How to sing events on the mark up element
Hi,
I want to access the text box written in HTML from GWT on the basis of
element ID. I am able to get this elemt in GWT and also show that. Even I am
able to change the text of the text box but I am not able to add the events
to the element. How to add the event. I have written some bit of code but
not able to sink the event.
I have extended the text box to add the element
-
Public class MarkupTextBox extends TextBox{
Public MarkupTextBox(String markupTextboxID) {
This(DOM.getElementById(markupTextboxID));
}
Protected MarkupTextBox(Element element) {
Super(element);
}
}
-
And then adding listener to it
-
--
Final MarkupTextBox box = new MarkupTextBox(poctext);
Box.setText(Hi how are you);
Box.addClickListener(new ClickListener(){
Public void onClick(Widget sender) {
}});
Box.addChangeListener(new ChangeListener(){
Public void onChange(Widget sender) {
Box.setText(Hi how are you);
}});
-
May be I making some mistake. Please suggest me without the suggestion of
using the
Third party lib like GWTTiger.
Warm Regards,
Vaibhav Saxena

Re: Connecting to database with eclipse
Hi there,
Ok lets take it step by step.
Can you show us your client side RPC interface classes.
You should have something like the following:
---
package com.company.client.rpc;
import java.util.List;
import com.company.client.dto.PupilDTO;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath(teachers)
public interface TeacherService extends RemoteService
{
public ListPupilDTO getPupils(Integer teacherId);
}
-
package com.company.client.rpc;
import java.util.List;
import com.company.client.dto.PupilDTO;
import com.google.gwt.user.client.rpc.AsyncCallback;
public interface TeacherServiceAsync
{
public void getPupils(Integer teacherId,
AsyncCallbackListPupilDTO callback);
}
Take not of the @RemoteServiceRelativePath(teachers) thats very
important. Do you have this?

Re: IE doesnt show my progress bar when the data loads in to my Grid
You can't start antother thread from javascript. And though it's a singlethreaded environment your animation isn't moving probably because browser is busy with filling the data.

SuggestBox focuslistener problem with Chrome
Hi all,
I am using a SuggestBox but i have added a prompt on it.
It shows Enter a number when focus is not on SuggestBox and when
focus is set on suggestbox i set the text to using focuslistner.
This works fine on all other browsers but when i try it on Chrome i
have to click on suggestBox and then drag the mouse and then only the
suggest box text is set to .
Here is the code
FocusListener OnFieldFocus = new FocusListener()
{
public void onFocus( Widget sender)
{
SuggestBox sb = (SuggestBox)sender;
if (sb != null)
{
if ( sb.getText().equals(Enter a number)))
sb.setText();
}
}
public void onLostFocus(Widget sender)
{
SuggestBox sb = (SuggestBox)sender;
if (sb != null)
{
if (sb.getText().trim().length() == 0)

sb.setText(Enter a number));

}

};

Hi guys,
I am using GWT's Treepanel and I need to set different icons for my

I tried using TreeNode.setIconCls(String) but it doesn't seem to work.
My style names are contained in a CSS file and I am also using these
style names
in setting the icons of menu items (using setIconCls()) and they work
(the icons appear on the menu items).
Below are some code snippets:
Java:
TreeNode configNode = new TreeNode(+ New);
configNode.setUserObject(-1L);
configNode.setIconCls(new);
parentNode.appendChild(configNode);
CSS:
.new {background-image:url(../images/payroll/new.png);}
I don't know what I'm missing here -- the codes I've seen in the GWT
demo are using the same implementation (setIconCls).
Thank you in advance. :)

You could violate the GPL (or any license) if you incorporated code from some other project into GWT. Suppose I released a project under the GPL and somebody took some code from my project and got it incorporated into GWT. GWT would probably be unwittingly violating the GPL because it would be a derivative work of my project and it's not being distributed under the terms of the GPL. I don't think that was the scenario originally presented in this thread, though, and I don't think there's any reason to believe that GWT contains contraband code.

Hi everyone,
i am trying to disable a few tabs in my TabBar since there is no
content in some cases. Therefor i disabled those tabs due to adding a
TabListener with the Method onBeforeTabSelected which returns false if
the tabIndex fits. (hint from this
thread:http://groups.google.com/group/Google-Web-Toolkit/browse_thread/threa...)
. It works fine and nothing happens if you try to click on the tab.
Now i want those disabled tabs to look different than active or
selected tabs.
Example CSS file:
.MainBar .gwt-TabBar {
background-color: #22;
}
.MainBar .gwt-TabBarItem {
font-weight: bold;
cursor: pointer;
background-color: red;
}
.MainBar .gwt-TabBarItem-selected {
font-weight: bolder;
cursor: default;
background-color: green;
}
.MainBar .gwt-TabBarItem-disabled {
color: grey;
font-style: italic;
background-color: yellow;
cursor: default;
}
It works for the active and selected tabs, but i think disabled tabs
are not supported in GWT 1.5.3 that's why i have to set the style on
my own (since i only managed to disable them), but i don't know how to
access a single tab. Any suggestions? If there is a better way to
disable tabs and change the style let me know! I think with GWT 1.6 it
is possible to enable/disable single tabs, but i would like to work
with 1.5.3 until 1.6 has the status of a new official release.
Thanks a lot in advance,

When I click the login button I need to pass the http://localhost:/examples.Welcome/Welcome.html. url . am i right? If it is this case, do I need to create this one as the entry point?

