Re: GWT Special Features compared to other Frameworks
Hi, 1 point related to your point 1: java means compilation, i.e strong type checking at compile time (even at write time if you use Eclipse that compiles in real-time). The difference in productivity is huge 1 point related to your point 3: you can not only integrates runtime frameworks but also dev tools to improve quality of code (FindBugs, JUnit, Checkstyle, etc.) regards didier On Jan 18, 10:05 pm, Ryan Mehregan wrote: > I am afraid your first point is not a correct assessment. > "Programming the Web" is a very broad category > which encompasses a plethora of Java Web Frameworks that emerged over > the past decade many of them now obsolete. > Like many of the MVC frameworks > (Struts, WebWork, Tapestry, SpringMVC/WebFlow, Wicket, Play, JSF), > or specific components of MVC such as View technologies for MVC. > ( template engines such as Velocity, Freemarker, Tiles, SiteMesh) to > name a few. > > therefore you need to explain how GWT compares with those and why and > when to use GWT instead of all those Java Web Frameworks ? > > and in addition, your point does not address what is the benefit of > using Java to program the web ? > there are many many alternative frameworks, programming languages out > there. why choose Java ? > > > 1.

Re: can I use Class.forName and newInstance in GWT ?
Hi,
You can't: if you go to
http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html#Package_java_lang
for Class, you will see that forName() is not emulated by GWT.

Re: GWT must Allow sending a variable of type object via RPC
Hi,
Does the object you want to send implement Serializable ? It's
required
Then in your case when not just define
class MyObject extends Object implements Serializable {
...
}
Then, you will be able to carry MyObject and its child classes over
RPC.

Re: Class is not serializable ?
Hi,
you have to use non-generic definition for GWT:; i.e. Class and
then probably implement a DTO (Data Transfer Object) if you want to
keep the Class on server-side and have just Class on
client side. That's how I do it personnally.

Re: Class is not serializable ?
Hi,
Serializable is an interface not a class. That's why it's not the list
you mention. An interface has nothing to be serialized per se.
You should let us know about your class MyType in order to better
help.

Re: Using external Jar in GWT project
Hi, The error message says it all: GWT transcodes Java to Javascript. So, instead of adding jar in classpath, you have to add the source of the library to your own source in order to have it transcoded by the GWT compiler. Warning though: GWT compiler has a limited support of Java Runtime. See the list at http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html. So, if your library using unemulated classes or methods, you'll have to find another equivalent library or change the one you want to use. regards didier On Dec 11, 11:08 pm, Çağdaş wrote: > Hi all; > > I'm new in GWT and i'm trying to use jena that is a semantic > framework.

Re: sending Polymorphic types from Server to GWT client
Hi, It's possible: did it several times. The key is to use GWT-RPC (instead of JSON, xml, etc..) in order to preserve all the Java structure between client and server. How ? a) You will define Foo, Bar, Baz in the "shared" folder of project structure so that they know on both sides b) you will define either 1 generic RPC query/request for the 3 object types (easy if you have a parent class on top of your 3 classes) or 1 RPC query/request per object type. c) GWTRPC will deliver those objects as Java objects (when you code) so you can use then "instance of". To make things simpler, you can even use the RequestFactory of GWT 2.1 Preserving Java semantics end-to-end is for me the best part of GWT: you can leverage the power of object hierarchies, interfaces, etc. in your front-end. The simplest way to achieve this is GWTRPC that allows transparent transport of objects between client and server. regards didier On Dec 10, 11:00 pm, zixzigma wrote: > I have three objects, that implement a base interface and reside on > the server. > > interface Base > class Foo implements Base > class Bar implements Base > class Baz implements Base > > I want to send them over the wire to GWT client. > > would GWT recognize the relationship they had ? > > I want to use them in CellTree: NodeInfo > and would like to do something like > > if (value instance of Foo) > /// > > if(value instance of Bar) > /// > > if(value instance of Baz) > /// > > is this possible ? > how ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: using Guava, CommonBeanUtils, Apache Commons in GWT
Hi, a) You need the source code so that GWT can translate it to JS -> should be no issue for open source libraries b) Those libraries have to restrict themselves to classes and methods of those classesemulated by GWT -> that's probably gonna be hard to respect for rich libraries. The emulated part of the JRE is defined here: http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html If (b) can't be satisfied and you want anyway to stick to those libs, you have to use GWTRPC to make requests from your client to those libraries hosted on the server and then use RPC back for the results. The other way is to fork the libraries (if licence permits) to adapt them to the GWT emulation if possible. regards didier On Dec 10, 11:44 pm, zixzigma wrote: > is it possible to use third party Java utility libraries, such as > > -Guava > -Apache Commons/CommonBeanUtils > -Data Structure Algorithm libraries (for Graph/Tree algorithms:eg. > JUNG) > > in GWT ? > > I know that if they use Reflection it cannot be used, > > but for the ones I mentioned, > > and in general Utility Libraries/jars. > > is it possible ? > do they work ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: add gwt to existing Java project
Hi, GWT works very well with servlets: you can use the GWT-RPC to transfer objects back and forth between front- and back-end without going through JSON and the like. You can then transfer complex object structures / collections between both sides. Is your back-end server servlet-oriented? Anyway, GWT is a very good choice for front-end when back-end is also java: you enjoy then a great technological homogeneity between both sides and can also leverage the great java tooling (findbugs, junit, etc.) for your front-end regards didier On Dec 7, 2:48 pm, Andrew Balakhanov wrote: > Hello. > Could you please help me.

