Re: Problem with GWT?

There really isn't enough information here to guess what is happen - what 
else could have changed, like server version or configuration, any errors 
in your browser dev tools console?

Problem with GWT?

[Germán Díaz]

When I access the web page, it remains blank. I tried different browsers, 
even on different computers, and they all showed the same problem. I am 
using the gwt-2.8.2 SDK Until a few days ago, was it working correctly? 
The curious thing is that the website works locally, that is, it is 
normally displayed in the browser, but when the project is uploaded it is 
not displayed. 
Please I need help on what can happen. Thank you so much

Re: Had a problem trying GWT 2.11.0

[Thomas Broyer]

Just published version 2024.2.5 of the archetypes that adds a DOCTYPE 
linking to the DTD to the context.xml.

I could reproduce the jetty_overlays error in env=prod, but that really 
looks like a bug in the jetty-maven-plugin (and creating the directory 
allows the server to start, but it was still missing the overlay, so no 
*.nocache.js loaded from the HTML host page).

I also found that out eventually.
Another thing: The server module needs /target /jetty_overlays  folder for 
running env-prod.

Re: user.agent problem with GWT 2.1.0 and GXT 4.1

[Jens]

Generally Java 17 works for running GWT but source level still needs to be 
11 for GWT client/shared code as GWT only supports compiling Java 11 source 
files. Server code can be anything. If you use GWT-RPC you might need to 
add some --add-opens to your server 
JVM: https://github.com/gwtproject/gwt/pull/9791

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).

FYI. Google released a GWT update in October

 I am currently very busy this week, but can try to schedule a push to

 Please remind me if I don't post links back here by next Monday.

 Worst case scenario, I can just upload jars to github and push a gist

 I used the IDE to handle vm args, as standard maven plugins are less

 did 
 not have enough free time to get that far on it).

 I'll probably update to latest java 9 spec, since the module system has

 Please keep in mind, however, that my fork has diverged from mainline

 In particular, if you start using any of the other features I've added

 recompilations.
 It's a known issue I'm avoiding looking at, since most of the 2.X stack 
 is going to go away, and I have to migrate all my magic into 
 apt-generators 
 to run as a pre-gwtc stage.

 While I might be able to help you get something that works as a proof 
 of concept, I would urge you to hold off on using it in production, as I 
 am 
 not (yet) ready to offer fulltime support.
 A couple colleagues and I are playing with the idea of offering 
 fulltime support and maintenance of 2.X around mid-September (barring a 
 funding miracle for our current money-source).

 So, please take this caveats to heart; I can probably get you up and 
 compiling, but this should all be viewed as experimental and 
 not-production 
 ready for a while yet.

Re: Problem compiling GWT code with Java9

There have been some changes [1,2] to make it (at least partially) work 
with a Java 9 VM; you can try HEAD-SNAPSHOT 
(from https://oss.sonatype.org/content/repositories/google-snapshots/) 
until we release 2.8.2 with the changes.

Re: Problem compiling GWT code with Java9

[James Nelson]

Hi.

I am currently very busy this week, but can try to schedule a push to maven 
central this weekend (I have other people waiting on it to use various 
other tools I dabble in as well).

Please remind me if I don't post links back here by next Monday.

Worst case scenario, I can just upload jars to github and push a gist of 
the pom I used, with some instructions on how to set the system properties 
to make it work.

I used the IDE to handle vm args, as standard maven plugins are less 
amenable to hacking / debugging (though I'm sure it must be possible, I did 
not have enough free time to get that far on it).

I'll probably update to latest java 9 spec, since the module system has 
undergone another iteration since I tried these hacks.

Please keep in mind, however, that my fork has diverged from mainline for 
quite a while, and does not undergo the same rigorous testing that you 
might expect.
In particular, if you start using any of the other features I've added 
(reflection, arbitrary magic method injection), it can break incremental 
recompilations.
It's a known issue I'm avoiding looking at, since most of the 2.X stack is 
going to go away, and I have to migrate all my magic into apt-generators to 
run as a pre-gwtc stage.

While I might be able to help you get something that works as a proof of 
concept, I would urge you to hold off on using it in production, as I am 
not (yet) ready to offer fulltime support.
A couple colleagues and I are playing with the idea of offering fulltime 
support and maintenance of 2.X around mid-September (barring a funding 
miracle for our current money-source).

So, please take this caveats to heart; I can probably get you up and 
compiling, but this should all be viewed as experimental and not-production 
ready for a while yet.

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).

Did you find any solution to this. I am facing same issue

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.

Problem compiling GWT code with Java9

[Dave Bradlee]

At Labkey.com we're trying to compile all of our code, which includes GWT 
code, with Java9 (due for release in the summer)getting a head start. 
We have not been able to compile GWT code, which doesn't use any new Java 
features. We're getting the error
 [java] Compiling module org.labkey.experiment.property.Designer
 [java][ERROR] Unable to find type 'java.lang.Object'
 [java]   [ERROR] Hint: Check that your module inherits 
'com.google.gwt.core.Core' either directly or indirectly (most often by 
inheriting module 'com.google.gwt.user.User')

We've had an older version of GWT but have tried with the latest 2.8 as 
well and get the same thing. I've added -logLevel=DEBUG to get more info 
and the log says we're inheriting all of the appropriate packages, 
including com.google.gwt.core.Core and com.google.gwt.emul.Emulation, which 
of course is where java.lang.Object lives. It seems like something is going 
wrong with gwt-unitCache because the log looks like this:

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.

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

Problem with GWT 2.8

[Kevin Langille]

Hi everyone,

I have discovered a strange behavior in GWT 2.8. We were experiencing a bug 
in our code and I have boiled it down to one line in the client side code.

The following line returns false which is expected.

Math.abs(Double.NaN) < 0.0001

But applying not operator to the same line also returns false.

!(Math.abs(Double.NaN) < 0.0001)

We are able to avoid this situation with additional checks but its seems 
like a bug to me. Is anyone else able to confirm this issue? This was 
working as expected in 2.7.

Thanks,
Kevin

Problem with GWT 2.8, Ant, and Eclipse

[rjcarr]

I have a really old GWT project that I just tried to compile with gwt 2.8. 
 The compilation was fine (I use ant), but when I opened up eclipse, and 
pointed it to the new gwt libraries, I am getting compile errors like this:

org.apache.tools.ant.types.FileSet: Can only iterate over an array or 
an instance of java.lang.Iterable

Looking at the ant api for the version I have and fileset is definitely 
iterable.  Then I try removing the and library and I notice it's classes 
are still available.  It seems gwt-dev.jar is bundling ant, and apparently 
a really old version where filesets aren't iterable among other old errors.

This is really strange because I never had a problem with gwt 2.7.  Any 
suggestion on how to fix this other than reverting back to 2.7?

Problem with GWT RPC and Enhanced classes that are not.

[Will Phillips]

I have recently run into a problem with GWT RPC.  I use Hibernate and I 
send my entities over the wire using GWT-RPC.  Object graphs are 
transformed before they are sent to the client to snip unwanted references 
and replace lazy loading collections, similar to Gilead if my understanding 
is correct.  At any rate, the object graph being sent over RPC is intended 
to be a graph of POJO's, and this has seemingly worked well for several 
months until I unexpectedly received a deserialization error on the server. 
 I won't post the specifics of this error here or why it suddenly occurred; 
I have debugged it and the cause of the problem appears to be:

1.  My POJO's are also Hibernate Entities and are annotated with @Entity
2.  This annotation triggers the GWT-RPC SerializableTypeOracleBuilder to 
determine my class as "Maybe Enhanced"
3.  Being "maybe enhanced" triggers the GWT serialization framework to look 
for set() methods for setting fields and, where found, to use these in 
preference to direct field access when deserializing a graph.
4.  My classes are not enhanced (and if they were, I would not want them 
treated the way GWT RPC currently does; I find the implemented solution to 
enhanced classes makes me queasy).
5.  The implementation, as it stands, can call methods on partially 
deserialized objects.  I believe this has been a long standing issue with 
GWT-RPC which has been noted before with respect to Object.hashCode and 
Object.equals being called on partially deserialized objects while 
populating collections.  I wonder if RPC deserialization should proceed in 
two passes; one to construct all objects and silently set all fields on 
those objects and a second pass to allow collections and perhaps this 
bizarre Enhanced mechanism to call methods on these objects to finalize the 
graph.  However, this question is not the nature of my post.

My issue with this is that I am unable to find a satisfactory way to 
disable this "enhanced" class detection and subsequent serialization 
behaviour that it triggers.  What I want is field based serialization and 
deserialization.  My options for disabling this "feature" seem to be:
1.  Remove the @Entity annotation from by entity beans and declare them as 
entities in xml.  Not appealing to me; I like the simplicity and 
cleanliness of using annotations.
2.  Modify the set() methods on my Entity beans so that they avoid 
generating exceptions by accessing fields which may not have been 
deserialized yet.  This is one workaround, but it's not appealing either: I 
really don't want methods being called on my objects until they are fully 
deserialized, and I don't want to litter my code with checks which 
otherwise would not be there.  I already have a specific HashMap 
implementation I use for GWT serialization which avoids calling hashCode() 
or equals() during deserialization, but at least this is self-contained.
3.  Hammer the GWT ServiceInterfaceProxyGenerator to stop it declaring my 
classes enhanced.  I did this with some success - I use a custom SIPG which 
inherits from the GWT standard SIPG, and I forcibly unset the enhanced 
setting on all JClassType instances in an overridden generateTypeHandlers() 
method.  This works well - at least the .gwt.rpc files do not have 
@ClientFields entries in them, and RPC works fine.  However it is obviously 
horrible and not a permanent solution, but it is better to me than the 
alternatives.  Unfortunately, and more critically, it does not seem to work 
in SuperDev mode, which I use extensively.  Does anyone have any 
suggestions why this might be or how I can fix it?  Happy to post in detail 
about the errors experienced here if someone feels they might be able to 
shed light on it.

What I would really like is a way of turning off this enhanced class 
detection feature which works throughout the GWT toolchain...

Any help most gratefully received

- Will

Problem with GWT 2.5.1 + FF 40

[André]

Hello GWT users!

We still use GWT 2.5.1 and can't update it quickly.

Firefox v41 was released last week and came with this seemingly minor 
modification 

 
that makes our app unusable. Looks like this isn't compatible with GWT's 
history implementation 

.

Am I on the right track in that this is the root of our problem? Is it 
possible to override the settings in History.gwt.xml 

 in 
our own App.gwt.xml (preferrably in a way that it works across all FF 
versions)?

Thanks a lot in advance!

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:

HTTP Referer problem with GWT

[JoyaleXandre]

Hello guys,

I'm using the HTTP Referer header in my login page to redirect the user to 
the page he was after a successful login. I use document.referrer in the 
HTML/Javascript stand alone page.
The problem is that with the newest version of Firefox and Chrome the 
referrer includes the GWT cache in the URL of my webapps. 

Example:
I got 
https://www.example.com/com.xxx.portal.x/F7973D44FB82877B968930220546FF58.cache.html
instead of 
https://www.example.com

Do you know what I can do to get the right address instead of the one 
pointing to the cache?
Sure I can do an ugly patch in my login page to parse the string from 
referer, but I would like to have a clean method.

Thanks

Alexandre

Maybe use the xsiframe linker which produces *.cache.js files instead of 
html files. The xsiframe linker will be the default in GWT 2.7 anyways.

How can I use the xsiframe linker?
What impact will this have on my webapp? If I still use the devMode will it 
break it?

The only difference is that permutations are now js files and not html 
files. So if you don't do anything special with the GWT compiler output 
(e.g. matching *.cache.html in a web server or similar) then you should not 
have any problems.

Compiling problem with GWT Compiler

[Minjin19]

Hi everyone, 

Im having big issues with the compilation of my project, there is already a 
GWT Web application running.  
As a side-project I now want to make a mobile application of my already 
existing GWT Web application. 
I already changed some widgets from GWT to mgwt and the project runs 
without a problem. The only thing I cannot do is compiling my project. 
Errors that I get when trying to compile with the GWT Compiler: 

Java heap space and Unable to read from byte cache. 

I already increased the size of the arguments and I also deleted all files 
from the folder unitcache. 

I also tried to compile my project without mgwt and it compiles without a 
problem. So it must be something wrong with mgwt or the way I implemented 
it. But I don´t think so, since I followed the Tutorials. 

What could be the problem? Can somebody please help me? 

Im using: 

GWT 2.5.1 
JRE7 32 Bit 
Windows XP on a Laptop
mgwt 1.2.1

Thanks in advance.

Problem deploying GWT+Maven+Spring War on tomcat 6

[efsiken]

Hello,

I developed a GWT+Spring+Maven application on eclipse helios and all works 
well on eclipse. I clean, compile and install the application without any 
problem. But when deploy the generated war file on tomcat 6, deployment is 
successful, but the application doesn't start.

Here is the error I get on the tomcat application manager:

 ECHEC - L'application pour le chemin de contexte /test1 n'a pas pu être 
démarrée

and here is the tomcat6-stderr.log file:

[gwt-contrib] Problem compiling GWT from source

Hi all,

I have attended GWT.create workshop by Michael Vogt (thanks for your great 
session!) and I would like to contribute to the GWT project. I have 
followed the instructions provided by Michael and by the README.txt file, 
but Eclipse complains about the following:
 

 BaseFooProxy.java:

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...

I am using Eclipse Indigo.

Thank you for your help.

P.S. I am sorry to bother you all with such newbie questions.

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

Hi,

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

[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.

Problem with GWT 2.5.1 and Kindle paperwhite user agent

[Eduardo José Cepas Quiñonero]

Hi everyone,

I am using GWT 2.5.1 and I am accesing to a .war depolyed with Tomcat 
7.0.32, using the browser of a Kindle paperwhite model No. EY21.

The problem is that GWT cannot get the user-agent of the Kindle correctly, 
I mean, I get the following values:

   - 
   
   *From my server*: getMyThreadLocalRequest().getHeader(user-agent) -- 
   Mozilla/5.0 (X11; U; Linux armv7l like Android; en-us) AppleWebKit/531.2+ 
   (KHTML, like Gecko) Version/5.0 Safari/533.2+*Kindle/3.0+* -- ok!
   - 
   
   *From the web* www.whatsmyuseragent.com -- Mozilla/5.0 (X11; U; Linux 
   armv7l like Android; en-us) AppleWebKit/531.2+ (KHTML, like Gecko) 
   Version/5.0 Safari/533.2+ *Kindle/3.0+* -- ok !
   - 
   
   *From GWT 2.5.1 library*: Window.Navigator.getUserAgent() -- 
   Mozilla/5.0 (X11; ; U; Linux armv7l; en-us) AppleWebKit/534.26+ (KHTML, 
   like Gecko) Version/5.0 Safari/534.26+ -- ?¿?¿
   
So, I think that the GWT function is not getting the correct value for the 
user agent of the Kindle paperwhite browser...

Any idea??

Thanks a lot in advance!!

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.

Problem With GWT 2.5.1 and Postgres 9.2. JDBC Driver

[tsstnet]

Hello,

I try to set up a small GWT application which should do a simple SQL query 
to Postgres SQL 9.2. Tests are based on
GWT demo GreetingService. Server side greeting service has now following 
constructor:

public GreetingServiceImpl() {
System.out.println(Konstruktor);
try {
 
Class.forName(org.postgresql.Driver);
 
} catch (ClassNotFoundException e) {
 
System.out.println(Where is your PostgreSQL JDBC Driver? 
+ Include in your library path!);
e.printStackTrace();
return;
 
}
try {
connection = 
DriverManager.getConnection(jdbc:postgresql://192.168.42.42:5432/eclipse,eclipse,
 
***);
} catch (SQLException e) {
e.printStackTrace();
System.out.println(Verbindung zur Datenbank ist 
fehlgeschlagen);
}
}

This ends up with following exception:

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

[kim young ill]

are you using app-engine ? it doesnt support everything your normal jdk
would do (e.g no network connection), that's why your db-connection fails.
try without app-engine

Problem use GWT 2.5.0 Super Dev Mode

[Dominic Warzok]

Hey I try to use Super Dev Mode in my web app. 

But I always get the message

 Can't find any GWT Modules on this page. code serverhttp://127.0.0.1:9876/



I follow these Steps to get Super Dev Mode running in eclipse: 

1. *add* add-linker name=xsiframe /
set-configuration-property name=devModeRedirectEnabled value=true /

* to my webapp.xml*


2. *build a new Java configuration* Run as Java App

3. *Start up code server* Output:

A lot of compiling packages and this:

* Source Maps Enabled*

*   Compile of permutations succeeded*

*Linking into 
C:\Users\warzok\AppData\Local\Temp\gwt-codeserver-2196663031883485286.tmp\com.SchumannGmbH.cam.web.Web_CAM\compile-1\war\web_cam;

*

*   Link succeeded*

*   Compilation succeeded -- 50,274s*

*Compile completed in 50873 ms*

*SLF4J: Failed to load class org.slf4j.impl.StaticLoggerBinder.*

*SLF4J: Defaulting to no-operation (NOP) logger implementation*

*SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further 
details.*

*
*

*The code server is ready.*

*Next, visit: http://localhost:9876/*

4. *Run normal dev mode* with these  programm arguments:


*-war ${workspace_loc:Web-CAM/war} -remoteUI 
${gwt_remote_ui_server_port}:${unique_id} -startupUrl Web_CAM.html 
-logLevel INFO -codeServerPort 4321 -port  
com.SchumannGmbH.cam.web.Web_CAM*

* *

Maybe here is the error ?! 


5. *Go to* http://localhost/myWebApp.html 

6. *Click Dev Mode On* 


If I set up a Testproject this will work but not with my bigger webapp, 

Any sugesstions 

Thanks in advance .

Did you compile your module once with the xsiframe linker and 
devModeRedirectEnabled?

Problem installing gwt developer plugin on Chrome/Windows 8

[Luigi Viggiano]

Hi everybody.

we are having a problem with a Windows 8 laptop and Chrome, which is 
refusing to install the gwt developer plugin.

Is this a known issue, and is there a workaround to the problem?

Thanks.
Luigi.

problem installing GWT on RAD8.0.4 in intranet

[Guy Passy]

I've seen several people asked about the problem I've encountered when 
attempting to install GWT plugin for Eclipse 3.6 (on IBM RAD 8.0.4).
In all of the threads that I saw, the solution given was to add the Eclipse 
Repository so that Eclipse would update the necessary files.

*I cannot do this* as I am on a company *intranet*!

Is it possible to update the Eclipse that RAD is installed with/build on?
Where can I get the necessary files for the installation?

Or is there another possible way to do this?

Any help would be greatly appreciated.

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/
.

Re: Findbugs problem by GWT Project.

You either need a full path to the class or end with .* if you wish to do 
all the class at the package level.  If you wish to include subpackages use 
.- suffix instead.

Problem with GWT Generator

[Stephan]

I've written a simple GWT Generator, but during GWT compiling I get an
error stating:

Rebind result 'generated class' could not be found.

I'm using GWT 2.4.0 inside of Eclipse 3.7 with the Google Plugin.

The generated code compiles properly, if I inject an error into the
generated code the compiler gripes and points me to the temp file
holding the generated code.  I'm curious what kind of issues result in
this message.

For what it is worth, I really like GWT but I find the error messaging
during the compile phase is beyond cryptic for bugs in generators.

Thanks,

Stephan

Check out the source code of gwt-connector, use 2.4. as dependency,
make the required changes,  and make the libraries against gwt 2.4.

Problem with gwt fileUpload in GWT 2.4

[James Drinkard]

Hello All,
I have a requirement to get a file, upload it to the server and then get 
the stream of bytes back in some server-side code.  I have to pass an 
inputStream from the file to a calculator module.  So I opted to use the 
fileUpload widget which appears to work fine on the client-side.  I see the 
post on the form.submit, so it appears that the file went to the server.  I 
then use an RPC service call to try and pull the file stream off the 
server.  I use an serviceImpl servlet (extends RemoteServiceServlet) and I 
try to pull the stream back with this line of code in the servlet:  
*inputStream = request.getInputStream();*

However, it doesn't appear that I'm getting anything back at all.  Is this 
doable and is this the correct approach?  I've done lots of RPC calls, so 
that is what I thought was the right way to do this, but now I'm not sure.  
I've never worked with the fileUpload widget before and opted to use it 
over the GWTUploader widget as a simpler, fast solution.  

Any ideas as to how to do this?

Re: captcha problem in gwt

What captcha vendor are you using? Most likely you have to generate a
personal key for your domain. If you don't do this the captcha will
work on localhost (for testing), but not on your domain.

And no - this is almost for sure not a GWT problem,


Best,


Raphael








 thanks in advance

Re: Findbugs problem by GWT Project.

[Thomas Broyer]

Do you really have no output from findbugs? What if you add 
xmlOutputtrue/xmlOutput (as suggested by the last line your 
copy/pasted)?

We do have:
  findbugsXmlOutputtrue/findbugsXmlOutput
  findbugsXmlWithMessagestrue/findbugsXmlWithMessages
  xmlOutputtrue/xmlOutput
in our config. I can't remember what each one does and whether they're 
required or even useful, but it works (and by that, I mean that our Jenkins 
job correctly shows us findbugs results)

BTW, this is not an error.

Findbugs problem by GWT Project.

[Kotuboy]

I have a maven GWT project and i am using findbugs to analyze the code.

plugin
groupIdorg.codehaus.mojo/groupId
artifactIdfindbugs-maven-plugin/artifactId
version2.3.2/version
configuration
targetJdk1.6/targetJdk
onlyAnalyzecom.mycompany./onlyAnalyze

/configuration
/plugin

But I am getting the following error and dont get any result from findbugs. 
The other plugins are working properly.

 [INFO] Fork Value is true
[java] The following classes needed for analysis were missing:
[java] com.google.gwt.core.client.GWTBridge
[java] Missing classes: 2 
[INFO] xmlOutput is false

 What is the difference of findbugs?? What do you recommend?

GWTBridge is in gwt-dev. Did you add that as a dependency? Mind you, I
don't know why FindBugs would need it given your onlyAnalyze...
