I registered Gwt-Platform and our next project, our consultant firm. You
should add a category more specific for team of individuals that want to
offer support or consulting services for Gwt.

Great app ! Did you use Gwt-Platform ? :)

Cheers,

Great idea Joe,

I was missing something like this for a long time. But the
categorization is little bit confusing me.
What is the difference between Libraries and Frameworks, or Tools.
Wouldn't it be better to cover some specific domains in the
categories? Like UI widgets, RPC, security, MVP, etc ?

Thank you again.

Hi,

I'm a huge fan of GWT and the only problem I have with it is not
really a problem with GWT but with the fact that there isn't a
centralized place for registering component and associated tools
AFAIK. I have created an application to do this which is available
athttp://gwtmarketplace.appspot.com

This project is open-source and the project and source code is
available at:http://code.google.com/p/gwtmarketplace/.

I encourage everyone who has a product related to GWT to register it
so it easier for folks like myself to see what is available and be
able to comment on and rate these products.

I would certainly appreciate if the GWT folks would link
tohttp://gwtmarketplace.appspot.comtomakeit easier for people to

What I thought you'd do in PhP is something like
$_GET['_escaped_fragment_'], then take that string, unescape it, and you've
got your query params back (your first workaround). But I do see the
problem that it's slightly less convenient... With both of your suggested
workarounds, just remember to unescape the keys and values afterwards. It
*would* be nice to have a handy little parser for this.

kathrin

Correct?

Now, in PHP you normally access the query string data by calls like
$_GET[].
Only in this case if you call $_GET['SEARCHFOR'] you wont get the
value star wars like you normally would, because google bot has
added _escaped_fragment_ to the start of the key value.
You could still get the other key/value pairs just fine following the
sign, but the first one be visible in the normal way.

See the problem?

I've come up with some solutions, but they arn't that pretty.
One way is to remove the _escaped_fragment_ from the start of the
string and make my own parser for the key/value pairs.

The other is to search for $_GET['_escaped_fragment_SEARCHFOR']
instead of SEARCHFOR. However, this results in the query string
needing to be in a fixed order. (or testing for both
_escaped_fragment_** and ** for every key I'm looking for).

Its not a critical problem, as the first workaround works and am
currently using it.

But it does seem like there should be some nice method to be able to
use PHP's query-string functions as intended.

Finally, one last thing; I cant work out any way to tell when my
system is working or not. After a few days my #! results dont seem
googlable...so can I assume it isn't working yet for some reason? (Ive
submitted a sitemap thats parsed over ok...so I expected
something..hmm..)

Thanks, Sorry if its not clear, but I am actually talking about all of

PHP is my back end which is generating the static pages.
GWT is what my site is coded in. Its completely dynamic and makes
extensive use of # tokens to store and retrieve its states.

I'm attempting to get my side Ajax crawl-able using this guide;
http://code.google.com/web/ajaxcrawling/docs/getting-started.html

This guide states to replace the normal #anything style history
tokens with #!anything tokens instead. Note the additional !
When google's crawler is requesting these pages it swaps the #! for
?_escapedfragment_=, allowing the server to generate a static page
using the query string.
This is all laid out in googles guide.

However, the formating of this ?_escapedfragment_= does not allow
php to process the key/value pairs in the query string as it normally
could.
PHP can normally read of key value pairs from the query string using
its $_GET[] command. However, under this system ?_escapedfragment_=
in the url requested prevents the first key value pair being read.
(as the parser now sees _escapedfragment_ as its own key, and the
first true key as its *value*).

Thus, in order to use PHP with Google's system for making Ajax
crawlable, I was querying if GWT user's should add to their new
history token format, rather then just !. So the new tokens become
#! rather then just #!.

This is a little confusing, but I think it should be understandable
for anyone who knows both PHP as well as GWT. (or at least, has used
extensive historytokens/states in their web design).

Finally, I mentioned the Webmaster tools Fetch as Googlebot as thats
what I'm using to test if my site is indeed browse-able by google's
bot. Its not yet possible to use it to test completely for this sort
of functionality, however. So some of this work is a little blind.

Re: Spring Security UI Conditional Rendering

2010-07-27 Thread Peter Simun

Acris has also the client conditional security. Have a look on:
http://code.google.com/p/acris/wiki/SecurityClient

Just annotate you panel with
@Secured(Grants.ROLE_ADMIN)
protected VerticalPanel mainPanel;

and it will displays only to users which has correct security
permission.

You can study more in the showcase:

 has a role such as ROLE_GUEST who is not a ROLE_ADMIN, that user
 should not see the panel

 I would like to do something like:

 I know UI conditional rendering  can be easily accomplished using jsp
 and the Spring Security tags (as shown below). But we don't want to
 use jsp

 sec:authorize access=hasRole('ROLE_ADMIN')

 I've tried the acris securityhttp://code.google.com/p/acris/wiki/Introduction

 not UI conditional rendering. UI conditional rendering ROLES come from
 its own filter
 sk.seges.acris.security.server.SessionRemoteServiceFilter and user

 I've also tried  gwt-incubator

 I've seen some news feed about calling back to Spring Security but
 didn't know how to accomplish the actual calls.

