How to tell if an image is done loading (or failed) for sure, given LoadListener is broken on IE?
Hi, Is there a cross-browser compatible, sure-fire way to tell if an image is loaded? I have used Loadlistener observers, but they do not work consistently on IE, and that's a deal breaker... I need it for delaying preloading of hidden images until the visible ones have loaded, or have failed loading. Regards, Anders S.

Re: GWT 1.6 with Maven and build system questions/survey...
Who agrees that having a solid, feature complete Maven plugin from Google would increase adoption of GWT faster than anything? I think the google team is focusing in the basics first, and that implies not being able to deliver all the goodies at the same time, I think it all fits rather nicely with the agile mantra: deliver early, deliver often. If they tried delivering the Eclipse plugin (and all other popular IDEs' plugins for that matter) and the maven plugin at the same time they deliver the actual product (GWT) they couldn't possibly deliver that often. Not to mention that they don't seem to be maven people, they're rather ant users, so why not leave it to the community, in true open source spirit, to build the tools they need, they even help out when there's something that doesn't work nicely with our tools (one of the issues resolved in 1.6 was specifically adressed to allow a nicer maven integration), I don't think we can possibly ask for more cooperation from them. Maybe file an enhancement request? I totally agree with Jeff, if you think a great maven plugin would help with adoption, why not try the one from the mojo project (which is quite nice by the way) and report any issues that you find with it. I don't think we can have a more official plugin than that (after all, they're the maven experts, not google ) Cheers, Salvador --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Uncaught exception escaped: JavaScriptException: (Error): Invalid argument.
Hi All,
I am just trying out the example code given in the book named
Google Web Toolkit Solutions-More cool and useful stuff for
resizable columns in FlexGrid.
I have created (carefully!!) all the required classes as like
mentioned in the book.
When I run the application, its launching without any problem. The
moment, when I try to resize any column, I am getting the following
exception displayed in the Shell window
[ERROR] Uncaught exception escaped

I have checked the method setColumnWidth, it was like below.
public void setColumnWidth(int column, int width) {
getColumnFormatter().setWidth(column,width + px);
}
And I knew that setWidth method args are int and String. so on the
safer side I had changed the args like below.
public void setColumnWidth(int column, int width) {
getColumnFormatter().setWidth(column,Integer.toString(width) + px);
}
But still I am getting the same exception. Any one experienced such
issue?
Or please advise what is wrong in this case
Thanks in advance

Re: How to share RPC service between GWT applications?
Thanks for the reply. The RPC servlet uses a db layer jar which configures a Hibernate factory. Because of different classloaders I assume that there will be 2 instances of this factory. But I cannot say if this will present an issue until I test it. On Apr 14, 9:23 pm, gregor greg.power...@googlemail.com wrote: You can do this if you place your RPC services in a separate module that is inherited by the two main application modules. In this situation you can specify the RPC servlets in the common module gwt.xml file and this will work for hosted mode, but I think you have to map them separately (i.e. in duplicate) in each main module's web.xml for deployment - AFAIK there is no way around that (app server/ servlet specification issue, not GWT). At run time you will end up with two instances of each servlet loaded by the two main module's classloaders (again app server/servlet specification issue, not GWT) which may or may not present you with an issue depending on what you are doing.

Re: How to tell if an image is done loading (or failed) for sure, given LoadListener is broken on IE?
I don't think LoadListener is broken, it's just that there's a catch in using it. The actual loading of the image doesn't take place if such image is not attached to the document, so if you really want to load it without the user seeing the actual load, you have to use a trick like loading it in a hidden part of the document: //get the size of the window int width = Window.getClientWidth(); int height = Window.getClientHeight(); //instantiate image and add loadListeners: Image img = new Image(example.jpg); img.addLoadListener(yourloadListener); //attach image to the rootPanel in a place not visible to the user, this is where the actual loading takes place RootPanel.get.add(img, width, height); //use onLoad to put the image in the right place This has the effect of showing scrollbars (which you can hide) but the code gets more complicated and it's beyond what I wantedto show you Cheers, Salvador On Apr 15, 9:01 am, dduck anders.johansen.a...@gmail.com wrote: Hi, Is there a cross-browser compatible, sure-fire way to tell if an image is loaded?

