Re: GWT integrated with JSF
The jboss doc link gives heaps of food for thought. Just wondering, am i correct to say that G4JSF became ajax4jsf which then became richfaces ? This kinda makes it quite confusing when i have jsf and gwt and no idea what i can use to glue it together :P An example would be very helpful :) on the seam application, and maybe on the other ways of pulling information. :) I have used spring in the past, tho not starting out and it already had a very structured hierarchy and as i'm a fresh out of uni, and this is mostly a green feilds type project, there is way to many technologies to look at and yet not enough time in the day. :/ The jsf website that i'm now working on had a pre existing database backend in oracle. The developer before me used netbeans out of the box features to generate a brand new interface to the oracle database. (can't remember the backend infrastructure, will find out in the morning when i'm at work) The simple stuff is done and now its to the hard stuff. i have thought of doing through GWT DOM objects, but i would like a cleaner way of keeping state, the application will be doing big edits to the database backend if they apply the changes they make and i would like to allow any not pre-commited changes to either linger till out of session of save for next session which means that GWT DOM object pulling for the id/keys won't do. Google group discussions seems to be quite nice, tho i do miss the spell check feature that is in gmail. :) On Dec 14, 5:50 pm, "olivier FRESSE" wrote: > Hi will, > I work on a project where we use GWT, seam and facelet.

Why the form isn't getting submitted?
Hey,
I'm trying to use FormPanel to submit values to a servlet:
+
form = new FormPanel();
form.setAction("/webcontext/command");
form.setMethod(FormPanel.METHOD_POST);
form.setEncoding(FormPanel.ENCODING_URLENCODED);
form.addFormHandler(this);
// controls table is created with FlexTable controlsTable =
new FlexTable();
form.setWidget(controlsTable);
groupName = new Label("Group name:");
group = new TextBox();
group.setName("groupName");
submit = new Button("Create Group");
submit.addClickListener(this);
cancel = new Button("Cancel");
cancel.addClickListener(this);
// Then I'm adding the labels and form's controls to the controlsTable
public void onClick(Widget sender) {
if (sender == submit)
form.submit();
else
this.hide(true);
}
++
But when clicking on "Create Group" button, no request is made to the
servlet (proofed by FireBug and the debugger).
Why my for isn't getting submitted?
Thanks.

How to modify RichTextArea
I try to modify the functionallity of the RichTextArea Wdiget. As you know it is possible to format text as bold for instance, which wraps the selected text with my text. Is it possible to format text by wrapping my own tags, like: my text. Or is there a way to get cursor position and selection?

Re: J2EE and debug in hosted mode
Well, that depends on your IDE and your app server, and unfortunately I use Intellij and JBoss. In JBoss the magic command is: set JAVA_OPTS=-Xdebug - Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS % which is in the JBoss startup script. I then set up a debug session within IDEA that starts up JBoss inside IDEA and connects to it for debugging purposes on port 8787 (IDEA conveniently knows how to do this). Then I start the GWT module in hosted mode also in debug. As a result the whole stack is running in debug and break points can be set anywhere. It looks like you can do a very similar thing with netbeans/glassfish: http://weblogs.java.net/blog/arungupta/archive/2007/06/debug_applicati.html I think you actually end up with two separate debug sessions, one for your GWT app in hosted mode, and a second remote debug session for what you have deployed on the app server. However this makes no practical difference to debugging - GWT calls your server as per normal and execution will halt at break points wherever they are in the stack. regards gregor On Dec 14, 3:27 pm, Bandesz wrote: > Thx for the answer, but I need an exact howto, how can I debug the > whole J2EE application with Hosted Mode using Glassfish and Netbeans. > > As I said, I searched a lot and haven't found a good description. > > Bandesz > > On Dec 8, 4:34 am, gregor wrote: > > > couple of approaches > > > 1) Simply use -noserver option.

Re: J2EE and debug in hosted mode
When you run in hosted mode, you have 2 java processes running. The glassfish one, and the GWT shell. Debugging the glassfish side is easy, it comes OOTB in Netbeans. Debugging the client side is quite easy too. You just need to change the way the GWTShell is launched : java *-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n * -Xmx256M -cp "$APPDIR/src:$APPDIR/bin:/home/ofe/dev/gwt-linux-1.5.3/gwt-user.jar:/home/ofe/dev/gwt-linux-1.5.3/gwt-dev-linux.jar" com.google.gwt.dev.GWTShell -out "$APPDIR/www" "$@" ext.test.MyAppli/MyAppli.html; next you can attach the netbeans debugger to the Shell. Is it what you're looking for ?

