Re: PDF version of the GWT Developer Guide -- any time soon?

[MN]

interesting idea, but i would point this issue to the google code or
to the google docs team, because gwt is only using this system.

Re: How i found the real name of a obfuscated function? How i find the code lines?

[MN]

i know this, but this is not possible.

i have a running system with obfuscated code and get sometimes error
messages from user. now i need to assign this to the real code.

unobfuscated (detailed) code to place on the production system is not
the solution.

is there any other solution?

Compiling source files form external project?

[Mike]

Dear all,

I'm writing a GWT app which has three tiers: a client, an RPC server
(using the GWT RPC mechanism) and a further back-end server (RMI) used
by the GWT service.

Some classes, containing data,  are used by all three tiers. Hence
they are placed in package com.myapp.common . Since these classes do
not really belong to a distinct tier, i placed them in a separate
project. But since they ARE needed by the client, i DO want the GWT
compiler to translate them.

My problem: how can i tell GWT (1.5.3) to translate these classes?
(Without moving them into the client project because that would just
be ugly.)

Is there a way to have the  tag in the .gwt.xml file refer to
a package stored in an external project?

Thanks, Mike

BTW: in an earlier project, using GWT 1.4 instead of 1.5 i did the
same thing and that compiled without problems.

GWT 2.0 will have a "story of your compile" compiler option that,
AFAIK, will tell you those kind of things. In the mean time, I'm
afraid there's no easy solution (hmm, running in GWTShell -noserver
and try to reproduce the error, maybe?)

i just googled around this SOYC feature in the trunc, but in a sample
output of soyc-vis i dont see this mappings:

http://code.google.com/p/google-web-toolkit/source/browse/changes/kprobst/soyc-vis/?r=4195

maybe there is more of information in the xml file (in sampleInput-
folder):

in the last part with js / storyref... but i miss there also the line
numbers of the function.


have someone used the soyc? is there a small howto how i can use it?

Excluding imports on client side

[Ice13ill]

Is there a way to exclude imports when compiling a gwt application ?
Let's say i want to use a class on client and server side with two
methods: one uses gwt widgets (this is the method i want to use on the
client side) and one uses Sockets (or smth like that... code needed on
the server side).
Obviously i get an error when importing java.net.Socket.

Help with DecoratedStackPanel

[Harry]

Hi,

I need to piece of code with DecoratedStackPanel class instance. I
wanted it to be used for stack panels and few widgets will be under
that. For example: Name, Address are two Stack Panels,

Name
Text boxes with First name
Text Boxes with last name

Address
Text boxes for Address 1
Text Boxes for Address 2, City, State, Pin .

Should each Stack Panel have a 'public Widget onInitialize()' function
cant we do with  'public void onModuleLoad()' function.

Please Help, iam new to GWT.

Thanks in advance.

Harry.

gwt-rpc + webservices hang glassfish 2.1

[PeSc|O]

Hi all,

I'm getting some strange hangs with glassfish and gwt rpc services.
I'll describe my problem:

my dev tools are: netbeans 6.5 with latest updates, glassfish 2.1,
gwt-1.5.3, linux ubuntu 8.04.

situation:
on the entry point create a SimplePanel with a button. Associate to
this button a listener with the following code to be executed:

for (int i = 0; i < 10; i++) {
_query_service.doQuery(query, new AsyncCallback()
{

public void onFailure(Throwable caught)
{
}

public void onSuccess(Object result)
{
Window.alert("wh0a");
}
});
}


The doQuery () is a GWT-RPC service.
The service implementation is something like this:

public class QueryServiceImpl extends RemoteServiceServlet implements
QueryService
{
@WebServiceRef(wsdlLocation = "WEB-INF/wsdl/client/StoreService/
localhost_8139/Store/StoreService.wsdl")
private StoreService service;

public synchronized doQuery (MyObject query) {

try
{ // Call Web Service Operation
   com.my.company.Store port = service.getStorePort();
   // TODO initialize WS operation arguments here
   java.lang.String programName = "par1";
  java.lang.String programVersion = "par2";
 // TODO process result here
 java.lang.String result = port.getCfgText(programName,
programVersion);
 out.println("Result = "+result);
}
catch (Exception ex)
{
// TODO handle custom exceptions here
}

}
}


as you see the webservice is called with the automatic 'call
webservice operation...' by Netbeans.
The webservice in hosted in the local server, the same in which the
gwt-rpc service is deployed.
But in the above configuration I've a *global* freeze of glassfish. I
must restart it to have it responding again. No exception is thrown
nor result received.
The method is thread-safe, using synchronized keyword.
The hang does not happen if the webservice is hosted on another
server.
The hang does not happen if I call once the doQuery (), and then I the
for loop.


