Re: GWT Sticky Sessions
Hi there
from my experience ... you are barking at the wrong tree so to speak.
it's a long time that I'm not using GWT anymore (not my choice, but i had
to) but i don't think that it's GWT's problem
to check the jsessionid you could use the Chrome's developer tools o
firefox - firebug and look at the network tab there you should see the
headers sent to the back-end (the jsessionid should be present in a cookie
or in the request).
anyway you said mod_jk that says to me that you have an Apache HTTPD before
the Tomcat
I usually use mod_proxy_ajp (which i would recommend, but about that we
could talk some other time)
a very important thing when implementing load balancing it's the jvmRoute
parameter on the tomcat.
In every tomcat you shold edit in the server.xml the line saying
adding the an attribute jvmRoute, with a string at your discretion but
different for every server.
...
that makes the Tomcat add that little string at the end of the jsessionid (*
jsessionid*=AS348AF929FK219CKA9FK3B79870H would become
*jsessionid*=AS348AF929FK219CKA9FK3B79870H.t1
on the first server t1 and so on).
that little string there says to the Apache on which node the session was
created and therefore where it should send the request.
from what I've understand from reading this
http://blogs.encodo.ch/news/view_article.php?id=18 looks like the jvmRoute
value should be the same as the worker name or/and vice-versa.
that's about it, hope it helped
See ya

Re: GWT + DB Connection -- Failure when deployed!
as far as I know jdbc connection is not allowed when deployed to "the cloud"/appengine.google.com. all you could do if you want to use your own database server would be to implement a "service" on your DB Server to provide the data in json or XML. and in your application to parse that data. i hope my info is still correct, i hadn't used GAE in the last 4-5 months.

Re: Date Range
a "simple" idea that comes into my mind right now: draw the date picker widget, and add valueChange listener, on value selection change the css for the selected date and add the date to an list an . on the first click add the date to the list and highlight the date, on the second click remove it from the list and change the "css" back (un- highlight). that would be the big picture, but i can't give exact directions.

Re: How to get rid of standard.css
if you still plan to use the resources from the default theme instead of using use this will put the css and the images in your compilation folder, but will not inject the css file to your app so that now you could add their css file first and then your css this way you still benefit from their css classes and you will also be able to override the because your css will be loaded last hope it helps Good luck On Apr 8, 1:40 pm, mariyan nenchev wrote: > Remove it from the gwt.xml -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: web.xml
for properties on the clientSide :
you should take a look at Messages
(com.google.gwt.i18n.client.Messages)
you'll need to have an interface that extends Messages
and a .properties file for the values
for example
- CommonMessages.java
import com.google.gwt.i18n.client.Messages;
public interface CommonMessages extends Messages {
String usernameLabel();
@Key("field.password.minLength")
@DefaultMessage("6")
String passwordMinLength();
@Key("err.field.empty")
String fieldEmpty(String param);
}
CommonMessages.properties
usernameLabel=Username
field.password.minLength=6
err.field.empty= Field "{0}" is empty !
both the java and properties file should be in the clientside (so that
the gwt compiler would have acces to them)
and in the code
you would have
CommonMessages commonMessages = GWT.create(CommonMessages.class);
commonMessages.fieldEmpty("First name");
commonMessages.usernameLabel();
if you need acces to the properties from the server side then the only
way i think it's by having them returned by a RPC call

Re: New module does not get called
an EntryPoint is called when you explicit call it. i mean starting with the default projrct that the plugins creates it it has an module and an entry point if you create an another module with it's entry point, eihter you add the script to the html page that you have, or u create an another html page that will use this module+entry point. ... more details about your project would help me to explain better. in my opinion, and my way of using gwt, the aproach shoule be like this an entryPoint usualy it's = a html page (jsp, what ever) and vice- versa, an html page has an entrypoint On Mar 13, 7:45 pm, Szabó Árpád Zoltán wrote: > Have you added your new module to the list of Entry Point modules at > > project->properties ->Google->Web Toolkit ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

