Following is the xml that should be used if you want to use c3P0.
<cloud:data-source id="c3p0DataSource" service-name="mysql"/>
<cloud:properties id="cloudProperties"/>
<context:property-placeholder properties-ref="cloudProperties"/>
<bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://${cloud.services.mysql.connection.hostname}:${cloud.services.mysql.connection.port}/${cloud.services.mysql.connection.name}" />
<property name="user" value="${cloud.services.mysql.connection.username}" />
<property name="password" value="${cloud.services.mysql.connection.password}" />
<property name="minPoolSize" value="2" />

I didnt use variable {cloud.services.mysql.connection.jdbcUrl} which was causing the DB connection to fail. If you observe the env.log file the value for this entry also contains username and password instead of just hostname, portname and db name.
Also the property cloud.services.mysql.connection.hostname I have seen mentioned as (cloud.services.mysql.connection.name) that was also causing the issue. I guess that's not a big deal as it depends on which data source you use. In some cases it could be name and in some cases it could be hostname.
Also the highlighted code was missing entries from my xml. I would be trying now with profile feature and would update the thread based on what I see.
