Thanks, that makes sense.
I replaced the jar file to be 1.0.2 and it now loads fine. Now I get the
following problem when
I launch related to the repository_database.xml
Once again I took the defaults from the apache website and attempted to
customize them. The exact warning from OJB is:
[DEFAULT] WARN: [PlatformFactory] problems with platform
org.apache.ojb.broker.platforms.PlatformMysqlImpl:
org.apache.ojb.broker.platforms.PlatformMysqlImpl
[DEFAULT] WARN: [PlatformFactory] OJB will use PlatformDefaultImpl
instead
I modified the default file so that it looks like the following:
<jdbc-connection-descriptor
jcd-alias="default"
default-connection="true"
platform="mysql"
jdbc-level="2.0"
driver="com.mysql.jdbc.Driver"
protocol="jdbc"
subprotocol="mysql"
dbalias="tsi"
username="guest"
password="guest"
batch-mode="false"
useAutoCommit="1"
ignoreAutoCommitExceptions="false"
>
Are any of these settings incorrect? What exactly is wrong with the
mysql platform class?
Cheers,
Philip.

Hi Philip,
seems you mixed OJB 1.0.1 with 1.0.2 OJB.properties file. The website
always based on the latest release.
regards,
Armin
