How to send data to client in a regular interval?
Hi all, Is it possible to send the updated data from DB to the client in a periodic interval and without any request or call from the client? I want to know about this because, I have a grid with set of rows and columns fetched from DB, after populating the grid, if there is any further updates in DB to the data displayed, that should get reflected in my Grid. so I thought of placing a code inside the timer (in Server) and get the latest data and pass that on to the client. In this case, client should be always ready to get any data comes from the server. Can anyone help me in this regards?

Re: debugging doesn't work with -noserver
Yes, I can debug normally without -no server..

Re: How to send data to client in a regular interval?
Hi, Thanks for the reply. OK. Now I can confirm my predictions was right. I already checked that from my end, but I want to confirm is there any other ways of doing it. So at the end, its not possible..hmm. So now what I am trying to do is, Storing the keycolumns of the rows initially sent to client in an array, and I am initiating the request from the client now, and fetching the same values from the DB and comapring with the existing values. If there is a difference then sending that to client, else leave that row as such.. Tell me if anyother way of doing it, or is there any disadvantages of doing it?

Re: GWT RPC Encryption

This is just one step more protection, but should be effective in prevent normal users from forging the request just by using plugin in firefox. GWT has already obfuscated the javascript source code when compiling, this is great. I was thinking maybe we can take one step further to encrypt the data (only for sensitive information rpc.)

Re: Returning to Java after a long lapse and starting with GWT. Any recommended books that cover both?
Hi Agree with Lars here the documentation on GWT website is excellent and If you use eclipse plugin you should be up and running. I have read a number of the GWT books and think GWT in Practice is great book for showing the bigger picture for GWT demonstrating other technologies it integrates with. Other than that Google Web Toolkit Applications was another good read.

Re: Accessing external widgets from my Handler
Trevor, Somehow you need to pass references. You could do that in your own EventHandler or Callback implementation. In my app I have a Callback implementation that takes a reference to a panel, I suppose the equivalent of your Page object, in the contructor. The Callback keeps the reference in an instance variable, parses the response from the server and then sends that response to some method in the panel. The panel itself has the necessary references to its children., like your button and table. I think you could implement an EventHandler in a similar way. Of course you have to evaluate if all that referencing is worth the trouble. If you want to do something simple, perhaps keeping all the code in the Page object is not such a bad idea after all.

Re: How to use GWT to build a bottom bar with pop up menu
All you really need is a panel, any basic type would do. And
dynamically add contacts to this pannel as hyper text or buttons.
Not sure you really need a stack panel for this.
Example:
private VerticalPanel myVerticalPanel = new VerticalPanel();
protected ArrayListButton myButtons = new ArrayListButton();
ClickHandler myButtonHandler = new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
if (button != null button instanceof Button) {
String mytitle = button.getTitle();
// Use the title that has the name in it to do what you
need to do
} else {
//TODO: Some error
}
}
};
// Load the buttons into the panel
public void load();
myVerticalPanel.clear();
for (ButtonBase button : myButtons) {
myVerticalPanel.add(button);
}
}
// Add a button to the list
public void add(String name) {
Button myButton = new Button(name, myButtonHandler);
myButton.setTitle(name);
myButtons.add(myButton);
load();
}
The above simple example is an example. You can add and remove items
from the veritical panel, thus you would not have
to reload the complete panel everytime.
Hope this helps
private VerticalPanel myVerticalPanel = new VerticalPanel();

to a web site, some thing similar to what FB does. But I don't need it
to be much advanced like that. Only displaying a list of contacts as a

I would be really thankful, if any of you kindly point me some

Alex, You don't need to click for the list to appear. Just type part of the search text in the box, the list of corresponding items should appear (if the limit is respected, I think default value is 20). You scroll to or click one of those items to select. Your SelectionHandler then processes the selected item.

button that the user hits and then it does the normal mailto: href.
What is the code to accompilish this?
Thanks and sorry for such a simple question.

Re: Is it possible to compile a no javascript version using gwt toolkit
You have to remember that GWT is not a single solution for creating a web site. It is (or rather can be) just one part of the whole system. GWT primarily performs DOM modification and XMLHTTP requests (with lots of other fancyness that makes those tasks much easier for the developer). These things tend to not be spiderable or convertable to raw HTML. The host pages that the GWT modules inhabit are, on the other hand, very spider friendly, and can be designed in such a way that they display content that you would like to have indexed. These host pages don't necessarily need to be static html but could be JSP or PHP or any other server side technology that provides HTML to the browser. There are quite a few long discussions on this list about SEO and how GWT fits into the big picture as it were. -jason On May 30, 2009, at 5:54 AM, Saurabh Agarwal wrote: Thanks Ian for your input.

