Re: Navigate to new page
Another way!!! You can have this loginpanel in an absolute panel which is present in the root panel. When u are navigating to the next page, just remove this absolute panel from the root panel and call the next entry point. U can follow the same process for navigating to all the pages that would come up. regards, abhiram On Wed, Jun 3, 2009 at 2:50 PM, ashik wrote: > > Hi I am using GWT in my application.

Doubleclick event handling
Could I please get some clarification on how to use the double click
event handling? The classes are there (e.g.
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/event/dom/client/HasDoubleClickHandlers.html)
but don't seem to be implemented anywhere.
I would like to add double click handling to an Image, could someone
please give me some example snippet of code on how to do this? I've
tried simple things like extending Image and implementing
HasDoubleClickHandlers, e.g.
private class CommandButton extends Image implements
DoubleClickHandler, HasDoubleClickHandlers {
private HandlerManager clickHandlers = new HandlerManager(this);
public CommandButton(){
super("images/favicon-2.png");
addDoubleClickHandler(this);
}
@Override
public void onDoubleClick(DoubleClickEvent event) {
Log.debug("doubleclicked command button");
}
@Override
public HandlerRegistration
addDoubleClickHandler(DoubleClickHandler
handler) {
return
clickHandlers.addHandler(DoubleClickEvent.getType(),
handler);
}
@Override
public void fireEvent(GwtEvent event){
handlers.fireEvent(event);
}
}
but of course this doesn't handle double click events.
Thanks!

Cross domain issue - not w/ RPC... Please help
What I am trying to do seems trivial but I must be missing something... I want to host the GWT application (CSS, JavaScript) on one domain: http://www.server-a.com/gwtApp/ and then have the html that hosts the application live on various other domains (sort like what adWords does): http://www.server-b.com/hostpage.html I haven't gotten to the point where I'm doing RPC (I plan to use JSONP). The issue seems to be in the sniffer code for deferred binding -- like it's having trouble loading the right cache.js file. When I compile w/ PRETTY and look at the errors in Firebug i see the following... Permission denied to get property Window.prototypea [Break on this error] if ($wnd.prototypea) $wnd.prototypea.onScriptLoad (); I have seen references to a "mashup mode" in the forums but i have a feeling that's not around anymore.

Re: Calling java scrip function
Hi,
You can use a native method call to execute a javascript function.
public native void callFunction() /*-{
if (typeof myFunction== 'function') {
myFunction();
}
}-*/;
Now inside your onClick() method call this method.
public void onClick(Widget sender) {
callFunction();
}
Cheers,
Kamal

Multiple modules but deploy common code to common place
I have a very large application that I need to deploy with multiple module. Our application is made of with smartgwt as well. When we compile there seems to be a lot of duplicate "common" code. Each module has the same css and theme information. So after compiliation I end up with ... Module A - it's specific files - it's common stuff that it could share with other modules like it's images. Module B - it's specific files - it's common stuff that it could share with other modules like it's images. Module C - it's specific files - it's common stuff that it could share with other modules like it's images. Is there a way to direct all that common stuff to a common stuff particularly the images and theme stuff since that takes up the bulk of the app size. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

delayTestFinish is not delaying the test
I'm using the GWT Eclipse plugin with the latest GWT 1.6. My test
looks like this:
public class MyTests extends GWTTestCase {
public String getModuleName() { ... }
public void testAddAction()
{
MyServiceProxy proxy = new MyServiceProxy(
new MyServiceCallback()
{
public void OnData(Data data)
{
finishTest();
}
});
proxy.GetData(); // Execute Web Service (REST) call
delayTestFinish(6000); // Delay for 1 minute
}
}
I'm running this test with "Rght-Click/Run As/GWT Junit test" on the
function. The test running successfully, and the call to the remote
service is executed, but there is not enough time to get the callback
since the delayTestFinish is not waiting for the specified delay. In
fact it's not waiting at all - it just jumps through.
When I check the source code for the delayTestFinish function I see
something like this:
public abstract class GWTTestCase extends TestCase { ...
protected final void delayTestFinish(int timeoutMillis) {
// implemented in the translatable version of this class
}
...
}
What is the translatable version of the class. How can I see what is
the generated result? What am I doing wrong?