Re: J2EE and debug in hosted mode
I wrote it wrong, not the debug is the problem, I just want to run the enterprise application (EJB+Web) in Hosted Mode, I wrote debugging because hosted mode runs if I debug the web application. If I understand correctly, the build-gwt.xml is responsible for the hosted mode. If I run the ent. app., the build.xml simply compiles the EJB and the Web project, makes an EAR package, and starts glassfish in debug mode. So how can I write a build file which runs the whole application in gwt hosted mode? This is a bottleneck in my development, because the deploy time is now more than 1 minute. If I could use as I wrote it, the hosted mode shows the changes in couple of seconds, and the autodeploy on the server side is just seconds.

Re: How to have a layered panel?
All,
I managed to add the GlassPanel with little effort and for the most
part is looks great. I was about to ask how to get it to not disappear
upon click but figured it out before i could post the message :).
Thanks all. You've been a great help. In case anyone was interested,
I'm using it within a tabbed panel when one tab is active with some
static variable that controls the editable nature of either tab.
Although of course, the parent panel of the GlassPanel should be
AbsolutePanel.
Thanks
Suri

Generators and Generics
I have to write a generator whose marker interface has a generic typeMy
marker interface will be like this:
public interface MyInterface {
}
the subinterfaces will provide a type for that parameter, like:
public interface MySubInterface extends MyInterface {
}
and then I will call:
MySubInterface = GWT.create(MySubInterface.class);
Inside the generator, how can I find out what type was used on T parameter?
(Customer, in this case)

Re: Error in RPC : Regarding Serialization
The problem is:
Caused by: com.google.gwt.user.client.rpc.SerializationException: Type
'[Ljava.lang.String;' was not included in the set of types which can
be serialized by this SerializationPolicy or its Class object could
not be loaded. For security purposes, this type will not be
serialized.
which probably indicates there is nothing in any of your RPC service
interface declarations that mentions String specifically, so it is not
included in the RPC "white list". Are you declaring the ArrayList like
this:
ArrayList myService(...) {
ArrrayList myList = new ArrayList();
.
return myList;
}
If not then this will probably make the problem go away.

Re: J2EE and debug in hosted mode
The simplest is to run hosted mode with the -noserver flag. Then you deploy your EAR with your Ant script once and run & debug your GWT client code in hosted mode just hitting the refresh button as you go.

can we disable the default scrollbar in HorizontalSplitPanel
I am using a horizontalSplitPanel to divide my window into two parts- left part has fixed width while the right one occupies the entire remaining space. I want to hide the fact that i have used SplitPanel by removing the default scrollbars the appear whenever the inner panels go out of size and disabling resizing capability of the splitPanel. Is there a way to achieve it? I definitely need a way to remove the scrollbars. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Request Builder problem
Hi guys,
I have searched the forum and couldn't find the solution. Here is my
code.
public class Getter {
private String url = "php/Main.php"; //fix url never
changes
private RequestBuilder builder = null;
private String result = null;
public Getter() {
builder = new RequestBuilder(RequestBuilder.POST,
URL.encode(url));
}
public String getData(int id, final String section){
String param = "nId=";
param += Integer.toString(id);
param +="&";
param +="sectionName=";
param += section;
builder.setHeader("Content-Type", "application/x-www-form-
urlencoded");
try {
builder.sendRequest(param,new RequestCallback(){
public void onError(Request request,
Throwable exception) {
calxx("error");
}
public void onResponseReceived(Request
request, Response
response) {
calxx(response.getText());
Window.alert("-"+response.getText());
TemoStorage.temp =
response.getText();
}
});
} catch (RequestException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
GWT.log(TemoStorage.temp, null);
return TemoStorage.temp;
}
private void calxx(String kk){
result = kk;
}
}
TemoStorage.temp is static string field.
now, when I call the method getData from the other class. I get the
window alert displaying the apropriat server message. But this method
return null. GWT log also says null. How do I return apropriat
"server message" with this method.
Thanks

