Re: RequestBuilder with xml request and xml response

[Abdullah Shaikh]

RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, "url to the
servlet which response back with xml");
builder.setHeader("Content-type", "application/x-www-form-urlencoded");

builder.sendRequest(null, new RequestCallback() {

@Override
public void onResponseReceived(Request request, Response
response) {

String xmlData = response.getText();

//parse the xml data here
Document doc = XMLParser.parse(xmlData);
   }

@Override
public void onError(Request request, Throwable
exception) {
//handle error
}
} );

This should help.

Why History.newItem() always calls the onModuleLoad?

[compuroad]

I thought History.newItem() would only build the history stack.
However in my App it fires the EntryPoint onModuleLoad, restarting the
application.

What am I missing?

Re: Cross Domain Scripting

[Vishal]

Thank u for the corrections and your response.

To further clarify our problem domain.  We want a Microsoft .NET based
application to run our GWT app and and that server is on
xxx.somedomain.com.  To load up our GWT app , we wanted to source in
the cache.js and subsequent data transfers through RPC  from our java
based tomcat server , in the same domain but on a different host
yyy.somedomain.com. If I understood u correctly, the architecture that
will bypass SOP would be

* Create a Relay/Proxy on xxx.somedomain.com.. it is a IIS server and
no servlets on that host.
* The Relay as a relay should do , forwards the request ( any
request ) to yyy.somedomain.com.
* In the html src=http:// xxx.somedomain/g-control/gwtc/z/
z.nocache.js.
  This when loaded by the IIS server , actually relays the request to
yyy.somedomain.com.
* Any RPC executed on behalf of the downloaded js , will be to
xxx.somedomain relayed to yyy.somedomain.com

And thus we bypass SOP.

Have I understood this correctly.. ( even though it seems I have just
repeated your post ) and is it a well known practice top beat SOP ?

You can use a SimpleCheckBox instead of a CheckBox, to just have the

But you can also just tweak your CSS to target the input child of
the .gwt-CheckBox:

.gwt-CheckBox input {
   width: 1em;
   height: 1em;
   padding: 0;
   margin: 0;
}

A bit "low level" but quite "easy" nevertheless:

   myAnchor.getElement().cast().setRel("nofollow");

or if you don't like this cast() syntax:

   AnchorElement elt = myAnchor.getElement().cast();
   elt.setRel("nofollow");

A "reload" is an "unload" event, the very same that's also fired when
you navigate away or close the window/tab. In GWT, this is
WindowClosing and WindowClose.

Or are you experiencing another behavior in some browser?

Re: Saving form inputs for browser autocomplete

[Ben Harris]

There is a post on this somewhere, I just don't have the link.

1) Make a form with all the inputs and a submit button (In your HTML).
The action can be javascript:void(0). Give the form an id.
2) Do FormPanel.wrap(Document.get().getElementById(formID)) to get the
form.
3) You can add a handler to the FormPanel for input validation.
4) Add a JSNI native that creates a javascript function to call (like
this 
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html#calling).
The Java method it calls should grab the inputs you want. It will be
triggered by the submit button.
5) Call the above method
6) Change the FormPanel action to be javascript:[method name from step
4]

This doesn't work on Chrome though, because chrome needs a new page to
load so it knows the values were correct. Or something like that.

You can set the form to display:none, then add it as a widget to a
popup panel and remove the display:none. This way it will be hidden
till you need it.

Errors/Typos in GWT Docs

[Marty Hall]

I have been in Asia the last month doing training, so this is my first
look at the new (yay!) GWT 2.0 docs. GWT 2.0 looks great, but I did
notice a few small errors in the docs:

http://code.google.com/webtoolkit/gettingstarted.html
=

A) Under "Create your first Web application":
"create a new application called MyApplication" should be "create a
new application called MyWebApp". Also, I would suggest also saying
something like "if you use the Eclipse plugin described later in this
document, you can also do File > New > Web Application Project and
then interactively specify a package name".

