Re: Error This UIObject's element is not set;
Hi Shi!
create a constructor for your MenuHome and move the code from the Composite()-
Method into this constructor.
Extending from Composite is correct! ^^
Don't know why you use a method for doing this... ;)
...
public MenuHome() {
VerticalPanel vPanel = new VerticalPanel();
// Do You really want to set the title (title = tooltip)?
// To see something create a Label with Text an add this to the vPanel
// Example
// Label label = new Label(Good!);
// vPanel.add(label);
vPanel.setTitle(GOOD!);
vPanel.setWidth(100%);
vPanel.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
initWidget(vPanel);
// Don't use this here (you do this on your entrypoint alright)
RootPanel.get().add(vPanel);
}
I hope i could help you... ;)

You can use or not use GWT RPC for whatever reason you like. But when you say you don't use GWT RPC because it's not RESTful, I think that carries no real meaning other than general FUD. It would be better to state the specific tradeoffs that don't work for you. I'm just concerned that some might avoid a very useful technology for a very questionable reason. Can you please shed some more light? 1. RPC: the method is in the request body, not as an HTTP method (not always possible though). 2. If I want a collection resource (GETting the resource returns me a representation of the list) and individual entry resources (that I could GET, PUT and DELETE –using method override in older Safari–, and eventually POST for other needs...), I need 2 RemoteService classes, and then using the EntryService means changing the service location before each method call; this is not the way GWT-RPC has been thought, GWT-RPC isn't resource-oriented, it's, well, RPC... 3. POST for everything, even for things that should have been GETs, PUTs or DELETEs; this makes HTTP caches unusable (which you might want, but not necessarily). etc. In brief: GWT-RPC is RPC (method calls), it's not resource-oriented. It tunnels within HTTP requests, but it isn't HTTP. Well, it's the same as SOAP, without the bloated XML serialization and minus the extensibility. GWT-RPC is good for prototyping, because it's easy to set up; but it isn't web-style, so it won't scale as well as RESTful web services (a book that I highly recommend, along with blog posts from Joe Gregorio). I guess generators could be used to make RESTful web services as easy as GWT-RPC (I didn't investigate yet, as our server-side language is... JavaScript!) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: #token fragment sometimes cause page reload, sometimes not?
On 17 sep, 06:09, Brice [EMAIL PROTECTED] wrote:
Good evening. I am working on a new GWT app and I noticed a few
strange behaviors in IE 7 that I didn't see in FireFox / Safari.
Particularly that a link with a #token will cause a page refresh if
its in my wrapper HTML, but not if its generated by GWT. This doesn't
happen (from what I can see) in FireFox / Safari.
Here's the scenario: my wrapper HTML has been designed externally, the
GWT just renders into the content area of the page. Outside of this
area are two tabs. Instead of linking to different pages, the hrefs
are #tabA and #tabB. After the GWT EntryModule has run, this *should*
just fire History changed events, right? That's what it does in FF and
Safari. In IE, it reloads the page, and since my EntryModule invokes
fireCurrentHistoryState(), the right state is initialized.
Within the GWT module, links are rendered with tokens, too. When these
are clicked, the page does not reload. As expected, the History
changed event is fired, and the new application state is loaded.
Am I going about this incorrectly? Is this an IE ideosyncracy?
Yes (search the issue tracker, this has been reported recently –maybe
it was you?–)
Is there a workaround?
Attach onclick handlers to your links to call History.newItem and
Event.preventDefault(). That's what GWT's Hyperlink do to workaround
this IE quirk.
To attach the onclick, you could loop through the
Document.get().getElementsByTagName(a) (before attaching your GWT
widgets) and call DOM.setEventListener and DOM.sinkEvents.
However, I'd rather expose the History.newItem method as a global JS
function through JSNI and attach the onclick handlers in the host page
HTML: a href=#tab1 onclick=GWT_History_newItem('tab1'); return
false;
Another option is to just have placeholders in your HTML host page and
inject GWT Hyperlinks in there (RootPanel.get(tab1link).add(new
Hyperlink(Tab 1, tab1))).
...if only there were a SimpleHyperlink widget with a static wrap()
method to wrap an A HREF and set the EventListener automatically...

