How to design a framework like schedule?

The purpose is will have main class like schedule, It will according xml definetion to do some thing.
Ex: AM 10 must use DemoSchedule class, DemoSchedule maybe to check somwthing with database, AM 11 must use Demo2Schedule class to produce some report from database, AM 12 must to send mail by another class,
How to think and design ?

The xml is base structure like that example.

<?xml version="1.0" encoding="Big5" standalone="no" ?>
<!DOCTYPE ScheduleWork SYSTEM "Schedule.dtd">
<ScheduleWork>

<Schedule>
<Classname>DemoSchedule</Classname>
<Hour>10</Hour>
<Frequency>1</Frequency>
<DBCondition></DBCondition>
<Log>LogName</Log>
</Schedule>

<Schedule>
<Classname>Demo2Schedule</Classname>
<Hour>11</Hour>
<Frequency>1</Frequency>
<DBCondition></DBCondition>
<Log>LogName</Log>
</Schedule>

<Schedule/>
</ScheduleWork>

<?xml version="1.0" encoding="Big5" ?>
<!ELEMENT ScheduleWork (Schedule*)>
<!ELEMENT Schedule (Classname, Hour+, Frequency*, DBCondition?, Log?)>

<!ELEMENT Classname (#PCDATA)>
<!ELEMENT Hour (#PCDATA)>
<!ELEMENT Frequency (#PCDATA)>
<!ELEMENT DBCondition (#PCDATA)>
<!ELEMENT Log (#PCDATA)>

Posted by: jam Posted on: 2003-04-25 18:26 I think no people are interesting about this. But I still provide my solution. the attach file is the source. The author is me. If you think this sample is not too bad, give me a point. One thing, I need to finish, what's different of Class.forname and ClassLoad example.zip (4.29k)

Thanks. I wish you like it. I need it. Schedule.xml and Schedule.dtd must at System.getProperty("user.dir") example.zip (4.27k)
