Declare and initialize a varray of collection Object and pass it as OUT Par

Question

Hi ,
How to declare and initialize a varray of collection Object and pass it as OUT Parameter to a procedure.
Following is the Object and VARRAY Type 's I have created and trying to pass the EmployeeList varray type variable as an OUT parameter to my stored procedure, but it is not working. I tried different possibilities of declaring and initializing the varray type variable but it did not work. Any help would be appreciated.
CREATE TYPE Employee IS Object
          employeeId     Number,
          employeeName VARCHAR2(31),
          employeeType     VARCHAR2(20),
CREATE TYPE EmployeeList IS VARRAY(100) OF Employee;
/* Procedure execution block */
declare
employees EmployeeList;
begin
EXECUTE displayEmployeeDetails(100, employees);
end;
Thanks in advance,
Raghu.
