Re: Problem compiling GWT code with Java9

[James Nelson]

If you aren't using java 9 modules, the latest release will work.  It does 
this by reading the classpath from System.getProperty("java.class.path"), 
so if you are using standard tools for creating classpath, everything 
should work fine.  If you are doing anything non-standard for assigning 
classpaths, or if you are using java 9 modules (i.e. you supply a 
modulepath instead of classpath), this will very likely not work for you.

Per my previous comments, my colleagues (Colin Alworth and Justin Hickman) 
and I did start a GWT-based services company, vertispan.com.  If you want 
to chat, you can send an email to supp...@vertispan.com or come chat 
in https://gitter.im/gwtproject/gwt  We generally help anyone for free in 
the public chat room, since it helps everyone to learn about fixes, but for 
anything requiring dedicated engineering effort, we prefer to do a support 
contract.

While I cannot say what the team at Google has in store for java 9 in gwt 
2, I do have a prototype fix for java 9 modules on an old branch, so if you 
do run into trouble, feel free to post here, but you'll likely get a much 
faster response in gitter.  I have the jars pushed to a public-facing 
artifactory, and can give out coordinates if you have more exotic needs 
(and are willing to use coarse workarounds while a better solution is 
developed).  My fix resorts to reflection to access new java 9 classloader 
types, needs a bunch of ugly flags to open modules for reading by 
classloaders, and even had to unpack all of gwt-user and gwt-dev to avoid 
overloaded packages (no longer legal to have the same package in more than 
one jar in java 9).

Getting a prototype "this can work" was pretty easy, but getting it fully 
cleaned up with necessary modularization / refactoring is a potentially 
large chunk of work that could affect many files.  

So, I hope the "java.class.path" workaround works for you.  If it doesn't, 
come see us in gitter, or post back here (if you are ok waiting a few days 
for a response).

Re: Problem compiling GWT code with Java9

FYI. Google released a GWT update in October 
(http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_2) that 
supposed includes fixes to allow it to work with Java9. We'll be trying 
that soon.

There have been some changes [1,2] to make it (at least partially) work

Re: Problem compiling GWT code with Java9

[James Nelson]

Also, the reason gwt.xml files aren't loading sanely has to do with how 
resources are handled in java 9. 

You are going to have to either declare your source modules (with the 
gwt.xml) as `open` (no documentation for this, I found it trolling JCP 
forums),
or you can open your module to your gwt module (I built this with an 
unspeakable hack for exploration purposes) with --add-opens VM args.


If you dig into classloaders, you will discover that they will allow access 
to .class files from non-opened modules, but all other resources are 
effectively hidden unless explicitly opened.

Re: Problem compiling GWT code with Java9

[James Nelson]

Hi.

Per this thread:
https://plus.google.com/+JamesNelsonX/posts/gBfpBDnwV9V

I have actually dove into Java 9 support, and cleared all the roadblocks 
once (before the JCP pushback force the module system to get more last 
minute changes).

The main issue was not language support (easy upgrade from eclipse jdt), or 
a tiny change for try-with-resources (allows effectively final variable 
references, instead of only local variable declarations)...
The biggest problem was the changes to the classloading system.

Specifically, they no longer use URLClassLoader for system classloaders, 
meaning that any attempts to "rip out the classpath" will not work any 
longer.

I managed to hack together a working compile where I check if java 9 
classloaders are in use, and if so, use reflection (with requires 
--add-opens for using reflection on the classloader, plus opening the 
source module so that the gwt code can see external resources), to get 
access to those URLs.

What I did is only one way to fix; we could also add classpath declarations 
to gwt (I use an annotation system that can reference maven modules for my 
own compiles, so I could actually get classpath without looking inside 
classloader).  There might also be less terrible hacks we can use once the 
module APIs are cemented in place.



If you really want to play with this RFN, I can push a build of my gwt fork 
to maven central for you to try out.  I don't really have a snapshot repo, 
or time to respond to bugfixes atm (though I am considering opening a gwt 
support shop this fall, and will "do it right" at that time).  If you are 
comfortable doing local installs to maven just to assess possibilities (or 
if you maintain your own nexus repo), I could just send you jars directly 
(though, that is generally a bit sketchy, imho).

