Re: mvp / gwt-presenter / uibinder
I've run some quick tests on one approach to incorporating UiBinder,
the MVP design pattern, and child view's. Most of the approaches I've
seen in the group have focused on how to add the child View to the
parent View after construction. But, another approach is to return the
child View from the parent View, and bind the View to the child
Presenter within the parent Presenter.
Here is an example. I have two presenters defined: a MainPresenter and
an AccountListViewer. First, the code for AccountListViewer:
public class AccountListViewer {
interface Display {
...
}
Display display;
public void bindDisplay( Display display ) {
this.display = display;
...
}
...
}
The MainPresenter's View/Display interface returns an object
implementing AccountListViewer.Display (similar to the HasValue type
characteristic interfaces in Ray's talk). The MainPresenter then uses
this in its constructor to bind the display to the AccountListViewer
object, as shown in the code below:
public class MainPresenter {
interface Display {
AccountListViewer.Display getAccountListView();
...
}
Display display;
public MainPresenter( AccountListViewer viewer, Display display ) {
this.display = display;
viewer.bindDisplay(display.getAccountListView());
}
...
}
Now, here is the MainView.Display implementation:
MainView.ui.xml
-
MainView.java
--
public class MainView extends Composite implements
MainPresenter.Display {
interface Binder extends UiBinder {}
private static final Binder binder = GWT.create(Binder.class);
@UiField
AccountListViewer.Display accountList;
public MainView() {
initWidget(binder.createAndBindUi(this));
}
public Display getAccountListView() {
return accountList;
}
...
}
Now we have a nice declarative layout of our Widgets according to the
parent without having to force the Display interfaces to really
understand what a Widget is. Note, you should refrain from injecting
child Presenters with a Display instance in this case to avoid
unnecessary object creation.
Some benefits to this approach is that it could allow one set of
developers/designers to work on the View/Display portion of the
application while others work on Presenter logic. Also, changing the
way the UI looks is simply a change to the associated Views and
injections. The one downside I see with this approach is the coupling
between the parent and child View's, however since there is already a
coupling of the parent and child Presenters, this doesn't seem like a
major issue.
Hope this helps some thoughts. I'm still interested to see Ray Ryan's
example once he gets some time to put it together. Hopefully it will
address some of these issues.

Java server frameworks for GWT
Hi, I began testing GWT a couple of months back and was able to build a small application using Django on the server. I really like GWT and after watching the talk by Ray Ryan at Google I/O, I am motivated to try GWT-RPC. Also, as my app gets bigger, the serialization / de-serialization process is getting to be a real chore. This is something it seems I can avoid with GWT-RPC. Problem is, I don't have any experience with using Java on servers. I want to learn but I'm having trouble deciding on a good starting point. I've been thinking about using Apache Tomcat as my test server. Are any of the other web servers better suited for GWT-RPC? Is there any Java framework that can help me with standard tasks such as authorization etc...? I've been reading about the Spring framework and the Struts framework. What are you thoughts on those? Any advice is greatly appreciated. Thanks a lot. Take care. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How to access a member ver created in the parent class
Help
I have written a class to get a spreed sheet file from the sevrer and
extract the data. This worcks, but the data is displayed in alert
boxes to see if it worcks. I called the class CGetDataBase;
I wanted to creat labels and add them to a VerticalPanel I created in
the entrypoint function. And stored it as a mener veribol in
CGetDataBase as my_ver.
I then call builder.send request and create a RequestCallBack class.
In the function handleReponse, I cannot get access to my_ver, how can
I get this to work? Ok in C++ I could use a globol, I know messey
programming. How can I do this in java
public class cGetDatabase {
private String url;
VerticalPanel my_ver;
public cGetDatabase(String address, VerticalPanel ver)
{
this.url=address;
this.my_ver=ver;
}
public boolean Send()
{
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(this.url));
builder.setTimeoutMillis(5000);
this.my_ver=null;
try {
Request request = builder.sendRequest(null, new
RequestCallback()
{
// this is in the RequestCallback class
public void onError(Request request, Throwable

Either put your HandleResponse within the cGetDatabase class (wow!
strange naming convention!) instead of the anonymous RequestCallback;
or use either "my_ver" (no "this" prefix, as "this" references the
RequestCalback) or "cGetDatabase.this.my_ver".