... choose .. what? ... do do what ? if you want a file browser/selector so that the client would acces his files file uploader () it's the only one i cant think of if u want to browse/select files from the server ... than i don't know just as an idea, for client file selection, you could have an file input and hideit and make your custom widget and on clicking a certain button or something pass the click to the file input. something like what he is trying to explain here http://www.quirksmode.org/dom/inputfile.html Cheers On Mar 5, 12:26 pm, cupakob wrote: > Is there a file chooser (not file uploader) widget? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Window.open can not work in IE
try putting "_blank" as target instead of ""
or if is not a new window what you want, put "_self" or you could try
"_top"
but _self and/or _blank should do it

Re: DatePicker disabling specified dates
after re-reading that message I find it a little to ... mixed up.
one idea was that you could use a ShowRangeHandlers that you'll
add it to your DatePicker object,
on the onShowRange() method you'll need to take the date list between
the start and the end of the range, and for the dates that are <= your
lastDisabledDate do a call of
datepicker.setTransientEnabledOnDates(false,date);
or you could add the disabled dates to a list and call
datepicker.setTransientEnabledOnDates(false,disabledDateList); //
this will call the first method so will be no gain
this approach is time consuming it's a heavy load when there are many
days to disable
a second idea:
the default constructor DatePicker() calls the following constructor
DatePicker(MonthSelector monthSelector, CalendarView view,
CalendarModel model)
with the following arguments
new DefaultMonthSelector(), new DefaultCalendarView(), new
CalendarModel()
the CalendarView (DefaultCalendarView) is the class that takes care of
the dates isEnable()
because you don't have access to that second constructor you'll have
to make your own DatePicker that extends DatePicker so that you could
access it, and instead of using the DefaultCalendarView use your own
class made from the code of this one and change in the inner class
CellGrid the method isEnabled() so that it'll make the check if the
date is < lastDisabledDate
lastDisabledDate would be set by a method of your custom DatePicker to
your custom CalendarView.
this is a more elegant approach (I think) and also could be used to
disable specific dates (a list of dates), or a specific dayOfWeek
good luck

Re: standard overrides own css no matter what?
you are doing nothing wrong, that's just the way it works. the problem is that the theme's css are loaded/injected "last" at the same time as when the module is loaded/injected there are 2 ways to change that. 1: instead of using use this way you will add the resources(css, images, ...) of this theme to you module compilation, but it wont inject the css when the module is loaded and you must add the css "by hand" ... in the html(or whatever) page and make sure it's before you css 2: the other workaround is to add "! important" to all the properties of all the classes of you stylesheet good luck On Feb 23, 3:15 pm, Andrew Hughes wrote: > guess: perhaps it's the order in which the css files are listed and thus > loaded. > > On Sun, Feb 21, 2010 at 3:44 AM, Pico wrote: > > Hi all, > > I'm quite new to GWT.

Re: How to provide a local css resource file with a Module
Sorry, my bad, i didn't provide enough info as i said you should take a look into the gwt-upload library so in the gwt-upload it's like this, the css is in the "public" folder which is on the same level as the "client" folder you have to take care to add them to your jar, for GWT the "public" folder is special, it take every thing in it and it puts it in the folder where the gwtCompilation will be as it was done in the older version (in GWT 1.6 the folder public was a "must" it was described as part of an module), the other importnat thing which i forget to say is that in the .gwt.xml of the "consumer" module, when you do the you have to add the tag in gwt-upload usage it asks to add these in my "consmer" module now if think about it ... you might try adding the tag in the gwt.xml of you libModule and check if it's the same result sorry for the incomplete response i gave yesterday, i don't know all these "by hart" i just remembered that i sow them there and told you what's there after a brief analysis. good luck On Feb 23, 9:22 pm, Ashish Khivesara wrote: > Ok.