I don't think that you can satisfy both requirements. As far as I know, when you navigate to another page, even if that page references the same application, a new instance of the application will load on that page. I can think of the following alternatives for you: 1.) Only use one URL, as you've already found. 2.) Use two separate GWT applications (and thus get two URLs). You can do this *and* share information between them, if you like. Essentially, your login application, on successful login, would move to another page, say welcome.jsp (using Window.Location.assign, for instance). welcome.jsp would contain another GWT application. This welcome.jsp GWT application either can: a.) Do RPC to the server in order to get information about the user (since the user now has a session on the server). b.) Have the server fill in any necessary information via JSP templating before being returned to the user.

You *can* get at the individual tabs using the DOM, but it will be dependent on the structure of the tab panel and therefore would break if that gets changed. If I were doing it, I'd just set the tab text as HTML with the style included - disabled or not as required.

Re: Google App Engine GWT
No Threads? A Java application cannot create a new java.lang.ThreadGroup nor a new java.lang.Thread. These restrictions also apply to JRE classes that make use of threads. For example, an application cannot create a new java.util.concurrent.ThreadPoolExecutor, or a java.util.Timer. An application can perform operations against the current thread, such asThread.currentThread().dumpStack(). What about runnable? Runnable is implemented by class Thread. Runnable provides the means for a class to be active while not subclassing Thread But...still, I think that it wouldn't work. Can anyone please confirm this?

Re: Using DAO pattern in a GWT project
You can use DAO pattern to wrap EntityManager using Dreamsource ORM. You can download it from http://dreamsource-orm.googlecode.com/files/dreamsource2_0_0_04062009_GWT_src.jar, create an source folder like dreamsource and extract source files from it into dreamsource source folder. Please check more info from http://www.leeonsoft.com. Dreamsource ORM will make your GWT application to be developed easier and faster. I will create an GWT example based on the Mail included with GWT distribution. Jim Xie On Apr 8, 2:27 am, Neo deepak.krv2...@gmail.com wrote: Hi, Can i use the DAO pattern in a GWT project.

Proposal for a compiler optimization parameter allowing a cross-module communication scheme.
===
Context information
===
In order to handle server push events, I am using a pattern
described and used in multiple places: a getEvents() RPC method waits
for up to 30 seconds but returns as soon as an event is received.
The issue is that this pattern eats a browser connection, so that if
two GWT modules (loaded on a given page) do register to server events,
the 2 allowed connections are wasted.
Hence my desire to have a central events receiver/router in the
browser and possibly several GWT modules listening to that router.
===
In the router:
===
public class ServerEventsRouter
{
public static void addServerEventsListener( ServerEventListener
listener )
{
// register the listener in a collection...
}
...
private static native void createRegisteringFunction() /*-{
$wnd.addServerEventsListener =
@com.foo.gwt.ServerEventsRouter::addServerEventsListener(Lcom/foo/gwt/
events/ServerEventListener;);
}-*/;
...
}
The createRegisteringFunction() needs to be called first somehow...
===
And then, in the client listener:
===
private native void registerServerEventsListener
( ServerEventListener listener )/*-{
$wnd.addServerEventsListener ( listener );
}-*/;
and
registerServerEventsListener( new ServerEventListener() {
public void onServerEvent( ServerEvent event ) {
GWT.log( Received event, null );
});
===
The Issue(s)
===
However, as you might expect, this doesn't work. Well, it works for
'hello world' type of functions which not not require parameters...
but the ServerEventListener parameter is not marshalled properly.
A. In WEB mode
The ServerEventListener interface is not implemented by any class in
the router module, so that the dispatching function is optimized from:
for ( ServerEvent event : events ) {
for ( ServerEventListener listener : listeners ) {
listener.onServerEvent( event );
}
}
into something like:
for (event$iterator = events.iterator(); event$iterator.hasNext
();) {
dynamicCast(event$iterator.next_0(), 11);
for (listener$iterator = $AbstractList$IteratorImpl(new
AbstractList$IteratorImpl(), this$static.m_listeners); listener
$iterator.i listener$iterator.this$0.size_0();) {
throwClassCastExceptionUnlessNull($next_1(listener
$iterator));
null.nullMethod();
}
}
B. In HOSTED mode
Presumably in order to match the behaviour of the WEB mode, the
classes in the two modules are loaded from two different class
loaders, so that the implementations of the ServerEventListener are
not seen as such in the router module and any assignment generates a
class cast exception.
===
My proposal
===
Instruct the compiler not to optimize out sub-classes of a specified
type (here ServerEventListener), and have these classes loaded from a
common upstream (i.e. more global) class loader in Hosted Mode.

Re: Asynchronous communication from server to client
petrus schrieb: Is there a possibility in GWT to communicate asynchronously from server to client? The term used in general for that is Server Push. A technique for that is called Comet, so if you search Comet GWT with the search engine of your choice, you should come up with a couple of results. The only solution which I've found is to use Timer as it's showed there http://www.gwtapps.com/doc/html/com.google.gwt.user.client.Timer.html , but then calls will be synchronous. What solution do you recommend? Calls in GWT are always synchronously, independent of the way they are initiated. But if you solve it using a Timer you should set a flag if a request is already in progress to make sure that only one requests happen at the same time.

