Derby and commons dbcp compatibility

hi ...
I am new to using derby .. i have some doubts on it ... please clarify...

1). can i use embeddedDriver of derby with commons pool and dbcp

2) Can i use the con from the pool (created with embeddedDriver and pools) to be accessed by multiple users to make insert,delete operations

3) Do i have to shutdown the database for every user ... if every user has one connection each...

4) can i create a read/write database to be accessed by multiple users in derby using embeddeddriver.

thanks in advance
