You must have missed something during the move, as I'm successfully using a FormPanel+FileUpload from within a DecoratedPopupPanel (not a DialogBox as there was an issue in IE when coupled with the GlassPanel from the Incubator). Or is it a DialogBox vs. DecoratedPopupPanel discrepancy? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Why use GWT?
I do the same but i hold all my gwt modules in a single project. One of these gwt modules is the common module. Named Common . hehe I don't need to jar anything in order to be shared. And eclipse helps refactoring things from one module to the Common. All modules are compiled and errors are showed from all modules at the same time. sorry my english.

Add a new row in a table dynamically!!!
Hi, I wanted to know if it is possible to add a new row to a existing html table dynamically using GWT. I am fairly new to GWT and was wondering if its possible. I checked the forum and couldn't find anything on this. If anyone has a solution for this please let me know.

Re: How to do cross site implementation in GWT
Hi Manish, Your code looks fine to me. I am new to this so I dont know much in detail, but you could try this. Compile the Java code to pretty javascript. use -style PRETTY argument to compiler. The use firebug in firefox and debug the javascript. In the scripts tab, select the xx.cache.html file. Your code will be in this file. Actually it will be by the end of this file. Then put a breakpoint in the method that gets invoked on button click. Then click on th button... and debug the values you are passing and other things. Hope you will find the issue. Let us know when you do.

Re: Exception handling in GWT Service
I am sorry... my bad... I read it as SerializationException
Looked at the SerializableException in gwt... it is just an Exception
implementing IsSerializable interface... so it all makes sense.
Thanks Ravi for clarifying.
BTW, in 1.5 gwt supports serialization of objects implementing
java.io.Serializable.
So just by extending Exception it would work.
Thanks again,
Jossey.

Re: Add a new row in a table dynamically!!!
Hi Rakesh, As Javier says, you can use FlexTable (which extends HTMLTable) using methods insertCell(..) and insertRow(..). You can also do this with Grid (also extends HTMLTable) using resize(..), resizeColumns(..) and resizeRows(..). FlexTable is a bit more complicated than Grid because cells can occupy more than one row or column like a collage. Grid is a straight "four by two" type effort, and for, say, adding an extra row of table style data would probably be the simplest choice. regards gregor On Nov 26, 6:08 pm, jamer <[EMAIL PROTECTED]> wrote: > You can use the widget FlexTable and their row can be HTML > > Javier Mejías --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Need to richer widget set in GWT
I've been working with GWT for over a year now and working with GWT- EXT for about 6 months and I went to the Google I/O conference. I was wondering if there was an effort to build up GWT widget set to the level of polish of GWT-EXT? The widgets that matter most to me are: 1. Sortable table/grid 2. Grouping table/grid 3. Paging table/grid 4. Dragable pop dialog (Having action buttons at the top right of the dialog) 5. Tab Panel (GWT is missing the mouse over and table scrolling) 6. Calendar date field (With date picker) 7. ComboBox (Image support, z-indexable) In addition, I think it would be very helpful if GWT had some basic CSS templates like EXT's default, gray, and vista templates. Please let me know if the GWT team is planning on building these features. If not, let me know if anyone is interested. Because I'll build them and post them somewhere. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to do cross site implementation in GWT
One thing I just noticed in your code is that you are exporting java
methods to javascript. When I tryied that a few weeks ago I could not
figure out how the instance expression part worked, so I only have
tried this with static methods
e.g.
public static int displayDialog(String companyId, String companyName) {
ResponseDialog.getInstance().doSplash(companyId, companyName);
return 0;
}
public static native void exportJavaMethod() /*-{
$wnd.sendEmail =
@com.fbg.client.Emailer::displayDialog(Ljava/lang/String;Ljava/lang/String;);
}-*/;
and then calling the function from any javascript code in the host as
sendEmail(id, name)
Perhaps you can try changing PMGWTHtmlUtils::invokeGWT to be a static function

Re: Need to richer widget set in GWT
Not native to the GWT library, but check out http://www.jroller.com/sjivan/entry/smartgwt_1_0_released Smart GWT has a lot of nice things, similar to GWT-EXT. Is your main issue with GWT-EXT that it is not open source/free?

Re: javascript error getBoxObjectFor ?
Hi Ed,
Which browser is this occurring on? Also, could you try compiling your GWT
application with the -style PRETTY flag to generate human-friendly output
that should be easier to debug? That'll make it so that the generated code
isn't obfuscated, so we might be able to identify which specific method and
variable function BBc(a) and the parameter 'a' are referring to.