vertical alignment doesnt work while horizontal alignment does
I am creating a vertical panel which contains 3 panels in it. now i want the topmost panel to always remain at the topmost region touching the top of the window. Similarly the bottommost panel should remain at the bottom touching the lowest part of the window. the middle panel should occupy the entiore remainn=ng space between these two. I tried using vertical alignment in CSS as well in GWT code somewhat like vertical-align: top; // for top window vertical-align: bottom; //for bottom window It doesnt work as expected. AM i doing it wrong? is there a way to do it using CSS ??? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: can we disable the default scrollbar in HorizontalSplitPanel
AFAIK there is no way you can disable the internal ScrollPanels in HSP. HSP internally puts each widget (left & right) inside a ScollPanel automatically for you, and if either left of right widgets grow they will kick in, end of. HSP is also declared final, so it is impossible to extend the class to attempt to modify this behaviour. If you want to completely disable HSP resizing (i.e you do not want the user to able to move the splitter) why use HSP? Why not use a 2 cell HorizontalPanel with a fixed left cell size and the right 100% width?

Re: vertical alignment doesnt work while horizontal alignment does
I think you need to work with VP.setCellHeight(widget,height). The basic technique is to set the the top and bottom widgets to say 1% height and the middle one 100% which will minimize the height of top and bottom depending on contents and middle will fill out the rest. Or you can give a hard pixel height value to top and bottom and 100% to middle.

Re: Problem with GWT RPC call with List of DTO objects
It's odd that the RPC documentation still talks about typeArgs. I've
just double checked, and I have systematically removed all typeArg
statements relating to RPC parameters/return values from the last
project I upgraded to 1.5.3. All now replaced with 1.5. syntax and it
works fine.
My assumption is that specifying the type for collections in 1.5
syntax (i.e. List) means the GWT compiler uses that info in
the same way it used to rely on typeArg tags. I sincerely hope I'm
right about that..but those docs have got me worried.

Why are GWT JavaScript objects not enumerable?
Dear All,
First, thanks for all your hard work on GWT. It really is a fantastic
framework!
Is there a reason why GWT-compiled JavaScript objects are not
'reflectable' like regular JavaScript objects are? When I do (in
JavaScript):
for( var s in obj )
{
alert( obj[s] );
}
I don't see any properties or actions for GWT-compiled objects, but I
do for regular JavaScript objects. I don't much understand the 'var s
in obj' technique, but it seems it should be able to reflect GWT
objects? For example, when I do...
alert( obj[ '@org.foo.Foo::myMethod()' ] );
...then I CAN reflect the method okay?
Regards,
Richard.

open a listbox programmatically...
I have to show a listbox programmatically ( as I let the user
rearrange the order of the items ). I tried the following code but i
get an exception...
public static native void fireClickListener(ListBox list) /*-{
var cl =
li...@com.google.gwt.user.client.ui.focuswidget::clickListeners;
c...@com.google.gwt.user.client.ui.clicklistenercollection::fireClick
(Lcom/google/gwt/user/client/ui/Widget;)(list);
}-*/;
[ERROR] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: JavaScript TypeError

(ModuleSpace.java:270)

(JavaScriptHost.java:137)
Maybe the "cl" referring to the clickListeners is not correct...any
ideas appreciated.
Thx

Re: open a listbox programmatically...
I see that the clickListenerCollection is null. I am wondering how the popup is displayed since the listbox is created using a DOM.createSelect. So it is the browser handling this click event - so there is no way then to programatically force the click ? -- pady --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Suggestions for improving GWT group
I would find this group more useful and would participate more if there were "sub-groups" of some kind.

Re: Generators and Generics
I don't know the answer to your question - I'm guessing generic
markers are not possible?
But, I simplified a similar problem by launching the generator on the
"real type" - in your case Customer; you can still extend your
implementation of MySubSubSubInterface in the generator.
:)

Re: Event/Listener???
That's exactly how listeners work. Let's say you have a Button,
TextBox and a Label. Each time the Button is pressed, you want the
Label to display the text in the TextBox. You would do some like the
following:
TextBox text = new TextBox();
Label display = new Label();
Button button = new Button();
// now you need to add the listeners
button.addClickListener(new ClickListener() {
onClick(Widget arg0) {
display.setText(text.getText());
}
});
RootPanel.add(text);
RootPanel.add(display);
RootPanel.add(button);
Keep in mind that if you want the TextBox and the Label to be
accessible from the anonymous inner class, you'll need to make them
fields or final (they can't be local variables).

