Installer for Deploying GWT Applications

[Simon]

Hi All,

Could someone guide me on how I can make an installer that can be used
to deploy the GWT application I have developed?

I intend to give it out to user, who doesn't have any technical
knowledge on this. The user expects an installer where he can click
all the way through, just like the way one would install Office.

Looking forward to your response!

Re: Hosted mode doesn't work at all on my Vista notebook under Eclipse

Well that was a hellish 3 hours of my life that i'll never get back.
For some reason localhost isn't working on my notebook with jetty.
127.0.0.1 though does work with it.

   The Jetty browser andhostedserver launch but i get an error in the

   Starting Jetty on port 8080  (with two success messages beneath it)

   What is going on?  I don't think that jetty is accepting requests.
   This is on Windows Vista 32 with IE8. Things were flawless on my

   I can create a project and compile it but if i launchhostedmodei

Re: fileupload: ensuring the same file being uploaded

[Vinz369]

Hi Travis,

Thanks for those hints. It looks helpful.
I managed to get something running in the hosted mode, but I still get
a 404 error when I place the code on my server.

Her is my code on the server side:
///
public class UploadFileServlet extends HttpServlet implements Servlet
{

private static final long serialVersionUID = 1L;

public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

resp.setContentType(text/html);

FileItem uploadItem = getFileItem(req);
if(uploadItem == null) {
resp.getWriter().write(NO-SCRIPT-DATA);
return;
}

resp.getWriter().write(new String(uploadItem.get()));
}
private FileItem getFileItem(HttpServletRequest req) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setFileSizeMax(1);
try {
List items = upload.parseRequest(req);
Iterator it = items.iterator();

while(it.hasNext()) {
FileItem item = (FileItem) it.next();
if(!item.isFormField()  
uploadFormElement.equals
(item.getFieldName())) {
return item;
}
}
}
catch(FileUploadException e){
return null;
}

return null;
}
}
///

Do you think that the error is coming from this code of from the
configuration of my server or something else in the rest of my code?
Thanks a lot for your help.

Re: General Question about Coding

[Norman Maurer]

Check your imports... There are to NodeList in GWT:
com.google.gwt.dom.client.NodeList
com.google.gwt.xml.client.NodeList


You should be sure you import com.google.gwt.xml.client.NodeList not
com.google.gwt.dom.client.NodeList. Thats the cause of the error..

2009/8/3 Rahul coolrahul18...@gmail.com:

 Hi,
 I have a general question about coding.
 I am working with XML documents presently and I am not able to
 understand what cast to an object does.

 for example:

 NodeList URLs = (NodeList) root.getChildNodes();

 this gives me an error of
 [ERROR] Uncaught exception escaped
 java.lang.ClassCastException:
 com.google.gwt.xml.client.impl.NodeListImpl cannot be cast to
 com.google.gwt.dom.client.NodeList

 but when i change the code to
 com.google.gwt.xml.client.NodeList URLs = root.getChildNodes();
 this works fine


 also again
 Document xmlDoc = (Document) XMLParser.parse(response.getText());
 this gives me an error
 but
 com.google.gwt.xml.client.Document xmlDoc =   XMLParser.parse
 (response.getText());
 does not

 can someone explain why does this happen??

Re: Using SOYC

Thanks a lot for this post.
It works great.

The GWT team has made a great job on the split code feature and SOYC

 Thanks. Now I was able to create the artifacts files with Compiler

 Later I realized that the stream error was caused by the zero-length
 dependencies0.xml inside dependencies0.xml.gz. So I removed that file
 from the arguments and html files were now created.

 For those, who want a quick start withSOYC, here's what you need to
 do in the webapp's ant build file:

 In the gwtc target add these arguments:
       arg value=-soyc/
       arg value=-extra/
       arg value=extra/

 Create a new target:
   target name=soyc
     java failonerror=true fork=true dir=extra/test1/soycReport
         classname=com.google.gwt.soyc.SoycDashboard
       classpath
             pathelement location=${gwt.sdk}/gwt-soyc-vis.jar/
         path refid=project.class.path/
       /classpath
       jvmarg value=-Xmx1024M/
       arg value=-resources/
       arg value=${gwt.sdk}/gwt-soyc-vis.jar/
       arg value=stories0.xml.gz/
       !-- arg value=dependencies0.xml.gz/ --
       arg value=splitPoints0.xml.gz/
     /java
   /target

 Modify test1 with your module's (rename-to) name.

 Run: ant
 If dependencies0.xml.gz is larger than 10 bytes, uncomment its line in
 the ant script
 Run: antsoyc

Re: fileupload: ensuring the same file being uploaded

Thanks manuel for your reply.
I tried gwtupload. It was not working for me but I suspect it was
because of the configuration.
Since I am very close to my goal using the files I currently have, I
would like to be able to make this very simple example work and
understand how it works before going into more complicated things.
The upload is working fine so far in hosted mode, but still no luck
with the website on the server.
I have another question. At the beginning of this thread you told to
twittwit to use item.getName() to get the name of the file he wanted
to upload. However for me, getName() and getFieldName() both return
the name of the field which is uploadFormElement in my case.

ImageBundle: Why background?

[Benjii]

Hello,

I've been looking at the ImageBundle implementation. Its pretty cool,
except for being unable to resize images. It seems that this is a
limitation of using background image in the ImageBundle
implementation. Is there a reason for doing this? I am no expert, but
it seems like an img and a clip object would let you create a
resizable image from a larger bundle? Or what am I missing?

 So you're saying that a Java app that listens on 127.0.0.1:80 won't
 handle a GWT RPC call? I've never tried it, so I'm just asking...

 GWT uses the browser's XMLHTTPRequest object.

Well, since this is an HTTP request, the listening socket should
respond to such protocol. It doesn't matter whether it's Apache/
Tomcat, IIS, or who knows what listens to the specified port at the
specified local socket, as long as the expected response is compatible
with the XMLHTTPRequest's own handlers. On my system, I have different
(PHP) projects setup on port 80 using different IP addresses
(project1.local=127.0.2.10, project2.local=127.0.2.11, ...) so no need
of any internet connection to develop anything. I'm using Apache/PHP,
but I could have taken the (very) long road and used a custom made
Java application that would have listened to the request, ran the
specified script, and returned the response. It's all a matter of how
custom (home made) you want your application to be. Of course this
is all theory as, IMO, I don't mind using third party software that
works (!) but I've been playing with Netty (http://jboss.org/netty/)
for other networked Java applications and it's a very active and
promising project. With an HTTP protocol support, one could actually
write something with it to handle GWT-RPC requests.

Other than that, having a server bound to local ports also doesn't
require an internet connection, and you could use the embedded Derby
driver as your server side database. Personally, I don't like
SQLlite, so I'd rather use MySQL, but if you want to be all-Java,
Derby is fine, IMHO.