Catching exception in a filter.
I have maven GWT 1.5 project split into few parts. One of them is WAR
with client side and other is WAR with server side included in some
EAR application. There is also some JAR wich is proxy between client
and server, i mean client and server do not see each other, but they
are dependent of this JAR so all common classes and f.e. RPC
interfaces are defined there.
I defined SecurityException in this JAR:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package pl.fizzycomp.client.common;
import com.google.gwt.user.client.rpc.IsSerializable;
import java.util.ArrayList;
import java.util.List;
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package pl.fizzycomp.client.common;
import com.google.gwt.user.client.rpc.IsSerializable;
import java.util.ArrayList;
import java.util.List;
public class SecurityException extends Exception implements
IsSerializable {
//CONSTRUCTORS HERE
/**
* User name of user that didn't have persmission
*/
private String userName;
/**
* Set of examined and not found roles
*/
private ListString rolesExamined = new ArrayListString();
/**
* Adds role to @see rolesExamined
* @param roleName role to add
*/
public void addRole(String roleName){
rolesExamined.add(roleName);
}
/**
* Adds roles to @see rolesExamined
* @param roleName list of roles to add
*/
public void addRoles(ListString roleNames){
rolesExamined.addAll(roleNames);
}
/**
* @return @see rolesExamined as a String
*/
public String getRolesExamined() {
return rolesExamined.toString();
}
/**
* @return @see userName
*/
public String getUserName() {
return userName;
}
/**
* Sets @see userName to given value
* @param userName value
*/
public void setUserName(String userName) {
this.userName = userName;
}
/**
* Returns message of the exception and values of @see userName
and @see rolesExamined
* @return
*/
public String toString() {
return super.toString() + ; user: + userName + , examined
roles: + rolesExamined.toString();
}
}
All RPC methods that throws SecurityException and their synchronous
interfaces declare this fact in the throws phrase.
This exception I wanna catch and service (by writing info to the log
and database table) in an aspect manner on the server side before it
reaches client side and is silenced by the one trying to break
security policy.
So I declared in web.xml on the server WAR:
!-- This filter handles the
pl.fizzycomp.client.common.SecurityException --
filter
filter-nameSecurityExceptionFilter/filter-name
filter-classpl.xxx.server.filter.SecurityExceptionFilter/
filter-class
/filter
filter-mapping
filter-nameSecurityExceptionFilter/filter-name
url-pattern/services/*/url-pattern
/filter-mapping
And the code of the filter:
public class SecurityExceptionFilter implements Filter {
private FilterConfig filterConfig = null;
private static Logger log = Logger.getLogger
(SecurityExceptionFilter.class);
@EJB
private ErrorCodesFacadeLocal errorCodesFacade;
@Override
public void init(FilterConfig config) throws ServletException {
this.filterConfig = config;
}
@Override
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {
if (filterConfig == null){
return;
}
try {
System.out.println(+++
SecurityExceptionFilter);
System.out.println(request.toString());
System.out.println
(---);
System.out.println(response.toString());
System.out.println(++
+);
chain.doFilter(request, response);
}
catch (Throwable t){
log.fatal(Security violation attempt occured. Event will
be written to ERROR_CODES table., t);
//TODO - database stuff
}
}
/*
private SecurityException examineSecurityException(final Throwable
t){
Throwable temp = t;
while (temp != null){
if (temp instanceof SecurityException){
return (SecurityException) temp;
}
temp = temp.getCause();
}
return null;
}
*/
@Override
public void destroy() {
this.filterConfig = null;
}
}
Then I declared RPC method:
public ListIPersonWindowMember doAdvancedPersonSearch
(IAdvancedPersonSearchParameter apsp) throws SecurityException
{
if (true){
SecurityException e = new SecurityException
(testsecurityex);
e.setUserName(username);
e.addRole(role1);e.addRole(role2);

Your code snippet isn't enough on its own to understand what's going on - you
also need the
definition of stocks. Perhaps this is your problem. It's defined like this:
private ArrayListString stocks = new ArrayListString();
Does that help you to see what's happening?

Re: Need help understanding code snippet
Yellow Jersey schrieb:

List.indexOf(Object) looks for the position of a given object.
So without checking the actual source the implementiation in
e.g. ArrayList should be something like this:
public int indexOf(Object o){
for (int i = 0; i elems.length; i++){
if (elems[i] == o){
return i;
}
}
return -1;
}
So the onClick-method looks for the position of the currently
added symbol (I assume that this part of code is embedded
in a loop that fills the stocksFlexTable) inside an internal
list, removes it from there:
stocks.remove(removedIndex);
and continues by removing the symbol from a FlexTable that
contains a header-row in addition to the data-rows:
stocksFlexTable.removeRow(removedIndex+1);
The internal list must contain the symbol, otherwise the whole
thing crashes because of list.remove(-1).
If you need more help about this you should change to a group
that covers that topic, e.g. in the comp.lang.java-hierarchy,
because this has nothing to do with GWT but with the Java-API.

CSS stylename code generation
Hello
I am trying android now, and i appreciate the simple code generation
of the class 'R'.
For non android user, it allows to associate a graphic element to an
id. The id given in an xml file is automatically generated in java, in
the class R.
I am thinking about an equivalent code generation for the css files in
GWT.
example :
myStyle.css
.style{
...
}
.style-dependentStyle{
...
}
#element {
...
}
would give something like
/* AUTO-GENERATED FILE. DO NOT MODIFY.*/
public final class Styles {
public static final class MyStyle {
public static final String style = style;
public static final String style_dependentStyle =
dependentStyle;
public static final String IDelement = element;
}
}
which could be used like this:
widget.addStyleName(Styles.MyStyle.style);
widget.addStyleDependentName(Styles.MyStyle.style_dependantStyle);
widget.getElement.setId(Styles.MyStyle.IDelement);
The main advantage is to respect the DRY principle by avoiding boring
manual constants declaration.
This feature could be a part of the new GWT eclipse plugin
http://code.google.com/eclipse/, or a standalone eclipse plugin.
What do you think about it ?
Does anyone is interested in ?