Re: GWT Dynamic Menu from XML File. How to Reflect Class of the Composite?
Hello Todd, Thanks for your quick answer.
Yes I know I can do that, but that way, everytime that I want to
change the menu, I have to change the code, and thats what I want to
avoid.
I really want to do that because I'm starting a project, and I know
(by experience) that the menu will have a lot of changes.
But do you think that I souldn't use the client side solutions? Like
the "gwt-ent" and "gwt reflection" libraries? What is the problem with
them?
My last solution is to generate all the menu from the XML, and
interpret the actions with a client side function. Example, every
action like doAction("Home"). This solution is very likely yours, and
I get a semi-dynamic Menu.
Regards.

Re: How does a user change the default css theme?
The xml file for your module (Module.gwt.xml) is used to compile your application and is not used at runtime. By including the in your module you are telling the compiler that it needs to inject the standard.css file into your application. If you want to change styles you will have to use something like JSP or PHP to add a tag in the header like .

Multimodule GWT with App Engine
After attending Google I/O this year and seeing the magic of GWT, I've recently switched my developer tools to include Java and GWT. Please excuse my questions if they have obvious answers, I'm only just beginning in both of these areas. I'm building an application hosted on App Engine with GWT for client presentation and logic. I'm using Eclipse and the Google plugin. I have everything working smoothly and am very impressed with the Google team's thinking and organization. I understand clearly how to setup an Eclipse project for GAE and a single GWT Client App, but in my particular case, I need to build multiple GWT clients that all access one GAE app. The GWT clients aren't related except that they access the same models/data/services in my GAE app. For example, I may have a GWT front end for the general public, a separate GWT application for administration, and several 'widget' applications for the public to embed in their own web pages. In this scenario, I need to setup at least 3 completely independent GWT modules in Eclipse in the same project. My GAE servlet/RPC code is also in this project. Can anyone suggest how I might accomplish this? Even if I do get it setup, I'm wondering about these potential issues: 1. How do I make sure that each GWT client gets compiled when I do a 'run..' in Eclipse? 2. How do I specify which client runs when testing? I'm assuming a suggestion might be to build independent Eclipse projects, BUT I really want to keep the whole thing together and post the entire project to GAE at once...

Here is what I got out of the talks: - Code Splitting: GWT.runAsync(): allows the developer insert sections of code to split. You initial code might be maybe 1MB of script but code splitting can get it down to a couple hundred kb to load faster. Code will be loaded asynchronously as needed. - OOPHM (Out of Process Hosted Mode): will be available in GWT 2.0. Search for OOPHM for details. I am currently using it with trunk and love it. :) - SOYC (Story of Your Compile): This is a new tool that will help developers see the impact of code splitting. - improved layout for several Widget (ex: DockPanel) - Javascript compiler optimizations.

Re: GWT Dynamic Menu from XML File. How to Reflect Class of the Composite?
You might want to avoid anything to do with reflection altogether. If
you xml is something like this:
Button1
Widget1
Button2
Widget2
Try something like
if ("Widget1".equals(menuItem.getName())) {
horizontalPanel.add(new Widget1());
} else if ("Widget1".equals(menuItem.getName())) {
horizontalPanel.add(new Widget2());
}
Unless you have tons of Widgets this will be manageable. I believe
this method may also help avoid issues with the -XdisableClassMetadata
flag in the upcoming GWT 2.0.

Debug not working with 1.6 in eclipse ganymede (3.4) on Ubuntu Jaunty (9.04)
Eclipse seems to function just fine, and I am able to debug regular java applications, but when I run a GWT app in hosted mode it ignores my break points. I know that it is executing the code. but it does not matter where the breakpoint is it does not stop.