Re: File write not working
Tomcat is keeping it's log-files in tomcat 6.0\logs or /tomcat6/ logs. Look for preferences to know what file that is, but basically you can just take the file with the last changed-date. Normally you'll find all Exceptions- or System.out.print-output-messages there. P.S. Is Linux your deployment environment?

GWT RPC Handling Session
There is a login-page on startup at my GWT-Application. The user
enters his login name and password and clicks a button to sign in. In
my server- implementation there is a method which should sign the user
in (and gets back a result- state):
...
public int loginUser(String user, String password) {
int result = -2;
// check's whether user name equals a valid email
if (Validator.validateEmail(user)) {
DB_User db = new DB_User();
// get request to create a session, when login for creating the
session later
// HttpServletRequest request = this.getThreadLocalRequest();
// login the user
result = db.loginUser(user.toLowerCase(), password, request);
}
return result;
}
...
In the loginUser- method of db I create the session:
...
HttpSession session = request.getSession();
...
I don't know how I have to handle the session. There must be a state
in the server- implementation which is compareable withe the current
session, because only there I can access the session with
this.getThreadLocalRequest().getSession();, or!? How do I check
whether the session is valid?
Hope you can help and thx in advance!

Handling ONCONTEXTMENU in GWT 1.5
Use Case
1. Disable browser context menu by default
2. Enable browser context menu on edit controls like EDIT boxes,
listboxes etc when such controls receive focus. This is required so
that you can do the normal highlighting, cut, copy and paste from such
controls
3. When edit controls lose focus, disable the browser content menu
again
4. Example
//disable browser context menu on main page
code
private static native void disableBrowserContextMenuJSNI() /*-{
$doc.oncontextmenu = function() { return false; };
}-*/;
/code
//enable browser context menu
private static native void restoreContextMenuJSNI() /*-{
$doc.oncontextmenu = function() { return true; };
}-*/;
Create edit box with preview that allows switching between disbaled
and enabled context menu
code
public class PreviewTextBox extends TextBox implements FocusListener {
public PreviewTextBox() {
this.addFocusListener(this);
}
public void onDetach() {
super.onDetach();
disableBrowserContextMenuJSNI();
DOM.removeEventPreview(m_preview); //tos - 1
}
public void onFocus(Widget w) {
DOM.removeEventPreview(m_preview); //tos - 1
DOM.addEventPreview(m_preview); //tos
restoreContextMenuJSNI();
}
public void onLostFocus(Widget w) {
disableBrowserContextMenuJSNI();
DOM.removeEventPreview(m_preview); //tos - 1
}
private EventPreview m_preview = new EventPreview() {
public boolean onEventPreview(Event event) {
int type = DOM.eventGetType(event);
switch (type) {
case Event.ONMOUSEDOWN:
Element target1 = DOM.eventGetTarget(event);
if (!
PreviewTextBox.this.getElement().isOrHasChild(target1)) {
disableBrowserContextMenuJSNI(); //by
defauly no browser context menu must show
DeferredCommand.addCommand(new Command() {
public void execute() {
DOM.removeEventPreview(m_preview); //tos - 1
}
});
}
break;
default:
break;
}
// But DO allow the event to fire.
return true;
}
};
}
/code
The above code was working perfectly in GWT 1.4.x
With the advent of GWT1.5, this nolonger works and I get the browser
context menu anyway.
Is there anything else I need to do to make the oncontextmenu event
work in GWT 1.5.
Also I noticed that now we have Event.ONCONTEXTMENU as an event bit.
I tried using EventPreview to stop the context menu from showing but
most of the times this event is NOT PREVIEWED! See example below
code
public boolean onEventPreview(Event event) {
int type = DOM.eventGetType(event);
switch (type) {
case Event.ONCONTEXTMENU:
Element target = DOM.eventGetTarget(event);
if (!
m_search_textbox.getElement().isOrHasChild(target)) {
DOM.eventPreventDefault(event);
DOM.eventCancelBubble(event, true);
return false;//dont allow to bubble break;
}
break;
}
return true;
}
/code
Any reason why it previews sometimes and not all the time.
Does it have anything to do with this line
GWT Widgets now sink their events lazily: widgets no longer routinely
sink their events eagerly. Instead, the event is sunk the first time a
listener is added to the widget. So subclasses which relied on eagerly
sunk events will now have to manually sink the events they depend
upon.