Re: Uncaught exception escaped: JavaScriptException: (Error): Invalid argument.
I've experienced a similar issue on IE (Firefox was fine) when trying
to run a custom animation. More specifically, I got the same
InvalidArgument javascript error. I haven't tried to pin down the
exact specific problem as I don't have an IE javascript debugger but
I'm pretty sure the cause is the buggy javascript interpreter from IE.
If you want to look at a resizable columns example in FlexGrid, try
looking at the one from the incubator, we use it in our projects and
it works pretty well.
http://code.google.com/p/google-web-toolkit-incubator/source/browse/#svn/trunk/src/com/google/gwt/widgetideas/table/client
You should note that the stack trace from your exception points at one
of your classes and you might be able to see what's wrong if you debug
your application and put a breakpoint at that location :
(com.ibsplc.client.ui.table.EasyFlexTableResizable.setColumnWidth
(EasyFlexTableResizable.java:43) ) - That tells you where the
exception is thrown

Re: Deferred Bind on Login to load different user interface
The Showcase is a pretty neat example of how do you go about handling skins: * Go to http://gwt.google.com/samples/Showcase/Showcase.html * Click in one if the colored rectangles located in the top right corner of the page * Voilà !

I'm thinking in terms of using deferred binding for skin/layout differences it shouldn't be such a bad idea if it's small alterations such as colours/layout. Considering that internationalisation/browser layout differences work along the same lines in terms of the scope of changes. The workflow i've had it laid out in though in my head is like this: 1. default entry point with default permutation is loaded with login form 2. user logs in with user / pass / layout 3. system checks for valid login 4. if successful login redirect back to default entry point with when-property-is name=skin value=GREEN_LAYOUT/ My issue is on the redirect how would i go about setting the property value that i wish to load? Would this be appended to the URL ala locales in internationalisation? This then brings up another issue. If it does involve appending to the URL what if i only wish to make the skin available to only a particular set of users. Else i'm thinking at this point maybe dynamically downloading and loading skin X after login may be a better choice as opposed to deffered binding.

Re: CSS stylename code generation
It seems to look like what i dreamt.
It is not code generation, but a java view of the CSS ressource
(retrieved as an image Bundle)
http://code.google.com/p/google-web-toolkit-incubator/wiki/CssResourceCookbook
CssResource will use method names as CSS class names to obfuscate at
runtime.
interface MyCss extends CssResource {
String className();
}
interface MyResources extends ImmutableResourceBundle {
@Resource(my.css)
MyCss css();
}
All instances of a selector with .className will be replaced with an
obfuscated symbol when the CSS is compiled. To use the obfuscated
name:
MyResources resources = GWT.create(MyResources.class);
Label l = new Label(Some text);
l.addStyleName(resources.css().className());
If you have class names in your css file that are not legal Java
identifiers, you can use the @ClassName annotation on the accessor
method:
interface MyCss extends CssResource {
@ClassName(some-other-name)
String someOtherName();
}
It allows to link java to css. but it is still a rewrite.
If it alert you about an error at compile time (as the imageBundle
do), it is still an enhancement.
I take it!
Thank you Vador ;)

Just use a different war directory (and use the -war option of the HostedMode/Compiler to tell it which one to use) with a different web.xml. Or you could, for example, have a web.xml.deploy file and use Ant to replace the web.xml (used for HostedMode) content with the one from the web.xml.deploy file when packaging your app. If you're not using Jetty on your deployment server, you could probably configure your proxy in a WEB-INF/jetty-web.xml (I'm not used to Jetty and haven't found how to do it yet; looks like it would have to be a proxy *handler*, not servlet).

Re: GWT Serialization with CustomFieldSerializer fails because of SerializationPolicy
perhaps can we use annotations like @gwt.typeArgs Those are deprecated, you should really avoid using them a simple java class containing a MapString,Object Can't you just use a MapString, Serializable ? If the map is going to be travelling through RPCs you really shouldn't be putting objects that don't implement Serializable into it. Cheers, Salvador For every service gwt has a list of classes which can be Serialized (whitelist). If my understanding is right this list is generated by the compiler at compile time by analizing the members of a class. But we can have classes (which ARE serializable) inside our transient map, but gwt will not serialize this classes because of the SerializationPolicy (these classes could not be found by the compiler at compile time). Is there any way to extend the white list of SerializationPolicy.java ? If I add all classes as private members to my class the members are found and the class can be serialized, but this is anoying and we cant do this for all classes (we dynamically decide which classes we need to transfer) Anyone got any expierence with that?

Re: How to share RPC service between GWT applications?
I would be careful about multiple Hibernate session factories etc. You may be able to get away with it, but there are potential problems that might be difficult to trace. I would do some research into your options as they relate to your particular use case. Two main ways to deal with this are: 1. configure data source as JNDI lookup. That works with servlet container only, e.g. Tomcat, Jetty. I'm pretty sure Spring provides ways to do this in conjunction with Hibernate for example. 2. deploy as an EAR that houses both web apps (as WARs) and a common data access/transaction management tier (as a JAR). You might delegate the server side work and data access from your RPC servlets to a session EJB for example. You will need to use a full blown Java EE app server like JBoss for this of course, and run GWT hosted mode with - noserver option etc. On Apr 15, 8:38 am, jfeid jannis.feida...@gmail.com wrote: Thanks for the reply. The RPC servlet uses a db layer jar which configures a Hibernate factory. Because of different classloaders I assume that there will be 2 instances of this factory.

On Apr 14, 9:23 pm, gregor greg.power...@googlemail.com wrote: You can do this if you place your RPC services in a separate module that is inherited by the two main application modules. In this situation you can specify the RPC servlets in the common module gwt.xml file and this will work for hosted mode, but I think you have to map them separately (i.e. in duplicate) in each main module's web.xml for deployment - AFAIK there is no way around that (app server/ servlet specification issue, not GWT). At run time you will end up with two instances of each servlet loaded by the two main module's classloaders (again app server/servlet specification issue, not GWT) which may or may not present you with an issue depending on what you are doing.

