Serious Unmarshalling Problem

Question

I have been having a serious problem implementing an RPC web service which needs
to return
arrays of Java Beans nested three layers deep. In order to simplify the problem,
I constructed these
simple Java Beans (abbreviated here):
Class A
B[] bArray;
Class B
C[] cArray;
Class C
String value;
Then I wrote a client similar to this:
C c = new C();
c.setValue("Dave");
C[] cArray = new C[2];
cArray[0] = c;
cArray[1] = c;
B b = new B();
b.setCArray(c);
B[] bArray = new B[2];
bArray[0] = b;
bArray[1] = b;
A a = new A();
a.setBArray(b);
C c1 = service.getC(c):
B b1 = service.getB(b);
A a1 = service.getA(a);
In my web service, I have three methods:
C getC(C);
B getB(B);
A getA(A);
All these do is return the objects they are sent.
When getC is called, it works fine. In the verbose mode, you can see that the
XML sent
and received is the same. getB also works fine.
But getA does not work. The response is abbreviated and contains nulls. It appears
that
the data is not being unmarshalled/unserialized correctly on the server side.
This is a serious problem that has my project in jeopardy. Please advise,

Answer 1

please use spaces instead of tabs :
why did you convert a date, which is formatted in your DD-MON-RR - format, back to date with the format DD-MM-RR ?
try this: I reformatted it, so that you can better read it :
  CURSOR cur_first IS
  SELECT a.item_code,
         b.item_description,
         a.lot_no,
         d.name model,
         c.vendname,
         date_of_purchase,
         warrenty_upto,
         quentaty,
         rate,
         pc_type,
         decode (warrenty_flag_yn, 'W', TO_DATE (warrenty_upto,       'DD-MON-RR'),
                                   'A', TO_DATE ('31-MAR-' || v_year, 'DD-MON-RR'),
                                   'X', TO_DATE ('31-MAR-' || v_year, 'DD-MON-RR')
                ) AS amc_date
    FROM pc_item_procurement_history a,
         pc_item_master b,
         pc_vendor_master c,
         pc_model_master d
   WHERE ...and I think you have a problem in the where clause. Are you sure, that the string warrenty_upto has the format DD-MM-RR. Or has it the format DD-MON-RR ?
(TO_DATE(a.warrenty_upto,'DD-MM-RR')
