GWT Mail sample using Spring Dreamsource ORM
I modified the GWT mail sample distributed with GWT. The mail sample can retrieve emails from HSQLDB and update contacts in the database. I use the following features - Spring IOC and Spring AOP transaction, Dreamsource ORM. You can lauch a href=http://www.leeonsoft.com/mail/ Mail.htmlthis application/a. The source code is available from http://dreamsource-orm.googlecode.com/files/mail_1.0.0_04202009.jar. You need Dreamsource ORM source code that is also available from http://dreamsource-orm.googlecode.com/files/dreamsource2_0_1_04202009_GWT_src.jar. Dreamsource ORM is making big difference in developing GWT application. Any feedback is welcome.

Re: A native GWT chart library?
Hi I currently use the GWTCanvas, for creating pies. It works very well. The code I can just copy paste from swing/awt code examples because the GWTCanvas api is very much like the normal jdk canvas. And you can your self attach mouse listeners etc on the pie so it becomes interactive, with the rest of the page. So for pies it is well suited. However I have not cracked the nutt with respect to drawing text in the canvas, last time I checked the versiondid not support drawString(...) method, so that was a no go. /Flemming ps: if you want I can attach the code.

JsParserException: invalid label
Hi there!
Can anyone help me with the error mentioned above?
I try to make an interface to JavaScript so I can call a function. My
Java code looks like that:
public void onModuleLoad() {
setShowTrigger(this);
}
public native void setShowTrigger(Index x)/*-{
$wnd.showIndex = function () {
website.client.Index::runApp()();
};
}-*/;
public void runApp() {
Window.alert(I am a GWT function);
}
As soon as I add the method setShowTrigger it crashes with the
following error. Do I have to include a special library? Or is there
another way to call a GWT function from the HTML part?

Yes, my sentence above I meant in that way, that I don't know how the user experience will be if you try out what I suggest. An enabled checkbox that reset that value after clicking might look very ugly because you will actually be able to change the value (i.e. the checkbox will be empty or set) but it will jump back to the previous value. So this might be very ugly. As well you should check if the listener got called if you set the value by focusing the checkbox using your keyboard and pressing the space-key.

Re: Automatic logout feature
If you're using Spring, you might want to take a look at Spring Security. It handles session management and role based security for you. You can then couple that with a check against the server side if the user's session is still valid. You can either do this with a Timer (if you want to time them out right away) or build it into your page/screen changing system. We do the latter using a history management filter whereby history changes go through a number of filters before arriving at the correct handler. If the user check filter catches the user isn't logged in, we show them the login screen. -- Arthur Kalmenson On Mon, Apr 20, 2009 at 9:06 AM, Mark cattaba...@gmail.com wrote: Well appreciated comrades The intention was never to drive you to write code but to give me a peek for i am raw in this field I have gotten that and i appreciate Thank you again.

Re: GWT Session
Hey Professor Vagner,
Why not using google project hosting or http://pastebin.com to post
your code examples and simply link to them in your posts ? It's nearly
impossible to read code in a font face that's not monospaced (not to
mention indentation and syntax highlighting).
I'm sure your code snippets would be much more appreciated that way.
At least I wouldn't have an instantaneous gut reaction to dismiss them
because of the utter torture of reading them without any syntax
highlighting and correct indentation.
Thanks for contributing to the community,
Salvador

SessionId is not part of GWT. It's some class he wrote. Can't help you

All I was saying is that the RPC calls he does are GWT 1.5 style - 1.6 has a
much cleaner way of doing it.

hello Vagner,
This is very good example..
When I started implementing the same, it is asking me for SessionId.
could you tell me from where you are refering this one. It would be
helpful to me if you put it over here.
Also, is it possible to reference/create a user define data/object on
client side?
Thanks in advance.

.gwt-DecoratorPanel .topLeft {
background: url(images/corner.png) no-repeat 0px 0px;
-background: url(images/corner_ie6.png) no-repeat 0px 0px;

My best guess from the filename (corner_ie6.png), is that the second will be
used by IE.
I opened corner.png and corner_ie6.png, but both images look the same to me.
What is the reason to have the background and -background selector?

