Re: embedded flash not displaying is IE7 on secured url but works fine when viewed with unsecured url
This just is a wild shot in the dark (I have very limited experience with Flash) but could it be a problem with the cache control headers in the response returned by the server? I've had a number of issues with IE (even IE7) + HTTPS that have resulted from this. See: http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/ImageBundle.html for a discussion of this issue for the GWT ImageBundle. See this: http://drupal.org/node/163298 for a discussion of the issue in a different context. Also this for downloading MSOffice files: http://support.microsoft.com/kb/316431 Basically, IE cannot download files successfully over HTTPS if caching is completely suppressed. Any of: Pragma: No-cache Cache-Control: no-cache in the response header will cause IE problems over HTTPS.

Re: Setting DataSource (JNDI) in GWT 1.6 (hosted mode - Jetty)
Hi
these are some things you have to do for setting a datasource:
1: put two additionnals jars in your classpath: jetty-naming-6.1.11.jar and
jetty-plus-6.1.11.jar to add some J2EE features on Jetty
2: change the startup JettyLauncher to your own custom JettyLauncher (works
with -server option ) : put this line in the tab Arguments eclipse setting
run program option:
-server com.myproject.MyCustomJettyLauncher
3 create your own MyCustomJettyLauncher : copy and past the JettyLauncher
to add some Configuration
private static String[] __dftConfigurationClasses =
{
org.mortbay.jetty.webapp.WebInfConfiguration, //
org.mortbay.jetty.plus.webapp.EnvConfiguration,//jetty-env
org.mortbay.jetty.plus.webapp.Configuration, //web.xml
org.mortbay.jetty.webapp.JettyWebXmlConfiguration,//jettyWeb
} ;
and at the end of the start() method call
wac.setConfigurationClasses(__dftConfigurationClasses);
WebAppContext wac = new WebAppContextWithReload(
appRootDir.getAbsolutePath(), /);
wac.setConfigurationClasses(__dftConfigurationClasses);
server.setHandler(wac);
server.start();
server.setStopAtShutdown(true);
4) edit a jetty-env.xml on the web-inf to specify a dataSource
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE Configure PUBLIC -//Mort Bay Consulting//DTD Configure//EN
http://jetty.mortbay.org/configure.dtd;
Configure class=org.mortbay.jetty.webapp.WebAppContext

Re: Synchornous GWT, how can i do that
Why do you need sync`ed method calls?
I think that you actually need a way to find out when a RPC call has
returned (either one of onSuccess / onFailed).
One way to go with this is to have a simple event system where events
are thrown when changes are made - these changes can be UI
modifications, RPC calls that arrived at client code, etc.
Class Event { String eventName, . }
Interface EventHandler { public void handleEvent (Event
event); .. }
Class EventDispatcher { here I have declared static members /
functions to register and dispatch incoming events }
Now all classes that need events would implement EventHandler.
Registering is done via constructor (or some other means).
We have implemented this system in a relatively large application and
it works like charm :)
Personally I have also used this paradigm for 2 personal projects, one
of them had no server-side and all reads were done with RequestBuilder
- everything went great
Of course, you can extend the system - what I am planning to do for
the library we are working on right now - to freeze the client code
until all conditions are satisfied.
Hope this helps,
Alex.

Re: Gilead 1.2.2
Hi,
First, thanks for the feedback : it is always nice to read that Gilead
is used and helps :)
About your issue, your analysis is right.
Possible workarounds would be :
- add @ServerOnly annotation on your statusName getter and setter
(Gilead will prevent it to be cloned and merged by beanlib)
- just add a null check condition in your statusName getter and
setter
Regards
Bruno

Hi Bruno - first off, thanks for all of your hard work. Your project is a
real life-saver, and we're using it extensively in our project.
I'd like to report a bug. I have not tested yet with gilead 1.2.2, but I'd
like to report it anyway.
Assume two classes:
public class Status {
Long id;
String name;
public Long getId() { ... }
public Long setId(Long id) { ... }
public String getName() { ... }
public Long setName(String name) { ... }
}
public class Ticket {
Status status;
public Status getStatus() { ... }
public Status setStatus(Status status) { ... }
public String getStatusName() { return getStatus().getName(); }
public String setStatusName(String name) { getStatus().setName(name); }
}
I've omitted the getters and setters for brevity, as I assume their contents
is well known. The problem occurs when serializing a Ticket instance. I
suspect that the problem lies in beanlib, though I wanted to consult you
first.
While serializing a Ticket, I receive a NullPointerException, while beanlib
tries to access the delegate method getStatusName in Ticket. I've come to
suspect, through debugging, that this happens since beanlib tries to copy
the statusName property (which does not exist) -before- copying the status
property. It'd be great if you could confirm my assumptions. For now, we've
prefixed all delegate methods with an underscore, to prevent beanlib from
recognizing them as property getters/setters.
Any thoughts?

