Controlling number of Threads for ManagedExecutorServices / Java EE 7

In Java SE one can use constructs like 

ExecutorService es1 = Executors.newSingleThreadExecutor();
ExecutorService es2 = Executors.newFixedThreadPool(10);

to control the number of threads available to the executor service. In Java EE 7 it's possible to inject executor services: 

@Resource 
private ManagedExecutorService mes;

But how can I control the number of threads available to the managed executor service ? For example, in the application I'm writing, there is an executor service that has to be executed in a single thread. So I can't just let the platform choose its preferred number of threads.

Actually, this setting should be set in the server settings, through admin console (in GlassFish for example), or during the creation of the service:

asadmin create-managed-executor-service --corepoolsize=10 --maximumpoolsize=20 concurrent/mes