Re: GWT VS GWT-EXT
UHM ... that question is a bit confused. GWT is the Toolkit in which GWT-EXT exists. without GWT there is not GWT-EXT. the EXT variants (GWT libraries based on EXT) seem to be rather popular, but also seem to have more than their fair share of detractors. You can search the list for information on the Pros and Cons of using various external Libraries with GWT. That said, I tend to try to stick to straight GWT (and occasionally GWT-Incubator) for my projects. It reduces number of externally induced headaches. But, your situation may be different. Best to create a sample app using the proposed libraries to determine if it is fit for your project. -jason On May 31, 2009, at 11:11 AM, Fitrah Elly Firdaus wrote: Dear All, I'm New Member, I want Ask about this, what's differences GWT and GWT-EXT?

Re: Getting an error saying Did you forget to inherit
Generally, you should not have any dependencies from code in src on code in test. I believe that the problem here is that the Utils class is in the test folder, but the source path for your module is client. You can add test to your module's source path, but I'd recommend that you move the Utils class under your src folder, and then create a module for your tests that inherits from your Start module.

Re: dependencies on GWT project in eclipse gives exception..whats problem?
There are a couple things to be aware of here.
There are some issues with having a WebApp project depend on a Java project.
The crux of the problem is that the artifacts from the Java project are not
automatically copied over to the WebApp's war directory. See the following
thread for more information:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/951499c5773693c9
Another problem may be that you're explicitly including Xerces as part of
your WebApp project libraries (or maybe one of the libraries that you're
using bundles Xerces). There is no need to deploy your own Xerces library;
one is already available to the platform, and adding your own can cause
ClassLoading issues.

Getting HttpSession from JAX-WS Soap message handler class.
Hello, i wrote up GWT application who acts as proxy between client( browser in that case) and web services. Communication with web services is used using JAX-WS libraries. Here need to save each user id to maintain session with web services application service. That id i save reading and writing soap messages header, i use SOAPHandler class for that. From here all is ok. But then i need to save that id for each browser window who connects my servlet using rpc call. And here is the problem: i can get HttpSession object only from class that extends RemoteServiceServlet, like this getThreadLocalRequest().getSession(). But cant get that object from soap handler class, or pass it as parameter. How i can get HttpSession in any other way? Or there is any other way for storing things in servlet? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

JAX-WS Web Service and GWT
Hi there, I am developing a user front end application using GWT where I want to connect it to an already existing Web Service. What I have gathered from the GWT documentation is that I require a server instance using GWT-RPC which sits between the User Client Brower front end and the existing Web Service, i.e. Users Browser GWT Client (1) | V GWT-RPC Server (2) | V (JAX-WS) Web Service (wsdl) (existing) I am not interested in developing the UI on the clients side yet but what I have done is I have created the GWT-RPC above and have used the WSDL of the Web Services and JAX-WS's 'wsimport' to create a client proxy. The problem that I am getting is that I get the following errors appear in the Problems section of Eclipse 3.4 J2EE javax.jws.soap.SOAPBinding is not supported by Google App Engine's Java runtime environment javax.jws.WebResult is not supported by Google App Engine's Java runtime environment javax.jws.WebMethod is not supported by Google App Engine's Java runtime environment javax.jws.WebParam is not supported by Google App Engine's Java runtime environment It a bit obvious from the errors that the Google App Engine doesnt support the JAX-WS library Does anyone know how I can get around this?, or even is there another Web Service tool that the Google App Engine does support in being able to connect to Web Services?

I've searched the web for days on this and have found nothing. My issue is that I have a TabPanel with a number of tabs on it. Each tab has a similar sort of layout with a text box, a button, and a flextable. The flextable initially starts out invisible (.setVisible(false)). When the user clicks on the button a simple database lookup is performed and the flextable is populated and made visible. The problem is, the TabPanel does not expand to accomodate it. I only see the first couple of rows of the tab panel. There is no scrollbar, but I can scroll the window by selecting the table and dragging the mouse inside of it. Changing tabs and changing back causes the window to resize. I have not been able to find a redraw method or any other way to force the widget to update to accommodate the larger child. I've tried setting it to invisible and back to visible again to cause it to resize, but nothing I can do from code seems to have any effect.

