Exhibit 31.2

I, Cheryl L. Whalen, certify, that:

1.       I have reviewed this  quarterly  report on Form 10-QSB of  Jacksonville
         Bancorp, Inc. and Subsidiary;

2.       Based  on my  knowledge,  this  report  does  not  contain  any  untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances  under which
         such  statements  were made, not misleading  with respect to the period
         covered by this report;

3.       Based on my knowledge,  the financial  statements,  and other financial
         information  included in this  report,  fairly  present in all material
         respects the financial condition,  results of operations and cash flows
         of issuer as of, and for, the periods presented in this report;

4.       The  small  business  issuer's  other  certifying  officer  and  I  are
         responsible for  establishing and maintaining  disclosure  controls and
         procedures  (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e))
         and internal  control over financial  reporting (as defined in Exchange
         Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer and we
         have:

         (a)      Designed such disclosure  controls and  procedures,  or caused
                  such  disclosure  controls and procedures to be designed under
                  our supervision,  to ensure that material information relating
                  to the  small  business  issuer,  including  its  consolidated
                  subsidiaries,  is made  known  to us by  others  within  those
                  entities,  particularly during the period in which this report
                  is being prepared;

         (b)      Designed such internal  control over financial  reporting,  or
                  caused such internal  control over  financial  reporting to be
                  designed  under  our   supervision,   to  provide   reasonable
                  assurance regarding the reliability of financial reporting and
                  the preparation of financial  statements for external purposes
                  in accordance with generally accepted accounting principles;

         (c)      Evaluated the  effectiveness  of the small  business  issuer's
                  disclosure  controls  and  procedures  and  presented  in this
                  report  our  conclusions   about  the   effectiveness  of  the
                  disclosure  controls  and  procedures,  as of  the  end of the
                  period covered by this report based on such evaluation; and

         (d)      Disclosed  in this  report  any  change in the small  business
                  issuer's  internal  control  over  financial   reporting  that
                  occurred during the small business issuer's most recent fiscal
                  quarter (the small business  issuer's fourth fiscal quarter in
                  the case of an annual report) that has materially affected, or
                  reasonably  likely to materially  affect,  the small  business
                  issuer's internal control over financial reporting; and

5.       The  small  business  issuer's  other  certifying  officer  and I  have
         disclosed, based on our most recent evaluation of internal control over
         financial  reporting,  to the small business  issuer's auditors and the
         audit committee of the small business issuer's board of directors:

         (a)      All significant  deficiencies  and material  weaknesses in the
                  design  or  operation  of  internal   control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  small business issuer's ability to record, process,  summarize
                  and report financial information; and

         (b)      Any fraud,  whether or not material,  that involves management
                  or other  employees who have a  significant  role in the small
                  business issuer's internal control over financial reporting.