Re: overide browser context menu
It appears that the oncontextmenu event won't get previewed correctly in all
circumstances. I've entered issue 2895 to this effect.
If the code you mention above is no longer working, it is probably because
the oncontextmenu property is being overwritten by sinkEvents(). Try moving
it to after sinkEvents() is called on the element -- I believe that should
work for now.

Specifically, you at least need to call event.stopPropagation() (if it

anyway.
I don't believe it's possible to do this solely with mouse events, but
I could be mistaken.

Re: #token fragment sometimes cause page reload, sometimes not?
Brice,
I got similar problems when i was working on a GWT
application. In my case all History changes are triggered by my
application itself no external hyper links.(History.newItem()).
However sometimes IE7 reloads the page. I applied a FIX suggested in
the following thread.
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/26bb5d7cff3f1ab8/c71514aec8dc5703?show_docid=c71514aec8dc5703

I'll take a whack at this and report back if I have any further

Good evening. I am working on a new GWT app and I noticed a few
strange behaviors in IE 7 that I didn't see in FireFox / Safari.
Particularly that a link with a #token will cause a page refresh if
its in my wrapper HTML, but not if its generated by GWT. This doesn't
happen (from what I can see) in FireFox / Safari.
Here's the scenario: my wrapper HTML has been designed externally, the
GWT just renders into the content area of the page. Outside of this
area are two tabs. Instead of linking to different pages, the hrefs
are #tabA and #tabB. After the GWT EntryModule has run, this *should*
just fire History changed events, right? That's what it does in FF and
Safari. In IE, it reloads the page, and since my EntryModule invokes
fireCurrentHistoryState(), the right state is initialized.
Within the GWT module, links are rendered with tokens, too. When these
are clicked, the page does not reload. As expected, the History
changed event is fired, and the new application state is loaded.
Am I going about this incorrectly? Is this an IE ideosyncracy?
Yes (search the issue tracker, this has been reported recently –maybe
it was you?–)
Is there a workaround?
Attach onclick handlers to your links to call History.newItem and
Event.preventDefault(). That's what GWT's Hyperlink do to workaround
this IE quirk.
To attach the onclick, you could loop through the
Document.get().getElementsByTagName(a) (before attaching your GWT
widgets) and call DOM.setEventListener and DOM.sinkEvents.
However, I'd rather expose the History.newItem method as a global JS
function through JSNI and attach the onclick handlers in the host page
HTML: a href=#tab1 onclick=GWT_History_newItem('tab1'); return
false;
Another option is to just have placeholders in your HTML host page and
inject GWT Hyperlinks in there (RootPanel.get(tab1link).add(new
Hyperlink(Tab 1, tab1))).
...if only there were a SimpleHyperlink widget with a static wrap()
method to wrap an A HREF and set the EventListener automatically...- Hide

