Re: MyNamedFrame is better than GWT's NamedFrame
As it turns out, IE does NOT support programmatically setting the
onload attribute of the iframe. The solution is to set the onload
attribute in the html tab to call another function, which is the
function you programmatically set.
My following post will include all the code for the new solution,
which works in ALL browsers (well I tested IE, FF and Chrome :P)

Hi, currently I create modules in order to access server-side classes
in my GWT client code. Until now all these classes have not referred
(directly or indirectly) to classes outside of the GWT JRE emulation.
However, now I need to be able to compile a bean with a reference to
javax.xml.namescape.QName. And in general I see how it might soon be
needed to compile classes with references to uncompilable classes
either because it's a third party class and we don't have the source
available, or it's a JRE class for which there's no emulation yet,
etc.
So I'm wondering if there's a way to use deferred binding to provide
the compiler with a client-side specific implementation of those
classes. The caveat of course is that the class containing the
offending reference to uncompilable code should not be changed. For
example:
class MyBean {
QName q;
MyBean(QName q) {
this.q = q;
}
}
Maybe something along the lines of ...
replace-with class=com.mycompany.gwt.bind.MyQName
when-type-is class=javax.xml.namescape.QName/
/replace-with
For what I read nothing of the like is possible, since for starters
the deferred implementation has to go through GWT.create(), but I'm
hoping there's another way I haven't thought about.
Thanks

Re: Help integrating GWT with existing Eclipse J2EE Tomcat project
Sorry, I don't have my development environment here, so I don't remember the exact details, but... You must run BOTH the Tomcat server and the GWT application in development mode. The trick is to configure the GWT application so it doesn't run the built in server, and use the Tomcat server instead. When run this way, the first time you launch the GWT application it will ask for the place where the web application is, you must point it to the Tomcat webapp directory used by Eclipse. This way you're also able to debug simultaneously the GWT and the JavaEE code. We've got such an environment, integrated with Maven. Sorry for giving such a few details...

Problem with RichTextEdit on Google Chrome (linux); works fine in other browsers.
Hi
I am working on an applivation, that includes a form, where I have a
textarea, that I can switch between using a TextArea, and a
RichTextArea. Everything works fine in Firefox (Linux and Windows) and
on Internet Explorer;
However when I try my application on Google Chrome (v6.0.401.1) on
SuSe Linux, I have some problems when in RichTextEdit mode. ( I find
it strange, that with a Google product like GWT, that they do not have
prober support for their own browser; when things are working fine in
other browsers)
1: The TAB key does not work.
2: OnFocus and OnBlur handlers are not called when entering/leaving
the RichTextArea (works fine on TextArea)
I am using GWT v2.0.3
the class is defined like this:
public class CslRichTextEdit extends Composite implements
ClickHandler, KeyUpHandler,
FocusHandler, BlurHandler {
I assign the handlers like this:
textArea = new TextArea();
richTextArea = new RichTextArea();
richTextArea.addFocusHandler(this);
richTextArea.addBlurHandler(this);
richTextArea.addKeyUpHandler(this);
richTextArea.addClickHandler(this);
textArea.addFocusHandler(this);
textArea.addBlurHandler(this);
textArea.addKeyUpHandler(this);
textArea.addClickHandler(this);
and the Focus/Blur handlers are created like this:
@Override
public void onFocus(FocusEvent event) {
if (rawMode) {
textbar.setVisible(true);
} else
toolbar.setVisible(true);
if (maxChars 0) {
cPanel.setVisible(true);
}
}
@Override
public void onBlur(BlurEvent event) {
if (rawMode) {
textBuffer = textArea.getText();
} else {
textBuffer = richTextArea.getHTML();
}
if (maxChars 0) {
cPanel.setVisible(false);
textSize = textBuffer.length();
if (textSize maxChars) {
Window.alert(Too many characters in textbox);
if (rawMode)
textArea.setFocus(true);
else
richTextArea.setFocus(true);
}
}
}

private void export() {
Object win = exportOpen();
// Actual code loops through data and writes lines, but for
example...
exportWrite(win, TEST,TEST,TEST);
exportClose(win);
}
This code basically works, except for the fact that the output is just
displayed in a new browser window without prompting the user with the
open/save dialog, which is what I was after.
Does anyone know how I can get the open/save dialog to be opened for
the user? Or, is there a way to create and download this data in GWT
without using native JavaScript?

Re: What's the best/easiest way of doing server-side persistence with GWT?
I just completed an application on the following stack - GWT, Spring and EclipseLink (JPA). From my experience, if you are using GWT 2.x and using annotations in your persistent classes, there is no need for Gilead or Dozer. Don't get hung up digging the net as most of the blogs/articles are outdated (for GWT 1.5 or 1.x) If you are developing your application as one big project, this is super easy and everything just works. There is no problem transferring objects from DAO layer all the way upto java script. (GWT 2.x knows how to handle it). But if you want to separate out your server side development you will have to package those transfer objects along with source as a jar and add them as gwt module(source is also required for gwt). Mine was a relatively small application and hence followed the first approach. But i did try out the second approach and it worked. (A simple build script will do the work for you) Thanks, Manoj On May 21, 8:44 am, José González Gómez jose.gonzalez.go...@gmail.com wrote: Can't help there, as I haven't tried it yet.

Re: Compiling classes that refer to uncompilable classes
DTOs and that it's good and useful, but I'm talking about compilation.
I want to be able to use a server-side class on the client GWT code.
Whether I need to pass it around between client and server is another
story. Right now I'm just trying to use it. The problem comes when the
class has fields that are not GWT serializable. In that case I'm
wondering if there's a way to use deferred binding (or something else)
to provide alternate implementations for those uncompilable fields'
types.
The base deferred binding obviously doesn't work since it's not a
straight replacement of a type for its implementation (it's more a way
to generate instances, and thus its use through GWT.create). But I'm
wondering if there's something more obcure that I have missed.
At least having an annotation (already proposed and logged in a ticket
http://code.google.com/p/google-web-toolkit/issues/detail?id=3769q=serveronly)
for the compiler to ignore such fields, would be a partial solution.
But I really wish there's a replacement option.

Hi, currently I create modules in order to access server-side classes

(directly or indirectly) to classes outside of the GWT JRE emulation.
However, now I need to be able to compile a bean with a reference to
javax.xml.namescape.QName. And in general I see how it might soon be
needed to compile classes with references to uncompilable classes
either because it's a third party class and we don't have the source
available, or it's a JRE class for which there's no emulation yet,
etc.
So I'm wondering if there's a way to use deferred binding to provide
the compiler with a client-side specific implementation of those
classes. The caveat of course is that the class containing the
offending reference to uncompilable code should not be changed. For
example:
class MyBean {
QName q;
MyBean(QName q) {
this.q = q;
}
}
Maybe something along the lines of ...
replace-with class=com.mycompany.gwt.bind.MyQName
when-type-is class=javax.xml.namescape.QName/
/replace-with
For what I read nothing of the like is possible, since for starters
the deferred implementation has to go through GWT.create(), but I'm
hoping there's another way I haven't thought about.

Re: What's the best/easiest way of doing server-side persistence with GWT?
Hello, I have completed a GWT / Hibernate / gilead / mysql project. It was my first, the whole process was a large pain but mostly worth it still compared to DIY. My newer project is based on GWT / Oracle DB Java edition an object based db. It has been too easy so far... no translators, just one or two non intrusive annotations on my Entities and persistent classes. Plus it can outperform SQL in a lot of aspects.

Re: What's the best/easiest way of doing server-side persistence with GWT?
Manoj, are you saying that Gilead is totally redundant for GWT now? That the problems mentioned on the Gilead page (LazyInitializationException, Eager-fetching etc.. ) never occur any longer? I couldn't find a gwt issue on the tracker that solved this, but was it ever an issue/needed?

There is no problem transferring objects from DAO layer all the way upto java script. (GWT 2.x knows how to handle it).

Re: Compiling classes that refer to uncompilable classes
On 20 mai, 23:16, Raziel raziel...@gmail.com wrote:
Hi, currently I create modules in order to access server-side classes
in my GWT client code. Until now all these classes have not referred
(directly or indirectly) to classes outside of the GWT JRE emulation.
However, now I need to be able to compile a bean with a reference to
javax.xml.namescape.QName. And in general I see how it might soon be
needed to compile classes with references to uncompilable classes
either because it's a third party class and we don't have the source
available, or it's a JRE class for which there's no emulation yet,
etc.
So I'm wondering if there's a way to use deferred binding to provide
the compiler with a client-side specific implementation of those
classes. The caveat of course is that the class containing the
offending reference to uncompilable code should not be changed. For
example:
class MyBean {
QName q;
MyBean(QName q) {
this.q = q;
}
}
Maybe something along the lines of ...
replace-with class=com.mycompany.gwt.bind.MyQName
when-type-is class=javax.xml.namescape.QName/
/replace-with
For what I read nothing of the like is possible, since for starters
the deferred implementation has to go through GWT.create(), but I'm
hoping there's another way I haven't thought about.
That's what super-source/ is about.

Re: MyNamedFrame is better than GWT's NamedFrame
hi sky!
that looks pretty much like our implementation...;)
this is the problem of such a big toolkit like GWT, there are too many
'features' (like widgets, rpc, jre emulation, java-to-js compilation,
the new data driven widgets and so on) which is great for a fast start
and even enough for many applications, but as soon as you get
creative, you have to start doing things by yourself, which is in my
expirience really hard with GWT since many, many (far too much)
methods and classes are private or final, so it is really hard to
extend the provided stuff, so at the end you finish hacking GWT and
building your own framework on top of the toolkit based on the core
feature, java-to-js compilation, which could be the idea.of the
developers, i do not know...
continue the good work!

Re: What's the best/easiest way of doing server-side persistence with GWT?
There are enhancements in GWT 2.0 to handle enhanced classes especially the ones related to persistence. Please see the section Serializing Enhanced Classes of http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideSerializableTypes As mentioned in their documentation, there still exists certain limitations, but see if they are relevant to your application. Also note that you need to add jpa-annotations-source.jar in gwt classpath. You can get it from here - http://code.google.com/p/google-web-toolkit/issues/detail?id=1830 Thanks, Manoj On May 21, 11:44 am, Ladislav Gazo ladislav.g...@gmail.com wrote: And how does GWT handle associations where Hibernate (as JPA implementation) puts own Collection implementations?

From my experience, if you are using GWT 2.x and using annotations in your persistent classes, there is no need for Gilead or Dozer. Don't get hung up digging the net as most of the blogs/articles are outdated (for GWT 1.5 or 1.x) If you are developing your application as one big project, this is super easy and everything just works. There is no problem transferring objects from DAO layer all the way upto java script. (GWT 2.x knows how to handle it). But if you want to separate out your server side development you will have to package those transfer objects along with source as a jar and add them as gwt module(source is also required for gwt). Mine was a relatively small application and hence followed the first approach. But i did try out the second approach and it worked.

I thank David for bringing it to my attention, it looks VERY interesting, and under active development, although the queries are currently reportedly slow, but when that is fixed, is there a reason why it shouldn't supercede RD and ORD for new projects?