Am I missing or doing something wrong?

Re: Help with DecoratedStackPanel

[Sean]

Here, check this out. It has source code to get you started as well:

http://gwt.google.com/samples/Showcase/Showcase.html#CwStackPanel

You will only need one stack Panel, but have a StackPanel.add() for
Name and for Address.

For something like Name and Address, StackPanel seems like an odd
choice. You may want to look at the rest of the GWT Showcase and see
if something better fits what you are looking for.

Re: Compiling source files form external project?

[Mike]

I `solved' my problem by creating a separate module for the common
source files, packaging them in a JAR, and including them in the
client project by using . Not really satisfied though,
because each time i change the common package i must re-export and
import the JAR.

No, you'll have to refactor to separate the server-side functionality.

Simply put: no.

Several options:
 a) refactor your code so that client and server code are in distinct
classes
 b) include a  in your module with a dummy
java.net.Socket class so that the GWTCompiler doesn't choke (but it
won't use it in the final code as the "server only" method won't be
called by client code).

Obviously, option "a" is strongly preferred, as it also makes it
obvious that "methodB" isn't to be called by client code and vice
versa.

I haven't used SOYC, but it should give you the "origin source
location":
http://code.google.com/p/google-web-toolkit/source/browse/trunk/dev/core/src/com/google/gwt/core/ext/soyc/impl/StoryRecorderImpl.java#324
in storiesN.xml.gz (where N is the permutation index)
Information is then processed by soyc-vis to give you an HTML report

It actually is, as it has been deleted ;-)

Search for "http://google-web-toolkit.googlecode.com/svn-history/r4195/changes/kprobst/soyc-vis/sampleInput/report0-hello.xml

I don't know how to process this info though (but as soyc-vis will do
it for you, no need to worry that much ;-)

Re: PDF version of the GWT Developer Guide -- any time soon?

[Brian]

Yeah it is too bad it's not accessible offline.  Just noticed it also
doesn't work to view the pages to cache the app, going offline, and re-
viewing -- guess it's trying to pull data off the server.  Think
you're stuck until an offline version of some sort is provided...

Re: gwt-rpc + webservices hang glassfish 2.1

[tetsuo]

as i catch i right, the rpc-call is a different way to communicate,
then webservice

webservice is between 2 tiers, the rpc is a remote controller for the
client to the server. if u want to distribute your remote call to a
second app.server, u can use a webservice. for the simple remote call
from the gui (e.g. browser) use the rpc with the @remote call

Re: como agregar imagen bmp en backround

Pacholi,

En tu página principal, simplemente usa un estilo CSS en el Panel que
uses ahí que tenga una imagen de fondo, luego cambias en las demás
páginas, si cambias el Panel, entonces se irá, si no, entonces
simplemente cambias el estilo CSS por uno que no tenga esa imagen
(usando .setStyleName("tu-estilo")) en el Panel o widget al que le
quieras cambiar el estilo (imagen).

JNSI -> IFrame -> Function Issue

[Evan Ruff]

Hey guys,

I'm trying to create a simple little foray in to JSNI to do some DOM
manipulation and I'm really striking out bigtime. Basically, my
document loads an IFrame that contains and external page in it. On the
page is a JS function called "giveFocus()". I can't seem to get ahold
of the frame properly to call the function.

Has anyone got this to work sucessfully? Basically, I've got something
like this:

entryPoint
{
Frame myFrame = new Frame( *externalPage* );
myFrame.setSize( 100, 200 );
RootPanel.add( myFrame );
doFrameFunction( myFrame );
}

native void doFrameFunction( Frame frame ) /*-{
  $wnd.frames( frame ).document.callThisJSFunctionInsideTheIFrame();
}-*/;

The pseudocode is crappy but generally that's what I'm trying to pull
off.

