Hi,

I want to build a website with (Home, about, products, ...) menu. I
need to build multiple forms (panels), each panel corresponds to one
menu item, e.g. aboutPanel for about menu item, productsPanel for
products...

Moreover, I would like to implement that panel in terms of RPC
services; I need to correspond each panel to a single RPC service that
communicates with the server to get its data, build the whole form,
and return the result as a panel to be displayed somewhere in the home
page (for example).

Of course, GWT allows us to define multiple services and add multiple
servlet path=/service ... to the module XML file.

My problem is how to know which service should I instantiate depending
on the URL mapping, i.e. suppose that the menu is defined as follow:

div id=menu
a href=index.htmlHome/a
a href=/aboutAbout us/a
a href=/productsProducts/a
...
/div

So when someone clicks the About us link, the URL would be http://
domain/about. So I should instantiate the about service and create
an aboutPanel to display it. The same thing when s/he clicks the
Products link, then the URL is http://domain/products; and, in this
case, I should build the product panel...

So, is there somewhere in GWT application that I could parse the URL
and depending on the mapping portion of it /about or /products
could I decide which service to instantiate? Or is there another
better way to do that?


Thank you very much in advance.

Re: clicking outside the TreeItem firing onTreeItemSelected event

2008-11-05 Thread Litty Preeth

Hi Walden,

I tried using gwt-1.5.2 and gwt-1.5.

If gwt-1.5.2 is used on IE6 it happens only for the child node. Root level
nodes are working fine. But on IE7 and Firefox it is reproducible for all
the nodes.

If gwt-1.5 is used on IE6 everything works fine. But on Firefox it is
reproducible for all the nodes.

You can use this code below to reproduce the issue.

TreeTest.java

import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.RootPanel;

import com.google.gwt.user.client.ui.TreeListener;

/**

public class TreeTest implements EntryPoint {

Tree myTree;

/**

public void onModuleLoad() {
myTree = new Tree();
for (int i = 0; i  10; i++) {
TreeItem prItm = new TreeItem(Parent_ + i);
TreeItem chItm = new TreeItem(Child_ + i);
prItm.addItem(chItm);
myTree.addItem(prItm);
}
myTree.addTreeListener(treeListener);
RootPanel.get().add(myTree);
}

TreeListener treeListener = new TreeListener() {
public void onTreeItemSelected(TreeItem item) {
Window.alert(item.getText() +  selected);

Re: can the gwt compiler compile files outside the module

2008-11-05 Thread walden


AB,

You could go that way.  Cobbling together a module using a script will
defeat some of your IDE features, though, depending on what IDE you
use.

GWT Modules are transparent and non-intrusive to javac compiling, so
you should be able to accomplish what you need with a small number
(one?) of gwt.xml files strategically placed in your existing
hierarchy.  If I were you, I would probably refactor for GWT/Java
reuse, though.  Take your util files, put them together somewhere in
GWT module arrangement, include that location on the javac classpath
if not already there, and inherit the module wherever your GWT code
needs util services.

It's not necessary for every Module to have an entrypoint.  It's
necessary that the transitive closure of inherited modules for a given
compile have an entrypoint.

Hope this helps,

Walden

Re: Single application .. multiple RPC services


Hi,

Okay, then how could I switch between my services when I click on one
link?
I mean, on the website's home page load, I will instantiate the
default service (let's say homeService). Then on About Us link I
have to switch to the aboutServie how could that switch be done? Is
it enough to pass the /about at the end of the URL?

Re: Response from Server is very slow


Hi,

The short answer is don't fetch even 500 records in one go from the
server - you should use a paging table of some sort. e.g.