Re: help with stack trace
Hi, You should use "Output style = detailed" when translating to JS: your files will get much bigger but the source in js will be very easy to match with its java equivalent.

Re: ACL in GWT
Hi Baloe, You should definitely implement security in the back-end rather than in the front-end: you have to keep in mind that your back-end may be called by something else than your js code generated by GWT. You're then in bad shape if your back-end services accept any request without checking. So, make sure that the framworks / mechanisms that you use respect this. regards didier On Nov 24, 1:33 pm, ep wrote: > hi, you might want to take a look athttp://code.google.com/p/gwt-security/ > orhttp://code.google.com/p/acris/ > > On 24 Nov., 11:56, Baloe wrote: > > > Hi all, > > > I wonder what is the best way to put ACL in our GWT project.

Re: Default value for @RemoteServiceRelativePath ?
Hi David,
You can achieve what you want by using ServiceDefTarget of GWT.
Here below some code snippet of mine dynamically creating a detailed
url (instead of the basic one done by the annotation) to allow better
monitoring: I put some info (object id, etc.) in the url to monitor
more efficiently
So, check the ServiceDefTarget object in GWT dev kit: it will provide
you what you need.
ServiceDefTarget def =
(ServiceDefTarget)GWT.create(ServerObjectGetService.class);;
String url = RELATIVE_URL + "/" +
Util.getSimpleName(object.getClass());
if (object instanceof RpcRefinable) {
url += "/" + ((RpcRefinable)object).getSubUrl();
}
def.setServiceEntryPoint(url);

Re: What should I learn , Google Web Toolkit or Jquery ?
Hi, My 2 cents: a) learning curve for GWT higher than JQuery b) You can't work efficiently with GWT if you don't master html, http, javascript anyway... c) GWT is great because you come back to compile mode: your code is correct much faster and you don't have to write lots of unit test to confirm that nothing wrong happens at run time when you change your app in the more risk env of an interpreted language (js) d) GWT is also great because you can leverage the best equipped language in terms of tooling: Java for unit tests (Junit), quality measurement (findbugs, pmd), code coverage (cobertura), profiling, etc e) with GWT, you don't deal with the broswer type at all (at least in theory...) so you code faster f) if back-end is java also, you face a single technology for the client and the server side -> more manageable and simpler to handle by a single person. But, I agree with what was said before: the ticket to entry is bigger. So, probably not suited to a small app. regards didier On Nov 19, 3:34 pm, massimo malvestio wrote: > In my opionion it depends on the complexity of your project. > If you have to write a webapp / site with a complex interface that it has to > be feeded with a large amount of data, or you want to reserve the capability > to scale, and you have a couple of weeks to study gwt, choose gwt. > If you have not time enough to learn gwt, or, you don't need to manage > complex data exchange between client and server but you want an eye candy > web gui, learn jquery, it's quite easy to learn and use and you got tons of > plugins ready to be used. > I use both of them anyway, because, in my opinion, they are complementary, > use the weapon more suitable for the size of your target :-P -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hi You really should give a second chance to GAE: - space can go very high if you are willing to pay as you go - document upload is possible via BlobStore (I do it in one of my apps) - I would emphasize extremely detailled monitoring for which i know no equivalent by other hosters.