Re: GWT server side access to web service from another server
Hi there,
Are you using the Google App Engine by any chance? The reason I ask is
that I am trying to develop a front-end UI using GWT and have been
able to developed a proxy server using GWT-RPC with intentions to
connect to an existing Web Service (very similar to your architecture
you have described). I have used 'wsimport' to can generate a jax-ws
proxy using the WSDL all fine but I am getting errors as below:
javax.jms.soap.SOAPBinding is not supported by Google App Engines JVM
environment,
javax.jms.WebParam is not supported by Google App Engines JVM
environment,
javax.jms.WebMethod is not supported by Google App Engines JVM
environment, and
javax.jms.WebResult is not supported by Google App Engines JVM
environment
Does anyone have an idea of how I could go about fixing this?

Re: GWT and backend technology
Can you provide a bit more information on how you're launching the debug session? Is it a remote-debugging session, can you provide some more information about the listening process (the one being debugged) and the one connecting to the listener (which would be in your IDE)? I'm specifically interested in how you're launching both processes. If this is an in-IDE debug session, and you're using Eclipse, are you making sure that your launching the application using a Debug launch configuration, as opposed to a Run launch configuration?

Re: DatePicker and setting the time
Thad, I would suggest adding a feature request to the GWT issue tracker. That's a good way to make it known that you're interested in seeing such a Widget in the core library. If you liked the Incubator's DateTimePicker, I would mention that in the report and suggest getting the ball rolling to have it promoted. Also, if you could post in this thread with a link to the new issue then others can star the issue to show their interest. - Isaac On Sun, May 31, 2009 at 3:23 PM, Thad thad.humphr...@gmail.com wrote: I understand that DatePicker will allow setting the hour, minute, etc. if that is set in the Date. What I'm looking for is a UI like the incubator's now deprecated DateTimePicker class had. Otherwise users are left having to enter a time format correctly in text boxes. To my mind, DateTimePicker should not be deprecated because the DateTime widget does not have the full functionality of the former. As DateTime has CalenderModel/View, I think there should be a TimeModel/View and the option to display a TimePicker in the DatePicker. On May 29, 1:42 pm, Kwame iweg...@gmail.com wrote: Hi Thad, Have you tried datePicker.setValue(new Date(year, month, date)) or to format the output, maybe something like: String dateString = DateTimeFormat.getMediumDateFormat().format (datePicker.getValue()); I have a similar problem.

Hi Neo, Is the class from which that stack trace stems declared without any access modifiers? I recall a previous thread which described a similar issue. The problem there was that there was a class defined with no access modifier that lived in a different package than the module entry point class. Adding public to the class to make it visible to the GWT compiler fixed the issue.

Spring Security login forwarding to blank page issue
I've done a bit of searching around the forums but haven't seen this issue crop up (though there are plenty of blank page issues from what I've seen). I'm having an intermittent issue where when I login to my application (I use Spring Security as my security framework), it forwards to my app's HTML page (my application's entry point). Sometimes it will then load and show the application, other times it shows just a blank page. If I refresh the blank page, my application comes up without fail. This would lend me to believe that this is a caching issue. Has anyone else experienced this and have any advice on solving it?

GWT Application aspects
¡Hello everyone! I am trying to set up an initial skeleton for an application. In order to achieve this i considered every aspect (not EVERY ONE of them, of course) of the application i'd like to handle and reached the following decision: Views, presentation, etc: GWT (or else it would not be on this list now would it? :P) Data access layer: Spring/Hibernate/postgreSQL client side validation: GWT-Validation Flow: Not yet decided if i am going to use Spring Web Flow or plain old GWT Deployment environment: Tomcat 5.5 or later I thought about creating a second GWT Module to store my custom widgets What i'd like to ask you people is the following: 1)I've seen a couple of posts about Spring Web Flow but neither are simple enough for me to comprehend, has any of you had a pleasant experience integrating GWT and Spring Web Flow? if not, how do you implement flow control within screens, pages, etc 2)I am a bit confused about how i should organize my application (considering i just made the leap to web 2.0). For example, i used to split every application into several modules (LoginModule, ClientModule, SalesModule, etc) so every module could contain the services related to them. I guess that such modules should only exist on the server side adjusting to their role of service providers right? nevertheless, i thought they should have some kind of client counterpart in order to be able to access their services in a organized way, is this correct? 3)Most important, did i say something terribly wrong at the beginning of this mail? (you know, like, oh my god, this guy does not know what he is talking about kinda wrong) I think of GWT as a source of great power, however, i do not seem able to harness such power yet...

