Re: GWT Serialization ???
Hi, Thanks for our reply, well I was considering doing DTO but thought there were a better way to do it. I hoped someone had a better way. But Ok I getting to it creating my DTOs. Cheers, Jero On Mar 26, 6:20 pm, Jason Essington jason.essing...@gmail.com wrote: If you don't have access to the source for your hibernate objects, then you'll need to create DTOs (data transfer objects) that are essentially identical to your hibernate objects. You can then manually marshal the values, or use a bean mapping library such as Dozer to do the work automagically. I generally use this technique even when I have the source for my server side objects as most of my objects have information that is not appropriate to send to the client anyway. -jason On Mar 26, 2009, at 7:41 AM, jero wrote: Hi, I am new to GWT and I have been playing around with GWT.

Re: how to easily plug-in a mock remote service
Would this help? Mocking GWT Asynchronous Services (with JMock) http://www.jmock.org/gwt.html Note that this example doesn't even require a GWTTestCase, which means your tests will run much faster, but you won't get any of the JavaScript support offered by hosted mode. This might require restructuring your code a bit so you're not invoking any GWT library code that uses native JavaScript (e.g. widgets) or GWT.create(), but I've found having more of these fast tests helps keep my state of flow while coding. If you do have widgets in your test, you can also use GWTMockUtilities to mock those as well - assuming they get passed in as dependencies. Would this work for you?

Re: RPC Performance/Response Problem
Hi Lord-67 I don't think your selection of data structure for the data transfer will make nuch material difference. Your observation that 500 strings works hunky dory, but 10,000 doesn't is pretty much my experience. The issue is divided into two parts: first the time taken to assemble, serialize and then deserialze the List of objects. Second the time taken to render the objects in a widget. You may not know this but it takes browsers an appreciable amount of time to render thousands of items - each one has to have a number of HTML boxes drawn for it. Test this yourself by making a simple test Tree created from some nested for loops on the client, and you will see that once you get up to 1500 or so TreeItems it starts to slow down noticably, and round about 5000 it takes seconds to draw. Note also different browsers give different performance in some situations, so you need to consider that too. Another important thing is that RPC is *much* slower in hosted mode than it is deployed in web mode (in case you haven't rumbled that yet). You can try two approaches to solve this: the classic lazy load, and the FastTree approach. In the lazy load approach you fetch only a screen full of items at a time (in a tree you would get just the top level items etc). next link fetches the next batch. This usually produces a response time from the user's perspective of 0.5s, which for them is a good as instant. Therefore although technically each page flip is slow (involving a fresh RPC call for each page) it is not perceived as such, the user does not have to wait seconds for the data to load. In the fast tree approach you fetch all the data in one RPC call, but only actually draw screen full at a time, using the full list as a backing model instead of making a fresh RPC call for each page. This makes navigating the items in the UI very fast once the data model is loaded because only the visible HTML boxes required are actually drawn, but you pay a pre-loading price up front in the big RPC call. Which is best depends largely on your application and user requirements and also on the precise time it takes to fetch the entire list over RPC. For example if your users will routinely want to sort, filter or search through a large data set in complex ways, then they will probably thank you for implementing the fast tree idea and be happy to wait maybe 2 or 3 seconds to fetch the all data up front because the subsequent operations will be much faster. On the other hand if a 1 item list is unusual, or they would normally only be interested in first page of two (typical for search results for example) then the classic lazy load is almost certainly best as it gives them a much quicker render of the first screen full. I'd say the first thing to do is to is to time your RPC call round trip separately from your screen render times to get a feel for the numbers, but do this in web mode either over web or on LAN, whichever is appropriate for your typical user, in a selection of popular browsers. regards gregor On Mar 27, 10:35 am, -Lord-67 -lord...@web.de wrote: No, i haven't tried that so far, i will do so and let you know if it's getting better.

