Re: GWT - The response could not be deserialized
May be your returned object is null ?

I've tried it but i have the same problem.
Try wrapping you data objects in POJO's and not passing your data as raw
arrays and see if that helps.

Why does this cause error *The response could not be deserialized*?
p.s. I have tried to execute the project with app engine and without it,
but the problem is the same.

Re: gwt tomcat unix doesn't work
Hi, Can you post the error you get ? It would also be good to have the output of java -version which java Do you have any gcj installed ? Could you also post which distribution of linux you are using and which version ? Thank you. 2014-02-22 8:17 GMT+01:00 fedex shashankgris...@gmail.com: Hi everyone I am using tomcat version 6 in the unix server. When I try to run the sh version.sh file I get an error saying bad version. bin/bootstrap is not working i believe. I checked the jdk and jre version . They are compatible . I used commands java -version and javac -version to check the compatibility of java and compiler version. Recently I developed an application using GWT framework. When I deploy the application on the local tomcat server it wrks greats in the windows. I am using jdk 1.7 and jre7 in my local and verified on both tomcat version 6 7. The application worked great and have no issues. I used ANT script to package the application so to deploy on unix server. I used the same ANT script to build the package when I deployed on local tomcat. Can anyone suggest what exactly could have gone wrong. Based on the error I understand compiler is not compatible to java version. When I run the sh version.sh in unix it showed the JRE HOME variable as /usr folder.

Re: Compile Error after switching to 2.6 in first compile run
May be the algorithm to compute the compilation order has changed. Can you get the sequence of compilation in 2.5.1 and 2.6.0 so you can currently hard code the build sequence (and continue to use 2.6). Then you can post a bug report. 2014-02-19 9:04 GMT+01:00 Jan Thewes janthe...@gmail.com: I understand your points BUT one thing. If I compile my modules alone I don't get any compile error. So compiling every single module works. It has to do something with the order and caches. I just can't nail it down. We're running a real real big GWT application here. I'm close to go back to 2.5.1 because the compiles fail too often but not always... -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: New To GWT: Objects in composite object not aligned correctly
Hello,
May be try to use UIBinder and use HTMLPanel so you can have a good control
over the HTML that is generated. That is what I'm doing since Horizontal
and Vertical panels are built with table.
Using HTMLPanel with table gives you a cell per cell control.

Re: 2.4 RPC failure
Hi,
I have written an application and few month ago I got this error message :
com.google.gwt.user.client.rpc.StatusCodeException: 0
At last I found an explanation (for my case which might not worth for yours
but can give you ideas maybe).
I am developing my app on my laptop. So at home I have a network connection
(I use wireless connection). Then I suspend my laptop (that has at this
time an ip address and a network environment). When I am at my customer
site, I then resume my laptop. No wireless network and not cable network
available for people from outside but I didn't disable my previous network
configuration. Then I try to connect to my app with my browser. So the
browser is doing a call on a local machine with http://localhost:8080/blabla.
And there this message is raised !
After it happened a few times, I tried the following : disable wireless on
my laptop. Then the network configuration is changed. I just have a
127.0.0.1. And then I don't have anymore the error message.
Are your users on laptops or desktops ? Are they connected with cable or
wireless ? I don't know if this can match your case or not but may be the
problem is really related to their network connection (may be lan).
Hope this can give you some ideas to find out what your problem is.