B) Under "Run locally in development mode":
The sentence "Since this is your first time hitting the development
mode server..." is slightly inaccurate since the real issue is if it
is the first time PER BROWSER. I would suggest something like "The
first time you use a browser with the development mode server, it will
prompt..." Also, I again suggest that you list the Eclipse Plugin
command for running in development mode (R-click project, Debug As >
Web Application).

C) Under "Make a few changes":
In the first paragraph, "java files" should be "Java files". Also, the
last part of that same sentence ("in the case of this Quick Start...")
does not parse and needs to be reworded. Finally, in the last
sentence, change the colon after "Send" to a period.

D) Under "Setting up an IDE":
Since there is support only for Eclipse, I would change the title to
"Using the Eclipse Plugin" or "Eclipse Support" or some such. Also,
there should be a comma after "IDE" in the first sentence. Also, I'd
insert here a very short summary of what the Eclipse plugin does for
you. I would think the majority of users would use the plugin, but
this document somewhat implies that the command line is the normal
approach and the Eclipse plugin is an afterthought.

http://code.google.com/webtoolkit/doc/latest/ReleaseNotes.html
=

A) Under "Bug Fixes":
Issue 1574: #remoteCookie should be #removeCookie. Issue 3102:
#removeHandelr should be #removeHandler, and "has be" should be "has
been". Issue 3903: "pages no contain" should be something like "pages
no longer contain" or "pages do not contain".

B) Under "HtmlUnit and Test Cases":
In second bullet, change "continous" to "continuous".

C) Under "Problems?":
Add comma after "GWT Developer Forum".

http://code.google.com/eclipse/docs/using_sdks.html
=

A) I would be a bit more clear that you should select "Web Toolkit"
and point at the new GWT 2.0 installation. For those upgrading from
GWT 1.7, that is the part you have to change. The current screen shots
show only the App Engine part, which does not need to change.

http://code.google.com/webtoolkit/usingeclipse.html
=

A) For those upgrading from GWT 1.x, I would make it a bit more clear
that you have to download GWT 2.0 separately. Previously, downloading
the Eclipse plugin also gave you GWT, with no separate download
required.

B) Under "Create a Web Application", change "java package" to "Java
package".

C) Under "Run locally in Development Mode", this description of when
you will be prompted for the browser plugin is what I would like to
see under the same heading in 
http://code.google.com/webtoolkit/gettingstarted.html.

D) Under "Make a Few Changes", change "java files" to "Java files".

I am very pleased to see GWT 2.0 out. Keep up the great work!

Height Problem with FlexTable in GWT 2.0

[Shady]

After upgrading my GWT project from 1.7 to 2.0, I found out that the
cells in my flextable are NO LONGER taking into consideration the 100%
height that I am giving . In fact here is a simplified case that shows
the problem:

public void onModuleLoad() {
FlexTable f = new FlexTable();

Button b1 = new Button("Cell1");
b1.setWidth("100%");
b1.setHeight("100%");
f.setWidget(0, 0, b1);
f.getFlexCellFormatter().setRowSpan(0, 0, 2);

Button b2 = new Button("Cell2");
b2.setWidth("100%");
b2.setHeight("100%");
f.setWidget(0, 1, b2);

Button b3 = new Button("Cell3");
b3.setWidth("100%");
b3.setHeight("100%");
f.setWidget(1, 0, b3);

f.setWidth("200px");
f.setHeight("200px");
f.setBorderWidth(1);

RootPanel.get().add(f);
  }


Cells are actually expanding correctly in width (to 100%) but NOT in
height ! I tested it on 2 different browsers, tried changing the
RootPanel to the RootLayoutPanel, tried fixing column sizes but always
got the same problem.

Am I missing something or is it a regression in the new GWT 2.0 ? I
really need to have 100% height values in my FlexTable!!!

Thanks

Re: RequestBuilder call fails on FF

[Ihor Kaharlichenko]

You can try to install FireBug (see http://getfirebug.com/) and
monitor the request on the Net tab to see what happens with the
request. Both request and response bodies and headers can be seen
there. Give it a try and post the results here.

Re: How to implement a fancy zoom with GWT ?

[pohl]

Absolutely.   If another javascript manages to do something in a
browser, then you can do it in GWT.   A good starting place would be
to look at is the following class:

  com.google.gwt.animation.client.Animation

It's an abstract class that you extend.  There's a mechanism that
repeatedly calls this method that you implement:

onUpdate(double progress)

The "progress" argument will be between 0.0 and 1.0, which tells you
how far along you are in the animation step.   (Think of it as a
percentage.)  Using that number, you can decide, for example, exactly
how "zoomed", or "faded", or "moved" your widget or element is.  When
the animation starts, the value will be 0.0.  When it's done, it will
be 1.0.  In between, the Animation class provides a nice "easing
function" that gives something a bit more natural than straight linear
interpolation would.   The nice thing about it is that you don't have
to think about the easing function.  The abstract superclass will just
call onUpdate() and let you know how far along you are.

Re: Can java client use GWT RPC?

[Isaac Truett]

I'm sure with a little searching you can come up with information on
doing pure Java HTTP connections. There's probably something in the
Android API for that as well. But that's getting off topic for this
forum.

Re: GWT RPC error

[Sripathi Krishnan]

There are two separate google projects - GWT and Google App Engine (GAE).

If you use GAE, you *cannot* use Oracle database (or any other database for
that matter). You are tied to using GAE's data storage mechanism.

If you don't know or care about GAE, just disable it for your project (its
just a setting in your eclipse project). Once you disable it, you should be
able to access your Oracle database.

Re: GWT RPC error

[t.dave]

it looks like you're referencing code on the GWT client side that the
GWT compiler doesn't support.  this kind of problem can be tricky,
because it looks like it compiles ok in eclipse.  remember that your
GWT client packages will end up in the browser as javascript, and so
GWT only supports only a subset of the JRE in the com.x.client.*
packages.

i'd check for any references to Socket:

java.net.Socket is a restricted class


as well, check the JRE emulation reference for supported client-side
java packages.

Re: Javascript problem in cache.html

Sri,

Thanks, it worked! Once I set the style=DETAILED flag using the "GWT
Compile project" button in eclipse I soon discovered the problem. One
of my variables was null in some cases. Once I fixed this my
application works again.

Re: Problems reading the content of a text file.

[mdwarne]

Hi,
RequestBuilder sends a request to the server.  I've never used it (I
use GWT-RPC) .

But perhaps you need to put your server address into the request?

Or maybe  call the GWT.getModuleBaseUrl() or  GWT.getHostPageBaseUrl()
to get the Base URL you need, and concat the file name to the baseUrl?

Sorry if this is not helpful.
Thanks,
Mike.

Re: Saving form inputs for browser autocomplete

[skrat]

It's the very basic browser feature, without any extensions.  Just
click twice on input, or start typing in a field you have had already
submitted before, and previous values will be offered for you. This is
standard feature of FF, Chrome, and I guess some more browsers.

rel attribute on anchor tag

Getting User details in GWT RPC

[Pavi]

Hi,

I am trying to get user information in my GWT application while trying
to host it on the appspot. In my RPC service impl class I invoke the
following:

UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();

I plan to store the value of the user in the datastore, but the value
is always "null". Could someone please let me know if I am missing
something?

Thank you,
Pavi

Styling CheckBox

[Tim K]

I want to change the size of a com.google.gwt.user.client.ui.CheckBox
so that it grows/shrinks.  I am using a Chrome Browser. It zooms in
and out with Ctrl-Plus and Ctrl-Minus.

This entry in my css file had no effect.
.gwt-CheckBox {
  width: 1em;
  height: 1em;
  padding: 0;
  margin: 0;
}

Chrome's inspector displays this HTML.