On Apr 1, 12:02 pm, -Lord-67 -lord...@web.de wrote:
Hi everyone,
i am trying to disable a few tabs in my TabBar since there is no
content in some cases. Therefor i disabled those tabs due to adding a
TabListener with the Method onBeforeTabSelected which returns false if
the tabIndex fits. (hint from this
thread:http://groups.google.com/group/Google-Web-Toolkit/browse_thread/threa...)
. It works fine and nothing happens if you try to click on the tab.
Now i want those disabled tabs to look different than active or
selected tabs.
Example CSS file:
.MainBar .gwt-TabBar {
background-color: #22;
}
.MainBar .gwt-TabBarItem {
font-weight: bold;
cursor: pointer;
background-color: red;
}
.MainBar .gwt-TabBarItem-selected {
font-weight: bolder;
cursor: default;
background-color: green;
}
.MainBar .gwt-TabBarItem-disabled {
color: grey;
font-style: italic;
background-color: yellow;
cursor: default;
}
It works for the active and selected tabs, but i think disabled tabs
are not supported in GWT 1.5.3 that's why i have to set the style on
my own (since i only managed to disable them), but i don't know how to
access a single tab. Any suggestions? If there is a better way to
disable tabs and change the style let me know! I think with GWT 1.6 it
is possible to enable/disable single tabs, but i would like to work
with 1.5.3 until 1.6 has the status of a new official release.
Thanks a lot in advance,

Can't compile with new 1.6 project
Hello, I was using 1.5 and Eclipse for my project and it worked fine (with some home made compiled script). As I wanted to upgrade to the last version, I installed the new Eclipse gwt plugin and created a new project. I think I succeed to import my 5 or 6 modules of my old project, as they are recognized while I want to use the compile tool from the gwt eclipse plugin. But... I can't compile, I've got an error with the very first module, something like : Compiling module fr..client.accueil Computing all possible rebind results for 'fr..client.site.tab.accueil.HomeTabEntryPoint' Rebinding fr..client.site.tab.accueil.HomeTabEntryPoint Checking rule generate-with class='com.google.gwt.user.rebind.ui.ImageBundleGenerator'/ [ERROR] Unable to find type 'fr..client.site.tab.accueil.HomeTabEntryPoint' [ERROR] Hint: Previous compiler errors may have made this type unavailable [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly I only inherit the com.google.gwt.user.User module, I verified that 'fr..client.site.tab.accueil.HomeTabEntryPoint' is right too (and in the directory src, which is the source folder), and gwt-user and gwt-dev are part of my librairies in my build path.

Re: opening new page
In one GWT application/page, you could show the log in widget, check via Ajax if the details are valid, and if so, display the widget for the second page. There is no need for 2 pages or anything complicated. Ian http://examples.roughian.com 2009/4/8 bhanu baksh...@gmail.com This is the way only I also thought. 1. One url that is the main url for Login. And different modules for different pages. right? so I will get the different urls corresponding to different pages. for example. Login page. that is the entry point for the application. http://localhost:/examples.Login/Login.html Welcome.jsp that is the different module which I have to create. http://localhost:/examples.Welcome/Welcome.html . When I click the login button I need to pass the http://localhost:/examples.Welcome/Welcome.html. url . am i right? If it is this case, do I need to create this one as the entry point? Or only One entry point and remaining everything I can do in the Composite right? Please correct me If I am wrong.

I don't think that you can satisfy both requirements. As far as I know, when you navigate to another page, even if that page references the same application, a new instance of the application will load on that page. I can think of the following alternatives for you: 1.) Only use one URL, as you've already found. 2.) Use two separate GWT applications (and thus get two URLs). You can do this *and* share information between them, if you like. Essentially, your login application, on successful login, would move to another page, say welcome.jsp (using Window.Location.assign, for instance). welcome.jsp would contain another GWT application. This welcome.jsp GWT application either can: a.) Do RPC to the server in order to get information about the user (since the user now has a session on the server). b.) Have the server fill in any necessary information via JSP templating before being returned to the user.

Large GWT-application on mobile phones
Hello, today I tried to run my main GWT-application (administrative backend of a server-application) on an iPhone/iPod touch and a G1 with Android. At the moment the application is still compiled using GWT 1.4.60, so some issues might already be fixed with later versions. The following things I saw trying that: Android: - The browser coming with G1 is not able to do HTTP Basic Authentication (WTF?) - RPC-calls using serializable classes lead to ArrayIndex- OutOfBoundsExceptions on the server-side when using serialized classes (seems to work with GWT 1.5.3 if I followed threads here correctly). Mobile Safari: - Safari on an iPod touch 2G is showing the application after some while and crashes after doing some RPC-calls. - Safari on an iPhone 2G shows the application but instead of crashing, the browser fails to do RPC-calls after a while. I think the problems with Safari are a result of the size of the application (HTML-file) of more than 1MB. The application is in my eyes simply running out of memory. Before starting a migration from 1.4.60 to 1.5, should I wait for 1.6 and use LazyPanel or is there no effect at all if I have a huge HTML-file anyway? Or is there now a way to modularize the application, allowing to download parts of the application on demand instead of one big HTML-file being loaded at startup)?