Re: I installed the GEP and now...
Hey Ian, Thanks for the information. Responses inline: On Mon, Apr 20, 2009 at 7:26 PM, Ian Bambury ianbamb...@gmail.com wrote: Hi Rajeev, Thanks for the response. When you tried to install it again, did you install it in a clean version of Eclipse, or was it the version that you were using with all the failed installation attempts? It may be the case that you need to uninstall the plugin, and then try to reinstall it. Preferably, if possible, start with a clean install of Eclipse and a clean workspace, and try and install again (but follow the instructions in the FAQ entry mentioned above - they will greatly speed up the install process). It was a clean, new Eclipse installation. I was only trying to install the GEP and the GWT SDK, nothing else. Eclipse locked up showing 31% completed, nothing moving except the progress indicator (no actual progress, just animation). Cancel didn't do anything (except disable the cancel button) and after some time - in the region of 30 minutes - I went back and nothing had changed. There was no option but to kill it in task manager. This is definitely odd. It must have been some network problem, but I'm not sure which side it occurred on. One thing I do know is that Eclipse does not fail gracefully in such situations. Do you remember exactly what text was in the dialog at the time? Was it saying something like computing requirements and dependencies, or was it saying downloading, or maybe installing? The second attempt of the current series, it installed in 30 seconds or so. I'm not sure exactly, I was watching TV, but it wasn't long at all. Now if I go to Software Updates, Installed Software shows the GEP and GWT SDK as installed. Available Software shows the plugin (but no install option is available) and the AppEngine SDK. Does Installed Software also show the plugin as installed? Available Software should really not have any of the components as installable, if they've already been installed (unless you have the Include items that have already been installed checkbox checked). The IDE doesn't have the two icons I had when it finally installed last time, ordinary menu options are also not there (in File|New, or right-clicking a project - nothing new) Try going to Window - Reset Perspective (or, on the Mac, Eclipse - Reset Perspective). Does that help? Also, do you see any errors reported in the error log? Go to Window - Show View - Error Log (or, on the Mac, Eclipse - Show View - Error Log) to display the error log view. I'm sorry that you had to go through all of this. Bad things can happen when components are not properly installed, as you experienced. This should not be the normal experience at all. Is your project/Eclipse back in a working state? If not, let me know and I'll help you to get it back to normal. Yes, despite unchecking the project as a GWT one in the GEP options, and after the uninstall apparently working OK, there were still GEP changes in there stopping the project working. Having sorted that out, as I said, context assist didn't know about GWT classes. That is now fixed, too. I tried the -clean option (thanks Isaac) but unfortunately it didn't make any difference. That was after restarting Eclipse, then rebooting the machine. I'm not particularly worried about getting it working. As I said, I was only re-installing it in order to answer the questions I was asked before. Thanks for going through all of this in order to give us some useful information. We appreciate it.

Re: JsParserException: invalid label
Hey !
Please don't post multiple times your questions (http://
groups.google.com/group/Google-Web-Toolkit/msg/0675da9d966c77d7), be
patient and maybe somebody will reply ;)
So about your popup thing, why use JSNI when you can just do
public void onModuleLoad() {
Window.alert(This is a GWT function)
}
Maybe you're simplifying your code to show us what you're trying to
accomplish, but if you really just want an alert, don't go the JSNI
way.

help? It works without any error messages but the GWT function is
never executed.

/**
* Entry point classes define codeonModuleLoad()/code.

Re: GWT on FreeBSD
I don't have a FreeBSD box handy, but this seems like it'd be workable. Good call about replacing the SWT binaries with your native ones. Would it help, do you think, to compile GWT from source?

Re: Module without EntryPoint - How to compile?
Hey Ben, Glad that all is well now. On Mon, Apr 20, 2009 at 6:16 PM, Ben FS ben.su...@gmail.com wrote: To exclude non-entry point modules from being included during a Hosted Mode launch or a GWT Compilation, right-click on your project, and select Google Web Toolkit Settings. From there, you can remove the common module from the list of entry point modules. This should fix the problems that you're experiencing in Hosted mode. This has indeed fixed the main problem. The popup error no longer appears and the page opens correctly in the external browser. However, the hosted mode log still shows the error regarding the module without EntryPoint. So, no problem for me, but somewhere something is still throwing an error. Can you follow the instructions here to view the set of Available Modules in the launch configuration that you're executing: http://code.google.com/eclipse/docs/running_and_debugging.html Do you see the non-entry point module in the list? If so, can you hit Restore Defaults, run the launch configuration, and see if that fixes your problem? To perform a compile from the IDE, follow the instructions here: http://code.google.com/eclipse/docs/gwt_compile.html I also tried this, and it worked as well for me.

