Answer 1

The problem in your Action class MeetingRecordAction, method updateAttendeesRecord is private, it should be public

public String updateAttendeesRecord() {
    meetingRecordService.updateAttendeesRecord(attendeesListMethod(), meeting_record);
    setMyMsg("Update Successful!");
        return SUCCESS;
}

In the action configuration you should not override the default configuration from json-default package just extend it and all. Also json-default extend a struts-default, so multiple inheritance is not required.

<package name="default" extends="json-default">
  <action name="meeting_record_form" class="com.task.action.MeetingRecordAction" method="updateAttendeesRecord">
    <result name="success" type="json" />
  </action>
</package>