Anyway, if you're handling complex object structures, it's way more cumbersome to handle persistence by hand, instead of using a ORM framework. If you want to have automatic update of the database, Hibernate tools is able to generate the database schema from your mappings. I suggest to take a look at Maven, Maven Hibernate plugin, JBoss Tools, and Spring Roo. Haven't worked with the later, but GWT has just made a coordinated release with Spring Roo and I think it may be quite interesting for you. I hope this isn't getting too much

Static Initializer behavior?
I have a situation where I think that static initializers are not
acting correctly.
I have distilled a simple example where I get different behavior if I
compile in Java vs when I am running in development mode (this is
using GWT 2.0.3). (I have not tried a production compile yet).
Given the following 2 classes in the same pkg, I get different results
in Java vs GWT when I invoke B.getFoo().
Java: B.getFoo() returns xxx
GWT: B.getFoo() returns null
Seems like since static initializers are supposed to be executed prior
to the class being available, that GWT is incorrect here?
Can anyone enlighten me if I'm doing something wrong or unsupported in
GWT?
public class A {
protected static String foo;
public static String getFoo() {
return foo;
}
}
public class B extends A {
static {
foo = xxx;
}
}

GWT Hibernate Project Structure
Hi, This is my first ever forum post. I really need some help with understanding how to setup a GWT 2.0 Hibernate3 project. I understand the GWT RPC mechanism and the problems with serializing Hibernate POJOs. I would prefer to use DTO's rather than Gilead or Dozer. So far, I have a Hibernate Project built with Maven2 in Eclipse using the m2eclipse plugin and the HibernateTools plugin for Eclipse. I also have a GWT 2.0 project built with the GWT plugin for Eclipse. I'm using MySql as the RDBMS. What I don't understand is how to setup, configure, and deploy the two projects in such a way that they can communicate with each other. Let's say with the above setup, I'm trying to persist a Person object that has only an id, and a name as fields. In my Hibernate project, I would create a Person.hbm.xml Hibernate mapping document, and then generate the corresponding Hibernate Java POJO and MySql table. Then, in my GWT project, I would create a serializable PersonDTO.java class that can be sent 'across the wire' to and from the server via GWT RPC. Then, for simplicity's sake, let's say that in the client package of my GWT project I create a CreatePersonService.java interface and a CreatePersonServiceAsync.java interface with one method, void createPerson(). I would then need a CreatePersonServiceImp.java class on the server side that implements createPerson(). Fine, but here's where I get confused. If the createPersonServiceImp.java class is going to transform a PersonDTO.java class into its Hibernate POJO equivalent, then it needs to utilize classes from both my GWT Eclipse project and Hibernate Eclipse project. So which project do I put it in? It needs to have access to GWT classes like PersonDTO, AsyncCallback and other RPC classes. It also needs access to Hibernate classes like SessionFactory, Transaction, etc. So it needs to have access to my GWT jars and Hibernate jars which are in two separate projects. How do do I link them so that CreatePersonServiceImp.java has access to all the libraries it needs. Finally, how do I correctly merge both of these projects into one WAR file for deploying onto a server? Or am I way off track? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-tool...@googlegroups.com.

Hi, the problem is that ScrollPanel apparently is not propagating the layout data, according to the explained here: http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html#Design A workaround is to remove position:relative style from ScrollPanel div.