Asynchronous communication from server to client
Hello, Is there a possibility in GWT to communicate asynchronously from server to client? The only solution which I've found is to use Timer as it's showed there http://www.gwtapps.com/doc/html/com.google.gwt.user.client.Timer.html , but then calls will be synchronous.

May be I making some mistake.
Your widget isn't attached, so events are actually not sunk. Why not
just use TextBox.wrap(DOM.getElementById(markupTextboxID)) instead of
building your own MarkupTextBox?

Re: Just getting started with GWT: how to wrap a native Java library?
Hey Jake,
I've never used the SWT Canvas, but if it's anything like the canvas
tag, you might want to check out the GWTCanvas in the incubator:

Also, Vitali, there's a GWT library for accessing gears:

ImageBundle too wide to display in IE7 under Vista
I recently encountered an issue where the contents of an ImageBundle were not being displayed at all, but only under Vista and IE7. Using XP with IE6, IE7, FireFox 2, FireFox 3 the contents of the ImageBundle displayed with no problems. There are second hand reports that it worked under Vista and IE8, but I have not seen it myself. I ruled out file size as the limiting factor sense I have other ImageBundles that worked properly, yet their file size was larger than the offending ImageBundle. After some experimenting it APPEARS that IE7 under Vista imposes a limit of 2048 pixels for the width of a PNG that is being displayed using the AlphaImageLoader Filter. As soon as the ImageBundle width exceeds 2048 pixels, it fails to appear. The obvious work around was to break up the ImageBundle to reduce it's width. Has anybody else encountered this? Is this something that I should have already known about? Thanks, Mark McCall --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: CSS Style for single tabs of a TabBar
Hi, Don't use the DOM - Google might change the structure, that's what would break it. There are two possibilities: 1) Add HTML as the tab title When the enabled/disabled change happens, get it back and change the style class in the html string you get back and replace it (a simple replaceAll() would do). 2) Add a Label widget as the tab title Also add that label to an ArrayList (because there is no way to get it back from the tab, so you have to do it this way) When the enabled/disabled change happens, get the label from the ArrayList and do a setStyle() on it. The first way is kludgier, but simpler :-) Ian http://examples.roughian.com 2009/4/8 -Lord-67 -lord...@web.de @Ian Bambury: Thanks, i will try it with DOM or else if that doesn't work the second way with html, just not sure if i will be able to do that on my own since i am not that experienced :-).

some while and crashes after doing some RPC-calls.
- Safari on an iPhone 2G shows the application but instead
of crashing, the browser fails to do RPC-calls after a while.
Do you see these problems on the desktop version of Safari?
No, the application is running smoothly there.
The iPhone
desktop versions are pretty much identical in the backend. What do
you mean by crashes?
When working with the application it suddenly vanishes in the same
way it do when you press the Main-button. I never saw this behavior
on other pages, so I assume that it's killed by the operating system
because there is not enough memory and Safari wasn't able to free
up enough ressources after being told so by the system (which lead
to the kill of the application).
So crashing might not be the correct term here but the user-
experience is the same ;-)
[Splitting GWT-application to reduce memory-consumption]
Build from trunk use GWT.runAsync
http://code.google.com/p/google-web-toolkit/wiki/CodeSplitting.
Looks good (meaning that I still can skip 1.5 and can go from
1.4.60 to 1.6 directly).
Two questions that I don't find answered in the page you linked:
1. My application is already modularized, every page allowing
the administration of one particular service is a class
derived from a superclass AbstractServicePanel. When clicking
on an entry in the list of services, a method is called that
is evaluating the panel to be initialized:
AbstractServicePanel panel = null;
try{
if (status.handlingName.equals(AS2Service)){
panel = new As2ServicePanel();
}
else if (status.handlingName.equals(LogService)){
panel = new LogServicePanel();
}
else if (status.handlingName.equals(authplain)){
panel = new AuthServicePanel();
}
else if (status.handlingName.equals(commlogplain)){
panel = new CommunicationLogServicePanel();
}
[etc]
else if (status.handlingName.equals(AdminService)){
panel = new AdminServicePanel();
}
}
catch(Throwable t){
callback.onFailure(t);
return;
}
if (panel == null){
panel = new UnimplementedPanel(status);
}
callback.onSuccess(panel);
The callback removes a previously shown panel and adds the new
one. Is it enough to put the whole if-cascade into one GWT.runAsync
or do I have to do it for every if-statement if I want to let GWT
perform a deferred loading for each panel?
2. Is it possible to unload loaded parts? Otherwise I might be
able to run the application in the beginning but the longer the
application is used (i.e. the more panels are loaded and initialized),
the higher the likelyhood of running out of ressources will be.
You may also want to ensure
that you aren't leaving cycles in your references, thereby preventing
garbage collection (i.e. when you remove a widget, remove it's listeners
as well).
Is there a link to the GWT-documentation where this problem is
explained further? If I have a Panel, containing a button and
I add a ClickListener to that Button, do I really have to remove
that ClickListenner from the Button before removing the Panel?
Since you're also dealing with the mobile space, you may want
to make sure that when you hide a composite, you actually remove it from
the page then recreate it as necessary if it gets added back (unless
it's really expensive).
I've got quite complex Dialog-boxes. How can I remove a Dialog-box?
At the moment I'm only calling hide().
Thanks and regards, Lothar

