Hold Release Cancel ACTIVE JOB

[Sandeep Sakhawalkar <Sandeep.Sakhawalkar@xxxxxxxxxxxxxxxxx>]

I want to know if  jobs in ACTIVE  STATUS can be held / released / cancelled
?
Below is a brief outline of what I want to do-

AS400 sys = new AS400 ("mySystem", "myUserName", "mypassword");
CommandCall cmd = new CommandCall(sys);
If (cmd.run("mycommand") == true)
{
  Job myjob = cmd.getServerJob();
  ...
  ... 
  if (jobstatus.getStatus() == JOB_STATUS_ACTIVE) 
  {
         HOLD THE JOB
         ...
         ...
        RELEASE THE JOB
}

}
sys.disconnectService();

I came across methods in Job class where spoolfiles can be held / released.

Any workaround, suggestions is highly appreciated.

Thanks
Sandeep