Re: How to provide a local css resource file with a Module
you should put the css in a folder named public inside your module package, the folder should be on the same level as the client folder there's no need for the specification on the .gwt.xml file you could take a look at the GWT-Upload library it has same situation, their jar contains gwt module with no entry point and css that contains the css-classes for their widgets. good luck On Feb 22, 9:20 pm, Ashish Khivesara wrote: > Any one with a solution for this issue? > I even tried using UiBinder and css in conjunction to solve this issue but > have not been able to. > > Any direction would be helpful. > > Thanks > Ashish > > On Fri, Feb 19, 2010 at 5:52 PM, Ashish Khivesara < > > ashish.khives...@gmail.com> wrote: > > This looks like a bug. > > > Issue: If a module without a entry point includes a stylesheet element then > > the path is considered to be relative to the module that may inherit it. > > This make it rigid and thereby adds a dependency between the inheriting > > module. > > > In my case Music module had this line in the Music.gwt.xml > > > > > Now Home module inherits Music modules. > > > But GWT instead of looking for /music/Music.css, looks for the css resource > > in /home/Music.css > > > [WARN] 404 - GET /home/Music.css (127.0.0.1) 1400 bytes > > > On Fri, Feb 19, 2010 at 5:31 PM, Ashish Khivesara < > > ashish.khives...@gmail.com> wrote: > > >> Well the issue here would maybe because the module here in question does > >> not an Entry point and hence there is no hostpage to inject this css > >> reference into. > >> So this there a way to make sure the inheriting module injects this > >> stylesheet in its host page?? > > >> Thanks > >> Ashish > > >> On Fri, Feb 19, 2010 at 5:18 PM, Ashish Khivesara < > >> ashish.khives...@gmail.com> wrote: > > >>> I need to associate a local css resource file with a module.

Re: How to consume a service from another module (RemoteServiceRelativePath and ServiceDefTarget question)
the problem appears because of the RemoteServiceRelativePath as you
noticed it says relativepath,
one way to fix that is to use your code ((ServiceDefTarget)
gwtService).setServiceEntryPoint("/some/absolute/path");
or use the power of the relative path (that's how i do it, because I'm
lazy)
@RemoteServiceRelativePath("../servX")
which instead of /modB/servX or /modA/servX will become /servX no
matter what module calls it
also you'll need to make the proper changes in web.xml so that the
servlet class will be mapped to the /servX path

Re: GWT Compilation of gwt project with multiple modules
from my experience trying to gwtcompile an module without EntryPoint
throwed an error (don't recall which)
modules/libraries that will be used with included don't need to be
GWTcompiled. exually (don't know how to spell it)
i have noticed that running apps which had this kind of module usage
in eclipse, in the war folder i only get folders (folder with
gwtcompild code with the names given by the rename-to attribute from
the module tag) for the modules that have entry points. so even that I
use code from the other modules i don't get folders for them
also on my production server, where i deploy the app, i run the build
script that only gwtcompiles the modules with the entrypoints, an put
in the webapps\ROOT folder of the tomcat server only the content of
the war folder of my app.
for a (good/correct) gwt compile script try building a dummy app
using the command line with webAppCreator.cmd (check the params) that
will also create a build.xml file which afterwards you could modify it
to suit your needs.
good luck

Re: GWT Compilation of gwt project with multiple modules
the "MyModule" that will be used in MyModuleUsage module does not need
to be GWT compiled ... and even further you can't GWTcomplie it
without an entry point, but you don't need it gwt complied,
in this type of scenario myModule is compiled in java (javac) and made
a jar that has the .class files along with the .java files for the
classes in the (from the) folder that are mentioned by tags.
when you'll GWTcompile the MyModuleUsage module GWT il put in that
compilation all the classes needed for this module to run that
includes the classes from MyModule.
that in info is on AFAIK bases, if someone knows different please
correct me.
for "My question is , the way I am using multiple modules to reduce
files sizes, is it correct or no ?" only the people working on
developing GWT could give u an correct answer, my guess is that it'
wont reduce it. but it would be usefull if you've used MyModule in
other more modules like MyModuleUsage
Hope it helps you and clears some of you questions
good luck

