RE : OJB and RMI

[Jean-Baptiste BRIAUD]

A thread problem ?
Does your problem occurs the first call or only next one ?

 Hello all:
 
 I am having running into a problem. I have an RMI server which intends to
 make calls to MySQL, using PersistencBroker. It fails when I call:
 
 
 PersistenceBroker pbroker =
 PersistenceBrokerFactory.defaultPersistenceBroker();
 
 
 with:
 -
 [BOOT] ERROR: Creation of PersistenceBrokerFactory (PBF) instance failed,
 can't get PBF class object
 ---
 
 If I remove RMI from the equation, everything works fine, i.e. the
 PersistenceBroker calls succeed.  With RMI, the Remote Server gets a
 NoClassDefFoundError For the PersistenceBrokerFactory.
 
 Is there possibly anything in the OJB configuration that might affect this
 environment?  Has anyone else been able to get OJB to work in this
 scenario?
 
 Thanks,
 Brad

Prefetch dynamic change

[Jean-Baptiste BRIAUD]

Hello,

Is it possible to dynamicly change value of auto-XXX 
(auto-delete, auto-retrieve, ...) specified in the repository-user.xml ?

By dynamicly I mean in Java code. Say in the xml file there is the
default version, but in Java code I'd like to change value for one shot.
Note that I don't want to modify the xml file.

is org.apache.ojb.broker.metadata a way to a solution ?

I was able by this way to obtain value store in the repository xml file,
but is it possible to change values (any values ?) without writing to
the file ?

   Thanks !

RE : ojb v0.9.9 problem

[Jean-Baptiste BRIAUD]

You have to use the JDC-ALIAS attribute in the database declaration of
the repository.xml.
In the code use it instead of the repository xml file name in the API.
This seem to be a change since 0.9.9.

   Hope this help.

  Sounds like repository.xml isn't in your classpath.