2010-07-27 Thread Thomas Wrobel

Thanks for the clarification.

The problem is, to my knowledge, you can't use the built in parser in
PHP to parse your own strings, it only reads from the URL.
So while you can get the original query string by doing;
$_GET['_escaped_fragment_'], if you got multiple parameters you then
have to parse over it yourself.

And thanks for the unescape reminder!

 If so, are we just outputting the file names to make a suitable

 May I please see your linker code!?!  Is there a manifest linker

Hey Damian,

It doesn't look like that's possible:
http://code.google.com/webtoolkit/doc/latest/DevGuideTestingHtmlUnit.html.
HtmlUnit only supports emulating FF 2, FF 3 and IE 6 - 8. For doing

for doing integration testing that involves some UI components, but
not straight on GUI testing.

  I'm currently struggling with the layout of the main window.  It is
  fairly standard with a nearly static header at the top, fixed height
  status pane at the bottom, hideable navigation window to the left
  (west) and a master/detail form in the middle, and hideable help pane
  to the right (east).  After some investigation and coding, it looks
  likeSplitLayoutPanelmay be what I need, but I have questions:

 Because not all panels should be resizable, I'd rather go with a
 DockLayoutPanel; eventually mixing it with aSplitLayoutPanel:
 DockLayoutPanel for north+south,SplitLayoutPanelin the center with
 resizable east and west regions.

  1) How do I make it so that it properly reacts to window resize
  events?  Do I have to code this myself? Is there a better way?

 Layout panels should handle it automatically, provided you add them to
 the RootLayoutPanel.

  2) Can I get rid of the splitters below the header and above the
  status bar.  If this is not possible, should I just use a
  VerticlePanel and put theSplitLayoutPanelin the middle?

 See above: DockLayoutPanel w/ nestedSplitLayoutPanel.

  3) How do I make it so that the master pane can be dragged and
  dropped below the navigation pane.  This is an important capability
  for users because it allows them to maximize the detail area while
  keeping the master items visible.

 GWT doesn't provide anything for drag'n'drop, though there are 3rd-
 party libs, such as gwt-dnd. But, honestly, it'd probably be a big
 amount of work to plug this into a LayoutPanel...
 If you can, replace DnD with some other interaction: for instance,
 some kind of maximize button to move the master to the west in one
 click.

  4) What kind of pane should I use for the hidable panes?

 If you really want click to hide (or the reverse, click to pin),
 you'd probably rather use a LayoutPanel which has a setWidgetVisible
 method, than a DockLayoutPanel orSplitLayoutPanel(but of course
 you'd lose the splitters). It might be possible to 
 extendSplitLayoutPanelthough and play directly with the LayoutData
 associated with widgets.

  How do I animate the showing/hiding?

 AnimatedLayout (LayoutPanel, DockLayoutPanel,SplitLayoutPanel) panels
 have an animate(int) method.

I'm sorry, the reason for having all those error messages was that I
forgot to put serializer-version.jar and xalan-version.jar into /

Re: Client side caching?

David Chandler wrote a couple of great article on that. Everything is around
Gwt-Dispatch project, but you could also use Gwt-Platform to do the same
thing.

Hi,

I am new to GWT and kinda dealing with the same questions at the
moment. I need user data, basically a User object very often and I
want to get it just once in every request. At this moment multiple
presenters are getting the User and this is obviously bad for
performance.

The solution Feldman suggested sounds right to me, I just have no idea
how to set this up. Could you give me a code example on how to
implement this?

Re: HTML5 Offline GWT APP

2010-07-27 Thread Shawn Brown

 It seems to be working, but debugging is not easy.

Why is that?

Can't you use Firebug, the Error console in Safari or the Dev console
in chrome to display logging?

Sorry if it's a dumb question but ...

Anyway thanks!

Test Data

Hello fellow GWT programmers !

Need some kind of parallel advice here. I need to deliver a GWT
application compiled inside an EAR file, I have managed to assemble my
EAR file correctly and deploy it to a variety of application servers,
but now I'm in a bit of a pickle here. A Client has requested I
deliver my web app with some test data preloaded into the application.
What's the best way to do this with GWT ? Is there a way to emulate a
Database ? Could I use Serialization ? (I have already tried but the
file locations become unpredictable) Could I deliver some sort of
portable Database with my EAR file ?

I expect to read from you soon, and thanks in advance,

Best Regards,

Jose.

Re: client-side deserialization issue of bytecode enhanced classes in dev mode

2010-07-27 Thread Deepak Singh

Can i know how you are using jibx binding with gwt ?

