Error: Invalid package registered for this action. Link on Approval Page

Hi ,

I have added a link on approval page in PeopleSoft Campus Solution 9.2 , PeopleTools 8.58 , using delivered work record "EOAW_EOPCPB0_WK. EOPCOBJ_LINK_L0 ".

As soon as i click on link on approval page it gives me error

"Invalid application package registered for this action. App Package I_ABSN_WAR_APPROVAL_HANDLER:I_CHECK_HISTORY.Contact your system administrator"

See the following application class that I am using.

import EOPC_RUNTIME:pcButtonAction;

class I_CHECK_HISTORY extends EOPC_RUNTIME:pcButtonAction

  method I_CHECK_HISTORY();

  method PC_DEFR_ViewAttachment(&pIn As array of any)

end-class;

method I_CHECK_HISTORY

  %Super = create EOPC_RUNTIME:pcButtonAction();
