Re: Store object in HTTP session

2008-09-14 Thread Manik Chand


Hi,

Your question is not clear.
Please write in detail.
You are asking: - How to save Object in Session?

for storing any object in session you have to access HttpSession Object.
To do that use following code.
HttpSession sessionObj = getThreadLocalRequest().getSession();


And now if you need Object at client then you should write
method in the class which extends "RemoteServiceServlet";

But that object must be serialized other wise you cant get that object.

On client side, you can use a static variable to store your data.

GWT Maps API fails on host mode

2008-09-14 Thread Einstein0970


Hi Guys,

Recently moved on Ubuntu 8.04 (64bit) and GWT 1.5.

I am using the latest gwt-maps.api and my very simple code does not
start on host mode but works perfectly when deployed under tomcat.

Here is the error I get:

Re: Store object in HTTP session

2008-09-14 Thread hezjing

Yes, that's work :-)
And I'm sorry, because I was confused :-(
What I want is how to access the session from the client code?

For example I want to add a user object into session in a login panel.
Then, retrieve the same object from the session from another panel.

Store object in HTTP session

2008-09-14 Thread hezjing

Hi
When a user successfully login, I want to store the login information into a
session.
How do we store an object in the HTTP session?

I read this Using Servlet Sessions in
GWT,
and it explained that all GWT services are implemented in classes that
extend the RemoteServiceServlet class.
>From there, we can retrieve the session from the current request.

Unfortunately, I'm following the GWT tutorial and all my services now extend
the RemoteService.
How can I retrieve the HTTP session if my service extends RemoteService?

What is the different if a service extends RemoteService
or RemoteServiceServlet?

Re: Using EasyMock in GWT Test Cases

2008-09-14 Thread Arthur Kalmenson


It's not possible to use EasyMock in GWTTestCases. EasyMock requires
Java Reflections (AFAIK), and therefore cannot be run in hosted mode.
This is why you need to architect your application in such a way that
most of your business logic lives in classes that don't use GWT
widgets and are therefore testable outside of GWTTestCase.

Regards,
Arthur Kalmenson

Re: Best solution for client-side graphing in GWT?

Hello Nathan,

I'd recommend that Google Visualization API:

There are GWT overlays in the works at the GALGWT project (http://

Re: Problem with mouse selection of suggestions in SuggestBox which is disabled in onLostFocus

2008-09-14 Thread jakob.korherr


Thanks for the explanation - I knew that already (had to do so with
Tree to change a private method).

This is a good approach. Now I just have to think how to implement it.
I will try some different things - I have some ways in mind by now. If
I find a good workaround, I will let you know!

Re: Any ideas on how to make a popup stay on top?

Sorry about the lack of xml files, that was sloopy of me.
I should have just ziped the whole project directory, but I was in a
bit of a rush.

Its really odd that the Z-indexing worked, as that was the first thing I tried
I'll have a few experiments in the full app and see if it acts the
same as the cut-down one I sent out.

Implicit in what Len has said is the fact that @EJB might work on the
server (depending on your servlet container) but _won't_ work on the
client.  As such, it's not really a GWT issue.

Re: GWT + Entity Bean

2008-09-14 Thread Len


Hi

GWT needs to be able to see the source of your entities so you need to
include them in the GWT compile. To do this create a module xml file
in the server package that contains a  statement
where entityDir is your directory containing the entity classes. Then
include this module in your main module.

SQL DateTime object to java.util.Date through JSON

2008-09-14 Thread Amit Dhingra

Hi,
I have JSON SQL DateTime objects, which I wish to convert to
java.util.Date objects, for which I have coded as below... (I am using
com.google.gwt.i18n.client.DateTimeFormat.parse for conversion)

if (...) {
.
.
.
System.out.println(sDate); //sDate is derived from a JSON obj
System.out.println(eDate); //eDate is derived from a JSON obj

Date stDate  = DateTimeFormat.getFormat("-MM-dd
HH:MM:SS").parse(sDate);
Date endDate = DateTimeFormat.getFormat("-MM-dd
HH:MM:SS").parse(eDate);

System.out.println(sDate + " & " + eDate + " Converted Dates are " +
stDate.toString() + " & " + endDate.toString());
.
.
.
}

The code above gives the following output on the console

2008-09-01 10:00:00
2008-09-01 10:30:00
2008-09-01 10:00:00 & 2008-09-01 10:30:00 Converted Dates are Mon Sep

04 10:00:00 IST 2008 & Fri Jun 04 10:00:00 IST 2010

Here I am correctly receiving the JSON object, but while converting it
into the java object using
DateTimeFormat.getFormat("-MM-dd HH:MM:SS").parse
I get wrong results, e.g.
here
2008-09-01 10:00:00
2008-09-01 10:30:00
2008-09-01 10:00:00 & 2008-09-01 10:30:00 Converted Dates are Mon Sep
01 10:00:00 IST 2008 & Tue Jun 01 10:00:00 IST 2010

The converted date is Tue Jun 01 10:00:00 IST 2010 which is incorrect.

