[kepler-dev] How to add slaves in a remote workflow in Java(in Eclipse)

[Jianwu Wang]

Hi Neha,

     First of all, I haven't seen anyone working on workflow simulation 
in Eclipse before. Your work is very interesting. May I know why you 
want to do it? I guess you are not just replacing Kepler GUI with 
another GUI, right?

     The code of master-slave module is done long time ago. So my 
information on the interfaces below is just my best guess. You have to 
verify its correctness.

     1) How do I add slaves? At the construction function of 
org.kepler.distributed.MasterController class, it tries to read 
available slaves.

     2) How do I allow/deny Access? The function processUserInACL() in 
org.kepler.distributed.SlaveController class will check whether the user 
is allowed or denied.


Best wishes

Sincerely yours