Let me know; I won't have time to do a release this weekend as it is my 
wife's birthday, but I can fit it in if you'd like (and the comments in the 
G+ post aren't helpful enough).

I hadn't tried until now, but have the exact same error with 9-ea+152 
(using package oracle-java9-installer from webupd8 on Ubuntu 16.10) on a 
simple hello-world project (that compiles OK with Java 8).

Trying to run GWT's own test suite with Java 9 might possibly help 
understand where the problem comes from.

Re: Problem compiling GWT code with Java9

[Jens]

I think it is more a class path / module path issue than a unitCache issue 
(you can always delete the unit cache or don't use it at all by disabling 
it on the command line). I guess GWT Compiler simply does not see 
Core.gwt.xml even though you have inherited it.

At least it is inconsistent with what the JVM would do, and appears to be 
different from what was seen in earlier versions of GWT. Can you file this

Re: Problem with GWT 2.8

[Kevin Langille]

Thanks for the reply.

Compiling with pretty shows the issue.

if (!(Math.abs(x - y) < 0.0001))

gets turned into

if (Math.abs(x - y) >= 0.0001)

So when Math.abs(x - y) results in NaN the if always results in false.

In my mind this is a mistake because it doesn't accurately represent what 
is happening in Java. Is it enough to report it here or what should I do 
now?

Compile your app for production but use -style PRETTY so you can better 
search in the final JS output. Then search the method name containing your 
failing code and compare the generated JS. If it works in SuperDevMode but 
fails at production then it might be an optimization bug in GWT. But that 
is something you can only figure out when looking at the generated JS code.

Additional information

Running superdev mode from Intellij failed to show the error, only once our

show the values of the expressions.

As a short term fix I added


  
  


to my App.gwt.xml which seems to fix our problems as it doesn't override

This has been fixed in GWT 2.7.0. We refactored the history implementation 
to not special case Firefox in this particular way. Just updating to GWT 
2.7 will fix this issue for you.

If that is not possible here is the main patch to make history work:

Hi,

I think ideally you'd build gwt with Ant and then go pick the just-built 
requestfactory-apt.jar for use in Eclipse.

 Based on what I can understand, it seems to be a problem related to the 
 Annotation Processor Factory Path configuration. As reported in the 
 instructions provided in the README.txt, I have added 
 GWT_TOOLS/lib/requestfactory/requestfactory-apt-2011-08-18.jar, since it 
 seems to be the most recent one. There was also a 
 GWT-TOOLS/lib/requestfactory/requestfactory-apt.jar. I have tried checking 
 and unchecking it, but the problem persist. I have also tried using 
 requestfactory-apt-2.5.1.jar, without any noticeable results.
 
 
 In addition, I have other compilation errors. For instance, it cannot find 
 the class 'com.google.web.bindery.requestfactory.vm.impl.TypeTokenResolver'.
 
 
 I am sure I am missing something in the instructions, but I can not see it...

[gwt-contrib] Re: Problem compiling GWT from source

[Michael Prentice]

I agree with Thomas. I believe it already defaults to picking up the one 
generated by the ANT build. I did the same thing and ignored that part of 
the instructions since it didn't work well. After that everything built 
well enough (with regards to APT stuff). Looks like another thing in the 
README.txt that needs updating.

Re: Problem with GWT+Hibernate

[Jens]

Change

source path=com.mySampleApplication.client/ 

to

source path=client/ 

Then please google for some GWT + Hibernate tutorials as your code also has 
some other flaws. First you wan to share a hibernate entity which is not 
that easy because hibernate rewrites your entity class which causes GWT to 
throw serialization exceptions and second if you use lazy loading then you 
can not close the hibernate session before GWT has serialized the entity. 
While serializing the lazy relationships will be fetched but if you have 
closed the session before you will get Hibernate exceptions. You should 
follow the OpenSessionInView Pattern to solve this.

Re: Problem With GWT 2.5.1 and Postgres 9.2. JDBC Driver

are you using app-engine ? it doesnt support everything your normal jdk

Re: Problem installign gwt in eclipse

[Rob]

Hi,

Draft post:

-

In this post, we're going to take a look at how we can work with GWT and 
Maven when using Eclipse's Integrated Development Environment (IDE).