Integration in external site

[shed]

Hi all,

I want to integrate my GWT project in an external Website. But I don't
want to use an IFrame. So I tried to load the compiled JS code in this
external site. But it doesn't work. I think that it has to do with the
"same origin policy" but I'm not really sure.

Hope someone can give me an example how I can integrate my GWT project
in an external site or can post some useful links.

Thank you very much!
Best Regards!

Debug Mode Tomcat

[Malli]

HI,

I'm using ANT for compiling  gwt  java class  into  corresponding js
and html files.After compiled successfully i copied all gwt html and
js files parallel to my  WEB-INF folder under my application name ,for
deploying war i'm using Tomcat .Now  i need to put the break point on
gwt java files which files comes under client directory  and debug
it .. can anybody help me out?.

For debugging the  normal java files like servlet or util files i'm
setting tomcat bat file as follows:

set JAVA_OPTS=-Xms256m -Xmx512m -XX:PermSize=128M -XX:MaxPermSize=256M
set JPDA_ADDRESS=1097

Re: Window formatting - Firefox vs. IE

[Jim Douglas]

David,

The selection of "quirks mode" versus "standards mode" is the biggest
factor I've noticed in the overall behaviour in IE8.  (I haven't
tested in IE6 or IE7.)

The quickest way to see if that's the issue is to hit F12 and try the
three different document modes.  If your stuff works in standards mode
and fails in quirks mode, change that to be the default version that
you serve up.

Jim.

Window formatting - Firefox vs. IE

[David C. Hicks]

I've got a couple of problems with some dialogs that are based on the
Window class.  I hope someone can point me to a quick solution.  It just
seems like I must be missing something.

My dialog based on the Window class has a number of panels in it.  Each
panel may have several widgets.  Those are all looking pretty good.  I
set the AutoHeight and AutoWidth properties for the Window to true.  Now
come the problems:

1) In Firefox, the dialogs look like they're almost perfect, except that
with text fields that are required, the little red icon on the right
makes the field larger than the dialog, resulting in a scroll bar being
placed below the widget/panel.  Is there a way to take that icon into
account so that the width works out correctly?

2) In IE, the dialogs end up taking the entire width of the browser, but
not the height (which appears to be correct).  How can I prevent this?

Thanks for any suggestions.
Dave

Jetty Classpath, Ant vs Eclipse

[Thad]

I'm using GWT 2.0.0 on Linux with JDK 1.6 targeting JDK 1.5.0 (for
compatibility reasons with older Macs).

When I launch DevMode via Eclipse, all runs fine.  It also runs fine
when deployed as a WAR file on Linux or on MacOS 10.5.  However if I
launch DevMode via ant from the command line, my application's
services Impl's seem to choose a different classpath.  Here's the code
snippet that throws an exception:

  // Parse the XML.
  InputSource source = new InputSource(bais);
  XPathFactory factory = XPathFactory.newInstance();
  XPath xpath = factory.newXPath();
  String expression = "//pa...@number='"+page+"']";
  result = (Node)xpath.evaluate(expression, source,
XPathConstants.NODE);

The classes are imported from the JDK's javax.xml.xpath package.
The exception trace points to the last line of the above snippet:

00:01:21.111 [WARN] Error for /webclient/getImageServlet
java.lang.NoSuchMethodError: org.apache.xpath.XPathContext.(Z)V
at org.apache.xpath.jaxp.XPathImpl.eval(XPathImpl.java:207)
at org.apache.xpath.jaxp.XPathImpl.evaluate(XPathImpl.java:476)
at com...getLayerPage(GetImageServlet.java:647)

This seems to indicate that when run from the command line the XPath
is being derived from Xalan, which does not have the particular
evaluate() method I'm using.

My ant project class path is

  



...

  

  

${third.party.libs} includes Xalan, JDOM, JAI, and other jars.  Both
gwt-user.jar and gwt-dev.jar are in war/WEB-INF/lib.  My devmode
target looks like the ones in the 2.0.0 samples.

