Hibernate multi-tenancy create schema during runtime

I am setting up multi-tenant support for a java web application using hibernate 4 and spring 4. The default schema is created and set when the application starts. This schema works fine when not trying to support multi-tenancy.

What I need to do now is to create a schema for each new tenant that creates an account. This schema can simply be a copy of the common schema because it will adhere to the same format.

How can I create new schemas that follow the same format as the default schema during runtime? It appears that the default schema is created when the LocalSessionFactoryBean is instantiated since that is where I specify the mapping resources.
