Re: GWT application that can run on the server and client?

[Saeed Zarinfam]

Hi
This is possible. You can do it with a SWT Browser widget and a
embedded web server (tomcat or jetty) and war folder of your GWT
application.

[Šobis]

Hello,

can you please help me with this issue, because I'm slowly losing my
mind.

I have GWT project, where in MyProject.gwt.xml I have

 and


In MyProject.html I have:


but for TabPanel I always get style from Standard.css. What am I doing
wrong?

In MyProject.css I have

.gwt-TabBarItem{
.
}
.gwt-TabBarItem-selected{
.}


but in FF I get style from standard.css where class is



I tried !imporatant thing but is not working.

I added style tabRazred in code (for TabPabel.tabBar) and in CSS I did
like this

.tabRazred-TabBarItem{
...
}

But I'ts not working.

So if anybody had similar problem or know how to solve this, please

Re: How to deploy GWT application in tomcat

[Tamás Gömbös]

I have copied all the required jars to WEB-INF. And my servlets work
properly because they send back data when I call them explicitly. But it
seems that the client doesn't send any request to the server when I start
the application with .html. And again: in hosted mode
everything's fine.

I forgot to mention that when I start the application in hosted mode and
start it in a browser with the "Compile/Browse" button it also works
properly.

Re: Standard.css always override my MyProject.css

[philippe]

Hi Sobis,

Try this:

In your Application.gwt.xml, add this line after standard theme
definition:


I think you must use !important, check if it's well write.

Delete the style definition in your html. On my project, it's work.

regards,
Philippe

Re: Too much is happening (the events are crowding the bus)?

[mariyan nenchev]

Hi,
I am interested in this gwt architecture too. I did have a look at the video
and a hello world application implemented with this architecture, and really
i think that this is too much code to write. I also looked at the apache
hupa project, that is using the same architecture. And they did a generic
events for add,edit, delete, fetch, so you only will need to add new events
for your custom cases, which is not so bad.
I as we speak for this, does any one else know other open source projects
written with this architecture. I want to have a look at them, since a mail
client (hupa) is not the best to learn from.

Regards.

As noted in the release notes, "The -portHosted Development Mode flag
has been renamed to -codeServerPort"; and as also noted (well, a bit
implicit I concede), you need to update your Eclipse plug-in by
unzipping the RC2 version (just as you did with the RC1) as there's no
update site for them. (unzip the RC2 *above* the RC1, as it seems the
RC2 distro isn't "complete")

Client-side object storage

[Aekold]

Hi All!

I want to save some object (panel for example) to use it later. On the
server side I can use request, session or even some singleton or
static map. But what can I do on the client? Strings or other
primitives I can save into Cookies, but what to do with panels?

[GWT-SL] setServiceEntryPoint()

[Jacek Zebrowski]

Hi !

I did all according to docu 
(http://gwt-widget.sourceforge.net/?q=node/51#GWTHandler)- my service is 
present under myapp.url/handler/testrpc.
but GWT expects me to supply : setServiceEntryPoint()...

When i set it to GWT.getModuleBaseURL()
it submits the service to :

localhost:8080/myapp/myapp which is obviously wrong... how should i 
proceed ?

Use GWT.getHostPageBaseURL() instead?

Re: Full GWT Website with MS SQL Server 2008

[Christian Goudreau]

Nice work.

Two things I have to say from my fast visit, but that's two thing you
probaly already know.

1- History Management
2- Your animation. I have done something more smooth than that, so I assume
that it's an incomplete work ? We see the desapearance and it's not smooth
at all.

Really nice work again !

Re: Google Web Toolkit 2.0 RC2 Now Available

[pjulien]

OK, this issue was actually that I had other projects in the app
server running with GWT 1.7.  It seems we can't run both side by
side.  The problem arises if the jar is pre-deployed or directly in
another war

Weird Spacing in ScrollPanel

[Tyler]

Hello everybody.

I'm developing an application that needs to return Local Search
results in a small ScrollPane. I am choosing, however, to manually
parse the search results so that I can display some particular
information without the rest of it.

The way that I am accomplishing this is shown here:

DecoratorPanel
-ScrollPanel
  -VerticalPanel
 -VerticalPanel
 -HTML
 -HTML
 -HTML
 -VerticalPanel
 -HTML
 -HTML
 -HTML
 -VerticalPanel
 -HTML
 -HTML
 -HTML

When I do this, however, I get one strange error. There are HUGE
spaces between the VerticalPanels which hold the HTMLs. I am hosting a
screenshot of the issue at students.cec.wustl.edu/~tbt1/screenshots/
weird.jpg .

I have used "panel.setSpacing(0);" but to no avail.

If anybody has a suggestion as to what may be causing this, I'd really
appreciate it.

