interesting idea, but i would point this issue to the google code or to the google docs team, because gwt is only using this system.

Compiling source files form external project?
Dear all, I'm writing a GWT app which has three tiers: a client, an RPC server (using the GWT RPC mechanism) and a further back-end server (RMI) used by the GWT service. Some classes, containing data, are used by all three tiers. Hence they are placed in package com.myapp.common . Since these classes do not really belong to a distinct tier, i placed them in a separate project. But since they ARE needed by the client, i DO want the GWT compiler to translate them. My problem: how can i tell GWT (1.5.3) to translate these classes? (Without moving them into the client project because that would just be ugly.) Is there a way to have the source tag in the .gwt.xml file refer to a package stored in an external project? Thanks, Mike BTW: in an earlier project, using GWT 1.4 instead of 1.5 i did the same thing and that compiled without problems. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

For example: Name, Address are two Stack Panels, Name Text boxes with First name Text Boxes with last name Address Text boxes for Address 1 Text Boxes for Address 2, City, State, Pin .

gwt-rpc + webservices hang glassfish 2.1
Hi all,
I'm getting some strange hangs with glassfish and gwt rpc services.
I'll describe my problem:
my dev tools are: netbeans 6.5 with latest updates, glassfish 2.1,
gwt-1.5.3, linux ubuntu 8.04.
situation:
on the entry point create a SimplePanel with a button. Associate to
this button a listener with the following code to be executed:
for (int i = 0; i 10; i++) {
_query_service.doQuery(query, new AsyncCallback()
{
public void onFailure(Throwable caught)
{
}
public void onSuccess(Object result)
{
Window.alert(wh0a);
}
});
}
The doQuery () is a GWT-RPC service.
The service implementation is something like this:
public class QueryServiceImpl extends RemoteServiceServlet implements
QueryService
{
@WebServiceRef(wsdlLocation = WEB-INF/wsdl/client/StoreService/
localhost_8139/Store/StoreService.wsdl)
private StoreService service;
public synchronized doQuery (MyObject query) {
try
{ // Call Web Service Operation
com.my.company.Store port = service.getStorePort();
// TODO initialize WS operation arguments here
java.lang.String programName = par1;
java.lang.String programVersion = par2;
// TODO process result here
java.lang.String result = port.getCfgText(programName,
programVersion);
out.println(Result = +result);
}
catch (Exception ex)
{
// TODO handle custom exceptions here
}
}
}
as you see the webservice is called with the automatic 'call
webservice operation...' by Netbeans.
The webservice in hosted in the local server, the same in which the
gwt-rpc service is deployed.
But in the above configuration I've a *global* freeze of glassfish. I
must restart it to have it responding again. No exception is thrown
nor result received.
The method is thread-safe, using synchronized keyword.
The hang does not happen if the webservice is hosted on another
server.
The hang does not happen if I call once the doQuery (), and then I the
for loop.
Am I missing or doing something wrong?

Re: Help with DecoratedStackPanel
Here, check this out. It has source code to get you started as well: http://gwt.google.com/samples/Showcase/Showcase.html#CwStackPanel You will only need one stack Panel, but have a StackPanel.add() for Name and for Address. For something like Name and Address, StackPanel seems like an odd choice. You may want to look at the rest of the GWT Showcase and see if something better fits what you are looking for.

Re: Compiling source files form external project?
I `solved' my problem by creating a separate module for the common source files, packaging them in a JAR, and including them in the client project by using inherits. Not really satisfied though, because each time i change the common package i must re-export and import the JAR.

Several options: a) refactor your code so that client and server code are in distinct classes b) include a super-source/ in your module with a dummy java.net.Socket class so that the GWTCompiler doesn't choke (but it won't use it in the final code as the server only method won't be called by client code).

Re: Excluding imports on client side

Obviously i get an error when importing java.net.Socket. Several options: a) refactor your code so that client and server code are in distinct classes b) include a super-source/ in your module with a dummy java.net.Socket class so that the GWTCompiler doesn't choke (but it won't use it in the final code as the server only method won't be called by client code).

