My repository.xml is
<jdbc-connection-descriptor
platform="MySQL"
jdbc-level="2.0"
driver=" org.gjt.mm.mysql.Driver"
protocol="jdbc"
dbalias="//localhost:3306/ojb"
username="root"
password="root"
/>
and the OJB.properties is in the folder enhanced which is in the
classpath.
Here is a detailed output when i run my application
Using the following
classpath:./libs/commons-collections-2.0.jar:./libs/commons-pool.jar:./libs/dbsupport_mysql.jar:./libs/jakarta-ojb-0.9.5.jar:./libs/jakarta-ojb-0.9.6.jar:./libs/jdo.jar:./libs/jdori.jar:./libs/jta.jar:./libs/mm.mysql-2.0.12-bin.jar:enhanced

Also make sure the OJB.properties and the xml files are on the
classpath as
well as the MySQL Driver.