Deferred binding for mobile browser support

[grue]

Hi,

I have to add a mobile-optimized version to an existing gwt
application. After digging through the docs I found out that deferred
binding is the technology of chioce. I believe I understand how it
basically works but how do I use it in that specific use case?
The mobile UI of our application differs a lot from the standard
version so I need seperate stylesheets, and seperate GWT controls (we
use composites a lot). Since the basic layout of our application is
done in the .html file I would also need a separate html file.
Now the question is: how do I do that? Are there any best practices?

I'd really appreciate any hint.

Best regards,
Michael

Selected style do not apply when using widget for treeItem

[shahid]

I have a GWT tree. When I use the tree.addItem(Widget) to add the tree
items as Widgets to the tree, the gwt-treeitem-selected style do not
apply to the tree items any more when items are selected. I have
checked in Firebug.Does any one know how to get round this ?

Strange Problem only with GWT

[Paul van Hoven]

I just uploaded my gwt webapp on my server. The domain is hosted by
another provider. I can forward that domain to my server by making a
so called server redirect and a frame redirect. If i choose server
redirect i have absolutly no problems with my app but if i make a
frame redirect my app does not work correctly it seems as if the rpc
calls a not proceeded. I checked my tomcat log file but i could not
find anything in there. If i make a frame redirect the html looks like
this (extract) (i currently use a dyndns address):

frameset rows=100% frameborder=0 framespacing=0 border=0
frame src=http://flexparken.kicks-ass.net; name=Content
noresizebr

Classical server side generated page seem to have no problem with
that. I only occures with gwt rpc calls. The problem with a server
redirect is that the ip address in the browsers address bar is
replaced by an ip address number.

Has anybody an idea what is happening here and why it does not work?

GWT + light streamer = integration problems

[mnenchev]

Hi, all i need to integrate gwt with lightstreamer. I have some
problems connected with how to call js in gwt. I have been using
native methods before but this time something is going wrong and i
can't understand what.

So here is every thing explained in brief:

Lightstreamer has 2 .js lib files. I include them in my host page and
they are loaded successfully.
I wrote native method that calls some js code that subscribes for ls
feeder:

private static native void init(ListGrid grid, ListGridRecord record,
int recordIndex) /*-{
try {
var page = new PushPage();
page.context.setDomain(localhost);
page.onEngineCreation = function(engine) {
engine.connection.setLSHost(localhost);
engine.connection.setLSPort();
engine.connection.setAdapterName(HELLOWORLD);
engine.changeStatus(STREAMING);
}
page.bind();
page.createEngine(HelloWorldApp, LS/, 
SHARE_SESSION);

var schema = new Array(message,timestamp);
var group = new Array(greetings);

var nvt = new NonVisualTable(group,schema,MERGE);
nvt.setSnapshotRequired(true);
var c = 1;
nvt.onItemUpdate = function(item, itemUpdate, itemName) 
{
if (itemUpdate.isValueChanged(message)) {
var msg = itemUpdate.getNewValue(message);
var ts = itemUpdate.getNewValue(timestamp);
if (c == 1)  {
alert(msg +   + ts);
c+= 1;
}
record.setAttribute(message, msg);
record.setAttribute(timestamp, ts);
grid.refreshRow(recordIndex);
}


}

page.addTable(nvt,hellotable);
} catch(error) {
alert(error);
}
}-*/;'

The same code executed in html page is working, but if i call it from
onModuleLoad()
the alert(error) shows me an error: PushPage is not defined and
PushPage is defined in the external lightstreamer js lib files, which
i included in my host page.

Here is working code in html page:

html

head
  script src=LS/lscommons.js type=text/javascript/script
  script src=LS/lspushpage.js type=text/javascript/script
/head
body

div source=lightstreamer table=hellotable item=greetings
field=messageloading.../div

div source=lightstreamer table=hellotable item=greetings
field=timestamploading.../div


div id=container

Updates:br/

/div

script

var page = new PushPage();
page.context.setDomain(localhost);
page.onEngineCreation = function(engine) {
engine.connection.setLSHost(localhost);
engine.connection.setLSPort();
engine.connection.setAdapterName(HELLOWORLD);
engine.changeStatus(STREAMING);
}
page.bind();
page.createEngine(HelloWorldApp, LS/, 
SHARE_SESSION);



var schema = new Array(message,timestamp);

var group = new Array(greetings);



var nvt = new NonVisualTable(group,schema,MERGE);

nvt.setSnapshotRequired(true);



nvt.onItemUpdate = function(item, itemUpdate, itemName) {
var updateText = updating item  + itemName + . ;



if (itemUpdate.isValueChanged(message)) {

updateText += New value for last_price:  + 
itemUpdate.getNewValue
(message);

}



document.getElementById(container).innerHTML += updateText + 
br/
;

}



page.addTable(nvt,hellotable);


/script



/body

/html

In the gwt application i want to update some grid row and in the html
application i update some div as you can see.

So the main problem is why PushPage is not defined?

Re: gwtSetup is not executed

[Daniel Wellman]

It looks like your method's capitalization is wrong - you want your
method to be called gwtSetUp (with a capital 'u').  If you are using
Java 5 or 6 then using an @Override annotation would have given you a
compiler error, since your gwtSetup method did not override getSetUp.

*.cache.html blocked by firewall - GWT team opinions please?

[Joe Cole]

When debugging a customer who couldn't load our site with an http
connection (worked fine on ssl as it bypassed the firewall) we came
across an issue where if we tried to load the *.cache.html file gwt
was trying to load manually the companies firewall had displayed an
error message. There was no error on the gwt side, so we were unable
to provide feedback to the user.

Is it possible to write something in the nocache.js that checks that
the *.cache.html that is loaded is actually what we expect, and if
not, we can get an error message back to the user in some way?

Currently we use the following method for detecting load errors, but
they aren't being called.  Could it be tied into this in some way?

meta name=gwt:onLoadErrorFn content=loaderror/meta
meta name=gwt:onPropertyErrorFn content=unsupported/meta

script type=text/javascript
!--
// Called when GWT is not supported
function unsupported() {
document.getElementById('loading').className = 
loadError
message-center-screen;

document.getElementById('loading-content').innerHTML = Your
browser is not supported. Please reload with a modern browser such as
a href=\http://www.getfirefox.com\;Firefox/a or Internet Explorer
Version 6 or Above.;
}
function loaderror(){
document.getElementById('loading').className = 
loadError message-
center-screen;

document.getElementById('loading-content').innerHTML = Error:
There was a problem loading the application.;
}
--
/script

E.g. a new meta property could be added that tells us the cache file
is not able to be loaded, with the name of the cache file so we can
show them the error by opening it in a new window so they can see the
error message.

Re: Selected style do not apply when using widget for treeItem

[Chad]

shahid,

When I look at the CSS (via Firebug) on my tree with custom widgets, I
see a hierarchy like this:

gwt-TreeItem
  mm-ResultBar

gwt-TreeItem gwtTreeItem-selected
  mm-ResultBar

In my case, the widget I'm adding to the tree has its own style name
(mm-ResultBar). Make sure you don't set the background of your inner
widget or it will cover up the gwtTreeItem-selected background.