Loading Images into GWT via MySQL
Hi,
I am new to loading images into GWT from MySQL and am abit lost on the
best way to do it.
I already have my image in the database. How do I retrieve it? I read
somewhere that it can just be stored as a String. Is this correct? So
my code on the server side would look like:
//Open database connection
dc.openConnection();
resultSet = dc.statement.executeQuery(SELECT CategoryImage FROM
itemcategory_table WHERE ItemType = 'Test');
while(resultSet.next()) {
String test = resultSet.getString(1);
}
dc.closeConnection();
Or have I got this completely wrong?
Next, I need to send this over to the client. What is the best way to
send an image over from the server to the client and how should it be
stored?
Any help on how to use images would be much appreciated!
Regards,
Jack

[gwt-incubator] problem working with glassPanel
Hello, Im building a big application that uses a lot of DialogBoxes,
so I decided to made a new class who extends DialogBox, showing both
DialogBox and glassPanel:
public class FadedDialogBox extends DialogBox {
private GlassPanel _gpFade;
public FadedDialogBox() {
super();
}
public FadedDialogBox(boolean autoHide, boolean modal) {
super(autoHide, modal);
}
public FadedDialogBox(boolean autoHide) {
super(autoHide);
}
@Override
public void center() {
_gpFade = new GlassPanel(false);
RootPanel.get().add(_gpFade, 0, 0);
super.center();
}
@Override
public void show() {
_gpFade = new GlassPanel(false);
RootPanel.get().add(_gpFade, 0, 0);
super.show();
}
@Override
public void hide() {
super.hide();
_gpFade.removeFromParent();
}
@Override
public void hide(boolean autoClosed) {
super.hide(autoClosed);
_gpFade.removeFromParent();
}
public String getFadeStyleName() {
return _gpFade.getStyleName();
}
public void setFadeStyleName(String style) {
_gpFade.setStyleName(style);
}
}
My EntryPoint testing class:
public class Menu implements EntryPoint {
public void onModuleLoad() {
Alert a = new Alert(probando, mucho);
a.show();
Alert b = new Alert(probando, mucho mas de lo que te crees);
b.show();
}
}
When I show just one FadedDialogBox everything works fine, the
problem appears when I show two or more, then, the glassPanel shows
over both DialogBoxes. I tried to fix it changing show() method:
RootPanel.get().add(_gpFade, 0, 0);
to
RootPanel.get().add(_gpFade);
But in this case everything looks worse, the second FadedDialogBox
turns background to black.
Any ideas or suggestions? I'm quite lost.
(Sorry for my bad english).

Re: Custom widget theme?
Sure, have a listener attached to a drop down box or menu or a button, some way for the user to select the theme. And on select use .removeStyleName(style) to remove the old style and .addStyleName (style) to add the new style name. If this is the only style you have applied to the Widget you could just use .setStyleName(style) to remove the old ones and use this new style.

Re: How to debug IE6 crash
I have the same problem now with IE6 (and seems to be also in IE7). Somehow, when you close the IE window, an error message pops up with the message that an error occured in the script of this page. Do I want to continue ? If you click yes, and go to that URL in a new window (since the previous window had to be closed in order to get the error message) the program continues to perform as expected. IE6 is the worst browser! (Maybe IE7 is even worse) Firefox, opera, Chrome, Safari all perform as expected. On Mar 12, 1:30 pm, Austen awconsta...@gmail.com wrote: Thanks Adam.

Re: Synchornous GWT, how can i do that
I've had the same problem some months ago.
I was developping a big application for a telco enterprise and most of
the application forms requiered loading several fields at the same
time during initialization.
For example, the create a route between servers form requieres to
load several drop-down lists: equipments, cards, business units,
market, ...
I don't want the user can work with the window until all the lists and
controls are loaded.
And I don't want to merge all services (getEquipments, getCards, ...)
in only one big service specific for this form.
It's easier to reuse code having atomic services.
I create a synchronizer class. During initialization I called
individual services (all calls are procesed in paralel and the total
time is slowest service time, not the sum).
I stored each asyncallback in the synchonizer, and finally create a
modal loading window. This modal window blocks the user but the
browser and the javascript engine aren't freezed.
When all the asyncalls are asnswered (succesfully or not), the
synchonizer close the modal loading window and the user can work the
full loaded form.
Hope it helps,