Deploying GWT 1.6.4 RPC Web App to Knopflerfish OSGi Framework
Hi everyone! I'm trying to get the simple Web application in GWT 1.6.4 featuring GWT RPC to work in Knopflerfish OSGi framework 2.3.1 (an implementation of the OSGi framework like Equinox). For that matter I created an OSGi bundle from the GWT project and added an implementation of BundleActivator in which I register the client-side Web page and the server-side GWT RemoteServiceServlet with the OSGi-defined HTTP Service. Separately, I created an OSGi bundle from gwt-user.jar and exported the required packages for RPC but not javax.servlet as this is already exported by the JSDK in Knopflerfish. When I start the bundle created from the GWT project, the BundleActivator.start() method is executed and the client-side Web page is successfully registered in the HTTP Service. When I open my Web browser (Mozilla Firefox) and point it to the given address, I can view the Web page. Unfortunately, I get a java.lang.IncompatibleClassChangeError during execution of the start method from within the Knopflerfish OSGi framework apparently due to javax.servlet.Servlet. If I try to define a traditional Servlet in the same project and register it from the BundleActivator, everything works fine. Thus, my conclusion is that the problem is related to RemoteServiceServlet inheritance of javax.servlet.Servlet which doesn't comply with Knopflerfish OSGi framework definition of javax.servlet.Servlet. It looks like as if a definition of Servlet is used when I compile the GWT project with GWT-generated Ant file and another one is made available by the Knopflerfish OSGi framework, if I'm not mistaken about the meaning of java.lang.IncompatibleClassChangeError. I tried both to export and not to export javax.servlet from the OSGi bundle encapsulating gwt-user.jar but this didn't change anything. Some related info. I read the post by Ian Bull on his blog at http://blog.ianbull.com/2008/09/gwt-and-osgi.html but that refers to a previous version of GWT and uses Eclipse Equinox, not Knopflerfish. Thus, I couldn't figure it out from there. Thanks in advance, Gia --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

dictionary or overlay type?
I've been using dictionaries for a while and they've worked well but I needed something a bit more expressive so I turned to overlay types. (side note: docs seem to claim this is a new feature to 1.6 but what makes it a 1.6 feature?) The overlay types are great because I can use them directly or if I need a bit more control I can wrap them around JSON types. But my question is ... why would anyone ever use dictionaries? Aren't overlay types much more powerful? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT Dynamic Menu from XML File. How to Reflect Class of the Composite?
Hello Everyone, I'm trying to make an Dynamic Menu in GWT, reading it from an XML file. The XML file must have the button name and the action (the composite associated that will be added to an Horizontal Panel). To make the action, a need to do Reflection of the Class, wish is given me a lot of problems. I've tried 2 different solution, Client Side and Server Side. On Client Side I've tried "gwt-ent" and "gwt reflection" libraries, but I've got a lot of errors and its necessary to set what Classes will be reflected (which I don't want because I want a completely dynamic Menu, and not semi-dynamic). On Server Side, I've tried to return the menu but its not possible to deal with client side widgets on server side. So I tried to make the reflection and return the instance to the client, but on server side its no possible to get an client side Class. Anyone knows other solution? I'm doing something wrong? How can I reflect the class to put the Composite on the Horizontal Panel? Thansk for your help.

Re: IE: history token lost on http --> https redirect
I has some issues like this also, what i did was update my site to
always use fully qualified names. How I did this for GWT, i created a
RPC call back to the server to get the web server name and then always
added this to my pages.
Below is the code on the server side.
package com.cindiescreations.CindiesCreations.server;
import javax.servlet.http.HttpServletRequest;
import com.cindiescreations.CindiesCreations.client.RootURL;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class RootURLImpl extends RemoteServiceServlet implements
RootURL {
private static final long serialVersionUID = 1L;
@Override
public String getRootURL(String nop) {
HttpServletRequest req = getThreadLocalRequest();
String reqUrl = req.getRequestURL().toString();
reqUrl = reqUrl.substring(0, reqUrl.length()-25);
return reqUrl;
}

Re: PushButton w/ image: How to avoid grey background
Anders,
I do this in my app. I call it an InvisibleButton. All you need to do
is alter the CSS. I copied the CSS from GWT's PushButton and renamed
the gwt-PushButton part to mm-InvisibleButton. You don't even need to
do that if you want that behavior for all of your push buttons. Simply
alter the gwt-PushButton CSS. Here's the CSS I use for my
InvisibleButton:
.mm-InvisibleButton-up,
.mm-InvisibleButton-up-hovering,
.mm-InvisibleButton-up-disabled,
.mm-InvisibleButton-down,
.mm-InvisibleButton-down-hovering,
.mm-InvisibleButton-down-disabled {
margin: 0;
text-decoration: none;
}
.mm-InvisibleButton-up,
.mm-InvisibleButton-up-hovering,
.mm-InvisibleButton-up-disabled {
padding: 3px 5px 3px 5px;
}
.mm-InvisibleButton-up {
cursor: pointer;
cursor: hand;
}
.mm-InvisibleButton-up-hovering {
cursor: pointer;
cursor: hand;
}
.mm-InvisibleButton-up-disabled {
cursor: default;
opacity: .5;
filter: alpha(opacity=40);
zoom: 1;
}
.mm-InvisibleButton-down,
.mm-InvisibleButton-down-hovering,
.mm-InvisibleButton-down-disabled {
padding: 4px 4px 2px 6px;

Re: Referencing other projects
1. StartMenu needs to be part of a GWT module.
2. You need to inherit that module.
3. It won't work anyway, since you can't use JFrames in a GWT client.
Reference:
http://code.google.com/webtoolkit/doc/1.6/RefJreEmulation.html
There used to be a page on modules, too, but I can't find it in the
1.6 docs. Anyone know what happened to it?

Referencing other projects
Good day all. I'm having a slight issue with what was(hopefully) to be
a simple application using GTW.
All I am doing is creating a button which, when clicked, refences
another project I have created, to play a pacman game. Here is the
click handler for the button.
public void onClick(ClickEvent event) {
new StartMenu();
}
StartMenu is the opening class, which creates a new JFrame, and begins
the game. I have imported the project already, however, I have
recieved the following error-
No source code is available for type Gui.StartMenu; did you forget to
inherit a required module?
Note- Gui is the package
The source code is there, as I can look at it. Any thoughts?
Oh, I also use eclipse, so if that makes a difference.

RPC/Serialization problem with StockWatcher tutorial
I'm going through the StockWatcher tutorial and I get to the RPC part
(http://code.google.com/webtoolkit/tutorials/1.6/RPC.html).
At the first test point I get this error message as expected ...
[ERROR] Type 'com.google.gwt.sample.stockwatcher.client.StockPrice'
was not serializable
and has no concrete serializable subtypes
However, after putting in the code to "fix" it ... I still get the
same error. What am I missing?
Here is my StockPrice class ...
package com.google.gwt.sample.stockwatcher.client;
import java.io.Serializable;
public class StockPrice implements Serializable {
private String symbol;
private double price;
private double change;
public StockPrice(String symbol, double price, double change) {
this.symbol = symbol;
this.price = price;
this.change = change;
}
public String getSymbol() { return this.symbol; }
public double getPrice() { return this.price; }
public double getChange() { return this.change; }
public double getChangePercent() {
return 100.0 * this.change / this.price;
}
public void setSymbol(String symbol) { this.symbol = symbol; }
public void setPrice(double price) { this.price = price; }
public void setChange(double change) { this.change = change; }
}