Re: Creating GWT application
If you can't get Eclipse's install mechanism working, here's how you can install the plugin manually in Eclipse 3.3: Download the following file and place it in a temporary directory: http://dl.google.com/eclipse/plugin/3.3/site.xml Now, download the following into a directory called *features*, underneath your temporary directory: http://dl.google.com/eclipse/plugin/3.3/features/com.google.appengine.eclipse.sdkbundle.e33.feature_1.2.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/features/com.google.gdt.eclipse.suite.e33.feature_1.0.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/features/com.google.gwt.eclipse.sdkbundle.e33.feature_1.6.4.v200904062254.jar Finally, download the following into a directory called *plugins*, underneath your temporary directory: http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.appengine.eclipse.core_1.0.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.appengine.eclipse.sdkbundle_1.2.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gdt.eclipse.core_1.0.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gdt.eclipse.suite_1.0.0.v200904062254.jar http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gwt.eclipse.core_1.0.0.v200904062254.jar If on linux: http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gwt.eclipse.sdkbundle.linux_1.6.4.v200904062254.jar If on mac: http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gwt.eclipse.sdkbundle.macosx_1.6.4.v200904062254.jar If on windows: http://dl.google.com/eclipse/plugin/3.3/plugins/com.google.gwt.eclipse.sdkbundle.win32_1.6.4.v200904062254.jar Now, go into Eclipse, and set up a local update site, and point it to the temporary directory that you created.

Re: Problem in downloading Google Plugin for Eclipse
Actually, I made a mistake in the install instructions: Alternatively, you can just rename the temporary directory to eclipse, remove the site.xml file, and copy this directory under your Eclipseinstall's *dropins* directory. This is not correct. If you want to install via this mechanism, you first need to go into the features directory under the temporary directory that you created, and unjar all of the jar files in there. Then you can go ahead an install via the dropins mechanism. Note that this only needs to be done if installing via the dropins mechanism - if you're installing using the local update site technique, then you shouldn't unjar the feature jars.

Re: Why am I seeing: GWTCompiler is deprecated and will be removed in a future release?
The beauty of the new Compiler and HostedMode classes is that they are pretty verbose if you mess up the options (use no longer existent options).

Re: How to use newer version of Jetty for Hosted Mode server?
Hey Tim, In order to make this work, you can either implement a ServletContainerLauncher of your own, and use the -server option with the HostedMode entry point, as Salvador suggest. More info on ServletContainerLaunchers can be found here: http://code.google.com/p/google-web-toolkit/source/browse/releases/1.6/dev/core/src/com/google/gwt/core/ext/ServletContainerLauncher.java http://code.google.com/p/google-web-toolkit/source/browse/releases/1.6/dev/core/src/com/google/gwt/core/ext/ServletContainer.java However, the easiest thing to do is probably to start with GWT's existing launcher for Jetty and modify it to suit your needs. This is the launcher that GWT is using to start up Jetty: http://code.google.com/p/google-web-toolkit/source/browse/releases/1.6/dev/core/src/com/google/gwt/dev/shell/jetty/JettyLauncher.java You'll have to modify your launch classpath to put your version of Jetty higher up on the classpath than the GWT SDK. You'll also have to put your version of JettyLauncher higher on the classpath as well. Rajeev 2009/4/21 Salvador Diaz diaz.salva...@gmail.com use -noserver or -server ?

Re: Having a Problem with GWT XMLparser
I have noticed that pretty xml causes fits, but Document doc = XMLParser.parse(xml); XMLParser.removeWhitespace(doc); seems to clear it up.

TextBox.setName() and Java Http Servlet request.parameter(arg)
Hello everyone I'm writing about this problem i have found, when i try to send to a plain Java servlet a file using FileUpload and some others parameters stored in some textboxes. I set the form to Multipart encoding, 'cause i have to upload a file (and it works fine), i set the method to POST, but in the java servlet when i try to retrieve the data it shows me always a null pointer, even if i try to change to GET, or by using urlencoded, the request.getparameter(nameofmyformfield) is always null. I tried also using others method like getattribute or getattributenames and i always get null pointer. The other way i try to get the data is by using the ListFileItem in which the java servlet stores the uploaded file, but it has only one element (the file itself) and nothing else. To test the servlet class and the gwt itself, i also tried to make a gwt program that send with a post/get in urlencoded, but the methods above always return a null value. Any help will be appreciated. - Nickelnext --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: I installed the GEP and now...
Hey Ian, Just thought I'd mention that I tried something to repro your problem. Our plugin does not work if you're running Eclipse under a pre-1.5 JVM, and some of the symptoms that we've seen is that the plugin icons/menu contributions will not show up. However, we've only seen this when we've been using Eclipse's dev environment to debug the plugin. I tried to repro this by running clean Eclipse 3.3 and Eclipse 3.4 installs with a 1.4 JVM, but Eclipse did not even run - it threw up an error dialog indicating that a 1.5+ JVM is required. So, it looks like a pre-1.5 JVM cannot cause this sort of problem with the plugin out in the field.

