Hello all,
I am getting this error when I am doing a broker.getCollectionByQuery() very
intermittently. The same piece of code works some times and fails some times
with this error:
[5/11/06 10:02:15:498 EDT] 24df24df SystemErr R java.lang.NullPointerException

Hi Vamsi,
could post more details of the used OJB version and how you are using
OJB? Could it be a concurrency issue, is it guaranteed that each thread
use it's own PB instance?
regards,
Armin

Hi Armin,
autoCommit set to 1 does not avoid freeze. The fact is that database is only
used to be read, so rollbacks ( by disconnecting) will never be long.
autocommit is however set to 1 now. Thanks for the advice.
I dont' known why it freezes when maxIdle set to -1 and why it does not when
Hi Armin,
I am using OJB1.0.1 on WSAD 5.1 using JDK1.3.1. I have a simple table of the
form:

CREATION_DATEDATE
And my query code is like this:

Hello all,
I am almost there with regards to asynq data merging based upon GUID. What i
am looking for now is a way to have a creationdate field in
indirectiontables. I am not sure how to do this since it is all handled by
OJB.
The case is like this, a local server has records that are not

Hi Armin,
My broker factory is:
PersistenceBrokerFactoryClass=org.apache.ojb.broker.core.PersistenceBrokerFactorySyncImpl
Connection factory class is:
ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl
Persistence broker pool settings are:
when MaxIdle is set to 0, it works well, and the 5 maxActive are sufficient.
No freeze at all.
The whenExhaustedAction block is well what i want, no error. And it works
with maxIdle set to 0.
I don't see why no connection remaining in the pool leads to a
serialization. Dead lock is a good

it's a moot point whether only one connection or five connections are
used when maxIdle is 0. I think that maxIdle=0 will immediately close
returned connections.

No idea. All is ok on paper!

Yep, i 'm affraid that _pool.size() is always than -1 !! (the maxIdle), so
shouldDestroy is true, and no pool is added.
May be it's me . Someone can confirm this ?

throws Exception {
boolean success = true;
Oops, it's me.
Sorry

Yep! The pool is always empty.
I would recommend first to try the connection-pool default settings