That seems strange unlikely given that it's Chrome (or at least some

I don't have Chrome on the desktop (I don't agree with the terms of

Would installing it in a temporary VM be ok? Then you can just wipe the VM
afterwards.
The phone was updated about
one month ago. The phone's message is quite clear:

(The site's authentication-scheme is not supported)
The server's response-header looks OK to me:

No, the application is running smoothly there.
Are you sure that the RPC calls stop that your app isn't crashing? Try
this in your onModuleLoad:
new Timer() {
public void run() {
rpcServiceAsync.doRpcHeartbeat(System.currentTimeMillis(), new
AsyncCallbackVoid() {public void onFailure(Throwable cause){} public void
onSuccess(Void result){}});
}
}.scheduleRepeating(5000);
where doRpcHeartbeat is an RPC invocation where you just log the timestamp
on the server or something. That way you can be sure that you can tell if
suddenly RPC stops working (by the way, there's a limit to how many
concurrent outstanding AJAX calls you can make - could you be hitting this
limit?).
The iPhone

Are your phones jailbroken? If so, there might be some performance monitors
you can run (at the very least you have top) to get a sense of why Safari
crashes (does Apple provide developer tools for determining why Safari
unloads the page?)
So crashing might not be the correct term here but the user-

Re: Proposal for a compiler optimization parameter allowing a cross-module communication scheme.
Seems like your pattern is easily solved (I didn't look at your compiler
suggestion, so this isn't a comment about that). Have your clients send a
timestamp in the RPC to the server.
The server then takes the highest timestamp tells the client that it
doesn't need to listen to notifications instead listen to some other
module.
Then for your central communication, you can use JSNI to transfer data
between modules, or, better yet, have 1 module that inherits the other
modules can then provide them with a ServerEventsRouter to use.
On Wed, Apr 8, 2009 at 6:04 AM, Yann jan.vorw...@googlemail.com wrote:
===
Context information
===
In order to handle server push events, I am using a pattern
described and used in multiple places: a getEvents() RPC method waits
for up to 30 seconds but returns as soon as an event is received.
The issue is that this pattern eats a browser connection, so that if
two GWT modules (loaded on a given page) do register to server events,
the 2 allowed connections are wasted.
Hence my desire to have a central events receiver/router in the
browser and possibly several GWT modules listening to that router.
===
In the router:
===
public class ServerEventsRouter
{
public static void addServerEventsListener( ServerEventListener
listener )
{
// register the listener in a collection...
}
...
private static native void createRegisteringFunction() /*-{
$wnd.addServerEventsListener =
@com.foo.gwt.ServerEventsRouter::addServerEventsListener(Lcom/foo/gwt/
events/ServerEventListener;);
}-*/;
...
}
The createRegisteringFunction() needs to be called first somehow...
===
And then, in the client listener:
===
private native void registerServerEventsListener
( ServerEventListener listener )/*-{
$wnd.addServerEventsListener ( listener );
}-*/;
and
registerServerEventsListener( new ServerEventListener() {
public void onServerEvent( ServerEvent event ) {
GWT.log( Received event, null );
});
===
The Issue(s)
===
However, as you might expect, this doesn't work. Well, it works for
'hello world' type of functions which not not require parameters...
but the ServerEventListener parameter is not marshalled properly.
A. In WEB mode
The ServerEventListener interface is not implemented by any class in
the router module, so that the dispatching function is optimized from:
for ( ServerEvent event : events ) {
for ( ServerEventListener listener : listeners ) {
listener.onServerEvent( event );
}
}
into something like:
for (event$iterator = events.iterator(); event$iterator.hasNext
();) {
dynamicCast(event$iterator.next_0(), 11);
for (listener$iterator = $AbstractList$IteratorImpl(new
AbstractList$IteratorImpl(), this$static.m_listeners); listener
$iterator.i listener$iterator.this$0.size_0();) {
throwClassCastExceptionUnlessNull($next_1(listener
$iterator));
null.nullMethod();
}
}
B. In HOSTED mode
Presumably in order to match the behaviour of the WEB mode, the
classes in the two modules are loaded from two different class
loaders, so that the implementations of the ServerEventListener are
not seen as such in the router module and any assignment generates a
class cast exception.
===
My proposal
===
Instruct the compiler not to optimize out sub-classes of a specified
type (here ServerEventListener), and have these classes loaded from a
common upstream (i.e. more global) class loader in Hosted Mode.

Re: Connecting to database with eclipse
Are you using GWT 1.4 or 1.5?
If you are using 1.5 add the line:
@RemoteServiceRelativePath(teachers)
in the same place as where I have mine - replace teachers with
whatever path you want for your servlet.
next thing is how to call the servlet using RPC this should be done
like so:
TeacherServiceAsync teacherService = (TeacherServiceAsync) GWT.create
(TeacherService.class);
teacherService.getPupils(teacherId, new AsyncCallbackListPupilDTO
()
{
public void onFailure(Throwable caught)
{
// TODO Auto-generated method stub
}
public void onSuccess(ListPupilDTO result)
{
// TODO Do something with the result
}
});
You can see how my client side code matches up now - is this making
sense so far and do you have something similar? This is how GWT RPC
should be implemented client side.

