How can I set the application information on a session using the Oracle thin JDBC driver?

I'd like to change the application information that is shown when inspecting Oracle 10g sessions using the Oracle Enterprise Manager application:

Application Information  
  Program    'my program'  
  Module     'something'  
  Command    UNKNOWN

I'm using the JDBC thin driver to connect, and I have to admit I'd rather not use the OCI driver if at all possible. Can I do this with the thin driver, and if so, how?

From stackoverflow

• use the appropriate method within the DBMS_APPLICATION_INFO package (.SET_ACTION, .SET_CLIENT_INFO, .SET_MODULE

  Chris R : uh... at risk of coming off as dense, what is the "DBMS_APPLICATION_INFO" package?

• DBMS_APPLICATION_INFO should take care of that:
