Re: Creating new methods for Async class
I did this and it work perfectly
QueueResult processActions(String user,QueueAction actionQueue)
when I implemented it I had a lot of problem due to serializable
interface. and it is very hard to catch.

Your return value is an ArrayList, not a String - so much about
compatibility of types. However I am not sure if you can actually
return an ArrayList (due to the requirement to have implemented the

work but would require you to turn your return value into a static
String array.

Re: how to send variables in form panel
Hey abhiram,
I still have a problem in server side,, can you tell me how to catch
variable from client.
Let say I have a textbox in client.
Textbox txtComment = new Textbox;
txtComment.setName(txtComment);
txtComment .setText(hello);
in server side:
I've tried:
String varXXX = (String) request.getParameter(txtComment);
but that's not working. :(
and I've also tried like this :
try {
List items = upload.parseRequest(request);
Iterator it = items.iterator();
while (it.hasNext()) {
FileItem item = (FileItem) it.next();
if (item.isFormField()) {
String name = item.getFieldName();
if (name.equals(txtComment)) {
ret = item.getString();
}
return ret;
}
}
} catch (FileUploadException e) {
return null;
}
but still null return.
can you tell me how to catch it.
regards

Hey Yoez,
Not sure if it helps. But i have a workaround solution for this. Make it a
two-step process. First use a RemoteServiceServlet to pass across your
variables to the server side and then save these values into some variables
on the server side.
Then you can use a HTTPServlet to pass across your file contents to the
server side. Now you have the file as well as the variables.
HTH,

Re: programmatically set focus to TabBar tab

TabBar.Tab does not implement Focusable, and neither does TabBar, and this is confusing. I expect to be able to call tabBar.getTab(n).focus () but no deal.

Re: GWT best Practices - JS Library Wrappers Overlay Types
Version 2.0.1 will be available probably later this month. The IE bug
is gone, which is nice since it makes it possible to use the
AjaxLoader module, which eliminates the need for a script tag and
simplifies loading packages individually.
The samples for 2.0.1 dynamically load packages as needed:
http://gwt-gdata.appspot.com/v2.0.1/HelloGData.html
By the way, even though i've used static initializers for constants,
i'm not seeing any initialization cost. I think maybe GWT is inlining
the initializers, since the initializers are native methods on overlay
types.

I may not be able to correct this IE bug, and it may not be desirable
either since it isn't a good idea to have the GWT version introduce
hacks onto the JS library in order to fix a bug - stuff like this is
better off being corrected in the JS version directly. I'll add this
as a defect and deal with it later, the workaround being to use a
script reference to load the API.
I'm starting to think about how to detach the GWT library from the JS
api in the future. Here's what i'm seeing, in the JS API all GData
operations (POST, PUT, DELETE) are sent as POST commands. A POST
variable called HTTP-Method-Override can be used to specify the actual
operation. Cross-domain POSTS aren't a problem, we can just create and
submit a hidden form using some JavaScript.
Since GData supports retrieving data in JSON format, we can use a
JSONP approach to do cross domain reads - this is what the current JS
API does.
This means that in order to detach the GWT version from the JS
libraries we have to:
1. identify the Atom schema for each data type, there are a few
hundred classes.
2. provide a base implementation that can perform cross-domain POSTS
and JSONP reads.
I think #1 can be automated and #2 is sensitive but small.
The end result will be a more GWT-optimizable API which can then grow
at its own pace. The samples and unit tests wouldn't change
significantly, if at all. We can still use overlay types to wrap
around the JSON objects returned from GData. I've taken a closer look
at the GData Java library and i don't think that the GWT and Java APIs
will ever match because the GWT version will need to be callback-based
whereas Java doesn't have this limitation.
Anyway, just some thoughts.