Re: javascript window.opener not working
Hi gabidp,
I believe the reason why you're unable to access the opener attribute
defined on the $wnd object is because of the way you're creating the popup
in the first open(url, name, options) call.
The reason why we keep the $wnd reference around is because GWT applications
load up in their own , meaning that references to the regular window
object are local to the rather than the body of the page.
By calling open(url, name, options), you're actually invoking
window.open(url, name, options) from within the context. This means
that the popup might also limited to the same scope, so references to $wnd
attrributes won't resolve.
Try replacing the open(url, name, options) call by $wnd.open(...) and see if
that works.
Hope that helps,

Re: Serialization questions
Hi jon918, Please see my replies inlined below: 1) In 1.5 there is now support for managing the serialization using > the SerializationStreamFactory on the client. However on the server, I > don't see how I can retrieve the SerializationPolicy for my module > without using a GWT RPC call. Must I use the default serialization > policy to take advantage of this feature? The serialization policy file is generated as a security measure to make sure that types you're sending across the wire are indeed the ones you intended to deserialize when they come back to the server. If you're using the SerializationStreamFactory on the client-side for custom serialization, I would imagine that you're either using a non-Java backend or doing something interesting with a Java backend. In case it's the former, you shouldn't need to worry about the serialization policy file and instead add extra security considerations around whatever is deserializing code on the server-side. If you are using a Java backend, is there any reason why you can't use GWT RPC with a mix of custom field serializers as needed for any special needs? Basically, more information on what you're trying to do here would give us more to go on about why / how you need to get the serialization policy file while using non standard GWT RPC. 2) RpcServletUtils.writeResponse double-buffers the output when it > gzip's the response payload. Why is this done instead of writing > directly to the response output stream? Is sending the content length > critical for some reason? > I'll have to check on this one and get back to you. I don't think that sending the content-length is terribly important, however it could be useful for things like download progress notifications and so on. 3) Are there plans to open up the RPC APIs more than they are today in > general. I believe that making GWT APIs refactored and opened up has been and will be an iterative process. We've had some major improvements in the linker subsystem (now refactored and pluggable) as well as improvements in GWT RPC (such as the refactored SerializationStreamFactory). I think it's safe to say that you can look to better and better designs to make the GWT APIs more easy to extend and modify.

Re: Need to richer widget set in GWT
Yeah being free is very important. Also I would like it to be pure GWT, not GWT wrapping JS. Also I've found GWT-EXT to have weird errors every once in a while. This smartGWT looks to be the same thing as GWT-EXT just with a little more widgets. Way can't GWT make the next step and have it's whole rich tool set. I want to the incubator to see what was in the works and to be honest I was a little disappointed. I'm thinking about asking if I can help.