An example of the response is below: f8 � PKk�0 �/9�`�G ��0rXYz ] Q�f�~N�8 V���IH� �77��� k� ~�� I4�*3�� �,��A1�e_��-� ��*�vچ�xi�th�r +�'8F �C $�+��q��to ]�OP U��ڠ�2ş, �xJ� �'��F�˛7q�O��6�̵�J �h/�㍕� ռ��j��y Vb���O�^g��� ��� + -5��� �� 0 The server logs seem to show the server impl processing was completed sucessfully, but the localhost log shows the following stack trace: 12-Mar-2009 08:52:13 org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet default threw exception java.lang.IllegalStateException at org.apache.catalina.connector.ResponseFacade.sendError (ResponseFacade.java:404) at org.apache.catalina.servlets.DefaultServlet.serveResource (DefaultServlet.java:698) at org.apache.catalina.servlets.DefaultServlet.doGet (DefaultServlet.java:354) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter (ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter (ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke (StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke (StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke (StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke (ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke (StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service (CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11AprProcessor.process (Http11AprProcessor.java:833) at org.apache.coyote.http11.Http11AprProtocol $Http11ConnectionHandler.process(Http11AprProtocol.java:639) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java: 1285) at java.lang.Thread.run(Thread.java:619) At present I am still using gwt1.4, the inention is to upgrade to 1.5 shortly, and it's running against a tomcat 6 server. Is there anything obvious that I need to do to avoid these sorts of error, or methods to debug what has gone wrong between me completing the impl code processing and recieving the response on the client?

How to clear cache when there is change in code
Hi, I am using GWT for my project. But even if there is change in Code. I am not able to see any change. Or if server update GUI then also i am unable to see change.

GWT project with multiple pages
Hello! My question is perhaps not so relevant for Ajax applications, but for various reasons (including CMS), I would like to have a GWT application with multiple pages. What is the best way to do this? I have thought to have a GWT module for each page, but wonder if it is practical?

Show PDF with POST request
I have this: 1. [client] Call server from client via GWT-RPC 2. [server] Create map of the data and store them under the key 3. [server] Return key to the client 4. [client] Set Servlet URL with the key as query parameter in the com.google.gwt.user.client.ui.Frame instance 5. [server] In the Servlet, lookup for the data with exact key 6. [server] Generate PDF from data and return response (OutputStream) Is this possible in one way??? Explanation: I have large amounts of data on the client which must be send to the server, transform them (eg. XSL-FO), generate PDF, and return to the client (show PDF in widget, not in new window or something like that).

Re: Announcing GWT 1.6 Milestone 2
Hi All
I have an issue, I want to drag and drop the panel, It can be
horizontal or vertical or any other panel so that i can change it
property(like change its size), but it is not supporting for the
panels it is supporting for simple widgets like label,button,text box
and able to change it property also.
I try to do but facing issue.
Example:
AbsolutePanel ab=new AbsolutePanel();
Label LHP = new Label(HorizontalPanel);
LHP.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event) {
HorizontalPanel newHP = new HorizontalPanel();
newHP.setSize(50, 50); // on click panel size must be
fixed,user can change it size
newHP.setBorderWidth(2);// broder
ab.add(newHP); // adding panel to absolutePanel
dragController.makeDraggable(newHP);
// This listner is called when a panel is clicked
newHP.addMouseDownHandler(new MouseDownHandler(){
public void onMouseDown(MouseDownEvent event) {
// TODO Auto-generated method stub
Label proplab=new Label(Property Pallet);
}
});
Here addMouseDownHandler it is not supporting please any one can help
me in this regard.
regards
Lokesh

Re: Module Dependency Issue
Pavel, No, you can't exclude part of an inherited module. What you can do is refactor your modules so that you aren't inheriting bits you don't want: 1. Create a module for the bits of Module_A that don't require the maps API. Let's call it Module_A_WM (Without Maps). 2. Have Module_B inherit Module_A_WM. 3. Have Module_A inherit Module_A_WM and the maps API. Obviously you'll want a more meaningful name for the new Module_A_WM. - Isaac On Thu, Mar 12, 2009 at 11:57 AM, Pavel Byles pavelby...@gmail.com wrote: I have a module (Module_A) that inherits and requires the gwt_google_maps_api and another (Module_B) that inherits from Module_A.

Plugin based gwt web application
I'm creating a web management framework fully developed in GWT. One of the main intend of this project is to allow the end users to write there own plugins for this framework which will be displayed in one of the different panels on the framework console. One of the main requirement in this project is for the frame work to load the plugin in run time and display the gwt app created by the end user. One of the problems I'm facing over here is how will i compile a small set of gwt code with out any EntryPoint and use the generated *javascript* from the framework. I know we can compile without the Entrypoint but the main problem I'm facing is compiling code to javascript instead of java classes and loading it to the framework which will have to use these JS and display the plugin widget on the framework console on runtime.

