Re: What is 'final' keyword for?

Hello, everybody!
In HasDataPresenter.java I see code like this:
// Update the page size.
final boolean pageSizeChanged = (pageSize != length);
if (pageSizeChanged) {
pageSize = length;
}
and later
if(pageSizeChanged)
doSomething();
What a reason to use 'final' keyword here? Dos it help to produce
better java script?
No. It's a clear intent that pageSizeChanged should not be changed
after it is set. If someone does change it the compiler will tell you.
Final is very important in Java. Look it up!

Re: How to get the unexpected exception thrown by backend component onthe client side
Hi
(There's no need to copy my personal email address. Please do not).
What we do is this.
1. We have a custom RuntimeException:
public class ServerSideException extends RuntimeException implements
IsSerializable
{
private static final long serialVersionUID = 1L;
@SuppressWarnings(unused)
private ServerSideException()
{ /* For GWT. */ }
public ServerSideException(Throwable t)
{
super(t);
}
}
which can be seen by the GWT compiler and is declared on ALL RPC methods.
2. All of our RPC endpoints are spring beans.
3. We have a simple throws advice:
public class RpcErrorAdvice implements ThrowsAdvice
{
private static final Logger log =
Logger.getLogger(RpcErrorAdvice.class); //NOPMD
public void afterThrowing(final Throwable t) throws Throwable
{
log.error(t);
throw new ServerSideException(t);
}
}
4. which listens to all beans derived from RemoteService:
bean class =
org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator/
bean name = rpcErrorAdvice class =
net.purpletube.cerberus.server.springintegration.RpcErrorAdvice /
bean class
=org.springframework.aop.aspectj.AspectJExpressionPointcutAdvisor
property name = advice ref = rpcErrorAdvice/
property name = expression value = execution(public *
com.google.gwt.user.client.rpc.RemoteService+.*(..))/
/bean
That's it.

Re: How to get the unexpected exception thrown by backend component onthe client side
Hi It seems that all beans derived from RemoteServiceServlet should be listen to, but not RemoteService? Yes, if you have beans that inherit from RemoteServiceServlet.

Whoever you are, if you can't do it quickly I volunteer to take over the responsibility for it and make sure it is in within a couple of days. If I get to do it it, I'll also create a new googlecode repository for the nightlies for people to version range over if they wish.

GXT Button Id
Hi All We want to introduce Ids to our GXT components so that our interface is easier for testers to test. We thought it would be as easy as this: final Button sendButton = new Button(Send); sendButton.setId(ButtonId.send); RootPanel.get().add(sendButton); but this gives us: table cellspacing=0 role=presentation class=x-btn x-component x-btn-noicon id=ButtonId.send ... button style=position: relative; width: 31px; type=button class=x-btn-text tabindex=0Send/button ... /table As you can see the Id is added to the table in which the button is displayed. Is there a way to get it added to the actual button, so we can have: ... button style=position: relative; width: 31px; type=button class=x-btn-text tabindex=0 id=ButtonId.sendSend/button ... -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Client Session Timeout

Re: RPC Endpoints and threads
Hi Sri Thanks for the fast response, that was really useful! Thanks Paul On Thu, Apr 15, 2010 at 9:48 AM, Sripathi Krishnan sripathikrish...@gmail.com wrote: Servlet containers typically make only one object of your Servlet. This object is shared across several threads. Several threads is a configurable property on most servers, but usually varies between 15 to 30. If you have 100 users connecting simultaneously, the server will not start 100 threads - the remaining requests will be queued. But multiple threads sharing the same Servlet (or end-point, as you put it) object does not usually matter. That is, if you follow servlet best practices. The GWT RPC Servlet is Stateless. Even if 1000 users access it at the same time, it is OKAY - they will not interfere with each other. When you write a RPC Servlet extending RemoteServiceServlet, you should also ensure that it is stateless. There are several ways to do it, but the easiest is to NOT use member variables in your ServiceImpl. Users in different sessions are also serviced by the same Servlet object. It is up to you to handle them differently by reading from the Session object and taking a different action for each user. And, just to go a step further, the recommended approach is to not use sessions. That gives you opportunities to scale later. EJB's are a complicated beast and meant to solve an entirely different class of problems. Even if you already use EJBs in your project, you should still write a RPC Servlet that delegates the heavy-processing to EJB. --Sri On 15 April 2010 13:19, Paul Grenyer paul.gren...@gmail.com wrote: Hi All I've been thinking a lot about the GWT RPC mechanism and from the tests that I've done it appears that the same endpoint instance is used for every RPC call.