On Tue, Jul 27, 2010 at 2:53 PM, lpetit laurent.pe...@gmail.com wrote:

Hello,

I have a problem in dev mode.
I've made a set of domain classes client-side compatible (the java 2
javascript compiler reports no error).
When I get an instance of a class in the server, it's via jibx. jibx
uses bytecode enhancement in a post-compilation phase, and adds some
fields to the enhanced classes.

So, when I get an instance via jibx, I have hidden fields added by
jibx. Example: jibx_sourceLine.

In dev mode, the instance seems to correctly serialize, but there's
a problem when deserializing : the field added by jibx at bytecode
enhancement time has no counter-part, since it's not in the java
source code of the instance's class.

Moreover, I don't care about these jibx fields in the client side.
They could as well be discarded by the serializer/deserializer
mechanisms, I don't care.

Do you have any idea to help me solve my issue ?

Re: GWT app no longer working in Eclipse 3.6 dev-mode

2010-07-27 Thread googelybear

Hi kathrin,

thanks for the pointers! You were absolutely right, it is related to
SOP. I tried it on IE and there I get a human readable message (The
URL ... is invalid or violates the same-origin sercurity restriction).
It seems that someone - probably by mistake - set the wrong url in a
config file so it's trying to connect to a foreign server directly
instead of going through the proxy servlet. After fixing this it works
again.

thanks again,
Dennis

 Hi Dennis,

 my guess is that this has something to do with the ports you're using for
 DevMode.  A couple of things to try:

 - are you running DevMode in -noserver mode? If so, it could be a Same
 Origin Policy problem.
 - can you confirm that this problem only occurs on Firefox and not on IE?
  AFAIU, this is Firefox-specific.
 - does compiling and deploying your app work fine (even for FF)?

Storing an object at the client during a request

2010-07-27 Thread Julius

Hello,

How can I store an object on the client side during an entire request
and make it accessible to multiple presenters in a MVP application?

I am currently retrieving the User object in a servlet filter and
putting it on the request, like so

// get User by cookie
User user = sercurityService.getCurrentUser();
// Add to request
req.setAttribute(user, user);
// Go ahead
chain.doFilter(req, res);

So, how would I now store it on the client side and access it from my
presenters?

Best, S

enum serialization

2010-07-27 Thread mbstiburon

I have classes with inner enums such as
public class Foo implements java.io.Serializable {
  public enum Status {
ACTIVE, INACTIVE, NA
  }

  private Status status;
  public Foo() {}

  public Status getStatus(){
return this.status;
  }
  
}

When I compile (gwtc), it does not complain; however, I get the
following exception during runtime.

Caused by: com.google.gwt.user.client.rpc.SerializationException: Type
'com.mycompany.gwt.Foo$Status' was not included in the set of types
which can be serialized by this SerializationPolicy or its Class
object could not be loaded. For security purposes, this type will not
be serialized.: instance = ACTIVE
...

Any idea?
Does gwt not able to serialize enums defined as an inner class? Do I
have to create top level enum classes?

BTW, I am using GWT 2.0.3 on OS X.

Any help on this would be greatly appreciated.

Re: Writing a JS library in GWT?

2010-07-27 Thread S Rabin

I see. So when the only thing in my loadModule function is an export
call, and I export the method (via Ray Cromwell's gwt-exporter
library, which I was already using):

public void HelloTest(String id){
 DOM.getElementById(id).setInnerHTML(Hello World);
}

it should compile to 25kb plus a bootloader?  I'm not arguing that a
bootloader is a bad idea for larger code, but I was really just hoping
for a --disable bootloader compile option.

To address your concern that there is 'no possible way for the code
size to grow', and that the GWT compiler aggressively prunes dead
code, yes, I'm fully aware that it is designed to do that.  That's
why, when writing a function in GWT, I expect it to compile out to
something that doesn't exceed the size of handwritten JS for the same
purposes.  There are two options here: one, I'm missing some checkbox
(and it's not the OBFuscated option), or two, GWT is including a lot
more crap it thinks I need that I'm not aware of, hence why I'm asking
how to fix it.

As for whether I know better than Google when it comes to the
bootloader... yes, in this case, I do.  I anticipate this library to
be approximately 10kb of handwritten javascript, and I'm not doing
anything that should warrant more than 1 permutation beyond browser
specific speed optimizations.  Therefore, distributing the library as
a .js file instead of a bootloader plus 4 different permutations seems
like a better idea.

Is my only option here really to write my own linker to output one .js
file, no bootloader, no browser-specific optimizations?

