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
Engine name=Catalina defaultHost=localhost
adding the an attribute jvmRoute, with a string at your discretion but
different for every server.
Engine name=Catalina defaultHost=localhost jvmRoute=t1
Engine name=Catalina defaultHost=localhost jvmRoute=t2
...
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

You don't even need a filter or set the cookie yourself. Just make a call
to getSession(true) and it will automagically be set in the Cookies.
Typically, you will have some sort of 'initialization' RPC in your module
entry point. This is usually a good place to create the session by calling
getLocalThreadRequest().getSession(true). Once your RPC returns, go check
your cookies in the browser and you will see the jsessionid there. No need
for special filters or any of the rest of it.

Hi All,
I fixed my problem. Does anyone know how I can pass a plain,
unencoded, jsessionid with all http POST requests which the GWT client
frontend makes?
In the end I used a servlet filter in order to set a jsessionid as a
cookie for every http response my GWT application made:
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.log4j.Logger;
public class JsessionidSetter implements Filter
{
public static Logger log = Logger.getLogger(JsessionidSetter
.class);
public void init(FilterConfig arg0) throws ServletException
{
}
public void destroy()
{
}
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException
{
HttpServletResponse response = (HttpServletResponse) res;
HttpSession session =
((HttpServletRequest)req).getSession(true);
response.addCookie(new Cookie(JSESSIONID,
session.getId()));
chain.doFilter(req, res);
}
}
With supporting xml in my web.xml:
filter
filter-nameJsessionidSetter/filter-name
filter-classJsessionidSetter/filter-class
/filter
filter-mapping
filter-nameJsessionidSetter/filter-name
url-pattern/*/url-pattern
/filter-mapping
Thank you all for your comments anyway!

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 select. 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.

if you still plan to use the resources from the default theme instead of using inherits name='com.google.gwt.user.theme.standard.Standard' / use inherits name='com.google.gwt.user.theme.standard.StandardResources' / 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 nenchev.mari...@gmail.com 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

First of all, only classes in the server portion of your module have
access to the web.xml file (since browser client's don't have access

So, assuming you're in the server portion, you can just open the file
with, say, a FileInputStream. However, I've been programming servlet
for years and years and years and I've never once had to parse the
web.xml file myself. If you just want to get properties out of it
you'll likely just want to use init parameters, or, if you need to
look up servlets, you can use a named dispatcher.

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 ShowRangeHandlersDate 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: 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 inherit name=your_lib_module / you have to add the stylesheet / tag in gwt-upload usage it asks to add these in my consmer module inherits name=gwtupload.GWTUpload / stylesheet src=Upload.css / now if think about it ... you might try adding the stylesheet / 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 ashish.khives...@gmail.com wrote: Ok.

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 inherits name='com.google.gwt.user.theme.chrome.Chrome'/ use inherits name='com.google.gwt.user.theme.chrome.ChromeResource'/ 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 link type=text/css rel=stylesheet href=/module_name/gwt/ chrome/chrome.css/ 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 ahhug...@gmail.com wrote: guess: perhaps it's the order in which the css files are listed and thus loaded.

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
On Feb 21, 5:44 pm, Fabio fabio.it...@gmail.com wrote:
Hi,
First, the scenario: I designed two GWT modules (modA.gwt.xml and
modB.gwt.xml), each with its own services:
// Module A services
@RemoteServiceRelativePath(serv1)
public interface Service1OnModuleA extends RemoteService { ... }
@RemoteServiceRelativePath(serv2)
public interface Service2OnModuleA extends RemoteService { ... }
// Module B services
@RemoteServiceRelativePath(servX)
public interface ServiceXOnModuleB extends RemoteService { ... }
@RemoteServiceRelativePath(servY)
public interface ServiceYOnModuleB extends RemoteService { ... }
At the server side, service implementations were configured to serve /
modA/serv1, /modA/serv2, etc..., /modB/servX, /modB/servY.
But when trying to consume Service1OnModuleA from module B code, the
call is directed to /modB/serv1, instead of /modA/serv1. Obviously, /
modB/serv1 produces a HTTP 404 error.
By the web, I found ServiceDefTarget can be used to configure absolute
instead of relative paths:
* ((ServiceDefTarget) gwtService).setServiceEntryPoint(/some/
absolute/path);
What would be the best practices in these scenarios? The topics bellow
can help to summarize the question.
* How to design and consume inter-module services?
* What's the best way to design service URLs?
* When to use and not to use RemoteServiceRelativePath annotation?
* Is there some way to define absolute paths without having to hard-
code it everywhere via ServiceDefTaget casts?
Thanks,

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 source
path='client'/ 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