Re: Spring Security login forwarding to blank page issue
Perhaps this may help in providing an answer. When I log out from my app and go to a different browser tab and go to the URL of my app, I'd expect to see a login screen. Instead, it seems as though the browser is caching the page and attempting to make calls to my services. In the response to these services, the server (tomcat) is sending back the login page (since I'm not logged in) as a response. It seems like the correct approach in this case would be to make sure the browser attempts to refresh my entry point every time so that it will be redirected to the login. I've tried adding meta http- equiv=Pragma content=no-cache to the top of my html file to force this like so: html head meta http-equiv=Pragma content=no-cache meta http-equiv=content-type content=text/html; charset=UTF-8 But to no avail. Any ideas? I'm in uncharted waters here with this caching stuff so your help would be greatly appreciated.

Re: PHP and GWT
I use PHP+GWT all the time, it works great together.
The two important things I found I needed to know where
a) Communicating to/from php silently while the app is running. As Ian
says, this is done with RequestBuilder..
b) Passing variables to the gwt app before its run. (ie, its start-up
variables, or those specific to the page).
This can be done by using variables in javascript.
eg;
In the HTML before the GWT stuff:
script type=text/javascript
var Data = {
Username: Anonymous,
FieldA: data one,
FieldB: data two
};
/script
Then you can access that with just;
static Dictionary theme = Dictionary.getDictionary(Data);
Then theme.get() to retrieve each field.
Thus you can use php to echo data you want into the html in the form
of javascript variables, and gwt can read it in as a dictionary
object.

Re: RPC Serialization of abstract classes
Come on guys, hasn't anybody else used more than plain strings and ints with GWT RPC? Is this really a bug (not serializing correctly up on the inheritance chain) or am I doing it all wrong? Help!

How to replicate GWT's History.addItem in native javascript?
I need to add a history item to parent window from within a Frame, I
can do this in native javascript with just;
public static native void sendHistory(String arg) /*-{
$wnd.parent.document.location.hash=arg;
}-*/;
However, this triggers a refresh in IE.
Seeing as GWT's History.addItem() dosnt trigger a refresh, I
wondered how to replicate it in javascript. (so I can send it to the
parent frame).
Any ideas?

One of the neat things about GWT is that it's open source :)
You could take a look at HistoryImplIE6 to see (exactly) how GWT does it.

GWT build takes forever
I am trying to compile a GWT module located in a source folder with
quite a few files. I am using ANT builder to do this. Here is an
excerpt from my build file that shows the GWT compile target:
path id=gwt.project.class.path
fileset dir=gen /
pathelement location=${gwt.sdk}/gwt-user.jar/
fileset dir=${gwt.sdk} includes=gwt-dev*.jar/
fileset dir=${smartgwt.sdk} includes=smartgwt*.jar/
fileset dir=lib includes=**/*.jar/
/path
!-- This is the target responsible for compiling GWT class files
into JavaScript --
target name=GWTCompile depends=compileApp description=GWT
compile to JavaScript
java failonerror=true fork=true
classname=com.google.gwt.dev.Compiler
classpath
pathelement location=src/
path refid=gwt.project.class.path/
/classpath
!-- add jvmarg -Xss16M or similar if you see a
StackOverflowError --
jvmarg value=-Xmx512M/
!-- Additional arguments like -style PRETTY or -logLevel DEBUG --
arg value=${app.gwtmodule}/
/java
/target
My issue is that running this build script takes forever (let's say
30 min on a Pentium D, I haven't tested it for longer). I think it
has to do with the fact that there is a huge amount of source in the
src directory and huge number of resulting class files in the gen
directory. My GWT module touches only 1% of the rest of the source
though. Is it possible to optimize the GWT compiler such that it only
looks at the source reachable from the module (i.e. source that the
module calls)? So far, all that I can think of is specifying the
minimal amount of inherits in the gwt.xml file.
Thanks,
Mayur

