.gwt.xml not on your class path
Hi, I have created a GWT RPC application. It runs fine when i deploy it in sepetrate Tomcat and when i run it using .shell command. But when i try to run it using Run->Configuration of eclipse it gives me an error saying that [ERROR] Unable to find 'com/sandeep/transfer/ StringReverse.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Re: exception not caught in a javascript constructor in IE
I finally managed to reproduce this pb outside of gwt. It seems to be
due to the fact the js is loaded inside an iframe (which is the case
of the js generated by gwt).
Here is a simple example to reproduce it.
main.html
function MyObject(){
throw "String thrown";
};
//This function is the workaround to the pb explained in my previous
post
function wrappingMyObjectConstructor(){
try{
new MyObject();
}
catch(e){
throw(e);
}
}
iframe.html
function buggy(){
try{
new parent.window.MyObject();
}
catch(e){
alert(e);
}
}
function notBuggy(){
try{
parent.window.wrappingMyObjectConstructor();
}
catch(e){
alert(e);
}
}
buggy : constructor called directly
not buggy : constructor called via
wrapping function

In Java specify style name for this DockPanel:
DockPanel rootPanel;
rootPanel.addStyleName("rootPanel");
and in css add:
.rootPanel {
margin-left: auto;
margin-right: auto;
}

Re: Newbie Question on GWT/JSON
Whoops, forgot my footnote:
[1] http://www.ietf.org/rfc/rfc4627.txt
I don't know if that makes it official. I believe the official entity
that vets mime types is IANA, but on their site I couldn't quickly get
to an official list of recognized mime types. Still, if Doug Crockford
says the type is application/json, and almost everyone uses that,
that's the standard. That's how the internet works; standards bodies
can wax rhapsodic about whatever they fancy, but if no one does it,
it's not something you should be doing either, regardless of whether
or not its the 'official standard', so, there you have it.
Oh, and martykube: Be careful that your soul doesn't waft out the
window that is giving you that fresh air. As a general rule, if PHP is
a good fit for you, grails, rails, or django are usually an even
better fit.

Benchmarking
Hi all! This topic in the GWT's documentation is very short. I have tried the Benchmarking example with the console's scripts, but it works sometimes, and sometimes it doesn't. Otherwise with the simple GWTTestcase I don't have any problem.

Trouble with setting split position in CSS...
I am trying to set the verticalSplitPane's split position in CSS but
it doesn't seem to be working or maybe i am doing it wrong.
Java:
VerticalSplitPanel tempPanel = new VerticalSplitPanel();
tempPanel.addStyleName("gwt-VerticalSplitPanel");
tempPanel.setTopWidget(VerticalPanelForTopSection);
tempPanel.setBottomWidget(HorizontalPanelForBottomSection);
CSS:
.gwt-VerticalSplitPanel { width: 220px;
height: 270px;
padding-left: 15px;
padding-right: 15px;
pos: 200px; }
i know the CSS gets called from running the program but the "pos:
200px" doesn't get used at all. I tried
gwt-VerticalSplitPanel vsplitter { pos: 200px;} and gwt-
VerticalSplitPanel splitter { pos: 200px;} but didn't work either.
What am i doing wrong here? Thanks!

I'm using the same setup as Ian - GWT + JSON + PHP. This is my first
contact with PHP. After years of working on the bloated stack that is
JEE I've found PHP to be a breath of fresh air. Sure, the aesthetics
are low, but the productivity is high.

Re: GWT project creation indefinetly creates folder recursively

You may have found a bug in GWT. If GWT can catch thrown strings in
the second case but not in the first case, then I think there's a
problem with the exception mapping between the languages. You might
want to file a bug and, if you do, try to include a really good repro
case.