Re: Integrate GWT with Windows Applications
Hi I would like my GWT application to communicate with a Windows Application. on the presentation layer. It is no problem to start the Windows Application. Something that works using a special URL redirect. Now I wonder how both can communicate at Runtime: 1) The GWT App needs to know when the other application finishes. 2) The GWT App needs to receive return parameters from the other application. I had two ideas in mind, but I don't know whether this will work. 1) Let them communicate over a shared temporary file 2) Use some sort of AJAX-Magic Is there any common approach? Any experiences? Any help appreciated! I suspect web services is the way to go, especially if you can embed some sort of server in your Windows app. If you Springify your GWT app, you can expose web services that the windows app can call. Then if you expose web services in your windows app, you can make a GWT RPC call that then talks to the windows app. -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Is IsSerializable depreciated?
Hi All
I was under the impression that IsSerializable was depreciated in
favor of Serializable. However, I've just created a new exception
type:
package uk.co.marauder.usermanager.client;
import com.google.gwt.user.client.rpc.IsSerializable;
public class ServerSideException extends RuntimeException implements
IsSerializable
{
private static final long serialVersionUID = -1005766244333245684L;
@SuppressWarnings(unused)
private ServerSideException()
{}
public ServerSideException(Throwable t)
{
super(t);
}
}
and it won't serialize across the RPC boundry unless it implements
IsSerializable, Serializable doesn't work.

Re: Is IsSerializable depreciated?
Hi
Jesper,
any access modifier for the constructor can be used. This is
documented and I tested id.
Me too.
http://code.google.com/intl/en/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideSerializableTypes
「Serializable User-defined Classes」
…
3. As of GWT 1.5, it must have a default (zero argument) constructor (with
any access modifier) or no constructor at all.
I really like this feature as it means I don't have to give my classes
an accessible default constructor unnecessarily.
Paul,
I think I cannot serialize Throwable, but you can do that with
IsSerializable.
That could well be it.
I want to know the service method you define.
public interface UserService extends RemoteService
{
User find(String username) throws ServerSideException;
void save(User user) throws ServerSideException;
}
http://code.google.com/intl/en/webtoolkit/doc/latest/FAQ_Server.html#Does_the_GWT_RPC_system_support_the_use_of_java.io.Serializable
Another important point to note is that none of the classes that implement
java.io.Serializable in the full Java JRE implement java.io.Serializable in
GWT's emulated JRE.
What this means is that types that implement java.io.Serializable in the JRE
like Throwable, or StackTraceElement won't be able to transfer across the
wire through GWT RPC since the client won't be able to serialize/deserialize
them.
Yes, that seems consistent with my tests. However, I would expect
IsSerializable and Serializable to be interchangeable. e.g.: this:
public ServerSideException extends RuntimeException implements IsSerializable
to be the same as
public ServerSideException extends RuntimeException implements Serializable
but it appears they are not.

And I get the same error: Unknown argument: -portHosted Google Web Toolkit 2.0.0-rc2 DevMode [-noserver] [-port port-number | auto] [-whitelist whitelist-string] [-blacklist blacklist-string] [-logdir directory] [-logLevel level] [-gen dir] [-codeServerPort port-number | auto] [-server servletContainerLauncher] [-startupUrl url] [-war dir] [-extra dir] [-workDir dir] module[s] where -noserverPrevents the embedded web server from running -portSpecifies the TCP port for the embedded web server (defaults to ) -whitelist Allows the user to browse URLs that match the specified regexes (comma or space separated) -blacklist Prevents the user browsing URLs that match the specified regexes (comma or space separated) -logdir Logs to a file in the given directory, as well as graphically -logLevelThe level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL -gen Debugging: causes normally-transient generated types to be saved in the specified directory -codeServerPort Specifies the TCP port for the code server (defaults to 9997) -server Specify a different embedded web server to run (must implement ServletContainerLauncher) -startupUrl Automatically launches the specified URL -war The directory into which deployable output files will be written (defaults to 'war') -extra The directory into which extra files, not intended for deployment, will be written -workDir The compiler's working directory for internal use (must be writeable; defaults to a system temp dir) and module[s]Specifies the name(s) of the module(s) to host I assume I must be doing something wrong in my install? Having to manually copy the SDK took me rather by surprise.