Confused by java.util.Collections$UnmodifiableMap problem when using Window.Location.getParameterMap() : Source Code Included.

[redboffin]

Hello All :-)

I am building a sandpit web application using GWT that is hosted on
App Engine and displayed within facebook as a canvas app.

I am trying to implement validation, using
http://wiki.developers.facebook.com/index.php/User:Google_Web_Toolkit#Security_and_Authentication
as a guide.

The problem I am encountering is that when I try to use the Map
returned by Window.Location.getParameterMap() a java.util.Collections
$UnmodifiableMap problem occurs, even though I'm not modifying the Map
(at least I don't think I am modifying the Map).

I would be really grateful if someone could take the time to help my
understand what I am doing wrong here or point out where I should post
this problem if this forum is not a suitable place to raise this
problem.

Thank you in advance :-)

Source Code Below.

The onModuleLoad() code within my EntryPoint class is below;

fbValidationService.test(Window.Location.getParameterMap(), new
AsyncCallback() {

public void onFailure(Throwable caught) {

// Show the RPC error message to the user

RootPanel.get("serverResponse").add(new 
HTML("Remote Procedure
Call : Test 261109 10:51 - Failure"));
RootPanel.get("serverResponse").add(new 
HTML(SERVER_ERROR));
RootPanel.get("serverResponse").add(new 
HTML(caught.getMessage
()));
RootPanel.get("serverResponse").add(new 
HTML("Stack Trace"));
StackTraceElement[] stackTrace = 
caught.getStackTrace();
for(int i = 0 ; i < stackTrace.length ; i++) {
StackTraceElement element = 
stackTrace[i];
RootPanel.get("serverResponse").add(new 
HTML(element.getFileName
()));
RootPanel.get("serverResponse").add(new 
HTML(element.getClassName
()));
RootPanel.get("serverResponse").add(new 
HTML(element.getMethodName
()));
RootPanel.get("serverResponse").add(new 
HTML(Integer.toString
(element.getLineNumber(;
}

}

public void onSuccess(String result) {

// Show the RPC result to the user

RootPanel.get("serverResponse").add(new 
HTML("Remote Procedure
Call : Test - Success"));
RootPanel.get("serverResponse").add(new 
HTML(result));

}

});

The test() method within the RemoteServiceServlet object is below;

/**
 * Validation Test
 * To generate the signature for these arguments:
 * 1. Remove the fb_sig key and value pair.
 * 2. Remove the "fb_sig_" prefix from all of the keys.
 * 3. Sort the array alphabetically by key.
 * 4. Concatenate all key/value pairs together in the format "k=v".
 * 5. Append your secret key.
 * 6. Take the md5 hash of the whole string.
 * @param fbQueryStringParams
 * @return String
 */
public String test(Map>
fbQueryStringParams) {

String appSecret = TinyFBClient.APP_SECRET;
String fbSig = fbQueryStringParams.get("fb_sig").get(0);
StringBuilder sb = new StringBuilder();
TreeMap sortedMap = new TreeMap();

// Get a Set view of the Map of query string parameters.
Set>> mapEntries =
fbQueryStringParams.entrySet();

// Iterate through the Set view, inserting into a SortedMap all
Map.Entry's
// that do not have a Key value of "fb_sig".
Iterator>> i =
mapEntries.iterator();
while(i.hasNext()) {

Map.Entry> mapEntry = 
i.next();

if(!mapEntry.getKey().equals("fb_sig")) { // 1. Remove 
the fb_sig
key and value pair.


sortedMap.put(mapEntry.getKey(),mapEntry.getValue().get(0)); // 3.
Sort the array alphabetically by key.

}

}

// Get a Set view of the Map of alphabetically sorted Map.Entry
objects.
Set> sortedMapEntries = 
sortedMap.entrySet
();

// Iterate through the Set view, appending the concatenated 
key's
and value's
// to a StringBuilder object.
Iterator> ii = 
sortedMapEntries.iterator();
while(ii.hasNext()) {

Map.Entry mapEntry = ii.next();

// 4. Concatenate all key/value pairs together in the 
format "k=v".
sb.append(mapEntry.getKey().replaceAll("fb_sig_","")); 
// 2. Remove
the "fb_sig_" prefix from all of the keys.
  

Verification Email Process

[Henry]

Hi guys,

I have my GWT application and I need to implement a process to verify
the email address when someone creates a new account.
I've the URL (www.XX.com) which give me the whole application
every time I hit it.
In my process I'll send an email after the successful creation of the
account, this email will have a link inside like that (www.XX.com?
method=verify&username=FFF), by hitting this URL the server will give
me the application again like the first time, then on the onModule()
of my entryPoint class, I'll take the parameters of this URL, and in
that case, I'll make and asyncronohus call to the server to verify the
email and wait for the callback to show a panel to the user saying
that the email has been verify. Before getting that callback I can
show something saying that the email has being verified while I'm
waiting for the callback.
Is it the right way to go?