Is this possible? Where am I going wrong?

Thanks!

Evan

well, in the example above I simplified the GWT Rpc service.
There's some more logic before the call to the webservice. Anyway,
there shouldn't be anything wrong in calling a webservice of the same
webserver (consider that I should be able to deploy the .war
everywhere without fearing that the wsdl points to the target
webserver or not).

there's something wrong in ws management.
If the RPC is called for the first time by more than a request, then
everything freezes, otherwise it works fine.

WEB-INF in hosted mode

[Tarquin]

Hi All

This is my first post, so please go easy on me!

I have checked the archives, but I couldn't find anything that seemed
to answer my questions.

I'm integrating GWT with Spring using a proxy class that derives from
RemoteServiceServlet and gets the Spring Application context as
follows:

final XmlWebApplicationContext context = new XmlWebApplicationContext
();
context.setServletContext(this.getServletContext());
context.refresh();
IssuesService issues = (IssuesService) context.getBean("IssuesImpl");

This works just fine when the project is deployed to TomCast (proper),
but when I use it in hosted mode I get:

[WARN] StandardContext[]Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method
'public abstract java.util.List
uk.co.marauder.tracker.client.rpc.IssuesService.getIssueHeaders
(boolean)' threw an unexpected exception:
org.springframework.beans.factory.BeanDefinitionStoreException:
IOException parsing XML document from ServletContext resource [/WEB-
INF/applicationContext.xml]; nested exception is
java.io.FileNotFoundException: Could not open ServletContext resource
[/WEB-INF/applicationContext.xml]

Where is the WEB-INF located when running in hosted mode?

Thanks
Paul

Re: JSNI / OpenLayers

[Gilles]

It is a little clearer now, couple of things were no correct in my
code and it took a while to get everything a little more straight.
I performed the following : click on an openLayers point to launch
java function. It works like that :

First, my native Js function largely inspired by Openlayers example
page :
---
 private static native JavaScriptObject _select(JavaScriptObject map,
JavaScriptObject layer,VectorLayer x)

/*-{

var mylayer=layer

  function select(feature)
  {

   x...@org.gt.client.map.openlayers.geometry.vectorlayer::selected
(Lcom/google/gwt/core/client/JavaScriptObject;)(feature.attributes[0])
  }


   var drawControl=new $wnd.OpenLayers.Control.SelectFeature
   (
mylayer,
{
clickout: true,
toggle: true,
multiple: true,
hover: false,
toggleKey: "ctrlKey", // ctrl key removes from
selection
multipleKey: "shiftKey", // shift key adds to
selection
box: true,
onSelect:select

}
);

map.addControl(drawControl);
drawControl.activate();

}-*/;

---
Note that :
Those three objects are passed JavaScriptObject map, JavaScriptObject
layer,VectorLayer x (VectorLayer is the self reference of the class :
this)
The path to the class in JSNI context is :
x...@org.gt.client.map.openlayers.geometry.vectorlayer
To adress a function in my class :
x...@org.gt.client.map.openlayers.geometry.vectorlayer::selected()()

How to determine if popup panel is visible or shown?

[rjcarr]

It seems as soon as I create a popup panel (PopupPanel) and call the
isVisible() method it will return true, even before I add a widget to
it and before I call show().

I can accept that it behaves differently from other widgets, but how
then do I determine whether or not popup is visible (shown)?

you bedder consider the differences between a remote control and a

the rpc is like the controller for your tv, the webservice is the like
two tv´s communicating to each other. in your example you want to
control your tv with a tv - that dosnt work.

Re: Organizing CSS with GWT

Hi Ice13ill,
I'm glad you asked! We have a recent GWT blog post by Chris Klundt and Eric
Wuebben who have given some great guidelines they've followed to build their
own application, http://studyblue.com.

You can check it out here:
http://googlewebtoolkit.blogspot.com/2008/12/gwt-no-need-to-shortchange-your-style.html

You should also be able to find a number of useful threads on the forum by
searching for terms similar to this thread title.