Re: GWT 2.0.0rc2 ::: Unknown argument: -portHosted
Hi All
I should really know by now, that the Internet is a wonderful, wonderful thing!
On the page I quoted:
http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC
there is a comment, currently second from bottom, on November 23rd by
a.revolution.ultra.blue, which states, in response to another
comment that has the same problem the people in this tread are having:
--BEGIN---
YES! You CANNOT use the google g-icon web app run menu, you need a
plain jane java application runner, with main class
com.google.gwt.dev.DevMode??
Make sure you have the usual program arguments for a gwt project; mine
are: -port -startupUrl / ai.yx.xSeed
I have / set to a welcome servlet in web.xml, and my gwt project is ai.yx.xSeed
If you want to use appengine, you will also need to add the program
arguments and vm arguments I mentioned in the post above. ALSO, if you
do NOT use appengine, leave the working directory at default. If you
DO use appengine, add /war to whatever your default directory is... My
project xBook uses ${workspace_loc:xBook}/war
If you absolutely can't get it to go, just download ms2 from the
deprecated dl page, and you can go ahead and use the old google-plugin
launch configuration.
--ENG--
So, I am now a little further. I have a Java Application Run
Configuration that uses com.google.gwt.dev.DevMode as the Main class
and has the arguments: -port Gwt2RC2 (my project is called
Gwt2RC2).
However, i still have a problem when I run it:
[ERROR] Unable to find 'Gwt2RC2.gwt.xml' on your classpath; could be a
typo, or maybe you forgot to include a classpath entry for source?
I've tried fiddling with the classpath and source settings of the Run
Configuration, but so far nothing's worked. Does anyone know what I'm
doing wrong?

Re: GWT 2.0.0rc2 ::: Unknown argument: -portHosted
Hi Thomas 5.Then copied gpe-e35-1.2rc1.zip\eclipse\plugins to C:\Program Files (x86)\eclipse\plugins 1) Why are you using 1.2rc1? it won't work with GWT 2.0.0 RC2 wrt the - portHosted vs. -codeServerPort naming change. There you go. I was obviously suffering brain fade and really not paying attention. Thank you for pointing that out. 2) Why not just unzip it in C:\Program Files (x86)\eclipse\dropins as you're told to do? Go easy! :-) ...because the first time i tried it, it didn't work. Seems to work perfectly now. It may well have been due to me having the wrong plugin. 6.Then copied the contents of gwt-2.0.0-rc2.zip to gpe-e35-1.2rc1.zip\eclipse\plugins Why are you putting it within your eclipse install? Was fighting int he dark. I'm no eclipse expert and that's where it seemed to be in the previous plugin. I've now moved it. See above: you have to use the RC2 version of the plugin with the RC2 version of GWT. Thanks! :-) All workign now.

Forwarding to TomCat
Hi All This may be entirely the wrong place to ask this question, but I'm hoping someone here has done something similar. If anyone objects to this I am more than prepared to desist. What I want to do is this: 1. Host Apache or IIS on an externally facing server and have it serve static things like images and (GWT) JavaScript. 2. have IIS/Apache forward requests for HTML pages (which are served up via Spring MVC on TomCat), RPC calls and webservice requests to TomCat on an internal machine (presumably through a firewall with the appropriate port open). This will give me a number of things: 1. Better security 2. Move the serving of the big stuff from TomCat to Apache/IIS Any help greatly appreciated. -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: @SuppressWarnings(serial)
Hi Don't the Servlets need to have a serial version ID in case the server decides to passivate them?

Re: @SuppressWarnings(serial)
Hi As there are far better ways of doing that sort of thing, I guess that Servlets should be stateless and therefore don't need to be Serializable.