When you tried to install it again, did you install it in a clean version of Eclipse, or was it the version that you were using with all the failed installation attempts? It may be the case that you need to uninstall the plugin, and then try to reinstall it. Preferably, if possible, start with a clean install of Eclipse and a clean workspace, and try and install again (but follow the instructions in the FAQ entry mentioned above - they will greatly speed up the install process). It was a clean, new Eclipse installation. I was only trying to install the GEP and the GWT SDK, nothing else. Eclipse locked up showing 31% completed, nothing moving except the progress indicator (no actual progress, just animation). Cancel didn't do anything (except disable the cancel button) and after some time - in the region of 30 minutes - I went back and nothing had changed. There was no option but to kill it in task manager. This is definitely odd. It must have been some network problem, but I'm not sure which side it occurred on. One thing I do know is that Eclipse does not fail gracefully in such situations. Do you remember exactly what text was in the dialog at the time? Was it saying something like computing requirements and dependencies, or was it saying downloading, or maybe installing? The second attempt of the current series, it installed in 30 seconds or so. I'm not sure exactly, I was watching TV, but it wasn't long at all. Now if I go to Software Updates, Installed Software shows the GEP and GWT SDK as installed. Available Software shows the plugin (but no install option is available) and the AppEngine SDK. Does Installed Software also show the plugin as installed? Available Software should really not have any of the components as installable, if they've already been installed (unless you have the Include items that have already been installed checkbox checked). The IDE doesn't have the two icons I had when it finally installed last time, ordinary menu options are also not there (in File|New, or right-clicking a project - nothing new) Try going to Window - Reset Perspective (or, on the Mac, Eclipse - Reset Perspective). Does that help? Also, do you see any errors reported in the error log? Go to Window - Show View - Error Log (or, on the Mac, Eclipse - Show View - Error Log) to display the error log view. I'm sorry that you had to go through all of this. Bad things can happen when components are not properly installed, as you experienced. This should not be the normal experience at all. Is your project/Eclipse back in a working state? If not, let me know and I'll help you to get it back to normal. Yes, despite unchecking the project as a GWT one in the GEP options, and after the uninstall apparently working OK, there were still GEP changes in there stopping the project working. Having sorted that out, as I said, context assist didn't know about GWT classes. That is now fixed, too. I tried the -clean option (thanks Isaac) but unfortunately it didn't make any difference. That was after restarting Eclipse, then rebooting the machine. I'm not particularly worried about getting it working. As I said, I was only re-installing it in order to answer the questions I was asked before. Thanks for going through all of this in order to give us some useful information. We appreciate it.

List of Usable Java Packages?
Hi there! I'm sure this is a pretty naive question, but is there a list somewhere of what java objects I can ( or cannot ) use? I tried creating a connection to an oracle instance in the onModuleLoad function, in hopes of using the resultset to populate basic datasets for gwt, but apparently i was wrong. I stumbled upon some of the google-gears gwt source code, and they are using various classes that instantiate custom JavascriptObject(*) classes, which leads me to believe I'm totally lost. I just want to use my java data structures :( Besides that, very pleased!

Facebook XFBML in GWT Hosted Mode?
Hi Friends, I am trying to develop Facebook Connect application with GWT. I tried to have XFBML like fb:name /fb:name in a HTML control.

Insert Element into DOM and receive click events?
I'd like to dynamically insert a Widget into/next to a single
TreeItem, whenever a TreeItem is selected, but event handlers on the
Widget never fire when I do this.
My approach so far: I dynamically manipulate the DOM of a single
TreeItem, when a selection event occurs. First I insert a DIV sibling,
and then I insert the Widget into that placeholder. Something like
this:
Button b = new Button(Click me, new ClickHandler() {
public void onClick(ClickEvent event) { Window.alert(I was
clicked!); }
});
Element itemDiv = treeItem.getElement(); // the TreeItem's underlying
element
Element spanEdit = DOM.createSpan();// a container, perhaps this
is not necessary
DOM.appendChild(itemDiv, spanEdit);
DOM.appendChild(spanEdit, b.getElement());
The button appears in the TreeItem when the TreeItem is selected, but
I am not able to generate any click events when I try to click on the
button with the mouse. I've also tried replacing the Button with
direct HTML, as follows:
HTML h = new HTML(a href='javascript:alert();'Click me for alert/
a);
Once inserted into the TreeItem, on mouseover the browser status bar
shows the link target, but clicking on it does not generate a popup.
My sense is that I need to do something else when I insert an Element
into the DOM, to ensure that it participates in the event handling
correctly. Yes? What else do I need to do?
Perhaps the Tree's SelectionHandler is interfering - a mousedown on
anything within a tree's node triggers a selection event and no other
events are processed?
Note: This used to work for me, using GWT 1.4.62, but even then only
when the inserted Widget was a Button (for all other Widget's that I
tried, the click event never reached the declared handler).
Note: I would prefer to do all this without manipulating the DOM, but
there is a bug in TreeItem, since early version of GWT, that prohibits
me from dynamically removing and later replacing the TreeItem's
content.