Re: Problems with Async Calls
need more info. Try going to the published rpc endpoints with browser and see if they're published. Check logs of the web container. Try to add logging to the client code; log events to Firebug console, for example. And check the configuration again - your webapp is configured, working fine, clean in logs, server is accessible, etc. Also, make sure that you have not hardcoded entry-point locations in the client code.

Re: Hosted mode hanging 4 out of 10times
If you look at my responses, you will see that I concentrate on the problem of the GWT app hanging, not on Java on the server side or anything else server side. I agree that non-GWT related posts (and I include all those damn EXT extensions and all that other s***) should not be encouraged, and I agree that there is a type of neo-programmer which does not embrace the Empirical Development Methodology to the extent they perhaps should. (EDM ... aka 'Trial And Error') Nevertheless, stamping on someone when they are asking a legitimate GWT question is not the way to deal with that problem. I've been on this list since August 2006, Isaac a few months later and we have seen many different 'enthusiastic' programmers realise how the list works. You have been in the group less than 2 months and three of your four posts have been about how the group should be run or telling people to stop clogging up the list, and the other one was in response to someone reading Excel data on the server FFS. Inexperienced GWT programmers don't necessarily understand what is GWT and what is real Java - it's all Java after all. Politely pointing out where the line is drawn is, in my opinion, a more reasonable approach than simply telling inexperienced programmers to go away and learn to solve their own problems. If you took your own advice, you wouldn't need to be on this list. There are different levels of experience and this list caters for them all. It doesn't exclude everyone who knows less than you do.

Re: Hosted mode hanging 4 out of 10times
If you look at the posts by Rahul, who only started posting since July, you'll find that a lot of them are off topic. For example : - how do I connect to convert is JDBC ResultSet into ArrayList - how do I execute DOS commands - how do I convert XML to PDF - how do I format XML on the server - why xml manipulations fails on server - hosted mode hangs because I did something screwy on my server and here's my sample code : <> I realize you are a helpful bunch of smart guys, but imagine if every Java beginner starts posting such questions on the GWT forum. The traffic on the GWT forum is high enough that additional noise like this really doesn't help. Having been in the business a while, I recognize a certain type of developer that post questions without making the slightest of effort in trying to read up / search for a solution on their own. Taking the liberty to fire an email to the GWT group at the first signs of encountering a problem is definitely not helpful to any party involved. Moreover responding to such questions will only encourage him to post more server related questions without putting in a concerted effort to resolve it himself. Frank "Argue"-ta.

Does GWT work in Snow Leopard?

All macs, aside from XServes, will boot in 32-bit mode under Snow Leopard. And, all macs will ship with Java v1.4-1.6 All you need to do is set Eclipse to use Java 1.5 and the problem is gone.

Re: Does GWT work in Snow Leopard?
Just to clarify: Have you tested GWT (including hosted mode) in Snow Leopard, and found it to work? Snow Leopard *does not* ship with any version of Java 5: http://developer.apple.com/mac/library/releasenotes/Java/JavaSnowLeopardRN/Introduction/Introduction.html Java for Mac OS X 10.6 "Mac OS X 10.6 contains an Apple-provided Java SE 6 version of 1.6.0_15 for both 32 and 64-bit Intel architectures."

Re: History Token
Guess a frame could be used to hide the token (so the whole site is in

A bit crude, and I also would query the point.

Re: how to determine when StackPanel index changes?
Phineas Gage,
I haven't tried it, but you could probably override either the
showStack or onBrowserEvent method. Probably showStack, something like
this:
@Override
public void showStack(int index) {
super.showStack(index);
if (index == getSelectedIndex()) {
onShowStack();
}
}
And, of course, create an onShowStack method that would only be called
when the stack is changed.
HTH,
Chad

Re: GWT - Applet communication /Urgent/
Search this forum for javascript applet communication. The code is easy but the concepts are not trivial as you must understand how GWT javascript JNI works as well as applets. GWTAI is also easy but again you must understand the use of attributes and put the java code in your gwt project. You can only pass primitives back and forth so if you are planning on doing something complicated with large amounts of data or an image then you will find this difficult. Your best bet is to get a simple example of GWTAI working and then try and get your applet working.