Re: Not able to use External Jar file for DB connection
what JDK do you use ? JDBC4 driver should be used only starting with JDK 1.6, acording to the postgresql site : JDK 1.6 - JDBC4. Support for JDBC4 methods is limited. The driver builds, but the majority of new methods are stubbed out. maybe you will consider in using the JDBC3 version in my apps, i put the jar in the war\WEB-INF\lib folder, and the using eclipse I add it to the build path but one more thing ... i just noticed ... why do you have the appengine in a application that will use an "normal" SGBD ? if i recall well, using appengine you won't be able to connect to the database any way hope any of this helps cheers On Feb 9, 11:24 am, vinod M wrote: > HI, > > Can anyone help me in solving the issue faced while developing the > application using Postgres DB with SmartGWT-2.0 and GWT 2.0, failing > to establish the connection. > > Configuration Details > > Eclipse 3.4 (Ganymede) > Gwt plugin > Appengine 1.3 > GWT 2.0 > SmartGwt 2.0 > Postgres Sql DB > > I initially tried setting external library path for the > 'postgresql-8.4-701.jdbc4.jar' and tried running the server got this > error attached below. > > Code: > > Initializing AppEngine server The server is running athttp://localhost:/ > java.lang.ClassNotFoundException: org.postgresql.Driver at > java.net.URLClassLoader$1.run(URLClassLoader.java:200) at > java.security.AccessController.doPrivileged(Native Method) at > java.net.URLClassLoader.findClass(URLClassLoader.java:188) > > I tried putting the same jar file inside the war/WEB-INF/lib and > restarted the server, and error log reads below > > Code: > > Initializing AppEngine server The server is running athttp://localhost:/ > 9 Feb, 2010 7:00:26 AM > com.google.appengine.tools.development.ApiProxyLocalImpl log SEVERE: > [1265698826728000] javax.servlet.ServletContext log: Exception while > dispatching incoming RPC call > com.google.gwt.user.server.rpc.UnexpectedException: Service method > 'public abstract java.lang.String > com.zo.zotweb.client.GreetingService.greetServer(java.lang.String)' > threw an unexpected exception: java.lang.NoClassDefFoundError: > java.net.Socket is a restricted class.

Re: can not set breakpoint
that's the problem you are missing the ?gwt.codesvr=localhost:9997 from the URL, all the urls need to have that so that your application will comunicate with the eclipse so you'll be able to debug i think that's specified somewhere in the docs. also if you don't have ?gwt.codesvr=localhost:9997 on the url, you won't see the client modfications if you refresh the browser. cheers, take a glance on the documentation for development mode On Feb 10, 9:50 am, go canal wrote: > it ishttp://127.0.0.1:/ > rgds, > canal > > > From: Jason Parekh > To: google-web-toolkit@googlegroups.com > Sent: Tue, February 9, 2010 11:38:47 PM > Subject: Re: can not set breakpoint > > Hi Canal, > > Which URL is your browser pointing at? > > jason > > On Mon, Feb 8, 2010 at 8:51 PM, go canal wrote: > > I have upgraded JDK to 1.6u18. tried the default project greetService, still > the same.> rgds, > >canal > > > From: Jason Parekh > > >To: google-web-toolkit@googlegroups.com > >Sent: Mon, February 8, 2010 11:34:43 PM > >Subject: Re: can not set breakpoint > > >Hi Canal, > > >What version of Java are you running? > >Could you try on a simple project (perhaps the default app created by the > >wizard)? > >I'm assuming the breakpoints do not show the checkmark on top of them (when > >the debugger is connected)? > > >jason > > >On Sun, Feb 7, 2010 at 8:05 PM, canal wrote: > > >hi, > >>searched the group but still can not make it work - can not set > >>breakpoint in the client code > > >>i am using Eclipse 3.5, GWT 2.0.1, with plugin.