Re: Module Dependency Issue
My regular version does import a class that extends a map, so that may be the problem. I will refactor. On Thu, Mar 12, 2009 at 12:10 PM, Isaac Truett itru...@gmail.com wrote: The compiler indeed will do an admirable job of removing dead code. But since you're seeing runtime errors in the mobile version, I'd say it's very likely that you have live references to the maps code somewhere, possibly in the parsers you mentioned. Refactoring will help you eliminate those references or isolate them so that your mobile version only gets the code it needs, making it smaller and faster (both especially important for mobile apps, as I'm sure you are already aware). It's possible that your regular version's entry point references maps code. As I understand it, both of the entry points defined in the Module_A and Module_B will be executed when Module_B loads since B inherits A's entry point. Refactoring so that A and B inherit from a common base (without an entry point) will solve that.

Interesting problem.
This is going to need some kind of infraestructure and policy. I am just
thinking out loud waiting more experienced people point problems and what
can work. To start you need two things:
a) Know what plugins exists, a registry of plugins
b) Attach them into a panel, listen events and useful stuff
To install the plugins you can drop them in folder. To know what exists you
can do it manually, setting up a file and fetching it from the client side.
To do it automatically you can do it server side and rpc-serialize'it to
client side.
To load them the main problem is obfuscated code. I imagine you can't mix up
source comming from different optimizer executions. Let's suposse we can.
Then if we know the plugin main object name, we can construct a jsni method
to forge a call to the pluing initializer function, with the panel id to be
attached.
native void initPlugin(String objectName, String panelId) /*-{
var method = @+objectName+::doInit(Ljava/lang/String;);
eval( method+('+panelId+'); );
}-*/;
That should give to the plugin the ability to put itself into the panel and
call whatever container hooks needs.
Another way is doing plugin static iniatilazation self injection:
class CoolPlugin extends Plugin {
static {
Application.staticSomething.register(new CoolPlugin());
}
So the application can take further actions...

Re: error in database connection
Hi Poonam, Apart from making sure your Hibernate and applicationContext.xml configurations are correct, I think another major cause for the stack trace you're seeing is that you're mixing server-side Java code with client-side GWT code. It's important to recall that GWT code gets converted into equivalent JavaScript, therefore you can't directly use server-side Java concepts in GWT code and expect them to work as they would in a Java runtime.

Re: error in database connection
Also just to point out, there's a number of GWT libraries for passing persistent objects across the client/server barrier. I'm not sure how well they work or of any of the dragons involved, but they do exist (hibernate4gwt was one back in the day - I believe it's been deprecated and there are more robust ones available these days).

Re: Running HTTPServlet alongside RemoteServiceServlet in Tomcat
Oh no sorry when I said the rather peculiar way, its the same peculiar way you have to do it in GWT - as in you create a 'form' with the target of your form-receiving-servlet (In my case AlbumUploadController) which has some subelements which are fileupload boxes. The implementation would be exactly the same in GWT and both were tested. Didn't even mean to mention GXT lol :P I only said 'peculiar' because its not the normal way you'd reference a servlet which responded to a GET activity like /returnPictures? img=someimg.jpg or the way you use RPCServlets. A few questions to yourself then if you wouldn't mind assisting me in a few things? When creating your war do you leave your front end bits in the www/ com.Blah.blah/ directory, or do you move them to the root of the WAR file for simpler URL's? (This isn't perhaps related to my error but i'd be interested to know if the location of the front end has a bearing on how you should call server side bits and where it should 'properly' be). In any of the HTTPServlets you run how do you handle errors? Are they thrown for Tomcat to deal with, do you catch them and do error.printStackTrace() or do you handle them some other way to get them to end up in the logs? Thanks kindly for your help :) On Mar 12, 6:48 pm, Isaac Truett itru...@gmail.com wrote: If anyone knows of any examples of a project with an RPCServlet and HTTPServlet (Any kind, a picture server, a file upload receiver, etc) running in conjunction on the server side and they both print their logs in Tomcat WAR deployment correctly that would be extraordinarily fantastic.

Now my problem is that when I use the AlbumUploader (Which being a file upload receiver is called in the rather peculiar way you have to do with file uploading in GXT) it returns absolutely fine - almost instantly. No file is uploaded, no error is returned, no logs are written and clearly that AlbumUploader either - hasn't run whatsoever - or returned null instantly without this being logged as an error. It would appear that I can't run a HTTPServlet in conjunction with an RPCServlet? Do I need to deploy these to different projects on my Tomcat server? Is there some special key in the web.xml file to make these work properly? How can I get this to write an error into one of the logs? Where does System.out.println/System.err.println print to when your running a HTTPServlet.