Re: Connecting to database with eclipse
Next you need to have server side class something like this:
-
package com.company.server.gwt;
public class TeacherServiceImpl extends RemoteServiceServlet
implements TeacherService
{
private static final long serialVersionUID = 1L;
public ListPupilDTO getPupils(Integer teacherId)
{
ListPupilDTO results = performYourServerSideAction();
return results;
}
}
---
Then in your GWT.xml file you need to link the server to the client
with servlet mappings like so:
servlet path=/teachers
class=com.company.server.gwt.TeacherServiceImpl/
Notice I use /teachers to map to my server side class.
Thats pretty much it. Your DB code that you have already shown us
should go on the server side either in your ServiceImpl class or
another server side bean (preferred)

Eclipse Plugin Compile Button Stack Overflow
Just installed the Google plugin for Eclipse, and hit the Compile button on my project. It gave me a stack overflow error. Prior to using the plugin, I'd compile by hitting the Compile button in the hosted mode browser. In the Run/Debug Eclipse configuration, I have -Xss4k -Xmx256M Compiles worked fine with those flags and the Compile button from hosted mode. How do I set the Xss flag for use by the Compile button in the eclipse toolbar? I tried putting it in the Advanced section, but this just informed me it wasn't an appropriate gwt compiler option. This isn't stopping me from doing anything, as I can still compile from hosted mode, just curious how to set it up. I checked the plugin faq, but couldn't find anything there. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: debug freeze
Correct, the hosted mode log showed the creation of various widgets but there was no null pointer messages. I had sprinkled Window.alert() messages all over the place to narrow down the issue and eventually found the line. Starring at the line made no sense because it was a rational statement... except that I had not initialized the object. On a whim I stuck a try/catch block around the line and it shouted out that the object was null. go figure.

Trying to use server in another module
Hello all, I'm facing my first GWT development. I had the idea of developing a project with a module which I have called x.gwtlogin. The server of this module can perform queries on a LDAP server. My idea is to have an instance of this module running in the application server and use its server from any other GWT application I develop. Let's say one of these applications is x.dt. I have copied all x.gwtlogin.client classes that implement the server's interfance in this application, so now I have two client packages in the project: x.dt.client x.gwtlogin.client The problem is that when debugging in hosted mode wherever I try to use a x.gwtlogin.client.Class in a x.dt.client.Class, I get the following error: [ERROR] Line 20: No source code is available for type x.gwtlogin.client.Class; did you forget to inherit a required module? I suppose the problem is that GWT is not compiling and including the classes in x.gwtlogin.client when building x.dt.client. What can I do?. Is what I intend to do possible at all?.

Re: How to create CSS style for disabled buttons
I have the same problem with textboxes: it does not work on IE6, selectors are not supported. You need to define a specific class for that style (disabled) and add that style to your component when it is disabled. I am currently looking for a better way to do that. One solution would consist to extend the component and manage a disabled dependent style by overriding the setEnabled function. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Connecting to database with eclipse

I've made the corrections and it works now.
I'm wondering, how should i call a service properly? In this piece of

Re: CSS Style for single tabs of a TabBar
Hi, i didn't find out how to do it with DOM and i won't try any more (thanks for this hint). Instead i was able to change the single tabs due to setting the HTML as you told, but i wasn't able to set a CSS style The first solution sounds a bit like quick and dirty. I think i will try the second one which sounds good to me. Pretty sophisticated work. Thanks! Greetings, -Lord-67 On Apr 8, 3:13 pm, Ian Bambury ianbamb...@gmail.com wrote: Hi, Don't use the DOM - Google might change the structure, that's what would break it. There are two possibilities: 1) Add HTML as the tab title When the enabled/disabled change happens, get it back and change the style class in the html string you get back and replace it (a simple replaceAll() would do). 2) Add a Label widget as the tab title Also add that label to an ArrayList (because there is no way to get it back from the tab, so you have to do it this way) When the enabled/disabled change happens, get the label from the ArrayList and do a setStyle() on it. The first way is kludgier, but simpler :-) Ian http://examples.roughian.com 2009/4/8 -Lord-67 -lord...@web.de @Ian Bambury: Thanks, i will try it with DOM or else if that doesn't work the second way with html, just not sure if i will be able to do that on my own since i am not that experienced :-).

Re: Connecting to database with eclipse
Can you confirm (server side) that the array of objects isn't null?
If so this sounds like GWT might not be able to handle objects of type
Forum.
GWT can only handle objects declared under the client side packages
and wont be able to handle any database POJO object declared at server
level.
For some more background info:
http://www.dotnetguru2.org/bmarchesson/index.php?p=786more=1c=1tb=1pb=1
You'll need to create some form of client side DTO object
alternatively if you can move over to using Hibernate you can use a
package called Hibernate4GWT
I've also compiled a tutorial on this at:
http://eggsylife.blogspot.com/2007/11/hibernate-spring-google-web-toolkit.html
That is part two of the tutorial with my DTO objects.

