[appengine-java] Re: GWT+servlet - how to redirect to a different page
Why don't you simply build the form panel with the specified target in
the constructor?
http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/client/ui/FormPanel.html#FormPanel%28java.lang.String%29
FormPanel uses a hidden IFrame to manage the cycle of submit/receive
response; if you give a target to the constructor it will follow
standard behavior of replacing the current page after submit.

[appengine-java] Persisting an empty set
I am trying to persist an empty HashSet in App Engine. It persists fine but when I pull the the item that contains the HashSet from the data-store the HashSet is now null. What can I do to force App Engine to store an empty HashSet? Or, do I just need to check for null and create the HashSet each time until it has something in it? I'm guessing I would create a field hashSetEmpty and not create the HashSet till I ran code that added to the HashSet. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi, Yes: why don't you only work with JDO and use its persistence manager to store your entities? The pm of jdo will handle translation between annotated pojos and datastore transparently for you and then drastically reduce your code size.

When I add elements to the collection and want to persist,
sometimes persist and sometimes not persist in the
datastore(Restarting the server of the application). The code of
example:
public void agregarEquipoConTorneo(Torneo unTorneo, Equipo unEquipo)
{
/*add Equipo with a existing Torneo in the
datastore, the unTorneo(param) class obtain with:
Torneo b =
pm.getObjectById(model.Torneo.class, idTorneo);*/
Transaction tx = pm.currentTransaction();
try {
tx.begin();
unTorneo.agregarEquipo(unEquipo);
//add unEquipo to collection equipos
pm.makePersistentAll(unTorneo);
tx.commit();
System.out.println(persistioTorneoConEquipo);
} finally {
pm.close();
if (tx.isActive()) {
tx.rollback();
}
}
Does it design someone of what this one happening?
Thanks!

Hi MG, Sharded counters help solve the concurrent write contention for an entity. Time (to the accuracy of milliseconds) helps to provide a one way arrow towards a unique value.

[appengine-java] Re: persistent and scalable global atomic counter: not possible with GAE?
Ikai, you are right - I don't need a counter, a sequence of unique and growing numbers will do.

Re: [appengine-java] Re: Instant messenger
Have you worked on XMPP or instant messenger before ? No, I haven't had the opportunity yet to work with the IM libraries although they do seem to be straight forward. Do i need any other tool other than eclipse,GWT fro development ? Besides using nearly every kind of browser (with the gwt dev addon), you can get away with just using eclipse with the google plug-in to do everything. There are a bunch of tools and best practices out there that will make your life easier in the long run. The links below are for Windows specific utils since I'm mostly working on Windows for local and Linux for remote. * Definitely use a version control system - I recommend SVN, There are others that are as good. http://tortoisesvn.tigris.org/ (windows shell svn extensions) http://subversion.tigris.org/ * While many people are drawn to using JDO or JPA for the persistent data layers - both have a tough learning curve. I recommend using Objectify to hide much of the complexities in using Big Table's no-sql nature. http://code.google.com/p/objectify-appengine/ * As you advance, you will want to use Google Guice GIN to simplify document the dependencies http://code.google.com/p/google-guice/ * A local proxy service brings daylight to the way the components communicate on the network. http://www.fiddler2.com/fiddler2/ * Firefox add-ons that are invaluable Firebug! - allows you to view the GWT client logs in the browser window instead of viewing them in the eclipse dev console (also works w/ production instances) Scrapbook Plus - for literally snapshotting the current page state with live html/image/js Web Developer - for inspecting the page contents and layout View Cookies - for inspecting/editing cookies * The MVP pattern is a great way to design a medium to highly complex application's architecture. * Take the time to look at the Session Videos from the last two years of Google IO. They will change your life - they did mine. http://www.google.com/events/io/2010/sessions.html I've got an GAE/GWT application deployed that was developed using all of the above technologies.

[appengine-java] google eclipse plugin开发gae，wa r目录不能同步
参照http://googlewebtoolkit.blogspot.com/2010/08/how-to-use-google- plugin-for-eclipse.html的官方博客。将一个maven工程改成eclipse热部署。 现在的状态是启动都是ok的，工作目录是：src/main/webapp，启动的目录是：target/your-project-name，访问正 常。 问题是工作目录的文件修改时不能同步到启动目录中去。 例如我在工作目录下修改一个jsp文件，用浏览器访问不能生效，因为启动目录里面文件还没有改变。 那位碰到过这个问题的，指教下。 -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I recommend using Objectify to hide much of the complexities in using Big Table's no-sql nature.http://code.google.com/p/objectify-appengine/ * As you advance, you will want to use Google Guice GIN to simplify document the dependencieshttp://code.google.com/p/google-guice/ * A local proxy service brings daylight to the way the components communicate on the network.http://www.fiddler2.com/fiddler2/ * Firefox add-ons that are invaluable Firebug! - allows you to view the GWT client logs in the browser window instead of viewing them in the eclipse dev console (also works w/ production instances) Scrapbook Plus - for literally snapshotting the current page state with live html/image/js Web Developer - for inspecting the page contents and layout View Cookies - for inspecting/editing cookies * The MVP pattern is a great way to design a medium to highly complex application's architecture. * Take the time to look at the Session Videos from the last two years of Google IO.

sometimes persist and sometimes not persist in the

example:

{
/*add Equipo with a existing Torneo in the

Transaction tx = pm.currentTransaction();
try {
tx.begin();
unTorneo.agregarEquipo(unEquipo);
//add unEquipo to collection equipos
pm.makePersistentAll(unTorneo);
tx.commit();
System.out.println(persistioTorneoConEquipo);
} finally {
pm.close();
if (tx.isActive()) {
tx.rollback();
}
}

Re: [google-appengine] Update an Existing object in the datastore - Problem
Objects are re-persisted if there are any fields that are marked dirty.
Sometimes, when you add objects to a collection property, since the property
reference may not be marked dirty, it will not be repersisted when the
PersistenceManager is closed. You can either:
1. Call JDOHelper.makeDirty(entity, field) to mark the field as dirty
2. Create a new, equivalent collection and point the equipos reference to it
3. (98% sure this works) Change a value in another property, causing the
entire Entity to be persisted (App Engine entities are persisted whole, not
piecemeal as you might do in a relational database)

[google-appengine] Re: must i install Visual Studio for python ssl module?
I once asked and received a compiled copy. But I have to confess I haven't tried it. There is always a risk that someone could have added in some vulnerability to a pre-compiled copy. Google used to distribute a compiled copy at this link: http://web-feature-labs.googlecode.com/files/ssl-py2.5-win32-1.15.exe however, they stopped for some reason. I wish they would put a known- clean copy back up. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] GQL Bad argument error
Hi Rahul, 1) Restructure your model so that you can query using only equality filters and the order. 2) If your data allows it, don't filter based on property_x in the query, do it in your code. You might need to fetch 10 entities, and possibly even re-fetch once or twice, but that will probably still use fewer resources than always running multiple queries -- which is what your current solution does. 3) Or if these are root entities, set the key_name to property_y and don't use order for the query, the entities will be ordered by key. If possible, I would probably go with the first or second option. You'll have to decide based on which fits your data better.