And I see that it is just the second date which is every time wrong!!!

Am not able to get hold of the flaw here.
Where I might be going wrong???

Thanks in advance.

Thanks & Regards,
Amit

Re: I cannot run sample applications that came with GWT

2008-09-14 Thread Amit Dhingra

Found this googling...

"
Sounds like you got a 64-bit setup.

Tough luck. Won't work. When it's out, buy an OS that can interop 32-
bit and 64-bit properly, I guess. (Mac OS X Leopard).

Alternatively, complile the relevant .so (libswt-pi-gtk) yourself
using gcc, or try and find a 64-bit version. SWT is hosted somewhere
on www.eclipse.org, and you should be able to just replace the .so
file, though it MUST be the same version (3235), or it won't
interoperate with the SWT class files used by GWT. You may be able to
replace swt.jar if that file even exists with a newer version if you
can't find a 3235 64-bit version. (GWT may have integrated those files
into the main JAR file which will make your life very difficult).
If you get stuck, well, the GWT -Compiler- won't need that library so
that will still work. Just can't use hosted mode.

Re: Problem with mouse selection of suggestions in SuggestBox which is disabled in onLostFocus

You can work around that by maintaining your own version of
SuggestBox.  If you extract SuggestBox.java from gwt-user.jar and put
it in a source directory in your project that comes before
gwt-user.jar on the CLASSPATH, the GWT compiler will pick up the
extracted version instead of the version in gwt-user.jar.  You can
then modify the extracted version to suit your needs--whether that
means just removing the final keyword, or more invasive changes.  If
the "right" place to make the change is in a class other than
SuggestBox, just extract its source file instead.  If you come up with
a clean patch that looks generally useful, you could submit it for
inclusion in GWT 1.6, too.

I think that might be difficult to impossible.  Ignore GWT for a
moment and consider just what the browser is doing: clicking on the
pop-up list causes the text box to lose focus.  I'm pretty sure every
browser will fire the lost-focus event on the text box before firing
the click event on the pop-up's element.  GWT can't do anything about
the order in which the browser delivers events, and the only way it
can fire lost-focus or click events for itself is by piggy-backing on
the browser-native events.

The only idea I have that might make it possible is to complicate
SuggestBox's event handling.  When the wrapped text box fires
onLostFocus, the SuggestBox could set up a delayed call to fire its
own onLostFocus, rather than firing it directly.  In the pop-up's
onClick listener, the delayed onLostFocus would then be canceled.  The
idea is that if focus is lost because some other widget has gained it,
then the delayed onFocusLost will fire.  If, on the other hand, focus
is lost because the pop-up has gained it, then the SuggestBox as a
whole hasn't really lost focus, so the pending onFocusLost can be
sanely canceled.

The biggest problem I see with the above approach is that it would
probably re-order related onFocusLost and onFocus events.  Normally,
if widget A loses focus to widget B, A's onLostFocus fires before B's
onFocus.  If widget A is a SuggestBox modified as above, though, then
I think B will fire onFocus before A fires onFocusLost.  Ideally,
that's not a problem--event driven programmes shouldn't normally
depend on the order of events being fired, I wouldn't think--but real
life is hardly ideal.

That depends on your servlet container and not GWT. If your container

Re: slow scrolling in gwt

2008-09-14 Thread Len


Hi

Perhaps a way is not to keep all the lines in the scroll panel - only
the last 100 or so. When new lines are added after 100 remove the old
ones and if you need to, keep them in a buffer. Then when someone
scrolls back up past 100 lines you can add them back to the buffer.
In other words the scroll bar is virtual.

Just off the top of my head the Panel class is abstract and you cant

However looking again i see that is the GwtExt panel so not sure ...

[ERROR]Failed to load module com.gwt.LoginCliente". Please see the log in the development shell for details.