Re: Is there size limitation on data passed thru GWT-RPC?
Hi Zmitro,
Glad to know that you figured this out. Either workaround would work, with
the following considerations:
1) If you go with setting the server to not zip responses with
application/json content-types, any other JSON data that is sent from your
server outside GWT RPC payloads won't be gzipped, which could hurt if you do
have other resources that are served under application/json content-types.
2) Overriding shouldCompressResponse() might be the better solution given
the caveat in 1). There is the possibility of handling this in GWT core, but
given that double-zipped responses is a specific enough corner-case, it
probably makes more sense to handle it on the server or in
application-specific server-side code.
Hope that helps,
-Sumit Chandel
On Tue, May 26, 2009 at 6:06 AM, Zmitro Lapcjonak idob...@gmail.com wrote:
More details: the data is gzipped by GWT-RPC on server-side
class RPCServletUtils
writeResponse()
{
byte[] responseBytes = responseContent.getBytes(CHARSET_UTF8);
...
ByteArrayOutputStream output = new ByteArrayOutputStream
(responseBytes.length);
gzipOutputStream = new GZIPOutputStream(output);
responseBytes = output.toByteArray();
...
response.getOutputStream().write(responseBytes);
}
and then the zipped array was zipped second time
by the SAP server:
class GzipResponseStream
public void write(byte b[], int off, int len)
{
if( len = buf.length )
System.arraycopy(b, off, buf, count, len);
else
gzipmultistream.write(servletoutput, b, off, len);
}
On the client-side the browser unzips the response only once
(regardless of two content-encoding: gzip headers :)
And then GWT-RPC client-side code tries to decode the response:
class RequestCallbackAdapter
onResponseReceived()
{
String encodedResponse = response.getText();
// but the this is zipped json, not encoded text.
// and thus
caught = new InvocationException(encodedResponse);
}
So, as solution I can add application/json to list
of content-types which are not zipped by the server.
Or override the shouldCompressResponse() of
RemoteServiceServlet and return false there.
Additional solution is to create bug ticket to GWT-RPC
client-side, which doesn't try to unzip response :)

Manual Serialization / Deserialization of objects
Hi Guys -
I'm trying to write my own custom transport solution for client /
server communication so that I can make my project work cross-site. I
would like to serialize objects on the client side, send them to my
Jetty server using my own custom transport, and then deserialize those
objects on the server side for handling.
I've written the client code, and it seems to be working. It looks
like this:
(not that NetworkPacket implements IsSerializable, and EventService is
a dummy RemoteService)
public String serializePacket(NetworkPacket np)
{
String retVal = null;
SerializationStreamFactory fact = (SerializationStreamFactory)
GWT.create(EventService.class);
SerializationStreamWriter theSW = fact.createStreamWriter();
try
{
theSW.writeObject(np);
retVal = theSW.toString();
}
catch(Exception e)
{
e.printStackTrace();
}
return retVal;
}
This code seems to be working (it produces a reasonable-looking
string). I can't test if it deserializes though because the
serialization is asymmetric. The part I can't figure out though, is
how to deserialize on the server side. The closest I've found is the
ServerSerializationStreamReader class, which I found while poking
through the GWT source. It seems to be undocumented though, and its in
the com.google.gwt.user.server.rpc.impl package, which tells me it's
probably not intended for use by my code. How am I supposed to do
this?
Any help will be greatly appreciated!

Cloning Panels
Hi Guys, Highly embarrassing question but not something i've come across until now. I have a list of panels that a user can select and open, we'd like the user to be able to open more than 1 of each panel should they require, but this ends up being an issue because you can't clone objects in GWT.

Browser compatibility issue??
It's my first app and this might be a newbie rite of passage. I've built an app for managing members of groups defined on an LDAP server. In both Firefox and Safari, the differences bewteen how the app looks is insignificant. However, in IE7 (don't have IE8 to test with) there are huge gaps between rows in vertical panels. The empty space between the rows looks to be about the same height as the rows themselves. Is this a compatibility issue or a code issue. I'm using GWT 1.6.4 for the Mac and doing my development in Eclipse. What do I need to do to fix it or where do I need to look to see what the problem might be?

Re: PHP and GWT
Thanks everyone for the help. I haven't run int any problems with it yet
because I haven't really done anything yet with both of them. I was just
wondering before I kept doing my research with GWT that it was possible
later down the road! =)
Thanks for the info, if I have any problems ill make sure to post them.
Also does anyone have any example code they don't mind sharing
that demonstrates passing data between the two?
Thanks!