Le 30 mars 2012 06:29, John Malpas jmal...@calflora.org a écrit :
I have several apps out there written in GWT 2.4
Over the last few months, users have started to complain
about seemingly random RPC failures, both reading and writing.
I have never yet experienced these errors from my own computer,
but there are enough users writing in about it that
it seems that there must be something going wrong -- not just
one user with a questionable internet connection.
The manifestation in the onFailure() method of an AsyncCallback
is usually
com.google.gwt.user.client.rpc.StatusCodeException: 0
I found one cooperative user who has been willing to beat on the
apps for me and send me results.He gets the errors with Firefox 8, IE 8,
and Chrome.When the RPC calls work, I see custom log messages in
the tomcat log. When the calls do not work, I see no evidence of any
activity
in either the tomcat log or the apache log, so it appears that the RPC
calls are not reaching the server.
This morning I changed one of the apps to include a symbol table,
and to print out a stack trace in a dialog when the failure happens, and
then
asked my precious user to try it. He sent back this stack trace,
copied from the dialog:
fail to write
CAUGHT com.google.gwt.user.client.rpc.StatusCodeException: 0
0 : Unknown.Em(StackTraceCreator.java:168)
1 : Unknown.Jl(StackTraceCreator.java:421)
2 : Unknown.RF(StatusCodeException.java:35)
3 : Unknown.bH(RequestCallbackAdapter.java:209)
4 : Unknown.bs(Request.java:287)
5 : Unknown.Bs(RequestBuilder.java:395)
6 : Unknown.anonymous(XMLHttpRequest.java:287)
7 : Unknown._l(Impl.java:168)
8 : Unknown.cm(Impl.java:213)
9 : Unknown.anonymous(Impl.java:57)
In broad strokes, I understand that the exception is
thrown because the browser is unable to do an XMLHttpRequest.
But more than that, why? I have looked up the line references
in the 2.4 source modules mentioned in the stack trace above,
but am still at a loss. The last one is this:
public final native void setOnReadyStateChange(ReadyStateChangeHandler
handler) /*-{
// The 'this' context is always supposed to point to the xhr object in
the
// onreadystatechange handler, but we reference it via closure to be
extra sure.
var _this = this;
this.onreadystatechange = $entry(function() {
287: handl...@com.google.gwt.xhr.client.ReadyStateChangeHandler
::onReadyStateChange(Lcom/google/gwt/xhr/client/XMLHttpRequest;)(_this);
});
}-*/;
Any suggestions would be greatly appreciated.

Re: Are handlers kept registered on PopupPanel when we call hide() on it ?
Thank you for your answer Thomas. I'll check this and will come back with other questions if I still don't understand :-) Boris 2012/2/6 Thomas Broyer t.bro...@gmail.com It looks like the issue is not really the PopupPanel but rather the widget(s) you add inside: if you reuse the same widget (either in a single PopupPanel that you hide/show, or within several PopupPanel-s during the lifetime of the application), then handlers won't be unregistered for you, just like for any other widget (the same goes for the CloseHandler attached to a PopupPanel: PopupPanel is a widget like any other –except you don't add it to a parent widget–, so handlers aren't unregistered automatically). If on the other hand you re-create everything from scratch every time, then you'll obviously have to register your handlers on the new instances. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Are handlers kept registered on PopupPanel when we call hide() on it ?
Hi, I was wondering how this is working. I made some code where I registered some event handlers on a PopupPanel so I can keep the data up to date. But when I call hide on this popup panel and recreate a new one, then handlers are registered 2 times and so events are handler 2 times. I was expecting another behavior : when the popup panel is hidden, I thought it was some kind of destroy. So I think that my strategy to rebuild a new PopupPanel is not good. Can you explain me how this should be designed please ? Many thanks in advance. Boris -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: The import cannot be resolved
Hi, Do you use those classes on the client side ? If it the case, it cannot work since you probably don't have any *.gwt.xml in your jar since this code cannot be translated to javascript.

Re: Error with Quartz
this place ( http://old.nabble.com/java.net---quartz-users-f13536.html ) is probably a better choice to post your question. Quartz is not related to GWT.

Re: MouseMove Events for CellTable / FlexTable
Hi,
I had found something like about this on the internet. The following code is
some hint on how to do this.
Boris
class Table extends FlexTable {
private String headerStyle = nostyle;
public Table(TableDataSource source, String stylePrefix) {
super();
this.setCellPadding(1);
this.setCellSpacing(0);
this.setWidth(100%);
this.setSource( source );
sinkEvents(Event.ONMOUSEOVER |
Event.ONMOUSEOUT);
}
//
==
public void onBrowserEvent(Event event) {
Element td = getEventTargetCell(event);
if (td == null) return;
Element tr = DOM.getParent(td);
switch (DOM.eventGetType(event)) {
case Event.ONMOUSEOVER: {
DOM.setStyleAttribute(tr, backgroundColor,
#ffce00);
onRowRollover(tr);
break;
}
case Event.ONMOUSEOUT: {
DOM.setStyleAttribute(tr,
backgroundColor,#ff);
break;
}
}
}
}
2011/5/12 matttai matt...@hotmail.com
Maybe attach the handler to the table and get the cell source when the
event is triggered.
Get the row index from the returned cell, remove all highlight style
from the table and add a highlight style to the row.
Not sure how efficient this would be though given the event would need
to be handled every time the cursor moves a pixel :)
Would be interested to hear other ideas. Perhaps experimenting with
mouseOver will yield better results though I am not whether mouseOver
events continuously fire if the cursor is left in the handling area. I
don't think they do but thats just a guess :P
Cheers,
Matt

Re: GWT Designer - full version
This page does not say that GWT Designer is a standalone product :-) Ok I found the page where Eve found the quote : http://code.google.com/webtoolkit/download.html If you click on the Download button for GWT Designer, you see that you are redirected to the eclipse download. So there is no standalone version as java editor that is not based on Eclipse (I'm pretty sure). So you have to use Eclipse with the plugin.