Re: exception not caught in a javascript constructor in IE
Thanks for the really quick answer!!!
I can modify the script I include but I'd rather not. The calls of
"throw" are already wrapped in a function therefore your solution
could be envisaged.
There is another solution that works but I do not trully understand
why. I wrap the call of "new MyObject()" in a function defined in the
foo.js file :
function wrappingMyObjectConstructor() {
try {
return new MyObject();
} catch (e) {
throw e;
}
}
and calling wrappingMyObjectConstructor in JSNI works fine in IE. This
is a hack, it works, but does anyone know how to avoid this or can
explain this?
Thanks

I'm just guessing here because I don't know how GWT maps native
Javascript "exceptions" into Java. I think your problem might be
related to the fact that you're throwing a string, not an Exception
and you're catching an Exception, not a string.
Do you have control over the script you're trying to include? Can you
modify the throw statement to call into a Java method that throws a
"real" exception? Could you factor the throw statement into a helper
function that gets substituted by a JSNI method when the script is
invoked from a GWT app?

exception not caught in a javascript constructor in IE
Hi,
I have a pb related to InternetExplorer and probably GWT (but I'm not
convinced) since I have not managed to reproduce it outside of my gwt
project.
Let foo.js a javascript file containing:
function MyObject(){
throw "String Thrown";
};
In my Module.gwt.xml I add the following line to include the script
Then in any java file of my application, in the click method of a
clickListener for instance, I call the function "createMyObject"
defined as:
public native void createMyObject()/*-{
new $wnd.MyObject();
}-*/;
The call of this function is surrounded by a try/catch block :
try {
createMyObject();
}
catch (Exception e){
Window.alert(e);
}
This works fine in firefox 2 and 3 but not in IE (6 and 7). In IE I
got an "exception rised but not caught" error and therefore no
alert...
What do you think of this problem?
Regards,
Blisseria.

main is a method called from the console (i.e. "server"). You can't
call GWT.create in server-code so whatever you think you can achieve
by initializing DirectionQueryOptions on the server-side it will
never happen.
The question is, what you want to achieve to be able to tell you,
what you might do differently.
BTW: Instead of shouting and the excessive use of exclamation marks,
you might think of a more describing subject in the future.

Re: HELP NEEDED!!!!!
The gwt-maps library is meant to be translated into JavaScript and run
inside a browser when it is deployed. You cannot run the code by using a
standard JVM and you cannot create a standalone Java application using this
API.
If you are indeed writing a web app, for testing, you can run it inside of
the GWT hosted mode browser by configuring a GWT module.

Re: How do I make a pretty, easy to use button without making custom images for each one?

Re: How do I make a pretty, easy to use button without making custom images for each one?
If you are able to use .pngs with a full alpha channel in your project (IE6 does not support them without a work-around - google 'ie6 png') you can have great success using images. If you only have a few different background colors on your site, than create a rounded corner - fill in the area that is the background with its appropriate color and leave the area that will form the face of the button transparent. Then, you can use those four rounded corners (in various colors) to round everything from buttons to containers. Simple set the background color of the button to be the color that you want it to be, and whala! Now you have buttons in any color :) To create the PrettyButton widget you can use a grid wrapped in a focus panel - just make sure to use setCellSpacing(0) and setCellPadding(0) on the grid. You can use the same method to create a PrettyCornersWidget that will take a widget as an argument, then wrap it in rounded corners.

Re: Panel not clearing?
You should use an Image widget instead of setText.
something like
*Image image = new Image();

*image.setUrl("'http://www.vella-gulf.navy.mil/Site%20Images/under_construction.jpg";);
*
*// Use image.addLoadListener(...) to manage loading errors

Re: how reset FileUpload?
it may depend of the way your form is built, but you can call reset() on the form object in javascript. This means that you need a JSNI call. A file input can be accessed in JS for security reason, but reseting the form will clear it. And all the inputs of the form... 2009/1/5 fother > > I need reset the FileUpload.. > In my form when I submit the form I need clear all fields.. > > it's possible? > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Can you be more specific what you want to know. I doubt that there are many people here who happily write your homework for you, so without a more specific description of where you are stucked with your understanding, examples, etc. there will most likely no answer to your mail.

