Hi,
I'm currently trying to improve my app performances and I therefore tried to
set the batch-mode property in the repository to "true". Unfortunately,
whenever OJB attempts to submit the batch, I get the following exception:
java.lang.IllegalArgumentException: object is not an instance of declaring

I am using Oracle 8i and OJB 1.0rc4.
Here is an excerpt from my repository:
<jdbc-connection-descriptor
default-connection="true"
jcd-alias="bod"
platform="oracle"
jdbc-level="2.0"
driver="oracle.jdbc.driver.OracleDriver"
protocol="jdbc"
subprotocol="oracle:thin"
dbalias="@superbug:1521:dbmaster"
username="SEJ"
password="SEJ"
batch-mode="true"
>
<connection-pool
maxActive="15"
whenExhaustedAction="0"
testOnBorrow="false"
testOnReturn="false"
validationQuery="select count(*) from OJB_HL_SEQ"
/>
<sequence-manager
className="org.apache.ojb.broker.util.sequence.SequenceManagerInMemoryImpl">
<attribute attribute-name="autoNaming"
attribute-value="true"/>
</sequence-manager>
</jdbc-connection-descriptor>
Here is a code excerpt:
broker.beginTransaction();
broker.serviceConnectionManager().setBatchMode(true);
broker.store(o);
broker.commitTransaction();
My question: can I use batch-mode with Oracle, and if so, do I use the right
driver...
Thanks in advance.