Re: RootPanel.get().clear does not clear anything
check what I've said here
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/519854e6a7c77d91?pli=1
but whatch out if you'll do an
RootPanel.get().getElement().setInnerHTML(""); i think that will
remove the iframe that GWT adds it to the document also i don't know
if that wouldn't affect the application, if the gwt will put it back
or you'll end up with some errors

Re: RootPanel.get().clear() does not clear the page
Hi
the clear() method on the HasWidgets objects only removes the child
widgets that had been added to it by using the add method
in you case the logic is kind of ok, the
RootPanel.get("nameofcontainer") is a child of RootPanel.get() in the
DOM point of view, but
but not for the HasWidgets object represented by the RootPanel.get()
an work around would be to do something like
RootPanel.get().getElement().setInnerHTML(""); but the when you'll try
an RootPanel.get("nameofcontainer") you'll get nothing because there
will no more be an object with the id=nameofcontainer
also it's possible to end up with "artifacts" object that you may have
in memory but don't exist in the page/document (i don't know if this
is true for sure).
hope I managed to explain it so that you could understand my point
good luck in finding a solution, or if you'll come back with more
details of what you want to achieve maybe I/we would be able to help
more.

Re: DateTimeFormat with locale
you should look at this
http://code.google.com/webtoolkit/doc/latest/DevGuideI18n.html
you'll have to addto you html pages
or if u don't like that ... you could "build" you formater by hand ...
for example DateTimeFormat.getFormat("dd/MM/ HH:mm:ss")
an have the stored in a util class
hope it helps

Re: how to set pagination or add scroll bar to the TabBar of an TabPanel
... maybe you should try adding the content in a Panel and that panel
add it to another panel (HorizontalPanel maybe for both) and "hack"
the style of the last one adding overflow:hidden
TabPanel tp = new TabPanel();
tp.setWidth("500px"); // or whatever
Widget content = ... // the realcontent
HorizontalPanel hp1 = new HorizontalPanel();
hp1.setWidth("100%");
hp1.add(content);
HorizontalPanel hp2 = new HorizontalPanel();
hp2.setWidth("100%");
hp2.getElement().getStyle().setProperty("overflow","hidden");
tp.add("tab1",hp2);
the trick will be to find out when the inner panel has bigger width
than the outer panel(or the "deck" of the tabpanel) an then show the
buttons
and on the buttons onClick() you'll do something like hp2.getElement
().setScrollLeft(incremented/decremented value)
...
hope it will be any help
good luck

Re: incubator ScrollTable
this might sound like a stupid workaround ... but can't you add an if statement or something to check if the table will have only one column ?! and for that use setColumnWidth ... i know that this is not a real answer but this is the only thing that comes into my mind without trying the real source/objects to see another "trick" hope it helps good luck On Jan 22, 2:57 am, Alexei Telles wrote: > Hi, I'm just starting using the gwt-incubator. > I need to make a table, so I am using a FixedWidthFlexTable to the > header and a FixedWidthGrid to the dataTable (content of the table). > > I have a procedure that mounts the dataTable > > The problem that I am having is: > when my dataTable have more than one column, the dataTable is ok > > I am setting the width to 100%, so my table fits my div at all. > > But when my table have only one column, I don't know why the column > width stays to short > Of course, if I use the method setColumnWidth of the FixedWidthGrid > works fine, but I use the same procedure to generate all tables of my > application, so I can't do that!!! > > I don't know if I gave a good explanation about my problem. > > I am trying to use the Firebug to discover what i am doing wrong, but > the HTML code generated is a little confused. > > Is ther anything in the FixedWidthGrid about the first column of the > table, or is there a way to I set all widths of my table like > automatic? > > I appreciate any help > > Thanks... -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Image Rotates Itself
Hi just a hint ... for example picasa if you say to rotate a image by clicking the round arrow it shows it rotated, but the image isn't really rotated picasa only makes an configuration file (hidden) that will be read every time u go there and it "says" in it that the image should be presented rotated, I saw the same thing on other picture managers to. maybe that's your problem or something similar to that. to check that this is the case, open the image with paint for example. I don't see another reason why this could happen, or maybe I'm wrong.