How can I move position of tab headers ?
Hello, I would like to display the tab header more on the right. Currently they are fixed on the left side with a css attribute left that is set to 0. The code that is generated by GWT is the following : div class=gwt-TabLayoutPanelTabs style=left: 0px; right: 0px; bottom: 0px; inside this, there is the code for tabs. /div I thought I could just get the element using code like this : Element element = (Element)nodeToUpdate; and then work on the style or remove it : element.removeAttribute(style); element.addClassName(CssResources.INSTANCE.commonCss().tabsHeader()); or element.getStyle().setLeft(150, Unix.PX) but unfortunately the style is not changed. I could changed some style that was not already set (for instance the color) but the one that are already set, I could not change them. I don't see other path currently. Does someone have an idea on how to do that ? Thank you ! Boris -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: MVP docs/tutorials/examples
Hi, Did you check this ? http://code.google.com/p/gwt-gae-book . It was announced few days ago by its writer and it seems to be an excellent work on this topic... Boris 2010/12/7 Andrey mino...@gmail.com Hello, We are going to use GWT 2.1 MVP in our projects. The problem is that there seems to be too little information about this framework. This doc is very poor: http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAndPlaces.html For example it tells nothing about how to use EventBus, where to place event handlers, how to register activities/controllers and so on. The HelloMVP example doesn't even contain any custom Event. Are there any additional docs/examples/tutorials concerning GWT 2.1 MVP with its Activities, Places, etc.?

Re: Calling java from external javascript
Thank you for your answer.
This part (calling js from java) is working fine. But my problem is calling
generated javascript from hand written javascript...
The export trick (see MyUtilityClass) does not seem to expose javamethods to
hand written javascript.
How can I call my java code from je javascript ? I have read the syntax in
the dev guide with @package.className::methodeName(parameters) but could not
make it work. I could neither make the export thing work...
I miss something but I cannot see where...
2010/10/6 Y2i yur...@gmail.com
I think Boris is correct by using $wnd. I also call my javascript
library functions from a native method through $wnd, as described
here:
http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html
Boris' example seems complicated. At the beginning I would simply
create a javascript function that calls alert:
function sayHello(name) {
alert(Hello from JavaScript, + name);
}
and a native method in my Entry Point class:
native void sayHelloInJava(String name) /*-{
$wnd.sayHello(name);
}-*/;
(this is exactly as shown in the reference above)
I use exactly the same approach, except instead of using HTML file I
place my JS library into a public folder and use script src='lib.js'/
in my module.
This technique is described here:
http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html#DevGuideModules
Once this worked I would move further.

Hi,
I'm currently trying to call a java method from a javascript that
lives
outside of the generated javascript from GWT.
What I want to do is the following :
make the gwt component communicates with a javascript component (in
both
ways).
I have to say that I don't know at all javascript..
The problem I encounter is the following :
* call to javascript method (generated by GWT) from my handwritten
javascript does not work : firebug says : $wnd does not exist.
I thought this variable was always existing in javascript but this
assumption is may be false.
I think it is quite basic (probably a problem of understanding in
javascript). I have read the following (this is where I found most of
the
code for doing the stuff) :
http://www.gwtapps.com/doc/html/com.google.gwt.doc.DeveloperGuide.Jav.
..
plus others (like
http://www.mail-archive.com/google-web-toolkit@googlegroups.com/msg38...)
but I'm stuck there.
Here the very basic code to test the feature :

panel.add(gwtButton);
RootPanel.get(sendButtonContainer).add(panel);
MyUtilityClass.exportStaticMethod();
final ClickHandler handler = new ClickHandler() {
public void onClick(ClickEvent event) {
jsButton.callSayHello(User);
}
};
gwtButton.addClickHandler(handler);
// Now I want to add javascript button that lives in a js
script...
jsButton = new JsButton();
panel.add(jsButton);
}
private class JsButton extends Widget {
public JsButton() {
DivElement element = Document.get().createDivElement();

Re: Calling java from external javascript
Thank you for your suggestions.
At last I found what was wrong (well I found a way to make it work :-) )
First, the call to the method in the onclick was not good. It was defining
an inline function instead of calling directly the variable that was
exported by the MyUtilityClass.
button.onclick = function() { $wnd.sayHello; };
needed to be fixed :
button.onclick = sayHello;
Second the documentation that I have read was probably slightly out of date.
Reading this
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html#calling(you
can see latest in the url ;-) ) showed a small difference in the
declaration of the new variable sayHello :
$wnd.computeLoanInterest =
$entry(@mypackage.MyUtilityClass::computeLoanInterest(IFI));
instead of
$wnd.computeLoanInterest =
@mypackage.MyUtilityClass::computeLoanInterest(IFI);
I have made those 2 changes and now it is working. I post the code in
case someone has the same problem.