Any ideas?

flextable column widths and onLoad...

[golfdude]

I have a table widget ( derives from flextable ) in which I set the
columns widths based on a percentage of offsetWidth. In one table, I
load the contents of this table in a widget constructor ( which
creates the table ). At that time, the columns are not rendered
correctly. After the page is loaded, if I refresh or sort, then the
column sizes are set correctly ( since the resize is called ). I have
overloaded onLoad method in my table widget which calls resize. I also
call resize when the data is loaded. But the initial loaded table have
wrong sizes. Any ideas why this could be happenning ?

Thanks

Re: Saving form inputs for browser autocomplete

[Michael W]

Skrat,

Are you talking about the Google Autofill, Roboform Autofill feature?
Which means browser remembers your form entry and next time once you
click Autofill from browser, the form is refilled.

Or just want to prepopulate your form processed by your program.

Re: GWT 2.0 Panels

[Ian Bambury]

You can't use CSS file syntax you have to use DOM style (i.e. 'cssFloat' not
'float').

Try something like:


FlowPanel searchPanel = new FlowPanel();
Label leftPanel = new Label("Left"); // Or whatever
Label rightPanel = new Label("Right");

RootPanel.get().add(searchPanel);
searchPanel.add(leftPanel);
searchPanel.add(rightPanel);

searchPanel.setWidth("100%");
searchPanel.getElement().getStyle().setProperty("border", "1px solid
black");

leftPanel.getElement().getStyle().setProperty("cssFloat", "left");

rightPanel.getElement().getStyle().setProperty("cssFloat", "right");

Ezra your post got me thinking about the browser settings.  And what I
discovered was that if the setting "Work Offline" in the File menu is
checked, or selected,
then the stack is generated.  But simply by unchecking this setting, I
can resolve the error and connect to the server.  Of course this makes
sense, I just hadn't
thought of it because often enough Firefox will simply prevent the
entire page from loading and give me the warning message in the
browser window.  But sometimes Firefox will go ahead
and load the page and if it does and if it's configured to work
"offline" then of course there will be a problem connecting to the
server.

So I think I've resolved this problem for now.  Thanks to you both.

Re: Using Constants server-side?

[El Mentecato Mayor]

Search this list for a couple of solutions that allow you to reuse the
client-side interfaces.  You will need to make sure that both the
properties files and the interfaces exist on both the client and
server sides.

I opted to simply use ResourceBundle and make my properties files
available on the server-side.  The only other thing you need to take
care of (in both scenarios) is knowing what Locale to use.  You
usually want to set it according to the locale that the client is
using, which doesn't necessarily correspond to the same locale that
the server-side JVM is running as.

Like I mentioned in the original post:

The sample code on that page has been very confusing to me, method
names aren't even consistent across the examples.

GWT 2.0 Panels

[mwaschkowski]

Hi,

I've been having great difficulty with 2.0 panels. I've read over the
docs at:

  http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html

and moved over to standards mode. I've found that a lot of widget that
used to display scrollbars just don't anymore. I've tried using the
new layoutpanels, but getting hung up now because of sizing issues - I
now have to declare the sizes explicitly, and now there are layout
issues (some of the page not being displayed depending on the
browser).

Well, first off, I decided to do something simple like replace my
horizontal panel with a flow panel. This horizontal panel (hp) was
100% width, had a widget on the left and a widget on the right.
Because the docs cautioned that HorizontalPanels might not work with
standards mode, I did the following (using the float suggestion in the
docs):

FlowPanel searchPanel = new FlowPanel();
DOM.setElementProperty(searchPanel.getElement(), "border", "1px
solid black");
searchPanel.setWidth("100%");
searchPanel.add(leftPanel);
DOM.setElementProperty(leftPanel.getElement(), "float", "left");
searchPanel.add(rightPanel);
DOM.setElementProperty(rightPanel.getElement(), "float", 
"right");

As well, I tried to add a border so I could better see the layout.
Neither the border is working, nor the floating of the widgets, help!