Re: RPC Performance/Response Problem
Hi gregor, thank you for this detailed answer. First: I'm not sure if i understood everything since english is not my first language as you might have noticed. Sorry if i misunderstood something, i do my best. You're right what belongs the selection of data structure. I tried that and it makes no difference using a String[] or a ListArray of Strings to use as return value for the RPC. I know that rendering thousands of items takes some time, but that's not what i do with the data. I already use a model like you described in FastTree. I just fetch all the data (in my case paths to images in a String[]) from the server via RPC and show the user just 10-50 pictures per page. I create only 10 images (100px*100px) + a paging menu (first tab) and 2 tables(grids with fix size) (second, third tab). In my opinion rendering these few items (say max. 50) is not the problem, right? The kind of model you described as LazyLoad is something i also thought of, but i liked the idea of waiting one time for about 3 seconds and working on this set without having to wait any more (this is what my users would like most). That's why i haven't tried it so far. I already measured the RPC call round trip time, think i haven't said that clearly enough in my first post: - Starting the RPC (sending search parameters via RPC to the server): (no time i could measure in ms - 0ms) - server gets data per SQL statement and puts it into a String[] (the return value of the RPC): This step takes less than 200 ms [i measured the time from the start of RPC on server until the last statement, before return myStringArray; ] - server serializes the data and sends it to client which deserializes it: This step takes about 5 SECONDS [i measured the time from sending the RPC to the server until i got the first answer on the client with onSuccess() and substracted the 200ms ] - client saves the data in a lokal String[] and uses some of them to load and render 10 pictures and 2 tables: This step takes 1.2 seconds [i measured the time from onSuccess() beginning to the end ] So i am no step forward so far, but: I think i didn't test it in web mode for a long time (why should i, everything was fine on hosted and on web mode in the beginning and hosted mode is much easier for a quick test) so i will try that and hope it solves the problem. I will tell you the results on monday since i am not working the next two days. Thanks all for the help so far!

Re: Unable to find 'com/apress/gwt/GWTasks.gwt.xml' on your classpath;
Something on line 36 of GWTTask.java is null. If it isn't obvious from looking at your code what, exactly, is null, then you can set a breakpoint and run in debug mode (possible from the command line, but why make things difficult? Just use Eclipse or some other IDE). If you then can't figure out why whatever it is is null, post the relevant code. I'm going to take a wild guess and say you have something like RootPanel.get(foo).add(something) and there isn't an element with ID of foo in your HTML. But that is, again, simply a wild guess.

Re: Whats the GWT equivalent of urlencode?
Well, something is being encoded as 2F by php, and not being decoded. (along with a lot of other random changes) I'm most certainly not getting the same strings in/out with urlencode(String) on the php side and URL.decode(string) on the java side. My tests where just with random generated strings, I expected just to confirm it was the same, but it dosnt seem to be. I just want a guarantied way to communicate between php and gwt with preservation of *all* characters frankly.

Re: Back Refresh button handling
You can not rely on this event being raised before the browser is
closed. You can use the onunload=someJavascript() on your body tag
and then some JSNI to call your google code.
Here's the problem: the event gets raised, and you start doing your
work. The window gets closed before you finish doing your work, and
your rpc never completes and the server never knows.
I'd say at best you get a 50% success rate with the window close
events :)

When the user closes the browser window, I want the application to

server from their session. So I use the onWindowClosed() function to
take care of this... But when the page is refreshed, the session gets
logged out as well through the same function. This is something I want
to stop from happening. Any suggestions?

Hi
There is no way in GWT to distinguish betweenRefreshbuttonclick and
Window closebuttonclick. But you can trackrefreshbuttonwith a
little trick. You should use a time cookie which will expire after
some time. So whenrefreshbuttonis pressed, in on module load of
entry point , track the value of this cokkie, if this cookie is still
alive, this meansrefreshbuttonis pressed. The time this cookie will
expired should be considered. It should be very little.
Second for history, you should save your information in Session on
window close and then ifrefreshbuttonis pressed, get your
information from this session.