HTH,
Chad

Re: Offline GWT Applications

I do development work all the time using GWT and a local server

over the VPN I work over for the longest time too so I can pretty
definitively say that bog standard GWT RPC does not require any

How exactly do you have your project set up?  Maybe some more

Re: Installer for Deploying GWT Applications

[mikedshaffer]

I can't answer your question directly, but I can offer a few more
questions...you'll get the point.

Where is this application going to be installed?

GWT applications are web browser based applications written in Java
and compiled out to native web language (HTML/CSS/Javascript).  The
application is installed on a webserver.  The client installs the
application just like any other browser based application by entering
the URL into the browsers address line.  So there isn't an install on
the client any more than there is for Amazon or Google...  If you are
looking for something to allow a non technical user to deploy a war
file to a web server, then I guess there's gotta be something for
that.  But why is a non-technical person administering a web server?
Oh well...not going to solve that.  But if you are looking for
something like Office, remember that Office is a traditional heavy
client application that is installed on your local hard drive.  GWT
Applications (just like all web hosted applications) are not installed
on the local machine.

Hopefully this helps, if I'm missing something, please repost with
some additional information and I'm sure you'll get what you need.

 all the way through, just like the way one would install Office.

 Looking forward to your response!

Serializing Exceptions with GWT-RPC

[davis]

Hi, I have tried the following:

public class UserNotFoundException extends Exception implements
Serializable {

// serial uid
private static final long serialVersionUID = 1L;

public UserNotFoundException(String msg) { super(msg); }
}

...and then in my service interface:

@RemoteServiceRelativePath(UserService)
public interface UserService extends RemoteService {

void register(User user) throws UserNotFoundException;

...but when I start up the app in hosted mode, I get:

[ERROR] Type 'com.example.client.exceptions.UserNotFoundException' was
not serializable and has no concrete serializable subtypes

I'm using GWT 1.7.0.  I notice the SerializableException is
deprecated, so I did not use that.  I also tried having the exception
class implement IsSerializable instead of Serializable, but it
produces the same results.

What am I missing?

Re: Hosted Mode CSS Refresh

I'm having the same problem.  My css files are linked from the gwt

I'm going to try by linking them from the host page and see what

To be gwt-serializable, you must have a no-arg constructor

Hibernate GWT

[javier]

Hello folks:

I've posted this question to the Hibernate user's forum, but in the
absence of replies, I am posting it here as well, in the hopes that
some of you may shed some light.  Please accept my apologies if this
is the second time you see this post.

I'm about to engage in an enterprise project whose front-end is to be
built with GWT. I've had some Hibernate experience from past projects
and really like the ORM mechanism used by Hibernate for marshalling/
unmarshalling from a database. Now, as some of you know, domain
entities need to be transferred over the wire for GWT's consumption:
entities that have been instrumented with persistence information will
fail at the client side, as GWT cannot handle these objects.

So I've done some research and I've come across two common solutions
to this problem:

1) Using a framework called Gilead;
2) Replicating the domain model hierarchy with a second class
hierarchy used exclusively for data transfer (aka Data Transfer
Objects representing the persistent domain objects).

None of these solutions are good in my current situation:

1) Gilead intrudes into the design of an application by forcing the
entities to inherit from “LightEntity” and forcing
RemoteServiceServlet descendants to extend “PersistentRemoteService”.
Our design cannot allow this, as both of these type of objects already
inherit from a different hierarchy.
2) Our domain model is composed of 30 classes, some of which have
quite a few getters/setters. Replicating this domain model sounds like
trip to maintenance nightmare street, not to mention the amount of
extra code that we'll need to map things back-and-forth.

So even though I know (from experience) that Hibernate will make me a
lot more productive accessing the database than the alternative (ie
hand-coding with JDBC), all this productivity goes down the drain if I
now have to deal with recreating the objects in order to properly talk
to the client layer.

So now my question is, can I get away with the following:

1) make every single persistent entity to always load everything
eagerly by default (ie lazy=”false”) and make lazy loading the
exception to the rule (ie when fetching lists of things);
2) use a stateless Session-per-request approach, so that every time I
need something from the db a brand new persistence context is
initialized.

I understand that I'll be giving up caching and hence, taking a
performance hit, what I'd like to know is, how bad is this hit? is
this an acceptable compromise in my case? Is this approach still
better than going back to manual JDBC days?

Please advise if this is a horrible approach and if there is something
I should know before I put a rope around my neck.

Thanks in advance for any ideas, comments or suggestions.

How to Perform DoubleClick on FlexTable Cell

[Swathi Kondepati]

Hi All,

Iam working on onCellClicked() method of
FlexTable(com.google.gwt.user.client.ui.FlexTable) cell in GWT.Now my
requirement is i have to change the color of flextable cell into green color
when i perform single click and change the color to yellow when i perform
double click on the cell of an flextable.

To perform doubleclick on flexTable cell i wrote a class
FlextableCatchDoubleClick  but it is accepting single click only.
the code is as follows:

package com.mymdworld.client.utils;


import java.util.Iterator;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.Element;
import com.google.gwt.user.client.Event;
import com.google.gwt.user.client.ui.FlexTable;
import com.google.gwt.user.client.ui.SourcesTableEvents;
import com.google.gwt.user.client.ui.TableListener;
import com.google.gwt.user.client.ui.TableListenerCollection;

public class FlextableCatchDoubleClick extends FlexTable implements
SourcesTableEvents {
private TableListenerCollection tableListeners;

public FlextableCatchDoubleClick(){
super();
this.sinkEvents(Event.ONDBLCLICK | Event.ONCLICK);
}

public void onBrowserEvent(Event event) {
  super.onBrowserEvent(event);
  Element td = getEventTargetCell(event);
  if (td == null) {
  return;
  }
  Element tr = DOM.getParent(td);
  Element body = DOM.getParent(tr);
  int row = DOM.getChildIndex(body, tr);
  int column = DOM.getChildIndex(tr, td);

  int type = DOM.eventGetType(event);
  switch (type) {


 case Event.ONDBLCLICK: {

if (tableListeners  != null) {
 tableListeners.fireCellClicked(this,row,column);

}
break;
 }

case Event.ONCLICK: {
 if (tableListeners != null) {
 tableListeners.fireCellClicked(this,row,column);
}
break;
 }
  }
   }


public void addTableListener(TableListener arg0){
 if (tableListeners == null)
 tableListeners = new TableListenerCollection();
 tableListeners.add(arg0);
}


public void removeTableListener(TableListener arg0)
{
if (tableListeners != null)
tableListeners.remove(arg0);
}



}

In another class iam creating an object of this class and writing
clicklistener for it as:

FlextableCatchDoubleClick table1=new FlextableCatchDoubleClick ();
table1.addTableListener(new TableListener(){

public void onCellClicked(SourcesTableEvents arg0,
int arg1, int arg2) {
-


}


});

How can i differentiate between singleClick and doubleClick of the FlexTable
cell.

Please can anyone help me...
Thanks In Advance

Re: Modelling framework

[Kaspar Fischer]

Nathan,

 The thing is, there IS a framework for what you are trying to do (i.e.
 represent a data structure without being tied to implementation). It's
 called Java. If you're looking for the ability to quickly add fields
 to customer's data structures, that's dependent on low coupling and
 other good programming /techniques/ not a given framework. As far as
 persisting the data goes, you can look at Hibernate or JPA, for which
 there is much information about integrating with GWT.