Re: Plugin based gwt web application
Well, one thing you can do is have the EntryPoint, and just tell plugin
developers that they have to attach to some particular div element in a
particular way, as opposed to the traditional root (i.e.
RootPanel.get(plugin-name-div)).
Then the user can request certain plugins to be added in which your GWT code
should create the div's for those plugins and load their scripts.
Hope this helps you get started. Also, I would recommend staying away from
JSNI if you're not doing something that is absolutely not supported within
the GWT framework.
Just as an extension to the Java approach below, I would prefer something
like:
public abstract class PluginEntry implements EntryPoint
{
String name;
publc PluginEntry(String pluginName)
{
name = pluginName;
}
public final void onModuleEntry()
{
}
protected abstract void onModuleEntry(
}

Re: Plugin based gwt web application
Uggh - sorry. Gmail decided to send the message for me. I've completed the
class below.
Anyways, plugins would extend PluginEntry. Again, your GWT would be
reponsible for actually injecting the plugin javascript into your page. Not
sure what the GWT-preferred way would be, but in theory (I haven't tried
this out), you might be able to do a RootPanel.get().add(new HTML(script
src='plugin/to/load'/)), although I'd test it first (I highly doubt this
would work).
A more explicit approach might be:
Document dom = Document.get();
Element head = dom.getElementsByTagName(head).getItem(0);
Element pluginScript = dom.createElement(script);
pluginScript.setPropertyString(src, plugin.js);
pluginScript.setPropertyString(type, text/javascript);
Document.appendChild(head, pluginScript);
This should work (assuming the browser supports loading scripts added
dynamically to the head element). I'd recommend testing this on several
browsers - I'm not sure which support it (although I suspect all of the
major ones).
Good luck.

Re: Plugin based gwt web application
Oh, and the RootPanel way of dynamically adding the plugin's javascript will
probably only work in onModuleLoad. The DOM approach I gave should work at
any time (i.e. as a response to user action).

Uggh - sorry. Gmail decided to send the message for me. I've completed

Anyways, plugins would extend PluginEntry. Again, your GWT would be
reponsible for actually injecting the plugin javascript into your page. Not
sure what the GWT-preferred way would be, but in theory (I haven't tried
this out), you might be able to do a RootPanel.get().add(new HTML(script
src='plugin/to/load'/)), although I'd test it first (I highly doubt this
would work).
A more explicit approach might be:
Document dom = Document.get();
Element head = dom.getElementsByTagName(head).getItem(0);
Element pluginScript = dom.createElement(script);
pluginScript.setPropertyString(src, plugin.js);
pluginScript.setPropertyString(type, text/javascript);
Document.appendChild(head, pluginScript);
This should work (assuming the browser supports loading scripts added
dynamically to the head element). I'd recommend testing this on several
browsers - I'm not sure which support it (although I suspect all of the
major ones).
Good luck.

Well, one thing you can do is have the EntryPoint, and just tell plugin
developers that they have to attach to some particular div element in a
particular way, as opposed to the traditional root (i.e.
RootPanel.get(plugin-name-div)).
Then the user can request certain plugins to be added in which your GWT
code should create the div's for those plugins and load their scripts.
Hope this helps you get started. Also, I would recommend staying away
from JSNI if you're not doing something that is absolutely not supported
within the GWT framework.
Just as an extension to the Java approach below, I would prefer something
like:
public abstract class PluginEntry implements EntryPoint
{
String name;
publc PluginEntry(String pluginName)
{
name = pluginName;
}
public final void onModuleEntry()
{
RootPanel pluginPanel = RootPanel.get(plugins-location);
pluginPanel.add(new HTML(div id=' + name + '/div));
onPluginEntry(RootPanel.get(name));
}
protected abstract void onPluginEntry(RootPanel pluginPanel);

Interesting problem.
This is going to need some kind of infraestructure and policy. I am just
thinking out loud waiting more experienced people point problems and what
can work. To start you need two things:
a) Know what plugins exists, a registry of plugins
b) Attach them into a panel, listen events and useful stuff
To install the plugins you can drop them in folder. To know what exists
you can do it manually, setting up a file and fetching it from the client
side. To do it automatically you can do it server side and rpc-serialize'it
to client side.
To load them the main problem is obfuscated code. I imagine you can't mix
up source comming from different optimizer executions. Let's suposse we can.
Then if we know the plugin main object name, we can construct a jsni method
to forge a call to the pluing initializer function, with the panel id to be
attached.
native void initPlugin(String objectName, String panelId) /*-{
var method = @+objectName+::doInit(Ljava/lang/String;);
eval( method+('+panelId+'); );
}-*/;
That should give to the plugin the ability to put itself into the panel
and call whatever container hooks needs.
Another way is doing plugin static iniatilazation self injection:
class CoolPlugin extends Plugin {
static {
Application.staticSomething.register(new CoolPlugin());
}
So the application can take further actions...