DockLayoutPanel from Google I/O
Hi all, At the GWT sessions at Google I/O last week, we saw a demo of the new DockLayoutPanel with horizontal and vertical splitters. I think the speakers mentioned that this panel would be available in the trunk, but we checked out the code and can't find this widget anywhere. I was wondering if this panel even is in the trunk, and, if not, if it will be made available to us any time soon. It does exactly what we are striving to do with our layout and would be perfect for our application. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Referencing Shared Library
I have code a set of Java POJOs within my project that are used to transfer information around the application. I'd like to move them into a simple Eclipse project so that they may be used by other components. When I create a new Java project and move the POJOs to this project, I add the new project to the existing Project's build path. This resolves all classpath issues within Eclipse, but at runtime the GWT application fails with messages such as: "No source code is available for type foo; did you forget to inherit a required module?" How can I setup a relationship in GWT to access the shared library? Does the shared library need to be a GWT module? Ideally, I'd like to keep it as a simple, non-GWT Java library with no dependencies. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hyperlink changing style
I was trying to change style on hyperlink when clicked, but no change

Here's the code to change Hyperlink default:
.gwt-Hyperlink a:link {

.gwt-Hyperlink a:visited {
}
.gwt-Hyperlink a:active {

Re: Expire an idle session
I can remember that I used this method for setting the time out through the
code; however not quite sure why that method is not working for you.

Hi Hez,
As Tony said, setting the session time out in the server would be the
better way.
I guess that you are trying to set this timeout in client side because
you let individual users configure their session time out period. If that
is
the case, then you will have to follow the way that have mentioned.
HTH,
Kamal

Re: Expire an idle session
Hi Kamal
I removed the cookies too.
BTW, I saw some example that set the timeout like the following:
HttpSession session = getThreadLocalRequest().getSession();
session.setMaxInactiveInterval(1000 * 60);
I tried the above code before adding session-timeout in web.xml.
That doesn't work in my case, do you have any idea when to
use HttpSession.setMaxInactiveInterval()?

What about timing out the session on the server?
Assuming that you're using a Java application container on the server,
you can add the following to web.xml:
5
This will cause the server to time out connections after five minutes
of inactivity. With this technique, it's actually possible to
intercept requests made after a time out in the onFailure() handler
and to take some kind of action (i.e., redirect to a login screen).

Re: Don't obfuscate Java methods when passing instance to JavaScript
Of course this also means that an instance created in JavaScript and
passed into Java is not an instance of com.mypackage.Foo... it's a
JavaScriptObject.
Good points, though.

Re: Don't obfuscate Java methods when passing instance to JavaScript
I think I can see what you're saying... But what about objects that
are not created in JavaScript? Suppose the object/class in question is
instantiated in the Java world and passed over to JSNI?

Re: Work around for Element.setAttribute("style", "value") in IE ?
I was under the assumption that any of the static DOM methods should
be eschewed in favor of the methods in the Element overlay types
(where they exist).
so Element.getStyle().setProperty() vs. DOM.setStyleAttribute()
Though both should currently work

Try
DOM.setStyleAttribute(Element, "backgroundColor", "#ff")
(you also need to use camelCase for the style you are changing).

Re: Expire an idle session
Hi
Yes, it is working by setting the timeout in the server.
To summarize, the following are what I did:
1) Configured the session timeout in web.xml (say for 1 minute):
1
2) Then create a session in the login RemoteServiceServlet:
/* user is authenticated */
HttpSession session = getThreadLocalRequest().getSession();
3) And check if a session has expired at the beginning of every RPC method:
HttpSession session = getThreadLocalRequest().getSession(false);
if (session == null) {
/* means the session has expired */
}

Work around for Element.setAttribute("style", "value") in IE ?
Hi,
Doing a Element.setAttribute("style", "background-color: #ff")
works fine in Firefox but has no effect in IE.
Is there any work around for changing dynamically a style in IE ?
The post:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/4f99ff04a1bffe46/46f574d1e73dce9d?lnk=gst&q=setAttribute+style+ie#46f574d1e73dce9d
provides a way to load a css file dynamically for IE, but how to
change just an attribute ?
Thanks !