Re: Set the title attribute of option elements in ListBox
if you are talking about an optgroup (http://www.w3schools.com/tags/
tryit.asp?filename=tryhtml_optgroup)
I've made myself an new object that extends the default ListBox and
used instead here is the code:

import com.google.gwt.dom.client.Element;
import com.google.gwt.dom.client.OptGroupElement;

import com.google.gwt.dom.client.SelectElement;
import com.google.gwt.user.client.ui.ListBox;
/**

public class ExtendedListBox extends ListBox {
private Map groups = new HashMap();
public ExtendedListBox() {
this(false);
}
public ExtendedListBox(boolean isMultipleSelect) {
super(isMultipleSelect);
}
public ExtendedListBox(Element element) {
super(element);
}
public void insertItemToOptGroup(String group, String item, String
value) {
OptGroupElement oge = getGroup(group);
OptionElement option = Document.get().createOptionElement();
option.setText(item);
option.setValue(value);
oge.appendChild(option);
}
private OptGroupElement getGroup(String group) {
OptGroupElement oge = groups.get(group);
if (oge == null) {
insertOptGroup(group);
return getGroup(group);
} else
return oge;
}
public void insertOptGroup(String item) {
SelectElement select = getSelectElement();
OptGroupElement oge = Document.get().createOptGroupElement();
groups.put(item, oge);
oge.setLabel(item);
select.appendChild(oge);
}
private SelectElement getSelectElement() {
return getElement().cast();
}
public String getValue(int index) {
return getOptionValue(this.getElement(), index);
}
public native String getOptionValue(Element elem, int index) /*-{
return elem.options[index].value;
}-*/;
@Override
public void clear() {
groups.clear();
super.clear();
getSelectElement().setInnerHTML("");
}
}
not very fancy, but it suited my needs. hope it helps
good luck

Re: DatePicker / set a minimum date
hi 1 ideea: make a class that extends DatePicker so that you'll call the second constructor protected DatePicker(MonthSelector monthSelector, CalendarView view, CalendarModel model) for the params use new DefaultMonthSelector(), new CalendarModel() and instead of the , new DefaultCalendarView(), use a class made by the source code of that with the following changes in the inner class CellGrid (line 37) you'll have to override the isEnabled() method so that it make the check if the date is < lastDisabledDate lastDisabled could be a property in the "MyDefaultCalendarView" and also could/should be set by an method from the "MyDatePicker" also you could add a ShowRangeHandlers that on onShowRange() ... would iterate days between the start an end and do datepicker.setTransientEnabledOnDates(false,date) on each iteration or you could put the in a list and make the only once datepicker.setTransientEnabledOnDates(false,dateList) (this will call the first method so it'll be the same thing) this second method it's a lot more time/resource consuming pick your choice. ... hope this will help Good luck On Jan 4, 3:52 pm, Dariusz wrote: > Hi! > > Is there a function how to prevent people selecting a date, which is > in the past?

Re: Regional Setting
Hi there, you sould take a look at the showcase http://gwt.google.com/samples/Showcase/Showcase.html#CwNumberFormat and look around the docs for internationalization http://code.google.com/webtoolkit/doc/latest/DevGuideI18n.html if you'll use locale=... what ever you need, ... for example NumberFormat.getDecimalFormat() ... wil give the standard decimalFormat for the specified locale, NOTE: using locale you'll get extra permutations ( number of browser implementations multiplied by (the number of specified locales+1)) so if you need only a few formattings "here an there" you would better use "hand made" formater Good luck On Jan 5, 4:23 am, oks wrote: > Can I get the regional setting for number from GWT? > > By using number format, this seems to be using a fixed type of > format -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Adding a form to the RootPanel
hi
just a few tips,
to prevent the form opening in new window ... set the "target" as
you do on links (), try form.setTarget("_self"); or something
like that.
if the code that makes the form and submits it could/should be execute
several time ... you could try makeing the form an private property on
some object for your convenience, and in the moment you do the
"action" that adds the the form ... you "remove"/"clear" the old form,
and set it with the new form ...
hope it helps ... excuse my English and the lack of the details I'm in
a bit of a hurry. I'll come back with more if you'll need

