Any example of assembling a Jacobian matrix of DMComposite object?

Hi,
I have an optimization problem in 2d with some scalar parameter, thus
DMComposite is used to manage the date structure. If I am going to
write down the Jacobian matrix for the system, I come up with
(mx*my+1,mx*my+1) matrix. Is there any example in PETSc of assembling
the Jacobian for optimization problem?
Thanks very much!