Re: GWT client-side thread or asynchronous call ?
Hi, Traditional javascript (to which gwt java gets converted) architecture is basically mono-thread in terms of real concurrent execution: so, gwt has to stay mono-thread also.

Re: Plans for GWT incubator
Hi John, The new jar that you point to here above still produces the same warnings as the older ones when using scrolling tables as listed below.

Re: Problem with Google App Engine
Hi, Think I understand now: you want to use the class on client side (i.e. within he browser) and you did put it in the client directory. Right ? Then, GWT wants to compile it to Javascript. At this point,2 solutions: a) either you provide the source of the class or b) you inherit the javascript from a module compiled by somebody else. I think none is possible in your case: you'll have to find another design without your Swing class: tell us what your purpose is and we may help. regards didier On Nov 16, 10:36 pm, Shawn Brown wrote: > > What is the error? > > Are you sure javax.swing.* is supported in GWT? > > Shawn -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to diagnose IE8 javascript error "stack overflow at line: 0"? ends up in Impl.entry0

Re: How to diagnose IE8 javascript error "stack overflow at line: 0"? ends up in Impl.entry0
Hi, I don't know enough about your appl but we had similar issues: that was due to complex data structures that we were bringing back to the client from the server over the GWT RPC -> we had to simplify the structures (carrying simple arrays of objects rather than complex graphs over RPC) in order to avoid the stack overflow caused by GWT- RPC serialization/deserialization. You may have a look in that direction too. Hope it helps. didier On Nov 5, 8:22 pm, BrianP wrote: > I have a GWT 2.0.3 app that runs fine in Firefox and Chrome.

content to deliver . Later on, the servlet handler to which you give
the response (incl the stream) back will flush it back to the
browser.

Re: Testing GWT?
Hi, I would recommed 2 steps: - using GWTTestCase included in GWT itself: http://code.google.com/webtoolkit/doc/latest/tutorial/JUnit.html. Very useful for the developper - If you need to run external tests totally independent from dev env, I would then go with Selenium. More to be used by some QA team. I use personally both according to my needs regards didier On Nov 4, 2:06 pm, g_korland wrote: > Can you recommend a testing tool for testing GWT web app? > > Thanks, > Guy -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Database data and GWT applications
Hi Owen, Did you also install the Google App Engine part of Google SDK on your Eclipse? Then running and debugging a database-oriented application gets easy and efficient: the SDK has a Jetty (i.e Tomcat-like) in it. So, you can fully test locally and test deploy as easily on App Engine infrastructure. So, give a try to the full package and come back if any question: I really find the combination GAE + GWT highly powerful for large scale and at the same time very efficient to develop + debug on a single machine regards didier On Nov 3, 6:20 pm, OS wrote: > Hello, > > This is my first posting here so I'm sorry if all this has been > covered before. > > I've come to GWT from a J2EE background.

Hi Ray, To answer your second question, I would suggest using Google App Engine in addition to GWT: you can deploy right away to GAE (with no infrastructure on your own) after your local test with 127.0..0.1 tests.

Re: about compilation of java.util even when not included
Hi
JavaUtil may be included because 1 of the gwt components that you use
(HTML, RootPanel, etc.) may need id.
To figure it out, you should compile with GWT in detailled mode, then
find out the name of js code for java.util and search it throughout
the entire code of your application to see where it is used

Re: Hook up HTML with GWT
Hi Il Lupo,
I guess that you want to replicate what is usually done in js but you
want to do it natively in Java: the way to go is to use
com.google.gwt.dom.client.Node (or Element)
If you know the html id of your element, then you can get it and start
iterating over its children to reach them as needed all in Java: check
the doc above.

Re: Datastor issues - persistent POJOs
Hi Will,
I developped some mechanism based on reflection API to qutomatically
do gets from Objectfiy pojo and sets to client pojo when going from
server to client and gets from client pojo to sets of server pojo
when going from client to server. This avoids me typing all this code
and making errors (forgetting props; etc.)

