Reboot OJB

[Andre_LAU <an...@lau.eti.br>]

Hello,
I'm to test performance of OJB - MySQL using an object-oriented aplication
based on the OO7 Benchmark specification.

To run the test I'm using the JMeter tool. Well, when I run the test at the
firt time it execute perfectly ... but, when I try another run without
close/reopen the JMeter tool the execution fails. I tried to find the error,
but I can't. My execution process clean-up the database and create e
populate a new database, after some process are made to the database
(queries, inserts and updates).
Below is my last log generated by two consecutive executions (without
close/reopen JMeter):

IS CLEANED)

Note that the boot log from OJB appears only at the begin of the first run.
I tried too many things to solve this problem, like recreate the odmg
instance, force reopen database, etc, but no one worked. I think that the
problem is out of my implementation. I want to try (if possible) force
reboot of OJB or another sugestion, some one can help-me?

Below there is my main application class:
