Hello folks,
I am stucked in a problem using OJB.
I am trying to use MySQL and OJB but it always happens an error during
broker.beginTransaction() that says "Can't lookup a connection".
Anyone has a sugestion to solve it???
Could you please post the whole stack trace - I can't find the root
exception?
In your jdbc-connection-descriptor you set:
> dbms=MySQL
please try to replace this by
platform="MySQL"
For example the my local mapping for mysql look like this:
<jdbc-connection-descriptor
jcd-alias="default"
default-connection="true"
platform="MySQL"
jdbc-level="2.0"
driver="org.gjt.mm.mysql.Driver"
protocol="jdbc"
subprotocol="mysql"
dbalias="//localhost:3306/ojb"
username="root"
password=""
batch-mode="false"
useAutoCommit="2"
ignoreAutoCommitExceptions="false"

regards,
Armin
Thanks in advance, Marcel.
