Re: Compiling from command line - Annotation errors
You have to javac your classes and give both the *.class and *.java to the GWT compiler. This is why it works in Eclipse: because Eclipse automatically compiles your source files, and the output folder is added to the classpath of the GWT Compiler.

I've google around a ton and can't seem to find any solutions. It's funny because it compiles no problem in Eclipse, but trying to compile on the command line has been a pain.

Re: RequestFactory in a offline Szenario?
Best thanx. Szenario 1, would mean that you have to deal with two
different sets of data structures online = entityproxies and offline
something else. or you have to develop your own layer above request
factory which to avoid was the rational behind using requestfactory.
Szenario 2 seems like a interesting approach, but i must confess i not
knowlegable enough of the internals of Requestfactory to really be able to
see what that means. Also for adressing the issue with the potential
confict resolution this is probably not the right layer
So probably you need something above RequestfFactory, which deals with a
higher level batching and offline / online awareness etc...

should be used. So I would not store the specific requests, but only the
data (along with some meta data like timestamp, isDeleted, etc.).
So its pretty much:
if(online) {
// requestfactory
} else {
// use local data cache
}
I am not sure if its possible to implement a custom RequestTransport for
RequestFactory, e.g. OfflineRequestTransport, that parses the RF payload
and executes/applies all the invocations/operations locally using a local
data cache. If it would be possible you could switch to an
OfflineRequestTransport as soon as you are offline and you dont need that
if(online) block everywhere in your code.

Re: Are you happy with GWT?
Some examples of pushback when trying to introduce GWT into a legacy j2ee application 1) We don't have time for a re-write 2) this is a website not an application 3) servlet template engines are sufficient for most UX and the rest can be done in javascript 4) SEO requirements 5) I18n stuff needs to be in our familiar message.properties 6) UI designers don't want to live in hosted mode It's my observation that most J2EE developers who fight against GWT change their minds when they are asked to write jquery or native javascript. You'll however have to provide them with a easy way to inject gwt components into their servlet templates. Some things to consider: 1) consider consuming a smaller portion of a servlet template rather than the whole page 1a) design your MVP end to support a servlet template containing multiple sections earmarked for gwt (as independent widgets or working in unison) 2) add comments to the serlvet template file to reveal the entry point or presenter that will be boostrapped when the page loads 3) use http page requests instead of Place management when jumping around to new locations ( a single entry point with MVP and code splitting works very well with this model) 4) Use UIB templates!!! 5) demonstrate the ability to Junit test presenter logic ( mockito , jukito ..) - in contrast to the 10s of thousands of lines of .js code that go unwatched David On Tue, Oct 9, 2012 at 6:05 AM, Richard richard.wat...@gmail.com wrote: A couple warnings.

TextArea vs RichTextArea
I am trying to create an area and initially I used the RichTextArea in order to use functions like toggleBold, toggleItalic and toggleUnderline. After a few days I noticed that in comparison with the TextArea, there are no getCursorPos and getSelectedText methods which are very essential in order to handle my editor. Do you know if there is any way to combine these functionalities or how can I use getCursorPos and getSelectedTextin in RichTextArea?

Re: GWT Properties file configuration
One way to do this is to add your server's .properties values to the page
in the form of a javascript map
script type=text/javascript language=javascript
prefetchedJSP[prop1] = ${prop1};
prefetchedJSP[prop2] = ${prop2};
/script
and then access those values in gwt with
a com.google.gwt.i18n.client.Dictionary
dictionary.getDictionary(prefetchedJSP);

I want to setup the configuration at client package because all
configuration belongs to client side.
My actual need,
I have one textArea which takes up only fixed number of characters and
length is defined in my properties file like below.
So I have to read a properties file for validation.
my.properties

smsConstraintCharLimit=160
I found few link but all are talking about properties file regarding

I want this file to be loaded at startup or at Entry point itself and then
I can use it at any client package classes for my validation.