Re: Simple app for DB view (?)
The gwt-incubator has PagingScrollTable widget that provides
pagination. if you want to try you can follow
http://code.google.com/p/google-web-toolkit-incubator/wiki/MakingIncubatorBetter
and get the latest version of the project. There are a example, how
use the widget.
Basically you need
1) Define a table model derived from MutableTableModel that is used to
fetch data. This code is executed at the client. Relevant code:
public class ClienteTableModel extends MutableTableModel {
@Override
public void requestRows(
final Request request,
final
com.google.gwt.gen2.table.client.TableModel.Callback
callback) {
Servico.Util.getInstance().requestRows(request, exemplo,
new
AsyncCallback>(){
public void
onFailure(Throwable caught) {
callback.onFailure(new Exception("falha rpc"));
}
public void
onSuccess(SerializableResponse result) {
callback.onRowsReady(request, result);
}
});
}
2) Servico.Util.getInstance().requestRows is a class that is called on
the server using RPC. That's why We need to provide an AsyncCallBack
to that is going to be executed assyncronously when the server
responds, and feed the widget with data on callback.onRowsReady
(request,result).
You need to follow some small rules to let gwt rpc do its magic:
An interface and it's Async countepart which is code shared between
server and client. (Im my case i have just one project) Removed the
import, for brevity
An interface celebrating the contract between the server and the
client:
package unipac.client;
@RemoteServiceRelativePath("servico")
public interface Servico extends RemoteService {
public SerializableResponse requestRows(Request request,
Cliente qbe);
public static class Util {
public static ServicoAsync getInstance() {
return GWT.create(Servico.class);
}
}
}
An interface counter-part that . Note that its methods returns void.
The SerializableResponse that the above interface returns
will be got by the callback object. Code Shared between the client and
the server too. It's necessary due the asyncronous nature of Ajax
calls.
package unipac.client;
public interface ServicoAsync {
public void requestRows(Request request, Cliente qbe,
AsyncCallback> callback);
}
Finally the implementation... (server code only)
package unipac.server;
public class ServicoImpl extends RemoteServiceServlet implements
Servico {
public SerializableResponse requestRows(Request request,
Cliente qbe) {
SerializableResponse result = null;
Session sessao =
HibernateUtil.getSessionFactory().openSession();
Transaction tran = sessao.beginTransaction();
Criteria crit = sessao.createCriteria(Cliente.class)
.addOrder(Order.asc("nome"))
.setFirstResult(request.getStartRow())
.setMaxResults(request.getNumRows());
if (qbe != null) {
Example exemplo = Example.create(qbe).ignoreCase().enableLike
(MatchMode.ANYWHERE);
crit.add(exemplo);
}
result = new SerializableResponse( crit.list() );
tran.commit();
return result;
}
}
Things to note. ServicoImpl implements the first interface and
extends from RemoteServiceServlet (Yes this is a servlet). Look at
requestRows parameters: Request is used to tell the server the
starting row and the number of rows, in order to limit the results.
Cliente qbe is an object that im passing from the client to the server
to query by example which instances I want. The code uses Hibernate,
not JPA but you probably can understand.
3) Back to client side. you need:
a) Instantiate the table model.
ClienteTableModel tableModel = new ClienteTableModel();
b) One tableDefinition
TableDefinition tableDef = createTableDefinition();
private TableDefinition createTableDefinition() {
// Create the table definition
DefaultTableDefinitiontableDefinition = new
DefaultTableDefinition();
// Set the row renderer
String[] rowColors = new String[] {"#DD", "#EE"};
tableDefinition.setRowRenderer(new
DefaultRowRenderer
(rowColors));
// Nome
{
AbstractColumnDefinition columnDef =
new
AbstractColumnDefinition() {
public S
Re: Problem with writing JSNI wrapper for ActiveMQ ajax code
When you say it does not work, exactly what error do you get? >From what I can see it looks like it should work so long as your ActiveMqCallback class has an onEventArrived method definition, and that you cont have a typo in "com.yht.gwt.client.ActiveMqCallback::onEventArrived".

Re: add a external JAR problem
Hi vitor, The rules are: 1. the library jar must include source as well as byte code if you need any of its classes compiled by the GWT compiler for client side use. 2. in addition those classes must be compatible with GWT JRE Emulation - see list in GWT docs for supported subset of Java 1.5. 3. this does not apply to libraries used by GWT RPC servlets server side where you can use whatever you want. regards gregor On Nov 26, 6:36 pm, vitorLundberg <[EMAIL PROTECTED]> wrote: > Hello, > Before posting here I read some post with the same kind of problem > but I didn't really understand how to use it. > > So I have a gwt project that's use a external jar, is a char4j > ( library to build charts). > but I get this error : > > [ERROR] Line 85: No source code is available for type > com.googlecode.charts4j.RadarPlot; did you forget to inherit a > required module? > > RadarPlot is under the charts4j.jar. > > So if I understood in my Project.gwt.xml I need to set a inherits > defining the sources path for all my charts4j classes. > > I don't know if it's the solution for this problem, and also how to > exactly do that ? > > regards, > Vitor --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT + MySQL Best Practices?
Hi guys, I'm developing a project with GWT + Servlets + MySQL. At this point, I've got the project setup using the "-noserver" flag and I have Connector/J configured on an external Tomcat 6 server so that my servlets can access the DB. Communication to/from server is through GWT-RPC . My Problem: This is a bit of a pain b/c anytime I make a change to the servlet code (which resides in the same Eclipse project as my GWT code...and I'd prefer to keep it this way), I have to copy the *.class file (for the servlet) over to the CATALINA_HOME/webapps/myproject/WEB- INF/classes/blahblahblah folder. This seems extremely manual and I'm hopeful that there's a better way to do it. What is the recommended way of doing this type of development? Ideally, I'd it would just pickup the changes to both the client and server code as it used to when I was working in hosted mode. Unfortunately, I couldn't figure out how to get MySQL and Connector/J setup in the integrated Tomcat, so I went with the "- noserver" option and configured it with an external instance of Tomcat instead. This manual copying crap is starting to get super annoying, so I'm reaching out for help. What's the best practices for this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT + MySQL Best Practices?
For automating the deployment (instead of manually copying) ant is the only way to go. I've heard stories that Maven is even easier, but we haven't jumped onto that band wagon (yet). When we build with no server, we have an ant build file that does all that, and then deploys to our external server. We do it old school and jump out to the file system and run via command line, but I've done from inside Eclipse as well.