JNSI - IFrame - Function Issue
Hey guys,
I'm trying to create a simple little foray in to JSNI to do some DOM
manipulation and I'm really striking out bigtime. Basically, my
document loads an IFrame that contains and external page in it. On the
page is a JS function called giveFocus(). I can't seem to get ahold
of the frame properly to call the function.
Has anyone got this to work sucessfully? Basically, I've got something
like this:
entryPoint
{
Frame myFrame = new Frame( *externalPage* );
myFrame.setSize( 100, 200 );
RootPanel.add( myFrame );
doFrameFunction( myFrame );
}
native void doFrameFunction( Frame frame ) /*-{
$wnd.frames( frame ).document.callThisJSFunctionInsideTheIFrame();
}-*/;
The pseudocode is crappy but generally that's what I'm trying to pull
off.
Is this possible? Where am I going wrong?
Thanks!
Evan

Re: JSNI / OpenLayers
It is a little clearer now, couple of things were no correct in my
code and it took a while to get everything a little more straight.
I performed the following : click on an openLayers point to launch
java function. It works like that :
First, my native Js function largely inspired by Openlayers example
page :
---
private static native JavaScriptObject _select(JavaScriptObject map,
JavaScriptObject layer,VectorLayer x)
/*-{
var mylayer=layer
function select(feature)
{
x...@org.gt.client.map.openlayers.geometry.vectorlayer::selected
(Lcom/google/gwt/core/client/JavaScriptObject;)(feature.attributes[0])
}
var drawControl=new $wnd.OpenLayers.Control.SelectFeature
(
mylayer,
{
clickout: true,
toggle: true,
multiple: true,
hover: false,
toggleKey: ctrlKey, // ctrl key removes from
selection
multipleKey: shiftKey, // shift key adds to
selection
box: true,
onSelect:select
}
);
map.addControl(drawControl);
drawControl.activate();
}-*/;
---
Note that :
Those three objects are passed JavaScriptObject map, JavaScriptObject
layer,VectorLayer x (VectorLayer is the self reference of the class :
this)
The path to the class in JSNI context is :
x...@org.gt.client.map.openlayers.geometry.vectorlayer
To adress a function in my class :
x...@org.gt.client.map.openlayers.geometry.vectorlayer::selected()()
On 10 mar, 15:26, Gilles gilles_ta...@yahoo.fr wrote:
We are using GWT andOpenLayersin several projects making use of theJSNI.
Until now we could use simpleOpenlayersjs function such as Zoom. It
was clear to me that to use a zoom usingJSNII have to do :
private static native void _zoomTo(JavaScriptObject map, int
zoomLevel) /*-{
map.zoomTo(zoomLevel);
}-*/;
I could do a lot with this simple methods. But now, as complexity is
increasing I would need to use more complex feature ofOpenlayers.
For example what would be the smartest way to apply those settings to
my map so I can detect double click and get the event to my gwt
application :
script src=../OpenLayers.js/script
script type=text/javascript
OpenLayers.Control.Click =OpenLayers.Class
(OpenLayers.Control, {
defaultHandlerOptions: {
'single': false,
'double': true,
'pixelTolerance': 0,
'stopSingle': false,
'stopDouble': false
},
initialize: function(options) {
this.handlerOptions =OpenLayers.Util.extend(
{}, this.defaultHandlerOptions
);
OpenLayers.Control.prototype.initialize.apply(
this, arguments
);
this.handler = newOpenLayers.Handler.Click(
this, {
'click': this.trigger
}, this.handlerOptions
);
},
trigger: function(e) {
var lonlat = map.getLonLatFromViewPortPx(e.xy);
alert(You clicked near + lonlat.lat + N, +
+ lonlat.lon + E);
}
});
var map;
function init(){
map = newOpenLayers.Map('map');
var click = newOpenLayers.Control.Click();
map.addControl(click);
}

I created the 2 packages as explained: - StockWatcher.client - StockWatcher.server Now when I try to run this app in hosted mode, I get the follwoing error: java.lang.ClassNotFoundException: StockWatcher.server.StockPriceServiceImpl However, looking at my xml, I have: servlet path=/stockPrices class=StockWatcher.server.StockPriceServiceImpl / The souce file for this class is located at: src\StockWatcher\server\StockPriceServiceImpl.java And if I look directly in the folder hierarchy I find the class at: bin\StockWatcher\server\StockPriceServiceImpl.class My run configuration has the following Classpath: - GWT_1.5 - src - \StockWatcher\ In all likelyhood there is a problem with the ClassPath from what I read ... but I can't seem to find it or make it work.

