Re: iframe change listener?

[ThomasDalla]

Hi,

Why not using the LoadHandler:

Frame f = new Frame();
f.addLoadHandler(new LoadHandler() {

@Override
public void onLoad(LoadEvent event) {
_logger.info("LoadEvent: " + event.toString() + "\n" + 
 "New URL: " + f.getUrl() + "\n" + 
 "Relative Element: " + 
event.getRelativeElement());
}

});

It doesn't catch the POST parameters, but JS doesn't neither, isn't it?

Cheers,

Thomas

Re: Performance GWT-RPC, JavaScript Overlays, RequestFactory etc.

[Elizabeth Lemon]

Thanks so much for replying!

I read that JavaScriptObjects are an opaque handle in the javadoc
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/core/client/JavaScriptObject.html

When you mentioned how server side performance is different, is it
because of the protocol used to marshall and unmarshall the data once
it arrives on the server?

You mentioned that the DOM is much more of an issue? In what sense?
And how does one go about optimizing for this?

I always believed that gwt's deserialization via gwtrpc back into the
client side was the bottleneck.  Which is why I began to consider
other options such as JavaScript Overlay Types.  But then again, I
guess forgot that I would have to manage the JSON (or turn them into
POJOs, the advantage of GWTRPC you were speaking of I assume?) on the
server as well.  I suppose the plus side to this is that there is very
little deserialization that is needed to be done on the client side.

Would I be correct in saying that, since I can't change the speed of
my client's computer, I should place the deserialization/serialization
work on the server (which I could always allocate more resources for?

I guess really I'm looking for bottlenecks or an architecture that
would give great scalability~

Requestfactory and CellBrowser Context Problem

[jmbz84]

Hello,

I'm trying to use gwt CellBrowser and RequestFactory to show some
stored data as Cells in the cellbrowser. But I can't do it because of
the context of requestfactory.


Any Ideas ?

class CustomTreeModel implements TreeViewModel {
{
...
..
...

List composerproxy = new ArrayList();

private void setComposer() {
testRequestFactory = GWT.create(TestRequestFactory.class);
testRequestFactory.initialize(new SimpleEventBus());

request.getQuery("select a from Composer a").fire(
new Receiver>() {

@Override
public void 
onSuccess(List arg0) {
//Here Is my problem, How
can I transfer the value of arg0 to composerproxy in order to use it
on my CellBrowser ()
   // Tried with a for() to
insert each ComposerProxy individually  and with a separate method
insertcomposerproxy(arg0) but didnt work
composerproxy=arg0;

}
});

}

}

public  NodeInfo getNodeInfo(T value) {

if (value == null) {

setComposer();

 // LEVEL 0.
// We passed null as the root value. Return the 
composers.
// Create a data provider that contains the list of 
composers.

//HERE IS MY PROBLEM. The composerproxy
variable is empty.

ListDataProvider dataProvider = new
ListDataProvider(
composerproxy);



// Create a cell to display a composer.
Cell cell = new 
AbstractCell() {
@Override
public void render(Context context, 
ComposerProxy value,
SafeHtmlBuilder sb) {
if (value != null) {

sb.appendEscaped(value.getName());
}
}
};
// Return a node info that pairs the data provider and 
the cell.
return new DefaultNodeInfo(dataProvider, 
cell);
}
..
.
.
.

}



PD: The getQuery() function works fine and the arg0 variable has data.

JSOs are a way of coding in Java against JavaScript objects. The JSO class is a 
shim that get totally compiled out: no overhead, no wrapping of the JS object.

> 2. Which one would you say is fastest in terms of client side
> performance?

Most probably JSOs, with JsonUtils for parsing.
Next I'd say AutoBeans, then RF, then RPC.
Note that server side performance is different: the rpc protocol is much 
simpler than RF, so it's faster.

Where did you read that?!

Yes.
Most browsers can do JSON.stringify(), for others you'd have to use 
JSONObject.toString(), which has a small overhead.

> 
> Thank you so much for your input~

Choose what works best for you (in terms of protocol), not necessarily the 
fastest. These won't be the bottleneck of your app's performance, DOM is much 
more of an issue (and of course the network and the server)

Performance GWT-RPC, JavaScript Overlays, RequestFactory etc.

[Elizabeth Lemon]

Hello everyone,
I have been looking around for a really long time now on these client-
server communication strategies and have had a difficult time choosing
the right approach for my application.  It also doesn't help that I
don't have a very strong background on server sided coding :P

In any case, I am trying to find the approach that would give the best
performance on the client-side.

I know that GWT-RPC uses it's own protocol to get you to the server
side.  It is built on top of RequestBuilder and converts your data
into a content-type of (what I read was) text/plain.  From here, it
will reconstruct your java object onto the servlet.