You can restore state, but it's a bit more work than just using GWT
History. Basically you'll need to come up with some way of modifying
the url search parameter (stuff after the #) to include some info so
that you can bring the userbackinto the same state as they were
before. For example, if your application has a number of screens and
they were on screen foo, which was loading with properties for an item
with id 10 then you'd need that information in the Url.
ex: http://yourApp.com/gwtHostPage.html#screen=foo_id=10
You could also put a conversation id in the url param and then keep
the fine details cached on the server, but that makes the state/data
more transient. If you go with an option like this though it can help
make your pages open and work in other tabs and even make points in
your application bookmark'able'.
Now for the easy answer, yes you can just prevent the user from
carelessly clickingrefresh. Fortunately there isn't a way to trap
somebody on a webpage (think about how bad the web would be). But,
you can use the WindowCloseListener to present a user with a
confirmation before they close the window, navigate to a new page, or
hitrefresh. It'd look something like this (not tested):
/
Window.addWindowCloseListener(
new WindowCloseLisener(){
public String onWindowClosing(){
return Are you sure you want to leave this application?;
}
public void onWindowClosed(){
// Cleanup if need be
}});

Another question, is there a way to trap Refresh click before
actually the app refreshes and can be cancel the event?

Re: Whats the GWT equivalent of urlencode?
Sorry (doh!) forward slash, not backslash. Ian http://examples.roughian.com 2009/3/27 Ian Bambury ianbamb...@gmail.com Sorry, I didn't read your first post, just the one I replied to. This is not a uniquely GWT problem, it is a PHP/JavaScript problem (as GWT just calls a JS function) PHP encodes differently to JS. The only problem I am aware of (maybe other people can chip in here) is PHP encoding the backslash. '()*~! all seem OK, but I haven't had too much involvement with this. If no-one comes up with a better solution then a simple replace might be the best answer. Ian http://examples.roughian.com 2009/3/27 Thomas Wrobel darkfl...@gmail.com Well, something is being encoded as 2F by php, and not being decoded. (along with a lot of other random changes) I'm most certainly not getting the same strings in/out with urlencode(String) on the php side and URL.decode(string) on the java side. My tests where just with random generated strings, I expected just to confirm it was the same, but it dosnt seem to be. I just want a guarantied way to communicate between php and gwt with preservation of *all* characters frankly. (as I may want to send encrypted strings, I dont want to worry about what characters I can use/not use in the encyption). ~~ Reviews of anything, by anyone; www.rateoholic.co.uk Please try out my new site and give feedback :) 2009/3/27 Ian Bambury ianbamb...@gmail.com: 2F is a forward slash which doesn't get encoded therefore doesn't need decoding 5C is the backslash which works OK for me Ian http://examples.roughian.com 2009/3/27 Thomas Wrobel darkfl...@gmail.com That was the one I tried already, it dosnt decode backslash's correctly. (that is +%2F isnt decoded) Thanks anyway. ~~ Reviews of anything, by anyone; www.rateoholic.co.uk Please try out my new site and give feedback :) 2009/3/27 mel mpedzi...@stuart.iit.edu: Its URL.encode(String) from the com.google.gwt.http.client package. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Back Refresh button handling
The way I solve this is that a timer on the server cleans up sessions
that haven't had activity in a while.
It's a little bit simpler for me since I have a stateless setup with
the session id simply being used for authentication purposes.
I think that's the most robust approach - you don't need to maintain
complicated state information in the server. You simply have a
permissions based approach as to whether or not a user is allowed to
modify global resources the client-side takes care of state.