Hooking Spring 2.5.6 and GWT 1.6 - getServletContext returns N
Hi,
I am trying to use a GWT service with Spring.
I am using DispatcherServlet from Spring, GWTHandler and my service is
defined as a bean in a mywebapp-servlet.xml file.
I have also beans intialized at startup with ContextLoadListener.

it. In that case I have a NullPointerException. As a consequence I can
not make reference o my other beans from my service.

Re: List of Usable Java Packages?
GWT only implements a subset of Java: http://code.google.com/p/google-web-toolkit-doc-1-5/wiki/RefJreEmulation You should also think of it as client side web code (after all it gets compiled to JavaScript) as such you wouldn't normally be able to connect to a database directly - you'd go through the server which connects.

Re: I installed the GEP and now...
Hey Ian, If you're ok with reinstalling Eclipse, this is what I'd suggest: 1) Blow away your old version of Eclipse, and install a completely clean version of Eclipse 2) Start it up with a completely new workspace 3) Try to install the plugin as before, *BUT make sure you follow the instructions in this FAQ entry before hitting the install button: http://code.google.com/eclipse/docs/faq.html#longinstall* That should get you going, and completely past the hangs that happen in Eclipse 3.4 in the Computing Requirements and Dependencies step of the install process. If you're not ok with reinstalling Eclipse, let me know, and we can try and work through removing all the old, corrupted artifacts of the failed plugin installs so that you can install the plugin from scratch.

Our plugin does not work if you're running Eclipse under a pre-1.5 JVM, and some of the symptoms that we've seen is that the plugin icons/menu contributions will not show up. However, we've only seen this when we've been using Eclipse's dev environment to debug the plugin. I tried to repro this by running clean Eclipse 3.3 and Eclipse 3.4 installs with a 1.4 JVM, but Eclipse did not even run - it threw up an error dialog indicating that a 1.5+ JVM is required. So, it looks like a pre-1.5 JVM cannot cause this sort of problem with the plugin out in the field.

anchor.addClickHandler(new ClickHandler()
{
public void onClick(ClickEvent event)
{
//do something
}
});
I get a new blank browser window popup and and several warnings in the

Any ideas what's going on?
The click handler seems to still get fired.

serialization to history - bad idea?
Do you think is it a bad idea to use SerializationStreamWriter and SerializationStreamReader to write an object's state to the history? It seems like it would be a more convenient way to go than for me to try to write my own methods for doing this. I guess it could be a problem if I blow past the URL length limit but I suppose that is a possibility with my own serialization schemes too.

HtmlUnit 2.5, a headless java browser, released
A new release of the Open Source java GUI-Less browser is available, which allows high-level manipulation of web pages, such as filling forms, clicking links, accessing attributes and values of specific elements within the pages, you do not have to create lower-level requests of TCP/IP or HTTP, but just getPage(url), find a hyperlink, click() and you have all the HTML, JavaScript, and Ajax are automatically processed. The most common use of HtmlUnit is test automation of web pages (even with complex JavaScript libraries, like Google Web Toolkit and jQuery), but sometimes it can be used for web scraping, or downloading website content. The main enhancements of this release: - Improved JavaScript support, particularly full support for MooTools, adding to already supported Google Web Toolkit 1.5/1.6, jQuery, Mochikit and Sarissa - Repackaged Rhino classes to allow the use of HtmlUnit and a regular Rhino version in the same project - Support all HTML elements - Experimental WebClient.waitForBackgroundJavaScript() and WebClient.waitForBackgroundJavaScriptStartingBefore() for simple, fast and deterministic AJAX testing - Reworked handling of background JavaScript tasks using Java 5 executors - And as usual, various bug fixes You can find more information in the official website (http:// htmlunit.sourceforge.net/), the development team is looking forward to getting your feedback. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT server side access to web service from another server
Hi,
I'm creating a GWT (1.6) app from scratch and I have done the current
thing:
User Web Browser (1)
GWT client-side
|
(gwt rpc)
V
GWT server-side (2)
|
(JAX ws rpc)
V
another server (3)
everything's done :
- the gwt rpc between (1) and (2)
- the web service on (3) is done with JAX-WS wsgen
- the client web service on (2) is done with JAX-WS wsimport
so everything's ok BUT :
the client web service class located on (2) uses the JAX-WS annotation
@WebServiceRef to populate the 'service' static var and the value is
'null'.
The workaround : to comment @WebServiceRef and uncomment (a) - see
code below : manually instantiate the generated artifact (by
wsimport). This is OK.
but why is it not using the annotation @WebServiceRef with GWT?
here is the class :
__
package fr.server.ws_client;
import javax.xml.ws.WebServiceRef;
import fr.server.ws_client.gen.Info;
import fr.server.ws_client.gen.InfoService;
public class InfoClient {
@WebServiceRef(wsdlLocation=http://localhost:9091/Info?wsdl;) static
InfoService service;
public static String getServerVersion() {
String server_version;
try {
server_version = InfoClient / getServerVersion : try;
InfoClient client = new InfoClient();
server_version = client.doGetServerVersion();
} catch (Exception e) {
server_version = InfoClient / getServerVersion :
catch;
e.printStackTrace();
}
return server_version;
}
public String doGetServerVersion() {
try {
//(a) InfoService service = new InfoService();
Info port = service.getInfoPort();
return port.getServerVersion();
} catch (Exception e) {
e.printStackTrace();
return InfoClient / doGetServerVersion : catch;
}
}
}