   Hi Alex,
   Well here are my concerns on both areas but before I get to that I'd
   like to mention that I'm developing I guess a relatively small module
   but something I think is complex in terms of the amount of
   functionality its providing. The idea is to have a table of data that
   is retrieved from the server and displayed to the user

   1) The data should be sortable/pageable
   2) When the user clicks on a cell/row:
       - the row gets highlighted
       -  the info of that row shall appear in a editable row below the
   table where once the user makes and changes, these are reflected in
   the main table
       - once the user navigates to another row, the edited row should
   have some sort of marker displaying that it is dirty until the save
   button is clicked ( this is allowing for batch processing)
      - thus when a user decides to sort/page this information would need
   to be retained until the user saves.
   3) The user has a drop down above the table to filter by a couple of
   the columns.
   So far not a problem with both of them.

   I looked at ext-GWT and GWT-ext. Both seem are somewhat ok about this,
   however with ext-GWT
   - You can't paginate/sort on the client side if I'm not wrong and the
   whole model seems to force you to do remote pagination which from what
   I saw, would basically reset the data each time - so not a good option
   You can sort on the client side - it's per default that way if you
   want to sort only the current page - in case you want to sort the
   whole data and then have a page Nr. N, you will have to sort/page on
   the server. New grid supports editing directly in the cells(so no page
   refresh necessary). But i haven't used it yet.

   And with GWT-ext:
   I tried implementing it however, ran into some memory overflow problem
   when trying to compile it. Plus, there was a file PagingMemoryProxy
   that was not available in the GWT-ext library but then I later found
   it in the gwtux library. Not sure why it is like that.
   I do not use GWT-ext. The whole javascript-wrapper concept isn't the
   best idea imho.

   On the whole the problem with both ideas is that, I thought of them
   more as widgets but turns out they almost completely take over your
   code with a whole bunch of different things to do as opposed to
   standard GWT code. So, that isn't really an attractive idea.
   Well, i found out that writting smth. as complex as Ext-GWT's grid
   would take too much time and effort - can't really afford it in my
   project. Using existing widgets bring some problems, mostly due to the
   specific nature of your particular application, but they are solvable
   and you need much less time for it.

   Alex,
   What were the problems you found with PagingScrollTable? Just curious
   to know since I'm trying to get an idea of what I might need/ not
   need.
   Bugs, bugs and one more time bugs. Imho you'll need far more time
   solving problems/fixing bugs with PagingScrollTable than doing same
   thing with Ext-GWT's grid. But if you decide to write your own grid,
   then using/rewriting/fixing PagingScrollTable might be a good
   approach.

   Thanks

What part of fetching is taking them most time? Reading from the DB?
Creating POJO-Classes? Sending data? Profile your code, find out which

There's a demo in the Incubator that you could look at. The code for
it can be viewed online or you can download and setup the Incubator
project locally (be sure to grab GWT 1.5.3 if you don't already have
it). Links below.

Hi Issac,
Since I'm still at a design level choosing my options, can I get a
sample code for the PagingScrollTable to be able to evaluate its use
for my purpose? I tried looking at the wiki for the incubator and all
there was was a definition for some bean.

Thanks

Well, i started with trying to use 1.4 Table with 1.5 RCx GWT and

work, but it didn't play nice in my prety complex GUI layout with a
lot of Panels: size and visibility issues. In comparison to it, a Ext
GWT table was a half an hour work and it works prety stable. Basicaly
you can see all my issues when you look at the comments on the

before me and the was no response to it, and because the project

Hi Alex,
Well here are my concerns on both areas but before I get to that I'd
like to mention that I'm developing I guess a relatively small module
but something I think is complex in terms of the amount of
functionality its providing. The idea is to have a table of data that
is retrieved from the server and displayed to the user

1) The data should be sortable/pageable
2) When the user clicks on a cell/row:
- the row gets highlighted
- the info of that row shall appear in a editable row below the
table where once the user makes and changes, these are reflected in
the main table
- once the user navigates to another row, the edited row should
have some sort of marker displaying that it is dirty until the save
button is clicked ( this is allowing for batch processing)
- thus when a user decides to sort/page this information would need
to be retained until the user saves.
3) The user has a drop down above the table to filter by a couple of
the columns.
So far not a problem with both of them.