Re: Gilead 1.2.2
Right, so today I added a null check condition on the getters and setters,
that solved the problem. However, it seems like a workaround - shouldn't
beanlib check for corner cases like these? For example, build a dependency
tree between getters and copy them in the correct order. Should I forward
this report to the beanlib developers?

Hi,
First, thanks for the feedback : it is always nice to read that Gilead

About your issue, your analysis is right.
Possible workarounds would be :
- add @ServerOnly annotation on your statusName getter and setter
(Gilead will prevent it to be cloned and merged by beanlib)
- just add a null check condition in your statusName getter and
setter

Hi Bruno - first off, thanks for all of your hard work. Your project is a
real life-saver, and we're using it extensively in our project.
I'd like to report a bug. I have not tested yet with gilead 1.2.2, but
I'd
like to report it anyway.
Assume two classes:
public class Status {
Long id;
String name;
public Long getId() { ... }
public Long setId(Long id) { ... }
public String getName() { ... }
public Long setName(String name) { ... }
}
public class Ticket {
Status status;
public Status getStatus() { ... }
public Status setStatus(Status status) { ... }
public String getStatusName() { return getStatus().getName(); }
public String setStatusName(String name) { getStatus().setName(name);
}
}
I've omitted the getters and setters for brevity, as I assume their
contents
is well known. The problem occurs when serializing a Ticket instance. I
suspect that the problem lies in beanlib, though I wanted to consult you
first.
While serializing a Ticket, I receive a NullPointerException, while
beanlib
tries to access the delegate method getStatusName in Ticket. I've come to
suspect, through debugging, that this happens since beanlib tries to copy
the statusName property (which does not exist) -before- copying the
status
property. It'd be great if you could confirm my assumptions. For now,
we've
prefixed all delegate methods with an underscore, to prevent beanlib from
recognizing them as property getters/setters.
Any thoughts?

Re: Running HTTPServlet alongside RemoteServiceServlet in Tomcat
I uncovered the error as an extremely simple mistake in my servlet location naming convention which was causing nothing to be run, and no errors to be printed. Why is it that Tomcat doesn't log when an item/ servlet is requested which doesn't exist lol? GWT detects this error when your running in normal/hosted mode. Would have made this mistake so much clearer. It was the difference between /albumUpload and / AlbumUpload in the web.xml and project.gwt.xml lol. Your other comments have been massively helpful, and despite having read in tutorials and on other posts here that getting HTTPServlets to run with RPCServlets is tricky, I have to agree with yourself and say there isn't any trick to it other than having a good solid configuration in place. Thanks again :) I had spent at least 100 hours trying to track down the issues in running this and never thought to double check capitalisation.

The implementation would be exactly the same in GWT and both were tested. Didn't even mean to mention GXT lol :P I only said 'peculiar' because its not the normal way you'd reference a servlet which responded to a GET activity like /returnPictures? img=someimg.jpg or the way you use RPCServlets. Oh, well. Can't always get away with a simple blame-the-third-party-library. Just to narrow things down a bit, is the form is actually being submitted? Firebug's useful for checking that sort of thing, if you develop with Firefox. A few questions to yourself then if you wouldn't mind assisting me in a few things? Not at all. When creating your war do you leave your front end bits in the www/ com.Blah.blah/ directory, or do you move them to the root of the WAR file for simpler URL's? (This isn't perhaps related to my error but i'd be interested to know if the location of the front end has a bearing on how you should call server side bits and where it should 'properly' be). Yes, I rebase everything to the web root. It does make it easier to keep track of what each URL is relative to. In any of the HTTPServlets you run how do you handle errors? Are they thrown for Tomcat to deal with, do you catch them and do error.printStackTrace() or do you handle them some other way to get them to end up in the logs? My current approach: I catch declared exceptions and log them (java.util.logging, or your preference of logger). Not every exception is a dire emergency, of course, so a lot of benign things like a request for an invalid record ID might be logged at INFO level or lower. For routine errors like that, I'll set the HTTP status (404 seems appropriate for an ID not found scenario) and leave it at that. For something worse (gee, suddenly I can't find the database) I'll throw a new ServletException with an appropriate message (but not including the original exception, since I've already logged that).

Re: Loading Images into GWT via MySQL
The best way, IMO, is to not use GWT-RPC, but rather implement an
HttpServlet, that retrieves the data from the database and returns it with
the appropriate Content-Type in response to a GET http request. Then, you
simply place an image in your GWT code, with its source being the path to

Re: Size policies for UI controls
I think you'll want to let css do the styling for you and only hard
code styles, widths, etc in GWT when you absolutely have to.
Qt is a ui framework for creating desktop apps while GWT ultimately
has to run in the browser. So Qt has a lot more freedom in how to
layout widgets while GWT (and all web frameworks) are constrained by
how the browser operates. I think if you try to compare the two
you'll just get frustrated with all web frameworks.
Typically with the right css you can get what you want, but I've run
into a problems similar to yours and it requires a little more work in
the GWT code. If you must size Widgets to exact pixel widths/
percentages and can't achieve it with css then try creating a panel
that can size itself accordingly using .getAbsoluteLeft
(), .getOffsetWidth(), Window.getClientWidth(), etc to calculate it's
position and size. You'll need to add a WindowResizeListener also to
fire off your resize calculations anytime the user changes the size of
the window. Yeah it can be a lot of work, but most of the time there
is a css solution.
Try taking a look at this site, perhaps a 3 column page example can be
applied to your form.