You can use or not use GWT RPC for whatever reason you like. But when you say you don't use GWT RPC because it's not RESTful, I think that carries no real meaning other than general FUD. It would be better to state the specific tradeoffs that don't work for you. I'm just concerned that some might avoid a very useful technology for a very questionable reason. Can you please shed some more light? 1. RPC: the method is in the request body, not as an HTTP method (not always possible though). What is the design tradeoff though? Why does a pragmatic developer care? 2. If I want a collection resource (GETting the resource returns me a representation of the list) and individual entry resources (that I could GET, PUT and DELETE –using method override in older Safari–, and eventually POST for other needs...), I need 2 RemoteService classes, and then using the EntryService means changing the service location before each method call; this is not the way GWT-RPC has been thought, GWT-RPC isn't resource-oriented, it's, well, RPC... I can't really understand any of that. What do you need to do that REST gives you and GWT RPC fails? 3. POST for everything, even for things that should have been GETs, PUTs or DELETEs; this makes HTTP caches unusable (which you might want, but not necessarily). etc. PUTS and DELETES are not required by REST. As for POST versus GET for inquiries, even within REST there are tradeoffs and minor misfits. You may use a POST form when you have a lot of parameters, even though your intention is to invoke a safe method, which POST does not give you by HTTP contract. In brief: GWT-RPC is RPC (method calls), it's not resource-oriented. It tunnels within HTTP requests, but it isn't HTTP. Well, it's the same as SOAP, without the bloated XML serialization and minus the extensibility. These answers are bsically REST religion. Assuming I have no religion, why do I care? GWT-RPC is good for prototyping, because it's easy to set up; but it isn't web-style, so it won't scale as well as RESTful web services (a book that I highly recommend, along with blog posts from Joe Gregorio). On the face of it, I disagree that it won't scale. I would like to have a scenario. I guess generators could be used to make RESTful web services as easy as GWT-RPC (I didn't investigate yet, as our server-side language is... JavaScript!)- Hide quoted text - GWT RPC has to be considered as part of the optional COD variant of REST. In a nutshell, interactions between a GWT client and server are private interactions between components which are not expected to independently co-evolve. The scaleability is one level up, where the GWT host HTML file appears as a regular Web resource. Thanks for your answers. I think the way GWT has advanced AJAX, these REST questions need serious reconsideration.

Severe performance problem after upgrading to GWT 1.5.2 (final)
Hi, I've just upgraded one of my projects from 1.4.60 to 1.5.2, and everything went very smoothly, but... when my application tries to fetch a large number of objects from the server (via RPC, returns HashMapInteger,xxx, about 6000 entries) it takes a very very long time! Before the upgrade this was very fast (at least in Firefox and Chrome, not in IE). Strangely, while waiting for the RPC call to return there is NO cpu activity... For me this seems related to some deep changes in the serialization code (taking a guess here), before the upgrade trying to fetch so many records from the server would crash IE with 'JavaScript SyntaxError exception: Out of memory', while now it works (good!) but is very slow in all browsers (bad!).

Re: append new data in Livegrid
Thanks for your responses... I kind of get the thing working. Here is my logic: On the server-side, I periodically query the database for new records and append them to my Object[][] data. Whenever the client click Refresh button for example, the server-side will send the data[][] back in JSON format. There is a problem with this approach, however, as the Object[][] data array will grow very large over time and consequently, the JSON data as well. That brings up another set of questions :-) 1. On the server-side I would like to store only new records in data[] [], and let the client keep track of past records. Server will only send new data since the last client refresh. How do I append new data into BufferedStore and/or JSONReader and refresh the livegrid? 2. Instead of waiting for the user to click Refresh button, I would like to auto refresh the grid periodically -- How can I achieve that? What functions does the Refresh button invoke?

Could it be that you have some sort of proxy setup to get to the Internet? If so, the hosted mode browser probably isn't aware of it.

Re: Using EasyMock in GWT Test Cases
So going by this theory does it do the conversion of junit libraries since they are needed. ?. Since mocking is such an essential part of unit testing could some one suggest how one should include it in GWT. My GWT Classes incorporate both pure java classes and overlays on existing javascript libraries. GWT and its associated toos is really a lot of magic and a beautiful piece of engineering. I wish they would publish more articles, documents etc on the internals of GWT so others could learn from experiences of these great developers.