I looked at ext-GWT and GWT-ext. Both seem are somewhat ok about this,
however with ext-GWT
- You can't paginate/sort on the client side if I'm not wrong and the
whole model seems to force you to do remote pagination which from what
I saw, would basically reset the data each time - so not a good option
You can sort on the client side - it's per default that way if you
want to sort only the current page - in case you want to sort the
whole data and then have a page Nr. N, you will have to sort/page on
the server. New grid supports editing directly in the cells(so no page
refresh necessary). But i haven't used it yet.

And with GWT-ext:
I tried implementing it however, ran into some memory overflow problem
when trying to compile it. Plus, there was a file PagingMemoryProxy
that was not available in the GWT-ext library but then I later found
it in the gwtux library. Not sure why it is like that.
I do not use GWT-ext. The whole javascript-wrapper concept isn't the
best idea imho.

On the whole the problem with both ideas is that, I thought of them
more as widgets but turns out they almost completely take over your
code with a whole bunch of different things to do as opposed to
standard GWT code. So, that isn't really an attractive idea.
Well, i found out that writting smth. as complex as Ext-GWT's grid
would take too much time and effort - can't really afford it in my
project. Using existing widgets bring some problems, mostly due to the
specific nature of your particular application, but they are solvable
and you need much less time for it.

Alex,
What were the problems you found with PagingScrollTable? Just curious
to know since I'm trying to get an idea of what I might need/ not
need.
Bugs, bugs and one more time bugs. Imho you'll need far more time
solving

Re: clicking outside the TreeItem firing onTreeItemSelected event

2008-11-05 Thread walden


Litty,

Yeah, I see it now.  It looks as if this is by design.  If you need an
area to the right of the Tree (outside the Tree but inside the
ScrollPanel) where you can click without selecting a TreeItem (why?),
then you can probably achieve that by setting the Tree's width so it
does not fill the width of the ScrollPanel.  What effect are you
trying to achieve?

Create a stopwatch

2008-11-05 Thread sitaro


Hello!

I need to create a stopwatch. All I need is to have a button to start
and a button to stop, the start button click event will capture a time/
timestamp, the stop button event will capture another one. all I have
to do is to subtract both imes and show it like hh:mm:ss. I guess it
must be quite easy, but I'm having so much problems. Here's a resume
of my code:

-
//In the start event
Date start = new Date();

...
//In the stop event
Date stop = new Date();

// When showing the time
Date result = new Date(stop.getTime() - start.getTime());
DateTimeFormat dateTimeFormat = DateTimeFormat.getFormat(hh:mm:ss);
Window.alert(dateTimeFormat.format(result));
-

It doesn't work. I tried with long values instead of Dates...

-
//In the start event
long start = System.currentTimeMillis();

...
//In the stop event
long stop = System.currentTimeMillis();

// When showing the time
long result = stop - start;
Window.alert(long);
-

Both ways I got crazy results... Please, can anybody help me? Thank
you very much.

How to create layout?

DockPanel header = new DockPanel();
header.add(clientImageBundle.firstmileLogo().createImage(),
DockPanel.WEST);
header.add(helpLink, DockPanel.EAST);

But it doesn't work.

An update on the RPC communication stops functioning when running with Internet Explorer issue

2008-11-05 Thread PJ


Hi,
this is an update on the RPC communication stops functioning when
running with Internet Explorer issue (http://groups.google.com/group/
Google-Web-Toolkit/tree/browse_frm/thread/2f7f9816e0578e0c/

follow up at
http://groups.google.com/group/Google-Web-Toolkit/tree/browse_frm/thread/bcd4438cff88ccf1/d9219c153c3143b6?hl=enrnum=1_done=%2Fgroup%2FGoogle-Web-Toolkit%2Fbrowse_frm%2Fthread%2Fbcd4438cff88ccf1%3Fhl%3Den%26#doc_d9219c153c3143b6

1. Using GWT 1.5 did not solve the problem

2. I experience a problem that is specific to Internet Explorer 6 and
7. I have, despite numerous efforts, not been able to reproduce this
problem with Firefox, Safari or Opera.