Re: SerializationException when serialize a HashMap over RPC
The error message tells you exactly the reason: WeeklyAppointmentData is
not serializable. Please refer to the serialization rules of GWT
(essentially, your classes have to extends IsSerializable, all non-static,
non-final, non-transient fields must be serializable you must provide a
default constructor (any visibility, but it must be there).
Since you don't give the definitions for DayHourCoordenate Appointment, I
can't give you the exact reason, but one of those classes is at fault.

Re: SerializationException when serialize a HashMap over RPC
I think I see it. List is not generally serializable. The recommendation I
recall reading somewhere is to try to use super-classes as infrequently as
possible because it makes the compiler's job more difficult - also, in this
particular case, the GWT compiler is unable to determine the type to
serialize to.
Try:
private MapDayHourCoordenate,ArrayListAppointment mapData = new
HashMapDayHourCoordenate,ArrayListAppointment();
or even more preferable, change mapData to a HashMap as well.

JsArray.length giving error: HostedModeException: Expected primitive type int; actual value was undefined
I have the following code that processes a JavaScriptObject that is expected
to be a JsArray:

JsArray jsa = jso.cast();
int cnt = jsa.length();
I am finding that if the JsArray has a single element then jsa.length()
results in following exception.

Re: Using existing java API
There's nothing you can do. GWT *emulates* Java, but only part of it. If it doesn't emulate some part of it, you can't use it. Not on the client. You can use what you like on the server.

Invoke GWT entry point via custom JavaScript?
Hi All, I am currently trying to integrate GWT into my existing application, but Im having trouble doing that at the moment. Currently I have heaps of custom JavaScript that I will eventually migrate to GWT, but for now, I need to figure out how to add some custom GWT widgets into my page, but not on page load (as heaps of stuff is not yet loaded by the user, etc...) but rather on the response callback from an existing AJAX call, can this be done? Im imagining that I could call some externally exposed method that resided within the *.nocache.js file? But Im not sure how that all works, etc... If anyone has any resources that I could read up on or experience in this area, that would be great!

RequestBuilder
How do I wait for the response is completed in another class?
For example, I have a class called GetData
public class GetData{
private String query;
private String DEFAULT_URL = http://localhost/book.php;;
String result = new String();
public GetData(String query) {
this.query = query;
this.search();
}
private void search() {
String url = URL.encode(DEFAULT_URL + ?query= + this.query);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);
builder.setCallback(new RequestCallback() {
public void onError(Request request, Throwable
exception) {
}
public void onResponseReceived(Request request,
Response response)
{
if (Response.SC_OK == response.getStatusCode())
{
result = response.getText();
}
}
});
try {
builder.send();
} catch (RequestException e) {
}
}
public String getResult(){
return this.result;
}
}
So, when I call
GetData test = new GetData(query);
System.out.println(test.getResult());
will return nothing. But I'm sure that it will return something.
The problem is System.out.println(test.getResult()); is executed
before the result=response.getText();
How can I fix that?

Put the println in your async callback (or in a function called from your

Re: RequestBuilder
You can't send a request to a server in one line and expect it to have completed before you get to the second line. This will NEVER happen because JS is single-threaded and even if the request HAS returned, the callback will be queued to run later. If you order something from an internet web site, it won't be there immediately after you order it. You have to wait for it to be sent. The 'A' in Ajax is for 'asynchronous'. If you want to do something with the data you requested, you have to do it in the callback, or it won't be there. If you have a button which refreshes a table, get the button to make the request, and pass the table to the callback. Get the callback to update the table.

Re: RequestBuilder
No. If you did that, the whole browser would lock up until the call returned. You *could* run a timer and keep checking if the call had returned, but there is no point since when the call has returned, the callback function can do the work. You need to move any logic that needs the requested data to the callback (or have the callback make some method call on the object that needs the data). If you don't want to do that, you shouldn't really be using Ajax. That is what Ajax does. If you want to be a bit more specific as to your needs, or can come up with an example which mirrors what you are doing, you'll probably get more specific help. If you need to stop user input while the call is made, then the usual way is to put up a 'loading...' message, either over the whole screen, or just in the widget which is waiting.