On Jul 26, 12:42 pm, lineman78 linema...@gmail.com wrote:
 First, let me start by saying that people are already writing
 javascript libraries using GWT and have been for some time.  Ray
 Cromwell created the GWT exporter library for this exact purpose for

 it is the only way to deliver the most efficient code to the client.
 There is no possible way for code size to grow when compiled because
 if you go far enough every method will eventually make it to a JSNI
 method, so what you are missing in your calculations is all the code
 supplied by google and the small overhead code involved with the
 bootloader.  However, there is a linker available to create only one
 output, but in order for this to work the compilation must result in
 only one permutation, which is almost impossible unless you know the
 browser your client will be using.  You asked: Is there a way to crop
 out all the unnecessary cruft GWT seems to think I need?.  You can
 write your own linker if you feel that you know better than google
 when it comes to the bootloader, but as far as the compiled code
 itself; the GWT compiler has very aggressive dead code elimination, so
 any output code will be used at some point.

  I've done quite a bit of searching to find any information about this,

  to keep in GWT before compilation.

  I would like to write the libraries I frequently use in my projects in
  GWT, then compile and expose them to hand-written Javascript.  I have
  several issues with the way GWT seems to handle what I want to do:

  1) Bootstrapping.  I understand that the iframe loading method is
  highly efficient for large codebases so as to make the page non-
  blocking, but for a small library bootstrapping is overkill.  To test,
  I tried writing my TableGenerator library (a 7kb handwritten non-
  minified library) in GWT.  The result was a 6 kb deferred binding
  loader file (table.nocache.js) and 4 permutations of compiled JS
  weighing in at 20-30kb each.  Which brings me to issue #2

  2) For compiling the code, GWT seems to produce LARGER codebases.
  Fast, yes, but how does 3-5kb of source result in 20-30kb of compiled
  javascript? Is there a way to crop out all the unnecessary cruft GWT
  seems to think I need?

  3) I would prefer to not have a bootloader - I anticipate the compiled
  form of my code is going to be smaller than the bootstrap code and
  would rather it just be loaded.  Is there a compilation option to
  disable permutations and output (obviously more to handle different
  implementations) code that works in all browsers?

Just going through the UiBinder development guide at

this returns just one containing element. I know this example is to do

about the binding?

You need to have only one container.

IE Bookmarks IFrame src issue.

2010-07-27 Thread Sony

A truly idiotic bunch at Microsoft must have decided this was a great
idea:  If you open an IE Bookmark in a text editor you will see it
records an IFrame's src at the time the bookmark was created.  When
using said bookmark next time around, IE makes a request of the
IFrame's src without even checking if the src for that IFrame has
changed in the newly requested page  so if and only if the
previously recorded src fails to load (either from cache or from
server) does it try loading the new src that the IFrame tag now
carries.

This is actually a major problem for our GWT web-app - as we release
every quarter and we employ GWT's 'perfect caching' strategy i.e.
cache policy of forever for all *.cache.* files.  Both IE6  IE8 end
up requesting and then loading from cache the older version of our
cache.html resulting in various incompatibility exceptions.  For now
we just let users know to delete the bookmark and recreate it in these
types of situations.

Any help in fixing this issue would be appreciated.  I've tried
replacing the iframe-linker with the cross-site linker which works but
then code-splitting is not supported (which we rely on heavily).

Thanks much
Sony

Where can I put a File to be read/write from RPC Servlet ?

Good day everybody,

I have this particular need, where I need to have a file (xml) within
my GWT app. I have some data in this xml I must read, change, and then
write (update)
The file must be delivered or included within the Gwt App. Can anybody
please tell me where can I place this file, so I can read/write it
using java's file APi from an RPC Servlet.

Here's a brief description of how my App's directory structure looks
like:

GwtApp
|__ src
|  |__org
|  |   |__jose
|  | |__client
|  | |__server
|  | |__shared
|  |
|  |__META-INF
|
|__ war
  |__gwtapp
  |__WEB-INF

For my current needs, where would you suggest placing the file ?

Thank you very much in advance,

Have a nice day,

Jose

Re: Writing a JS library in GWT?

2010-07-27 Thread lineman78

Once the GWT compile completes, it is up to the linker to decide how
to package it.  The single script linker should behave how you would
like, but you will have to make sure that deferred binding is never
used in your code unless only one permutation is possible.  The
default linker is an iframe linker, which is the bootloader you are
talking about.  Google knew some people wouldn't like this and would
like to do exactly what you are saying, which is why they maintain the
SingleScriptLinker.  If it doesn't behave exactly as you would like
you may have to pull the source down and modify it to fit your needs.
There needs to be exactly one primary linker, therefore there is no
disable bootloader compile option because a linker must be provided in
order for GWT to know how to distribute and load the code.

 }

 it should compile to 25kb plus a bootloader?  I'm not arguing that a
 bootloader is a bad idea for larger code, but I was really just hoping
 for a --disable bootloader compile option.