There are some quirks which are making it difficult to narrow down the
reason why AuthSub fails in IE. So far i know it only happens when
google.load is used with a callback, even when google.load is called
while the page is being loaded.
So something like the following:
body
script
google.load(gdata, 1.10, myCallback);
/script
input type=button value=login onclick=google.accounts.user.login
('scope-here') /
/body
Will always see the following behavior:
1. User clicks to login.
2. User is redirect to authorization page and clicks to authorize.
3. User is redirected back to the original page, with a token appended
in the URL.
4. Page doesn't consume the token in the URL (the correct behavior is
for the page to place the token in a cookie and remove the token from
the url).
5. User clicks to login again.
6. User gets redirected to authorization page again, and steps 3-6 are
repeated an arbitrary number of times.
7. If, after reaching the authorization page a second time, the user
clicks the browser's back button, causing the browser to go back to
the page that contains the token in the url, the token is successfully
consumed and the user is successfully logged in. Go figure.
Why backing into the page causes GData to successfully consume the
token i have no idea - especially since refreshing the page at step 4
has no effect.
My guess is that when backing into the page IE will use a cached
version of the GData script, which is processed immediately and may
make the difference.

Re: Targettting Rhino with GWT compiler
On 20 oct, 15:53, Attila Szegedi szege...@gmail.com wrote: Hi all, I really like the development model of GWT - using Java for development, with all its type robustness and refactoring friendliness. I have a rather large JS system that badly needs rewriting after five years of incremental spontaneous evolution and I consider using the GWT compiler to redo it. The gotcha though is that this is not a browser-run front-end application, rather it is a server side JavaScript system, using Mozilla Rhino on the JVM as its JS runtime. Am I correct in thinking that I could still use GWT for development - I could have my system written in Java, and then compiled to JS by GWT compiler and deployed into our Rhino-based server-side runtime system. (Before you ask, no, we can't run Java on the server side, we have a massively parallel system that absolutely needs continuations to retain its scalability). So, GWT compiler would have no trouble emitting code for a non-browser environment? AFAICT, GWT emits valid ECMAScript, so it should run in Rhino without problem. You'd have to make a special Linker though (the thing that generates the *.nocache.js and chooses how to output the compiled JS in either md5.cache.html or md5.cache.js), as GWT's built-in linkers expect a browser runtime. Also, would it be possible to have a Rhino runtime as the debugger target instead of a browser? With OOPHM (shipping in GWT 2.0), it shouldn't be a problem (again, you'd have to write a Rhino-based OOPHM client). I actually believe the HtmlUnit-based OOPHM client (used for unit tests) runs Rhino (and simulates a browser runtime). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT and MySQL Connection
Hey, I am trying to create a voting system I've got a MySQL DB already
up (using WAMP) and I'm using Eclipse Galileo with GWT. I have looked
everywhere on how to make this connection and now I am sure I connect
to the DB at least, however I am unsure regarding if I actually
retrieve anything from it and I can't print anything because it throws
me an exception. This is the method that should access the DB:
public User authenticateUser(String user1, String pass) {
User user = null;
try {
PreparedStatement ps = conn.prepareStatement(
SELECT user, pass FROM usuarios WHERE user =
\ + user1 +
\ AND +
pass = \ + pass + \
);
ResultSet result = ps.executeQuery();
while (result.next()) {
user = new User(result.getString(2),
result.getString(3));
System.out.println(user.getUser().toString());
System.out.println(toy aqui);
}
result.close();
ps.close();
} catch (SQLException sqle) {
System.err.println(Fail!! = +
sqle.getStackTrace());
}
return user;
}
conn is a Connection already made here:
public MySQLConnection() {
try {
Class.forName(com.mysql.jdbc.Driver).newInstance();
conn = DriverManager.getConnection(url, user,
pass);
} catch (Exception e) {
System.err.println(Fail en la Conexion = +
e.getStackTrace
());
}
}
after this, I use this method which should allow me to access stuff
from the newly created object:
private class AuthenticationHandlerT implements AsyncCallbackUser
{
public void onFailure(Throwable ex) {
label.setText(Fail);
System.out.println(ex.getStackTrace());
}
public void onSuccess(User result) {
try {
label.setText(Success);// + Pass::
+ result.getPass
().toString()
}catch(Exception e) {
System.err.println(Fail! = +
e.getStackTrace());
}
}
}
The thing is, it doesn't matter if I introduce wrong values for the
Query to be made with, (user1 and pass) I get success or fail
everytime depending on which I started with. That is, if I tried once
and failed, then everytime after I will get Fail and if I try and
get the write data in I will get Success everytime.
I don't know why this happens and I am unsure I am performing the
query the way it should be done.
The only thing I'm 100% sure of is that the DB connection is made, and
that if I try to print result.getUser(); in the last method I placed
here, I get an exception.
What am I missing or doing incorrectly?