Thanks in advance.

how to make communicate "two rootPanels"?

[loveley]

hi,

I think I found a method to have some GWT components on a HTML page, 
nothing miraculous : I create the components in eclipse, assign them to 
a RootPanel.get("truc"); and in the HTML page generated by eclipse I add 
a div with the id="truc".
If I want to modify the HTML page I only have to keep the script tag and 
the id I mentioned above.

but I have a question : is there a way to make two components (ie 
identified by its rootPanel) communicate, in the java code and in a way 
that e.g. in a first component I enter in a textBox a string "abc", I 
click on a button in this component, and immediately the second 
component's label has as text the content of the textBox?

thank you,

olivier.

Re: Full GWT Website with MS SQL Server 2008

Hey Joe, nice work, as I am new to GWT I don't know, but I guess it's
possbile, can we have the drop down to get dropped when clicked anywhere on
the dropdown rather then only when clicked on the arrow on the rightmost
side, that will make the clicking easier.

I cannot remember. To be sure, are we talking about the view that has an 
icon that is a blue globe containing a stylized "g"? I see in RC2 it's 
now called "Development Mode". If that's the view, I open it via the 
"Debug" perspective. Rarely, if ever, do I explicitly open the view. In 
RC1 & RC2, I try to minimize, rather than close it.

FWIW, this failure hasn't occurred again.

I sometimes use Eclipse in an X environment where the server and client 
are different machines. It may be that the subject of this thread was a 
result of such a switch. I have noticed that Eclipse sometimes fails to 
start correctly after switching X servers. In such cases, Eclipse fails 
when opening one or more Editor Views. The error message is displayed 
using the Eclipse "details" error widget. The message associated with 
this thread wasn't displayed using that error widget. I'll capture the 
associated message and post to this thread when next Eclipse fails to 
open an Editor View.

Re: flextable getcellcount and clear issue...

can u post the code snippet for clearing cells.

i guess you might be doing table.clear .. that only removes the widgets from

 u can try doing table.removeRow(index);

Subject: Google Web Toolkit 2.0 RC2 Now Available

Hi everyone,

We're getting close! GWT 2.0 SDK RC2 and Google Plugin for Eclipse 1.2 RC2 are 
now available for you to try.

Download the GWT 2.0 SDK RC2 here:
http://code.google.com/p/google-web-toolkit/downloads/list?can=1&q=gwt-2.0.0-rc2

The full documentation is still a work in progress, but you can find 
instructions for using the updated SDK and Eclipse plugin here:
http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC

We've resolved several issues since RC1 and we feel pretty darn good about it, 
but as always, we caution you against using RC2 in production.

Windows users who have previously installed the Google Web Toolkit Developer 
Plugin for IE will have to uninstall the old version and install the new 
version. This action is required because the file locations have changed. The 
RC1 installer required administrative privileges, but the new installer does 
not. Use the following steps:
1. Open Control Panel
2. Select Add/Remove Programs
3. Select Google Web Toolkit Developer Plugin for IE and click uninstall
4. During your next attempt to use GWT 2.0 development mode in IE, you will be 
prompted to install the GWT Developer Plugin, which will download an updated 
installer that does not require administrative privileges

We are eager to get your feedback, both good and bad, in the Google Web Toolkit 
Developer Forum:
http://groups.google.com/group/google-web-toolkit

If you find specific bugs to report, please do so at the GWT Issue Tracker:
http://code.google.com/p/google-web-toolkit/issues

Cheers,
John LaBanca, on behalf of the GWT team

FormPanel SubmitCompleteEvent not getting full results that the server is sending back

[Mohamed Mansour]

Hello,

I am using FileUpload widget within a FormPanel. Basically, I am sending an
XML file to FileUpload to test.jsp, where that JSP file is sending that text
file back wrapped in a  tag.

The problem is that event.getResults() from the SubmitCompleteHandler trims
off the result from the beginning. The XML File I am sending is 110lines,
where the result should be:

> 

  Import XML

  true

  

   

  




But I am only getting the following back:

>   true

  

   

 




Any ideas why? The code snippet is as follows:

*GWT:*

> FormPanel form = new FormPanel();

form.setAction("../test.jsp");

form.setEncoding("multipart/form-data");

form.setMethod("post");

form.addSubmitCompleteHandler(new SubmitCompleteHandler(SubmitCompleteEvent
> event) {

   Log.debug(event.getResults());

   // Window.alert(event.getResults());

});


*JSP:*

> <%

   ... Read the buffer and place it into a String



  //  Prints on the console the correct full "XML" that I sent through
> FileUpload.