JavaScript Overlays says that it has no overhead.

RequestFactory is supposed to be even faster than GWT-RPC.  No
serialization is required, but apparently deserialization is.

Upon these, there is the old RequestBuilder with a JSONParser.

I want to minimize the amount of time it takes for the client to
deserialize it's data with a balance of data size.

My objects aren't too deep.  At most, an object would contain a couple
of strings, and two arraylists of 100 objects than contain a couple of
other strings.

But if I can avoid the deserialization part (where I believe most of
the response time is being consumed by) by a simple eval on a JSON or
something, that would be great.

Other notes: I have flexibility in what server I can use.  However,
eventually I would like to make web services for non-gwt platforms,
though I feel like I could reuse the same business logic and use a
different entry point to the service.
QUESTIONS:
1. What does it mean for JavaScript Overlays to have no overhead?
2. Which one would you say is fastest in terms of client side
performance?
3. What does it mean that JavaScriptObjects are Opaque?
4. Since JavaScript Overlays describe us extending JavaScriptObjects,
does that mean converting it to a JSON requires less (or even zero)
time than would GWT-RPC?

Thank you so much for your input~

Re: how to link with page in gwt without update history stack?

[Jens]

I think its only possible if you do the scrolling yourself and do not rely 
on the  tag.

You can probably do something like (untested):

anchor.addClickHandler(new ClickHandler() {
  public void onClick(ClickEvent event) {
Widget jumpTo = getWidgetYouWantToScrollTo();
jumpTo.getElement().scrollIntoView(); //Version 1

scrollPanel.setVerticalScrollPosition(jumpTo.getElement().getOffsetTop()); 
//Version 2
Window.scrollTo(0, jumpTo.getElement().getOffsetTop()); //Version 3
  }
});

Re: how to link with page in gwt without update history stack?

[dodo dard]

I don't know if we can do that, because when one click on a link, browser 
native implementation is  to update history stack. It doesn't go through 
GWT.

Re: File download and Exception handling using a servlet.

[George Georgovassilis]

Hi Albert,

The way I did this is by reading SubmitCompleteEvent.getResults(), i.e.

uploadForm.addSubmitCompleteHandler(new SubmitCompleteHandler() {
public void onSubmitComplete(SubmitCompleteEvent event) {
 if (event.getResults().contains("SizeException")
 Window.alert("Data entry over limit");
}

You would just have to make sure that the servlet which handles the upload 
generates some meaningful, machine readable output which you can parse on 
the client

GWT compatible serialization techniques

[Kolv]

Hi,

I understand that GWT (2.4) implements serialization through isSerializable 
and Serializable. I was wondering if any third party packages could be used 
that advertise faster Java serialization?

RequestFactory, ServiceLocator and Spring

[kayser]

Hi,

I followed an example in this list on how to use a spring bean via
ServiceLocator. Everything works great using mvn gwt:debug but when I
try to package everything using mvn package I get compiler errors.
Here is my code:

import javax.servlet.http.HttpServletRequest;
import org.springframework.context.ApplicationContext;
import
org.springframework.web.context.support.WebApplicationContextUtils;

import
com.google.web.bindery.requestfactory.server.RequestFactoryServlet;
import com.google.web.bindery.requestfactory.shared.ServiceLocator;


public class EndpointConnectorServiceLocator implements ServiceLocator
{

/* (non-Javadoc)
 * @see
com.google.web.bindery.requestfactory.shared.ServiceLocator#getInstance(java.lang.Class)
 */
@Override
public Object getInstance(Class clazz) {

HttpServletRequest request =
RequestFactoryServlet.getThreadLocalRequest();
ApplicationContext context =
WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());
return context.getBean("endpointConnectorService");
}

}



and the mvn message when hitting the error:

Accessing GAE UserService from GWT client through requestfactory

[Madz Lang]

Hi,

I'm following the Expenses Sample that can be found in the SDK. I'm
writing a demo in which I would authenticate the user via GAE Users
Service.
I hit some problem in which the UserService userService =
UserServiceFactory.getUserService() is always null in the Service
Locator part of the Request Factory anyway here are my sample code.