You wrote earlier that "... I am believing that it gets an null response"
is xmlDoc1 indeed empty?
My guess is that there is a subtle syntax error in the MDL file; which
problem IE ignores. FF on the other hand doesn't let it slide.
> XMLParser.removeWhitespace(xmlDoc1);
Does xmlDoc1 lose its contents after this call?

Re: Hosted mode hanging 4 out of 10times
ok Frank,
how do you want me to address the issue
Certainly there's is some communication gap between us.
I understood the last time you said and i was at fault and i accept
that.
My hosted mode works 6 out of 10 times
should i just give my client code? and no server code at all?

Re: Single entry point, multiple root panel Ids, display just one of them not showing
Many thanks for the explanation, and for your link. I've sent you my
details, so I'll go through your tutorials.
So how would I implement it so that I can have a single module, and
have that set up the widgets so that they can be used independently?
At the moment I have implemented it as 2 separate modules, but as we
get more and more modules this is going to get quite large, and a lot
of duplicated code for the server (rpc) calls.
Maybe your tutorials tell me this, If so then great. I'll get
there.
Many thanks.

Re: Create own widget
You'd rather use Composite then subclassing panels.
It would look like
public class MyClass extends Composit {
private VerticalPanel panel = new VerticalPanel();
public MyClass() {
initWidget(panel); // really important, this makes panel
underlying wdgt of composite
}
In this case you get 'clear' class, without all the superclass
methods.
You don't want users of your widget to manipulate it contents - it's
widget and it should be opaque. So, exposing add/remove methods is
bad.

If your using eclipse, make sure to set the encodeing to utf-8. Just go propertys on the project and set text text-file encoding to utf-8 from the dropdown.

WYSIWYG version of Google Plugin for Eclipse coming soon?
Hi, we're trying to decide whether to spend the money on GWT Designer from Instantiations. Does anyone in the community know (or can anyone from Google tell us) whether Google will be releasing a WYSIWYG designer for GWT in any upcoming releases of Google Plugin for Eclipse? Also, is there anyone out there with experience using the GWT Designer from Instantiations? Is it worth the money?

History Token
I have developed a simple web application with 4 pages that uses Hyperlinks and ValueChangeHandler to move from page to page and store history. Although I want to keep the history functionality in this application I do not want to show the token in the address bar of the browser. Also, and I am pretty sure this is connected, I would like to prevent users from entering the site from any location other than the default landing page.

Problems with Async Calls
Hello, I have a question concerning async calls on a server. We have developed a small web application with some async calls to a server and database. However the problem is that when the application is deployed on a server the calls do not work. On the local machine everything works fine and it is even possible to connect to the database, which is running at the hosting provider from the local machines The server runs apache and as the database we have chosen postgres. Is there someone who has a bit of experience with this issue? best regards --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Because he's only posted 4 times and his previous comment to Rahul was "Perhaps you should learn Java and also learn how to solve your problems instead, especially if its urgent to you - which does not make your issue urgent to anyone else. Please stop posting questions not related to GWT on this forum." The one after that was "I would request that this group require message subjects and sender names to be in English. The foreign characters in sender name / subjects are quite distracting." He doesn't seem to be entering into the spirit IMO, and if he can't take it, he shouldn't dish it out.

Re: Plugin-based application built with GWT ?
A few more things: We're actually really considering using the compiler at runtime (sic) now. Is there any chance that * GWT developers would accept and apply a patch that would alleviate the dependency that the compiler currently has on the filesystem by using a VirtualFS api (JSR 203, commons-vfs, or something simpler, tailored to the needs at hand) * the build could be update so as to produce a jar file that would facilitate these scenarios (i.e no need for Tomcat, Jetty, SWT and the javax packages when deploying in a web container) Cheers, -g On Aug 27, 1:44 pm, gjoseph wrote: > On Aug 26, 9:48 pm, gjoseph wrote: > > > > > > > Hi all, > > > I was wondering if anyone had pointers, ideas, examples, or anything > > that could help clarify if writing a GWT-based application that would > > also be based on plugins, where said plugins would consist of client- > > side code (i.e gwt modules) AND server-side components... is at all > > possible.

Yes, the name did not escape my notice. But I do find reference to it
as a surname, probably of Spanish origin. Why not give him the benefit

Please try to use a more civil tone when posting to this group.
Perhaps you could take a few minutes to read the group charter:

That might give you a better idea of the sort of community we're trying to be.

Re: Create own widget
Who could resist piling on with yet another option?
public class ButtonX2 extends Composite {
public ButtonX2 {
FlowPanel panel = new FlowPanel();
panel.add(new Button("1"));
panel.add(new Button("2"));
initWidget(panel);
}
}
Pros:
- Extending Composite gives you more control over the new widget's API
- Using a FlowPanel for layout gives you a far simpler DOM structure
(one , to be precise) and you can arrange and style the elements
within using CSS

Re: Hosted mode hanging 4 out of 10times
I hope your boss is reading your posts on this forum and your attempts
to scavenge solutions to problems specific to *your* server side
code / environment. That teeny bit of server side code you posted
speaks volumes. I know what I'd do if I saw that kind of code in my
codebase.

Re: Port to OpenBSD
I'm sorry. What are you trying to port? GWT is just a java library. Pick an IDE that runs on your system, identify the GWT libaries for your project, and you are done. There is nothing to port.

That's simply not possible (well, in IE6 and IE7, it would be, but not
on other browsers; at least with the current History implementation,
which is what 99.9% of developers using GWT actually want)

Oh, this is easy: in your onModuleLoad, instead of firing the current
history token, just do nothing with History (apart from registering
your ValueChangeHandler) or explicitly "move" to the landing page
(History.newItem("landing-page"))
Er, could you explain why you don't want the "bookmarkable" part of
the history feature? i'm having a hard time understanding your issue
with it...

Re: Create own widget
Why not just use a horizontalpanel with two buttons next to eachother?
HorizontalPanel buttongroup = new HorizontalPanel();
buttongroup.add(buttonOne);
buttongroup.add(buttonTwo);
If you want to make this into its own class, youd do;
public class myButtonGroup extends HorizontalPanel {
Button buttonOne = new Button("test 1");
Button buttonTwo = new Button("test 2");
public myButtonGroup() {
this.add(buttonOne)
this.add(buttonTwo)
}
}
Preferably in its own file.
Then you can use myButtonGroup whenever you want these two buttons.
eg.
myButtonGroup testgroup = new myButtonGroup()

Custom images for different tree leaves
I was wondering if there is a way to assign different images as icons to different leaves in a GWT Tree. All I could find was the interface TreeImages, which has methods to specify images only for Open , closed nodes and leaf. It does not provide a way to dynamically decide and assign different images to the leaf nodes.

GWT - Applet communication /Urgent/
Hi, I have implemented an Applet (for graph visualization) and want to embed it to my GWT application. I also want to achieve communication between GWT and the Applet. I have seen and have tried to use the gwtai library (http:// code.google.com/p/gwtai/) but it does not even compile under Java 1.6 (Stack Overflow error), which is a must in my project. So, is there any other way to achieve direct GWT-Applet communication or must I switch to Flash (for which the communication seems to be implemented)? By the way, I am very surprised regarding the lack of Applet support on GWT, I thought it would be trivial... :(( --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: JSON native function return value

what is actually supplied in your JSON? the first is a string, the

if you are getting the first, then your server side serializer is

JSON native function return value
hi all,
i am using GWT and JSON.
my question is regarding the native functions;
i am receiving the JSON string OK my problem starts with the return
value of the native functions,
from some reason it can only be a String,
something like:
public final native String getId() /*-{ return this.id; }-*/;
in if writing the native function like
public final native int getId() /*-{ return this.id; }-*/;
i am getting
com.google.gwt.dev.shell.HostedModeException: Something other than an
int was returned from JSNI method
'@com.fishabook.ui.client.server.JsUserDetails::getRank()': JS value
of type string, expected int
event thought that on the data base the field is defined as INT.
please advise

Re: what is going on with the gwt debugger??
sounds like the bug in JDK 1.6.0_14.