So we'll need to:

   1. Install the Google Plugin for Eclipse
   2. Install the Maven Integration for Eclipse plugin
   3. Install the Maven Integration for WTP plugin

Prerequisites

You will need a Java 
SDKhttp://www.oracle.com/technetwork/java/javase/downloads/index.html(version 
1.7 or later), the Eclipse 
IDE for Java EE Developers http://www.eclipse.org/downloads/ (Indigo 
version 3.7.2 or later) and Maven 
http://maven.apache.org/download.html(version 3.0.4 or later).

I started with a fresh install of Eclipse and followed these 
recommendationshttp://stackoverflow.com/questions/142357/what-are-the-best-jvm-settings-for-eclipsewhen
 updating eclipse.ini.

You should also disable any unnecessary start-up actions (e.g. Windows - 
Preferences, type “startup”, select “Startup and Shutdown”, and then 
deselect the options you don’t need) and validations (e.g. Windows - 
Preferences - Validation, click “Disable All”, and then select only the 
options you need). You might also want to consider setting up a ram 
diskhttp://www.beyondlinux.com/2011/06/25/speed-up-your-eclipse-as-a-super-fast-ide/
.

And don't forget to add the Java SDK, Eclipse, your workspace and any other 
related folders to the white list in your anti-virus software.

*Note: *If you run into any issues when checking for updates or installing 
new software then you might need to disable your anti-virus 
softwarehttp://stackoverflow.com/questions/8367856/eclipse-downloading-content-jar-times-out-while-installing-plugins(e.g.
 AVG's Link Scanner, Identity Protection and Resident Shield).
1. Install the Google Plugin for Eclipse

The Google Plugin for Eclipse (GPE) makes it easy to import Maven projects 
that use GWT and App Engine. To get started, we first need to install GPE 
and then some additional plugins.

In Eclipse choose Help - Install New Software... and paste the update 
site URL *http://dl.google.com/eclipse/plugin/3.7* into the field named 
Work with: then press the Enter key.

Pressing Enter should cause Eclipse to update the list of available plugins:

[image: Google Plugin for Eclipse]

Select the Google Plugin for Eclipse 3.7 (and optionally the Google Web 
Toolkit SDK and the Google App Engine SDK) click Next and then follow the 
prompts. When the download has finished and the installation is complete 
make sure you restart Eclipse.

*Note:* As an alternative to installing from the update site, you can 
install the Google Plugin for Eclipse by downloading and installing an 
archive of the update 
sitehttps://developers.google.com/eclipse/docs/install-from-zip
.
2. Install the Maven Integration for Eclipse plugin

In Eclipse choose Help - Install New Software... and paste the update 
site URL *http://download.eclipse.org/technology/m2e/milestones/1.1* into 
the field named Work with: then press the Enter key.

Pressing Enter should cause Eclipse to update the list of available plugins:

[image: Maven Integration for Eclipse]

Select the Maven Integration for Eclipse plugin then click Next and follow 
the prompts. When the download has finished and the installation is 
complete make sure you restart Eclipse.

*Note:* If like me you run more than one version of Maven (e.g. Maven 2 and 
Maven 3) then you need to check your environment and make sure you aren't 
referencing more than one 
installationhttp://askubuntu.com/questions/41017/maven-exits-after-trying-to-run-it
.
3. Install the Maven Integration for WTP plugin

In Eclipse choose Help - Install New Software... and paste the update 
site URL *http://download.jboss.org/jbosstools/updates/m2eclipse-wtp* into 
the field named Work with: then press the Enter key.

Pressing Enter should cause Eclipse to update the list of available plugins:

[image: Maven Integration for WTP]

Select the Maven Integration for WTP (Web Tools Platform) plugin then click 
Next and follow the prompts. When the download has finished and the 
installation is complete make sure you restart Eclipse.
What's Next

If you have successfully installed the Google Plugin for Eclipse (GPE) and 
the additional plugins then you're ready to generate a skeleton GWT Maven 
projecthttp://kiahu.com/tutorial/generate-a-skeleton-project-using-gwt-and-maven/
.