popup on an GWT HTML field
Hi folks! Only one question left and my project should be completed! :-) I'd like to print out HTML text (content). But only a few words should have a special function (popup on click). How would you do that? Unfortunately I couldn't find any tutorials. I managed to print HTML code and inplement my popup function with JS (onclick =). But the content is dynamic so I should find another way with GWT. My way of creating the HTML code: new HTML(bHello world!/b); -- So if you click on world, a new popup should open (class already exists and is working) Do you have any ideas? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 1.6.4 - Intellij 8.1 - Hosted mode via application start.
Hi all. I'm using Intelli-j 8.1 to build my GWT 1.6.4 application. I realize that Intell-j's GWT plugin isn't suited for 1.6.4 just yet. Avoiding the plugin I'm attemping to run in Hosted mode by running the app as a normal Java application. Main class: com.google.gwt.dev.HostedMode VM params: -Xmx500M program params: -startupUrl /enroll/default.html com.vincent.gwtapps.webApplicationForm.WebEnroll working dir: C:\work\jv_websales\WebApplicationForm\current_branch\out \exploded\ When I deploy the application with my own ant scripts the application loads fine under it's own tomcat instance. The only difference I see between my ant war and the exploded intelli- j war directory is that the hex js files aren't there, for example (644251F628D38C39522797805967F32D.cache.html). The directory only has the 2 files, clear.cache.gif, hosted.html, and webenroll.nocache.js. Does hosted mode need those files, or are they generated by the GWT hosted mode browser? If they need it, I suppose I could run an ant task to generate them, prior to running the application.

single row in PagingScrollTable does not have proper height in IE7
I'm using the PagingScrollTable from GWT Incubator version 1.5- Dec_28. When I have only a single row in the table, the table height shrinks such that the row is no longer visible. If I add more rows, everything is properly sized.It seems as if maybe the height of the horizontal scrollbar is not being taken into account, or some other off by one error is happening. My current workaround is to add a stylename with an explicit height: 30px to the row using RowFormatter. This is kind of a hack, as the height of my rows varies with the data contained.

Even it that weren't the case, surely progress would have increased by at least 1 percent when left for 8 or 9 hours overnight? Even if you're just installing the plugin without the SDK - the instructions in that link still apply. Whenever you install ANY new plugin on Eclipse 3.4, the behavior described in that FAQ entry will occur. The code for computing the requirements/dependencies for a plugin in Eclipse 3.4 is riddled with problems. It is also brittle in the sense that it can get hung up/stuck while attempting to connect to other update sites in an effort to resolve dependencies. I think that's what happened in your case - it basically got stuck - that's why progress did not increase. But if I get a break where I don't need to use Eclipse for a while, I'll re-install it and try from scratch again. Thanks. If you keep running to problems, see the info mentioned here on how to do a manual install of the plugin: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/f127367d8a578013/dbbd67c1e79b03e3 Ian http://examples.roughian.com 2009/4/21 Rajeev Dayal rda...@google.com Hey Ian, If you're ok with reinstalling Eclipse, this is what I'd suggest: 1) Blow away your old version of Eclipse, and install a completely clean version of Eclipse 2) Start it up with a completely new workspace 3) Try to install the plugin as before, *BUT make sure you follow the instructions in this FAQ entry before hitting the install button: http://code.google.com/eclipse/docs/faq.html#longinstall* That should get you going, and completely past the hangs that happen in Eclipse 3.4 in the Computing Requirements and Dependencies step of the install process. If you're not ok with reinstalling Eclipse, let me know, and we can try and work through removing all the old, corrupted artifacts of the failed plugin installs so that you can install the plugin from scratch.