Re: add a external JAR problem
Yes Gregor is right. I want to add one more point. A project is included or inherited in the .gwt.xml file only if that is a GWT project (atlesat to my knowledge). i have all other external jars in a lib folder and have them in my classpath. -Satya On Nov 26, 6:30 pm, gregor <[EMAIL PROTECTED]> wrote: > Hi vitor, > > The rules are: > > 1. the library jar must include source as well as byte code if you > need any of its classes compiled by the GWT compiler for client side > use. > 2. in addition those classes must be compatible with GWT JRE Emulation > - see list in GWT docs for supported subset of Java 1.5. > 3. this does not apply to libraries used by GWT RPC servlets server > side where you can use whatever you want. > > regards > gregor > > On Nov 26, 6:36 pm, vitorLundberg <[EMAIL PROTECTED]> wrote: > > > Hello, > > Before posting here I read some post with the same kind of problem > > but I didn't really understand how to use it. > > > So I have a gwt project that's use a external jar, is a char4j > > ( library to build charts). > > but I get this error : > > > [ERROR] Line 85: No source code is available for type > > com.googlecode.charts4j.RadarPlot; did you forget to inherit a > > required module? > > > RadarPlot is under the charts4j.jar. > > > So if I understood in my Project.gwt.xml I need to set a inherits > > defining the sources path for all my charts4j classes. > > > I don't know if it's the solution for this problem, and also how to > > exactly do that ? > > > regards, > > Vitor --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hi Jorge Are you able to create your application with GWT? Yes Eclipse is THE tool for java applications.

Re: Exception handling in GWT Service
There is a SerializationException
(public class SerializationException
extends java.lang.Exception) in gwt1.5.
SerializableException is depricated in 1.5
I shall try your suggestion of extending the Exception or use the
SerilizationException and post the code here.
Thank you both for your help,
Appreciate it

web.xml or .gwt.xml?
Hi, I have read the lengthy post about servlet descriptors for hosted mode vs. deployed mode. http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/36f8c197279d159/ed4f5bbc972bc6b8?lnk=gst&q=web.xml#ed4f5bbc972bc6b8 According to this, I should put my and and so on in tomcat/webapps/ROOT/WEB-INF/web.xml for hosted mode. Howewer, I find that in practice I have to put them in myapplication.gwt.xml, like this If I do that, and not put my servlet in the aforementioned web.xml, it works fine in hosted mode. So that is great, if unexpected, but now I want to add a parameter for my servlet, along these lines: MusicUploadService org.cafesip.gwtcomp.server.FileUploadServlet action-class mypackage.MyActionClass This is from the API for (org.cafesip.gwtcomp.server Class FileUploadServlet) How do I add the to my gwt.xml file?

changing keyboard input language
Hi all, Just started dev with GWT. I am able to change the current keyboard input context in pure java using the InputContext class so that when I change the language in my app, the keyboard automatically changes to that language. Now, is there an equivalent or similar way to do this in GWT. My web client has a drop down list to select different languages which my server returns the appropriate info in the selected language. However, I still need to manually change the keyboard input on the MS WIndows XP System Tray to be able to enter data in the selected language. All help is appreciated.

Re: Why it's so slow?
Andrey schrieb: > Most of the time is spending after the message: > " > ... > Computing all possible rebind results for > 'com.acme.client.AddressBookService' > ... > ". When building a GWT-application, for all browser- and language- variants a complete compile will be performed. So one minute is not too much, e.g. my current application needs two minutes for two languages and the standard set of browsers. Every resulting html-page containing the JS-code is about 1MB big. > So, how is it possible to develop anything with such a speed? First of all, one minute is nothing. In the Good Old Times [TM] the build of something non-trivial took a significant time much more than one minute. In hosted mode, a press on refresh is all you need, if you have changed classes concerning the client-side and functionality on the server-side is better developed by writing a JUnit-test that actually test all the functionality (not only the one that is happening when pressing a button on a GUI). That's much faster than building the complete application and try out by entering values into the GUI and pressing the button.

Re: Why it's so slow?
The GWT Compiler does a massive amount of optimization and it does so for each of the browsers. This process takes a lot of time. GWT has it's own browser that runs your Java code with less compilation work (and lets you debug your Java code instead of the generated JavaScript). To access this functionality in Netbeans use "Debug Project" instead of "Run Project". You should also look here: http://lemnik.wordpress.com/2008/07/27/fixing-compilation-in-gwt4nb/ For a patch to the default build.xml thats generated by gwt4nb (it stops the GWT Compiler running when it doesn't need to). Hope that helps.

