Wheeler-DeWitt Equation....

Someone could explain me how this equation is obtained?..in fact you have Einstein Lagrangian L=(-g)**1/2R where R is Ricci,s scalar then with that you would form the Einstein Hamiltonian..and quantizy moments Pr as d/dr where d/dr is the functional derivative...but i still have doubts...

a)what are the constraint imposed and why you must impose them

b)What would be the Hamilton Jacobi equation for that system if in general relativity there is no time defined?..

Could someone say where is the original Wheleer or De Witt article?..thanks.