I have built a number of applications with requirements for widgets
like labels, text boxes, rich edit controls, combo boxes, etc. When
designing pages in a wizard or laying out controls on a typical window

in a layout. For example, if I had a series of a widgets laid out
horizontally like this:
Label - Text box - Spacer - Label - Text box - Spaces - Label -
Text box
When these controls are placed in a container, the desirable behaviour
in this example is for the first and the last text box to expand when
the container expands. Each label should remain the same size, and the
middle text box should be a fixed size and not grow with the
container.
I do not know how to accomplish this using GWT. If I were using a
toolkit like Qt, I would set the size policy for labels to be a
fixed size and the first and last text boxes to have policies like
minimum expanding, while the middle text box would have its geometry
fixed to a certain pixel value like.
The closest I have been able to accomplishing this behaviour is
demonstrated by the following code:

Re: Performance better setting attributes in CSS or in Java code?
Hi John H,
I would also encourage you to check out a recent blog post on the GWT blog
by fellow GWT developers Chris Klundt and Eric Wuebben, who talk about their
strategy on applying CSS styles (link below). Hopefully from what was
discussed here and in the blog, you will be able to find out what approach
works best for you.
GWT: No need to shortchange your style:
http://googlewebtoolkit.blogspot.com/2008/12/gwt-no-need-to-shortchange-your-style.html
Regarding performance, whether you set properties like width and height in
GWT code or in CSS doesn't make a huge difference. What does matter is how
you go about applying the CSS styles (for example, how you use CSS selectors
to style your application). For this topic, you should get a good number of
reads by performing a web search for terms like CSS performance.
Hope that helps,

public SomePanel() {
setWidth(100px);
setWidth(100px);
}
..
}
OR
panel-style {
width: 100px;
height: 100px;
}
I tend to try setting every css style attribute during the creation of
a panel object just cause I think it's more readable and more flexible
to organize code outside of CSS style sheets. But is this a better
approach trying to achieve better performance or not or does it really
matter?

Re: Need cross-(sub)domain scripting, pretty sure xs linker's not gonna help me
Hi Jennifer, The xs linker is useful when you want to load up a GWT application in a cross-domain fashion. So, for example, if your host HTML page is living on foo.com and you wanted to load a GWT application whose JS files reside at bar.com, you could do so if the GWT application files were generated with the xs linker to emit the cross-site bootstrap script. In the case of what you're trying to do, you're right in that the xs linker probably won't be much help to you. What would help you is to make sure you've exposed the GWT methods you want to call in such a way that you can invoke them from your registerPage() function. So, for now, could you explain how you're making calls to your GWT methods from the registerPage() function? Also, how are these function calls failing in the current setup? What error messages do you get? Hope that helps, -Sumit Chandel On Tue, Mar 10, 2009 at 3:08 PM, Jennifer jgru...@gmail.com wrote: My use case is this: I have a parent frame with navigation menus implemented in GWT and a content iframe that can contain pages from different sub-domains. The pages in the content frame call a non-GWT Javascript function in the parent frame called registerPage(). The registerPage() function then calls functions that have been defined from within my GWT app in that frame. The GWT app and the parent frame HTML are both on the same server. Being able to call top.registerPage() from my content iframe should be as simple as setting document.domain in both frames, but this causes problems with GWT. I'm pretty sure that the xs linker is useless to me in this case. If not, I sure haven't been able to find anything documented that tells me how to get it to work - everything I read says to set the linker and you're set, there's no more to it. I can't even find good documentation telling me what cases it's supposed to work for. So is there anything I can do for getting cross-frame, cross-sub- domain scripting working with GWT in the mix?

Re: Plugin based gwt web application
I'm pretty sure that you need an entry point to compile a module. My
abstract method approach should do it for you.
The obfuscated code is just javascript which I explained to you how to
load.
As for the drag and drop, just search up drag drop on GWT - I'm pretty
sure there's support for it.

