Remote database connection problem using hibernate

I am trying to connect to a remote database (hosted on Netfirms www.netfirms.ca if anyone is interested) using hibernate. My mapping file looks like this:

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://mysql.netfirms.ca:3306/d60549476</property>
        <property name="hibernate.connection.username">u70612250</property>
        <property name="hibernate.connection.password">******</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

        <!-- Use the C3P0 connection pool provider -->
        <property name="hibernate.c3p0.min_size">5</property>
        <property name="hibernate.c3p0.max_size">20</property>
        <property name="hibernate.c3p0.timeout">300</property>
        <property name="hibernate.c3p0.max_statements">50</property>
        <property name="hibernate.c3p0.idle_test_period">3000</property>

        <property name="show_sql">true</property>
        <property name="format_sql">true</property>

        <!-- List of XML mapping files -->
        <mapping resource="customer.hbm.xml"/>
        <mapping resource="customerSummary.hbm.xml"/>
        <mapping resource="charity.hbm.xml"/>
        <mapping resource="charitySummary.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

      

        
        
        
      

    

When I run my application, I get the following printout:

    16 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found
    ....
    94 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: /hibernate.cfg.xml

** BEGIN NESTED EXCEPTION **

java.net.NoRouteToHostException
MESSAGE: No route to host: connect

STACKTRACE:

java.net.NoRouteToHostException: No route to host: connect
    at java.net.PlainSocketImpl.socketConnect(Native Method)
    at java.net.PlainSocketImpl.doConnect(Unknown Source)

      

        
        
        
      

    

I have ensured that my database is configured for remote access. I'm wondering what the reason is. Obviously, I cannot establish a connection to the host, but I'm not sure why. Assuming the hostname, username and password are correct, am I missing something?

Appendix: I tried to connect using the same driver using Squirrel and got the same exact error.
