Re: Google Maps 1.0 Library access to native underlying GMap2 object ...
Thread closed and resolved!
I like to put that because some thread have plenty of answers but you
sometime don't know if it has a solution ;)
Maybe it would be a suggestion to google forum developpers to had a
feature to have the capability to mark the state of the thread (open,
resolved , )
Thanks.

Re: passing parameters from JSP to GWT
Why is it not secure to pass parameters from client side (whatever that actually means...)? I say the second method of defining a GWT Dictionary in JSP is the easiest way. Or, instead of GWT Dictionary, use javascript overlays: define a custom javascript object in the page, and access it through javascript overlays. Advantage is type safety, and autocomplete. ~Chii On Jan 11, 4:31 am, wera svet...@gmail.com wrote: Hi All, I am adding a GWT component in JSP. It should receive several parameters to know how to present data (for example, how many buttons should be, what is the selected value in a drop-down, etc.) The question is how to pass parameters from JSP to GWT.

I saw 2 ways: -define in JSP a GWT Dictionary to contain a map of values that GWT component needs -add parameters on request - in include of GWT noscript.js What is the best practice? thanx --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

YAJRSQ (Yet Another JPA Related Serialization Question)
Greetings GWT experts, Sorry, it's yet another post on the topic of serializing entities retrieved from a JPA provider. In this case I'm using Toplink on Glassfish which hasn't been addressed too much in these discussions yet. I'm retrieving an object called OperatingSystem from the JPA layer and trying to pass it to GWT. Toplink does bytecode instrumentation to add a field called _toplink_flavor_vh (type oracle.toplink.indirection.ValueHolder). Predictably GWT barfs with: Caused by: com.google.gwt.user.client.rpc.SerializationException: Type 'oracle.toplink.essentials.indirection.ValueHolder' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized. Theoretically I could add the source for ValueHolder as a GWT module in order to make it serializable, but since _toplink_flavor_vh is not really part of my bean I'd rather it be treated as transient and skipped completely. The compiled javascript version of my object won't have the instrumented field on the client side anyways, so serializing and transmitting the values of _toplink_flavor_vh over the wire is a waste. So here's my question. Is there a way for me to get the field _toplink_flavor_vh to be treated as transient when my OperatingSystem object is serialized (remember that the source code for OperatingSystem.java does not contain the field so I cannot add the transient keyword; the field is added later by Toplink via bytecode instrumentation). Is this a scenario for a custom serializer? (a crude hack would be to treat any field beginning with underscore as transient, which I think would work for all Toplink-added fields) (Incidentally, I tried using Dozer to make a detached copy of my object, which I think works with Hibernate, but since Toplink is adding fields directly to my class, even a detached object created with new OperatingSystem() has the TopLink field. I've only been able to succeed by creating separate DTO class, which I'd like to avoid if possible. In any case it feels redundant to make a deep clone of my objects just before GWT-RPC does a deep serialization of them) Looking forward to your thoughts!

Re: Getting java.net.SocketTimeoutException: Read timed out
Hello All,
I have same problem, using JBoss AS. The most interesting that this
situation occurs only and ifonly I have a very big delay when tracing
the route host i.e. something like 1400ms. I have tested my
application from many locations in the world today but only from one
where the connection seems to be unstable I had such a problem. Here
are my connector settings:
Connector port=8009 address=${jboss.bind.address}
emptySessionPath=true enableLookups=false
redirectPort=8443
protocol=AJP/1.3 maxThreads=400
connectionTimeout=60
compression=force
/
Following the documentation :
http://www.jboss.org/file-access/default/members/jbossweb/freezone/docs/2.1.0/config/printer/http.html
it seems that keepAliveTimeout = connectionTimeout = 60 = 10 mins
I have lost all the day fixing this problem but nothing can be done
unfortunately. Any help is appreciated!
Best Regards,
Pavel Tonev

then you will have toreadthe apache docs and edit the settings in
your web.xml (possibly keep alive) although with the default
settings of 1min before timeout this is unlikely.
Hope this helps,

Is it because of long executing methods? The error message clearly
reads that it is a timeoutexception. My guess is some operation on
server is taking more time than your timeout values set.
For a better answer, give us more information.

UI Binder
Hi guys. According to tis blog entry http://googlewebtoolkit.blogspot.com/2008/12/whats-ahead-for-google-web-toolkit_10.html long-awaited UI Binder extension will be released soon. But the main question is WHEN ? Originally October of 2008 was stated as planned release date, then after NYE holidays and finally last thing I heard was will be released this week. Considering that UI Binder is heavily used (according to member of GWT team) inside Google is there any real estimate when it's going to be published ? Beta version is fine, it's enough to try it out. I'm also curious where it will be published - in GWT incubator project or as new release of GWT ?