Here is the code in MyModule. This has no entrypoint class. It has one
MyForm class, one DetailsService and .gwt.xml file. (given below)
public class MyForm extends Composite {
// Code to create my form
}
MyModule.xml:
?xml version=1.0 encoding=UTF-8?
module rename-to='mymodule'
inherits name='com.google.gwt.user.User'/
source path='client'/
/module
After creating this module, I created MyModule.jar with src and class
files as described on
http://developerlife.com/tutorials/?p=229 (Although it was for
gwt1.4 and IDEA, I could use that info on gwt 2.0 and eclipse.)
I created MyModule.jar manually by copying src and class files in
required dir structure. ( I hope there is some utility of gwt itself
to create one...please let me know if any)
Code for MyModuleUsage is as given below.
public class MyModuleUsage implements EntryPoint {
public void onModuleLoad() {
// My buttons and textboxes and tables
MyForm myform = new
MyForm(); // This is from inherited
module.
RootPanel.get(MyMod).add(myform.asWidget());
// some more buttons...and their click handlers..
}
MyModuleUsage.gwt.xml
?xml version=1.0 encoding=UTF-8?
module rename-to='mymoduleusage'
inherits name='com.google.gwt.user.User'/
inherits name='com.mycompany.my.MyModule'/
inherits name='com.google.gwt.user.theme.standard.Standard'/
entry-point class='com.mycomany.your.client.MyModuleUsage'/
source path='client'/
source path='shared'/
/module
There is one more service of this project itself to handle clicks of
buttons created inside MyModuleUsage..
Now if I run MyModuleUsage then I get required output. Click on
buttons of Myform are handled by service inside MyModule and click on
buttons of MyModuleUsage are handled by service inside MyModuleUsage
as expected. This gives me a feeling that I can use MyModule as
indepedent component which I can use any other gwt project.
If I do a gwtcompilationof MyModuleUsage in eclipse then generated
no-cache.js file is of 6 kb and cache.html file is of 80 kb.
If I write code to generate same UI and service inside a single module
then generated no-cache.js file is of 10 kb and cache.html file is of
230 kb.
My question is , the way I am using multiple modules to reduce files
sizes, is it correct or no ?
Second I have never gwt compiled MyModule independently. so when
exactly it gets compiled ?
where are the compiled files for MyModule.- Hide quoted text -

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

Thanks Ashar.
So I can conclude following. Correct me if I am wrong.
1. There is no need to gwt compile included module. It gets gwt
compiled whenever user module is gwt compiled.
2. A gwt project can not be gwt compiled if it does not contain an
EntryPoint class.
GWT developers, please take a look at other part of the question.
Thanks in advance.

the MyModule that will be used in MyModuleUsage module does not need

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 source
path='client'/ tags.
when you'll GWTcompile the MyModuleUsage module GWT il put in
thatcompilationall 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

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 goca...@yahoo.com wrote: it ishttp://127.0.0.1:/ rgds, canal From: Jason Parekh jasonpar...@gmail.com 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 goca...@yahoo.com wrote: I have upgraded JDK to 1.6u18. tried the default project greetService, still the same. rgds, canal From: Jason Parekh jasonpar...@gmail.com 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?

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: 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 samko...@gmail.com wrote: Can I get the regional setting for number from GWT?

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 ShowRangeHandlersDate 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 darius...@gmail.com wrote: Hi!

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 (a /a), 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

I was just exploring using the form option, I know RPC is better in

other words, do i ever have to remove the forms I add to the root

that?

I hate it when people answer questions with other questions, but why
would you do this?
Since the form is hidden the user would have no way to submit it,
rendering it useless. If you want to communicate with the server,
simply set up and use an RPC.
Attempting to answer your questions ...
1) Yes, I would think the form would need to be added to the
RootPanel to be functional.
2) If you want to submit this form then yes, it will need to be added
(directly or indirectly) to the RootPanel. The is no memory leak in
submitting a form.

Hi,
I've been playing around with sending an invisible form using
FormPanel:
FormPanel form = new FormPanel();
form.setAction(url);
form.setMethod(FormPanel.METHOD_POST);
form.setEncoding(FormPanel.ENCODING_URLENCODED);
form.add(new Hidden(abc, xyz));
form.addSubmitCompleteHandler(new SubmitCompleteHandler() {...});
form.setVisible(false);
RootPanel.get().add(form);
I have a couple questions regarding this:
1- If I do not add the form to the RootPanel, the browser opens a new
window for the response, and the SubmitCompleteHandler event is never
fired. Is it necessary to add the form to the RootPanel to get the
correct functionality?
2- If I do add the form to the RootPanel, would I have to somehow
remove it later on? Since this code may be executed an arbitrary
number of times would that cause a problem (memory leak or something)?
Thanks,
Abdullah

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 On Dec 14, 6:06 pm, Eric edimickeast...@gmail.com wrote: Hello all, Is it possible to get a handle on a particular cell in a HorizontalPanel?

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 On Dec 14, 4:20 pm, Joe joechahh...@gmail.com wrote: Well Dennis, First, I need to know the following tag div id=entries is the main tag in your Hosted HTML file??? if so, you should be able to remove everything inside it with the RootPanel.get().clear() method.

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.