Re: PagingScrollTable not removing row
Hi
as far as I can see the error is here:
for(int i = 0; i < leftRowIds.length; i++) {
leftDataTable.removeRow(leftRowIds[i]);
}
turn it around:
for(int i = leftRowIds.length; i >= 0; i--) {
leftDataTable.removeRow(leftRowIds[i]);
}
otherwise while deleting the rows you change there index and get
unpredictable results!

GWT application switching between http and https
I am very new to using GWT and following tutorials and seeing what I can do with the toolkit. I was wondering if GWT can being used in the following situation? An example application could have an open area that allows users to browse and select data/products they want within an unsecured area of the web application. Part way through the user needs to login or provide data that needs to be communicated back to the host in a secured fashion. After this the application might then allow the user to work again with unsecured data. This is quiet general but what I am interested in is the movement of unsecured GWT pages to secured GWT pages. The user could work through the following flow. browse products, (unsecured) --> review basket of selected products, (unsecured) --> login to account, (secured) --> provide payment details, (secured) --> review confirmation screen, (unsecured) So when I am looking though the GWT widgets I am not sure how I make my application jump between secured and unsecured pages. Can I instruct hyperlink widgets to communicate back to the same server but over https? The example above is for a simple shop and I can understand how to do this in other frameworks so thought it best to be used in an example. How does the community get round this problem and are there any examples I can read to get a better idea? Any thoughts on where to look would be a great help.

Re: SliderBar (GWT incubator)
Hi,
you need to implement SliderBar.LabelFormatter to configure how the
labels are displayed.
It has one method to do that:
public String formatLabel(SliderBar slider, double value)
To make the slider-bar itself visible use the CSS rules defined in the
docs:
* .gwt-SliderBar-shell { primary style }
* .gwt-SliderBar-shell-focused { primary style when focused }
* .gwt-SliderBar-shell gwt-SliderBar-line { the line that the knob
moves along }
* .gwt-SliderBar-shell gwt-SliderBar-line-sliding { the line that
the knob moves along when sliding }
* .gwt-SliderBar-shell .gwt-SliderBar-knob { the sliding knob }
* .gwt-SliderBar-shell .gwt-SliderBar-knob-sliding { the sliding
knob when sliding }
* .gwt-SliderBar-shell .gwt-SliderBar-tick { the ticks along the
line }
* .gwt-SliderBar-shell .gwt-SliderBar-label { the text labels
along the line }
Hope that helps!

UnsatisfiedLinkError when trying to use JSNI
Hi all, I'm using GWT 1.6.4 on Windows through Eclipse plugin. The JRE I'm using is the 1.6.0_13. I'm trying to use JSNI in my GWT app but I have troubles. As far as I've understood, to use JSNI I have to "simply" create a native method in my class and call it from a regular Java method. But during the execution (in hosted mode), I've an UnsatisfiedLinkError when trying to call my method. Actually, I've the same error when I first tried to use the URL.encode () method (the module does inherits com.google.gwt.http.HTTP). I guess I've missed something because I'm new to GWT. Any ideas?

How does a user change the default css theme?
GWT 1.6 has three css themes, standard, chrome, and dark. As time passes I expect there will be more. With that in mind I want to use those themes, and let each user choose his/her own theme for the application. My intention is to have a listbox with the available themes, thus allowing the user to choose a theme and have that theme saved from session to session, probably with a cookie. I am having a couple of problems. 1) I have no idea how to fill the listbox, other than by hardcoding the theme names. 2) I have no idea how to tell the xml that we are changing themes. (I am not even sure that the xml is where the change needs to happen.) I have looked and so far haven't found a tutorial or example that deals with this issue.