Available Software shows the plugin (but no install option is available) and the AppEngine SDK, but if there is another way to check, just let me know - Help | About | Plug-in details doesn't show it. It locked up during computing requirements and dependencies The only errors to do with Google showing in the log are from failed compiles back when I tried to use the GEP the first time. I've reset the perspective - nothing happened except that I had to put it back how I like it :-) (only takes a moment) I'm quite happy to play about if it's any use, but apart from repeatedly uninstalling and re-installing, I'm not too sure what to do next.

Re: A native GWT chart library?
Thanks all for your help. You're welcome! Ben, I looked at the links you gave me, a lot of interesting things but no client-site library that fits my need. For what it's worth, I too would really like a client-side library - mainly so that I can do lots of quick, small updates without much latency. The quality just wasn't adequate for the client-side libraries that I tried, so I switched back to a server-side library. In my case, so far there has been no noticeable increase in latency: you may wish to reconsider your need for a client-side solution, and at least try it with an easy server-side solution (aka Google Chart API or Eastwood) and see what your results are. Maybe you've already tried this, or have other good reasons for a client-side solution. So I think I'm gonna end up doing a wrapper for dojo chart. Sounds like a great project, and one that would be useful to many (including me). If you make progress on this, would you consider establishing a Google Code project? Best of luck, Ben.

Re: Playing audio files in GWT
I'm going to provide the same response for this and your similar question about video (http://groups.google.com/group/Google-Web- Toolkit/browse_frm/thread/9276cb86ebc94ffa?hl=en), as the two questions are related. You can embed audio and video in GWT applications, but, in general, GWT needs to invoke a player (QuickTime, Flash) in order to play media. There are various ways to do this, depending on your needs. For instance, if you can assume the presence of QuickTime, you can embed a player like this: http://support.apple.com/kb/TA26485?viewlocale=en_US My company actually did this for a recent project until we discovered that QuickTime does not work properly on Windows 64, at which point we switched to Flash (and the JW FLV player, http://www.longtailvideo.com/players/jw-flv-player/) which we embed with the swfobject javascript library (http:// code.google.com/p/swfobject/) that also comes packaged with JW FLV. We invoke this through GWT with JSNI. There seem to be a number of open source wrappers around the various players too, if you want to go that route. I only can comment on gwt- voices, which works well, but which we could not use as we needed pause and seek support.

[gwt-contrib] subtree logging for problems
Here's the promised follow-on to my earlier, fixing the subtype logging to be a subtree logger. I'm still bothered by the multiple entries for E extends java.lang.Object, but I'm not sure which is the better way to fix it... I think I would like to change JType constructors and/or .equals, to generalize to e.g. id1 extends java.lang.Object or id1 extends Mapid2 extends KeyType, id3 implements ValType, but I'm not sure how such a change might impact other uses of JType and children elsewhere... I would like to think it was beneficial. The other, more localized approach would be to change the TIC map key from JClassType to String, and to do the identifier-abstraction as types were stringified in STOB, only.

[gwt-contrib] [google-web-toolkit commit] r5266 - Fixed a bug in HandlerManager where removing the last handler of a given EventType twice ...
Author: jlaba...@google.com
Date: Tue Apr 21 10:27:39 2009
New Revision: 5266
Modified:
trunk/user/src/com/google/gwt/event/shared/HandlerManager.java
trunk/user/test/com/google/gwt/event/shared/HandlerManagerTest.java
Log:
Fixed a bug in HandlerManager where removing the last handler of a given
EventType twice would result in an NPE because we assume that the list of
event handlers is not null. Now, this results in an AssertionError.

your code, both handwritten and generated, in the debugger. This avoids
tricky or confusing situations wherein the source code you see appears to be
doing something different than the bytecode that's running. It seems good to
avoid that kind of dichotomy, on the principle that
straightforward-though-verbose is generally better than fancy-but-confusing.

and that support is implemented at a very deep level. Also, JSOs are
intended to be among only a very few magic things in GWT (basically, JSNI,

ensure that JSOs worked according to a fixed set of rules that are not hard
to comply with, even if people don't fully understand why the implementation

This requires my model bean to support PropertyChangeListeners. As I'm lazy

I can get this to work today if my model Bean is created using GWT.create(),

I really think Guice-style dependency injection is the way to go to
solve this problem, rather than trying to emulate Java
Proxies/Classloader in the compiler. If you use Guice/Gin, then in Gin
you can inject GWT.create-d versions, and in JUnit-mode, you can use
regular Guice injection. The code use is 99% between GWT and non-GWT
versions test versions, with the exception of the
Guice-config/Injector creation.
Because of the way Gin works transitively, you only need a single