Re: File Upload with rpc call
Yes, you can do it only in FireFox 3, as far as I know.
If you have FileUpload element then you can acces to file's data from
native JavaScript.
For example you have FileUpload and set its ID to file then
following method returns binary data contained in file:
private native String getFileBinary() /*-{
return $doc.getElementById(file).files[0].getAsBinary();
}-*/;
Then you are free to use returned data in RPC call or whatever you
want.
You can read more here: https://developer.mozilla.org/En/NsIDOMFile

Hi
I'am working with the DateBox component: show a calendar when you

/*dateBox.setFormat(new DateBox.DefaultFormat

This code in DatePicker works. Anybody knows why? Maybe it is a bug of
this componente?
Seems related to issues 1634 and 3553:
http://code.google.com/p/google-web-toolkit/issues/detail?id=1634
http://code.google.com/p/google-web-toolkit/issues/detail?id=3553
namely, when you click on the popup calendar, the textbox looses focus
and fires a value change event (then only the click on the popup
calendar has a chance to select a date, thus set the datebox's value
and fire the expected value change event).
(I don't understand you try/catch check with format(): getValue will
only return a non-null value if the textbox value is a date in the
appropriate format; could it be your actual problem? dateBox.getValue
() being null?)

I have checked the method setColumnWidth, it was like below.
public void setColumnWidth(int column, int width) {
getColumnFormatter().setWidth(column,width + px);
}
And I knew that setWidth method args are int and String. so on the
safer side I had changed the args like below.
public void setColumnWidth(int column, int width) {
getColumnFormatter().setWidth(column,Integer.toString(width) + px);
}
But still I am getting the same exception. Any one experienced such
issue?
Or please advise what is wrong in this case
Thanks in advance

How to get URL for image within an image bundle - if possible
Hi, I'm trying to use SmartGWT which doesn't seem to support GWT Image Bundles. I would like to set a background image on a canvas to be an image from an image bundle.

Re: GWT 1.6, JSP's wont compile.
The app server is the one bundled with GWT hosted mode, I believe it's Jetty. If you use a servlet that has 1.5 stuff in it, it works fine. When I was investigating, I noticed that the JSP does successfully produce a servlet. I copied this servlet and compiled it myself and it worked fine, even in hosted mode. I believe it's failing at the point where the generated servlet (.java) is being compiled into a class (.class).

Re: How to get URL for image within an image bundle - if possible
The imageBundle has a unique URL for all the images, in fact it's a one big image made by all the little ones. GWT loads the whole image but uses a clipper control to show only the clip containing the image.

Re: GWT 1.6, JSP's wont compile.
It looks like it is a bug with Jetty instance used when a GWT-only web app has JSPs with generics. It does not appear that the App Engine devserverhttp://code.google.com/appengine/docs/java/tools/devserver.html has this problem. I went ahead and filed a bug against GWT for this, Issue 3557http://code.google.com/p/google-web-toolkit/issues/detail?id=3557. As a workaround, you could add App Engine to your project.

Re: does com.google.gwt.dev.Compiler need to run prior to hosted mode?
Perhaps I'm not understanding the previous discussion completely and I do not use NetBeans, but I do use GWT's hosted mode with the -noserver option and enjoy the benefits of hosted mode's rapid develop/test cycle. All it takes for me to see a change in the client code is hitting the hosted mode browser's reload button. We use our own ant-based build system. To use hosted mode, we: 1.) Do one compilation of the client code (GWTCompiler) 2.) Compile the server code. 3.) Launch our web server (Jetty, in our case) 4.) Launch hosted mode After this, hitting reload in hosted mode reflects changes in the client's source files (we never need to re-run GWTCompiler). Of course, for changes to the server code, jetty needs to reload the war (although not for css changes, which also saves time).

So if it was correctly built before, such a change could not have introduced new API calls outside of the subset that GWT supports. It looks to me like that delete method is a problem with low-level class reloading that may be broken on the current JDK that comes with MacOS X. I've never seen that before, though.

Re: Load gwt module before image are loaded on IE7
Ok, i must have understand something wrong then, but from the wiki i read the last four sequences as following 9. ...cache.js completes. onModuleLoad() is not called yet, as we're still waiting on externalScriptOne.js to complete before the document is considered 'ready'. 10. externalScriptOne.js completes. The document is ready, so onModuleLoad() fires. 11. reallyBigImageTwo.jpg completes. 12. body.onload() fires, in this case showing an alert() box. So as described in the wiki the onModuleLoad will fire once the last js script is loaded, but before the reallyBigImageTwo is loaded. This applies to all normal browsers it seems except IE...