 I'm sorry if this isn't what you're looking for. Anytime I see someone
 with an class that models classes or types or objects in anyway,
 I start to think, Hey, Java's already done this for me. If you
 really want to go down that route, maybe you should look at
 reflection? Though there's very little support for reflection in GWT.

 Sorry this is getting so long, but I'm just saying that you face a
 trade-off:

 A - have a dynamic/meta-data structure or
 B - have a domain specific data structure

 A - represents huge upfront development and design costs to ensure
 future usability in your domain. Also, runtime efficiency will, of
 necessity, take a hit, as the processor first tries to understand
 the structure, then does the actual processing.
 B - more risk of getting too specific, increasing coupling, and making
 maintainability/rapidly adjusting to customer's ever-changing
 requirements more time consuming. A lot of good OOA/D will go a long
 way to getting you out of these messes though.

Thanks a lot, that answers my question. You put it quite accurately
(It's called Java) and I am glad I have asked. I'll look more into
the supporting frameworks like JPA, Acegi, etc.

how to fill available space with a textarea widget

[Rob]

Hi all,

I'd like to layout a textarea and tell it to fill the remaining
available space (height and width) in it's container. Example HTML is
below.  (Strangely, with the height:100% it looks really messed up and
overflows the div on Safari and Mac Firefox.)

Is there an HTML/CSS solution?  It seems like I need to write some
Javascript to look at the height of the container and set the height
of the textarea.  If so, is that something that's already solved
somewhere in GWT?  I played around some with different panels, but
didn't see anything.

thanks,
Rob

html
head
style
#container {
width: 300px;
height: 400px;
border: 1px solid blue;
}
#text {
height: 100%;
width: 100%;
}
#textdiv {
height: 100%;
}
/style
/head

div id='container'
  div
input type='text' size='30'/
  /div
  div id='textdiv'

CSRF protection for RPC calls - Generate cookie on the client - is it safe?

[jahboite]

Hello GWTers!

Having read the XSRF and GWT section of the page at
http://groups.google.com/group/Google-Web-Toolkit/web/security-for-gwt-applications
I'm trying to implement the suggested protection which involves
sending an extra 'cookie value' param in GWT calls and then comparing
that value with the value of the cookie header.

My question involves the generation of the cookie value and whether it
is safe to do this on the client.  As long as it doesn't impact client
performance, it seems to me that generating a random token, setting
the cookie with that token and sending the same token as a param in
RPC calls would be a neat way to offload CPU cycles to the client.
The server would then only need to compare the cookie header with the
token received in each RPC call and drop the call if the values don't
match (on the assumption that the call hasn't been made by the logged-
in client).

Is that safe?  Is there a way for a forged request to include a
cookie?  If the server merely compares two arbitrary strings, wouldn't
it be easy for a forger to bypass the restrictions relied upon for
this type of protection?

Any insights gratefully received.

Cheers.

Code Igniter Integration

[Marcel Karras]

Hi everyone,

I tried to enhance the my existing Code Igniter (http://
codeigniter.com) based application with the power of optimized
Javascript apps using GWT. The basis is a Java based application using
the GWT library (Eclipse IDE) and the compilation process of this Java
code results in browser optimized Javascript Code… I then can deploy
this Javascript code into CI with some effort in order to get the
widgets I wish.

Now my question: The overall deployment process is quite exhausting
and I would like to Eclipse do all the work where CI is integrated
into a GWT Java Project. (alternatively two projects) GTW advertises
itself as being server-side language independent but if one tries to
implement a server side service you’ll have to use servlets (Java
based) or absolute addresses to the HTTP Remote Interface you want to
send messages to. Concerning the latter issue I have a problem
integrating the CI BASE_URL (the URL prefix of the PHP web
application) into a GWT project without defining the web application
base url twice.

So is there anyone out there who every did this before?

Greetings
- Marcel Karras

Sample Eclipse project/application showing CRUD operations

[nix]

Hello, I am new to GWT.

I have installed eclipse 3.5 and GWT plugin 1.7. I can create/run the

If I am understanding correct, you need to write down Java code and
upon compilation .html/.js files would be created, right?

Can you upload some small sample application, where in CRUD operations
are performed? The downloadable .zip would really help. I tried
samples from showcase, pasted them in helloworld, but ended with
datasource related errors.

Re: Hibernate GWT

You may try Dreamsource ORM. You can find an example including source

Dreamsource ORM is still under development. It will have polymorphic

 Hello folks:

 I've posted this question to the Hibernate user's forum, but in the
 absence of replies, I am posting it here as well, in the hopes that
 some of you may shed some light.  Please accept my apologies if this
 is the second time you see this post.

 I'm about to engage in an enterprise project whose front-end is to be
 built with GWT. I've had some Hibernate experience from past projects
 and really like the ORM mechanism used by Hibernate for marshalling/
 unmarshalling from a database. Now, as some of you know, domain
 entities need to be transferred over the wire for GWT's consumption:
 entities that have been instrumented with persistence information will
 fail at the client side, as GWT cannot handle these objects.

 So I've done some research and I've come across two common solutions
 to this problem:

 1) Using a framework called Gilead;
 2) Replicating the domain model hierarchy with a second class
 hierarchy used exclusively for data transfer (aka Data Transfer
 Objects representing the persistent domain objects).

 None of these solutions are good in my current situation:

 1) Gilead intrudes into the design of an application by forcing the
 entities to inherit from “LightEntity” and forcing
 RemoteServiceServlet descendants to extend “PersistentRemoteService”.
 Our design cannot allow this, as both of these type of objects already
 inherit from a different hierarchy.
 2) Our domain model is composed of 30 classes, some of which have
 quite a few getters/setters. Replicating this domain model sounds like
 trip to maintenance nightmare street, not to mention the amount of
 extra code that we'll need to map things back-and-forth.

 So even though I know (from experience) that Hibernate will make me a
 lot more productive accessing the database than the alternative (ie
 hand-coding with JDBC), all this productivity goes down the drain if I
 now have to deal with recreating the objects in order to properly talk
 to the client layer.

 So now my question is, can I get away with the following:

 1) make every single persistent entity to always load everything
 eagerly by default (ie lazy=”false”) and make lazy loading the
 exception to the rule (ie when fetching lists of things);
 2) use a stateless Session-per-request approach, so that every time I
 need something from the db a brand new persistence context is
 initialized.

 I understand that I'll be giving up caching and hence, taking a
 performance hit, what I'd like to know is, how bad is this hit? is
 this an acceptable compromise in my case? Is this approach still
 better than going back to manual JDBC days?

 Please advise if this is a horrible approach and if there is something
 I should know before I put a rope around my neck.

 Thanks in advance for any ideas, comments or suggestions.

Re: Offline GWT Applications

[Dominic Holt]

Absolutely, I'd be happy to give more details. I'll try and give a
brief overview first, if I'm missing some information you may need
please don't hesitate to ask for it.