Hope that helps,

What happened to the incubator YouTube widget?

[Transplant]

A few months back there was a youtube widget in the GWT incubator. It
seems to have vaporized. Does anyone know what happened to it or have
pointers to the code?

You can see a screen shot of the old widget here:
http://www.gwtnow.com/2008/09/04/gwt-incubator-whats-in-it/

I'd think that a youtube widget would be extremely popular and useful,
does anyone know why it was removed from the incubator?

Re: PDF version of the GWT Developer Guide -- any time soon?

Re: Returning Nested ArrayLists from RPC

annotations. I realized that annotations were creating the warnings.
Don't use annotations.

Servlet ClassNotFoundException

[vinnybozz]

Hi, I've been following the GWT Tutorial @ 
http://code.google.com/webtoolkit/tutorials/1.5/RPC.html

Using Eclipse, I created the project with all the necessary files.
I created the 2 packages as explained:
- StockWatcher.client
- StockWatcher.server

Now when I try to run this app in hosted mode, I get the follwoing
error:
java.lang.ClassNotFoundException:
StockWatcher.server.StockPriceServiceImpl

However, looking at my xml, I have:


The souce file for this class is located at:
src\StockWatcher\server\StockPriceServiceImpl.java

And if I look directly in the folder hierarchy I find the class at:
bin\StockWatcher\server\StockPriceServiceImpl.class

My run configuration has the following Classpath:
- GWT_1.5
- src - \StockWatcher\


In all likelyhood there is a problem with the ClassPath from what I
read ... but I can't seem to find it or make it work.

Thx for the help

GWT VISUALIZATION GEOMAP MARKER ERROR

[bond]

Hi,
I've a problem using google visualization. I've tried to make in GWT
the example show here 
http://code.google.com/intl/it-IT/apis/visualization/documentation/gallery/geomap.html
(section Markers Example).

When I'm trying to draw the markers on the map, the google widget
display this error message "Google Maps API not included.".

Instead, if you display only region there are no problems and them are
show.

Any ideas?

Thanks

Re: GWT1.4 source code

[Brian]

I don't think the 1.4 source is available as a downloadable link
anymore. But you can pull the source from subversion.

svn checkout http://google-web-toolkit.googlecode.com/svn/releases/1.4
release_1.4

Or you can browse the source online:

Re: gwt-rpc + webservices hang glassfish 2.1

[PeSc|O]

http://code.google.com/webtoolkit/tutorials/1.5/RPC.html
claims
"The GWT RPC framework makes it easy for the client and server
components of your web application to exchange Java objects over HTTP.
The server-side code that gets invoked from the client is often
referred to as a service. The implementation of a GWT RPC service is
based on the well-known Java servlet architecture."

Being that that service is a servlet there's no reason why one
shouldn't use an access to a db, a call to a webservice or whatever
permitted by a servlet itself. I'm doing a browser -> (gwt) servlet ->
webservice.
I don't care about the rpc communication between the browser and the
server, the webservice can take much time to answer, and being the
call asynchronous it's all ok: when the method returns the callback on
javascript will be executed.

Re: GWT VISUALIZATION GEOMAP MARKER ERROR

[Eric Ayers]

Are you loading the Maps API?  This is the part that does that.  Add
it to your hosted HTML file.



As the page says, you'll need to replace the key ABCDEFG with your
maps API key.

Re: SerializationException when serialize a HashMap over RPC

[Vitali Lovich]

The error message tells you exactly the reason:  WeeklyAppointmentData is
not serializable.  Please refer to the serialization rules of GWT
(essentially, your classes have to extends IsSerializable, all non-static,
non-final, non-transient fields must be serializable & you must provide a
default constructor (any visibility, but it must be there).

Since you don't give the definitions for DayHourCoordenate & Appointment, I
can't give you the exact reason, but one of those classes is at fault.

Re: SerializationException when serialize a HashMap over RPC

[Alejandro D. Garin]

Hi Vitali,

The definitions for DayHourCoordenate is below in my original post and
Appointment is serializable because I make a lot of anothers RPC using
List without problems.