I use PHP+GWT all the time, it works great together.
The two important things I found I needed to know where
a) Communicating to/from php silently while the app is running. As Ian
says, this is done with RequestBuilder..
b) Passing variables to the gwt app before its run. (ie, its start-up
variables, or those specific to the page).
This can be done by using variables in javascript.
eg;
In the HTML before the GWT stuff:
script type=text/javascript
var Data = {
Username: Anonymous,
FieldA: data one,
FieldB: data two
};
/script
Then you can access that with just;
static Dictionary theme = Dictionary.getDictionary(Data);
Then theme.get() to retrieve each field.
Thus you can use php to echo data you want into the html in the form
of javascript variables, and gwt can read it in as a dictionary
object.

When the user clicks on the button a simple database lookup is performed and the flextable is populated and made visible. The problem is, the TabPanel does not expand to accomodate it. I only see the first couple of rows of the tab panel. There is no scrollbar, but I can scroll the window by selecting the table and dragging the mouse inside of it. Changing tabs and changing back causes the window to resize. I have not been able to find a redraw method or any other way to force the widget to update to accommodate the larger child. I've tried setting it to invisible and back to visible again to cause it to resize, but nothing I can do from code seems to have any effect.

Re: RPC Serialization of abstract classes
I (and presumably many others) am serializing things from an inheritance hierarchy without any problems. I can suggest two things for you: (1) reduce your code to the simplest working code that will show the problem, and then append that code to the issue you created. The source you posted to this thread didn't include all your code (eg State wasn't there) (2) Have you tried stepping through the GWT RPC code in a debugger to see if the data gets written out and it if then gets read in? This should tell you where the problem lies. Paul mirceade wrote: Come on guys, hasn't anybody else used more than plain strings and ints with GWT RPC?

Re: Button.click() not working
Thanks Ian. I see your great help to others here. You information
resolved the problem.
Explaining what I was trying to do to others, I am developing a GWT
view using the MVP pattern. It is because a I want to use as minimal
as possible GWTTestCase or GWTTestSuite. They are slow to start run.
So I prefer to use conventional JUnit tests whenever possible.
But there are cases where the only way to test is calling directly the
View. In that cases GWTTestCase and GWTestSuite come to rescue.
What I was trying to do is to ensure that when i click in a button in
the view, the expected delegation to presenter is done. Some code:
* * *
@Override
protected void gwtSetUp() throws Exception {
viewTask = new ViewTask(ObjectMother.getConstantsStub
());
RootPanel.get().add(viewTask);
};
public void

Maybe GWT should throw an error if it's not attached, but it doesn't.

Hello All,
The following code is not throwing a RuntimeException. Someone here
know why?
button = new Button(button);
button.addClickHandler(new ClickHandler(){
�...@override
public void onClick(ClickEvent event) {
throw new RuntimeException(.onClick() not implemented);
}});
button.click();
...
My version of GWT is 1.6.4. The one that came with google eclipse
plugin for Eclipse.
Thanks for any help.

Re: GWT build takes forever
On Jun 1, 4:25 pm, Pandaman p4nda...@gmail.com wrote: My issue is that running this build script takes forever (let's say30 min on a Pentium D, I haven't tested it for longer). I think it has to do with the fact that there is a huge amount of source in the src directory and huge number of resulting class files in the gen directory. My GWT module touches only 1% of the rest of the source though. Is it possible to optimize the GWT compiler such that it only looks at the source reachable from the module (i.e. source that the module calls)? So far, all that I can think of is specifying the minimal amount of inherits in the gwt.xml file. The GWT compiler aready does this. I'm not familiar with SmartGWT but it may be partly to blame here. Anything which does something nontrivial with a huge number of classes may prevent that code from being discarded and this would increase compile times and the size of the final script output. You may want to try running with slightly more verbose logging (-DlogLevel=DEBUG) and tee that to a file. You can then review it to see if there is a lot of things being pulled in you might not expect. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Manual Serialization / Deserialization of objects
Can you eloborate on your goals (re: cross-site)? I'd like to
understand the motivation so I can comment on the approach. Obviously
there is a reason why cannot make use of RemoteServiceServlet, but I'm
not sure I know why.