Hi Matías Vitali
You are right about the Pointers

We have exactly followed the same approach as you have mentioned for
installing the
plugin into a directory setting up a file with the list of plugins
installed.
But some of the issues I'm facing are
* getting to compile a plugin without any entrypoint to Javascript.
* Then the second biggest issue is getting the obfuscated code loaded
by the framework.
* Even if i manage to load it using some of the options you have
mentioned, The plugins should be able to interact
be able to interact between them selfs like drag an object from one
plugin and drop it in to another.
Are totally unaware of most of options mentioned by Vitali. I shall give it
a try. If you guys have any thing more
solid and you feel it will work, Let me know about it.
I think GWt should be coming up with some way we can load there Obfuscated
code dynamically.
Thanks a lot guys.

Uggh - sorry. Gmail decided to send the message for me. I've completed

Anyways, plugins would extend PluginEntry. Again, your GWT would be
reponsible for actually injecting the plugin javascript into your page. Not
sure what the GWT-preferred way would be, but in theory (I haven't tried
this out), you might be able to do a RootPanel.get().add(new HTML(script
src='plugin/to/load'/)), although I'd test it first (I highly doubt this
would work).
A more explicit approach might be:
Document dom = Document.get();
Element head = dom.getElementsByTagName(head).getItem(0);
Element pluginScript = dom.createElement(script);
pluginScript.setPropertyString(src, plugin.js);
pluginScript.setPropertyString(type, text/javascript);
Document.appendChild(head, pluginScript);
This should work (assuming the browser supports loading scripts added
dynamically to the head element). I'd recommend testing this on several
browsers - I'm not sure which support it (although I suspect all of the
major ones).
Good luck.

Well, one thing you can do is have the EntryPoint, and just tell plugin
developers that they have to attach to some particular div element in a
particular way, as opposed to the traditional root (i.e.
RootPanel.get(plugin-name-div)).
Then the user can request certain plugins to be added in which your GWT
code should create the div's for those plugins and load their scripts.
Hope this helps you get started. Also, I would recommend staying away
from JSNI if you're not doing something that is absolutely not supported
within the GWT framework.
Just as an extension to the Java approach below, I would prefer
something like:
public abstract class PluginEntry implements EntryPoint
{
String name;
publc PluginEntry(String pluginName)
{
name = pluginName;
}
public final void onModuleEntry()
{
RootPanel pluginPanel = RootPanel.get(plugins-location);
pluginPanel.add(new HTML(div id=' + name + '/div));
onPluginEntry(RootPanel.get(name));
}
protected abstract void onPluginEntry(RootPanel pluginPanel);
}

Interesting problem.
This is going to need some kind of infraestructure and policy. I am

I can almost certainly use some extra git commands to determine precisely whether or not there are local mods. The sweet thing about git (unlike svn) is you'll never get more than one svn revision.. it's just not possible. So the only possibilities are releases/1...@ or releases/1...@m. --Scott --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

Freeland, I decided to stage this in two sequential patches (and commits) to make it easier to review and see the log. Here's patch #1, which merely refactors the existing code to make it testable, and also makes the change in how the branch specifier is computed. The next patch, to actually add git support, should be small relative to this. Thanks!

[gwt-contrib] Re: Relaxing constraints on GWT.create()
BTW,
My proposed implementation is to rewrite these methods changing the
literal parameter to the result of invoking GWT.create() at the call
site, e.g.
interface MyService extends RemoteServiceMyServiceAsync { ... }
// example call
OAuth.withSignature(MyService.class).method1(arg1, arg2, asyncCallback);
public class OAuth {
@GwtCreate // method must be static, class parameter must be final
public static S, T extends RemoteServiceS S withSignature(final
ClassT service) {
// GWT.create with non-literal ONLY allowed
// if enclosing method is @GwtCreate and
// variable statically resolvable to literal param
S async = GWT.create(service);
((ServiceDefTarget)async).setRequestBuilderCallback(new
OAuthRequestBuilderSigner());
return async;
}
}
after rewrite at callsite:
Object async = GWT.create(MyService.class);
OAuth.withSignature(async).method1(arg1, arg2, asyncCallback);
rewritten method:
public class OAuth {
@GwtCreate // method must be static, class parameter must be final
public static S, T extends RemoteServiceS S withSignature(Object
asyncInstance) {
//S async = GWT.create(service); replaced with instance
S async = (S)asyncInstance;
((ServiceDefTarget)async).setRequestBuilderCallback(new
OAuthRequestBuilderSigner());
return async;
}
}
This doesn't handle generator override or extra params, but it's a
start and could work with minimal changes to ReplaceRebinds.

[gwt-contrib] Re: Relaxing constraints on GWT.create()
+1 for this implementation.
This is a lot clearer than a class - implementation lookup map or
inlining the whole method at each call site. As long as the bytecode
is rewritten in hosted mode to match the expected order of operations,
there shouldn't be any surprises at compile time.
Could this cause issues with anyone running GWT.create() in server-
side code? Does that even work today?