3. Sometimes the corrupted requests results in
javax.servlet.ServletException: Client did not send nnn bytes as
expected, but in some rare cases also in

ALLVARLIG: Exception while dispatching incoming RPC call
java.io.IOException
at
org.apache.jk.common.JkInputStream.receive(JkInputStream.java:199)
(full stack trace below)

4. This happens when sending repeated similar requests updating state
from server. It does not matter if this is done using a Timer sending
repeated requests or by scheduling a new request in the callback. RPC
communication is broken anyhow.

I have tried different different servers and different ISP:s, but the
problem seem to come back every time. This application is fairly
simple and straightforward and with IE being the most common browser,
are really this few having this problem ?

I will try to strip the application down keeping this problem and
hopefully someone would care to investigate it further?

 I've tried next approach:

 DockPanel.WEST);
         header.add(helpLink, DockPanel.EAST);

 But it doesn't work.

 Can anyone help me?

Re: Create a stopwatch


Hi Sitaro,

if you happen to be declaring the start and stop Dates locally in your
onClick methods, it probably won't work.

Have you tried:

// in your parent class somewhere
Date start,stop;

then in your onClick's... (note removal of type declarations)

 //In the start event
 start = new Date();

 ...
 //In the stop event
 stop = new Date();


[A null Date returns zero which corresponds to about 1/1/1970 - an
awful lot of milliseconds ago.]

gregor

 Both ways I got crazy results... Please, can anybody help me? Thank
 you very much.

Re: clicking outside the TreeItem firing onTreeItemSelected event

2008-11-05 Thread Litty Preeth

Walden,

But then a user will expect to select a tree node by clicking on the node
only rite? I dont feel that the node getting selected when you click else
where is an expected behavior.

 Litty,

 Yeah, I see it now.  It looks as if this is by design.  If you need an
 area to the right of the Tree (outside the Tree but inside the
 ScrollPanel) where you can click without selecting a TreeItem (why?),
 then you can probably achieve that by setting the Tree's width so it
 does not fill the width of the ScrollPanel.  What effect are you
 trying to achieve?

GWT Json + requestBuilder questions

2008-11-05 Thread newlis


Hello ,
the last weeks i have started using Gwt technology and i have to admit
that is fascinating!! because of lack of examples, i have some
questions.

first of all , i m facing a compilation error.

I did include  inherits name=com.google.gwt.http.HTTP /
in the gwt config file but when i m trying to compile i get

Removing units with errors
   [ERROR] Errors in 'file:/home/tower/Book/G-example/src/org/example/
client/ajson.java'
  [ERROR] Line 45: RequestBuilder cannot be resolved to a type
  [ERROR] Line 45: RequestBuilder cannot be resolved to a type

  [ERROR] Line 56: Request cannot be resolved to a type
  [ERROR] Line 61: Request cannot be resolved to a type
  [ERROR] Line 61: Response cannot be resolved to a type


Secondly , i m trying to make an example reading a json file. If i put
the json file in the same folder as ./example-shell then i do that:
RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST,GWT.getModuleBaseURL() +
file.json);

otherwise
i just put the url ( located in a local server ? )

RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);

try {
  Request response = builder.sendRequest(null, new
RequestCallback() {
public void onError(Request request, Throwable exception) {
  // Code omitted for clarity
}

public void onResponseReceived(Request request, Response
response) {
  JSONArray results;
  results = maketree(response.getText());
}
  });
} catch (RequestException e) {
  // Code omitted for clarity
}

Is this algorithm correct???
also is there any function like maketree that reads the object and
makes it in a tree format ??
ty in advance.