Nope. See here:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/faca1575f306ba0f/3be719c021aa19bd
One option is to define a new callback interface and pass an instance
to GetData. That way you can define the instance in the other file
and still be a good browser citizen.
For example:
public interface SearchResultListener {
void onNewSearchResult(String result);
}
public class GetData {
public void search(String query, final SearchResultListener listener) {
String url = URL.encode(DEFAULT_URL + ?query= + query);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
builder.setCallback(new RequestCallback() {
public void onError(Request request, Throwable exception) {
// handle problems here
}
public void onResponseReceived(Request request, Response response) {
if (Response.SC_OK == response.getStatusCode()) {
listener.onNewSearchResult(response.getText());
}
else {
// handle problems here
}
}
});
try {
builder.send();
}
catch (RequestException e) {
// handle problems here
}
}
}
Then, if you have an instance of GetData, you can do this:
aGetData.search(query, new SearchResultListener() {
public void onNewSearchResult(String result) {
System.out.println(result);
}
});

Subject: [gwt-contrib] Please expose moveSelectionUp/Down methods in
FastTree
To: GWTcontrib Google-Web-Toolkit-Contributors@googlegroups.com
in gwt incubator's FastTree, moveSelectionUp and moveSelectionDown are both
private.
Please either make these methods protected, so that I can subclass FastTree
and make my own public api to call them, or provide a public API to controll
navigation.
It coudld be as simple as adding these two methods :
public void moveSelectionDown() {
moveSelectionDown(curSelection, true);
}
public void moveSelectionUp() {
moveSelectionUp(curSelection);
}
Alternatively, extract the logic from these methods into public static
helpers which I can call to determine the 'previous' and 'next' elements,
and then I can call setSelectedItem

[gwt-contrib] HashSet throwing incorrect exception possible compiler bug
First major concern is that I got a ConcurrentModificationException when
iterating over a HashSet - this exception is completely meaningless in the
context of the browser (no threading). There's also not really any
meaningful message in the stack trace:
00:20:24.446 [ERROR] Uncaught exception escaped
java.util.ConcurrentModificationException: null at
java.util.HashMap$HashIterator.nextEntry(HashMap.java:810) at
java.util.HashMap$KeyIterator.next(HashMap.java:845)
The relevant code that causes this is:
private HashMapModelAction, HashSetModelListener models;
// .
HashSetModelListener listeners = models.get(action);
if (listeners != null) {
for (ModelListener listener : listeners)
listener.modelUpdated(action, info);
}
Replacing it with a regular iterator:
IteratorModelListener iterator = listeners.iterator();
while (iterator.hasNext())
iterator.next().modelUpdated(action, info);
somehow fixes the problem. Is the compiler screwing up in converting the
Java for-each notation into the iterator equivalent, or am I missing
something?
Some background: this succeeds the first time it is called from within an
event handler context (to notify the model to perform a login attempt).
However, it fails the second time it is called when it is called from an
AsyncCallback context (returning the result that it was a successful
login). However, at no point is the HashSet used modified (after startup
where it contains currently 1 element).
Thanks

[gwt-contrib] Re: RpcRequestBuilder
My only criticism of this design is that it only captures a part of the use
cases where the transport mechanism needs override. That is, it helps in
cases where one is making HTTP requests, and needs to modify HTTP request
parameters or the body, but it leaves out the cases where one can't make
direct requests (using XHR). The RequestBuilder stuff is very tightly bound
to XHR.
The most famous and important example of this is writing gadgets using GWT
and RPC. You can't use XHR (not all proxies will pass it because of the
mime-type) and thus you must use the Javascript makeRequest() function, or
inject script tags and tunnel the payload over JSONP. I have implemented
both of these techniques, and it seems to me that the only way to do it is
to override the RPC generator. I have a module which overrides the
ServiceInterfaceGeneratorProxy to replace the ProxyCreator with one whose
RemoteServiceProxy method has an override on doInvoke().
The other reason to use makeRequest() is because it can leverage the gadget
container to sign the requests, so that the RemoteService can verify that
RPC request authorization.

should mention that this type must be unique per style sheet--people
might be using this to shift between different styles at runtime, right?
This is a nice trick. But it seems like you're assuming that stylesheets
are applied atomically after they load. Are you sure about that?

