No it doesn't. Middlegen will only generate one *Bean.java for each of your
tables. You choose in your build script what you want Middlegen to generate.
Just strip away everything except cmp20.
And make sure you only have a PERSON and EMAIL table in your RDBMS.
This way Middlegen will generate only 2 files, PersonBean.java and
EmailBean.java. Promise.

(I used Middlegen to create this)
/**

public abstract java.util.Collection getEmails();

1) create a new Person (the EJB way via local home interface)
2) Create a new Email (the same way)
3) person.getEmails().add(email)