Re: Response from Server is very slow

2008-11-05 Thread Peter D.


It is most likely the serialization and de-serialization that is
taking the most time. There really isn't anything you can do about
this because it's the way XML-RPC works. It converts all your objects
into a really big string (xml) sends it over to the clients which then
re-instantiates the objects on the javascript side. You need to limit
the complexity and size of your objects when using XML-RPC.

At least, I think I am correct. :)

Re: gwt deployment with ant

2008-11-05 Thread Isaac Truett


Sure.

First, you're going to want to compile your application. If you have a
Java backend then you'll want to javac your server-side and common
(shared by client and server) class. Then you'll want to compile your
GWT client with GWTCompiler. You can find previous discussions about
doing this on the forum here. I also wrote about GWT compilation with
Ant, and specifically a custom Ant task that I wrote for invoking
GWTCompiler, here:

http://publicint.blogspot.com/2008/10/introducing-gwtcompilertask.html

Next, if you're using a Java backend, you'll probably be building a
.war file from the compiler output. The easiest way to do that with
Ant is the war task. For other backends, you'll probably want to
zip the compiler output for transfer to the server.

The last step, actual deployment, depends on your server environment.
Several Java app servers have custom Ant tasks for deploying
applications and you can refer to documentation from your app server
vendor to learn more about that. On the other hand, if all you're
trying to do is deploy to a Tomcat instance in your development
environment, it's as simple as copying your .war file into the
tomcat/webapps directory. Deploying to a non-Java backend will
probably involve transfering your .zip file to the server and
unzipping it in a directory configured as a web application root.

The best resource for general help with Ant tasks, in my opinion, the manual:
http://ant.apache.org/manual/

state of hibernate + GWT 1.5

2008-11-05 Thread David Durham, Jr.


Hi all,

What's the state of things with Hibernate and GWT 1.5.  I've done some
quick googling and I see reference to the following:

1 - hibernate4gwt
2 - Making hibernate persistent collections GWT serializable
3 - Just writing your pojo copy utility perhaps using beanlib

I'm wondering if there is one route that is the preferred/recommended
way to go with this issue.

Thanks in advance,
Dave

Migrating from gwt 0.0.2415 to 1.5.3

2008-11-05 Thread Anti


I need the experts´ opinion.

I am trying to carry out the mentioned migration, I have found several
issues and I am wondering if it would be easier to rewrite most of my
components instead of fixing issues line by line, what do you think?

One example of my issues:

setAnimationType(AnimationType.CENTER);

This instruction is repeated through the entire project, it does not
compile because AnimationType.CENTER was public before, now it's not,
an it doesn´t have any accessor method!

Thanks!

Re: layout problem, panel size ignores setCellHeight(50%) ?

2008-11-05 Thread JohnMudd


I'm back.  I looked at gwt-ext but that doesn't look like a good
alternative for me.  I was having good luck with layouts, the demo
page http://www.gwt-ext.com/demo/ is impressive but I would only
recommend gwt-ext it you are absolutely sure you'll never need to
deviate from the sample code in the demos.  No deviation at all.
Things that are easy with GWT (such as making a composite with an
Image and a Label) don't mesh well with gadgets like the gwt-ext
grids.  Grids only accept a few basic data types.  I suppose a real
gwt-ext developer would just switch to JS code to get around any road
blocks.  That defeats my initial draw to GWT, to avoid JS.

I'll give straight GWT one more try.  If I can just get the panels to
size reasonably...

Re: Single application .. multiple RPC services


Hi Walden,

I'm not sure that I got your idea, but I always had a concern about
that so I'll share it with you:
1. Does the GWT application have just one html page (module-name.html)
that all the content should be rendered there?
What I mean is that Litty wrote if the URL ends with /about then
the AboutService will be called. Well but what if that AboutService
does not extends or consists of any UI element? What is gonna to be
displayed on the browser?

2. What I've received from your idea above is, each service should
have its own (index.html)??!! If that was the case, each time I click
on a menu item then a whole new page is going to be rendered and the
browser will send an HTTP request and page will be rebuilt and
displayed, which is not the case here: http://extjs.com/ Please try to
click any menu item and notice that only a portion of the page is
rendered (the section under the menu) and not the whole page.
Actually, this is exactly what I need to do but I think I was not
clear enough.

3. Suppose that I want to pass parameters in the URL in some
customized format; not using the regular way 
http://domain/service?param1=value1param2=value2.
For example, something like that:  
http://domain/service/param1/value1/param2/value2.
Where should I write my own code that should take care of this
customized URL encoding?? I mean, is there any place in GWT
application where I could capture the URL and manipulate it before
redirect it to some place depending on some parameters passed?? I
guess there is something in .NET called HTTP Handler or Generic
Handler to deal with that. I think this is an issue that the Web
Server should deal with it not the GWT application???!!!

Thank you very much.

 Muhannad,

 There's a problem with your assumptions.  When a user clicks on your
 about menu link, she's not going to get a Panel, she's going to get
 a whole new page fromhttp://domain/about/index.html.  That page can
 be a GWT host file if you like, but this is regular HTML pages, not a
 rich GWT client showing and hiding content based on menu navigation.
 I think you'd better get your head around that first, and then tackle
 the RPC URL binding question next, if it's even an issue at all.

  Hi,

  I want to build a website with (Home, about, products, ...) menu. I
  need to build multiple forms (panels), each panel corresponds to one
  menu item, e.g. aboutPanel for about menu item, productsPanel for
  products...

  Moreover, I would like to implement that panel in terms of RPC
  services; I need to correspond each panel to a single RPC service that
  communicates with the server to get its data, build the whole form,
  and return the result as a panel to be displayed somewhere in the home
  page (for example).

  Of course, GWT allows us to define multiple services and add multiple
  servlet path=/service ... to the module XML file.

  My problem is how to know which service should I instantiate depending
  on the URL mapping, i.e. suppose that the menu is defined as follow:

  div id=menu
      a href=index.htmlHome/a
      a href=/aboutAbout us/a
      a href=/productsProducts/a
      ...
  /div

  So when someone clicks the About us link, the URL would be http://
  domain/about. So I should instantiate the about service and create
  an aboutPanel to display it. The same thing when s/he clicks the
  Products link, then the URL is http://domain/products; and, in this
  case, I should build the product panel...

  So, is there somewhere in GWT application that I could parse the URL
  and depending on the mapping portion of it /about or /products
  could I decide which service to instantiate? Or is there another
  better way to do that?

  Thank you very much in advance.

Sounds like a plan.

 Ray,

I think you actually want to merge the entire 1.6 branch into the 1.6
 clean events branch rather then copying the benchmark and update the
 branch.txt file in clean events with that info. Otherwise, the merge back
 from 1.6 is going to more painful then even today's fire drill was.

   Cheers,

  Emily

 Hey, Kelly.
 The attached is the 1.5 version of the event dispatch benchmark you wrote
 last week, and is intended to be committed to the references directory of
 the 1.5 branch. I plan to svn copy it from there
 to branches/1_6_clean_events/reference and there apply the diff between your
 1.5 and 1.6 versions.

 What do you think?

trunk/user/src/com/google/gwt/core/client/AsyncFragmentLoader.java

Log:
This patch adds a better code-splitting strategy for implementing
GWT.runAsync.  Instead of lumping all non-exclusive code atoms into
the initial download, the initial download only includes the initially
needed code.  Additionally, a custom download is created for each
split point that can be used if that split point is the first one to
be reached.  After the first download, a leftovers fragment is
downloaded in the background.  So, each call to runAsync causes
three fragments to be created: the exclusive fragment as before,
a new custom download, and a leftovers fragment.