Re: Image in server side
Or even simpler way - create a servlet-imageprovider.
This means following:
1. Create a servlet which works with java2d, for example. Creates
your image in java2d, makes all necessary operations, etc. If there
are any parameters of image generation, transfer them to the servlet
as query-parameters (http://myservlet?a=110&b=123&c=aaasdfWEasdfa)
2. Set output content-type of the servlet to the appropriate image
format (resp.setContentType("image/png")
3. Flush the image body (encoded to corresponding format) to the
servlet's output stream
All you need then to get image on the client-side is to issue
something like this:
image.setUrl("http://myservlet?a=112&g=assa";);
Refer here for the details of the Image class:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/Image.html
And here for the servlet image-generator tutorial:
http://blog.codebeach.com/2008/02/creating-images-in-java-servlet.html

Re: Performance issues in GWT application
Your request needs to go through too long chain, that's why it is slow. I'm not sure what's the purpose of the proxy server. Does it do any valuable work, or anything it does is just forwarding requests back and force between internet clients and your JBoss? Also, why do you need Apache on the local machine? You could just change JBoss configuration to listen to default port eighty, thus eliminating one more item from chain. What I'd recommend is to get some domain name. 3rd level names can be optained pretty easily. And then setup DNS to point this name to your jboss static ip address. In this case clients will have direct requests, except the first time when dns request would precede loaded one.

Re: Hosted mode hanging 4 out of 10times
Hi,
This is my code:
Client side, i am calling an RPC service to connect to sqlserver2005.
Its an simple login(very basic)
greetingService.greetServer3(username,password, new
AsyncCallback()
{
@Override
public void
onFailure(Throwable caught) {
// TODO
Auto-generated method stub
}
@Override
public void
onSuccess(Integer result) {
// TODO
Auto-generated method stub
if (result == 1)
Window.alert("log on successful");
else
Window.alert("Please check the username and password");
}
My implementation on server side is
public Integer greetServer3(String str, String str1) {
// TODO Auto-generated method stub
try
{
Class.forName
("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
conn =
DriverManager.getConnection("jdbc:sqlserver://
STI1121081:1433;database=Sql-obtv", "username", "password");
stm =
((java.sql.Connection)conn).createStatement();
System.out.println("Values of string
name"+str+"value of
pass"+str1);
rs = stm.executeQuery("select * from
Password");
while (rs.next())
{
user =rs.getString("Username");
pass = rs.getString("Pass");
}
conn.close();
} catch (Exception e) {
connString = e.getMessage();
}
user =user.replaceAll("\\s+$", "");
pass = pass.replaceAll("\\s+$", "");
if (str.equals(user)&& str1.equals(pass))
return 1;
else
return 0;
}
Also I am not using the Google Application engine as i am integrating
with sqlserver2005. I have seen similar problems whenever i try
integrating with sqlserver2005. I am using jdbc4 driver.

How to use multiple servers in a single client
Hi I am working on a GWT application. In this, what my client needs is I send calls to different servers on basis of request types. Suppose there are 4 request types SELECT/INSERT/UPDATE/DELETE on basis of operation to be performed on server. If request type is SELECT, we need to send request to SERVER_1 and if request type is INSERT, UPDATE OR DELETE, we need to send request to SERVER_2. Now my question is how to send call to 2 different servers through same client window.

Re: Single entry point, multiple root panel Ids, display just one of them not showing
Because your app is giving up when it can't find slot 1.
It also gives up when it can't find slot 2, but by then it has shown the
button.
Look in the other window that pops up when you start your app and you'll see
java.lang.NullPointerException: null

HTML templating
Hi, we are evaluating GWT (actually GXT on top of it) and everything was perfect until we had to reproduce the final look and feel. What we want to achieve is for example something like this: Shopping cart 0 Items in your shopping cart Show cart with the same styles associated but it seems quite difficult since the HTML is dinamically generated. Overwriting the on Render method seems to me to complex and BTW a risk since the code working fine with one GWT version today couldn't working after an upgrade. I would love to have something like in Wicket where the HTML template s specified and than the final page is rendered based on that leading HTML. I saw different templating extensions for GWt but I'm not sure if there is one fitting our needs. Is there something out there? Which is the best approach to follow (extending the base template, etc. etc.)?