Trouble loading common files in Eclipse
This is probably trivally easy, but I find the documentation on modules a little sparse so hopefully someone will help me out. I have a project under Eclipse that I have split into a client side project and a server side project. I do this so that I can run the server under Tomcat 6 rather than the built-in Tomcat. Both projects share common files, which I initially just put into the client project and included the client project in the server's class path. Unfortunately, I get problems with versions of things like the Bootstrap and Servlet classes between the Tomcat 6 I'm running and the native version in GWT. So, I pulled my common files out into yet a third project and am trying to include that project into my client project, but I can't figure out how to get the GWT compiler to find those common files. I have the project in my class path. I have the source files called out in my module XML file: source path=com/blah/v4/common/client. I even tried making the common files into its own module and inheriting it. But I can't get the compiler to find them. I am running on Windows so I am not sure what the right syntax would be for absolute-pathing the files (though I have a tried a couple things). There has to be some clearer information on the right way to do this. Can someone please point me in the right direction?

Real world UI development and GWT
I'm trying to choose an appropriate framework for a mid-large scale web app. I've built apps using JS and javascript libraries, such as Dojo and Prototype, but am looking for a more comprehensive approach. I like what I see in GWT, but for the most part I don't want to do large scale UI generation in GWT - the real world approach has been: - graphic designer lays out HTML pages w/ css - development takes pages, tweaks IDs and develops code to access those elements (via IDs) for data injection. With an existing J2EE architecture from which to retrieve data, GWT- RPC is an obvious choice. But I don't want to get into heavy developing of UI Layouts - I prefer to access object via RootPanel.get(MYID) then add components into a page already nicely laid out by my designer. The main pages are spreadsheet like tables, so my thought is to use GWT-EXT to generate and populate these tables with data. But these initially empty tables exist within an existing HTML page layout given to me. IOW, the pages are generally semi-static but component contents are dynamically loaded. Bottom line I don't want to get back into Swing-like coding and layout tweaking, but rather focus on M and C of the MVC paradigm. Do you think GWT is a good solution for this basic paradigm of web page development? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Getting User Input from Input Field
I tried elem.getAttribute(value). It unfortunately, didn't change the behavior. As for using a text box, this example is a dumbed down version of what I'm doing. The real application is integrating GWT as part of other (non-GWT) JavaScripts. The other JavaScripts are inserting data into an input field. I would like to read those values from the GWT part of the application. If there is a better way, I'm open to suggestions. I merely added the HTML element to better simulate the situation I'm in. I guess the sample code isn't a good example. I don't have a direct access to the Element object. I would have to get element by ID (the commented out lines in my example). I guess, the real question is how do I get non-GWT javascripts to talk to GWT? I'm also curious to why it works in IE and hosted mode but not other browsers. I thought GWT was (thankfully) suppose to take care of browser differences.

Different request but get same image issue.
I use GWT to build a pictures gallery (3 by 3) which get the images
from a server. Each image is unique.
The client will request from the server and a java servlet will
generate the image.
The problem is when the pictures gallery displays the images,
sometimes it would shows same image although the request to the server
is different.
For example:
Image #1 : image.setUrl(http://www.domain.com/servlet?
args=image1);
Image #2 : image.setUrl(http://www.domain.com/servlet?args=image2;);
But it's would shows same image for both requests instead of showing
different images. Usually it's happens when both images sit side by
side.
When I refresh the browser (F5), it will display properly which is
it's display two different images (one of the image will display
correctly).
For your information, on client side I use iteration to create the
Image object and set the Url; such as:
for(int i=0, i9; i++){
Image image = new Image();
image.setUrl(someUrl+args);
}
Anyone know what the cause of this problem and how to solve it?

Re: GWT Projects in Eclipse 3.4.0
Marcus, I'm not sure if you have resolved this or not, but this happened to me when I was integrating GWT into a JBoss application. I had to right- click on the the src folder and do a Refresh. Just hitting F5 wasn't reloading everything. As an alternative (if this doesn't work), you could always create a linked project folder to the public folder in your workspace (New Folder Advanced Check Link to folder in the file system Browse...).

The articles are quite old by now. You can also search the history of this list and the history of the Google-Web-Toolkit-Contributors list for discussions on generators or reflection because the answer to just about every reflection question is use a generator. Finally, the GWT source includes several generator implementations--there's at least the RPC generator, the i18n generator, and probably several others.