Re: No JSNI method generated

The reason i'm not using existing GWT widgets, which my example doesn't show, is because i'm trying to attach an onclick() event to ordered list items (litext/li). There doesn't seem to be a widget which easily allows for this. Someone else in this group had suggested they do what i was trying to do. I'm trying to port an existing interface which i did in jquery() to GWT... one of the key components uses plain list items which i attach listeners to. While the JSNI path is (more than) OK when prototyping your port, I'd recommend you create a widget that suits your needs instead. You could also (now, or as part of the widget) take advantage of event bubbling: register a ClickHandler at the container level, look at the ClickEvent.getNativeEvent().getEventTarget() (it should be an Element, check with Element.is(...) and cast with Element.as(...)) and walk up the tree (getParent) until you find a LI (elem.getTagName ().equalsIgnoreCase(LIElement.TAG)) or your widget's element (getElement()). FYI, that's what the grids (Grid and FlexTable) in GWT do for the cell click events. What you explain makes sense and your option #2 for using the jsni name of the java function seems the easiest. I doubt it'll work (I'm almost sure it won't; JSNI reference resolving is done by parsing the JavaScript code, not using regexes and find/ replace). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Smartgwt ListGrid Tick boxes
Hi, I've written an application in gwt which makes use of smartGWT in particular ListGrids with check boxes. Under linux I have no problems. However using a Mac or Windows smartgwt does not appear to have the SelectionAppearance.CHECKBOX option and gives me an error in Eclipse. (someResultsGrid.setSelectionAppearance (SelectionAppearance.CHECKBOX);) Is this a bug? I'm using the smartgwt-1.0b2-SNAPSHOT.jar.

Re: Load gwt module before image are loaded on IE7
Try putting your script for nocache.js in your body instead of head On Wed, Apr 15, 2009 at 11:59 AM, Dominik Steiner dominik.j.stei...@googlemail.com wrote: Ok, i must have understand something wrong then, but from the wiki i read the last four sequences as following 9. ...cache.js completes. onModuleLoad() is not called yet, as we're still waiting on externalScriptOne.js to complete before the document is considered 'ready'. 10. externalScriptOne.js completes. The document is ready, so onModuleLoad() fires. 11. reallyBigImageTwo.jpg completes. 12. body.onload() fires, in this case showing an alert() box. So as described in the wiki the onModuleLoad will fire once the last js script is loaded, but before the reallyBigImageTwo is loaded. This applies to all normal browsers it seems except IE...

Re: File Upload with rpc call
http://igstan.blogspot.com/2009/01/pure-javascript-file-upload.html
From the comments you cannot read more than 100MB (although I doubt this is
an actual restriction) you have to read the whole file (meaning large
files will pause your program for quite a while).
More importantly, this is FF3 only, which leaves out users of any other
browser which is even worse than the flash option.

For example you have FileUpload and set its ID to file then

}-*/;
Then you are free to use returned data in RPC call or whatever you

Sorry - meant to make it clear, particularly since this is FF specific (if
Chrome had this API, it would only apply to the tab), this will hang your
browser until the entire file is read into memory. Only background threads
would solve this issue, but that would further lower your user base to FF
3.5 Google Gears users (assuming you created an API wrapper that supported
both).

GWT eclipse plug manual install?
All, I have looked and I cannot find a link from where I can download GWT 1.6 for a manual install. (I could also be blind.) Is there such a thing, or is it update site or nothing? I am trying to upgrade to GWT 1.6. When I attempt to do so using the update site, It throws an error (see below). Has anyone seen this kind of thing before? I have successfully upgraded two other machines. It's only this third box that gives me trouble. All three machines have eclipse 3.4 on WinXP.

Re: efficiency of my gwt application
- the rpc is quite slow. i am using it to return a few thousand by eleven column of data(String) a) RPC is *much* slower in hosted mode than deployed in web mode. You should time your RPC performance (separately to the table draw time) when deployed to find out how it is really performing b) having said that, fetching several thousand rows of data and displaying it in one operation is likely to be unacceptably slow. It takes javascript engines quite a long time attach thousands of HTML elements to the DOM. It is generally much faster to do it in page- fulls even though it takes multiple RPC calls to do it that way. You might want to check out the PagingScrollTable in the incubator. - i have a tabset within my application which i copied from the smartgwt showcase when i click on new tab with google map on it.. it will normally hang and need a few minutes to finally display the result. sometimes, it will hang forever. SmartGWT is a GWT wrapper around a javascript library. It might be difficult to figure out why it is not performing well for your use case, and very difficult to do anything about it if you can. Generally speaking, if you use pure GWT you will get higher performance and more flexibility and code transparency. can you give me some links to these tutorials? if you have any. thanks again..

JAXB generated classes under GWT
I also tried to use JAXB generated classes in GWT. When i add the JAXB Sources to the GWT Compiler it works with a lot of errors. But when i tried to use some imports( import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement;) the compiler fails. Has anyone a solution to use JAXB generated classes in GWT? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Environment variables for servlet in hosted mode
I just upgraded to GWT 1.6 and have the following problem. The servlet
of my web app calls a native application on the server. In order to
test this on my local machine I had used environment variables to
specify where the binary resides.
With GWT 1.5 I could set them in my Eclipse launch config for
debugging in hosted mode on my local machine and as init parameters in
the web.xml file for the deployed version running on the web server.
So my RemoteServiceServlet contains this init method:
public void init(ServletConfig config) throws ServletException{
super.init(config);
myapp_cmd = config.getInitParameter(MYAPP_CMD);
myapp_param = config.getInitParameter(MYAPP_PARAM);
output_dir = config.getInitParameter(OUTPUT_DIR);
if (myapp_cmd == null) {
myapp_cmd = System.getenv(MYAPP_CMD);
}
if (myapp_param == null) {
myapp_param = System.getenv(MYAPP_PARAM);
}
if (output_dir == null) {
output_dir = System.getenv(OUTPUT_DIR);
}
}
GWT 1.6 seems to load the web.xml file even when running in hosted
mode, thereby breaking my code. I searched the help for information on
the issue, but couldn't find anything. Could someone tell me how I
should include these parameters/environment variables instead?