Provide support for NavigableMap/NavigableSet implementation?
Hi, I was wondering if anyone has tried adding NavigableMap/ NavigableSet (From JDK 1.6), support for use in GWT? Using the JRE emulation mechanism (super-source), it should be possible to add the required interfaces then update GWT's TreeMap, to implement NavigableMap. I've gotten part-way through this with a SkipList but implementing all of the extra methods to return sub-views is too much work. I realized it might be simpler to just extend Google's version of TreeMap to add the Navigable code. Any thoughts? I searched a bit, but nothing yet. My main use case is finding a point in a sorted set, then efficiently iterating in either direction. I've cooked up my own SkipListMap implementation but I feel like I'm reinventing the wheel if I create my own navigable interface, but the NavigableMap dictates a lot of functionality I don't have time to implement myself either. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Android Compatibility Isses with GWT (UI based, not RPC)
Hey guys, Little stream of conciseness here, sorry if this is a bit long/ disjoined. I was wondering if anyone had done any work with GWT and the Android Browser. While I'm getting basic functionality to work, the general speed, responsiveness and user experience seem very sluggish and, well, sorta bad. Another issue I'm having is locating a group to go to for support, examples and help. While I'm interested in GWT with Android, it seems that Android Developers Group is really only interested in native apps. Where to go for Browser specific help? Anyways, some of the particulars I've run into: What group to go to? 1. Issues Controlling the viewport: No matter what I do, I can't seem to get proper control of the viewport. Editing the meta data, overflow CSS properties, insuring that the window's objects are small, etc. I'm continually getting white space borders and stuff like that. This causes weird finger behavior, especially allowing the user to browse into the white space. 2. HTML5/Gears Wrappers: I was wondering if the Gears API has an implementation to support HTML5 storage/cache issues in case of a non- gears enabled client. If not, is there a library anywhere that supports the encapsulation for GWT? 3. MouseListeners: The OS seems to swallow up the MouseUp event in order to do detection of scroll/drag type stuff. I guess I understand why it does it for the drag type thing, but it never fires MouseUp even after the drag is done. Ehh... fair enough, I guess. 4. Focus Panel ClickListeners: When I click a focus panel, a orange circle shows up in the upper/left corner with what seems like a cursor in it? (http://i243.photobucket.com/albums/ff2/gte619n/ selectBubble.png) Also seems like a non-trivial delay between the press and then a following action. Makes the app seem especially sluggish. 5. Image Loading/Display: Seems really slow. Even when doing background repositioning to flip sprites. Additionally, the images don't seem to load in any fixed order and method. Also seems to hang when loading images (http://i243.photobucket.com/albums/ff2/gte619n/ selectBubble.png) I've attempted to get around this by doing Prefetch and such, but nothing seems to work. Seems like it needs to talk itself into refreshing the screen after loading finishes (even in localhost in the emulator) 6. Visibility hide/show: Very sluggish in general. 7. Scroll inside divs: Flat out doesn't support this. I guess the Cupcake release, bringing the browser up to Nov 2008 Webkit, should fix this but I still don't have any visibility into that release. Has anyone compiled some best practices to use when building an Application for Android? Maybe even some widgets or JSNI breakouts to better manage the behavior and performance of the app? Thanks!

Re: Eclipse Plugin Compile Button Stack Overflow

Prior to using the plugin, I'd compile by hitting the Compile button in the hosted mode browser. In the Run/Debug Eclipse configuration, I have -Xss4k -Xmx256M Compiles worked fine with those flags and the Compile button from hosted mode. How do I set the Xss flag for use by the Compile button in the eclipse toolbar? I tried putting it in the Advanced section, but this just informed me it wasn't an appropriate gwt compiler option. The advanced section just passes the arguments to the GWT compiler. There is no way to bump those up right now. We'll need to include this in the next update of the plugin (still no timeframe on that). This isn't stopping me from doing anything, as I can still compile from hosted mode, just curious how to set it up. I checked the plugin faq, but couldn't find anything there. -- Miguel --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 1.5.3 upgrade problem with RPC
Hi, I never used GWT 1.4. I started from GWT 1.5.3 directly. But I get the same exception. What would be the cause for that? Do you know anything about this?

Re: Trying to use server in another module
Sorry, too fast. I made it work including x.gwtlogin in x.dt as a module with no entry point. I didn't need to copy the server classes, so I have a single server as I wanted. On 8 abr, 17:28, Ivan M supertra...@gmail.com wrote: Hello all, I'm facing my first GWT development. I had the idea of developing a project with a module which I have called x.gwtlogin. The server of this module can perform queries on a LDAP server. My idea is to have an instance of this module running in the application server and use its server from any other GWT application I develop. Let's say one of these applications is x.dt. I have copied all x.gwtlogin.client classes that implement the server's interfance in this application, so now I have two client packages in the project: x.dt.client x.gwtlogin.client The problem is that when debugging in hosted mode wherever I try to use a x.gwtlogin.client.Class in a x.dt.client.Class, I get the following error: [ERROR] Line 20: No source code is available for type x.gwtlogin.client.Class; did you forget to inherit a required module? I suppose the problem is that GWT is not compiling and including the classes in x.gwtlogin.client when building x.dt.client. What can I do?. Is what I intend to do possible at all?.