Issue with compiling GWT with many libaries
Hello all, I am trying to run an ant build script that compiles GWT. This script includes a large number of libraries, each with a relatively long path. My GWT code only touches some of these libraries; however, it is convenient to include all of the libaries from the directory containing all libraries that I use for this and all of the other applications I am developing. Here is the relevant portion of my build script: When I try to run this, I get the following error: java.io.IOException: CreateProcess: "C:\Program Files\Java \jdk1.5.0_11\jre\bin\java.exe" -Xmx256M -classpath "C:\Program Files \Common Files\eclipse\workspace\development\src;C:\Program Files \Common Files\eclipse\workspace\development\lib\build \hbBuildSupport.jar;C:\Program Files\Common Files\eclipse\workspace \development\lib\db\hibernate\ehcache.jar;C:\Program Files\Common Files \eclipse\workspace\development\lib\db\hibernate\hibernate- annotations.jar;C:\Program Files\Common Files\eclipse\workspace \development\lib\db\hibernate\hibernate-commons-annotations.jar;C: \Program Files\Common Files\eclipse\workspace\development\lib\db \hibernate\hibernate-entitymanager.jar;C:\Program Files\Common Files \eclipse\workspace\development\lib\db\hibernate\hibernate-tools.jar;C: \Program Files\Common Files\eclipse\workspace\development\lib\db \hibernate\hibernate-validator.jar;C:\Program Files\Common Files \eclipse\workspace\development\lib\db\hibernate\hibernate3.jar;C: \Program Files\Common Files\eclipse\workspace\development\lib\db \hibernate\javassi� It seems that something at somepoint of the compilation, the library paths are getting truncated. Could this be due to some character limit on CreateProcess? This CreateProcess command string gets to be only about 1024 , which seems like a small limit. Is there anyway to increase this limit?

Re: Expire an idle session
Hi Hez,
As Tony said, setting the session time out in the server would be the better
way.
I guess that you are trying to set this timeout in client side because you
let individual users configure their session time out period. If that is the
case, then you will have to follow the way that have mentioned.
HTH,
Kamal

Re: Don't obfuscate Java methods when passing instance to JavaScript
This is from memory, but in general, I thing it should work:
package com.mypackage;
public class Foo
{
private String message;
public Foo(String message)
{
this.message = message;
}
public void sayHello()
{
Window.alert("Hello " + message);
}
public static native void export() /*-{
function Foo_Type(message)
{
this.instance = @com.mypackage.Foo::new(Ljava/lang/String;)
(message);
}
Foo_Type.prototype.sayHello = function
{ this.instan...@com.mypackage.foo::sayHello()(); }
$wnd.Foo = Foo_Type;
}-*/;
}
Call Foo.export() from your onModuleLoad()
JavaScript should then be able to do:
var f = new Foo("Dean");
f.sayHello();

It seems other browsers keep track of the hash and use it on the final (i.e. after all redirections at the lower, HTTP, level have taken place) resource (in case it's the very same resource that were at the original URL and was jut moved around), while IE considers the hash part of the URL.

Re: Need fix for GWT 1.6 Jars in Maven Repo
Hi Salvador,
Sorry for answering so late, I didn't check this thread in a while.
The code you posted in the pastebin is expired, but here is how we
declared our GWT dependencies:
com.google.gwt
gwt-servlet
${gwtVersion}
compile
com.google.gwt
gwt-user
${gwtVersion}
provided
I was using the googlecode GWT-Maven plug-in (not the codehaus one),
and the issue I had was that Maven saw the javax.servlet.*.java had a
more recent timestamp than the javax.servlet.*.class, and thus thought
it was a good idea to re-compile them and add them to our war (in /WEB-
INF/classes/).
Our war's lib folder did not contain gwt-user.jar, only gwt-
server.jar, since gwt-user's dependency was provided. The conflict was
thus caused by these additional classes in WEB-INF/classes/.
The GWT team fixed my issue by having the same timestamp for the .java
and .class files in javax/servlet. It seems that the fix didn't work
for Cyril and maybe some other people (where Maven re-compiles the
source files even though their timestamp is correct), but I don't know
if it is due to differences between the googlecode and codehaus gwt
maven plugins, or if it is due to some specific maven configuration.
Hope this helps!
Have a nice day,
-eneveu
