Re: Compiling a single Java class to a plain JavaScript file
rapodaca: Reread my original post. Even if you turn the mangling off, the name would then become: com.mypackage.MyClass::hello() Instead of what you probably want: hello Due to the parens, you'd need to call it like so: window.[com.mypackage.MyClass::hello()](); instead of like so: hello(); 'unwieldly' doesn't really cover the ridiculousness of working with this. 'utterly ridiculous' is a bit closer to the mark. The above is WITHOUT the mangling. -style pretty is a bit less unwieldy, but, really, you'd have to get in there and write your own identifier formatter that does saner things, and that's just one thing that comes to mind. I'm fairly sure its not going to be the only hurdle.

Take your example just to illustrate the problem here: How would that even translate to javascript? Javascript doesn't have classes. It has prototype based inheritance. Here are your fundamental problems: Reinier, thanks for the info. Actually, a class isn't the thing I'm after. What I really want to create are objects. So I thought it could translate something like this: html ... script src=hello.js/script ... script type=text/javascript var hello = new Hello(); hello.talk // returns hello /script ... /html What am I missing? 1. Javascript's namespacing and object model is so different, that GWT internally generates completely different and unwieldy names for objects and classes. These names are then mangled to unrecognizable shortcodes to reduce the size of the output JS. So, your public void hello method is either going to be called: com.mypackage.Hello::talk () (yes, including closing parentheses to indicate that this version takes no parameters; unlike javascript, in java two methods with the same name but different parameter lists are completely separate, in javascript you can't do that), or it's going to be called something small and effectively random, so something like 'xYq' or some such. There's no code to pick a sane name for interaction, so nothing there that would even think to generate just a function called hello. I thought it was possible to turn off the mangling by setting compiler flags. I've also read about JSNI in this context. Wouldn't one or both of these help? 2. There's a base set of functions that all GWT projects start out with. The GWT compiler assumes this basis is there. That wouldn't be a problem for me. 3. GWT does something called platform targeting. That's why it generates a number of JS files - one for each target platform. Out of the box, there are already multiple platforms (1 for each major supported browser, so there's an Opera, an IE, a Gecko, and a Webkit). I'm not entirely sure but I believe the base, talked about in #2, is already written specifically for each target browser platform. Also not a problem. If you are in the market to build such a tool, The GWT sources are a great place to start, but unless you're willing to dig in for a few weeks and do a lot of dev work, I don't think GWT can do what you want. Sounds way above my head. I have to say, though - I'm very surprised this hasn't been done already. It seems like such an obvious use of GWT. NB: I'm not an expert on the GWT internals so I might have made a few mistakes, but I'm fairly sure the above is true. #1 is certainly true, and already a big deal for you.

Re: ThreadLocal support
Thanks for your reply. You're right that only one thread is running in a browser. But on the other hand, we could also use ThreadLocal pattern to share some data among multiple different method invocations. In my opinion, ThreadLocal pattern has two basic different usages: 1. Horizontally, it has each thread having its own copy of data 2. Vertically, it also has method invocations in thread sharing data So it will be helpful that GWT supports ThreadLocal pattern for the second usage BR, cai On Jan 10, 2:17 am, Lothar Kimmeringer j...@kimmeringer.de wrote: cobracbh schrieb: Is any possible that GWT's Java2JavaScript could compile ThreadLocal in future ?

Re: can gwt work with javax.swing.* ?
OK, one of the things that you have to wrap your head around is how GWT works. You write GWT using Java, but then the GWT compiler converts this into Javascript HTML. It can only do this to Java that it specifically knows about. Your Swing JLabel component is not something GWT understands and therefore it can't compile it out into Javascript. The strength of GWT is that you develop in Java, but if your code is going to be run in the browser, it has to be Java that is compatible with the GWT Compiler. Hope this helps.

[newbie] Asynchronous calls to get HTTP files
Hello,
I am a newbie with GWT so please bear with me. I would like to write
some code that fetches some HTTP file. I have read the tutorials but
they do not quite answer my question.
private void readFile(String url)
{
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(url));
System.out.println(fetching...);
try
{
Request request = builder.sendRequest(null, new RequestCallback()
{
public void onError(Request request, Throwable exception)
{
// Couldn't connect to server (could be timeout, SOP
violation, etc.)
}
public void onResponseReceived(Request request, Response
response)
{
System.out.println(response received...);
if (200 == response.getStatusCode())
{
PrintOut(response.getText());
}
else
{
// response.getStatusText()
}
}
});
}
catch (RequestException e)
{
System.out.println(exception... + e);
// Couldn't connect to server
}
}
public void PrintOut(String msg)
{
System.out.println(msg);
}
public boolean isInputDataValid()
{
PrintOut(Step 1);
readFile(http://localhost:/com.bruguier.dbquiz/dbquiz.html;);
PrintOut(Step 2);
return true;
}
OK, here's my code. It does something but not quite what I want. The
entry point is the function isInputDataValid(). My problem is that it
prints Step 1, then Step 2, then the content of the HTML page. I
guess the fetching is done in another thread. That is not what I want,
since I would like to return a specific boolean depending on the
content of my page.
I guess I could write the code inside the function PrintOut() but that
is not so good. I am planning to fetch several pages and I would have
to replicate the code several times. I could also use a mutex system,
but that I haven't been able to find. Or maybe there's a ready example
using another approach but I couldn't find it.
Please point me toward the right information. I hope I was clear.
Thanks,
Tony