Re: How to include javascript files in GWT with eclipse plugin?
Well, what I was concerned with was, in Hosted mode, Eclipse making sure to copy local JS resources into the desired place in the target folder in the 'war' hierarchy. I found the answer to my problem, however: 1. Put my 'js' folder in myProject/war/WEB-INF/classes/com/mycompany/ myproject/web/public 2. The references in the .gwt.xml file used relative paths 'js/...' The GWT builder in Eclipse then copied everything in 'js' to myproject/ war/mymodule/js I don't know why it works this way, but it does. - Tim On Apr 15, 3:15 am, Salvador Diaz diaz.salva...@gmail.com wrote: If all you want to do is include some external js files:http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=goog...

Re: Problem in downloading Google Plugin for Eclipse
Hi Sandeep, The URLs are working, although it may not appear so if you navigate directly to them in a web browser. These URLs are Eclipse update sites, which means you'll need to use Eclipse's update mechanism to install the plugin. See the documentation for Eclipse 3.3 (http:// code.google.com/eclipse/docs/install-eclipse-3.3.html) or Eclipse 3.4 (http://code.google.com/eclipse/docs/install-eclipse-3.4.html). From a web browser, these URLs will indeed produce a 404, even when the update site is ok. To test them from a browser, just tack on / site.xml to the end of the URL, and you should see a short message indicating that you're hitting the Google plugin update site.

Problem matching an empty cell in a Grid
Hi all I hope that you can help me with a small issue I am having. Basically I am trying to get my program to return true when a cell in a grid is empty. I have found that if I print the contents of the 'empty' grid to console it is a single space character but if I try to match it to that it returns false! Here is a copy of my code: String s = t.getText(1, 1); //the empty cel in the grid String r = ; //a string with just a single space boolean b = t.getText(1, 1).equals(r); System.out.println(Empty: + b); This outputs: Empty: false in the console I have tried matching a cell that has data in it and this returns true which is confusing me! Here is that copy: boolean b2 = t.getText(3, 1).equals(event1); System.out.println(Event1: + b2); This outputs: Event1: true in console Any help will be greatly appreciated! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT Serialization with CustomFieldSerializer fails because of SerializationPolicy
The problem is that the compiler will create the code for al objects in the classpath that implement serialiazable (which are more ore less 1+). This results in enormous compile time and huge javascript... absolutely not doable any more suggestions? 2009/4/15 Salvador Diaz diaz.salva...@gmail.com perhaps can we use annotations like @gwt.typeArgs Those are deprecated, you should really avoid using them a simple java class containing a MapString,Object Can't you just use a MapString, Serializable ? If the map is going to be travelling through RPCs you really shouldn't be putting objects that don't implement Serializable into it. Cheers, Salvador For every service gwt has a list of classes which can be Serialized (whitelist). If my understanding is right this list is generated by the compiler at compile time by analizing the members of a class. But we can have classes (which ARE serializable) inside our transient map, but gwt will not serialize this classes because of the SerializationPolicy (these classes could not be found by the compiler at compile time). Is there any way to extend the white list of SerializationPolicy.java ? If I add all classes as private members to my class the members are found and the class can be serialized, but this is anoying and we cant do this for all classes (we dynamically decide which classes we need to transfer) Anyone got any expierence with that?

Re: GWT 1.6 with Maven and build system questions/survey...
On second though I think I agree with Salvador. Looking closer at the Codehaus plugin it should do the job job in the long term. On Apr 15, 1:20 am, Salvador Diaz diaz.salva...@gmail.com wrote: Who agrees that having a solid, feature complete Maven plugin from Google would increase adoption of GWT faster than anything? I think the google team is focusing in the basics first, and that implies not being able to deliver all the goodies at the same time, I think it all fits rather nicely with the agile mantra: deliver early, deliver often. If they tried delivering the Eclipse plugin (and all other popular IDEs' plugins for that matter) and the maven plugin at the same time they deliver the actual product (GWT) they couldn't possibly deliver that often. Not to mention that they don't seem to be maven people, they're rather ant users, so why not leave it to the community, in true open source spirit, to build the tools they need, they even help out when there's something that doesn't work nicely with our tools (one of the issues resolved in 1.6 was specifically adressed to allow a nicer maven integration), I don't think we can possibly ask for more cooperation from them. Maybe file an enhancement request? I totally agree with Jeff, if you think a great maven plugin would help with adoption, why not try the one from the mojo project (which is quite nice by the way) and report any issues that you find with it. I don't think we can have a more official plugin than that (after all, they're the maven experts, not google ) Cheers, Salvador --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Trouble with asynchronous calls
Hello:
Just started using GWT and I am having difficult tailoring my code to
the asynchronous nature of RPC calls. Specifically, my code asks for
the results of an RPC call before anything is returned.
Here is my class which calls a service. Instead of using an inner
class for the AsyncCallback, I use a separate implementation,
FormAsyncCallback, whose code is also below:
package com.gallup.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
public class FormService {
public String call(FormBean formBean) throws FormException{
FormRemoteServiceAsync serviceProxy = (FormRemoteServiceAsync)
GWT.create(FormRemoteService.class);
ServiceDefTarget target = (ServiceDefTarget) serviceProxy;
String serviceURL = GWT.getModuleBaseURL() + formservice;
if (GWT.isScript()) {
serviceURL = /Struts2GWT/formservice;
}
target.setServiceEntryPoint(serviceURL);
final String successMessage = null;
FormAsyncCallback callback = new FormAsyncCallback();
serviceProxy.setForm(formBean, callback);
if (!callback.isHadError()) {
GWT.log(A, null);
return callback.getSuccessMessage();
}
else {
throw new FormException(callback.getErrorMessage());
}
}
}
package com.gallup.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
public class FormAsyncCallback implements AsyncCallback {
private String successMessage = null;
private boolean hadError = false;
private String errorMessage = null;
public void onFailure(Throwable t) {
hadError = true;
GWT.log(, null);
errorMessage = t.getMessage();
}
public void onSuccess(Object result) {
GWT.log(C, null);
successMessage = (String) result;
}
public String getSuccessMessage() {
return successMessage;
}
public boolean isHadError() {
return hadError;
}
public String getErrorMessage() {
return errorMessage;
}
public boolean isReturned() {
return returned;
}
}
My problem is that AAA always prints before B or
CCC. I really want my code to wait for the RPC call to return
before I interrogate the results. Does anybody have suggestions?
Thanks
Eric