Thanks,

Mark

NumberFormat.getCurrencyFormat

[Peter Ondruska]

I have default locale set to "en" and would like to format currencies,
e.g. NumberFormat.getCurrencyFormat("CZK").format(c) but it fails as
CZK (Czech Crown) is not available in "en". How would I do that
without switching to "cs" locale?

JClassType implements HasAnnotation, so you just have to replace your
call to getMetaData to a call to getAnnotation, replacing the name of
your annotation with its actual class, e.g.

   public @interface Table {
 String[] value();
   }

   @Table({ "foo", "bar", "baz" })
   public class MyTable { }

   JClassType sourceType = ...;
   Table tableAnnotation = sourceType.getAnnotation(Table.class);
   for (String v : tableAnnotation.value()) {
  // will loop over "foo", "bar" and "baz"
   }

Re: JAXB in model classes also used by GWT RPC

[Mike Bedard]

I was alwayas under the impression that third party jars could not be included 
in the client side code because ultimatley this code is complied to 
javascript.  GWT complier only handles a subset of the Java API that's where 
the javax package is...
 
To get RPC to work you need to make changes in the client and server.  
 
If I'm off track and you

Thanks for the suggestion.

Ugh.  That feels pretty hacky, but may just be the best option.

Re: StatusCodeException

[Ezra]

Hi Leslie,

I had a similar issue which was caused by having my ports not match up
correctly. If you take a look at the mozilla developer page ,
https://developer.mozilla.org/en/Same_origin_policy_for_JavaScript, it
explains the browsers same origin policy. For example, localhost:1234
cant get javascript files from localhost:8080 in Firefox.

Its possible this has nothing to do with your problem but I was also
getting a status code of 0. If the server wasnt working properly I
think you would get a 404 error.

Let me know if this helps,
Ezra

Hyperlink ClickHandler help

[Peter Ondruska]

Dear all,

In GWT 2.0 Hyperlink.addClickHandler is deprecated and I should use
FocusWidget.addClickHandler. However no matter how hard I try I cannot
get this working. Would you help me please with an example of how to
add ClickHander to Hyperlink in GWT 2.0.

Thank you,

Peter

You can only use widgets () as direct children of other
widgets, or descendants of  widgets.

Where the hell have all of you been seeing this code to add widgets to
the page? Widgets should be children of other widgets, except for two
cases: RootPanel/RootLayoutPanel, and those widgets created by their
wrap() static method.
In your case:

   RootPanel.get().add(test);

If you want to have an Image widget as a component of your
BinderUiTest object, you have to turn it into a Composite (probably
using an HTMLPanel widget as the root object).

Re: GWT Developer Plugin not working IE8

[googelybear]

It seems that when I select "Run as > Administrator" the plugin gets
installed into the administrator's app data directory. when I manually
copy the oophm.dll file to my home directory and issue the suggested
command (regsrv32.exe ) I got it running. It this a bug
or a feature? Is there a proper solution for this?

thanks!

Re: Can java client use GWT RPC?

[ailinykh]

Thank you!
This is what I'm going to do. But I see one problem here. I'd like to
use Google's authentication.
As far as I understand it is HTTP based. I don't see any way how to
use it outside browser.
Any ideas?

Thank you,

This is planned, but not yet available (there's a TODO in the code),
unless of course you patch GWT.

