In some scenarios the database may not be directly accessible. But is available via a hop server.

To use this piece of code following needs to be done

• Configure database password in jvm. Property name should be dbPassword
• Configure ssh host password in jvm. Property name should be sshHostPassword
• Configure database instance to use by defining jvm property dbInstanceName equal to the object name with the configuration. Example -DdbInstanceName=DatabaseInstanceOne
• Configure database properties as case objects in com.charandeepmatta.dbtunnel.
• Define ssh server config in com.charandeepmatta.dbtunnel.SshConnectionConfig.