Re: how to implement history mechanism for tree structure
Have a historyListener in the class having the reference to
borderlayoutpanel. Then onCLick of the tree button u can fire
History.newItem("sometoken")
In the onHistoryChange() you check for the token and refresh the central
panel accordingly.
Hope this helps.

Re: can we disable the default scrollbar in HorizontalSplitPanel
I tried using a horizontal panel as a main panel with wisth and height to 100%. Inside it i created two different verticalpanels. The one on left hand side has fixed width set to 233 pixels using css. Now the right child panel should occupy the remainng space in the screen. I tried setting width to 100% in css as well as in gwt code. It doesnt work. By default a panel occupies only the space its content requires. So an empty panel doesnt have much width even if it occupies the entire height. Inside the rightside panel i have to use 2 child widgets which occupy entire width. How should i got about it?Is there a way to get window dimesnions in css so that i can calculate the width in pixels in the css itself?

Re: vertical alignment doesnt work while horizontal alignment does
I have tried it. The middle panel actually doesnt occupy the entire height since it is empty. The bottom panel also doesnt really stay at the bottommost part of the window as it follows the middle panel. I want the top panel to occupt certain fixed pixel height. The middle and bottom panel should occupy the remaing space which i would soecify in percentage in css. How do i go about it?

Centerpanel doesnt show widgets
Hi all,
I have this strange problem :
I have a main panel which is borderpanel .
When i set html for the center panel i see the changes, Howeve, when i
add a widget (onclick event) ithe widget is not seen in the center
panel.
Have an idea?
Here is the module load :
public void onModuleLoad() {
/**
* START - Define RPC service callback for future ajax requests
*/
ServiceDefTarget endpoint = (ServiceDefTarget) serviceAsync;
// String moduleRelativeURL = GWT.getModuleBaseURL() + "../
includes.php";
String moduleRelativeURL = "http://localhost/idlogger_v8/
includes.php";
endpoint.setServiceEntryPoint(moduleRelativeURL);
/**
* END - Define RPC service callback for future ajax requests
*/
//Main panel to add to root view
Panel panel = new Panel();
panel.setBorder(false);
panel.setPaddings(15);
panel.setLayout(new FitLayout());
Panel borderPanel = new Panel();
borderPanel.setLayout(new BorderLayout());
Panel northPanel = new Panel();
Image img = new Image("images/header_icon.jpg");
img.setWidth("315");
northPanel.add(img);
northPanel.setHeight(72);
northPanel.setWidth(450);
borderPanel.add(northPanel, new BorderLayoutData
(RegionPosition.NORTH));
//add south panel
Panel southPanel = new Panel();
southPanel.setHtml("south panel");
southPanel.setHeight(100);
southPanel.setCollapsible(true);
southPanel.collapse(true);
southPanel.setTitle("South");
BorderLayoutData southData = new BorderLayoutData
(RegionPosition.SOUTH);
southData.setMinSize(100);
southData.setMaxSize(200);
southData.setMargins(new Margins(0, 0, 0, 0));
southData.setSplit(true);
borderPanel.add(southPanel, southData);
BorderLayoutData westData = new BorderLayoutData
(RegionPosition.WEST);
westData.setSplit(true);
westData.setMinSize(175);
westData.setMaxSize(400);
westData.setMargins(new Margins(35, 5, 0, 5));
westData.setCMargins(new Margins(35, 5, 5, 5));
borderPanel.add(getWestMenuPanel(), westData);
centerPanel = new Panel();
centerPanel.setHtml("center panel");
borderPanel.add(centerPanel, new BorderLayoutData

Re: How to modify RichTextArea
Maybe it is possible to do this by using the setHTML() method:
myRichTextArea.setHTML("This text is colored
red...");

Re: GWT and existing project
Hi, As per my latest experience, same thing ihave done. what you need to do that u create a separate GWT project with your new stuffs and then compiled that with xs-linker. Now, you deploy the compiled source to your server in a jar or war form. then, load the GWT project , you can get the all neccesaary information for loading from this link i.e http://developerlife.com/tutorials/?p=231 Plz let us know if you have any difficulties.