Re: Creating new methods for Async class
(1) The problem with the OP's code was that he had the getClients() method in the async class take an AsyncCallbackString but the non-async interface returned an ArrayListString. If you want to return an ArrayList of strings, then the callback should have been AsyncCallbackArrayListString (2) ArrayListString is better than ListString in GWT RPC interfaces because if you use ListString, then the GWT compiler must search for every implementation of List and spend time looking at whether it's used/making the serialization code for it. At the very least, compilation is faster if you stick to the most specific declaration you can. It may also generate less javascript. Paul Trevis wrote: Not to complicate matters but using ArrayList instead od List supposed to be better in gwt? I could have sworn that ray ryan alluded to this in his presentation.

candle stick charts
Seems to be no good way to create candlestick charts (stock charts) with GWT. I noticed the chart API provides the option but does not integrate with GWT (although I think I saw a third party library, ill look more into that today). The visualization API does not allow it, at least as far as I can tell. I can create the chart I want with the gwt-canvas package but it does not appear that I can add text. So there are ways to do it but none that I can see are complete. Anyone have any experience with this?

Re: Hosted mode hanging 4 out of 10times
Just thought it might be worth mentioning that I have been having this
problem for about 4 weeks now... I was hoping it might be dealt with
in the lastest updates, but its still there!
Im using GWT with GAE functionality, my app is built up from the
original stockwatcher application.
I actually have periods of time when I get this problem over and over
and over again, but usually I find that it eventually sorts itself out
without me doing anything, I just keep trying to restart hosted mode,
and eventually it kicks in by going to the correct url
There are suggestions around (not sure if they are also in here) that
clearing the IE cache can fix this problem, and that worked for me for
a little while, but then it didnt work anymore, and after experiencing
the issue so many times, i now know that its just a waiting game.
However, I also find that closing eclipse down and reopening it seems
to clear the problem too, but then again that just might be due to the
time period it takes to shut down and restart (the ubiquitous have
you tried rebooting solution)
Cheers,
J

Re: why does GWT Showcase continually re-request CSS image under IE6
I figured out the issue finally. IE6 will cache all images reference on a given web page BUT! - if the image has a the same name as another image (even if in different directories); it will forgot the previous cache image and load it again from the server. Thus, in IE6: /image/foo/n.gif /image/bar/n.gif will effectively be considered the same thing! if you have a lot of rounded buttons using a common naming convention look out! the way around it is to make sure all file names are unique (even in they are spread across different directories) On Oct 9, 4:33 am, Thomas Broyer t.bro...@gmail.com wrote: On 8 oct, 21:58, jmcmd ru...@mdecisions.com wrote: UnderIE6my application grinds to a halt because the GWT appears (i might be wrong) to somehow forceIE6to re-load all my CSS images any time their is a UI event where I make a Widget visible - even if that image is already visible on the screen.

I have tried every server-side setting for the response headers and it did not change a thing.

My app (and the showcase app) work perfectly normal under IE7/IE8,FF, Safari so this only appears to beIE6 related. I can't be the only one who observed this issue - perhaps I'm missing something obvious, but any help or guidance is greatly appreciated. My app is more or less un-usable inIE6because I have about 80 css images and havingIE6make 80 request every time I make a various visible makes for a very sluggish experience. In great need of help Is this with an ImageBundle or an Image on its own? If you're not using an ImageBundle, are you clipping the Image with setVisibleRect or setUrlAndVisibleRect? In the case of an ImageBundle or clipped Image, are you using HTTPS? if so, make sure IE isn't configured to not save encrypted pages to disk (that's because the clipping is done using the AlphaImageLoader ActiveX) You say you've tried every server-side setting, have you set the Expires and/or Cache-Control:max-age to far future for the image files? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Servlet and GWT
Hello friends, I am new to GWT. Recently i learnt servlet and JSP. My problem is i want to have a nice dynamic front end.When user performs some action, it should send request to server. Server should do some data manipulation on the basis of data sent from client and send back the response. I am not getting the actual pipe line. In which of the following GWT/ SERVLET/JSP language i should write Front end and server side codes. From Some source i knew that front end we can make in GWT and servlet side scripting in JSP/Servlet. If this is true then how can we link these...can anyone suggest . I use Eclipse.