Re: GWT using maps api problems
This is the first time I've heard of the Fusion product. From looking at the First Base Solutions website, it looks different from the Google Maps API that gwt-google-apis wraps.

Re: GWT Compilation Time
That blog post does a bunch of stuff in step 3 that I definitely would not recommend. Building your own version of GWT for that is not necessary. You can set those properties in your own module and it will redefine them. Or if you really need to, you can just put your own UserAgent.gwt.xml in the CLASSPATH in front of the gwt libraries and that works too, you don't need to rebuild GWT for that.

Re: GWT and Real World UI Development
To be honest, GWT is not that great at the team designer vs developer separation at the moment. There are ways to mitigate that (tools like Instantiations designer), and approaches that help (clear rules for css names for widgets/elements and then a designer who can really just work with the CSS to tweak things - but still the developer has to have some idea of how this works too), but it's not as clean as more traditional web app work, in my experience. Declarative UI though is on the way, and that will really help in this area: http://code.google.com/p/google-web-toolkit-incubator/wiki/DeclarativeUi. And, don't get me wrong here, even though I think this is not a strong suit of GWT at the moment, I think all of the other advantages are huge and I would still advocate using it - and have used it myself on a few medium/large projects, and a bunch of small ones (advantages like working with Java and having an IDE, static types and static analysis tools, unit tests, a single code base that works for all the major browsers . . . most of the time, and more). On Sep 16, 8:33 pm, philserve [EMAIL PROTECTED] wrote: I'm trying to choose an appropriate framework for a mid-large scale web app. I've built apps using JS and javascript libraries, such as Dojo and Prototype, but am looking for a more comprehensive approach. I like what I see in GWT, but for the most part I don't want to do large scale UI generation in GWT - the real world approach has been: - graphic designer lays out HTML pages w/ css - development takes pages, tweaks IDs and develops code to access those elements (via IDs) for data injection. With an existing J2EE architecture from which to retrieve data, GWT- RPC is an obvious choice. But I don't want to get into heavy developing of UI Layouts - I prefer to access object via RootPanel.get(MYID) then add components into a page already nicely laid out by my designer. The main pages are spreadsheet like tables, so my thought is to use GWT-EXT to generate and populate these tables with data. But these initially empty tables exist within an existing HTML page layout given to me. IOW, the pages are generally semi-static but component contents are dynamically loaded. Bottom line I don't want to get back into Swing-like coding and layout tweaking, but rather focus on M and C of the MVC paradigm. Do you think GWT is a good solution for this basic paradigm of web page development? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Severe performance problem after upgrading to GWT 1.5.2 (final)
not sure, but maybe there are some datatype penalty issues (long vs double etc). Did you profile your server side code?

Before the upgrade this was very fast (at least in Firefox and Chrome, not in IE). Strangely, while waiting for the RPC call to return there is NO cpu activity... For me this seems related to some deep changes in the serialization code (taking a guess here), before the upgrade trying to fetch so many records from the server would crash IE with 'JavaScript SyntaxError exception: Out of memory', while now it works (good!) but is very slow in all browsers (bad!).