Officially, you can refer to the following.
Quoted from
http://code.google.com/support/bin/answer.py?hl=enanswer=75695
How can I call one of my GWT Java methods from my application host
page?Share Comment Print
In order to accomplish this, you'll first need to create a JSNI method
that creates a JavaScript method that in turn makes the call to your
Java method. In your GWT application's onModuleLoad(), you would call
that JSNI method so that the JavaScript method is defined. From your
application host page you would then call the created JavaScript
method.
Confused yet? It's actually quite simple.
The code snippet below shows an example of this (courtesy of Robert
Hanson):
private native void initPlaylistJS (PlaylistTable pl) /*-{
$wnd.addClipToPlaylist = function (clipId, clipTitle) {
p...@com.foo.bar.client.playlisttable::addClip(Ljava/lang/
String;Ljava/lang/String;)(clipId, clipTitle);
};
}-*/;
In this example, you would need to make a call to initPlaylistJS(pl)
in your GWT module's onModuleLoad(). Once your GWT application loads,
the JavaScript method is defined and is callable from outside of the
GWT application.

Re: Calling java from external javascript
Sorry for the javascript : there is a mistake : variable name is not
buttonnode but button at return step of the method...
Anyway the problem still stands ;-)

Hi,
I'm currently trying to call a java method from a javascript that lives
outside of the generated javascript from GWT.
What I want to do is the following :
make the gwt component communicates with a javascript component (in both
ways).
I have to say that I don't know at all javascript..
The problem I encounter is the following :
* call to javascript method (generated by GWT) from my handwritten
javascript does not work : firebug says : $wnd does not exist.
I thought this variable was always existing in javascript but this
assumption is may be false.
I think it is quite basic (probably a problem of understanding in
javascript). I have read the following (this is where I found most of the
code for doing the stuff) :
http://www.gwtapps.com/doc/html/com.google.gwt.doc.DeveloperGuide.JavaScriptNativeInterface.JavaFromJavaScript.html
plus others (like
http://www.mail-archive.com/google-web-toolkit@googlegroups.com/msg38714.html)
but I'm stuck there.
Here the very basic code to test the feature :

Re: Problem with GWT Google-Maps-API 1.1 and IE 6
Hi Eric, Thank you for the link. I have just installed it and tested out. Unfortunately, this does not really change the thing. It is a little bit faster but still unusable. I've installed (just to check the difference) Google Chrome under Windows and the application runs fine. But with Chrome embedded in IE6, I don't have the same performances at all. Boris 2010/10/1 Eric Ayers zun...@google.com I'm going to go ahead and steer you away from there because all the gwt-maps library is doing is translating your GWT calls into javascript calls to the Maps API. If you are willing to install a plugin, try the chrome frame plugin for IE6. http://code.google.com/chrome/chromeframe/ On Fri, Oct 1, 2010 at 8:54 AM, David Chandler (Google) drfibona...@google.com wrote: Hi Boris, You might also try posting your question here: http://groups.google.com/group/gwt-google-apis /dmc David Chandler Developer Programs Engineer, Google Web Toolkit On Sep 30, 3:26 am, Boris Lenzinger boris.lenzin...@gmail.com wrote: Hi everybody, I'm currently facing a blocking problem when using GWT google map api (version 1.1.0) with IE 6.

This A-square is composed of smaller squares (let's denote the B-square). There are around around 180 B-squares per map. They are also clickable. When you click on a B-square, its color changes according to the context. It is also added to a list of selected squares (or removed if the click is for unselecting it). I got it working but it is very very slow. It is completely unusable in fact.

First CPU usage is raising to 50% while applying color. It seems that the A-square and B-square (and in fact all polygons) are displayed using SVG polygons. I have seen this with Firebug when selecting a B-Square. But IE does not have native support for SVG and I think the problem is that : no native support for SVG. I have tried to install Abode SVG plugin but it didn't change anything. I then tried the library http://code.google.com/p/sgweb/but it didn't work neither. So I really don't know how to solve this.