You can not rely on this event being raised before the browser is
closed. You can use the onunload=someJavascript() on your body tag
and then some JSNI to call your google code.
Here's the problem: the event gets raised, and you start doing your
work. The window gets closed before you finish doing your work, and
your rpc never completes and the server never knows.
I'd say at best you get a 50% success rate with the window close
events :)

I'm in a similar predicament, perhaps you might have an idea of what
to do.
When the user closes the browser window, I want the application to
logout his/her session automatically so as to free up memory on the
server from their session. So I use the onWindowClosed() function to
take care of this... But when the page is refreshed, the session gets
logged out as well through the same function. This is something I want
to stop from happening. Any suggestions?

Hi
There is no way in GWT to distinguish betweenRefreshbuttonclick and
Window closebuttonclick. But you can trackrefreshbuttonwith a
little trick. You should use a time cookie which will expire after
some time. So whenrefreshbuttonis pressed, in on module load of
entry point , track the value of this cokkie, if this cookie is still
alive, this meansrefreshbuttonis pressed. The time this cookie will
expired should be considered. It should be very little.
Second for history, you should save your information in Session on
window close and then ifrefreshbuttonis pressed, get your
information from this session.
Thanks and regards

You can restore state, but it's a bit more work than just using GWT
History. Basically you'll need to come up with some way of modifying
the url search parameter (stuff after the #) to include some info so
that you can bring the userbackinto the same state as they were
before. For example, if your application has a number of screens and
they were on screen foo, which was loading with properties for an item
with id 10 then you'd need that information in the Url.
ex: http://yourApp.com/gwtHostPage.html#screen=foo_id=10
You could also put a conversation id in the url param and then keep
the fine details cached on the server, but that makes the state/data
more transient. If you go with an option like this though it can help
make your pages open and work in other tabs and even make points in
your application bookmark'able'.
Now for the easy answer, yes you can just prevent the user from
carelessly clickingrefresh. Fortunately there isn't a way to trap
somebody on a webpage (think about how bad the web would be). But,
you can use the WindowCloseListener to present a user with a
confirmation before they close the window, navigate to a new page, or
hitrefresh. It'd look something like this (not tested):
/
Window.addWindowCloseListener(
new WindowCloseLisener(){
public String onWindowClosing(){
return Are you sure you want to leave this application?;
}
public void onWindowClosed(){
// Cleanup if need be
}});

GWT provides History.onHistoryChange event to handle history but how
can we restore application state when a user clicks onRefreshbutton?
For example the user performed multiple actions on the web site and
then clickedrefreshbutton. Now how using GWT History class we can
restore the same state?
Another question, is there a way to trap Refresh click before
actually the app refreshes and can be cancel the event?

Problem with Element.getFirstChildElement()
I think I may have found a GWT bug. Please let me know if there is a
better place to post this...
Consider this code from a JSTL tag…
div id=existingFriendsAddressBook
ul
c:forEach items=${friends} var=friend
c:set
var=friendEmail${fn:toLowerCase(friend.email)}/c:set
li
input type=checkbox
id=existingFriend_${friendEmail} / $
{friendEmail}
/li
/c:forEach
/ul
/div
…and this GWT code, which tries to get a reference to each of the
checkboxes created in that tag…
@Override
protected void build() {
DivElement existingFriendsAddressBook =
DivElement.as(DOM.getElementById
(existingFriendsAddressBook));
UListElement list =
UListElement.as
(existingFriendsAddressBook.getFirstChildElement());
NodeListNode children = list.getChildNodes();
int numFriends = children.getLength();
for (int i = 0; i numFriends; i++) {
LIElement row = LIElement.as((Element) children.getItem(i));
Element firstChild = row.getFirstChildElement();
InputElement checkbox = InputElement.as(firstChild);
String checkboxId = checkbox.getId();
[do stuff with checkboxId, unrelated to this post]
}
}
It turns out that IN FIREFOX ONLY, the variable “firstChild” is
null, and I believe this is a bug in Element’s getFirstChildElement
(). I changed the code to the following, and there is no longer an
error…
LIElement row = LIElement.as((Element) children.getItem(i));
NodeListNode subchildren = row.getChildNodes();
InputElement checkbox = InputElement.as((Element) subchildren.getItem
(0));
String checkboxId = checkbox.getId();
A call to GWT.getVersion() returns 1.5.2
As you can see, I have found a work-around, so this isn't urgent...
just a heads-up! :)