This are my server side code.

package **.server;

import com.google.appengine.api.users.User;
import com.google.appengine.api.users.UserService;
import com.google.appengine.api.users.UserServiceFactory;
import com.google.web.bindery.requestfactory.shared.ServiceLocator;

/**
 * Gives a RequestFactory system access to the Google AppEngine
UserService.
 */
public class UserServiceLocator implements ServiceLocator {
public UserServiceWrapper getInstance(Class clazz) {
final UserService userService = 
UserServiceFactory.getUserService();
return new UserServiceWrapper() {

public String createLoginURL(String destinationURL) {
String loginURL = 
userService.createLoginURL(destinationURL);
return loginURL;
}

public String createLogoutURL(String destinationURL) {
String logoutURL = 
userService.createLogoutURL(destinationURL);
return logoutURL;
}

public User getCurrentUser() {
User user = userService.getCurrentUser();
return user;
}
};
}
}


public interface UserServiceWrapper {
  public String createLoginURL(String destinationURL);

  public String createLogoutURL(String destinationURL);

  public User getCurrentUser();
}


And here is my shared folder code

package **.shared;

import com.google.web.bindery.requestfactory.shared.ProxyForName;
import com.google.web.bindery.requestfactory.shared.ValueProxy;

/**
 * Client visible proxy of Google AppEngine User class.
 */
@ProxyForName("com.google.appengine.api.users.User")
public interface GaeUserProxy extends ValueProxy {
  String getNickname();
  String getEmail();
}


import com.google.web.bindery.requestfactory.shared.RequestFactory;

public interface MercadoRequestFactory extends RequestFactory{

//  UserEntityRequest userEntityRequest();
GaeUserServiceRequest userServiceRequest();
}

And here is how I instantiate it using GIN

package **.client.ioc

@Provides
@Singleton
public RequestFactory getRequestFactory(EventBus eventBus) {
RequestFactory requestFactory = GWT.create(RequestFactory 
.class);
requestFactory.initialize(eventBus);
return requestFactory;
}

And here is how I use this in my client

package **.client.view

@Inject
RequestFactory requestFactory ;

@Override
public void setUser() {
gaeUserServiceRequest = requestFactory.userServiceRequest();
gaeUserServiceRequest.getCurrentUser().to(new
Receiver() {

@Override
public void onSuccess(GaeUserProxy response) {
if(response == null) {
signingLink.setText("Sign In");
lblUserEmailAddress.setText("Guest");
createLoginURL();
} else {
signingLink.setText("Sign Out");

lblUserEmailAddress.setText(response.getNickname());
createLogoutURL();
}
}
});

gaeUserServiceRequest.fire();
}

The problem here is the GaeUserProxy response is always null. I trace
the problem and found out that the  UserService userService =
UserServiceFactory.getUserService() in my server side
UserServiceLocator  is always null. What seems to be the problem?

I'm using the GWT 2.4 BTW.


TIA

Re: GWT add JARS

[dodo dard]

Hello Vincenz,

Yes you can put those jar into a server. Depends on what server that you 
use, for example if you using tomcat you can put it into 'common/lib' 
(depends on tomcat version).
So look at your server specification.

Loading Plus-One-Button dynamically causes Popup to jump in height

[newnoise]

Hi,

I'm trying to add a "Plus-One"-Button dynamically to some popups our webapp 
is using. I'm using the following code:


HTML google = new HTML(" annotation=\"none\" href=\"http://somecutomurl.com\";>");
>
> Document doc = Document.get();
> ScriptElement script = doc.createScriptElement();
> script.setSrc("https://apis.google.com/js/plusone.js";);
> script.setType("text/javascript");
> script.setLang("javascript");
> doc.getBody().appendChild(script);
> 
> DOM.setStyleAttribute(google.getElement(), "margin", "0 5px 0 
> 0");
> 
> bottomLine.setCellHorizontalAlignment(google, 
> HasHorizontalAlignment.ALIGN_RIGHT);
> bottomLine.setCellVerticalAlignment(google, 
> HasVerticalAlignment.ALIGN_MIDDLE);
> bottomLine.add(google);
>
 
Where bottomLine is a HorizontalPanel which is added to the Popup 
afterwards. Adding it to the popup directly doesnt help.

The code itself works, the button is added, BUT the Popup enlarges its size 
for a very short second when the button is added and gets back to normal 
size afterwards. It kind of shrugs for a very short moment, which is very 
annoying.

I tried setting a fixed height and max-height for the surrounding div. And 
I tried to use the css "clip" attribute. Both not working. Also I tried 
using "AddThis"-JS-Library to add the button, same effect.

Does anyone has any idea how I can make this work? I'm sure it can be done, 
I saw apps doing exactly the same ...

Thanks!

Re: RPC Serialization of an Interface..

[Saik0]

Hi and thanks for your reply. 

i've investigated your suggestions and must say it's more complex as i 
thought. Some Interfaces go'es through the rpc serialization, others not. 
The problem is that i have some enum's in my sources and rpc don't accept 
them. I'm currently redesign my model and let you know if it works. ^^

greetings

Re: RichTextArea height size

[Saik0]

Hi, thanks for your reply.

You are right. I can't change the area itself. I've put the RichTextArea 
into a VerticalPanel and change the width and the height oft this panel. 
Now my RichTextArea looks fine ^^

greetings

Re: Problem with Window.Location.assign(url)

[Benoit S]

We also encountered this problem with GWT 2.4. To complete previous 
messages, we also noticed that it depends on the calling context. But when 
the calling context is an event handler, all browsers don't have the same 
behavior (we have the expected behavior on all browsers but IE any version).

It sounds like the problem comes from the fact that GWT code is in an 
iframe and relative path resolution is done using the calling context 
whereas we could expect GWT to resolve it in the main window context since 
the fact that code is in a iframe is hidden to user.

Here is a GWT code snippet that shows the problem:
public class IERedirectBug
implements EntryPoint
{
@Override
public void onModuleLoad()
{
final Button redirectButton = new Button("Relative Redirection");

RootPanel.get().add(redirectButton);

redirectButton.addClickHandler(new ClickHandler()
{
@Override
public void onClick(ClickEvent event)
{
// Works with all browsers but IE
Location.assign("target.html");
}
});
}
}

To investigate the problem we did several test cases in pure Javascript.

In the first case, we use a frame that is in a subfolder and that contains 
a function (as the GWT frame contains code) that does the main page 
redirection (window.parent.location.assign()). If we call this code from 
the main window (case #1), all browsers resolve correctly relative paths. 
If this code is called from the iframe (next to the function declaration, 
case #2), all browsers resolve the relative path according to the iframe 
location and not the main page location. This shows that calling context 
impacts relative path resolution and all browsers seem to have the same 
behavior (at least Google Chrome and IE 8 & 9 on which we really tested).

Main window (test.html):





   
  main
  redirect



Iframe (folder/frame.html):





  test2
  
function redirect()
{
  window.parent.location.assign('target.html');
}
  



In case #1, we add to the button declaration in test.html the call to the 
redirect function: redirect.
 
This redirects to target.html on any browser, the expected behavior.
In case #2, we call the redirect function from the frame, just after its 
declaration:
  function redirect()
{
  window.parent.location.assign('target.html');
}
  redirect();
It redirects to folder/target.html on any browser.

These examples simply confirm that calling context impacts relative path 
resolution but don't explain why IE hasn't the same behavior as other 
browsers in our GWT case.

So we tried to reproduce in a pure Javascript example the way GWT handles 
events (through the global handler), case #3. This way enabled us to 
reproduce the problem. For modern browsers and IE9, the standard global 
event handling system is used throw $wnd.addEventListener(). For IE 8 it's 
a specific code (case #4). But whatever global event handling system is 
used, Location.replace() and Location.assign() don't have the expected 
behaviour with relative paths on IE.

In case #3, we use this code (just after redirect function declaration):
// Works on any browser but IE9
window.parent.addEventListener('click', function(e) { redirect(); }, true);

In case #4 (IE8), we use this code:
window.parent.document.body.attachEvent('onclick', function(e) { 
redirect(); });

Cases #3 and #4 show that with global handler, IE has the same behavior as 
case #2 while other browsers work as in case #1, which is the expected 
behavior.

Even if the problem can be solved by API users using GWT.getModuleBaseURL(), 
don't you think it sould be fixed in GWT itself since it doesn't respect 
the GWT "execution doesn't depend on browser" principle?
I guess it could be solved by analyzing the parameter given to the assign() 
method. If it starts neither with a protocol (http:// for instance) nor 
with a slash, we can consider it's a relative path (unless I forget cases) 
and thus prefix it with GWT.getModuleBaseUrl().

Re: File download and Exception handling using a servlet.

[Albert van Veen]

Hi Bowie,

I use the code below. The PDF_HOST_URL variable is the url to my local
servlet. downloadFrame is a GWT Frame object.

pdfService.storeFormInSession(form, new AsyncCallback() {

public void onSuccess(EfPdfData arg0) {

RootPanel.get().remove(downloadFrame);
downloadFrame.setUrl(PDF_HOST_URL);
downloadFrame.setVisible(false);
RootPanel.get().add(downloadFrame);
 downloadFrame.addLoadHandler(new LoadHandler() {

public void onLoad(LoadEvent arg0) {
waitDialog.hide();
 }
});

new ReadyStateWatch(downloadFrame, waitDialog).addReadyStateChangeHandler(
new ValueChangeHandler() {

public void onValueChange(ValueChangeEvent event) {

}
});

}

public void onFailure(Throwable exception) {
new EfDialog(exception.getMessage()).show();
waitDialog.hide();

}
});

Re: RichTextArea height size

[dodo dard]

The height of an html textarea is define by number of colonne, not the
content of the area it self.
So I think you cant not set it with 100%, try with pixel.