Re: mvp / gwt-presenter / uibinder
(Addendum: Thomas's answer beat me to it, but since I noticed it after
writing this post, I will post my answer anyway ;) )
I did not have a dev environment setup when I posted this, so did not
test this. I obviously should have, because I did not see the
recursion in what I was trying to do.
As you guessed it, the problem is that we want to inject the same
Display interface (MyPresenter.Display) in two different places:
- in the view, where we want Gin to use the @Provides factory method
(which creates a new view, injects it into a new presenter, and
returns the view)
- in the presenter, where we do NOT want to call the @Provides method,
but instead bind MyPresenter.Display to MyPresenterView in the
"standard" way.
Guice's private modules would have solved this problem elegantly but
they are not yet available in Gin:
http://google-guice.googlecode.com/svn/trunk/javadoc/com/google/inject/PrivateModule.html
Here is what I did instead:
I took as a basis the example project from this good gwt-presenter
tutorial:
http://blog.hivedevelopment.co.uk/2009/08/google-web-toolkit-gwt-mvp-example.html
I created a new Guice binding annotation:
@BindingAnnotation
@Target( { FIELD, PARAMETER, METHOD })
@Retention(RUNTIME)
public @interface ViewForPresenter {
}
I created a new presenter:
public class TestPresenter extends
WidgetPresenter {
public interface Display extends WidgetDisplay {
HasClickHandlers getTestButton();
}
// Notice the @ViewForPresenter annotation here
@Inject
public TestPresenter(@ViewForPresenter Display display, EventBus
eventBus) {
super(display, eventBus);
Log.info("TestPresenter created");
bind();
}
@Override
protected void onBind() {
registerHandler(display.getTestButton().addClickHandler(new
ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Window.alert("Button clicked!");
}
}));
}
@Override
protected void onUnbind() {
}
public void refreshDisplay() {
}
public void revealDisplay() {
}
public static final Place PLACE = null;
@Override
public Place getPlace() {
return PLACE;
}
@Override
protected void onPlaceRequest(final PlaceRequest request) {
}
}
And its view:
public class TestView extends VerticalPanel implements
TestPresenter.Display {
private final Button testButton;
@Inject
public TestView() {
Log.info("TestView created");
testButton = new Button("Test");
add(testButton);
}
@Override
public HasClickHandlers getTestButton() {
return testButton;
}
public Widget asWidget() {
return this;
}
@Override
public void startProcessing() {
}
@Override
public void stopProcessing() {
}
}
Updated the module:
public class GreetingClientModule extends AbstractPresenterModule {
@Override
protected void configure() {
[...]
bind(TestPresenter.class);
// First binding for TestPresenter.Display, which will be used
when we use the @ViewForPresenter annotation
bind(TestPresenter.Display.class).annotatedWith
(ViewForPresenter.class).to(TestView.class);
}
// Second binding for TestPresenter.Display, which will be used
when no annotation is present
@Provides
TestPresenter.Display provideTestView(TestPresenter testPresenter)
{
testPresenter.bind();
return testPresenter.getDisplay();
}
}
And modified the GreetingView to inject TestView and show it:
public class GreetingView extends Composite implements
GreetingPresenter.Display {
[...]
@Inject
public GreetingView(TestPresenter.Display testView) {
Log.info("GreetingView created");
final FlowPanel panel = new FlowPanel();
panel.add(testView.asWidget());
[...]
And voila:
2009-08-28 13:48:10,068 [INFO ] TestView created
2009-08-28 13:48:10,120 [INFO ] TestPresenter created
2009-08-28 13:48:10,131 [INFO ] GreetingView created
2009-08-28 13:48:10,219 [INFO ] GreetingPresenter created
Now, if you inject TestView anywhere in your application, it will
instantiate a new Presenter/View.

