my project structure look like this:

 ...some other small non gwt-related modules


i come up with this: (in webapp-client module) but gwt:compile still
complaining :

on project webapp-client: The parameters 'moduleName' for goal
net.ltgt.gwt.maven:gwt-maven-plugin:1.0-rc-5:compile are missing or invalid


 

net.ltgt.gwt.maven
gwt-maven-plugin


m1

m2

Re: Mojo's maven-gwt-plugin or Thomas's maven-gwt-plugin?

['kim young ill' via GWT Users]

hi there, i'm considering moving  to gwt2.8 for (mostly because of jdk8)
and switching to Thomas's plugin, i have several separate gwt modules in
webapp-client-module, in the mojo plugin i can put it like this:
 


org.codehaus.mojo
gwt-maven-plugin


com.app.client.module1
com.app.client.module2
com.app.client.module3








what would be the alternative for thomas's plugin ? do i need to create
separate profiles for each module ?

thanx

Re: Using RequestFactory with php backend. Is it possible?

[kim young ill]

hmm, interesting, i dont think it's worth it,  you would need to be able to
decode/encode the json-format of RF @ your php-serverside (method call,
entity-identity payload ...), i think the Rest-way would make you move
faster, so you can keep your php part & exchange the client part for
whatever you feel comfortable with

vanilla-gwt with errai

[kim young ill]

hi there, anyone out there has any experience using vanilla gwt with errai
? there're some cool things from errai (event-bus, server-push) i want to
use, but i dont want to rewrite the existing-app to use errai, especially
gin/guice (i'm using mainly request-factory with guice/gin,
place/activities & editor). i look thru the docs of errai & it looks like
you're tied to the container injection framework of errai.

thanx

gin field injection

[kim young ill]

hi there,
i got into an issue with gin, like this:

bind(MyMessages.class)in(SingleTon.class)

interface MyMessages extends Messages{

@ImlementsBy(MyWidgetImpl.class)
interface MyWidget {
}

@Singleton
class MyWigetIml implements MyWiget{
@Inject MyMesages msg

public MyWidgetIml(){
//bindUI...
msg.txt1();
}
}

msg.txt1() always throws NPE.
bind with EagerSingleton doesnt help either.


a quick fix would be injecting MyMessages into the constructors, but if i
have a tons of widgets which use MyMessages ( and probably other resources
like Images), that'd be many repeated/boilerplate-codes.

is there a a better way to do this ?

thanx alot

Re: client-side validation with request factory

[kim young ill]

thanx, is there a list somewhere about (un)supported annotations ? i just
figured out @size(min=, max=)  doesnt seem to work either, if at the end u
have to mix to much custom-validation code with validation-api, i'd better
not using it


thanx

in the sample project of gwt-2.5, the client-pojos are annotated directly,
but what about proxies ?

 Hallo,

 After finishing development on my GWT (2.4) project, I found out, that
 the compiled version does not work exactly as in the development mode.

 Some method ( isValid() ) seems not to be called.

 Calling code (simplified):

 boolean valid=true;
 if(! mypanel.isValid())
valid=false;

 method:

 public boolean isValid()
 {
 updateSomeData();
 return true;
 }

 This works well in development mode, but in compiled code, isValid()
 was never called. From this point things got strange. I've added a
 log-command to the method:

 public boolean isValid()
 {
 updateSomeData();
 logger.info("method called");
 return true;
 }

 The method was called and the log entry written.

 I removed the log entry and changed the calling part to:

 boolean valid=true;
 boolean x=mypanel.isValid();
 if(!x)
valid=false;

 Now again the method was called. This seems to be some problem in the
 compiler optimizer. After switching off the optimizer, the compiled code
 did work as expected.

 After searching the web, I found an issue report, DESCRIBING THE EXACT
 SAME PROBLEM !

 See: http://code.google.com/p/google-web-toolkit/issues/detail?id=6551

 So this is a know issue since over a year and present since GWT 2.3 !!!

 I have not problem with bugs, but I can't understand, why no one seems
 to care. Can there be something more serious, than a compiler-bug ?

 If you search the database, there are some compiler / optimizer issues,
 that seem not to have been fixed.

 Example:

 http://code.google.com/p/google-web-toolkit/issues/detail?id=5739

 This is scary ! If you can't trust the compiler, you'll never know, if
 your code works in production as I did under development. Adding / removing
 a single line may change the whole behavior. Testing will become a
 nightmare !

 Some one should care.

 regards

 Marc

Re: RequestBuilder and Browser same-origin-policy

[kim young ill]

hmm, not sure if i understand u correctly:

"make a POST request to 3rd party originating from my own server" .

u just need to make a http request to the target host with required params
, i asume you do it from server  with jdk, so no dom/js is required, that
also means no refresh...

Re: RequestBuilder and Browser same-origin-policy

[kim young ill]

you can have a look at apache http-client or if it's simple, just the
built-in httpurlConnection of the jdk

i think the most suitable solution is using a formpanel as thomas said, so
u can stream the back the data to client right away  from your servlet

Re: GWT and HttpServletResponse

[kim young ill]

you can generate some metadata on serverside & send back to client (via
rpc) &  let client generate the path to your file & then either redirect
(with Window.assign(url) or let user click to the generated link to get the
file.
i dont think you can get binary input stream from client to get the file
directly with rpc

normally it's the container (webserver) who can handle this.

AFAICT, if u have a (html) form (which wrapped by a formpanel), this will
be posted only once to server , for which u'll get a response, this form in
this case will not be available for u anymore on the client side to do a
re-post.

or did i misunderstanding when u says "a FormPanel make
multiple POST requests " ?

Re: fileupload in gwt

[kim young ill]

anyone know how to handle a cancel-upload case ?
i guess if the client just cut the line. server will get IOException & can
handle that. what about clientside with FileUpload widget (or i guess
Formpanel should do sth here )?

fileupload in gwt

[kim young ill]

hi there
what's the best approach to handle a simple fileupload in gwt ?
normally it would be a normal POST with File-Field, problem is that a post
to a servlet will make the page "refresh", that means user will be redirect
from current page. is there a lightweight-approach which doesnt require
this ? possibly an iframe which contains the form ?

thanx

Re: Session management in GWT

[kim young ill]

no, this.getThreadLocalRequest().getSession() will create one if it doesnt
exist yet. once created, u'll get the same session. if the request has a
valid cookie which corresponds to a existed session, there'll no new
session created.

hth

but if u call it at different place , due to threading, u'll prob. get
different result. so call it once at the method which is also declared at
rpc-client-interface & passe it around for your request scope.

Re: Session management in GWT

[kim young ill]

in your securityServiceImpl.getCredentials() you should get Session via:
getThreadLocalRequest().getSession(), then pass it to

addToSession(HttpSession session, String label, Objectval)
you here u have session, why called getThreadLocalRequest().getSession()
the second time ?

Re: GWT and Generated file download

[kim young ill]

depends how long u wanna keep the files. u can store files somewhere, put
filepath in session, when session got destroyed ( put a listener in
contextlistener), read out the paths and remove them.

Re: FTP file upload in gwt

[kim young ill]

doesnt work, gwt/web uses HTTP which is not FTP
if u want FTP, its enough to use an ftp client, (Window$) Explorer will do
the job (if u use it), otherwise use Finder(mac) or Nautilus (Linux)

GWTimageresource load seperately

[kim young ill]

Hi,

i want to use ClientBundle to put all images together,

plain simple like this:


@Source("img/priv.png")
ImageResource priv();

@Source("img/logo.png")
ImageResource logo();

@Source("img/back.png")
ImageResource back();

@Source("img/print.jpg")
ImageResource printIcon();

for unknown reason, when i set Image.setRecource(bundle.priv()), the image
priv/png is loaded extra from /module/*.cache.png.
but it's not the purpose of using bundle, like this i could have use plain
markup with url-property to get the image.

did i do some thing wrong here ?

Re: Saving Object to fole on Server

[kim young ill]

i dont think i understand what you want to do here.

if you want to save an object, you have to serialize it & write it to
server.
if you want to use http, you can do it with POST (multipart), on
serverside, you need to write a servlet to handle the request: parse it &
write it to wherever you want
if its not a http-server ( just a server socket), you can send the stream
directly

look like you missunderstand the concepts of http-protocol & file-system

Re: mvn gwt:run failed

[kim young ill]

problem solved:

http://code.google.com/p/google-web-toolkit/issues/detail?id=3557

i just use the approach with JDTCompiler adapter & add this line to my
pom.xml

-Xmx1024m
-Dbuild.compiler=de.webapp.JDTCompiler16

just strange that there're not so many complaints, looks like everyone use
plain html as hostpage instead of jsp although on the gwt-devguide there's a
part where dynamic-hostpage with jsp was described as elegant

editor framework suggestion ?

[kim young ill]

Hi gwt gurus

i want to to use editorframework implement this:

Person extends ValueProxy
  -name:String
  -attributes:List

KeyValueProxy extends ValueProxy
 -key:String
 -value:String

 want to populate a popup-editor   where you can edit person :
add/remove/edit attributes, change name.

i think of 2 possibilities
1-a separate  celltable for attributes with a backed Listdataprovider, (but
then it's could be difficult to keep in sync with the driver ?)
2-use a CompositeEditor . 1 editor for each

any suggestions/example would be great

thanx

xxx.ui.xml is not in GWT client package

[kim young ill]

hi there
as long as gwt-project get a deeper/complexer package layout, gwt-designer
fails to open with message

You are attempting to use UiBinder for ...ui.xml,
however it is not in GWT client package.

compile/running just fine, but gwt-designer is useless, is there a way to
fix it without changing the package -structure ?
thanx