Re: How do I make a pretty, easy to use button without making custom images for each one?
I've had great success using the 'sliding doors' technique for buttons. Just google for the phrase - here is a good example of the css needed - http://www.jorkas.com/lab/css/rounded_button/index.html I basically just created my own 'MyButton' class which extends InlineHTML and populates it with the html needed for the button, e.g.: "" + buttonLabelHtml + "" Then, I can instantiate with whatever label i want when I need a button, add clickListeners, etc. On Jan 2, 4:00 am, dduck wrote: > Hi, > > I would like to make abuttonthat looks like this: > > (|| text ||) > > ...where ( is a rounded left-end of thebutton, ) is a rounded right- > end of thebutton, || is a background and "text" can be specified e.g. > at creation.

Re: Properties file: how to use several maps with the same key and different values?
I hope you've worked through this by now, but the problem you're seeing is because each property key needs to be unique. You need to name your properties differently, such as: EVENTTYPE_1 = concert EVENTTYPE_2 = parade CATEGORY_1 = entertainment CATEGORY_2 = sports CATEGORY_3 = arts CATEGORY_4 = services EVENTTYPES=EVENTTYPE_1, EVENTTYPE_2 CATEGORIES=CATEGORY_1,CATEGORY_2,CATEGORY_3,CATEGORY_4 On Tue, Dec 23, 2008 at 7:09 AM, Fred Janon wrote: > I use several listboxes with a numeric key and a text as the value.

Re: IllegalStateException (onDetach) in Internet Explorer 6 and 7
We have found a fix to this problem.
We were doing an RPC call before building all the UI. And just moving
the RPC call to the end of the initialization routine has fixed the
problem.
Anyway, could there be a bug in the GWT code? I am asking because it
is not clear to me if calling a RPC method before constructing some
widgets should leave them in an illegal state.

Re: Waiting on multiple RPC calls
This is the first iv heard of this kinda thing. Im doing alot of
seperate rpc calls. could you give me an example of how to cache it
please.
currently im just doing:
/** An rpc call. */
private void getData() {
SignoffService.Server.getInstance().getData(new
AsyncCallback() {
public void onSuccess(User result) {
// success
}
public void onFailure(Throwable caught) {
// error
}
});
}
Thanks alot for your help,
Steve

Re: Approach for paging large dataset
I used continuous pagination inside a scrollTable loading 10 rows at a time. I used the client to keep a state of what rows it currently had and simply requested more using rpc when approaching the bottom. I ahd issues with getting the possition of the scrollbar as scrollPanel didnt have a scroll Listener at the time, i dont know if it still does. so i put the table in a scrollpanel and used the scroll listener of that. final product - very slick way to show 100's of rows of data. If you have more than that then i surgest incorporating a search feature or using standard pagination widgets from gwt-ext / ext-gwt On Jan 2, 8:43 pm, gregor wrote: > Check: > > http://code.google.com/p/google-web-toolkit-incubator/wiki/PagingScro... > > use JDBC (or ORM equivelents) to get pages over GWT RPC - don't clog > up HttpSession. > > regards > gregor > > On Jan 2, 7:14 pm, falcon_whiz wrote: > > > > > Hi all, > > I am creating an application where I need to send an array of objects > > from server to the client side using RPC. the problem is I want the > > dataset to be broken into pages so that the user isn't overwhelmed > > with data.

Re: Getting java.net.SocketTimeoutException: Read timed out
I had a similar problem and i eventually tracked it down to a looping rpc call. If you doing a very large request (or many in very quick succession) then you will have to read the apache docs and edit the settings in your web.xml (possibly "keep alive") although with the default settings of 1min before timeout this is unlikely. Hope this helps, Steve On Jan 4, 10:51 pm, rakesh wagh wrote: > Please provide more details on what you are doing. Are you getting > this error on client or server?