Hi, I'm new here, and beginners with GWT.
I am using the plugin Cypal STudio for GWT, but I can not go forward
because when I try to debug an error I always, when I declare and
initialize variables in the onModuleLoad() method or I declare outside
of the method and I initialize inside the method.
I noticed that this happens with variables declared like instance of
class imported from gwtext.
The module is this:

package com.gwt.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
import com.gwtext.client.widgets.Panel;


public class LoginCliente implements EntryPoint {

private Panel loginPanel = null;

public void onModuleLoad() {
Window.alert("ciao");

Panel formPanel = new Panel();
}}

Have you any idea?

SQL DateTime object to java.util.Date through JSON

2008-09-14 Thread Amit Dhingra


I have JSON SQL DateTime objects, which I wish to convert to
java.util.Date objects, for which I have coded as below... (I am using
com.google.gwt.i18n.client.DateTimeFormat.parse for conversion)

if (...) {
.
.
.
System.out.println(sDate); //sDate is derived from a JSON obj
System.out.println(eDate); //eDate is derived from a JSON obj

Date stDate  = DateTimeFormat.getFormat("-MM-dd
HH:MM:SS").parse(sDate);
Date endDate = DateTimeFormat.getFormat("-MM-dd
HH:MM:SS").parse(eDate);

System.out.println(sDate + " & " + eDate + " Converted Dates are " +
stDate.toString() + " & " + endDate.toString());
.
.
.

Here I am correctly receiving the JSON object, but while converting it

DateTimeFormat.getFormat("-MM-dd HH:MM:SS").parse
I get wrong results, e.g.
here
2008-09-01 10:00:00

01 10:00:00 IST 2008 & Tue Jun 01 10:00:00 IST 2010

The converted date is Tue Jun 01 10:00:00 IST 2010 which is incorrect.

And I see that it is just the second date which is every time wrong!!!

Am not able to get hold of the flaw here.
Where I might be going wrong???

Thanks in advance.

slow scrolling in gwt

2008-09-14 Thread Czarna Foka


Hi
I'm very exciting of power of gwt and I have great idea for web
application but...
One of component on my application will be group chat so I try do
performance tests and it shows me that scrolling in gwt isn't very
fast.

I did chat component as HTML inside ScrollPanel and client side
receive message from server and appends it on the end of HTML and next
step is scrolling ScrollPanel to bottom. All works fine till when HTML
contains more rows than about 2000. After this one more message cause
that scrolling take 100% power of computer for short time (less 1
second). I need optimize it, please help me maybe other component?
In gmail chat this problem not appears, why? :)

My procedure on client side looks like:

1. in loop add message(s) to StringBuilder
2. HTML.setHTML(stringbuilder.tostring) (HTML is as ScrollPanel's
Widget)
3. ScrollPanel.scrollToBottom

any suggestions?

Gwt + Openlayers + Beyond (but no so far)

2008-09-14 Thread Javier Mena


Hi,

I'm trying to use OpenLayers in Gwt, but I don't know to make
something. I want that everytime a user press a button, the
application create new panel a put a map there.

I don't know how to do it even in JS.

Currently my approach is somthing like this:

public class X {
  public onClick() {
Label x = new Label();
x.getElement().setId("mymap");
panel.add(x);
MyJsHelp.createMap("mymap");
  }
}

public class MyJsHelp {
  public native void MyJsHelp(String s) /*-{
var map = new $wnd.OpenLayers.Map("mymap");

  }-*/
}

The problem is that this code doesn't work, and I think it's because
Gwt is not creating the label before createMap is called.

If I execute the line:
   MyJsHelp.createMap("mymap");

In another event, and after creating the div, the code works.

Any ideas? Adding a listener to draw after rendering? Force Gwt to
create the label before createMap is called?

Thanks in advance,

Integrating a help system

2008-09-14 Thread [EMAIL PROTECTED]


Does anyone have a recommendation for a integrated help system that
plays nice with GWT?

Right now we are thinking of using CHM to author then exporting to
HTML.  We would still need to build hooks into our widgets to provide
the "context" piece of the context help.

Anyone have something that works better?

TIA

GWT + Entity Bean

2008-09-14 Thread Bálint Kriván

Hi!

I'm having an issue, and I hope someone can help me, because GWT looks very
great.