Hi Guys -
I'm trying to write my own custom transport solution for client /
server communication so that I can make my project work cross-site. I
would like to serialize objects on the client side, send them to my
Jetty server using my own custom transport, and then deserialize those
objects on the server side for handling.
I've written the client code, and it seems to be working. It looks
like this:
(not that NetworkPacket implements IsSerializable, and EventService is
a dummy RemoteService)
public String serializePacket(NetworkPacket np)
{
String retVal = null;
SerializationStreamFactory fact = (SerializationStreamFactory)
GWT.create(EventService.class);
SerializationStreamWriter theSW = fact.createStreamWriter();
try
{
theSW.writeObject(np);
retVal = theSW.toString();
}
catch(Exception e)
{
e.printStackTrace();
}
return retVal;
}
This code seems to be working (it produces a reasonable-looking
string). I can't test if it deserializes though because the
serialization is asymmetric. The part I can't figure out though, is
how to deserialize on the server side. The closest I've found is the
ServerSerializationStreamReader class, which I found while poking
through the GWT source. It seems to be undocumented though, and its in
the com.google.gwt.user.server.rpc.impl package, which tells me it's
probably not intended for use by my code. How am I supposed to do
this?
Any help will be greatly appreciated!

Re: GWT VS GWT-EXT
Hi, As I see the world, GWT is newer than EXT (javascript library) and a lot more robust. GWT-EXT is a port of EXT so that it works with in the GWT (java souce code) framework. In general they do the same thing, GWT-EXT looks nicer, but GWT is more generally developer friendly. EXT was written by web developers and comes from a web developer mind set (usually modifies the DOM directly), where GWT was written by people who are web developers but have more of a traditional GUI (Swing, SWT, AWT, VB exc) mindset (seems to have the concept of double buffering, or in other words writing to a off screen DOM for things that aren't visible). However on the oppisite argument GWT-EXT has some featurs that are built in to it, that GWT does not yet have. Most notibly Drag and Droping Object between Grids (Tables) and Trees. Sorting in Grids and dragging (reordering) columns in the Ext Grid. Another way of saying this is that the GWT-EXT grid behaves like a swing Table, and the GWT FlexTable behaves more like a swing Grid Bag Layout (for a panel). Answering which one is 'Best' really depends on what your trying to do... Hope this helps, Scott On Jun 1, 6:18 am, Amzad Basha amzad.ba...@gmail.com wrote: Please refer:http://gwt-ext.com/ Cheers!

Re: Browser compatibility issue??
Preliminary screwing around with my code suggests a solution to the IE7 problem. The following code works as expected in Firefox and Safari: VerticalPanel entries = new VerticalPanel(); entries.setStyleName(bottom20-padding); The expected behavior is that there is 20 points of padding at the bottom of the panel (padding-bottom: 20px;). But IE7 puts the padding between each row of the vertical panel. If I remove the style setting then the rows stack properly (the latter row immediately beneath the former). Since I can achieve the same results in the display by adding an additional empty row or adding another empty panel as filler, I can get around the problem but that seems to me to be a very awkward way to work around the issue. Is there a simpler solution? Thanks, Rob On Jun 1, 1:58 pm, Rob Tanner caspersg...@gmail.com wrote: It's my first app and this might be a newbie rite of passage.

EditorGridPanel rendering problem
Hi, I am using GWT 1.6.4 and GWT-Ext 2.0.6. I am trying to use EditorGridPanel and facing rendering problems. When the module loads I create a Panel (TopPanel) with BorderLayout and add that to the ViewPort. I then create another Panel (CenterPanel) and add EditorGridPanel, three buttons to the center of the BorderLayout Panel (TopPanel). I tried many layouts for CenterPanel but still not able to get what I want. I want the table to showup with the required data and scrollbars. All the three buttons comes below the table. The data for the table come via Async call when the module loads, so when the screen is rendered to the user, the data is populated in the table. But looks like the table gets rendered with no data and when the async process finishes the table gets populated but don’t get resized to fit the screen so only show me one row. The problem is with the Grid, I am not getting any scrollbars. Secondly I don’t want to define the height and width of the Grid. I want it to take as much as possible and show scrollbars, just like we do in html table by setting width and height as 100%.

