The link explains the solution for cayenne 1.2.
You can try with cayenne 3.1 being aware that packages named
org.objectstyle.* have been renamed as org.apache.*

Congratulations to cayenne commiters!
DI is very handy when you have to alter ServerRuntime behaviour, we have an
application already using 3.1 with DI to implement
multitenancy (chaging postgres schema depending on authenticated user).
We are also using cayenne DI to manage other dependency inje
I'm wondering if it is possibile to specify the ServerRuntime to
ROPHessianServlet
injecting a MapLoader that 'moves' DbEntity on different database schema
depending by ClientChannel authenticated user.
Any idea?

EM
I was doing some tests on multitenancy implementations using cayenee 3.1
beta 2 and postgres , using 1 schema per tenant.
I instancend one ServerRuntime per tennant this way:
public static ServerRuntime createServerRuntime(final String
tenantSchema) {
ServerRuntime runtime = new Serve

We have a web multi tenant application developed with cayenne 3.0.
Tenants are implemented in a single database, so there's a 'tenantId' on
most of database tables.
With cayenne we implemented the tenancy, 'injecting' the property, either
on SelectQuery and new entities, using a custom automated
I suggest to use a "fresh" context for every form you gonna instance, that
will avoid leaving uncommitted objects around in one single context.
You can eventually avoid reflection , since every cayenne objects have
static string fields containing method names, that can be readen/written
using read

List toDelete=new

toDelete.addAll(_forecastItem.getForecastContendingLineItemArray());
for(ForecastContendingLineItem temp : toDelete) {
_forecastItem.removeFromForecastContending
Also try to replace
// Delete any condending ads
for(ForecastContendingLineItem temp :
_forecastItem.getForecastContendingLineItemArray())
{
_forecastItem.removeFromForecastContendingLineItemArray(temp);
}
with
List toDelete=new

toDelete.addAll(_forecastItem.getForecastCon
you should create
ForecastContendingLineItem from a contex using
context.newObject(ForecastContendingLineItem.class);

I'm trying to move an application built around cayenne 2.0.4 to

I've some objects with 1 to n

So i tested

Nice work, i did something like that in the past, but i used json
serialization, and skipped GTW, cause GTW widgets are very poor, unless you
plug Ext GW, but Ext libs are performace killers (I tried em on both IE and
Mozilla but they never run smooth as u expect). I'm hoping in javaFX, where
port
pretty
involved, however if you are doing a one-off thing, it is doable.
Also I would recommend to switch to Cayenne 3.0 at least temporarily
to confirm that the fix I described is indeed working for you. There
may be some other things at play here. Who knows.

in Cayenne 3.0 (which is now in beta):
query.setStatementFetchSize(1000);
This propagates the fetch size setting to the JDBC statement, reducing
the driver memory footprint.

Ok you didn't mention that in the original me

using it? Anyways, the best option will be to try profiling your application
to see what produces leaks.
Here's an example of getThreadObjectContext():

I'm using cayenne 2.0.4 with ROP and a swing application, and everything
working fine.
I built a framework ontop of cayenne libs for managing prefetching and
concurrent updates.
I read that incoming cayene 3.0 will enanche ROP performances.
Do you think i can try cayenne 3.0 or should be bet
concrete classes
for entities.
It's been awhile since I looked at them, so I don't know if they're
suitable for public consumption.

Hi agree with Mike, unless you have previous designed objects, i'd take

If u get previous designed objects u could work on the package 'entities'
implementing
methods do adapt DataObjects to your needs. IDEs (at least NetBeans) got
refactoring services
that can
and i will look into localObjects solution, this might lead to less concurrency

Hello Emanuele,
Thanks for your reply.

Hi Reinout,
i'm not an apache Wicket expert, but the Exception its obiusvly casted by the
fact that ur application is casting objects into different DataContexts.
What happen if u steps into
final Person auxiliary = ObjectFactory.getInstance().createPerson();
auxiliary.set
this.datacontext.commitChanges(); is correct
I fear u didn't create the object that you are populating, into datacontext.
Check ur this.getPerfil(objid), the object that you are updating must be
created into context or by a query
SelectQuery q=new SelectQuery(this.queryClass);
List data = ctx.per
a better way to detect relationships than reflection on the method
sigs - access Cayenne metadata available from EntityResolver:
EntityResolver resolver = context.getEntityResolver();
ObjEntity entity = resolver.lookupObjEntity(queryClass);
