Re: GWT Designer Libraries

Re: Problems with JDO
Hi Caio,
Ensure that you do not instantiate factory more than once.
Look at
http://code.google.com/appengine/docs/java/gettingstarted/usingdatastore.html
[snip]
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory(transactions-
optional);
private PMF() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
[/snip]
And in case you've just started your application, do review objectify
at http://code.google.com/p/objectify-appengine. It's fantastic and
will ensure that you never come across issues that you've posted :)
Hope that helps!

Hello,
I'm having some troubles with JDO. I have declared two independent

two different java classes contexts. Then, the program execution
generated an exception about the duplicated name of
PersistenceManagerFactory. I have corrected the name of this object at
jdoconfig.xml but a new exception ocurred:
javax.jdo.JDOFatalUserException. In addition, if you want to see the
complete error list, read below:
Caused by: javax.jdo.JDOFatalUserException: Application code attempted
to create a PersistenceManagerFactory named transactions, but one with
this name already exists! Instances of PersistenceManagerFactory are
extremely slow to create and it is usually not necessary to create one
with a given name more than once. Instead, create a singleton and
share it throughout your code. If you really do need to create a
duplicate PersistenceManagerFactory (such as for a unittest suite),
set the appengine.orm.disable.duplicate.pmf.exception system property
to avoid this error.

Multi-Project GWT Application and NoClassDefFoundError
Hi Guys, I have a GWT+GAE application split under multiple Eclipse projects, all GWT projects. I have the structure similar to the following: - MainApp: With module entry point and server side code for GAE. - AppServices: All GWT-RPC service definitions with Async interfaces. For example, LoginService and LoginServiceAsync etc. - AppCore: Core interfaces and classes MainApp contains the implementations for the RPC interfaces (e.g.: LoginServiceImpl etc) The problem is that when I build the project, the LoginService class file is never copied to the war/WEB-INF/classes folder. So, during the build time, it's all find but during runtime it gives an error - NoClassDefFoundError. I failed to locate any solution for the same on the web. So, finally, I customized the build.xml file and have put up a small DIY documentation at http://blogs.mastergaurav.com/2010/10/28/google-app-engine-and-gwt-multi-project-application Hope you find it useful. -- Happy Hacking, Gaurav Vaish http://www.mastergaurav.com -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Event Handling - ondragstart and onselectstart
Hi Thomas, Great inputs. Couple of things: 1. Let me know if I can be of any help to your new-event-system- implementation. Would love to do that. 2. Regarding the specific events, I think they're available across browsers and OS. I am porting Dojo for GWT and found http://bugs.dojotoolkit.org/browser/dojo/trunk/dnd/Moveable.js#L49 So I assume, adding the events should be pretty strightforward. The only reason that I see these (and may be some more) events have been left off is probably because the current events take up the bits from 0x01 to 0x80. And in JavaScript, numbers are 64-bit floating points. Well, technically, if I look at -- the above should not be a constraint because looking at the specification IEEE 754-2008 (http:// en.wikipedia.org/wiki/IEEE_754-2008), it should be possible to use upto 52 digits before decimal (see also http://en.wikipedia.org/wiki/Double_precision_floating-point_format). May be, it's just a matter of time or realizing that these events also exist ;) -Gaurav www.mastergaurav.com On Oct 14, 3:02 am, Thomas Broyer t.bro...@gmail.com wrote: On 13 oct, 19:36, masterGaurav gaurav.va...@gmail.com wrote: Hi, I am implementing Drag-n-Drop functionality in GWT, for which I need to handle ondragstart and onselectstart events.

I started working on a patch earlier this summer but never finished it. If you want to contribute to such an effort rather than add new Event constants et al.

Re: GWT new App Development
Hi Mittal, Great question! For my applications, I have pure-GWT as well as pure-SmartGWT approaches. I have particularly not used the MVP pattern as is available on the website... but definitely, something like that. It is an implementation of MVP pattern. I have created a slightly different event-bus... more of a global- event publish-subcribe mechanism combined with command pattern. What goes without saying is if you want to develop a larger application, MVP pattern is there to stay. Stick to it... exact implementation of the pattern can be application based. -Gaurav www.mastergaurav.com On Oct 15, 4:15 am, Mittal mitt...@gmail.com wrote: What is the most common approach followed for new App development using GWT 1) Only GWT widgets/api 2) GWT widgets/api and MVP Pattern 3) GWT widgets/api and guit 4) Smart GWT widgets/api and (MVP or guit) I have done few sample/demo applications using GWT widgets/api and MVP pattern.

Extending GWT - Eclipse Plugin
Hi, Firstly, kudoos to the GWT team for the great effort! Secondly, I am currently working on extending GWT to create a custom library that's reusable. To be specific, I'm looking at porting Dojo on GWT (http://sf.net/ projects/dwt). The project was off-the-track for quite a long time and with breaking changes in GWT 1.6+ and more fun with 2.0, I'm more happy than sad for not working on it for such a long time :) Anyway, coming to my point - how do I compile the extended GWT library without any entry-point.

Re: Dynamic Evaluation
Hi Walden, Sorry to disappoint. I'm not sure how or why you would port that to GWT. Maybe someone else on the list can be of more help to you. If your query is as to why I would like to port Dojo for GWT, then there's a valid case for it. 1- I'm try to combine the power of GWT and Dojo. 2- I saw an initial interest in the community for this project. For instance, have a look at http://turtle.dojotoolkit.org/pipermail/dojo-interest/2008-July/032549.html 3- It opens up another option for Dojo users. Why not use Eclipse or Netbeans or any other Java IDE to develop Dojo based applications. Regarding the how of dojoAttachPoint, I think I've got a solution.