[gwt-contrib] Re: Java source transformation
Interesting question. Gin auto-creates RPC interfaces as well, for
example, if you have:
public interface MyFoo extends Ginjector {
MyServiceAsync getService();
}
then Gin implicitly looks for MyService.class and invokes
GWT.create(MyService.class) when calling getService(). Since Gin is
handling the creation, I'm not sure if it handles RPC methods with
classes have have @Inject annotations, but you could probably setup a
separate binding. The de-serialization logic in RPC is not likely to
allow Gin interception, since it apparently uses default constructors
to create classes, and what you want it to do is delegate the
construction to some injectable mechanism (e.g. to substitute your own
subclasses)
It doesn't sound impossible to make this work, and is probably easier
to get right than trying to make new Foo() interceptable by the
compiler. I would join the Gin groups and ask the guys there about it.

someLogger.log(setName(' + name + ') called);

As formulated above, this pattern doesn't compose well. But it might be
that we can forge a pattern like this into something everyone likes
eventually.

This makes unit testing more difficult as code that uses GWT.create
cannot run in classic jUnit. It would be great to have the compiler
use
generator-extended classes even when created using the standard new
keyword.
Thanks a lot for the explanation.

LGTM. There's a typo in ProblemReport: accessir. -Lex On 4/21/09, Freeland Abbott fabb...@google.com wrote: Here's the promised follow-on to my earlier, fixing the subtype logging to be a subtree logger. I'm still bothered by the multiple entries for E extends java.lang.Object, but I'm not sure which is the better way to fix it... I think I would like to change JType constructors and/or .equals, to generalize to e.g. id1 extends java.lang.Object or id1 extends Mapid2 extends KeyType, id3 implements ValType, but I'm not sure how such a change might impact other uses of JType and children elsewhere... I would like to think it was beneficial. The other, more localized approach would be to change the TIC map key from JClassType to String, and to do the identifier-abstraction as types were stringified in STOB, only.

Hmm, but don't you normally send some kind of Model or domain object
over the wire and not something that would need to be injected with
dependencies by Gin?
I think what he's saying is that he might have an RPC method like this:
public interface MyService extends RemoteService {
MyBean getBean();
}
Now, MyBean does not implement interface X, but a generator/AOP
interceptor could make a subclass of MyBean that has interface X
implement. IIRC, GWT RPC just invokes the default constructor, so
there's no way to intercept this and substitute a replacement.
I think the other thing he might want to do is intercept client-side
UI classes and make them call addPropertyChangeListener() on a model
object based on certain invocations.

And Bruce, that's an interesting example. I was thinking how one would
implement AOP in GWT, perhaps it's not as hard as I originally
thought. Is there a way to extend this example to dynamically create
proxies for any class that'll be advised by some aspect?
Also, Nicolas, AFAIK, the GWT team (bobv) is working on a data binding
(and validation?) framework. I'm hoping something will hit the
incubator soon so we can all jump on board and help out. It'd
definitely have saved us thousands of lines of glue code ;).
P.S. Sorry about not writing up that how-to for GWTMockUtilities,
Bruce. I'll try to do it some time this week.
Best regards,

Interesting question. Gin auto-creates RPC interfaces as well, for
example, if you have:
public interface MyFoo extends Ginjector {
MyServiceAsync getService();
}
then Gin implicitly looks for MyService.class and invokes
GWT.create(MyService.class) when calling getService(). Since Gin is
handling the creation, I'm not sure if it handles RPC methods with
classes have have @Inject annotations, but you could probably setup a
separate binding. The de-serialization logic in RPC is not likely to
allow Gin interception, since it apparently uses default constructors
to create classes, and what you want it to do is delegate the
construction to some injectable mechanism (e.g. to substitute your own
subclasses)
It doesn't sound impossible to make this work, and is probably easier
to get right than trying to make new Foo() interceptable by the
compiler. I would join the Gin groups and ask the guys there about it.

How would this solve the use case data returned by RPC call ?
2009/4/21 Ray Cromwell cromwell...@gmail.com
I really think Guice-style dependency injection is the way to go to
solve this problem, rather than trying to emulate Java
Proxies/Classloader in the compiler. If you use Guice/Gin, then in Gin
you can inject GWT.create-d versions, and in JUnit-mode, you can use
regular Guice injection. The code use is 99% between GWT and non-GWT
versions test versions, with the exception of the
Guice-config/Injector creation.
Because of the way Gin works transitively, you only need a single
GWT.create() and this is isolated to your startup code while in your
JUnit version, you kick off a Guice-injected class instead.

If the generator enhanced class is used even when I use new Model()

Perhaps if you could distill down a more concrete example, it could get