So I've started to make a very simple application.
I have an EJB package which contains the Session Beans and the Entity Beans.
In the WAR project I've set up the GWT:
I've created an Entry Point and a Service (RPC call) - In the implemented
RemoteServiceServlet I can use the Session Beans, which is connected to
Entity Beans. So I can make new objects to the database. It works fine.

But I would like to be able to retrieve objects as well, so I've created a
retrieve call aswell to this Service, and the returned value should be
List (Topic is my Entity Bean).
But when I want to compile my project, it says that:
[ERROR] Errors in
'file:/home/balint/NetBeansProjects/GWTForum/GWTForum-war/src/java/hu/krivan/client/service/TopicService.java'
[ERROR] Line 20: No source code is available for type hu.krivan.model.Topic;
did you forget to inherit a required module?

(This is in Line 20:
public List retrieveTopics();
)

TopicService is my interface which implements RemoteService. How can I use
my List in the UI (so I would like to build a FlexTable based on
these Topic objects.)

Very thanks for your help!

Regards,
Kriván Bálint

Re: Problem with mouse selection of suggestions in SuggestBox which is disabled in onLostFocus

2008-09-14 Thread jakob.korherr


Hmm. This would maybe help, although the SuggestBox is final and not
really designed for extending.

A great way would be changing the order of the events, so that the
click event fires before the focus event. Do you thinkt this is
possible - or even better: do you know a way to do this?

Could you subclass SuggestBox or some part of the SuggestBox system to

Hi Ian - thanks for this fast reply!

I tried your suggestion, but it has the same affect. onLostFocus and
onChange are both fired before the Item is selected.

Any other ideas?

CSS not work when using GWT4Gadgets

2008-09-14 Thread [EMAIL PROTECTED]


Hi all,

I try to build a Gadget with GWT4Gadgets. I added some basic CSS file,
but it seems to get not used. I tried to set the grids first column
color to blue with:
grid.getRowFormatter().setStyleName(0,"headerStyle);

In css I have:

.headerStyle { background-color: blue; }

In the module xml file it get "included" with:  

But it just seems to not work. Is there anything I miss ?

Thx,
Norman

Problem with mouse selection of suggestions in SuggestBox which is disabled in onLostFocus

2008-09-14 Thread jakob.korherr


I am using a SuggestBox which I enable or disable with the help of a
FocusListener on the TextBox and a flag in the SuggestOracle. This
works very fine when I select a Suggestion via keyboard. However if I
select a Suggestion via mouse click the onLostFocus method closes the
SuggestionPopup before the Suggestion is selected.

I tried to solve this bug with the help of DeferredCommand, but then I
found out that the SuggestionMenu also uses this mechanism to fire the
SelectionCommand and so the Popup still closes before the
SelectionCommand is fired.

I also thought of using a Timer with a special delay to disable the
SuggestBox in the onLostFocus method, but this is the last thing I
want to do, because of very different execution durations of the
scripts in different browsers.

Has anyone got an idea to solve this problem?

Multiple serialization policies generated

2008-09-14 Thread daniel.z


I'm using GWT 1.5.2 with hibernate4gwt 1.1b and the maven-
googlewebtoolkit2-plugin 2.0-beta20 and im currently getting multiple
differing serialization policy files (*.gwt.rpc) generated. I wondered
if there is one file per service interface as i did not find any hint
on multiple .gwt.rpc files anywhere? Is there any explenation how this
can happen?

In addition i wondered if the entries in this files are correct since
i did not see such in there before, several classes are contained
twice. one time "normal" and another prefixed by "[L" and suffixed by
";". For example:
java.lang.String, true
[Ljava.lang.String;, true

Bug? Misconfiguration? Feature?

Re: Locking assertion failure

2008-09-14 Thread Eddy


Hello,

I am not very keen on modifying a jdk module.
Can you check if GWT compilation files are identical before and after
the change?
after all if it doesn't affect the compilation phase is not a big deal
Thank You
Edoardo

Re: My app crashes Safari on reload... how do I find the problem?

2008-09-14 Thread Nevin Freeman


Well the problem is a bit different than I thought. I'm not sure if it
is somehow specific to my system, but it's certainly not my specific
application. When I make a new GWT app with the applicationCreator
script (no eclipse project), compile it, open the host html page in
Safari (Version 3.1.2 (5525.20.1)) and hit the refresh button, it
quits. This happens with both versions of gwt-mac that I have (1.5.0
and 1.5.2).

I've filed an issue, and attached the crash report.