Google Eclipse Plugin issue w/ GWT 1.7.1 and hosted mode
I am posting here before I post an issue to the tracker to see if anyone has run across it. I am using Eclipse 3.4.2, but I doubt it's specific to an Eclipse version. Basically, if you have two unrelated Web Application projects in the same workspace that have the same HTML filename then running as a Web Application will use the previously run one instead of the project you right clicked on. To replicate: 1. Create a Web Application project named 'testapp1' 2. Create a Web Application project named 'testapp2' 3. Run each (one at a time of course) to make sure they run 4. Rename testapp1/war/testapp1.html to index.html, then run it as a Web Application 5. Rename testapp2/war/testapp2.html to index.html, then run it as a Web Application It will attempt to run w/ testapp1's classpath and server resources which cause a 404. Can anyone else replicate this issue before I open a bug? Has anyone seen or reported this issue before?

migrating to GWT and including custom data to module.nocache.js
My company's product is accessed via a javascript file that is in our customer's host page. They're page just includes a script tag that links to the javascript file. We have many customers, and we create unique javascript files for each by generating custom data and the Javascript file. We happen to use a JSP file to inject all the customer specific data and the common JS business logic into a single JavaScript file: customer-specific data + common JavaScript = unique JavaScript for each customer Is it possible to compile in specific custom data (JSON data) into the module.nocache.js file? Then I would generate one module.nocache.js file for each customer and then reuse all the late binding files. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

any way to return image through rpc?
I'm looking for a way to make a gwt service call, have the server create an image, and then send the image bytes back down to the browser. I can do this with a standard servlet call, but my query is getting unruly and I'd like to take advantage of gwt's serialization and build my request that way. The only other option is to have the gwt service return a url (string) to an image, but this would require that I actually save the image to disk, which I don't want to do.

Re: any way to return image through rpc?
You can send bytes back to the client as an RPC response (it's just an HTTP request, after all) but the problem is what to do with the bytes once you have them. If you're willing to restrict yourself to browsers that support data:// URLs, you can send the image back as a data:// URL and just drop the result into an img tag. That approach excludes many (all?) versions of IE. As far as I know, the only IE that _might_ support data:// URLs is IE8. To be fully-compatible, you need to forge ahead with your existing approach or, as you say, generate a URL via RPC and make the generated URL resolve to the desired image. If you want to fool around with the RPC infrastructure, you could possibly use a GWT-RPC request payload as the query parameter in a standard request, if you think such a representation would be more compact/useful than the representation you're currently using. On the server side, you could then use the RPC class (is that still in use?) to deserialize the parameters and drive the image request. Might be more trouble than it's worth, though.

There is no WYSIWYG editor that I know of. Because UIBinder is so new (it's only been in the public source control for about two months), I wouldn't expect to see such an editor for several months at a minimum. If you see one it's likely to come from the guys who make MyEclipse (google it).

[gwt-contrib] Re: Server side I18N
I don't think that you guys are seeing the whole picture. By making
the string replacements part of the compiled code you actually bind
the internationalization into the code. Trust me, when a web
application is supporting 20+ languages, the translations will never
be absolutely flawless, and the JIT string replacements/formatting
that you are complaining about is a very small factor when dealing
with large applications. Compare the time taken for dynamically
creating, say 200 DIV elements within a DOM tree, with time taken for
replacing 2000 internationalized strings using JIT and you'll find
out that this is absolutely NO extra time spent and just a VERY small
overhead comparing to a web application with the strings compiled into
the nocache-files.
In a perfect world, the texts would be flawless from project startup,
but when creating one major application per month to different