Okay, after doing more searching I found you can't do RPC with this widget,

Hi James,

You can also use Apache commons fileupload library, it's easy to use and to

Re: Problem with GWT Service results

[Jambi]

The proble is, that the code out of your onSuccess method is called
before the request is finished.


...
RootPanel.get(mainContainer).add(new Label(Array lista 2:
+lista.toString()));
RootPanel.get().add(new Label(String.valueOf(Array
lista 2:
+lista.size(;
for(int i = 0; i  lista.size(); i++){
RootPanel.get().add(new Label(BOTON +i));
}
...

won´t work correct because your async request isn´t finished in the
time when you execute the code outside of the RPC. RPC calls are
asynchronous. That means, that the rest of the code executes directly
after the request is started. The onSuccess method gets called when
the result returns from the server.

you could put this code in an external method and call this method
inside of the onSuccess body.

Cheers, Michael

   }

esto esta fuera del contexto de asíncrono

 public void onSuccess(ArrayListString result) {
 }

ese contrato del AsyncCallback es el que se ejecuta cuando el servidor
regresa el resultado
si ahi tu result esta vacio entonces checa el lado del servidor.
no debes tener problema con lista.addAll(result);  // no addAll(0,x)
ya que esa lista se va a sobreescribir cada llamada al servidor

Re: Problem with GWT-RPC

[Noor]

Hi, check whether the server implementation is properly implementing
the service interface and check whether the arguments set in the
service interface methods is inline with the serviceasync.

Double checked the jars.
Double checked the interface + async parts.
Did a full clean+build.

Re: Problem with GWT-RPC

Caught it!

The build file that I had created was refering to the older version of
GWT SDK (and hence the older gwt-servlet.jar during compilation).

Thanks for your inputs!

 Hi everybody,

 I'm currently facing a blocking problem when using GWT google map api
 (version 1.1.0) with IE 6.
 GWT version used is 2.0.3.

 Here is the context : I have a web interface that displays 2 maps : one on
 the left that shows
 a general view and one the right that shows details of a selected zone of
 the left map.

 The left map displays squares (let's denote them A-square) that are
 clickable. When you click
 on a A-square, the second map (on the right) zooms to show details of this
 A-square. This
 A-square is composed of smaller squares (let's denote the B-square).

 There are around around 180 B-squares per map. They are also clickable. When
 you click on a
 B-square, its color changes according to the context. It is also added to a
 list of selected
 squares (or removed if the click is for unselecting it).

 I got it working but it is very very slow. It is completely unusable in
 fact. If I
 click on the button for selecting all B-squares, I can see each one changing
 of color (takes around
 15 seconds to get all of them  colored).

 I've investigated to understand what is going on. First CPU usage is raising
 to 50% while applying color.
 It seems that the A-square and B-square (and in fact all polygons) are
 displayed using SVG polygons.
 I have seen this with Firebug when selecting a B-Square. But IE does not
 have native support for SVG and
 I think the problem is that : no native support for SVG.

 I have tried to install Abode SVG plugin but it didn't change anything. I
 then tried the library
  http://code.google.com/p/sgweb/but it didn't work neither.
 So I really don't know how to solve this.

 I have to keep IE 6 as the main browser (it is working almost fine under
 firefox).

 Anyone has already faced such thing and solved it ?

 Any hint are welcome !

 A solution would be to wrap some javascript component into GWT (since
 apparently google maps
 from javascript does not use SVG components from what I understood). But I
 would like to make
 pure GWT solution work since it is already coded.

I'm going to go ahead and steer you away from there because all the
gwt-maps library is doing is translating your GWT calls into
javascript calls to the Maps API.  If you are willing to install a
plugin, try the chrome frame plugin for IE6.

Re: Problem with GWT Google-Maps-API 1.1 and IE 6

[Boris Lenzinger]

Hi Eric,

Thank you for the link. I have just installed it and tested out.
Unfortunately, this does not really change the thing. It is a little bit
faster but still unusable.

I've installed (just to check the difference) Google Chrome under Windows
and the application runs fine. But with Chrome embedded in IE6, I don't have
the same performances at all.

Re: Problem with GWT DialogBox

[Dinis]

I've been tracking the problem. It seems the cause of the problem is
setting the dialogBox animation ON [dialogBox.setAnimationEnabled
(true);]
But still I don't know why, I'm using other dialogBox'es in the
program and they draw correctly with animation ON on every browsers.

Any ideas?

Thanks,

Re: Problem with GWT Project Configuration - Inherits Module Problem

[Prosky]

Hi Rahul, thank you for the answer. I already look the getting started
guide but don't solve my problem.
Now we try to post the .xml file of each module. Maybe there is a
persone that help me.

The .xml file of module Portal that implements the entry point is
that:

module rename-to='portal'
inherits name='com.google.gwt.user.User' /
inherits name='com.google.gwt.user.theme.standard.Standard' /

inherits name=org.unicam.gwt.graphics.CanvasGraphics/

entry-point class='org.unicam.resourceome.web.portal.client.Portal' /

/module


The .xml file of module CanvasGraphics without entry point is that:

module rename-to='canvasgraphics'

inherits name='com.google.gwt.user.User' /
inherits name=com.google.gwt.xml.XML /

replace-with

class=org.unicam.gwt.graphics.client.canvas.impl.GWTCanvasImplDefault
when-type-is

class=org.unicam.gwt.graphics.client.canvas.impl.GWTCanvasImpl /
/replace-with

replace-with

class=org.unicam.gwt.graphics.client.canvas.impl.GradientFactoryImplDefault
when-type-is
class=org.unicam.gwt.graphics.client.canvas.GradientFactory /
/replace-with
/module

Can someone help me or suggest the solution?

If i must give more information about the application is not the
problem. Thank tou another time for the answer, sorry for this bad
english.

Your interface may be serializable, but are all your fields also
serializable in your implementations of this class? (ie. are all
members of AItem extends MyItem serializable?)

Re: Problem with GWT tutorial - Making Remote Procedure Calls

[John]

Guys,

Sorry for the thread, i found my mistake.

When creating the StockPriceServiceImpl instead of ticking the
'Inherited abstract methods' i ticked 'abstract', so the servlet
class was created as abstract, thus the container couldn't instantiate
it. Removing the declaration fixed the problem.

Cheers,
John

I'll post a new version so it will work on 1.5 too.

It's working fine now with the DOM.toString() method you have

 Greetings folks,

 I have an application developed in GWT and I would like to print tall
 GWT widgets (i.e. taller than one page).
 I found a method that works with Safari and Chrome browsers but it
 didn't work with FireFox.
 Maybe, it's related to the fact that Safari and Chrome are based on
 the Webkit html rendering technology while Firefox is based on Gecko.

 Anyway, I have tried to find a new approach.

 So, I have just tested the Print class from Andre Freller (the latest
 version) in order to print GWT widgets.

 http://groups.google.com.my/group/Google-Web-Toolkit/browse_thread/th...

 I don't know why but in all my tests trying to print any widget (even
 a short one) result in printing a frustratng (toString()) type of
 message like [object HTMLDivElement] or [object]

 Many people seems to succeed using this code, so I'm wondering what I
 could missed...

 So, I'm posting on the GWT Google Group, maybe someone else has
 encountered the same problem and found a solution.

 I've done my test using Windows XP,  GWT 1.5.3 and FireFox 3.0.8,
 Chrome, IE 7 and Safari 3

 So below, you will find the code have wrote to benchmark along with
 the printing class

Re: Problem with GWT Widget Printing

[HommeDeJava]

Hi Jay,

Using DOM.toString(obj.getElement()) I get something more usable.
no more  [object HTMLDivElement] or [object]

There's still some problems but I'm out of the dark age!

Thank you so much!

  Greetings folks,

  I have an application developed in GWT and I would like to print tall
  GWT widgets (i.e. taller than one page).
  I found a method that works with Safari and Chrome browsers but it
  didn't work with FireFox.
  Maybe, it's related to the fact that Safari and Chrome are based on
  the Webkit html rendering technology while Firefox is based on Gecko.

  Anyway, I have tried to find a new approach.

  So, I have just tested the Print class from Andre Freller (the latest
  version) in order to print GWT widgets.

 http://groups.google.com.my/group/Google-Web-Toolkit/browse_thread/th...

  I don't know why but in all my tests trying to print any widget (even
  a short one) result in printing a frustratng (toString()) type of
  message like [object HTMLDivElement] or [object]

  Many people seems to succeed using this code, so I'm wondering what I
  could missed...

  So, I'm posting on the GWT Google Group, maybe someone else has
  encountered the same problem and found a solution.

  I've done my test using Windows XP,  GWT 1.5.3 and FireFox 3.0.8,
  Chrome, IE 7 and Safari 3

  So below, you will find the code have wrote to benchmark along with
  the printing class

Re: Problem building GWT with JPA annotations using Ant

Hi,

You have got a Java compiler error, so I think you should include
hibernate-annotations.jar in ant comipler classpath (hibernate4gwt
just provide annotation emulation for GWT).

Re: Problem with GWT RPC call with List of DTO objects

[gregor]

It's odd that the RPC documentation still talks about typeArgs. I've
just double checked, and I have systematically removed all typeArg
statements relating to RPC parameters/return values from the last
project I upgraded to 1.5.3. All now replaced with 1.5. syntax and it
works fine.

My assumption is that specifying the type for collections in 1.5
syntax (i.e. ListMyType) means the GWT compiler uses that info in
the same way it used to rely on typeArg tags. I sincerely hope I'm
right about that..but those docs have got me worried.

Re: Problem in GWT 1.5

[Arthur Kalmenson]

Setting things like margins and padding is done with CSS. It's also
possible to do inside Javascript, but the notation is different and
you're better off using CSS.

Re: Problem with GWT 1.5 and IE 7

[Sumit Chandel]

Hello Javier,

I'm not sure I completely understand the issue you were facing. Could you
post up some sample code that would help reproduce the problem on our end?

From what I understand, you're trying to capture click events on a given
image widget. If this is the case, you should be able to add a ClickListener
implementation to the image widget that could then perform whatever action
you like onClick(). Is there any reason you couldn't use the ClickListener
instead of the MouseListener interface?

Hope that helps,
-Sumit Chandel

On Mon, Nov 17, 2008 at 11:53 PM, jamer [EMAIL PROTECTED] wrote:


 Hello
 I write because I found that if you use a image as a button in GWT,
 and we associate a MouseListener, if you use the function onMouseDown,
 like a click, in IE 7, the application will not be able to click on
 any button browser, or use the scroll bar of it (not the browser
 application) or anything. To prevent this you must use the onMouseUp

Re: Problem with gwt-maps-1.0.0RC1 and InfoWindow

 Eric,

 Thanks for the response

 0) I have tried both using marker and event.getSender with the same
 result

 1) I have checked out the specified branch, svn/releases/maps/1.0. Is
 there a guide on building the jar?


See the Making Google APIs for GWT Better in the documentation:

http://code.google.com/docreader/#p=gwt-google-apiss=gwt-google-apist=GettingStartedSource



 2) I have changed to 2.118 and now i get the map type and zoom
 controls showing. Simple using 2.X would not show the controls.


This is a common problem with the 2.x release this week:

 http://code.google.com/p/gmaps-api-issues/issues/detail?id=795

Could add a comment and click the star since your scenario isn't about using
scriptaculous?   Just mention you are using GWT and the gwt-maps API.  I've
talked to the maps  team personally, but there is nothing like real end
users to light a fire...

Re: Problem with gwt-maps-1.0.0RC1 and InfoWindow

[Eric Ayers]

0) Try replacing event.getSender() with 'marker'.  Its already marked final
(or did you try that already?)

1) The 1.0.0 RC1 release was plagued with a few issues related to
InfoWindows and  overlays returned in the marker click handler.  All the
fixes are now committed to the svn/releases/maps/1.0 branch in the source
code repository
2) There are some issues with setting the maps version to 2.x I've
encountered recently.  You might try setting your Maps API version (the
v=2.x part of the url used to load the Maps API in your module XML file)
down to a specific version, like v=2.118
