I think there are several problems with the cache implementations :
* ObjectCacheDefaultImpl
This cache uses soft references for storing objects,
but not for the keys so they stay in the map forever.
The key for a garbaged soft reference is only removed

I had the same problem with the default cache implementation.
There are several cache implementations proposed in ojb:
* ObjectCacheDefaultImpl
This cache uses soft references for storing objects,
but not for the keys and the objects stored so they
stay in the map forever.
I've got the following error that is thrown when rolling back a transaction.
org.apache.ojb.broker.PersistenceBrokerException: Set autoCommit(false)
failed
at
org.apache.ojb.broker.platforms.PlatformDefaultImpl.changeAutoCommitState(Pl
atformDefaultImpl.java:208)
at
org.apache.ojb
The validation query is used by ojb when it retrieve a connection
from the pool. It launches the validation query and if it fails,
the connection is discarded and it tries to borrow a new connection
from the pool.
here is a snippet of the code i use to ensure the connection to the
database is worki
I think the only way for the client to be aware of
server-side modifications to the database is to use
a distributed cache (OSCache, Swarmcache, jcs, ...).
The other way is, as Armin mentionned, not to
use cache at all on the client.
For other tools to do o/r mapping see
http://c2.com/cgi-bin/wiki
Your configuration file references log4j. You must

It also seems that cached anonymous keys are not removed from
the cache when an object is deleted from database.
Will these problems be solved, or should i try not to use

Is using a per-broker cache an option? If so you will effectively have
the cache cleared every time you obtain a new broker/close a broker.

The problem is that at some time, i've got errors when inserting

The Identity class caches internally the hash code

These attributes are not declared transient, thus
the computed hash code is serialized. The problem is
that the Class.hashCode() method not overriden

Could the m_stringRepresentation and the m_hashCode