passing parameters from JSP to GWT
Hi All, I am adding a GWT component in JSP. It should receive several parameters to know how to present data (for example, how many buttons should be, what is the selected value in a drop-down, etc.) The question is how to pass parameters from JSP to GWT. I saw several ways to do it: 1) Go to server, for example using RPC (I prefer not doing this - to save time and minimize number of requests to server) 2) Pass parameters from client side (might be not secure). I saw 2 ways: -define in JSP a GWT Dictionary to contain a map of values that GWT component needs -add parameters on request - in include of GWT noscript.js What is the best practice? thanx --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Compiling multiple modules
On Fri, Jan 9, 2009 at 4:36 PM, jed jedbur...@gmail.com wrote: What am I doing wrong ? Any ideas ? You're not doing anything wrong. For performance reasons, the GWT compiler generates several monolithic scripts (one for each browser, and there are some other axes of specialization). Notice that you only give the compiler one module name and that module includes a bunch of other modules, and those modules may do the same, recursively. You end up with a tree of modules. (Tree is in scare quotes because you might get cycles in the imputed graph, so there's no guarantee that it's actually a tree in the strict sense.) You only give the root of the tree to the compiler and the compiler uses that root to define the scope of the application it's compiling. You'll get one set of output files that each include code for the entire application, specialized along some set of axes. I think you're worried about how to reuse the code in the administrative panel that you've worked hard to separate. The answer is to write another GWT app that also makes reference to that module in its root module.

Any help is welcome.
Best regards.

Re: Asynchronous calls to get HTTP files
It's just working asynchronously. Step 1 gets printed, then the call
to the server is made asynchronously, so the code moves directly to
the next step where Step 2 is printed out. You can't block/sequence
execution of server calls in the way you're thinking in JavaScript
(and therefore not in GWT).
To print Step2 after the file contents, you need to move the request
to print it to the onResponseReceived method of your response handler.

Hello,
I am a newbie with GWT so please bear with me. I would like to write
some code that fetches some HTTP file. I have read the tutorials but
they do not quite answer my question.
private void readFile(String url)
{
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(url));
System.out.println(fetching...);
try
{
Request request = builder.sendRequest(null, new RequestCallback()
{
public void onError(Request request, Throwable exception)
{
// Couldn't connect to server (could be timeout, SOP
violation, etc.)
}
public void onResponseReceived(Request request, Response
response)
{
System.out.println(response received...);
if (200 == response.getStatusCode())
{
PrintOut(response.getText());
}
else
{
// response.getStatusText()
}
}
});}
catch (RequestException e)
{
System.out.println(exception... + e);
// Couldn't connect to server
}
}
public void PrintOut(String msg)
{
System.out.println(msg);
}
public boolean isInputDataValid()
{
PrintOut(Step 1);
readFile(http://localhost:/com.bruguier.dbquiz/dbquiz.html;);
PrintOut(Step 2);
return true;
}
OK, here's my code. It does something but not quite what I want. The
entry point is the function isInputDataValid(). My problem is that it
prints Step 1, then Step 2, then the content of the HTML page. I
guess the fetching is done in another thread. That is not what I want,
since I would like to return a specific boolean depending on the
content of my page.
I guess I could write the code inside the function PrintOut() but that
is not so good. I am planning to fetch several pages and I would have
to replicate the code several times. I could also use a mutex system,
but that I haven't been able to find. Or maybe there's a ready example
using another approach but I couldn't find it.
Please point me toward the right information. I hope I was clear.
Thanks,
Tony

Re: Need opinion on design idea
Thanks. Im thinking I can inspect the cookie in the image.onload event but Ill need to play with it and test across all browsers. Ill post something if it seems workable. On Jan 8, 12:20 pm, todd.sei...@gmail.com todd.sei...@gmail.com wrote: This sounds like a unique and workable answer. If your cookie size does not exceed 4k you should be fine. The only thing I don't know is how the browsers will handle a statically named cookie with asynchronous request. Even though Javascript (GWT) is single threaded the browser is not. Try to queue your requests that use this method. On Jan 7, 7:56 pm, AB abere...@drillinginfo.com wrote: I am thinking about a charting app that will use jfreechart on the server side (I need PDFs and other server side output anyway) and GWT + Canvas on the client so that users can do fancy things like curve fit in the browser. That means that when the client asks the server to render a chart, the client needs to get back a png and also some data (like scaling info, etc). I can of course do 2 rounds trips but I am thinking of combining it into one rt. The idea is that the server response is an image/png but also sets a nonpersistent cookie in the header that encodes the data I need. The gwt app disassembles the cookie value (perhaps it is even json). If the cookie would be too big (unlikely), the cookie value becomes a message to the client that it needs a dedicated rt. Does anyone see a problem with this? Any thoughts are appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to attach a click listener to an existing SPAN element?
Ian, Nothing was wrong in your suggestion, I just cannot modify the DOM structure by adding an element for CSS reasons. My implementation needs to be as unobtrusive as possible.

Re: How to attach a click listener to an existing SPAN element?
Aa, I knew there was something easier than subclassing...
Here is it:
in the Label class:
static
Labelfile:///C:/GWT/doc/javadoc/com/google/gwt/user/client/ui/Label.html
*wrapfile:///C:/GWT/doc/javadoc/com/google/gwt/user/client/ui/Label.html#wrap%28com.google.gwt.dom.client.Element%29
*(Elementfile:///C:/GWT/doc/javadoc/com/google/gwt/dom/client/Element.html
element)
Creates a Label widget that wraps an existing div or span
element.
Example:
somewhere in my HTML file:
span id='colorpicker3'span colorpicker3/span
and in the GWT java code:
Label spanLabel =
Label.wrap(Document.get().getElementById((colorpicker3)));
spanLabel.addClickListener(new ClickListener()
{
public void onClick(com.google.gwt.user.client.ui.Widget
sender)
{
GWT.log(Label spanLabel onClick, null);
};
} );
And I also found the InlineLabel based on a SPAN element.
