still get the same error.
I'm using the same code I sent you for the test case Max. Do you see
any tell-tale signs in here that indicate I've mis-configured

1.normally on spring, we will use @transactional at service layer for
concurency control, if we use google guice, is there similar

2. is google guice all classes supported in GAE? i about to start look
at google guice, as i find some of the classes in spring
Hi all,
I understand this is a relatively basic question, but I have been
searching around and can't find an answer that explains it. According
to http://www.datanucleus.org/products/accessplatform/jdo/types.html
there shouldn't be any problem with using an int as a PK, but when I
use it in my

different ways like by theme, category, brand, price as you can do for

Thanks Max, that fixed my problem with the inheritence.

I'm running some JUnit tests to excercise my data-layer classes using
the TestEnvironment patter implementing ApiProxy.Environment (i.e., so
I can test my code's datastore operations inside of JUnit).
The tests run fine, except when I try to interact with the Statistics

Sorry for not clarifying -- my example is all JPA, and the import
statements in my code imply the following:

@javax.persistence.Embedded

I should say that Spring 3.0.0.RC3 needs the latest version of any and all

Have you tried to lazy load your beans? In my local tests I have a very
fast startup.
Well this won't help to use id as an array index but...

Hi,
Glad to see some reasonable inheritance support in Datastore. However,
I'm a little puzzled. I am trying to setup a simple persistent class

I assume they aren't doing a full JVM startup every warm up, are they?
Seems they could load it into the JVM memory.. then page it out to

My guess is that they have some sort of soft undeploy which tells jetty to
purge the app's code and data from its memory (after some period of
inactivity). Then when a request arrives jetty re-loads the app (meaning a
full restart of the app). Each jetty might be supporting multiple apps.

The logs show that Guice is taking 5 seconds to build the Injector. I
have tried setting Guice to development mode in the hope that it would
start up faster but it takes about the same as production.
Does anyone else find Guice slow to start?
On top of this delay it is taking 7 seconds before