  System.out.println(content);

  out.println("" + content + "");

  out.close();

%>

Should we use maven or not for a project?

[jbdhl]

I'm about to start a new GWT project but can't decide weather to use
maven or not - partly because I'm completely new to maven. Are there
really large benefits from using maven? I've heard, that not even
google is using it, and this worries me a little.

Our project will be a bit of a mix of various stuff and I don't know
how well this fits into the maven structure:

  * besides the usual client/servlet code, we will build a few smaller
java tools to be run periodically by cron.

  * we will use a bunch of scripts written in various languages to
solve different tasks

  * the project will include a bunch of documentation and text
documents

All in all: what is your recomendation? Maven or not?

To get the SubmitCompleteEvent, you have to send the result back as
text/html, which also means it'll be interpreted as HTML by the
browser (even if it gets loaded in a hidden iframe, it still is an
iframe).
Here, the  is ignored because it's not a known element, then
Import XML is parsed as the document's title (the one
that'd be displayed in the window title bar or tab if the document
were showed in a "full window" rather than an iframe), then again
 is ignored, and finally "true" implies the  start tag
(and is parsed as the very first document's body content).
Given that SubmitCompleteEvent::getResults() returns the
document.body.innerHTML of the iframe, it effectively starts with the
"true" and everything before it is somehow "ignored".

Conclusion: if you want to send anything containing "<" and "&" in
response to a FormPanel submission, escape it (< and &) on the
server-side and then unescape it on the client-side.

Re: Should we use maven or not for a project?

[CI-CUBE]

I found maven pretty heavy and can live w/o it. If some day I feel the
need to have something like that I can use it anyway, no problem. Just
my personal opinion.

GWT Custom Widget => How to do event handling...

[Chris]

Hi Guys

I'm trying to build my own custom widget. How can i add event handling
to the widget?

Here's there idea...

I have a Composite (my View), on which I add a Timeline Widget
The Timeline widget has many bands TimeBand
and each TimeBand has many TimeEvents.

I've used the DOM.createDiv(), and then GwtExt to have full control
over setting styles on elements. I need to do this (I think, but I'd
love to proven wrong), cos each of my events (individual divs) needs
to be carefully positioned on a scrollable div, and so on...

Anyway, I've kind of got the layout working to a certain degree. What
I'm not sure if how to get the Mouse event handlers firing and
captured so that i can dynamically do stuff to my widget...

so for example:

class Timeline extends Widget {
Element t;

Timeline() {
   t = DOM.createDiv();
}


public void addTimeBand(TimeBand band) {
t.append(band.getDiv());
}
}

class TimeBand {
ELement band;
TimeBand() {
band = DOM.createDiv();
}

public Element getDiv() {
return band;
}
}



I've tried a number of different things to get the event handlers
working but I can't seem to add events to my TimeBand
All I want to do is track mouse clicks and mouse movements.

Cheers
Chris

A third axis?

[fker...@gmail.com]

A question about deferred binding... If I define a new property in the
gwt.xml module file; say,



and an appropriate generator



that will get the time of the day, and generate the property value
accordingly.

Of course, I would have some deferred binding rules that would replace
some classes with other classes, depending on the timeoftheday
property.

(Please, bear with me, and assume there is some valid reason for using
different classes at different parts of the day!)

Am I totally mistaken, or would then the compiler generate FOUR
(because of the four values of the property) times as many versions of
the JavaScript code?

That is, if you supported 5 languages for i18n purposes, GWT would
produce 5 times 6 versions of the code (5 languages times 6 supported
browser types) -- with my timeoftheday variable, would that become 5
times 6 times 4 versions?

GWT 2.0 R2, implementation of CssResource css();

[Ewald Pankratz]

I'm too stupid to understand how all the things are connected. I tried
to find out where the abstract methode css() is implemented. It's in
Mail sample of GWT 2.0 R2.

  interface GlobalResources extends ClientBundle {
@NotStrict
@Source("global.css")
CssResource css();
  }

thanks

Nope. I had to exit Eclipse to fix this error.  The Project Explorer view

Re: Back button functionality problem

[Zak]

1 - Use History Tokens to change the app's URL when you change state.
This will trick the browser into thinking the use has navigated to
different pages. More info:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/History.html

2 - Could you provide more information? Perhaps the code that's
broken?

3 - This functionality works on  tags, which is GWT's Hyperlink
widget: 
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/Hyperlink.html

4 - This code should do the trick:

Window.addResizeHandler(new ResizeHandler() {
  public void onResize(ResizeEvent event) {
 // do stuff
  }
});