Re: SerializationException when serialize a HashMap over RPC

[George Holler]

The class WeeklyAppointmentData does not appear to implement IsSerializable. 
That's in the first line of the error stack trace.

Re: SerializationException when serialize a HashMap over RPC

[Vitali Lovich]

That depends on the version of GWT he's using.  As of 1.5 (or 1.4 - can't
recall the exact version), Serializable is a synonym for IsSerializable

Re: SerializationException when serialize a HashMap over RPC

[Vitali Lovich]

I think I see it.  List is not generally serializable.  The recommendation I
recall reading somewhere is to try to use super-classes as infrequently as
possible because it makes the compiler's job more difficult - also, in this
particular case, the GWT compiler is unable to determine the type to
serialize to.

Try:

private Map> mapData = new
HashMap>();

or even more preferable, change mapData to a HashMap as well.

JsArray.length giving error: HostedModeException: Expected primitive type int; actual value was undefined

[Farrukh Najmi]

I have the following code that processes a JavaScriptObject that is expected
to be a JsArray:

JavaScriptObject jso = ...
JsArray jsa = jso.cast();
int cnt = jsa.length();

I am finding that if the JsArray has a single element then jsa.length()
results in following exception.
All is well if there are 2 or more elements:

Is this a known issue or am I doing something wrong?

An example JSON fragment for the 1 element JsArray is:

"Email" : [ { "id" : 245081,
  "address" : "farr...@work.com",
  "type" : "OfficeEmail"
} ],

Thanks for any help on this issue.

Re: What happened to the incubator YouTube widget?

[Transplant]

Ok I found the YouTubeViewer in the incubator, its just not listed in
the widget documentation. It is in the incubator jar, and the API
docs, there's just aren't any other docs or demos for it. It works
well though - very cool.

IE7 clipping GWT content

[burton miller]

I have a situation where my GWT app is embedded in divs in a web page,
and I'm experiencing bizarre clipping behavior in IE7.

In IE7, when the browser is resized HORIZONTALLY smaller than the
region containing GWT widgets, then the GWT parts of the display are
clipped to the size of the window.  The regular html parts of the page
display normally.

This is apparent only when you scroll to the right.  If you resize the
window in this situation, the clipped area expands to the right in
real time.

This does not happen on other browsers, and no combination of html
doctype or quirks mode seems to help.  And I have replicated this on
several machines, so it is a consistent behavior.

This is a massive GWT app that is already in production - so any help
is welcome!

Using existing java API

[akros]

Hi!
I'm a newbie with Gwt and i've a problem: i have to import in my
application some Java API that arent emulated by Gwt. I've read on the
docs that i can add this line:   to my
project module so i've done it also importing the java classes i need
in com/JOrariGwt/jre ( the module is in com/JOrariGwt/) .
Unfortunately when i try to run the project from eclipse i have this
error:

[TRACE] Finding entry point classes
   [ERROR] Unable to find type 'com.jorarigwt.client.JOrariGwt'
  [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
[ERROR] Failure to load module 'com.jorarigwt.JOrariGwt'

the entry point is well setted cause without the classes that need the
external Java API the project run without errors.
What can i do?
thank you so much for your attention

Re: Using existing java API

[Ian Bambury]

There's nothing you can do.
GWT *emulates* Java, but only part of it. If it doesn't emulate some part of
it, you can't use it. Not on the client. You can use what you like on the
server.

question about selected item in FastTree

[newbie]

Hi,

By default, when user selects an item in the FastTree, the 'open/
close' symbol is not highlighted (only things on the right hand side
of the symbol gets highlighted instead).

I wonder if anyone know of a way to highlight the whole 'row' of the
selected item including the 'close/open' symbol.

Thank you in advance,

Lin

Invoke GWT entry point via custom JavaScript?

[markmac]

Hi All,

I am currently trying to integrate GWT into my existing application,
but Im having trouble doing that at the moment.

Currently I have heaps of custom JavaScript that I will eventually
migrate to GWT, but for now, I need to figure out how to add some
custom GWT widgets into my page, but not on page load (as heaps of
stuff is not yet loaded by the user, etc...) but rather on the
response callback from an existing AJAX call, can this be done?