The problem is that it is more than just that. Take this for example:
- Folder name: {0} File name: {1} in English
- xxx {1} yyz {0} xkx in some other locale
The code generated is different and there is no piece of text in the
English output that can be changed to produce the other locale, and that is
because we actually parse the format string at compile time.
Out of curiosity, could you post a sample of the generated code?
If we instead just substituted those strings, you would have to have all
the format parsing code in the compiled output, which will be essentially
String.format. In addition, right now we just generate calls to
NumberFormat/DateTimeFormat for actual formatting and they parse their
pattern at runtime, but I have work in progress to move the parsing of the
pattern to compile time.
Beyond this, there are things like:
@DefaultStringValue(lb)
String weightUnit();
and code that does if (kg.equals(constants.weightUnit())) { weightFactor
= 2.2; } and then that factor would get inlined all over the codebase by the
compiler where it is used. [Note, I don't recommend this pattern, but I
have seen it used].
Ick. There are so many other ways to accomplish that, I don't see it as a
valid use case for something that would likely be opt in.
So, it isn't as simple as doing string substitution on the compiled output.
Even discounting plural forms (and frankly, I think any properly localized
app needs to use them), there are other cases where it would be rather
expensive to be able to do string substitutions on the compiled output.
One possible approach would be extending the runtime locales approach
(similar to Bob's soft permutations) to cover Messages/Constants. That way
the code is optimized for each one, but there is basically a switch for the
proper implementation for the current locale, and that choice is made once.
You still lose inlining and you are downloading code you will never
execute, but perhaps there could be some runAsync integration to reduce the
download penalty.

Thoka, does your code involve changes to GWT proper? If not (or if so, for that matter), would you be willing to create a new Google Code site for it?

No, the code does not involve changes to the standard library. The only thing you have to do is to replace the localization module to another in the gwt.xml file. It is very simple and contains about 5 simple classes. The only thing you have to do manually is to link lang.js to a servlet in web.xml. We started creating this module for about 3 month ago, and we still need to test it more thorough, which is why I posted this here to get more people involved for comments, features and optimizations.

[gwt-contrib] Re: Server side I18N
Thoka, I hope previous replies didn't come across as a debate as to whether the use cases you describe are valuable or not; clearly they are. The point is just that we want to identify exactly what the pros/cons of each world view are to decide, among other things, if there is one right answer versus just acknolwedging that there should be multiple libraries, each with different tradeoffs. In this case, it seems quite likely to be the latter. So, as Ray suggests, if you'd be willing to make your library available, you could start evangelizing it to other GWT users and if over time a consensus emerges in favor of that approach, it would be much easier to justify trying to roll that functionality into GWT proper.

[gwt-contrib] Re: Server side I18N
It sounds like an alternative might be to have the compiler to spit
out properties files full of key value pairs with one per locale.
Naturally the compile would output shortened keys etc and record a
mapping file. A tool would be made available to update just these text
resources and the initial bootsrap code so it now picks up the newly
updated files. The exiting use of cache files as much as possible
would remain, but there would be less permuTation generated files.

out that this is absolutely NO extra time spent and just a VERY small
overhead comparing to a web application with the strings compiled into
the nocache-files.
In a perfect world, the texts would be flawless from project startup,

[gwt-contrib] Re: Server side I18N
Perhaps the compiler just recompile Message etc type classes and have them in a separated *.js file. The problem with that is of course what about references to helper methods and the like that live in the main module. A mapping file would need to record names of said methods. There might also probably need to be a mechanism to avoid inlining a method in main that might need to be called from a messages module. I know this has been discussed before when others want the ability to add plugins to an application without recompiling.

I don't know if this solves the right problem, and maybe it would be
more trouble than it's worth, but I think you could straddle the
middle here.
Take your earlier example:
* Folder name: {0} File name: {1} in English
* xxx {1} yyz {0} xkx in some other locale
Presumably that compiles down (in English) to something like this:
Folder name: + valueOfZero + File name: + valueOfOne
and then the optimizer has its way and things get inlined, propagated,
or whatever. What if you just used variables instead and populated
the variables via some external mechanism. Something like this:
$locConst0 + valueOfZero + $locConst1 + valueOfOne
The compiler could generate the names folderNameConst and
fileNameConst in some deterministic way so that you could take the
original list of properties
some.developer.chosen.name=Folder name: {0} File name: {1}
and map it to this
$locConst0=Folder name:
$locConst1= File name:
in an automated way. If the automated way is a tool you could run
separately from a full compile, Thomas could rig it into his
internationalizing servlet such that the user updates the original
properties file, and then the tool regenerates the GWT-optimized
version. Perhaps the result wouldn't be as thoroughly optimized as
the current system (no way to detect that $locConst0 and $locConst1
are the same, for example), but it would be more optimized than
parsing message format strings at run time and it would (I think)
solve Thomas' problem.
Thoughts?
