Re: Antwort: AW: performance when displaying lists

hi again,

ok, but isn't it a lot of work to create all the interfaces and proxies? you need 2 classes and one interface for every proxy implementation, or am i wrong?

If you use the OJB dynamic proxy feature you only have to write a interface for yor entity class. OJB generates the proxy class dynamically.
just set proxy="true" in repository.xml

cheers,

Hi Juergen,

we are using proxies in single mode. This works fine. We wrote our own
models for swing-components using proxies, so only the shown objects
will be materialized.
The performance is ok.

hi!
i want to display several lists (collections of the same class). the user chooses one of the objects, and this will be loaded from the database.

my current solution is a PB.getCollectionByQuery, but this is very slow, because the whole object tree is loaded (but not used). is there a solution?

i'm not sure, but i think this should be done by using proxy classes, but i had lots of troubles with them in client / server mode (never tried them in singlevm).

please help