Re: GWT's HTTPS design consideration and guideline?
yes, there are differences. Testing: Use -noserver. Google for it on this newsgroup for more info on how that works. SSL has three notable differences. These aren't the only ones, but probably the biggest surprises: CACHING: Web browsers were designed to cope with idiot web server maintainers. This was a phenomenally stupid move, as you should never underestimate the ingenuity of idiots, but, alas, we're stuck with this bass ackwards principle, and it screws you over when you use SSL. The first culprit is caching. In SSL mode, you can push 'please cache me' all you want, but in general web browsers will ignore you. You should still try, but, take it with a grain of salt, and make sure you're set up to handle quite a bit of bandwidth. I've got an item on my todo list I should really get to, and that's to create a table to list which HTTP headers, if any, will make a browser cache stuff in SSL mode. REFERRAL: Web browsers will not send a referrer header if you link from https to http. The thinking here is that in the olden days, not everyone had cookies enabled, so you faked it by storing the session ID in the url itself, and you inspected the URL instead of the cookie to figure out a user's session id. This was not just a flagrant abuse of the whole concept of HTTP, but also a gaping security hole, because browsers tend to litter URLs all over the place. In caches, history data, and, yes, referral links. Instead of recognizing that this behaviour is simply security broken and spreading the word to stop doing it, the SSL standard edicts that HTTPS pages should not be sent as referrer to non-http pages, evidently in some sort of screwed up belief that sites running on https are more trustworthy in case an https page did use the session id in the URL trick to get around disabled cookies. D'ooh. You can fix it by bouncing all links through plain http on your own server, letting it redirect. But that's an ugly hack, and I won't get into how to set that up in this post. MIXED MODE WARNING: IE is especially sucky at this. You're free to swap the document domain between http and https all day long,but load one non-https piece of content in an https loaded page and the user gets an awkwardly huge warning dialog that no one understands and make them run for the hills. In practice there's rather little security leakage in e.g. loading user avatar images off of non-https, but, again, the SSL standard thinks it knows better than you and stubbornly gets in your way. Not to mention the rather stark difference between proctecting yourself against eavedroppers and the harder task of keeping out man-in-the-middle attacks. SSL acts as if the first (just protect against eavesdroppers) is somehow beneath it. Argh. No solution to this one as far as I know. Load it all over SSL. Yet another reason why so many people use SSL only for login and then move out, to avoid these issues, not because it costs a little more CPU. FORK OUT SOME DOUGH: https sans a signed certificate is like a party without booze. What's the point? Unfortunately, in order to be considered signed on all major browsers, you need to shell out some cash, about 100 dollars for a single domain, 500 for all subdomains to one domain. This step isn't optional - the security dialog that pops up when your SSL cert isn't signed properly is a lot scarier for a user than no https at all, and for once for good reason, as there's no way to verify that you're really talking to whatever's in your location bar without it. Just don't give your money to those bastards at verisign. They'll kill the internet if it were up to those freedom haters. That means, avoid verisign, thawte, and GeoTrust. Consider Comodo, or Entrust. I strongly urge you to heed this warning; verisign's control of the universally accepted root cert market is around 80% nowadays. If they control all of it, expect your yearly costs (oh, yeah, that 100 bucks is a yearly payment, sorry) to go sky high. It's in all of our best interests if that does not come to pass.

Re: Question on parsing JSON string
Yah, my new JSON library will. But it's not ready quite yet. Well, the
reading bit's ready - still working on writing. If you want to beta
test it, mail me. The core contributors are more or less agreed that
the current offering is a bit weak so you might see it as part of the
core GWT library in GWT 1.6. You're in luck - because of my attempt to
get the library introduced as part of GWT proper it has even more unit
tests than I'd usually write, so it should be pretty robust.

Hello Miguel,
This patch adds an overload to LocalSearch.setCenterPoint() to accept a
JavaScriptObject parameter. It can be either a raw GLatLng or GMap2 object,
or it can be a LatLng object from the gwt-maps API (which is just a Java
overlay type for GLatLng). I tested this manually by creating a small demo
project.

I wasn't including the source files. Disregard. Release should be soon. On Sep 17, 3:38 pm, chris.ruffalo [EMAIL PROTECTED] wrote: One final bit of help. I'm having problems building a jar that will work with the modules to compile under a normal project. If I export the jar with Eclipse everything works fine (add directory entries and all that) and the compile and shell modes work. If I use an ant task to build the jar then it will not work with the compiled mode or the shell mode. I've never been able to have ant (1.7.1) do this in the past either, on other projects.

If the PrintWriter is null, just return the name of the implementation class that you were tryping to create. It works this way because you may want to generate different code for different user.agent values or along some other deferred-binding axis. In this case, you would name the implementation classes differently. -- Bob Vawter Google Web Toolkit Team --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