Hi in my initial client-server application I want to read a file, lets say 'index.txt', which I then want to pass to the client as string. Everything seems to be fine, however I get a file exception. So my question is, what is the server root directory at run-time? I tried several locations below 'war' but none of them helped. So can you tell me the path where 'index.txt' has to be installed, please? You should be able to get it form the ServletContext. -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com w: http://www.marauder-consulting.co.uk b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: The following classpath entry '...' will not be available on the server's classpath
HI 2009/7/30 Miguel Méndez mmen...@google.com: If you want to use the libraries on the server, then they should be in WEB-INF/lib. Yeah, I don't. These ones are just for testing. The warning has a quick fix that will do that for you. If you really don't want these on the server then you can add the .settings folder to your version control system once you have excluded them. Yeah, I don't fancy that much, especially as the projects are shared. We've discussed having an errors/warnings configuration page like the one for the Java compiler. This seems like another reason to do so. That would be perfect. Is there a feature request I can create or add weight too? -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com w: http://www.marauder-consulting.co.uk b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Google Web Toolkit and JavaMail API
Hi I'm working on a web application using Google Web Toolkit (GWT). This application should have some mailing functionality. Therefore I have decided to use Java Mail API. I start by importing the Java Mail API to my bulid path. The file is called mail.jar. Then I import the mail package into the class by using the import statement (import javax.mail). Then a problem occurs if I test the application in hosted mode. I get the following error message: [No source code is available for type javax.mail.Session; did you forget to inherit a required module?] After a bit of research I figured out that I have to inherit another module into by modifying the XML file. The problem is simply that I can't figure out how to name the module correct. Is there someone who can help in order to solve the issue. Your email suggestes that you're trying to send email fromt eh client side, is that right? I don't beleive GWT can do this, so you'll need to make an RPC call to ther server... -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com w: http://www.marauder-consulting.co.uk b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Portal with Dynamic Menus and Views
Hi Dave Thank you very much for your response. I have a similar situation for my project. What I do is make the first async call from onModuleLoad() do something like 'getPortalAttributes'. This returns to me info from the server like: is the user logged in; is the application in development mode; if the user is logged in, what are their permissions. From there I generate menus based on the user's permissions, and configure things like the GWT.UncaughtExceptionHandler. Of course, your application shouldn't trust any permissions logic that is applied on the client, but determining what menus to show is harmless for me. That makes sense, but I think I'd prefer not to have that logic in the front end. A different approach is to return the menu structure from the server based on a users permissions. This is more interesting! What would you actually pass back? An XML structure from which to build the menu? How would you then hook it into method calls or events to the controller? -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com w: http://www.marauder-consulting.co.uk b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Portal with Dynamic Menus and Views
Hi All My company are working on an enterprise application with GWT, Spring and Hibernate. We've successfully integrated Spring Security, Spring MVC and GWT, but we want to display menus and associated views based on role and are wondering the best way to do this. To give an example of what I mean, if a normal user logs in they're presented with the user's menu in the left hand panel. If an administrator logs in they're presented with the user's menu and the administrator's menu. We could of course make an RPC call after the user (or administrator) logs in and only display the relevant menus based on logic in the GWT code, but we'd prefer to move the logic and the code for that to the server side. Is there a way? Something else we'd like to do is have optional, at deploy time, menus and views. Is there a way we can plugin such things? -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com w: http://www.marauder-consulting.co.uk b: paulgrenyer.blogspot.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Subject: RPC Issues - Lifespan of Data from a RPC
I tried to find this topic already on the discussions but could not
find it.
Currently using GWT 1.5.3
I am making a RPC to call to read XML and call a function that loads
the data into an ArrayList of classes. I have made a class that
implements RequestCallback(LoadData) and takes in my mainClass
example:
LoadData loadData = new LoadData(this);
String url = xmlString;
RequestBuilder requestBuilder = new RequestBuilder
(RequestBuilder.GET, url);
try {
requestBuilder.sendRequest(null, loadData);
} catch (RequestException ex) {
//Window.alert(exception);
}
Inside the RPC class:
mainClass.addProducts(id, sku, name, catagory) ;
inside my main class:
public addProducts(int id, int sku, String name, String catagory) {
productArrayList.add(new product(id, sku, name, catagory);
}
But when I call a method on my productArray it just says index out of
bound (basically the arrayList is empty) but I know it is calling the
addProduct method
I am guessing the lifespan of the data is tied to the lifespan of the
RPC call.
What sort of things can I do to get around this(assuming my
assumptions are correct)?
I greatly appreciate the help and apologize if this topic is covered
somewhere already.