 To address your concern that there is 'no possible way for the code
 size to grow', and that the GWT compiler aggressively prunes dead
 code, yes, I'm fully aware that it is designed to do that.  That's
 why, when writing a function in GWT, I expect it to compile out to
 something that doesn't exceed the size of handwritten JS for the same
 purposes.  There are two options here: one, I'm missing some checkbox
 (and it's not the OBFuscated option), or two, GWT is including a lot
 more crap it thinks I need that I'm not aware of, hence why I'm asking
 how to fix it.

 As for whether I know better than Google when it comes to the
 bootloader... yes, in this case, I do.  I anticipate this library to
 be approximately 10kb of handwritten javascript, and I'm not doing
 anything that should warrant more than 1 permutation beyond browser
 specific speed optimizations.  Therefore, distributing the library as
 a .js file instead of a bootloader plus 4 different permutations seems
 like a better idea.

 Is my only option here really to write my own linker to output one .js
 file, no bootloader, no browser-specific optimizations?

  There is no possible way for code size to grow when compiled because
  if you go far enough every method will eventually make it to a JSNI
  method, so what you are missing in your calculations is all the code
  supplied by google and the small overhead code involved with the
  bootloader.  However, there is a linker available to create only one
  output, but in order for this to work the compilation must result in
  only one permutation, which is almost impossible unless you know the
  browser your client will be using.  You asked: Is there a way to crop
  out all the unnecessary cruft GWT seems to think I need?.  You can
  write your own linker if you feel that you know better than google
  when it comes to the bootloader, but as far as the compiled code

  any output code will be used at some point.

Re: iframe JS code linker

2010-07-27 Thread opichals

Hi!

Thanks for the answer!

I didn't even mention the sandbox environment as that seemed quite
obvious at the first sight. But I was kind of thinking to read about
some JS codebase size related advantages that could be implied... The
caching issues are definitely interesting, but that's not a reason for
a separate JS code iframe on its own.

  Commonly JS frameworks' .js files are simply added to the .html file

  to having that separateiframefor the generated JavaScript

  I can imagine it is useful for modularization reasons... basically to
  simplify the application linker and HTML generation process.

  I fail to see any other reason for this. Is it just the linker reason
  or is there some other e.g. performance benefit or something that
  would be further motivation to have the JS code in a separateiframe?

 There are two reasons IIRC:
  -iframegives you a sandbox for free, so you don't mess with other
 scripts in the web page *and* they don't mess with your script (note
 that the XS linker uses the module pattern, so it shouldn't a
 problem either, except maybe when you also use runAsync)
  - some browsers (particularly those coming from Redmond) won't cache
 gzipped *.js files coming from SSL/TLS, but will cache *.html (this is
 from memory, it might be unrelated to gzipping or to SSL/TLS, but it's
 at least one of those)

Re: Where can I put a File to be read/write from RPC Servlet ?

2010-07-27 Thread dane.molotok

I guess I'm missing something in the question. Have you tried some
things and it's not working like you'd expect? I would think you could
put it in src/org/jose/server.

 Good day everybody,

 I have this particular need, where I need to have a file (xml) within
 my GWT app. I have some data in this xml I must read, change, and then
 write (update)
 The file must be delivered or included within the Gwt App. Can anybody
 please tell me where can I place this file, so I can read/write it
 using java's file APi from an RPC Servlet.

 Here's a brief description of how my App's directory structure looks
 like:

 GwtApp
             |__ src
             |          |__org

             |
             |__ war
                       |__gwtapp
                       |__WEB-INF

 For my current needs, where would you suggest placing the file ?

 Thank you very much in advance,

 Have a nice day,

 Jose

Re: Why does GWT+JUnit take so long to start?

2010-07-27 Thread Miroslav Genov

 I suggest you to take a look into MVP pattern. It will speed things 
up. About the UI interface and visualization, you can take a look into a 
webdriver or selenium. Both of them may test user interactions with the UI.

Re: GWT 2.1 how to customize style for TextColumn

2010-07-27 Thread Ted

Hi Christian,

Thanks for the link.  The Column object doesn't appear to have a way
to set the style.  There are no setStyleName or addStyleNames methods
to call as in UIObject.  I am hoping there is an alternative way but I
cannot discover it yet.

Thanks,
Ted

Re: GWT 2.1 how to customize style for TextColumn

You're right, but if a row can have his style changed, I bet a Cell can too.

Give me 10 minutes, I'll do a fast check, I'm also right into this stuff
right now.

Re: GWT 2.1 how to customize style for TextColumn

Ok, in CellTable you have a function for this : ct.addColumnStyleName().
That would change the column number.

But need more infomrations, you want to set the style of a single cell or of
an entire row ?

Re: GWT 2.1 how to customize style for TextColumn

2010-07-27 Thread Ted

Hi Christian,

When I override the render object of Column I can nest a span inside
the td for that cell.  This way I can control the style of the
span.  However if there is a way to control the style of the td I
would be interested in what you can discover.

Thanks,
Ted

Re: Where can I put a File to be read/write from RPC Servlet ?

