If you build the files as described in getting started doc (with all
steps) you can check the generated repository.xml file (separated in sub
files). The most important file is build/resources/repository_database.xml:
<jdbc-connection-descriptor
jcd-alias="default"
default-connection="true"
platform="MySQL"
jdbc-level="3.0"
driver="com.mysql.jdbc.Driver"
protocol="jdbc"
subprotocol="mysql"
dbalias="//localhost/productmanager"
username="steve"
password="secret"
eager-release="false"
batch-mode="false"
useAutoCommit="1"
ignoreAutoCommitExceptions="false"
>
...
If this file contains the wrong settings you can try correct the
settings by hand and run the app again.

Armin
