice. :-( I think that bug will probably be fixed very soon, so I
didn't choose to work around it in this pom fragment.

Re: Making a call to more than one server
The Same Origin Policy does not apply to making requests to another domain. It applies to manipulating the properties of another document from a different domain.

what optimizations are needed to improve performance
His, I am seeing above expected performance on my application that displays a table (17 x 17 Flextable, using only GWT widgets) of rows that should be updated (Timer, RPC) at 1 second intervals. While the application targets IE 6 which run somewhat slowly (updates tend to be perfomed about 3 times slower), for sake of fairness I must attest superior performance in Firefox 3. Are there common optimizations that help improve speed besides what was recently covered in thread http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/c5b8141e70a221ec/5ed79b1444d526b9?lnk=gstq=efficiency+of+my+gwt+application#5ed79b1444d526b9 I have already made sure: - to apply styles only when really needed to avoid browser redraws - to use table: fixed to improve table rendering (http:// groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/ 4e7ae69a917236a8/f3fa66ce621e9cb5?lnk=gstq=layout%3A +fixed#f3fa66ce621e9cb5) - to use Timer#schedule(1000) instead of timer#scheduleRepeating(1000) to process updates one at a time, as resources free up What else could one think of? Also, facing some memory leak issues (in IE 6) as there are a lot of objects (Labels, Composites) being created for each row update coming from server. It seems to be solved by reloading page every 30 minutes, but I am wondering if there is a better way to free up browser memory automatically and at certain intervals? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Request after request.
Hi.
I'm trying to implement chat on my GWT app. So client has getEvents()
function implemented like this :
public void getEvents( )
{
networkSvc.getEvents(
new AsyncCallback ArrayListEvent ()
{
public void onSuccess( ArrayList Event
events )
{
handleEvents( events );
networkSvc.getEvents( this );
}
public void onFailure( Throwable caught )
{
System.out.println(eventListner +
caught );
}
}
);
}
This func in an endless loop with the server .
at the server side getEvents goes to sleep for 30 sec or till events
approaching.
The second function is sendEvent() function.
As i see, i can't send an event to server while the server processing
the previos request.
I mean it looks like the sendEvent() waits till the getEvents() gets
the response,
and just after that it sends its own request.

Re: what optimizations are needed to improve performance

Also, facing some memory leak issues (in IE 6) as there are a lot of objects (Labels, Composites) being created for each row update coming from server. It seems to be solved by reloading page every 30 minutes, but I am wondering if there is a better way to free up browser memory automatically and at certain intervals? If the structure of your table doesn't change, then pre-create those labels composites simply change the data being displayed. Otherwise, at least for IE, innerHTML is significantly faster (although you lose the ability to do widgets event handling gets more complicated) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT vs. Facelets/JSF/RichFaces
GWT is essentially a fancy Javascript framework. So in your question replace GWT w/ Javascript you'll have the answer. On Wed, Apr 22, 2009 at 2:29 PM, Jon Onstott jononst...@gmail.com wrote: Hello GWT'ers, I have been looking into the basics of GWT for a few weeks now but haven't touched much code. The company I work for has existing web applications which are pretty big and use J2EE technologies (a combination of JSF / Facelets / Richfaces / Javascript on the front end, and backing beans / session beans / J2EE services on the back end). The websites use google maps heavily, and are very important to our company. Since we are using so many different technologies in the presentation tier (and in order to work on the code, having to jump between them), I have been curious if GWT can simplify things for us. I have a few questions though. Are there any big pitfalls to using GWT? Any problems that are difficult to get around? Can the UI be customized as much as you can customize a HTML page? (As far as changing colors, sizes of things, looking and acting similar to traditional websites, etc...).

Re: Request after request.
Most browsers only support 2 outstanding AJAX events - that may be what you
are running into. Without knowing what other calls you make, I cannot make
a recommendation.
One thing that does come to mind is that I hope you only call getEvents once
on startup.

Hi.
I'm trying to implement chat on my GWT app. So client has getEvents()
function implemented like this :
public void getEvents( )
{
networkSvc.getEvents(
new AsyncCallback ArrayListEvent ()
{
public void onSuccess( ArrayList Event
events )
{
handleEvents( events );
networkSvc.getEvents( this );
}
public void onFailure( Throwable caught )
{
System.out.println(eventListner +
caught );
}
}
);
}
This func in an endless loop with the server .
at the server side getEvents goes to sleep for 30 sec or till events
approaching.
The second function is sendEvent() function.
As i see, i can't send an event to server while the server processing
the previos request.
I mean it looks like the sendEvent() waits till the getEvents() gets
the response,
and just after that it sends its own request.
Is that right, or there is some bug in my algorithm ?

Re: GWT 1.6, Google App Engine, and java.awt.image.*
GWT doesn't support java.awt.anything. You have to use the GWT Imagehttp://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/Image.htmlclass. GWT != Java has nothing to do with App Engine (other than you can host your GWT project on App Engine). To disable App Engine, I believe there's a setting the in the project properties (never used GEP, so I can't help you with more specifics).

Right now, I would like to get my application of a few thousand lines of code working under GWT 1.6. It works great under GWT 1.5. I took your advice and told Eclipse to not use App Engine, and Eclipse did stop complaining. I hope this works in the end. Thanks, Danny On Apr 22, 8:15 pm, Ben FS ben.su...@gmail.com wrote: Client-side: GWT lets you use Java language, but only a sub-set of the J2SE library, supplemented by a variety of GWT-specific UI classes. Server-side: You can use whatever you want, including Java. If you wish to use Java (J2EE) on the server, you can - and then the GWT RPC mechanism can be handy. If you wish to deploy to GAE, there are some restrictions - for example, no file access - but the main difference with GAE is how you store data persistently.

I understand that Google is working on App Engine for java and has probably not yet implemented image. How can I proceed, since the new eclipse plugins insist on App Engine, even when I remove the App Engine SDK. Any suggestions?

JS error in IE
I am getting a JS error/warning pop-up box in IE (not Firefox), which
says:
Line 1327
Char 16
Error: 'Bzc.j.k' is null or not an object
Code: 0
URL: my site's URL
This error/warning does not break anything, and if clicked away, the
site works just fine. However, it happens on a page which the users
first come to, and so creates a bad impression. I opened up the
compiled cache.html file mentioned in the error, and used the line/
char coords to locate the problem. There is a line in there which
says:
function wyc(){b6b((nzc(),Bzc).j.k,true)}
This, I believe, is what the IE pop-up is referring to. However, this
code isn't exactly readable, so I have no idea what is wrong with it,
or in fact, what it does.
I also ran the page through several JS debuggers, but that did not
help at all. Do you guys have any ideas as to how I should proceed?
Any input would be appreciated.

GWT RPC for inter-server communication?
Hello, I actually rather like the GWT RPC API and was hoping to use it for more than client/server communication - in fact, I want to use it for server/server communication. Here is some example servlet code: http://gist.github.com/100232 The callService() method would be designed to hit a different server, of course. Has anyone else used GWT RPC in this way? Will it even work? (I can't test this code right now because the Google App Engine plugin on the Mac doesn't seem to run hosted mode correctly). BTW the attributes of GWT RPC that I like is the JSON transport, and the asynchronous API. I also like the idea of dealing with communications in a more homogeneous way. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hi people,
I used mouseListeners.fireMouseMove(this,x,y) on onBrowserEvent

I'll appreciate any help.
Have a look at com.google.gwt.dom.client.Document.createMouseMoveEvent
and com.google.gwt.event.client.DomEvent.fireNativeEvent, I believe
they'll be helpful.
But may I ask why (you think) you need such a coordinate transform?

var that = this;
$wnd.__gwt_login = function() {

or change the method's signature:

and call it like that:

That's JSNI 101 ;-)

Re: single row in PagingScrollTable does not have proper height in IE7
This sounds like a rendering bug with the PagingScrollTable. All I can suggest to do is a) check out the latest incubator and see if the issue is still there b) if it is, file an issue with the incubator issue tracker.

When I have only a single row in the table, the table height shrinks such that the row is no longer visible. If I add more rows, everything is properly sized. It seems as if maybe the height of the horizontal scrollbar is not being taken into account, or some other off by one error is happening. My current workaround is to add a stylename with an explicit height: 30px to the row using RowFormatter. This is kind of a hack, as the height of my rows varies with the data contained.