Hello dane !

You're right in assuming something it's not working. Here's the
thing... I need to read from the xml file so I can perform some
operations on it and then save it again, here's the code I'm trying to
get to work:

import 

public class GreetingServiceImpl extends RemoteServiceServlet
implements
GreetingService {
public String greetServer(String input) throws
IllegalArgumentException {

FileInputStream fin;

try {
fin = new FileInputStream (users.xml);
System.out.println( new DataInputStream(fin).readLine() );
fin.close();
} catch (IOException e) {
System.err.println (Unable to read from file);
System.exit(-1);
}
return success reading file;

}
}

And here's the exception I'm getting:

Unable to read from file
.
.
.
Caused by: java.security.AccessControlException: access denied
(java.lang.RuntimePermission exitVM.-1)

This last test was performed putting the file where you suggested.
(src/org/jose/server. )

Thank you very much,

my GWT app. I have some data in this xml I must read, change, and then
write (update)
The file must be delivered or included within the Gwt App. Can anybody
please tell me where can I place this file, so I can read/write it
using java's file APi from an RPC Servlet.

Here's a brief description of how my App's directory structure looks
like:

GwtApp
            |__ src
            |          |__org
            |          |       |__jose
            |          |                 |__client
            |          |                 |__server
            |          |                 |__shared
            |          |
            |          |__META-INF
            |
            |__ war
                      |__gwtapp
                      |__WEB-INF

For my current needs, where would you suggest placing the file ?

Thank you very much in advance,

Have a nice day,

Jose- Hide quoted text -

Re: IE Bookmarks IFrame src issue.

2010-07-27 Thread Sony

Greg, you understand correctly.  IE attempts to load the
older.cache.html that was recorded as the src of the iframe when the
page was bookmarked instead of the src as it exists currently on the
requested page resulting in incompatibility exceptions with the newer
version on the server.  The older.cache.html still resides in IE cache
as it was sent with a cache header equivalent of forever.

 Can they do that ONLY for IE 6  8?  Because it doesn't look like they

  You can set the cache properties using .htaccess or, if you control the
  httpd server, in that software's domain settings.

Web service call

2010-07-27 Thread Deepak Singh

Hi,

With GWT 2.1

My requirement is, I have to connect to different airlines thorugh their web
services at the same time to search for available flights and then display
the search result on my page.response
I have wsdl files for all of them and methods to invoke and set request as
xml string and get response as xml string. I have to do this search very
very fast to get the response in 2 seconds from all the airlines. Kindly
suggest the best approach to follow.
If possible provide some sample code.

Regards
Deepak

Re: Cache on Client

2010-07-27 Thread Stefan Bachert

Hi,

GWT is putting javascript into the browser cache.
Data which are coming from GWT-RPC do not went into the browser cache.

However, a client data cache (programmed in java/javascript) greatly
improves the data loading by avoiding duplicate requests.
I do not see a security hit from doing so.
Even a browser cache is no security hit as long the user account of
the operating system is not shared.

 these information should only be sent to the client only when

Re: Where can I put a File to be read/write from RPC Servlet ?

Hi skippy !

I have tried your suggestion but unfortunately it did not work :(

I changed the java APIs I used this time but the result is the same:
...
  try {
File f = new File(xml/users.xml);
FileReader reader = new FileReader(f);
BufferedReader buffer = new BufferedReader(reader);
buffer.readLine();
// Read a line of text
System.out.println(buffer.readLine());
}


The generated exception is:

Caused by: java.security.AccessControlException: access denied
(java.io.FilePermission \users.xml read)

also, If I try it like this: /xml/users.xml with the forward slash a
the beginning it goes for the root of the system which is C:/ and it
still does not work, which I find weird because that's outside the
application's context, right ?

Anyways, please help me Skippy.

Sincerely,

Jose.

Re: Writing a JS library in GWT?

2010-07-27 Thread Sripathi Krishnan


 That's why, when writing a function in GWT, I expect it to compile out
 to something that doesn't exceed the size of handwritten JS for the
 same purposes.

Compiling Java to Javascript has some overheads which you cannot get rid off
easily. These overheads are not much if you are building a web-application;
but it could prove expensive if you are building a general purpose js
library.

*Overhead 1 : IFrame Bootstrap loader*
As lineman78 suggests, you could use the built-in SingleScriptLinker, or you
could write a custom linker (not too difficult). But this isn't the bulk of
the overhead.

*Overhead 2 : Java emulation in javascript*
GWT has to emulate java.lang and java.util packages for you in javascript.
Every class that you write will typically have the following four methods -
getClass(), toString(), equals() and hashcode() in javascript - even if you
don't actually invoke those methods. Besides, there are overheads with the
collections emulation. You cannot write a linker to overcome this overhead.
I believe GWT team is working on a simpler collections emulation, and that
would reduce the overheads - but till then I am afraid you don't have an
option.