That's a very interesting situation. Actually, this is a decision between full-ajax site and js-enhanced site, and for that question it doesn't even really matter which JS framework is used. Server-side templating has always been a somewhat crazy idea (a hack, if you want - but then again, AJAX is a hack, too). It's surprising, that GWT can handle even this scenario well, and although it can't show its full set of advantages then, it's still a great choice. It's possible with GWT to eliminate server-side templating, if you want, because GWT makes it so easy to move the UI logic to the client. There are simply things that should live on the server side and things that should live on the client side. With traditional web development techniques, this decision was biased - now you can make a balanced decision.

Re: Are you happy with GWT?
When servlet engines first came on the scene , developers were writing stringified content directly to the HttpResponse. There were also some popular widget frameworks at the time. Server side templating was introduced to let web designers into the fray. I wouldn't consider it a hack. Eliminating them completely has always been a tough sell. Luckily GWT does not require this .

How to include 3rd party libraries in a reusable gwt library/widget?
GWT Lovers, I'm trying to get my feet wet with GWT to see if migrating will work out. I usually try the more difficult parts first to make sure I can finish the project.

Right now I just put the reference to the external scripts in the html page in the project, but I'm pretty sure this is incorrect from a reusability perspective, as this lib would be used in other projects, each of which would have their own base html page. I tried putting the reference in the gwt.xml file, but this seems to lose the references (ie my test project no longer works as it did when the scripts were in the html page) Do you have any tips on how to include 3rd party libraries in a reusable gwt library/widget?

changing the style of a menu bar
Hi,
I would like to adopt the menubar style from the GWT Showcase example and I
copied the CSS code into my css. But it does not have any effect.
My hostpage includes the CSS:
link type=text/css rel=stylesheet href=bcs.css
And the CSS contains the menubar styles (see below).
The menu is created by code with some helper methods (see below).
The CSS has no effect, even if I change some colors or something like that.
Where is the problem?

Use Elemental to optionally generate HTML on the server?
I have a large GWT app which unfortunately is slow in some old browsers I need to support (IE7). A major part of the slowness is my architecture - I am using GWT-RPC to download model objects from the server and then building a large HTML table in the browser using GWT Widgets. The table is not fancy - just text, links, and images - but it can get pretty big. I'm considering fixing this by building some of my HTML on the server and then downloading it over GWT-RPC as a string, and injecting it in to the DOM using setInnerHtml(). I will still have to do some manipulation later in the browser though (my UI refreshes periodically in the background). What I would really like would be to write my code in such a way that I could decide at runtime if it was best to build the table on the server or in the browser. Elemental looks like a promising way to do this - it would not be hard to generate a server-side implementation of the Elemental HTML interfaces that built up an HTML string, and then send that string over the wire to be injected in the browser. My application logic would only interact with the Elemental interfaces, so I could decide at runtime which implementation to use. Does this sound reasonable or am I barking up the wrong tree here? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

When I run the same test using the GWT eclipse plugin, it works
without a problem. My Junit task is very simple:
target name=run-gwt-tests
mkdir dir=${build}/testresults /
junit printsummary=yes haltonfailure=yes fork=true
classpath refid=test.class.path /

batchtest todir=${build}/testresults
fileset dir=${test}
include name=**/ui/JUnit*.java/
/fileset
/batchtest
jvmarg value=-Xmx512m /

So presumably this is a classpath problem. The testing doc (http://
code.google.com/webtoolkit/doc/latest/DevGuideTesting.html) says it
should include:
Your project's src directory
Your project's bin directory
The gwt-user.jar library
The gwt-dev.jar library
The junit.jar library
Which my test.class.path includes (I have double checked with -v)
Anybody have any ideas or seen something similar? It's not the 2 Ant
versions is it? I am currently using Junit 3.8.1 rather than JUnit 4,
but presumably that isn't the issue either. Thoughts gratefully
received.