Copying (clone) of JavaScriptObject
Before I start to rely on this, I wanted to know if this is a valid
technique for cloning a JavaScriptObject and whether there are any
limitations I might run into.
The situation is that I'd like to clone a 'settings' object so
instances of this class I build using it are immutable. I understand
it's not a deep clone, but I don't think it's necessary in my case.
private static JavaScriptObject cloneJSO(JavaScriptObject src) {
JSONObject srcObj = new JSONObject(src);
JSONObject dstObj = new JSONObject();
for (String key : srcObj.keySet()) {
dstObj.put(key, srcObj.get(key));
}
return dstObj.getJavaScriptObject();
}
Thanks!

Re: Exception handling in GWT Service
Hi,
Why are we extending SerializableException?
Is that because the starting example had it so?
I think it kinds of gives out a wrong message. ...
just extends Exception should do.
not very relevant to the discussion anyways...

Re: hot code replacement in external module
Hi, The .gwt.xml will be used only when you compile the Java code to javascript. So you will not be deploying the .gwt.xml. Setting the user.agent and locale properties are just to make the development cycle faster. And when you actually do the final build you would not use these properties. I guess you would be able to use the embedded server even if you have integrated the server side to spring. I found this approach some where in the net, but don't remember where. Anyways, if we could map all your remote services to path like /services/ XService then we would be able to map the spring dispatcher servlet to /com.abc.xyz.XYZ/services/*Service or /com.abc.xyz.XYZ/services/* I am not sure whether .../*Service worked correctly for me. .. Well... now... will this actually solve the problem changes to the service not reflecting on the fly. I think it will not. I am not sure though... i was developing a prototype and had no time to investigate. I think the GWTShell uses its own class loader and that is how it handles dynamic loading of the changes. And when we took a different path - the spring dispatcher - we lost this feature. But yes the client changes will be reflected because it goes thro GWTShell. Theoretically... G, if you r trying this out pls let us know whether all this makes sense. Thanks, Jossey.

Re: Is Run Time Annotation Possible?
Hi Zujee,
AFAIK, it is not possible to modify annotations during runtime (on the
client side). Annotation modification would require reflections which
is not supported on the client side.

Re: Exception handling in GWT Service
Jossey
Quite the contrary, actually. I started off with a custom exception
which was merely a child class of Exception that I intended to use in
RPC calls (i.e. service methods throw it). This actually didn't work
in the ways expected, i.e. when the server threw the exception I was
unable to retrieve the exception message in the client, or find out
what the cause was. Which is when some digging around revealed that if
you want to send the exception over the wire, it has to be a GWT
SerializableException.
This is with 1.4.6x, of course this may have changed in 1.5.x, I am
not sure.

Re: How to do cross site implementation in GWT
Hi Manuel, Thanx for response.But I wanna know how do you passing the parameter from our website/HTML to gwt component. is this by using JSNI.if yes , how do attached your compiled gwt app source to your website/html.This point is crucial for me since i am not able to connect to gwt from our html in deployment mode( not hosted mode ). please provide the detail about your approach.

Re: web.xml or .gwt.xml?
Servlet configuration in module definitions (gwt.xml files) is for *simple* servlets. It's enough to get you started, but once your project reaches any siginificant level of complexity, you need to use the -noserver option for hosted mode and provide your own app server. You configure that app server as you normally would.

How to remove a MenuItem's sub menubar?
How can I dynamically set & remove a menu item's sub menubar? If I set the sub menubar to a new empty instance of MenuBar then I get runtime IndexOfOfBounds errors when the user hovers where the sub menubar would be. If i set the the sub menubar to null it crashes when it runs. If I get the parent menubar and remove the item, I can't put the item back at the same location again because there is no addItem that allows placement/index to be specified. How can I dynamically add/remove a sub menubar? -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

FormPanel form = new FormPanel("_blank"); // equivalent to
target=_blank in HTML
form.setAction("http://action_script";);
form.setMethod(FormPanel.METHOD_POST);
// TODO: add some panels and your controls

Re: Bundle RPC calls
Nothing official that i'm aware of, although GWT provides some nice Command helper classes. IncrementalCommand should do what you need it to do I imagine. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

If you do this, you'll likely lose the form's autocomplete (just
guessing, I haven't tried it)

You could move the DOM element, not the widget (this means you won't
have your FormPanel as a child of your VerticalPanel, and your
VerticalPanel will be in some kind of "inconsistent" state: its DOM
structure has been changed without it being notified, so some things
might break).

That's the Best Thing (TM) to do IMO. Why would you like to avoid this
approach?