Changing application path in production
Hi, I was wondering if there is a way to set up your gwt application such that something which I normally access as: http://xyz.com/abc/com.foo.bar.gwt.client.Main/Main.html could be accessed as http://xyz.com/abc/ I am using apache infront of tomcat at the moment, and I thought about using something like mod-proxy or one of the similar apache plugins to map from http://xyz.com/abc to http://xyz.com/abc/com.foo.bar.gwt.client.Main/Main.html. However I was hoping people may have been using a different/better approach to this.

[gwt-contrib] Review: JsArrays patch
Scott, we already talked about this, but here's the patch for public review.
The basic goal is to surface the native length, sort, push, and shift
operators for JsArrays... I know you mentioned that IE6's push may be slower
than indexed extension, and thus a candidate for deferred binding, but I
wanted to get a basic implementation in first.
There should be only checkstyle changes from what we discussed (though that
obviously doesn't help the rest GWTC). I also added some checkstyle fixes
to JavaScriptObject, introduced by my c5082.

final class JsArray extends JavaScriptObject {
...
public int getInt(int index) {
assert indexIsInBounds(index);
return getIntImpl(index);
}
public void setNumber(int index, double value) {
assert isNumber(value);
setNumberImpl(index, value);
}
private native int getIntImpl(int index) /*-{
return this[index];
}-*/;
private native void setNumberImpl(int index, double value) /*-{
this[index] = value;
}-*/;
...
}
/** Public API */
public final class IntArray extends DataStructure {
public static IntArray create() {
return JavaScriptObject.createArray().cast();
}
protected IntArray() {
}
public int get(int index) {

[gwt-contrib] Re: Review: JsArrays patch
I think the argument is more for unnecessary rather than bad...
although without JsArrayBase (we can make it package-protected, and call it
JsArrayImpl if anyone cares), we duplicate the JSNI implementation for a
couple trivial methods. I thought refactoring them into one place was nice,
but trivial enough that I'm not fighting over it. Revised patch attached; I
can go either way on this.

[gwt-contrib] Re: GWTC compiler disallows using a derivative of AsyncCallback on async interface declaration
hmm... i looked and there appears to be a simple fix.
private static String computeInternalSignature(JMethod method) {
StringBuffer sb = new StringBuffer();
sb.setLength(0);
sb.append(method.getName());
JParameter[] params = method.getParameters();
int i = 0;
for (JParameter param : params) {
sb.append(/);
JType paramType = param.getType();
if (i++ == params.length - 1) {
paramType = getAsyncCallbackSignature(paramType);
}
sb.append(paramType.getErasedType().getQualifiedSourceName());
}
return sb.toString();
}
getAsyncCallbackSignature simply checks to see if there's a way to
cast the paramType to AsyncCallback. If there is, then it returns the
equivalent AsyncCallback JType. If there isn't, it returns the
original JType.
Haven't looked at the JType API to see how getAsyncCallbackSignature
would be written. I'll try to look at it Tuesday evening when I have
some time.

Ok - i'm almost positive it is the same problem. I think the loadplugin thing is a misdirection. The project appears to crash compiling the code.

The basic goal is to surface the native length, sort, push, and shift operators for JsArrays... I know you mentioned that IE6's push may be slower than indexed extension, and thus a candidate for deferred binding, but I wanted to get a basic implementation in first. There should be only checkstyle changes from what we discussed (though that obviously doesn't help the rest GWTC). I also added some checkstyle fixes to JavaScriptObject, introduced by my c5082. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