Re: GWT 2.0 serialization policy file

[Rodrigue Lagoue]

It's really frustrating. since the error tells: "Type '*java.lang.Boolean*'
was not included in the set of types which can be serialized by this
SerializationPolicy or its Class object could not be loaded. For security
purposes, this type will not be serialized.: instance = true"

When i try to make the following generic rpc call

@RemoteServiceRelativePath("testService")
public interface TestService extends RemoteService {

public , V extends Serializable, D extends
Serializable> T execute(
Action action);
}

here is the implementation:

@SuppressWarnings("serial")
public class TestServiceImpl extends RemoteServiceServlet implements
TestService {

@SuppressWarnings("unchecked")
@Override
public , V extends Serializable, D extends
Serializable> T execute(
Action action) {
System.out.println("action.data: " + action.toString());
DefaultResponse result = new DefaultResponse();
result.value = Boolean.TRUE;
return (T) result;
}

}

Thanks

hi!

No my classes have a no arguments constructors. There are just defined in
another project. The GWT project uses it from a jar file.

JFTR: Just checking the content-length doesn't work in all cases.
If the client decides to send the request with chunked encoding
you don't have that information at that point of time. In that
case you have to read in the data and close the moment the limit
has been reached.

Hi Isaac,

Looks like you read my mind because this exactly what I've started
experimenting with.

My code now looks like this:

public class JSNIJs {

public @interface JsResource {
String[] resources();
}
}

public class AWrapper {
@JsResource(resources = { "b.js", "a.js" })
private class Js extends JSNIJs {

}

public AWrapper() {
GWT.create(Js.class);
}
}

public class JSNIGenerator extends Generator {

@Override
public String generate(TreeLogger logger, GeneratorContext context,
String typeName) throws UnableToCompleteException {
TypeOracle typeOracle = context.getTypeOracle();
try {
JClassType userType = typeOracle.getType(typeName);
JSNIJs.JsResource resource = 
userType.getAnnotation(JSNIJs.JsResource.class);
if( resource == null ) {
logger.log(Type.ERROR, "JSNIJs needs to be 
annotated with @JsResource");
throw new UnableToCompleteException();
}

String[] resources = resource.resources();
if( resources.length == 0 ) {
logger.log(Type.ERROR, "@JsResource needs to 
hold at least one value");
}

for( String r : resources ) {
OutputStream outStream = 
context.tryCreateResource(logger, "test/js/" + r);
if( outStream != null ) {
outStream.write("--- Used 
---".getBytes());
context.commitResource(logger, 
outStream);  
}
}
} catch (NotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return "testgen.client.JSNIJs";

}

This now writes an JS-Entry for every JS-File found. Ideally I could
write everything to one big fat-File but I couldn't find a way to
append something to a file until now in the generator API.

Thanks for your help.

Creating child node with child nodes

[Komal]

Hi,

I am trying to insert new child nodes
which contain n no of child nodes in them
eg:


   
   This is the code 
   



adding new child node would be like this
eg:

   
   This is the code 
   

   This is the code for line 2
   This is the new code for line 2
   This is another code for line 2



but when I try to create a new line node
it is getting created as

hence the children  tags are not getting appended

heres the code:

for (int i = 0; i < files.getLength(); i++) {
Element file = (Element) files.item(i);
if (file.getAttribute("name").equals("newfile")) {
Element linenode = customerDom.createElement("line");
linenode.setAttribute("no", "600");
Element codenode = customerDom.createElement("code");
codenode.setAttribute("user", "a");
codenode.setNodeValue("This is the code for line 2");
linenode.appendChild(codenode);
Element codenode2 = customerDom.createElement
("code");
codenode2.setAttribute("user", "b");
codenode2.setNodeValue("This is the new code for line 
2");
linenode.appendChild(codenode2);
file.appendChild(linenode);
}
}

Please let me know where I am wrong

Thanks,
Komal

Re: Getting file size in client side

[Manuel Carrasco Moñino]

NO, you have to send it to the server where you can read the
content-length in server side an close the connection early.
Neither you can cancel the upload process once the form has been
submitted, only the server can do.
You can take a look to the gwtupload library which does it.

Is this the problem with the classes you want to serialize not having

Re: GWT Developer Plugin not working IE8

[googelybear]

works for me in 64bit win 2003 server with 32bit IE8. But only when