Essentially I use NetBeans as my IDE, I also have the GWT4NB plugin.
It's pretty standard as far as RPC calls go, I have a MainEntryPoint
class where all the lovely GUI things happen, and then of course under
the client package I have classes called GWTService and
GWTServiceAsync. Under the server package I have the Implementation of
the service. If I'm online, all the service stuff works just fine. As
soon as I unplug the network cable or set IE to Working Offline I
get the error message: unable to initiate the asynchronous service
invocation -- check the network connection and quite naturally, none
of the RPC stuff works anymore.

When I run the application in the IDE, it deploys on glassfish v3. I
also sometimes package up the build and run it outside of the
development environment on Tomcat 6.x. Either way, the same problem
happens. The glassfish server is on port 8080 and the Tomcat server is
on port 80.

Thanks very much for your help, greatly appreciated.

Re: Google plgin 64 bit support

[Yuri C]

I can't wait for GWT to get 64-bit support.
All of our servers are 64 bit linux machines which allows us to take
advantage of having 4Gb+ of RAM available.

Even my mom says that 32bit is already retro ;)

Installing 32bit JRE worked for me but I only consider it as a
temporary work around.
Otherwise I love GWT!

Re: How to create an UI from Metadata XML file

[Michael W]

Use rpc call.
You have two choices:
1) client makes rpc call and get xml file back, then parse xml in
client side (GWT).
2) client makes rpc call and server parses the xml files, then return
object back to client.

The option 2) gives your chance to cache the xml parsing result it in
server side.

Re: Why is HorizontalSplitPanel a final class?

[Sumit Chandel]

Hi shoe54,
The reason why the HorizontalSplitPanel (and other split panels and widgets)
are declared as final classes is because when these widgets were first
introduced, we wanted to make them very easy to use the right way, and very
hard to use the wrong way. Implementing something like a split panel can be
tricky, and so subclassing such a class and overriding key methods might
have easily led to a broken implementation, and an unhappy developer.

That said, widgets like the split panels seemed to have passed the test of
time, and it seems like allowing them as well as other widgets to be
subclassed should now be part of The Right Way, while continuing to make it
difficult to use or subclass the widgets the wrong way.

Issue #1394 in the Issue Tracker talks about opening up the split panel
class or perhaps replacing it with widgets that provide easier access to
their inner workings. Feel free to start the issue report to get updates as
the team figures out the best way to open it up while leaving it easy to use
correctly.

Issue #1394:
http://code.google.com/p/google-web-toolkit/issues/detail?id=1394

Hope that helps,

Re: Eexception handling in non-hosted mode?

[mars1412]

try/catch over the entire application sounds scary :)

maybe you should use GWT.setUncaughtExceptionHandler() to set your own
exception handler, that would then (maybe) transfer the errors to the
server, if you wish.
in this exception handler you could also use http://code.google.com/p/gwt-log/
logging library to do some logging on the client side (that will show
up e.g. in firebug-console)

Re: Why does not HTMLPanel implement HasHTML interface?

[Sumit Chandel]

Hi Gregory,
The common thing between all the widgets that do implement the HasHTML
interface is that they are all widgets that contain flat HTML as their
innerHTML. This is also true for the HTMLPanel, however, the HTMLPanel also
supports adding widgets to its innerHTML, which could cause problems when
calling getText() or getHTML() and expecting a flat and unchanging HTML
structure to be returned.

Aside from that, it would seem logical for the HTMLPanel to implement the
HasHTML interface, if with the possible caveat mentioned above. Feel free to
create a report for this on the Issue Tracker to get some of the UI team to
consider the change. Before doing that though, could you elaborate a little
more on your use case for having the HTMLPanel implement the HasHTML
interface? There may be other ways to solve the problem depending on what
you're trying to do.

In server side, you need to create and throw

Then you can redirect to the page you want.

OSX Safari Java applet/JNI bug

[Scooter]

I ran across this bug a year ago in Firefox where the String returned
from a Javascript-Applet(Method) call that returns a string isn't a
first class string in GWT. I was testing in Safari OSX and get the
following error message when trying to do a substring on the string
returned from the applet. This was not a problem in FireFox when
testing so I assume the bug was fixed in firefox. To fix it I simply
take the quasi string returned from the Javascript_ applet method
call and do a mystring =  + stringfromapplet. This creates a string
that I can now do substring on without throwing an execption.

Re: 1.7 NoSuchMethodError IncompatibleRemoteServiceException

[Sumit Chandel]

Hi Andrey,
Did you upgrade from 1.5 to 1.7, or from 1.6 to 1.7? I ask because in the
case of the former, there may be remnants in a .gwt-cache folder that
contain old information for the ru.aml.client.database.Row class. If so, try
deleting it and restarting hosted mode again. Also, if you did upgrade from
1.5 to 1.7, make sure that you're using HostedMode and the new war style
directory structure instead of the GWTShell main class used in 1.5 and
prior.

In all cases, make sure that your launch configuration has also been updated
to use the latest GWT JARs.

Hope that helps,
-Sumit Chandel

 Hello!

 I have got a really strange issue.
 When I run my application I get server-side errors like:

 java.lang.NoSuchMethodError: ru.aml.client.database.Row.set(Ljava/lang/
 String;Ljava/lang/String;Ljava/lang/Object;)V
 ...
 com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
 This application is out of date, please click the ref resh button on
 your browser.
 ...

 The method set(String, String, Object) exists of cause and I have been
 using it for a few months on the server-side. Eclipse shows no errors.
 There is also no other Row classes.

 And the really weird thing:
 When I rename class Row for example to Row2 everythning is OK (!)

 I also removed all older gwt-servlet.jar but it doesn't help.

 I have another project which has the similar server-side code and it
 works allright without renaming.

 What can it be?
 Thanks in advance!

oophm with the lastest eclipse plugin on Mac

[Masto]

Hi there,

i'm currently trying to make the oophm works on my Mac using eclipse
3.5 and the latest plugin. I use the revision 5873 of the trunk (ant
clean then ant  my project refers to build/staging/gwt-mac-0.0.0/).

Because i use gwt 2.0, a checkbox appears under Run Configuration 
GWT Tab  just under the URL. So i checked it.

The Swing window shows up but with a beachball running, so i can not
click on it.

Did someone face a similar issue? How did you work it around ?

Thanks,

Re: Configuring GWT to run in hosted mode against a non-Java server

[Sumit Chandel]

Hi Damon,
Have you checked out the FAQ link below on using your own server instead of
GWT's built-in Jetty instance?

How do I use my own server in hosted mode FAQ:
http://code.google.com/webtoolkit/doc/1.6/FAQ_DebuggingAndCompiling.html#How_do_I_use_my_own_server_in_hosted_mode_instead_of_GWT's

http://code.google.com/webtoolkit/doc/1.6/FAQ_DebuggingAndCompiling.html#How_do_I_use_my_own_server_in_hosted_mode_instead_of_GWT'sRegarding
using JUnit with your RESTful RPC calls, could you elaborate a little more
on what you'd like to do from within a JUnit test case that would require
making RESTful RPC calls? Ideally, a unit test only tests various cases on a
specific unit of functionality, and so a unit test over a RESTful RPC call
would probably be completely separate from a unit test over your GWT code.

Hope that helps,
-Sumit Chandel

 internal tomcat instance on port 0 and talk to that server rather than
 my non-Java web server. I've checked docs and also GWT in Action, but
 don't see much on this topic.

Inlining nocache.js

[George Georgovassilis]

So, while trying to squeeze out the latest tiny bit of speed for my
application I ended up with this setup:

index.html ( = module page) contains inlined css and the nocache.js.
The index.html is non-cacheable, but is guarded with an E-Tag, which
doesn't do anything to first time users, but recurring users will see
a 304 (not modified) and the application will load instantly. I
inlined the CSS so that no further HTTP request is neccessary, the
same rationale goes for the inlined nocache.js

So the only HTTP requests are:
1. load the index.html
2. load a sprite image
3. load the browser dependent *.cache.js

The problem here is that since I inlined nocache.js, now index.html
has to reside in the same location with *.cache.js, which is horrible
to configure for caching since I'm not using Apache but just Tomcat.

Using a base href= to bend the base location seems to work only on
Firefox, IE can't find its RPC services and Safari won't load at all.

Any ideas?

Re: Offline GWT Applications

[jhulford]

Is the server on the same machine as as your development environment?
ie. is this all done locally via RPC to the loopback or localhost
address?

On Aug 4, 12:29 pm, Dominic Holt domh...@gmail.com wrote:
 Absolutely, I'd be happy to give more details. I'll try and give a
 brief overview first, if I'm missing some information you may need
 please don't hesitate to ask for it.

 Essentially I use NetBeans as my IDE, I also have the GWT4NB plugin.
 It's pretty standard as far as RPC calls go, I have a MainEntryPoint
 class where all the lovely GUI things happen, and then of course under
 the client package I have classes called GWTService and
 GWTServiceAsync. Under the server package I have the Implementation of
 the service. If I'm online, all the service stuff works just fine. As
 soon as I unplug the network cable or set IE to Working Offline I
 get the error message: unable to initiate the asynchronous service
 invocation -- check the network connection and quite naturally, none
 of the RPC stuff works anymore.

 When I run the application in the IDE, it deploys on glassfish v3. I
 also sometimes package up the build and run it outside of the
 development environment on Tomcat 6.x. Either way, the same problem
 happens. The glassfish server is on port 8080 and the Tomcat server is
 on port 80.

 Thanks very much for your help, greatly appreciated.

Re: JNSI Problem Challenge

The only version i succeed to make working is

  public static native void exportStaticMethod() /*-{
$wnd.myJavaStaticMethod =
   @com.st.jsni.client.Jsni::sum(II)(34,35);
}-*/;


But of course this give 69 and does not take in count the parameters
of alert(myJavaStaticMethod(1,2));  that should give 3.

Hope this help.

Re: Offline GWT Applications

[Dominic Holt]

Yes, everything is on the same machine. The address that displays in
the browser when the application is running is http://localhost:8080/AppName/

  Absolutely, I'd be happy to give more details. I'll try and give a
  brief overview first, if I'm missing some information you may need
  please don't hesitate to ask for it.

  Essentially I use NetBeans as my IDE, I also have the GWT4NB plugin.
  It's pretty standard as far as RPC calls go, I have a MainEntryPoint
  class where all the lovely GUI things happen, and then of course under
  the client package I have classes called GWTService and
  GWTServiceAsync. Under the server package I have the Implementation of
  the service. If I'm online, all the service stuff works just fine. As
  soon as I unplug the network cable or set IE to Working Offline I
  get the error message: unable to initiate the asynchronous service
  invocation -- check the network connection and quite naturally, none
  of the RPC stuff works anymore.

  When I run the application in the IDE, it deploys on glassfish v3. I
  also sometimes package up the build and run it outside of the
  development environment on Tomcat 6.x. Either way, the same problem
  happens. The glassfish server is on port 8080 and the Tomcat server is
  on port 80.

  Thanks very much for your help, greatly appreciated.

[ERROR] Uncaught exception escaped java.lang.NullPointerException: null

[Rahul]

Hi,
I am trying to parse an xml file and then for each xml entry, im
parsing another xml file into for loop and then creating vertical
panels and adding labels to the content of the second xml file.

This is my code:

try
{
Request request = builder.sendRequest(null, new 
RequestCallback()
{

@Override
public void onError(Request request, Throwable 
exception) {}
public int j =0;
@Override
public void onResponseReceived(Request request,
Response response)
{

Document xmlDoc =   
XMLParser.parse(response.getText());
XMLParser.removeWhitespace(xmlDoc);
Element root =  
xmlDoc.getDocumentElement();
NodeList URLs = root.getChildNodes();

for ( j = 0; j  2; j++)
{
v1[j] = new VerticalPanel();
String str = 
URLs.item(j).getAttributes().toString();
System.out.println(str);
tab.add(v1[j],str.substring(13,16));

RequestBuilder builder1 = new RequestBuilder
(RequestBuilder.GET,str.substring(13,16)+.mdl);
try
{
Request request1 = builder1.sendRequest(null, new 
RequestCallback()
{

public void onError(Request request1, Throwable 
exception) {
}

@Override
public void onResponseReceived(Request request1,
Response response1)
{
Document xmlDoc1 = 
XMLParser.parse(response1.getText());
XMLParser.removeWhitespace(xmlDoc1);
Element root1 = 
xmlDoc1.getDocumentElement();
NodeList URLs1 = root1.getChildNodes();

for (int i =0; i URLs1.getLength();i++)
{
String str1 = 
URLs1.item(i).getAttributes().toString();
System.out.println(str1);
v1[j].add(new Label (hi));   
// this line creates the error
}


}

});
}
catch(RequestException e){ }

//end of for loop
}



}

});
}
catch(RequestException e) {}

I have commented the line by which i get the error, why is that?
i could not see whts wrong in my code
please help

Re: gwtSetup is not executed

Thanks Daniel for pointing out.
It was stupid careless simple mistake. Feel shame to bother everyone.
Sorry.

 It looks like your method's capitalization is wrong - you want your

  I feel strange that I could not to find any discussion about such

  Here's the simple test case as an example:
  package com.appspot.inetools.newsfetcher.client;

  I launch that test by ValidaterExecuterTest-hosted.launch file on
  Eclipse (Galileo or Ganymede).
  Expected it to pass, but it fails.

My guess is that the entire environment has not been created, hence the
object expected error. What I'm saying is that the GWT-generated code
that loads the $wnd.myJavaStaticMethod runs after the scripts in the
body tag.
You can try something like if (window.sum) sum(3,3); to prove this.

You won't usually use GWT in the style of putting scripts in the body
tag. You'll usually load the scripts via the head tag. Even when
retrofitting existing systems, this is the common technique.

Google plugin demands an -AsyncAsync version of a service interface [Solved]

[Tim McCormack]

When I updated Google Plugin for Eclipse from version 1.0.1 to 1.1.0,
my GWT project started throwing errors. I had a DataService class and
a DataServiceAsync class that were working fine, but GWT was claiming
that DataServiceAsync had an error and needed a DataServiceAsyncAsync.

In my case, the solution lay in editing the interface declaration.
Here's how DataServiceAsync used to start:

@RemoteServiceRelativePath(data)
public interface DataServiceAsync extends RemoteService {

I changed it to this:

public interface DataServiceAsync {

That fixed it! I suppose that this situation arose when I copied
DataService.java to DataServiceAsync.java and then fixed up the method
signatures and class name, but neglected to remove the annotation and
inheritence.

Apparently the older version of the plugin did not mind, but the newer
one does.

Re: Creating and Importing GWT Independent Modules

i've done everything, but now when i compile the code i get import

if i remove or change the gwt.xml with a different name it complains that it

 Hi Lucas,
 You can follow the steps below to package an existing module, say module A
 defined in project A, that you want to reuse in another project, say project
 B that defines module B which itself defines an entrypoint class.

 1) Create / move all the GWT code that you want to reuse in project A.

 2) Create / update the module XML file for module A in the normal way,
 except you no longer need to define an entry point class.

 3) Create a JAR for project A (project-a.jar), which should include 1) GWT
 source code that you want to reuse from the project, 2) The module XML file,
 3) Any other public resources referenced by the module XML file,  4) The
 binary .class files for any server-side code that you want to reuse

 4) Add the project-a.jar file to the project B classpath, as well as any
 other launch configurations related to project B (typically hosted mode and
 compile configurations).

 5) Reference the module A xml file from the module B xml file (e.g.
 inherits name=com.google.projectA.ModuleA /). Note that since the module
 A xml file should already include the inherits
 name=com.google.gwt.user.User / inherits tag, you shouldn't need to add
 that reference again to the module B xml file.

 You should be ready to go. Give those instructions a try and let us know if
 you managed to package and reuse your module.

 Hope that helps,

java.io.NotSerializableException for gwt portlets - wps 6.1

[kss]

We are getting  java.io.NotSerializableException in one of our gwt jsr
286 api portlets in WebSphere Portal 6.1. This exception has started
to surface in the logs since we enabled session replication on our
WebSphere Portal server. The object which its complaining about has
isSerializable interface implemented. When we dont have session
replication enabled; the issue dosent occur.

Has anyone seen this exception in websphere environment for gwt
portlets or have any ideas ?

Will I have memory leaks if a Widget is removed from Panel without call to HandlerRegistration#removeHandler()

[Justas]

There is an application in which a Panel instance is *Handler for
widgets, which are added dynamically depending on the result returned
by async call. Instances of HandlerRegistration are not maintained by
the application (i.e. values returned by #add*Handler() are not stored
anywhere).

Now lets suppose that one of these widgets is removed from the panel
without calling respective HandlerRegistration#removeHandler(). Will I
have unnecessary references to the panel related to removed widget? Is
it possible that this panel (as a Handler) will be invoked to handle
an event (either native or logical) having removed widget as a source
(either before or after garbage collection)?

GWT 1.7, no JSNI used.

Re: Modelling framework

[ckendrick]

With SmartGWT you can represent a data structure as a DataSource.  A
DataSource can be tied to any kind of data provider - not just
different JPA implementers but also WSDL web services, REST services,
non-JPA persistence systems like Ibatis, etc.  The persistence engine
is pluggable, so you can swap strategies, even swap platforms (eg Java
to PHP backend) without changing the UI.

With SmartGWT Pro you can generate SQL tables or Hibernate entities
from a DataSource, or vice versa, that is, generate a DataSource from
existing SQL tables or Hibernate entities.  Then you can just drag the
DataSource onto a grid component and you've got the ability to do CRUD
operations without writing any code, and you can add business logic
from there.

Probably the best single overview is here:

Re: *.cache.html blocked by firewall - GWT team opinions please?

[Joe Cole]

I have been able to simulate the problem by causing a 404 when the
*.cache.html is requested.

Stepping through firebug, this is the relevant code in
the .nocache.js:

22 function maybeStartModule(){
23 if (scriptsDone  loadDone) {

scriptsDone is never true because the script is no longer available,
which is happening when the cache.html gets blocked by a firewall.
Therefore our application stays in a perpetual loading application
page which isn't a good look.

Is there a way to test whether the cache.html file has the correct
content, assuming there is a way to wait for it to load completely?

Joe

 When debugging a customer who couldn't load our site with an http
 connection (worked fine on ssl as it bypassed the firewall) we came
 across an issue where if we tried to load the *.cache.html file gwt
 was trying to load manually the companies firewall had displayed an
 error message. There was no error on the gwt side, so we were unable
 to provide feedback to the user.

 Is it possible to write something in the nocache.js that checks that
 the *.cache.html that is loaded is actually what we expect, and if
 not, we can get an error message back to the user in some way?

 Currently we use the following method for detecting load errors, but
 they aren't being called.  Could it be tied into this in some way?

 meta name=gwt:onLoadErrorFn content=loaderror/meta
 meta name=gwt:onPropertyErrorFn content=unsupported/meta

 script type=text/javascript
                 !--
                         // Called when GWT is not supported

 message-center-screen;
                                 
 document.getElementById('loading-content').innerHTML = Your
 browser is not supported. Please reload with a modern browser such as
 a href=\http://www.getfirefox.com\;Firefox/a or Internet Explorer
 Version 6 or Above.;

 E.g. a new meta property could be added that tells us the cache file
 is not able to be loaded, with the name of the cache file so we can
 show them the error by opening it in a new window so they can see the
 error message.

Re: Modelling framework

It apparently can be tied to a backend datasource, although all of these
examples have
setClientOnly(true)

There are no examples that I know of actually showing a connection, for
example with a sample mysql database or really anything else.  Please
correct me if I'm wrong.

Re: making gwt rpc call from ordinary java

[rjcarr]

I'm reasonably sure this is what the JSON packages are for.  You'll
want to pass messages around using JSON, not the custom serialization
done by GWT, as that would make what you're trying to do greatly more
complicated.

Re: Modelling framework

Hi John,

For live connections to SQL, Hibernate and other data providers see
the SmartGWT Pro/EE showcase:

As well as Sanjiv's blog on SmartGWT Pro/EE, which is the link I meant

Note that the SmartGWT non-Pro/EE showcase shows clientOnly

Every interaction you see in the SmartGWT showcase with a clientOnly

Re: same problem

[Sumit Chandel]

Hi Sven,
Are you using the GWT Eclipse plugin for your project? If so, did you create
the launch configuration you're using to start hosted mode with the plugin
wizard?

One thing to try to solve this issue is to ensure that the code you're
trying to Compile/Browse is indeed the latest running in hosted mode.
Typically, you can make sure that the latest code is picked up by hitting
Refresh on the hosted mode browser. My guess is that you've already tried
this, and probably even restarted hosted mode to make sure the new code
changes were picked up. I just wanted to mention it in case.

Hope that helps,
-Sumit Chandel

Re: Google plugin demands an -AsyncAsync version of a service interface [Solved]

[Miguel Méndez]

Version 1.1.0 checks GWT RPC interfaces.  Any interface that extends the
RemoteService marker interface is considered to be a sync interface.  Once
that happens it looks for an async interface.

On Tue, Aug 4, 2009 at 6:09 PM, Tim McCormack ti...@ccs.neu.edu wrote:


 When I updated Google Plugin for Eclipse from version 1.0.1 to 1.1.0,
 my GWT project started throwing errors. I had a DataService class and
 a DataServiceAsync class that were working fine, but GWT was claiming
 that DataServiceAsync had an error and needed a DataServiceAsyncAsync.

 In my case, the solution lay in editing the interface declaration.
 Here's how DataServiceAsync used to start:

 @RemoteServiceRelativePath(data)
 public interface DataServiceAsync extends RemoteService {

 I changed it to this:

 public interface DataServiceAsync {

 That fixed it! I suppose that this situation arose when I copied
 DataService.java to DataServiceAsync.java and then fixed up the method
 signatures and class name, but neglected to remove the annotation and
 inheritence.

 Apparently the older version of the plugin did not mind, but the newer
 one does.

IE and Buttons without a form

[John Huss]

I have a few TextBoxes and some Buttons that are NOT in a form or a
FormPanel.  I have a ClickHandler for the buttons that reads the
fields and updates the UI.  Additionally I added KeyPressHandlers to
the TextBoxes to catch ENTER and then fire the button's action.

This works fine in all browsers except IE.  In IE, one of the Button
wrongly gets hightlighted, presumably because it is the default
button, and when I press ENTER the key is not captured by the TextBox
but instead something else happens - if I remember correctly it
reloads the page.  Anyway, my handlers are never executed.

So is there any way to:
1) Disable the highlighting of the default button
2) Prevent the browser from stealing the ENTER key from the TextBoxes

Thanks,
John

Re: Modelling framework

[ckendrick]

We do give you the ability get in and override any part of the
generated SQL as a Velocity template.  Simple example:

http://www.smartclient.com/smartgwtee/showcase/#large_valuemap_sql

Tour de force (dynamic reporting with filter, sort and data paging, no
server code required):

   http://www.smartclient.com/smartgwtee/showcase/#sql_dynamic_reporting

I think that would cover you for lot of use cases.  If there's
something more we should be doing here I'd love to know.

Note that we also have upcoming support for XML DB (Berkeley OSS and
Oracle flavors).  It's just another type of DataSource, which
generates XQuery instead of SQL.

rpc serialization problem

I have a simple one-to-many betwen two entities.  The parent entity
uses List to contain the child entities.  I am able to persist these
entities in the datastore without problems.

However, when reading a root entity at the server, I get:

rpc.SerializationException: Type 'org.datanucleus.sco.backed.List' was
not included in the set of types  which can be serialized...

The entities are successfully read from the datastore, but something
in Datanucleus doesn't build the List correctly.

Re: oophm with the lastest eclipse plugin on Mac

[brett.wooldridge]

Yes, I was having this problem and posted the answer to my own
question in the above mentioned link:

To answer my own question, and for other users having the same issue,
this worked: I created a standard Java Application launch
configuration, using com.google.gwt.dev.HostedMode as the Main class,
and the above recommended classpath. You'll have to get the command
arguments right, but you're bright enough to figure that out. Having
done that, it would appear to work.

It was never clear to me when reading the instructions before (maybe I
should have read more carefully) that a Web Application launch
configuration could no longer be used. A Java Application launch
configuration is required. That's the magic sauce.

Note, OOPHM will not automatically launch your browser on the Mac.
You will instead see an error in the OOPHM console about firefox.
Ignore it.  Copy the URL it tried to launch firefox with and past it
into Safari (assuming you have installed the OOPHM .dmg file to get
the browser plugin).

See my other comments on the above referenced page about other issues
you may experience.  But basically it works.

  The Swing window shows up but with a beachball running, so i can not
  click on it.

  Did someone face a similar issue? How did you work it around ?

  Thanks,

  Thomas

Cookies and client state. Suggestions?

[brett.wooldridge]

I have a question about cookies and maintaining client-side state, and
looking for suggestions about how to solve (what I perceive to be) an
issue (for us).

We allow the user to create a sticky login.  You know, the one where
they tick the checkbox that says something like Stay logged in?
This of course creates a persistent authentication token (cookie) on
the client.  Really we only need this cookie on the first hit from
the client -- we re-authenticate then send back (via RPC) a session
identifier that is used in all further conversations with the server.

What we would like to avoid, but seems unavoidable (hence this post),
is having the cookie sent with every request to the site.  Because the
entire site, from the front page all the way back is one entire GWT
application, the path (in cookie terms) is always the root of our
server.  Therefore, the cookie gets sent with every RPC to every
service.

We would like to stuff additional persistent information down to the
client for survivability across visits, such as user preferences, but
we don't want this stuff blasted back to us with every request.  For
the purpose of envisioning our traffic patterns, imagine our site is
an online game (it's not, but...) with a single client making one call
every second or three and 10k+ simultaneous users.  Right now the
typical payload is only two or three dozen bytes, but the size of
the cookie even though small is actually larger.  We could cut our
traffic in half without the cookie being sent back on every request.

Is there an effective way to break up an single application across a
URL space?  Maybe via multiple modules?  For example, can we serve the
'login' module .js files from domain/login and the 'settings'
module .js files from domainsettings?  If so, does that mean that
from GWT I can access cookies in the path '/login'?  My concern is
that because the page was served from domain/, even though the
script was served from domain/login that those cookies will not be
accessible.  As it is, if the server sends back a cookie with a path /
login, they are not accessible to the client.  I was surprised,
though maybe shouldn't be, as I expected JavaScript served by a
certain domain to be able to access ALL cookies in that domain,
regardless of path.  That seems not to be the case.

Thoughts and suggestions welcome?

[gwt-contrib] Re: Async interface black magic

[John Patterson]

 I bet you were into the lovely EJB artifacts too?  Ha ha this is strangely
 reminiscent.


 No, I wasn't.  Really, I don't see the correlation.


Boiler plate, _almost_ duplicate interfaces anyone?  Business methods
defined in the remote interface must be duplicated in the bean class


 My feeling as a GWT developer is that overall GWT has been moving, from 1.6
 thru 2.0 trunk, to a position of being less confusing and more deterministic
 and predictable.  I like this.


Very true.  If I had time I would love to hack the gwt compiler to see what
kind of problems might occur if it generated continuation style js.


 I think, boiled down, my feeling is that the impedance mismatch between
 XmlHttpRequest and RPC continuations is just too steep to ever really
 abstract away successfully, so I worry that any effort in that direction
 would be bootless.  Mind, I would probably have said that several years ago
 about Java-to-JS compilation in general, so if anyone can prove my belief
 wrong, it's this gang here.


Yes I agree that the guys behind GWT change the way you think about client
side web dev which makes anything seem possible.  Maybe even the impossible.

Cheers,

John