GWT-RPC and Axis2/JAX-WS with Jetty Problem
Hi Guys, I have created the appropriate client/server side classes using GWT- RPC, also i am trying to connect to a J2EE Web Service, so I have tried using both JAX-WS and also Apache Axis2 to generate the java client proxy and stubs to connect to the service, which both works fine. But in either case (it doesnt matter which I use) when I go to host the GWT Project (Module) configured with Google Web Toolkit Host Mode using Jetty, i get import errors. It seems that the web service's client generated code at runtime can not be seen, which is weird as the .java source code is compiled and place inside the WEB-INF/classes directory, The jetty console output received - Loading an instance of module 'amwac' - Refreshing module 'amwac' - Refreshing module from source - Validating newly compiled unit - Errors in 'file.the java class.java' - Line 6: The import . cannot be resolved Any ideas what the problem might be would be appreciated --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: GWT-RPC broken in GAE/J
Glad to see progress on this. Ray, did anything come out of discussions at Google I/O? There seems to be two schools of thought here (both equally valid approaches mind you): 1. Help the client participate in the persistence, maintain detached state, dirty field lists, etc. This seems lofty and makes me more concerned about tight coupling, but is probably exactly what is needed for some applications. 2. Make a clean cut and keep the client free from persistence concerns. This could be RPC with seperate DTOs or marshalled XML/JSON. The client is only able to save by sending the modified object which is then fully updated in the database (all fields, since we lost track of what changed). This would typically happen by having the server reconstruct the object (unmarshal), then merge this over an existing entity. Our app actually functions as #2. Currently we use GWT-generated XML conversion code on the client. It's inefficient if your entity has many fields and you change just one. We've employed sparse xml to help, where we send back only the elements we want to modify (all of them are optional). When this is applied to the entity, only one field is triggered in the update. In theory this is great but I haven't implemented to dirty field tracking in the client, so in practice we serialize the whole object and we don't get any benefit from it. So I guess I'm sort of sitting on fence on this one. I beleive #1 can work, but I need to see proof of it in a large-ish app before we go and touch anything.

I don't feel the current hacks are production worthy. You have mentioned on your blog that you use protobufs for DTOs. Could you please elaborate on that? P.S.

[gwt-contrib] Re: possible ant changes
Hey Freeland, All of this sounds great. The build scripts have been in severe need of tweaking for a while, and I'm glad that you've decided to tackle this tricky issue. I've got a couple of comments about the ant test behavior. If it is the case that a subsequent ant build after running ant build is zero work provided that there are no code changes, then I am okay with having ant test depend on ant build. However, if running ant build in a zero-work case takes a non-trivial amount of time, then we should re-consider having ant test depend on ant build. I'd also recommend that running ant test rebuild the test classes themselves, and the build step for test code should be zero-work if ant test is run back-to-back with no test code changes in-between. A nice-to-have (i.e. less important than all of the other things you mentioned) would be the ability to specify specific tests via the command-line (maybe via a system property?).

Since -do would no longer exist, it wouldn't depend on dist to get the fan-out effects, and fan-out can be more selectively controlled. - Untangle whatever our double-build is caused by; at first blush, it seems to think my directories are out of date relative to the existing jar (not the files in them, but the directories themselves). - Change the default target to dist, for back compatibility, since that's what build today really does (build depends on -do which depends on dist which depends on build in all the subprojects). - Twiddle the semantics of build to be just building. I haven't decided whether that would include building samples (probably; buildonly exists to skip that), but it wouldn't assemble the distro archive and then unpack it as dist does. - Introduce user/test_dollar and user/test_underbar as java-root directories with the obvious subset of files from today's user/test, and an adjustment to the test target one or the other is on classpath, controlled I think by a system property.

It will be the case that the second of two back-to-back ant build commands will be zero work. (I think I have that part already, though I've gotten interrupted into FF 3.5b4 issues.) I'd also recommend that running ant test rebuild the test classes themselves, and the build step for test code should be zero-work if ant test is run back-to-back with no test code changes in-between.

A nice-to-have (i.e. less important than all of the other things you mentioned) would be the ability to specify specific tests via the command-line (maybe via a system property?). That actually exists already, mostly, in that the little-known ant property gwt.junit.testcase.includes is an ant-style glob of tests to run. Its default value is **/*Suite.class, but you can override that to a narrower value if you like. What's missing, however, is the ability to anything fancier than a glob, like say a comma-separated lists. So you can easily restrict to a directory's suites, to to a specific suite, but it's harder to run say the RPC and I18N suites at once.

[gwt-contrib] Removal of JMethod JParameter constructors
It looks like the following constructors were recently removed: public JMethod(JClassType enclosingType, String name) public JParameter(JAbstractMethod enclosingMethod, JType type, String name) I realize they're just convenience constructors, but a third party library we're using depends on these constructors, so I was wondering if someone could shed some light as to why they were removed? I couldn't find any discussions regarding it. Thanks. - Amir --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