Im imagining that I could call some externally exposed method that
resided within the *.nocache.js file? But Im not sure how that all
works, etc... If anyone has any resources that I could read up on or
experience in this area, that would be great!

Cheers,
Mark

RequestBuilder

[maple...@gmail.com]

How do I wait for the response is completed in another class?
For example, I have a class called GetData

public class GetData{
private String query;
private String DEFAULT_URL = "http://localhost/book.php";;
String result = new String();

public GetData(String query) {
this.query = query;
this.search();
}

private void search() {
String url = URL.encode(DEFAULT_URL + "?query=" + this.query);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);
builder.setCallback(new RequestCallback() {
public void onError(Request request, Throwable 
exception) {
}
public void onResponseReceived(Request request, 
Response response)
{
if (Response.SC_OK == response.getStatusCode()) 
{
result = response.getText();
}
}
});

try {
builder.send();
} catch (RequestException e) {
}
}

public String getResult(){
return this.result;
}
}

So, when I call

GetData test = new GetData(query);
System.out.println(test.getResult());

will return nothing. But I'm sure that it will return something.
The problem is System.out.println(test.getResult()); is executed
before the result=response.getText();
How can I fix that?

John

Re: RequestBuilder

Put the println in your async callback (or in a function called from your
async callback).

Re: RequestBuilder

[Ian Bambury]

You can't send a request to a server in one line and expect it to have
completed before you get to the second line.

This will NEVER happen because JS is single-threaded and even if the request
HAS returned, the callback will be queued to run later.

If you order something from an internet web site, it won't be there
immediately after you order it. You have to wait for it to be sent.

The 'A' in Ajax is for 'asynchronous'.

If you want to do something with the data you requested, you have to do it
in the callback, or it won't be there.

If you have a button which refreshes a table, get the button to make the
request, and pass the table to the callback. Get the callback to update the
table.

Re: RequestBuilder

[Ian Bambury]

No.
If you did that, the whole browser would lock up until the call returned.

You *could* run a timer and keep checking if the call had returned, but
there is no point since when the call has returned, the callback function
can do the work.

You need to move any logic that needs the requested data to the callback (or
have the callback make some method call on the object that needs the data).

If you don't want to do that, you shouldn't really be using Ajax. That is
what Ajax does.

If you want to be a bit more specific as to your needs, or can come up with
an example which mirrors what you are doing, you'll probably get more
specific help.

If you need to stop user input while the call is made, then the usual way is
to put up a 'loading...' message, either over the whole screen, or just in
the widget which is waiting.

Nope.  See here:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/faca1575f306ba0f/3be719c021aa19bd

One option is to define a new callback interface and pass an instance
to GetData.  That way you can define the instance in the "other file"
and still be a good browser citizen.

For example:

public interface SearchResultListener {

  void onNewSearchResult(String result);
}

public class GetData {

  public void search(String query, final SearchResultListener listener) {
String url = URL.encode(DEFAULT_URL + "?query=" + query);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);

builder.setCallback(new RequestCallback() {
  public void onError(Request request, Throwable exception) {
// handle problems here
  }

  public void onResponseReceived(Request request, Response response) {
if (Response.SC_OK == response.getStatusCode()) {
  listener.onNewSearchResult(response.getText());
}
else {
  // handle problems here
}
  }
});

try {
  builder.send();
}
catch (RequestException e) {
  // handle problems here
}
  }
}

Then, if you have an instance of GetData, you can do this:

aGetData.search("query", new SearchResultListener() {

  public void onNewSearchResult(String result) {
System.out.println(result);
  }
});

Setting background image for ListBox Item

[priya]

Hello group,

I want to set background image for ListBox Item in my GWT application.

I am using following code for this:

for (int i = 0; i < listBox.getItemCount(); i++) {
   DOM.getChild(listBox.getElement(), i).setClassName
("list_box_style");
}

CSS for this:

.list_box_stye{
background-image: url("../images/pkg_image2.bmp");
background-position: right;
background-repeat: no-repeat;
}

It is working in FireFox but not working in IE or Safari..

Is there any other way for this to work it in Safari and IE?

Priya

Any help is welcome..