The only thing I can suggest is -*XdisableClassMetadata *flag to reduce some
of the overheads.

 Once the GWT compile completes, it is up to the linker to decide how
 to package it.  The single script linker should behave how you would
 like, but you will have to make sure that deferred binding is never
 used in your code unless only one permutation is possible.  The
 default linker is an iframe linker, which is the bootloader you are
 talking about.  Google knew some people wouldn't like this and would
 like to do exactly what you are saying, which is why they maintain the
 SingleScriptLinker.  If it doesn't behave exactly as you would like
 you may have to pull the source down and modify it to fit your needs.
 There needs to be exactly one primary linker, therefore there is no
 disable bootloader compile option because a linker must be provided in
 order for GWT to know how to distribute and load the code.

  To address your concern that there is 'no possible way for the code

  more crap it thinks I need that I'm not aware of, hence why I'm asking
  how to fix it.
 
  As for whether I know better than Google when it comes to the
  bootloader... yes, in this case, I do.  I anticipate this library to
  be approximately 10kb of handwritten javascript, and I'm not doing
  anything that should warrant more than 1 permutation beyond browser
  specific speed optimizations.  Therefore, distributing the library as
  a .js file instead of a bootloader plus 4 different permutations seems

Thanks.

Yes, i was thinking about see some libs to inspire myself. The trouble

I think that the next week i could start trying to do it.

Re: Tree Padding

Something like that happened to me.

What i did was the following.

For example:

Play with padding and margin and it could help you.

Re: JNDI datasources in GWT 2.1.0 M2 hosted mode

2010-07-27 Thread Y2i

Hi Lukateake,

Have you been able to solve your problem?

I have a simpler problem of configuring JNDI in GWT 2.0.3.  My
Configure class=org.mortbay.jetty.webapp.WebAppContext/ looks
exactly as yours (that works under M1), except it uses postgresql
driver.

Configure class=org.mortbay.jetty.webapp.WebAppContext

Set 
name=urljdbc:postgresql://localhost/testDb/Set
Set name=usernameuser/Set
Set name=passwordpassword/Set
/New
/Arg
/New
/Configure

When I ran the application in eclipse, I'm getting the following
error:

java.lang.ClassNotFoundException:
org.mortbay.jetty.plus.naming.Resource
at java.lang.ClassLoader.findClass(ClassLoader.java:359)
at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
...

It looks like there is no problem locating
org.mortbay.jetty.webapp.WebAppContext, but
org.mortbay.jetty.plus.naming.Resource cannot be found.

I tried to modify -classpath to point to jetty-plus-6.1.23.jar, but it
didn't help, same error.

Would really appreciate yours or someone else's advice on how to make
JNDI work with GWT 2.0.3.

Thanks in advance!

Re: Writing a JS library in GWT?

2010-07-27 Thread André Moraes

I had the same problema of getting bigger source code files.

The solution: Check your Module file (Module.gwt.xml).

As the default behavior is to create GUI the default module loads the User
module and this module has a lot of code that you don't use when creating
non GUI libraries/applications.

In my case I wrapped the json.org json functions (JSON.stringify e
JSON.parse) into a GWT module. Since the modern browsers has those functions
built-in i used deffered binding so the code was download only for IE 6 
 7.

In my case all my code was removed from the permutation for moderm browser
and the total download was only ~4KB and the code for IE 6/7 was 7KB (3KB
for the mimified version of json.org).

Most of the 4KB was jre emulation, wich will be required (and download only
once) no matter how many libraries you use. That's why all libraries in GWT
must go with the Java code in the JAR.

When using GWT you will use it to develop larger apps, so this 4KB overhead
is minimal (or you known some javascript framework which uses less than 4KB
in the minimal version?)

if your library is so small you should consider writing it in plain
javascript, but if you want to use it as a GWT library the final overhead in
the application will be very small.

 Compiling Java to Javascript has some overheads which you cannot get rid
 off easily. These overheads are not much if you are building a
 web-application; but it could prove expensive if you are building a general
 purpose js library.

 *Overhead 1 : IFrame Bootstrap loader*
 As lineman78 suggests, you could use the built-in SingleScriptLinker, or
 you could write a custom linker (not too difficult). But this isn't the bulk
 of the overhead.

 *Overhead 2 : Java emulation in javascript*
 GWT has to emulate java.lang and java.util packages for you in javascript.
 Every class that you write will typically have the following four methods -
 getClass(), toString(), equals() and hashcode() in javascript - even if you
 don't actually invoke those methods. Besides, there are overheads with the
 collections emulation. You cannot write a linker to overcome this overhead.
 I believe GWT team is working on a simpler collections emulation, and that
 would reduce the overheads - but till then I am afraid you don't have an
 option.

 The only thing I can suggest is -*XdisableClassMetadata *flag to reduce
 some of the overheads.

 Once the GWT compile completes, it is up to the linker to decide how

 like, but you will have to make sure that deferred binding is never

 default linker is an iframe linker, which is the bootloader you are
 talking about.  Google knew some people wouldn't like this and would
 like to do exactly what you are saying, which is why they maintain the
 SingleScriptLinker.  If it doesn't behave exactly as you would like
 you may have to pull the source down and modify it to fit your needs.
 There needs to be exactly one primary linker, therefore there is no
 disable bootloader compile option because a linker must be provided in
 order for GWT to know how to distribute and load the code.

GWT Distrubted Compiler Project

2010-07-27 Thread Dobes

Hi,

I've been working on a distributed compiler project, to speed up
compile times by distributing the work across many machines.  Useful
for those times when the compiler takes a long time and you have a lot
of permutations.

Since its a bit of a side-project I'm hoping some other will jump on
board and help out.

This project provides an AppEngine? based server and java clients that
distribute GWT permutation compiles automatically over participating
computers.

Symmetric keys are used to protect the privacy of your data.

How it works:

 1. The team agrees on the queue ID and symmetric key for their builds
 2. They select or deploy the server
 3. They run any number of build slaves and configure them to watch
that queue on that server
 4. When building, they use the DistCompile? class to compile instead
of the Compile class
 5. DistCompile? does a pre-compile (non-permutation specific), then
uploads the results to the central server on AppEngine?
 6. Build Slaves who are polling the server download the precompiled
file and perform a permutation compile, then upload the results to the
server again
 7. The compile client downloads build results until it has all the
permutations
 8 . Then it runs Link with the results and your build is done,
hopefully faster than if you did it all locally

The best use case for this is if you have a few extra PCs and want to
do your work on a laptop or something without a lot of memory/CPU.
For example, one of my co-workers is taking 40 minutes to build our
GWT stuff; I'm hoping this can bring it down to 5-10 minutes instead.

Please contact me if you're willing to help with:

 1. Suggestions (file them in the issue tracker)
 2. Patches (put them in the issue tracker, too)
 3. Active Development (be happy to give you contributor access)
 4. Testing (file the bugs ...)

Re: Writing a JS library in GWT?

2010-07-27 Thread André Moraes

Correction on my last post.

The module load is required by the user.agent property.

But the output from the compiler remove the GUI code from the library when
compiled, you must remove the line which imports the Standard style so the
images  for borders and other things will no go in the output.

My GWT_Json.gwt.xml looks like this:

?xml version=1.0 encoding=UTF-8?
module rename-to='gwtjson'
  !-- Inherit the core Web Toolkit stuff.--
  inherits name=com.google.gwt.user.User/

  !-- Inherit the default GWT style sheet.  You can change   --
  !-- the theme of your GWT application by uncommenting  --

  !-- inherits name='com.google.gwt.user.theme.standard.Standard'/ --
  !-- inherits name='com.google.gwt.user.theme.chrome.Chrome'/ --

  !-- Other module inherits  --

  !-- Specify the app entry point class. --
  entry-point class='br.com.gwtjson.client.GWTJson'/

  !-- Deferred Binding - Some browsers have a native implementation of

  code, we can use the native (and fast) implementation.

Symmetric keys are used to protect the privacy of your data.

How it works:

1. The team agrees on the queue ID and symmetric key for their builds
2. They select or deploy the server
3. They run any number of build slaves and configure them to watch
that queue on that server
4. When building, they use the DistCompile? class to compile instead
of the Compile class
5. DistCompile? does a pre-compile (non-permutation specific), then
uploads the results to the central server on AppEngine?
6. Build Slaves who are polling the server download the precompiled
file and perform a permutation compile, then upload the results to the
server again
7. The compile client downloads build results until it has all the
permutations
8 . Then it runs Link with the results and your build is done,
hopefully faster than if you did it all locally

The best use case for this is if you have a few extra PCs and want to
do your work on a laptop or something without a lot of memory/CPU.
For example, one of my co-workers is taking 40 minutes to build our
GWT stuff; I'm hoping this can bring it down to 5-10 minutes instead.

Please contact me if you're willing to help with:

1. Suggestions (file them in the issue tracker)
2. Patches (put them in the issue tracker, too)
3. Active Development (be happy to give you contributor access)
4. Testing (file the bugs ...)

Thanks in advance!

  Hi,

  I've been working on a distributed compiler project, to speed up
  compile times by distributing the work across many machines.  Useful
  for those times when the compiler takes a long time and you have a lot
  of permutations.

  Since its a bit of a side-project I'm hoping some other will jump on
  board and help out.

  This project provides an AppEngine? based server and java clients that
  distribute GWT permutation compiles automatically over participating
  computers.

Love your idea... even compiling a medium project in a macbook right now is
a pain in the ass.
I am out of time right now but I will love to help in a near future