Re: passing parameters from JSP to GWT
Hi Chii, Thank you for your suggestion Why client side solution is not secure? Because in JSP the presentation logic was hidden in server. And if I pass all the parameters to GWT via JavaScript, everyone can play with it by changing HTML source. On Jan 11, 2:34 pm, Chii sangohan@gmail.com wrote: Why is it not secure to pass parameters from client side (whatever that actually means...)? I say the second method of defining a GWT Dictionary in JSP is the easiest way. Or, instead of GWT Dictionary, use javascript overlays: define a custom javascript object in the page, and access it through javascript overlays. Advantage is type safety, and autocomplete. ~Chii On Jan 11, 4:31 am, wera svet...@gmail.com wrote: Hi All, I am adding a GWT component in JSP.

Serialization problem
Hi people.
I've been developing an application with hibernate + spring + gwt, and
i've come to a point where i need some help from you!
I know that hibernate generates PersistentBag for Lists ( Hibernate
implementation of List), and I need to serialize this lists. But I
know that GWT doesn't support PersistentBag.
So, and because i've read that we can implement a custom field
serializer, i developed a PersistentBag_CustomFieldSerializer, like
this:
package org.hibernate.collection;
import com.google.gwt.user.client.rpc.SerializationException;
import com.google.gwt.user.client.rpc.SerializationStreamReader;
import com.google.gwt.user.client.rpc.SerializationStreamWriter;
/**
* Custom field serializer for {...@link
org.hibernate.collection.PersistentBag}.
*/
public final class PersistentBag_CustomFieldSerializer {
public static void deserialize(SerializationStreamReader
streamReader, PersistentBag instance) throws SerializationException {
int size = streamReader.readInt();
for (int i = 0; i size; ++i) {
Object obj = streamReader.readObject();
instance.add(obj);
}
}
public static void serialize(SerializationStreamWriter
streamWriter, PersistentBag instance) throws SerializationException {
int size = instance.size();
streamWriter.writeInt(size);
for (Object o : instance) {
streamWriter.writeObject(o);
}
}
}
With this development, the server serializes the instance, with no
error, but the client return's a message saying
This application is out of date, please click the refresh button on
your browser.
Could anyone provide with possible hints to solve this error.
Best regards
Hugo Marcelino

Re: UI Binder
Hi, The UI Binder is currently listed under the Post-1.6 timeframe.

Re: Focused training/consulting?
I don't think there is any way to make things compile much faster. I think the real question is why you think you need hundreds of modules. Does your website really need hundreds of small RIAs? I cannot think of too many situations where this would be needed. I have used JPA and GWT in an application before without too many problems but not Spring (the app was a standalone RIA). Although debugging is a nice GWT feature it is not its strongest advantage - the organized OO-method of UI web design and AJAX integration are by far the most important aspects of the toolkit. Regards, Matt On Jan 9, 5:29 pm, Steve Anthony stephencanth...@gmail.com wrote: Hi, My engineering team took the last month to use GWT to implement new pages for our UI. We had a world of trouble around interactions with Spring Hibernate. It was bad enough that the main GWT advantage (productivity increases from easier debugging) was not realized. Likewise, we had some issues around compilation speed, 1-2 minutes to compile a single module, for example. Think hundreds of modules, and this isn't going to scale. I'm looking to see if there are any recommendations for people who could provide a _focused_ training session; a few days to help us understand how to work the technology interactions so that we can improve our productivity. We know the basics; but are having trouble adapting the technology into our stack and making effective use of it. Recommendations gratefully welcome.

Re: ThreadLocal support
I think code re-use is the only valid scenario right now. For example, a previously developed component that could otherwise be compiled to JavaScript by GWT cannot because it uses ThreadLocal.

Re: can gwt work with javax.swing.* ?
GWT gets translated to Javascript. Now, you might argue So? I heard Swing is pure Java. Why can't SWING by translated by the compiler to JS? The answer is because while Swing is pure Java, it is layered on top of AWT which is anything BUT pure Java. Thinking SWT? Don't go there. Like Swing it also uses native methods (real native methods (calls to C code), not JSNI) too. Where Swing and SWT ultimately make calls to native heavyweight platform specific components, GWT makes calls to the browsers dom handling interfaces via Javascript. db On Jan 10, 2:31 pm, mikedshaf...@gmail.com mikedshaf...@gmail.com wrote: OK, one of the things that you have to wrap your head around is how GWT works. You write GWT using Java, but then the GWT compiler converts this into Javascript HTML. It can only do this to Java that it specifically knows about. Your Swing JLabel component is not something GWT understands and therefore it can't compile it out into Javascript. The strength of GWT is that you develop in Java, but if your code is going to be run in the browser, it has to be Java that is compatible with the GWT Compiler. Hope this helps.

