Hi Christophe and Lucy,
I add your guide with minor modifications to OJB deployment doc.
Could you please review the doc?
Find it on CVS
http://cvs.apache.org/viewcvs.cgi/db-ojb/xdocs/deployment.xml
regards,
Armin

how

guide

>
> 1. Add the OJB jar files and depedencies into the Weblogic classpath.
> 2. Compile the following classes (see at the end of this mail) and add
> them to the weblogic classpath.
> 3. Register via the weblogic console the startup class (OjbPbStartup).
> The JNDI name and the OJB.properties file path can be specified as
> parameters in this startup class (see the code).
> 4. As usual create the connection pool and the datasource.
> 5. Check the following entries in the OJB.properties :
>
>
ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFacto
ryManagedImpl
> OJBTxManagerClass=org.apache.ojb.odmg.JTATxManager
>
>
JTATransactionManagerClass=org.apache.ojb.otm.transaction.factory.Weblog
icTransactionManagerFactory
>
> 6. Modify the connection information in the repository.xml (specify
the
> datasource name):
>
> <jdbc-connection-descriptor
> jcd-alias="default"
> default-connection="true"
> platform="Hsqldb"
> jdbc-level="2.0"
> jndi-datasource-name="datasource_demodb"
> eager-release="false"
> batch-mode="false"
> useAutoCommit="0"
> ignoreAutoCommitExceptions="false"
> >
> <sequence-manager
>
className="org.apache.ojb.broker.util.sequence.SequenceManagerNextValImp
l">
> <attribute attribute-name="grabSize"
attribute-value="20"/>
> </sequence-manager>
>
> </jdbc-connection-descriptor>
>
> 7. Write a session bean similar to thoses provided for the JBOSS
samples.

EJB
