OpenShift trying to connect with mySql

Question

I am trying connect to external mySql database. I get this error message on console:

Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'adminbnnSIES'@'localhost' (using password: YES))

Caused by: org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection

This is how my applicationContext.xml looks like:

    <?xml version="1.0" encoding="UTF-8"?>

</beans>

I couldnt find answer for my answer anywhere. In my pom.xml i have this dependency:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.31</version>
</dependency>

On local connection I dont have such problem, here is my local bean setup:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/test" />
    <property name="username" value="root" />
    <property name="password" value="" />
</bean>

I think the problem should be with the host you are specifying there, "localhost" doesn't seem right for an external database.