Re: Multiple web pages how-to
You are still thinking in the classical web development paradigm. You should start thinking web2.0 now! The concept of multiple pages and they linked with each other through form submits or hyper link clicks etc is gone now! Now your entire application is a module with a single entry point and it loads in one single page. Once loaded every thing happen in that same page... popups, tabs, button clicks, hyperlinks, form submits, table render, data fetch, insert, updates, etc, etc all happens in that same page. However, as per gwt's philosophy you can break your application into multiple functional groups called modules. Modules will load in separate pages and can link to each other using classic hyperlinks or other methods. But for most purpose your entire application will be one page! With that said, there is no default back/ fwd or history related functionality build in your application as you are not navigating through data any more. To accomplish this behavior, gwt has provides History api. You can use the History api and events to simulate the back/fwd and bookmark functionality. It is a little tedious, but the good news is you get all the control over difficult to manipulate browser functions. I am sure you will learn these concepts through practice. Hope that helps!

Re: GWT vs. Adobe Flex for UI development when J2EE/Spring is used for middle tier/server programming
That really depends on what you're trying to do. If you want to build a multimedia website that's going to have a lot of video streaming and audio, then you're better off with Flex. However, if you want a snappy and clean web application, you're better off with GWT. I haven't been particularly impressed with the performance of Flex websites. Even large websites like http://parleys.com are slow on my brand new MBP on a 1 MB/s connection. And while Flex is the perfect candidate for Parleys, I definitely wouldn't want web applications I'm working on to be that slow. -- Arthur Kalmenson On Fri, Jan 9, 2009 at 4:32 PM, j2ee_nyc success...@yahoo.com wrote: Flex is a bit of an anomally, it's not Javascript really, but it's not Java based either. When it comes down to what the choice is it's simple: is it valuable to your development process to have a second language stack in your solution? If your server side is Java, your client side is either Javascript or Flex (is it still called Actionscript, it's been a while). Or you write your server in Java AND your client in Java, and allow your compiler to optimize the client code to it's application container...that's what GWT does. Plain and simple. I think the main issue with any framework that generates JavaScript is that it remains a JavaScript solution behind the scenes. Therefore, it retains the limitations of JavaScript and some issue with browser compatibility. Seems that Flex tries to accomplish something similar to Java Applets by providing a solution that works from within a plugin (Flash). Logically, that seems to give Flex a much more power UI that can potentially perform and work better than any JavaScript solution. So, that would be my question: are Flex developers so excited because the hype of cute UI, or because they believe that Flex is a better long term solution than any JavaScript based solution, be that GWT, Dojo, JQuery, etc.? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

