Chapter 8; Using MySQL but with a remote host.
I'm stepping through Chapter 8 and I have another machine with MySQL already installed on it. So, I thought, rather than installing MySQL on the same machine as my JBoss server, machineX, I'll just point the configuration to machineY.
I tried this but when I deployed the cmproster application it failed to get a connection because it was incorrectly looking for MySQL on the JBoss server.
Here is my cmproster configuration file: (jbosscmp-jdbc.xml)
<?xml version="1.0" encoding="UTF-8"?> <jbosscmp-jdbc> <defaults> <datasource>java:/MySqlDS</datasource> <datasource-mapping>mySQL</datasource-mapping> </defaults> <enterprise-beans> <entity> <ejb-name>PlayerBean</ejb-name> <cmp-field> <field-name>position</field-name> <column-name>POS</column-name> </cmp-field> </entity> </enterprise-beans> </jbosscmp-jdbc>
Here is the MySQL deployment descriptor:
<?xml version="1.0" encoding="UTF-8"?> <!-- $Id: mysql-ds.xml,v 1.3.2.1 2004/12/01 11:46:00 schrouf Exp $ --> <!-- Datasource config for MySQL using 3.0.9 available from: http://www.mysql.com/downloads/api-jdbc-stable.html --> <datasources> <local-tx-datasource> <jndi-name>MySqlDS</jndi-name> <connection-url>jdbc:mysql://machineY:3306/jboss</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>jboss</user-name> <password>password</password> </local-tx-datasource> </datasources>
Here is the error I get during deploy:
10:14:51,132 WARN [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable:

Notice this exception references machineX, that is the host JBoss is using. How come it is not pointing to machineY. My configuration files are pointing to machineY and machineY has MySQL installed on it.
Am I missing some other configuration that is required to access databases on remote machines.?
Any help will be greatly appreciated.
