[rules-users] How to use Drools Flow?

[XiaoMiTang]

Hi, Sony John:
My English is not good,so i can not explain well.
According to the previous mails,you can understand my confusion point.
If a work flow requires more than one person to finish it,like this:
(1)user A ask for a day's leave;
(2)user B approval it;
(3) An E-mail send to user A;
you can creat a *.rf file like this:

Start--->Action1--->Human Task--->Email--->End

In Action1,you can new an application form and add it to the DB using Java
code(this is your business logic,not Drools Flow's)

user A log in the system,run the code:
session.startProcess("……");
the work flow starts,an application form will be created and added to
DB,then,the flow reach the Human Task node, a task will be created and added
to DB.
user A log out.

user B log in.
user B claim and complete the task using Drools Flow's API:
client.claim(task.getId()…………）
//here,do something to approve the application form(your business logic),eg.
change the application form's
// state from 'wait' to 'approved' in DB or something else.
client.complete(task.getId()…………);
then,the work flow will go on,the email will be send automatically……

I just learned Drools a few days,can not guarantee that my understanding is
correct.