Re: Is it possible to extend a Popup or DialogBox to detect when its moved?
I'm not sure precisely how to override in this case though.
I see the onMouseUp event in the class, and I try putting this into my
widget (which extends DialogBox).
@Override
public void onMouseUp(Widget sender, int x, int y) {
dragging = false;
DOM.releaseCapture(getElement());
}
(basicaly an exact copy of whats in the class's over mouseup event).
However;
a) dragging is not visible error
b) It says onMouseUp is depreciated anyway and to use endDragging.
(Looking at enddragging;
protected void endDragging(MouseUpEvent event) {
onMouseUp(caption, event.getX(), event.getY());
}
)

Re: efficiency of my gwt application
On Apr 15, 2009, at 8:51 AM, ytbryan wrote: thanks for your reply thomas. for me, there is two cases of slowness. - the rpc is quite slow. i am using it to return a few thousand by eleven column of data(String) There are probably two issues here, one the speed of the RPC, and the second the speed of populating the table. But at issue is the attempt to return 33,000 cells worth of data in one shot. how much of this data is going to be immediately visible to the user? How likely is the user to use all of this data immediately? Does your use case present you the opportunity to fetch this data in some paged way? you need to figure out how much of your time is spent with the RPC (deserialization) and how much is spent rendering the table. I would be inclined to believe that you are likely to find that most of the time is actually spent rendering the 33,000 cells. however you do have some options here. You can move the rendering into an IncrementalCommand which will draw a few rows at a time which gives the appearance of a much more responsive application, and will begin rendering immediately, rather than waiting until all rows are populated before showing the data on screen. If your RPC data graph is pretty large, you could switch away from RPC and use a JSON data graph with Javascript Overlay types on the client side. a javascript eval() of the object graph from JSON is quite a bit (like orders of magnitude) faster than RPC deserialization with very large object graphs. NOTE your design shouldn't rely on large object graphs, paging is a much better option. And as gregor mentioned, if you are profiling your code in hosted mode, the performance has no correlation with real life. you need to check the performance in web mode, and remember that something that happens instantaneously in Firefox or Safari (or chrome) could take forever in IE (particularly IE6), its javascript engine operates at a glacial speed when compared to other options. thanks again.. good luck -jason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hi, Can somebody suggest me how to create a GWT Bar Chart or Pie Chart which get populated from Database dynamically by querying the database? The charts should get refreshed every 5 min. Also, which API to use in this regard. Any help is highly appreciated!

1.6 Compile problem on Mac OSX
Hi, I am using the new eclipse (3.4) plugin with GWT 1.6.4 on Mac OSX 10.5. Everything works great when my project is using Java 5 but when I switch to Java 6 and try to GWT compile I get the following error: Invalid memory access of location rip=01160767 This is a problem for me because I want to use a server side library that depends on Java 6. I have had a search through the issue log and the groups but haven't found anyone with a similar problem - am I doing something wrong? Does anyone know whether this is a known issue or a possible work around?

Re: GWT Serialization with CustomFieldSerializer fails because of SerializationPolicy