How to navigate to particular tab of GWT automatically
I have a Module called Employer inside my app . The employer module has a jsp page to it called Employer.jsp . This Module builds various Parent Tabs and Child Tabs and Each Tab has its own data content rendered from different onModule Load on its own . Now I have a requirement like if the user is on the 2 child Tab and clicks on send message to a different user . Then I should be able to capture the link and send it across to the user . So when the second user sees the message and clicks on the link he should directly go to this tab . The message will be viewed within the app . Since there is only one module . i am not sure how to capture this link and send it across . Because when i take a look at the url it only says myappContextPath/Employer.jsp it does not say which Tab item is selected and so forth. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to navigate to particular tab of GWT automatically
The answer lies in com.google.gwt.i18n.client.Dictionary If the entrypoint module is reachable thro /MakeAGoodGuess/ Employer.jsp, then the url you could use is /MakeAGoodGuess/Employer.jsp/pg3. Presuming - you know how to parse the subpath of request url from the request object of the jsp page, - you know how to use java code in a jsp, - you are familiar with json construct a javascript tag enclosure and define a var as dictated by javadoc of gwt Dictionary class. That var would be a json structure contain all the info you wish to pass to the entrypoint module. But if you won't need to pass a whole load of params, you don't need a json structure but just var pg = 3; At the entry point onModuleLoad, use Dictionary to extract that var. Then just use TabLayoutPanel selectTab method to select tab 3. If you have a whole load of params to pass from jsp used to load the module to the entrypoint module, you might as well define a var assigned to a json structure. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Get date and time from java-javascript compilation
Hi Matheus, There might already be a built in way to do this, but if there is I don't know of it. There might also be a simple way to add an ant task to the regular eclipse plugin compilation process, since I believe it's just using ant under the hood. Within straight GWT land, though, the key is that you want to evaluate code at compile time and have the result available at run time. I would just write a really simple generator that generates a class to an interface consisting of just getCompileTime() (or whatever), which could be returned as a String or a Date object (from a String) if you need localization/more options/etc. If you've never written a generator for GWT before, the learning curve can be a bit daunting, but once over the concept is pretty simple, powerful, and a great way to get to know the real flexibility allowed by the GWT compilation process.

Re: How to navigate to particular tab of GWT automatically
Thanks for your answer I am a newbie . I am not still sure how to do this if you can provide me sample it would be great Let me explain it more This is what happens when the user hits the employer.jsp , what my app does is show all the employees who belong to a particular employer in a grid . When the grid 's row is clicked , we taket hem to a section where there are many tabs and child tabs . and each child tab has a a Icon next to it which would enable to user to create a message with this child tab link link . So next time lets say user b logs into the system and sees the message and hits on to the link the child tab should automatically open , starting from constructing the parent and the child tab and selecting the child tab .

Re: [gwt-contrib] STS RPC failures
[by the way, the second link you posted is broken]
Hm, this is odd. What actions are you taking (in the UI) when the RPC
exceptions happen?
The dialog that pops up for you to select your WAR directory is expected;
the default value is what you should choose. Can you send a text listing of
the files that are in that directory (plus subdirectories) during the
launch?
Also, you shouldn't need to specify --file expenses.roo; you should just
be able to type script expenses.roo, but I don't think that would make a
difference anyway.

Finder window and prompts me to select a WAR directory, which defaults
to target/extrack-0.1.0-SNAPSHOT.

Re: [gwt-contrib] STS RPC failures
Oh, also, did you enable AspectJ weaving (when STS asked you about this)?

Hm, this is odd. What actions are you taking (in the UI) when the RPC
exceptions happen?
The dialog that pops up for you to select your WAR directory is expected;
the default value is what you should choose. Can you send a text listing of
the files that are in that directory (plus subdirectories) during the
launch?
Also, you shouldn't need to specify --file expenses.roo; you should just
be able to type script expenses.roo, but I don't think that would make a
difference anyway.

Somewhere in here, don't you need to rewrite things like new
JsoSubtype[3] to new JavaScriptObject[3]?
Also, what about visitVarInsn for storing into locals/params, and
visitInsn for storing into arrays?

Does a cast to JavaScriptObject require the canonical object? Or just

This is shocking enough to be worth a comment, that reference equality

like this:

turns into something involve jumps.

[gwt-contrib] Re: Fixes pathological slowness in remote UI logger (GPE) (issue550801)
This is definitely something that Rajeev should look at since I didn't have much to do with this part of it. On a relatively superficial look everything looks ok, but it seems like there should be tests that explicitly cover all the cases of trying to log branches/messages to a logger before the top logger has come back across the wire. http://gwt-code-reviews.appspot.com/550801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