Re: Clear HTML div?
you could try something like this
RootPanel.get("entries").setInnerHTML("");
the clear() method doesn't work as you expected because it comes from
HasWidgets and it removes only the Widgets that where added to the
panel with add()
if setInnerHTML(""); doesn't work as you wanted it, you could try to
make "loading" invisible
RootPanel.get("entries").getElement.getStyle().setProperty
("display","none");
Hope it helps
Good Luck

Re: How to attach a style name to a cell in a panel
Hi,
as far as I know there are no methods to access a specific cell in a
HorizontalPanel , maybe you could tweak around with getElement() or
something but I don't know
what you could do instead:
a) create an another Panel (vertical/horizontal ... doesn't matter),
put the image in it
put the styleName to this panel
put this panel in the original panel
HorizontalPanel bannerPanel = new HorizontalPanel();
bannerPanel.addStyleName("bannerPanel");
Image logo = new Image("images/Logo220x57.png");
HorizontalPanel logoWrapper = new HorizontalPanel();
logoWrapper.setWith("220px");
logoWrapper .add(logo);
logoWrapper.addStyleName("bannerLogo") ; //or you could use
setStyleName();
bannerPanel.add(logoWrapper);
or
b) use a grid instead of an HorizontalPanel
so that you have acces to the cell
Grid grid = new Grid(1,0);
grid.addStyleName("bannerPanel");
Image logo = new Image("images/Logo220x57.png");
// this could be put in a method that recives the "widget" and
you'll end up with a grid acting up more like an horizontal panel
//-
int col=grid.getColumnCount();
grid.resizeColumns(col+1);
grid.setWidget(0, col, logo);
//-
grid.getCellFormatter().addStyleName(0, col, "bannerLogo");
Anyway I hope that one of my ideas will help

Re: How to prepend?
how about this
you make an VerticalPanel
VerticalPanel vp = new VerticalPanel();
you put this in the root panel at the desired location
RootPanel.get("entries").add(vp);
and on the succes of the AsyncCallback
you put the label in that VerticalPanel at the top ( position 0)
Label response = new Label(result);
vp.insert(response,0)
the best way is to have the VerticalPanel as a private field so that
you'll have acces to it inside the AsyncCallback

Re: Unable to compile code
Hi, first of all ... where is that launch in default browser button ? i think that may be the old development mode i didn't manage to lunch it again if u updated the GWT, appengine and the eclipse plugin correctly (using eclipse update ... http://code.google.com/webtoolkit/usingeclipse.html#installing) you should after that go to the projects properties page and select the GWT 2.0 SDK instead of GWT 1.7 and finally the most important thing all the pages from an GWT app should be accesed with "?gwt.codesvr=localhost:9997" at the end so that the page should show the lastest changes in the code an also so that the page would comunicate with eclipse if that parameter is missing all that you'll see is the latest version of the compiled page as any other ordinary server I hope I managed to explain something so that you'll understand. please excuse my English as it is not my native language.

Re: Year navigation in DateBox
Hi I've choosed to create a new gadget from the original datepicker copying those classes refactoring and rewrite some because i needed an datepicker that showed 3 months instead of one. but for your case ... you should make an object looking at the code from DefaultMonthSelector, and an another class that extends DatePicker calling the constructor with the (MonthSelector monthSelector, CalendarView view, CalendarModel model) using your MonthSelector instead of the DefaultMonthSelector didn't try it but i think it should do.