Etienne

Single entry point, multiple root panel Ids, display just one of them not showing
Hi,
I'm just getting to grips with GWT and have created some cool
widgets. However, I have a problem. The following illustrates this
If I have a GWT app that in the 'onModuleLoad()' of the entry point
class has the following
RootPanel.get("slot1").add(new Button ("button"));
RootPanel.get("slot2").add(new Label ("label"));
Then I have an html page with
Then the button and label show.
If I just have
Then the button shows.
However, If I just have
Then I would expect just the label to show, but it doesn't!
Any ideas why not?
My actual application is more complex, but still just adds different
widgets to the root panel. As I want to embed these widgets in an
existing servlet application I want to call the different widgets on 2
different html pages. So one page would show widget1, and another
widget2. This has the same problem as above that widget2 does not
show.
Many thanks

RPC Tomcat File class
Hi,
I want to search for files on my server and modify them.
In hosted mode all runs fine, also compile/browser runs fine. Then I
compile my program. The compilation was succeeded.
When I deploy my gwt (1.7.0) app to a tomcat 6.0.20 server the rpc
call fails, because my list of files is null. So I get a
NullPointerException.
I think the tomcat has no permission to the filesystem.
Therefore I add this to my cataline.policy file:
"grant codeBase "file:${catalina.home}/webapps/-" {
permission java.security.AllPermission;
};"
But it doesn't work.
any suggestion?
OS: Windows XP

Re: Possible to cancel an event dispatch loop?
On 28 août, 05:31, Chris wrote:

IMO you shouldn't depend on your handlers call order, you'd rather
have a single handler that eventually defers to "subhandlers" (that'd
probably wouldn't be ClickHandler's actually) to enforce the call
order and what to do on each step.

No.

As I said above, I'd rather had a single ClickHandler doing something
like:
public void onClick(ClickEvent event) {
if (validate(event.getSource())) {
doSendRpc();
}
}
> I don't see an obvious way to cancel out of the dispatch loop.
Throw an exception maybe ? ;-)

Re: Spinner Widget in 3d
Theres no inbuilt 3d rendering engine in javascript or gwt, so you'd either have to find one and try to make it work with gwt, or you'd have to code your own ver the canvas element. (which lets you draw anything 2d, and thus with smart code you can make anything 3d). Both probably very hard tasks.

Yes, typical circular dependencies...
You can simply use a named binding for where you want your StatsView
to be injected (not tested!):
// will inject a StatsView instance into StatsPresenter
bind(StatsPresenter.Display.class).to(StatsView.class);
...
@Provides @Named("er...no idea")
public StatsView providesStatsViewFromStatsPresenter(StatsPresenter
presenter) {
return presenter.getView();
}
and in your MainPresenter:
@Inject
MainView(@Named("er...no idea") StatsView statsView) {
...
But all of this also depends on how you're typically injecting your
presenter+view into other presenter+view (where the presenter has some
public methods that the "parent" presenter will call); then even if
StatsPresenter has no such method, I would inject it the same, just
for the sake of being consistent throughout the app.

Re: Heavy performance problems in ie6 and ie7 with both gwt1.6 and gwt1.7
After more research we've found out that it depends on StringBuffer. We're using a StringBuffer to store client logs in. If needed, this buffer can be dumped out to a file. When we commented out the line in our log method that uses the StringBuffer.append() method, it works much faster on ie7 as well. This is a bit strange since the StringBuffer should have been improved between gwt 1.5 and 1.6 but it seems that it is quite the opposite. Or have we missed something? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Yes. Doing it the way you suggest works fine, i've just gave it a try - thanks!. I answer inline below, but with this new structure there's one thing related to gwt-presenter. The constructor of a Presenter (a WidgetPresenter) looks like: (final Display display, EventBus eventBus, final DispatchAsync dispatch) where the Display is the interface for the View. If i'm instantiating the Presenter inside the View, then i need to define the EventBus and DispatchAsync as dependencies for the View, which are simply passed on to the Presenter along with the View instance itself. It works... but these are not really dependencies on the View. > > 2) Given my solution above, i need to make sure that the StatsView is > > a singleton, otherwise the Presenter instantiates a new StatsView > > which is different from the one created by the UiBinder. > > Er, I don't understand... This was just due to the way i was using it. The UiBinder would create a StatsView instance, and the StatsPresenter, which i would inject in another class, would get a StatsView injected itself - a different one. So making both singleton would help, but it was just a big mess. > > Again i try > > to use dependency injection by defining in the MainView a StatsView > > field as in: > > > @UiField(provided=true) > > StatsView statsView; > > If StatsView has dependencies that should be injected view GIN in its > constructor then yes, that the way to go > > > I then add in my injector: > > bind(StatsView.class).in(Singleton.class); > > See above, I don't understand why it has to be a singleton (actually, > I believe it shouldn't) > > > but either this or using a Provider method instead gives me the > > following: > > 00:01:18.766 [ERROR] Failed to create an instance of 'MainView' via > > deferred binding java.lang.NullPointerException: null at > > com.google.gwt.user.client.ui.ComplexPanel.add(ComplexPanel.java:77) > > at com.google.gwt.user.client.ui.VerticalPanel.add(VerticalPanel.java: > > 53) at > > ... > > > Any hints on this?