Re: Android Compatibility Isses with GWT (UI based, not RPC)
On Wed, Apr 8, 2009 at 12:22 PM, Evan Ruff evan.r...@gmail.com wrote: Hey guys, Little stream of conciseness here, sorry if this is a bit long/ disjoined. I was wondering if anyone had done any work with GWT and the Android Browser. While I'm getting basic functionality to work, the general speed, responsiveness and user experience seem very sluggish and, well, sorta bad. Another issue I'm having is locating a group to go to for support, examples and help. While I'm interested in GWT with Android, it seems that Android Developers Group is really only interested in native apps. Where to go for Browser specific help? I recommend the Android lists--some members of the Android browser team monitor those lists (I don't think any of them monitor this list). Also, filing bugs on the tracker is always recommended. As for trying out cupcake, you can build an emulator running Cupcake with the instructions at http://source.android.com/download . jason Anyways, some of the particulars I've run into: What group to go to? 1. Issues Controlling the viewport: No matter what I do, I can't seem to get proper control of the viewport. Editing the meta data, overflow CSS properties, insuring that the window's objects are small, etc. I'm continually getting white space borders and stuff like that. This causes weird finger behavior, especially allowing the user to browse into the white space. 2. HTML5/Gears Wrappers: I was wondering if the Gears API has an implementation to support HTML5 storage/cache issues in case of a non- gears enabled client. If not, is there a library anywhere that supports the encapsulation for GWT? 3. MouseListeners: The OS seems to swallow up the MouseUp event in order to do detection of scroll/drag type stuff. I guess I understand why it does it for the drag type thing, but it never fires MouseUp even after the drag is done. Ehh... fair enough, I guess. 4. Focus Panel ClickListeners: When I click a focus panel, a orange circle shows up in the upper/left corner with what seems like a cursor in it?

New version of Print.it
So here you can find the last version of Print.it. It works for both
1.4 and 1.5.
You can supply a DOCTYPE do be used to render the printing frame
and you can alter the way the printing frame is generated and printed
on slow machines,
http://code.google.com/p/gwt-print-it/source/browse/trunk/src/br/com/freller/tool/client/Print.java
/**
* pre
*
* Description:
*
* Generic printing class
* Can be used to print the Window it self, DOM.Elements,
UIObjects (Widgets) and plain HTML
*
* Usage:
*
* You must insert this iframe in your host page:
* iframe id=__printingFrame style=width:0;height:
0;border:0/iframe
*
* Window:
* Print.it();
*
* Objects/HTML:
* Print.it(RootPanel.get(myId));
* Print.it(DOM.getElementById(myId));
* Print.it(Just bPrint.it()/b!);
*
* Objects/HTML using styles:
* Print.it(link rel=StyleSheet type=text/css
media=paper href=/paperStyle.css, RootPanel.get(myId));

Re: Android Compatibility Isses with GWT (UI based, not RPC)
Hey Jason, Thanks for the tips. I've posted my note on the Android Developers list so hopefully someone over there has already gone down this road. As for the emulator tip, I've found some images and will be installing them shortly. Sometimes I kind of forget what I'm working with and just assume I've only got the device! So yeah, after upgrading to the new Cupcake on the emulator... meh I'd say no improvement :-(.

Hi,
You'll have to work out a token generation scheme. If you find a nice
one, post it.
Sessions will typically timeout (the timeout is app server dependent),
but I also added session.invalidate() on login to ensure that the
previous session is invalidated (e.g. two users usin the same
browser).

Carl! Your method worked fine. It's almost fully implemented,
but the only question I have that remains is the proper way to
generate tokens. I haven't ever had to generate them before - is
there an automatic way of generating unique tokens, or is generateToken
() a function I would write myself and have to ensure that each token
generated was unique?
For now, I just hard coded a random string into the code, which worked
well enough to see that the PDF did indeed open in a new window and
display as expected.
I will also need to figure out the session settings so that they are
invalidated properly, although I think I will need to do a bit more
reading on this.
// RPC code in the class which extends RemoteServiceServlet

// generate one time token that the client can use to
retrieve the

String token = 258958395ai53;
// generate test PDF
try {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(Hello World!));
document.close();
byte[] pdf = baos.toByteArray();
HttpServletRequest request = this.getThreadLocalRequest();
HttpSession session = request.getSession();
session.setAttribute(token, pdf);
}
catch (Exception e) {
System.out.println(ReportServlet::generatePDF::Exception +
e.getMessage());
}
return token;
}
// standard servlet
public class PDFServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException {
// create output stream from byte array in session
ByteArrayOutputStream baos = new ByteArrayOutputStream();
String token = request.getParameter(token);
byte[] pdf = (byte[])
request.getSession().getAttribute(token);
baos.write(pdf);
// setting some response headers
response.setHeader(Expires, 0);
response.setHeader(Cache-Control, must-revalidate,
post-check=0,
pre-check=0);
response.setHeader(Pragma, public);
response.setContentType(application/pdf);
// content length is needed for MSIE
response.setContentLength(baos.size());
// write ByteArrayOutputStream to ServletOutputStream
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
}
}
// client side code section
ReportController.getInstance().generatePDF(report, id, new
AsyncCallback() {

The simplest safest way I can think of is basically the same as other
people have already stated in this thread.
Using a token and storing data in the session means that the pdf data
is unique to the user (as long as the session is invalidated
properly).
- Send an RPC call to generate the pdf (or at least send the
information used to generate the pdf)
- The RPC service saves the pdf (or request data) in the session:
// use the data to create the PDF