Kind of odd that this is mutable. I'd be more inclined to see it as a
constructor arg--that is, keep the two args constructor with default
timeout value, and provide a three args one to allow it to be set.

Thanks, John LaBanca jlaba...@google.com On Thu, Mar 5, 2009 at 9:36 AM, David david.no...@gmail.com wrote: Hi, Well, I just subclassed the ScrollTable and ProgressBar for now - I remove the widgets from the collection and add them in the onLoad and remove in onUnload, that works nicely. We have to release multiple applications the coming days so not much time to create a patch or even switch to a new release of GWT-incubator. I don't like the idea of using a Timer or even a WindowResizeListener in widgets... but I don't see any other way to getting some feedback when something changes in the DOM. It's a shame actually that DOM does not have such a native event - maybe we should propose something to w3c and hope that it gets included in our lifetime ? In case of the ProgressBar widget, I actually had an implementation that did not need to recalc the div blocks. It even supported a xor effect on the text showing the percentage (the incubator switches style when reaching 50%). But I threw it away when I got my hands on the incubator (less maintenance for me). I also had something implemented where all widgets in my DOM hierarchy would call a layout method when one of the other widgets resized somehow. But that meant that I had to implement this support in every widget I had in the DOM tree. And it was triggered every time a widget was added or removed. In a big UI that consumed a lot of CPU cycles and in many cases no resizing was needed. I switched to using the ResizableWidget approach and the performance is a lot better (and the code cleaner). I am not in favour of removing the timer. Components that need to know should find out automatically. In small projects you can easily manage this, but in larger organisations many bugs will arise because developers do not care about these fine details when developing. Also, we want to reuse busines UI objects in other UIs and then we need to expose these resizing problems to higher level UI components. Some of the components of GWT have a tendency to let the app developer handle the complexity and in many cases that can create very dangerous dependencies in code (spaghetti code we call it). The TabPanel is such a component: it attaches all children widgets right away, even when not in the visible tab. If you have a widget that depends on size calculations of the parent component then it breaks because the size will be 0. There is a solution ofcourse, to lazyly add the panel containing the widget - but that is more work for a developer that just wants to reuse an existing UI component. David On Thu, Mar 5, 2009 at 2:46 PM, Joel Webber ѯ(ټ)ѥ j...@google.comwrote: [cc'ing John, who IIRC wrote the resizable widgets] That does indeed sound like a bad thing. At the very least, it would be important to get that list cleared out so that it's not growing without bound. And yes, onLoad/onUnload would be the right time to do it. I'm also curious about your usage of these widgets. Are they used in such a way that it would be relatively easy to hook the window's resize event and iterate over them to give them a chance to resize? And do you think that would be sufficient to capture the times when they actually *need* to resize? I ask because I've always been slightly uncomfortable with the idea of resizing based upon a timer, but there's no better way to do so in the general case -- because any change to the DOM, text, CSS, or what have you can, in theory, cause a widget to resize. But I'm wondering if providing somewhat more limited semantics (along the lines of this widget needs to be told when its size changes, but it's up to the application to do so) would allow us to get rid of the timers altogether.

I don't have any data to refute that, but I'd offer that two of Google's major properties APIs: OpenSocial and FriendConnect flat out require non-XHR, and this touches services with export these APIs (now Orkut, Gmail, iGoogle, GFC, among others). And that anyone who attempts to create a cross-domain GWT application that uses RPC will run into it, to the extent that many GWT users just dump RPC and resort to JSON + script tag injection. It's one of the often repeated blog tutorials.

Forgive the intrusion. I'm not sure what constraints you're working
with, but why are you not better off loading the css through xhr and
creating a style element in the head? The downsides are you can't do
cross-domain loading of styles and that relative urls are resolved from
a different base url. But given that you already have to encode
something in the stylesheet (the reference style) the tradeoff seems
similar. Also, watching for a particular element to be non-zero seems
pretty fragile. A style like div { height: 400px; } would give you a
false positive on loading.