If you're looking for a good book to cover real world use of GWT, check out Pro Web 2.0 Application Development with GWT by Jeff Dwyer and published by Apress. -- Arthur Kalmenson On Sun, Jan 11, 2009 at 10:34 AM, asianCoolz jim.the...@gmail.com wrote: is such tutorial available? i glanced through some of the existing, most will either teach you to create calculator, or explain about theory. none of them actually teach you step by step to create web app with user login form, shopping cart..etc... can anyone recommend good 1.5 tutorials? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Does Google offer GWT consulting services?
Not that I know of, but there are a lot of developers who are willing to offer GWT consulting services. I believe Jason Essington is one of them. -- Arthur Kalmenson On Sat, Jan 10, 2009 at 10:19 PM, David E. dve1...@gmail.com wrote: Does Google provides GWT consulting services and/or is there a Google approved list of GWT consulting companies? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Focused training/consulting?
Hi Steve, 1. I concur with Matt that the biggest advantage of GWT is writing AJAX client in Java instead of javascript - if you are writing a large application then this will pay off hand over fist in the long run. 2. Start up troubles depend on the direction your team come from. Java people tend to have trouble with CSS and HTML rules, whereas javascript/HTML people tend to have difficulty getting OO and Java rules. What you've got is really good toolkit but you have to learn how it works to use it well. 3. I don't think there are any major difficulties in addressing Spring from GWT RPC servlets - there are numerous resources on that around - but there is an issue with Hibernate (and any other ORM/JPA system). The problem is that ORM frameworks support lazy loading and to do that they adorn your persistent domain classes with various proxies and special collection classes which the GWT JRE Emulation Library does not support. Secondly there are things that need to be considered regarding attaching/detaching persistent objects for transfer to client during long running transactions. You will definitely want to look into this and select your optimum approach up front - there is more than one, and the best one depends on your exact situation. A good place to start is hibernate4gwt/Gilead. If you understand how that works you will have your head around the issues and be in a good position to evaluate options. Hibernate4gwt stores original Hibernate objects in HttpSession, and it would be nice not to have to do that, so quite a lot of people role their own custom RPC serializers to speed things up, but in general they have worked out in advance that it will work OK for them. Others use a DTO creator library like Dozer for the same reason, i.e. to help make server as stateless as possible. I would be careful about this lest it bite you on the backside. Search group for numerous posts on the subject. 4. I don't think the number of modules makes a whole lot of difference to compilation speed - I think it's the LOC count that really matters since it's the conversion of Java code to javascript that takes the time. There are several things you can do get to situations where developers are waiting seconds rather than minutes to run/debug their edits, for example: a) In case you don't know, if you are editing just client side code you do not have to recompile, you just hit refresh in the dev shell browser which takes seconds to respond. If you change, say, RPC sevlet code (basically anything running on the server) you do. b) If you temporarily specify a particular user-agent (i.e. browser) in the main module gwt.xml file, the compiler only creates one set of client files (instead of four) and that cuts compile time by about 50%. c) If you have a big application then splitting the client into modules is a good idea and means you can develop and test individual components separately using separate temporary/test entry points. You pay for that with extra integration work, but it will obviously significantly cut down day to day compile times so it may be worth it. regards gregor On Jan 11, 11:01 pm, medgey matt.egyh...@gmail.com wrote: I don't think there is any way to make things compile much faster. I think the real question is why you think you need hundreds of modules. Does your website really need hundreds of small RIAs? I cannot think of too many situations where this would be needed. I have used JPA and GWT in an application before without too many problems but not Spring (the app was a standalone RIA). Although debugging is a nice GWT feature it is not its strongest advantage - the organized OO-method of UI web design and AJAX integration are by far the most important aspects of the toolkit. Regards, Matt On Jan 9, 5:29 pm, Steve Anthony stephencanth...@gmail.com wrote: Hi, My engineering team took the last month to use GWT to implement new pages for our UI. We had a world of trouble around interactions with Spring Hibernate. It was bad enough that the main GWT advantage (productivity increases from easier debugging) was not realized. Likewise, we had some issues around compilation speed, 1-2 minutes to compile a single module, for example. Think hundreds of modules, and this isn't going to scale. I'm looking to see if there are any recommendations for people who could provide a _focused_ training session; a few days to help us understand how to work the technology interactions so that we can improve our productivity. We know the basics; but are having trouble adapting the technology into our stack and making effective use of it. Recommendations gratefully welcome.

According to tis blog entry http://googlewebtoolkit.blogspot.com/2008/12/whats-ahead-for-google-web-toolkit_10.html long-awaited UI Binder extension will be released soon. But the main question is WHEN ? Originally October of 2008 was stated as planned release date, then after NYE holidays and finally last thing I heard was will be released this week. Considering that UI Binder is heavily used (according to member of GWT team) inside Google is there any real estimate when it's going to be published ? Beta version is fine, it's enough to try it out. I'm also curious where it will be published - in GWT incubator project or as new release of GWT ?

Re: step by step to build entire web app with gwt1.5
You can pick up some of the web app parts from these tutorials. I don't think any of them deal with building a login based web app directly but in bits and pieces they can give you the direction that you might need: In the order of preference: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=GettingStartedTutorial http://www.ibm.com/developerworks/java/library/j-ajax4/ http://www.softwaredesign.co.uk/gwt.html I think that if you have created the sample stockwatcher of google, you will cover most of the ground required for creating a basic app and you can build on that. regards, Saurabh. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: can gwt work with javax.swing.* ?
Hi, Though what you are saying is perfectly right there are on going efforts in Eclipse 4.x (short e4) to provide an SWT-implementation for RIA toolkits like GWT, Flex, ... . Tom DaBlick schrieb: GWT gets translated to Javascript. Now, you might argue So? I heard Swing is pure Java. Why can't SWING by translated by the compiler to JS? The answer is because while Swing is pure Java, it is layered on top of AWT which is anything BUT pure Java. Thinking SWT? Don't go there. Like Swing it also uses native methods (real native methods (calls to C code), not JSNI) too. Where Swing and SWT ultimately make calls to native heavyweight platform specific components, GWT makes calls to the browsers dom handling interfaces via Javascript. db On Jan 10, 2:31 pm, mikedshaf...@gmail.com mikedshaf...@gmail.com wrote: OK, one of the things that you have to wrap your head around is how GWT works. You write GWT using Java, but then the GWT compiler converts this into Javascript HTML. It can only do this to Java that it specifically knows about. Your Swing JLabel component is not something GWT understands and therefore it can't compile it out into Javascript. The strength of GWT is that you develop in Java, but if your code is going to be run in the browser, it has to be Java that is compatible with the GWT Compiler. Hope this helps.