Absolutely, from that point of view (and I remember cgi scripts), template engines are a big enhancement to what existed before! But imagine telling developers from a different field, who have never looked into web development before, that there's - one approach that is based on sending the complete same htmlhead.../headbodydiv.../div/body over and over again, after using a template to replace just a small part of it. - and there's a second approach that just gets the necessary data from the server, and then updates the view (making use of the specific client's features) Which one would they choose? I believe it might be a hard time arguing in favor of the first approach. Eliminating them completely has always been a tough sell. The only significant technical argument against full-ajax is probably the SEO argument.

Re: Use Elemental to optionally generate HTML on the server?
I'd give CellTable/DataGrid a try, if your model is suitable for it and your cells aren't so 'fancy'. You can use async requests, paging and lightweight widgets (cell widgets); should be more than enough to speed up fetching/rendering time. There is also the ElementBuilder API that makes easy to create DOM elements from chaining calls in a builder fashion. Checkout some examples in http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/javadoc/com/google/gwt/examples/dom/builder/ . One interesting point is that you can use such builders also on server-side (the server-side actual implementation uses string manipulation instead of DOM operations) and send back the generated string to the client (never tried though) http://gwt-code-reviews.appspot.com/1455802/ Also AFAICT Elemental does not work well (or at all) with IE prior to 9.

A major part of the slowness is my architecture - I am using GWT-RPC to download model objects from the server and then building a large HTML table in the browser using GWT Widgets. The table is not fancy - just text, links, and images - but it can get pretty big. I'm considering fixing this by building some of my HTML on the server and then downloading it over GWT-RPC as a string, and injecting it in to the DOM using setInnerHtml(). I will still have to do some manipulation later in the browser though (my UI refreshes periodically in the background). What I would really like would be to write my code in such a way that I could decide at runtime if it was best to build the table on the server or in the browser. Elemental looks like a promising way to do this - it would not be hard to generate a server-side implementation of the Elemental HTML interfaces that built up an HTML string, and then send that string over the wire to be injected in the browser. My application logic would only interact with the Elemental interfaces, so I could decide at runtime which implementation to use. Does this sound reasonable or am I barking up the wrong tree here? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to include 3rd party Javascript libraries in a reusable gwt library/widget?
That's quite an old version. When you see a link like that, you should replace 1.6 with latest to jump to the current version, like this: https://developers.google.com/web-toolkit/doc/latest/DevGuideOrganizingProjects#DevGuideModuleXml For an external javascript file, you can add the file to the public directory of a GWT module and write code to insert the script tag into the DOM. In GWT, we have ScriptInjector [1] to do this, but that's just a wrapper - you could do it yourself. You will need to construct the URL of the javascript file to load. The GWT.getModuleBaseForStaticFiles() method [2] is useful for this. - Brian [1] http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/core/client/ScriptInjector.html [2] http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/core/client/GWT.html#getModuleBaseForStaticFiles() On Tuesday, October 9, 2012 8:53:13 AM UTC-7, Charlie Youakim wrote: Boy it's hard to find documentation in GWT out of the basics, but I found this which helps QUITE A BIT!

I usually try the more difficult parts first to make sure I can finish the project. The most difficult part of my project(s) is referencing 3rd party JS libs. In this example I'm trying to use PubNub as much of our platform uses it. What I'd like to do is create a reusable object that can be used in other GWT projects in need of PubNub. I've got a simple little test running successfully (ie, I've got the basics of JNSI working), but my question is - where do I put the reference to the 3rd party script in order to create the library/module properly? Right now I just put the reference to the external scripts in the html page in the project, but I'm pretty sure this is incorrect from a reusability perspective, as this lib would be used in other projects, each of which would have their own base html page. I tried putting the reference in the gwt.xml file, but this seems to lose the references (ie my test project no longer works as it did when the scripts were in the html page) Do you have any tips on how to include 3rd party libraries in a reusable gwt library/widget?

Tomcat Deployment Error
I am developing a GWT app and running into a strange deployment error. The app runs hosted inside the jetty server in eclipse. The app runs in debug in the jetty server in eclipse. The app runs in Tomcat, when being externally debugged by Eclipse. However, the app will not run at all in Tomcat without a debugger attached. It sits at the default page and throws a javascript error: java.lang.UnsupportedOperationException: get not implemented in JS I see no errors in the Tomcat logs, even with the log level turned up. I have replicated the issue across several environments, so it is definitely some failure of my code, Tomcat, GWT, or just the interaction of the three. The archives seem to have a lot of works in jetty but not in Tomcat, and I have tried most of the solutions with no success. Has anyone run into an issue like this?