Re: Datastor issues - persistent POJOs
I personally use the clone technique: i.e a simple pojo with no
annotation.
You may later on face a second issue with your annotated objects if
their methods use server side specific objects or methods: the
emulated part of JRE in gwt is fairly small: see doc.
so, separating client and server sides is probably better on the long
run.

Help for testing GWT.UncaughtExceptionHandler within a JUnit GWTTestCase
Hello,
To improve the coverage of my automated tests, I'd like to test my own
GWT.UncaughtExceptionHandler within a GWTTestCase to see if it
functions correctly.
I can't do it for now: the JUnit test always fails.
Can you help me an let me know what's wrong in my code below ? (I
tried to use an asynchronous test to make sure that I am going through
the ExceptionHandler)
thanks

public class TestExceptionHandler extends GWTTestCase {
public void testWithHandler() {
ExceptionHandler handler = new
ExceptionHandler(GWT.getUncaughtExceptionHandler());
GWT.setUncaughtExceptionHandler(handler);
this.delayTestFinish(1000);
throw new ClientException("test");
}
private class ExceptionHandler implements
GWT.UncaughtExceptionHandler {
private GWT.UncaughtExceptionHandler handler;
public ExceptionHandler(GWT.UncaughtExceptionHandler h) {
this.handler = h;
}
@Override
public void onUncaughtException(Throwable e) {
System.out.println("Exception handler called!");
TestExceptionHandler.this.finishTest();
this.handler.onUncaughtException(e);
}
}
@Override
public String getModuleName() {
return "MyModule";
}
}

Re: Developing RIAs with GWT
Hi Noor, If you really want to demonstrate the capabilities of GWT, you have to include images & graphics with various layers on top of each other. Else you will end up using the GWT in their plain (although sophisticated) form: we developped for our company such an application (e-tearsheeting for newspapers based on full-page images with overlays - positionned with 1px precision) on top of the newspaper page delineating the ads and coloring them if they were ok or not according to the initial order). That was quite a challenge and would have been very hard without gwt I can send you some screenshots so that you can better see what I means around this graphical complexity with overlays .

Hi, I think that you're having a Google App Engine Problem rather than a GWT problem: the class that you mention is not the white list of Google App Engine. Hence the exception. http://code.google.com/appengine/docs/java/jrewhitelist.html If your plan is not to run you app on Google App Engine but on a regular java server, than the issue comes from the setup of your project (uner Eclipse) where you probably ticked the GAE box when defining it, then Eclipse included the gae environment.

Re: Datastore
Hi Trevor, I would suggest giving also a try to Objectify which a layer on top of raw Datastore: it makes access to data much easier and has a lower learning curve than JDO. See http://code.google.com/p/objectify-appengine/ (have a special look at wiki pages) I moved away from JDO for Objectify and I am very satisfied with it. didier On Sep 24, 5:17 pm, David Chandler wrote: > You can use any of GWT's client / server protocols to connect to a > servlet running on App Engine that in turn calls the Datastore.

Re: can't find my GWT version
Hi, the static method getVersion() on class GWT (so GWT.getVersion()) gives it programmatically. So, if you put your jars alternatively in your classpath, you will find the version of each of them didier On Sep 23, 9:31 pm, Viktoriya Sokolova wrote: > Hi. > > I have a few GWT jars I am using, but I cannot find what version of > GWT it is.

Re: GWT - javascript result is not encoding correctly!
Hi Rodrigo,
Do you work with Eclipse, if yes verify File > Properties > Resources

This property has to be set to UTF-8.

Re: Why is getOffsetWidth/getOffsetHeight returning 0 even after onLoad is called for LayoutPanel children?
Did you check if you have the issue on all browsers: I have it on
Webkit based browsers (Safari + Chrome) but not on IE and FF.

"Duplicate case " on switch statement by GWT compiler
Hi everybody,
I need to escape utf-8 to their html format.
I use the function below and the gwt compiler to JS doesn't like it:
it says "duplicate case" for all cases starting with and after the
à
a) Can somebody tell me what I am doing wrong ?
b) Is there any better way (using official GWT code) to do it ?
thanks