Re: Trouble with asynchronous calls
On Wed, Apr 15, 2009 at 1:22 PM, badgerduke badgerd...@gmail.com wrote:
Just started using GWT and I am having difficult tailoring my code to
the asynchronous nature of RPC calls. Specifically, my code asks for
the results of an RPC call before anything is returned.
Here is my class which calls a service. Instead of using an inner
class for the AsyncCallback, I use a separate implementation,
FormAsyncCallback, whose code is also below:
package com.gallup.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
public class FormService {
public String call(FormBean formBean) throws FormException{
FormRemoteServiceAsync serviceProxy = (FormRemoteServiceAsync)
GWT.create(FormRemoteService.class);
ServiceDefTarget target = (ServiceDefTarget) serviceProxy;
String serviceURL = GWT.getModuleBaseURL() + formservice;
if (GWT.isScript()) {
serviceURL = /Struts2GWT/formservice;
}
target.setServiceEntryPoint(serviceURL);
final String successMessage = null;
FormAsyncCallback callback = new FormAsyncCallback();
serviceProxy.setForm(formBean, callback);
if (!callback.isHadError()) {
GWT.log(A, null);
return callback.getSuccessMessage();
}
else {
throw new FormException(callback.getErrorMessage());
}
}
}
package com.gallup.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
public class FormAsyncCallback implements AsyncCallback {
private String successMessage = null;
private boolean hadError = false;
private String errorMessage = null;
public void onFailure(Throwable t) {
hadError = true;
GWT.log(, null);
errorMessage = t.getMessage();
}
public void onSuccess(Object result) {
GWT.log(C, null);
successMessage = (String) result;
}
public String getSuccessMessage() {
return successMessage;
}
public boolean isHadError() {
return hadError;
}
public String getErrorMessage() {
return errorMessage;
}
public boolean isReturned() {
return returned;
}
}
My problem is that AAA always prints before B or
CCC. I really want my code to wait for the RPC call to return
before I interrogate the results. Does anybody have suggestions?
Change your mind. No, seriously. Read
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/faca1575f306ba0f?pli=1
and then figure out how to redesign your app to be asynchronous.
Chances are you're going to want to pass an instance of an anonymous
inner class as the AsyncCallback and have it delegate in onSuccess or
onFailure to business logic somewhere else.
One thing that might help you is to think of RPC in an event-oriented
manner. You're presumably already comfortable handling button-clicks
and widget-focuses. Start thinking about RPC responses as events that
happen sometime after their corresponding requests. Build your app
around this line of thought and your life will be much easier.
Perhaps more importantly, your user's lives will be at least tolerable
(which they won't be if you force your RPCs to be synchronous).

Re: GWT 1.6, JSP's wont compile.
Wow, thanks for this tip! I've been meaning to explore App Engine, and this gave me even more reason to. I just tested it all out and it works like a charm.

Try actually adding a mouse click handler, not overriding onBrowserEvent.

@Override

dragging = false;
DOM.releaseCapture(getElement());

(basicaly an exact copy of whats in the class's over mouseup event).
However;
a) dragging is not visible error
b) It says onMouseUp is depreciated anyway and to use endDragging.
(Looking at enddragging;
protected void endDragging(MouseUpEvent event) {
onMouseUp(caption, event.getX(), event.getY());
}

But at issue is the attempt to return 33,000 cells worth of data in one shot. how much of this data is going to be immediately visible to the user? How likely is the user to use all of this data immediately? Does your use case present you the opportunity to fetch this data in some paged way? you need to figure out how much of your time is spent with the RPC (deserialization) and how much is spent rendering the table. I would be inclined to believe that you are likely to find that most of the time is actually spent rendering the 33,000 cells. however you do have some options here. You can move the rendering into an IncrementalCommand which will draw a few rows at a time which gives the appearance of a much more responsive application, and will begin rendering immediately, rather than waiting until all rows are populated before showing the data on screen. If your RPC data graph is pretty large, you could switch away from RPC and use a JSON data graph with Javascript Overlay types on the client side. a javascript eval() of the object graph from JSON is quite a bit (like orders of magnitude) faster than RPC deserialization with very large object graphs. NOTE your design shouldn't rely on large object graphs, paging is a much better option. And as gregor mentioned, if you are profiling your code in hosted mode, the performance has no correlation with real life. you need to check the performance in web mode, and remember that something that happens instantaneously in Firefox or Safari (or chrome) could take forever in IE (particularly IE6), its javascript engine operates at a glacial speed when compared to other options. thanks again.. good luck -jason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Two clients one session
Hi, Generally with J2EE serverside (or .net) your session object has a one to one relation ship with your user, it is communicated to the server one of two ways; 1) As a cookie (what your seeing with the session id in the cookie) 2) As a cgi parameter of the url (ie http://foo.com/index.html?jsessionid=987298429847) [for users who have cookies turned off] On the server the session is looked up and added to your HttpRequest (getThreadLocalRequest) object before your code (regular Servlet onService or rpc method) does anything. You can use the session paradigm to store state full information (like the users name Chris) when the protocol is stateless (http). If you don't need state full information just ignore the session api.

Hi, I would like some help to resolve this problem at the example of
GWT using Gdatastore:
http://code.google.com/webtoolkit/tutorials/1.6/appengine.html#data
All application run well following the getting start tutorial, so when
I try to improve using data store at this implementation an erro
occurs because stockService is not declare yet.
I tryed to force the declaration using StockService stockService =
GWT.create(StockService.class); but another erro is get with the
method getStocks.
private void loadStocks() {
stockService = GWT.create(StockService.class);
stockService.getStocks(new AsyncCallbackString[]() {
public void onFailure(Throwable error) {
}
public void onSuccess(String[] symbols) {
displayStocks(symbols);
}
});
}
private void displayStocks(String[] symbols) {
for (String symbol : symbols) {
displayStock(symbol);
}
}
If there is no mistake I would like to know where I can download the
caomplete example with datastore workings.

Re: erro while try to do Store data in the datastore Example
Yes, hitting the same problem. So far the example was great.
Outstanding in fact. Being new to Java I'm afraid I'm stuck

engine tutorial and fixed this issue on their own, any help would be
greatly appreciated. Or as the OP said, a complete set of the working
code would be nice as well.