Re: Performance issues in GWT application
Hi David Thanks for your reply. But I am a newbie in these type of mappings & creating named servers. Could you please explain which type of professional services you are writing about. Also it would be better if you can provide some links/articles in this regard. Ganesh.

Re: gwt 1.6 eclipse plugin
Hi Philipmac You can install the Eclipse plugin following the instructions here: http://code.google.com/eclipse/docs/getting_started.html#installing and it could be helpful to import the existing project following the steps here: http://code.google.com/eclipse/docs/existingprojects.html Hope this is helpful!

Re: bmi.js interfering with GWT (mobile connection
I should add, that this not only completely stops our GWT-based appplication from loading whenever someone is connected via a mobile connection with a provider who is injecting this bmi.js-script (see below). When on such a mobile connection that uses this script, not even the GWT Showcase at http://gwt.google.com/samples/Showcase loads! (Sites based on older GWT 1.5 versions seem to load without a problem) One can load the application in the same browser and just switch connection to mobile and back to normal DSL connection and the problem appears and disappears. One workaround is to reload each page with Shift-F5, which apparently disables this compression. Or you can block the script and it works, however none of this is a general solution for the average user. For some reason when the bmi.js script is used, Firebug shows that all requests that should go to //myfile.abc just go to / myfile.abc - where (obviously) the file is not found - thus nothing is loaded at all. (GWT 1.7.0) Does anybody have any idea why this could be happening or how to fix this? Maybe this script somehow messes up the order of injected javascript?

I gave this a try, it looks nice. But couldn't make it work, here's
what i did.
In my injector module:
@Provides
StatsView getStatsView(StatsPresenter presenter) {
return (StatsView)presenter.getDisplay();
}
In my StatsPresenter constructor:
@Inject
public StatsPresenter(final Display display, EventBus eventBus,
final DispatchAsync dispatch) {
It looks ok, but the Display in the StatsPresenter is a StatsView
instance, so i additionally have in my injector module:
bind(StatsPresenter.Display.class).to(StatsView.class);
I get a StackOverflowError, which i'm thinking is due to a loop in the
DI. Instantiating a StatsPresenter will trigger the need for a
StatsPresenter.Display which is a StatsView, which then instantiates a
StatsPresenter, ... just a guess but it looks like this.
Did you give this a try yourself?
Thanks,
Ricardo

Re: Image in server side
yes, but you won't be happy with the binary data in the client side :) the way to go is: * create the image on the server side - store it in a cache (or somewhere else) * tranfer the image path/name to the client * let the client crete an image with this name/path * and then the client-browser will issue a get request to the server which will return the binary data for the image On Aug 27, 6:25 pm, osquitranki wrote: > Hi, > > Is possible make a image in the server side and send it in a JSON call > by client? > > Thanks!! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Issues Debugging GWT apps
OKAY, finally got it working by changing the JRE configuration. Followed these steps. Launched debug configuration. run -> debug configurations (Opens up the project settings) choose JRE tab click Alternate JRE Add a new JRE by passing the installed JDK directory path (make sure the new JDK is selected in the drop down list). Now debug. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT cannot display Chinese Words or JAPANESE words correctly
Hi, That is not a GWT issue but rather a HTML issue. Make sure that: a) you use a font that supports i18n b) make sure that you use a charset that supports i18n. Put something like this in your HTML-HEAD section.