Re: GWT-Textarea Problem
textArea.setText(textArea.getText() + newText); should let you append the data. To get data continuously you'll either need to poll the server, which will be expensive if you have many clients, or use something like long-polling to push data from the server to each client as it's generated. That'll be more work, but it's probably the right way to do it. Maybe poll for now, and then add comet when you have time. http://code.google.com/p/gwt-comet/ for one implementation of the client side.

Re: Are you happy with GWT?
Wow, I am impressed how much attention such a simple and non-technical question got. But then again, I am about to give my own opinion so why am I surprised :) Of course I am not happy with gwt itself, that would mean I am content with it the way it is, whereas there are so many improvements I can imagine ;) ( by the way, if you haven't already done so, please take time to participate in the gwt survey http://bit.ly/GWT2012) Having said that, I really do believe that choosing gwt was smart, because it has the potential to redefine what we believe a web application to be. I am pretty sure soon no one will be able to distinguish between web, mobile ,application and website. And Google will once again, just like for the web in the good ol' times, have a helping hand in this;) Realistically speaking, developing a gwt app RIGHT NOW is just about as messy as tinkering with js/HTML/CSS directly, where you trade having to deal with browser-specific bs for having to deal with gwt-specific quirks. This is of course my own opinion ,but it might be noteworthy, that I came as a Java Application developer to gwt and most of CSS /js issues still feel like black magic to me. But those are rather issues with my lack of knowledge ( scattered ,incomplete, outdated,contradictory or simply wrong documentation seems to be norm in web dev) than with gwt itself. Thanks for asking this question, if it isn't already it should be part of gwt survey ;) Oliver -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Immediate validation of editor field
Thomas, Thank you, as always, for your thoughtful reply. I wonder how you get any real work done with your dedication to this forum. I suspect you get a bit less sleep than me. The flush technique works fine. I even managed to craft a little editor visitor that passes a flush command to editors that want it (those that implement HasFlushCommand) so that they can request a driver flush (on a value change) without knowing anything about the driver. With that, I can have generic UiBinder-compatible validating editors that are capable of displaying immediate errors, like: e:ValueBoxEditorDecorator ui:field=priorityEditor e:valuebox v:ValidatingIntegerBox ui:field=priorityValidator / !-- so that the app can set properties (min, max, immediate or whatever) -- /e:valuebox /e:ValueBoxEditorDecorator I don't think it strays too much from the spirit of the editor framework. Thanks again. On Monday, October 8, 2012 9:33:33 AM UTC-5, Thomas Broyer wrote: On Monday, October 8, 2012 3:56:57 PM UTC+2, RickL wrote: There is a workaround, but it is not very elegant. You can do a driver.flush() in a change handler for the field you want to validate on-the-fly which, of course, re-validates (i.e. calls getValue()) on all fields. That seems to me a bit like swatting a fly with a sledgehammer. It would seem better to have, perhaps, another recordError method signature like: void recordError(String message, Object value, Object userData, boolean immediate); When immediate is true, the driver would immediately post the error to the nearest super-Editor that implements the HasEditorErrors interface, rather than waiting for a driver flush(). Thoughts? Don't try to abuse the Editor framework for use-cases it's not meant to fulfill. What you actually want is some widget that validate the field as soon as possible and displays the error if any, *and* integrate with the Editor framework so that any detected error will also be reported to the EditorDelegate. Either that or flush() at each change. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Saving results from GWT-RPC call on client
I was wondering if there's anyway to save the returned results from an RPC call to an HTML5 enabled browser. Basically the only way I have found would be to convert the results into strings and use LocalStorage to save them to the browser. I guess my question then would be how can IsSerializable java objects be converted to a string and back. Any help would be appreciated.
