Hi tsrisudh,
There is no need for PEA to be up to do a checkin and checkout. I dont think u r too clear about what a checkout is and how a checked out workitem can be checked in.
see, checkout is used when the activity is to be locked by any of the user to do some processing. The processing can be implemented as a program logic or it can be some manual processing like verifying a file. PEA wont come into picture for this.
PEA comes into picture when ur activity processing logic is implemented as a program registration, in which u specify the executable on various platforms and the parameters to it and stuff. The program can be made to run using the start() API, for which the PEA has to be started before or by making the activity an automatic one. Its not a good practice to use PEA for automatic activities though. we have to use an UPES instead.
Just to add up, invoking automatic activities implemented in java through PEA has been revoked in MQWF 3.6.
checkin is a process where the activity locked by the user commits it with a certain status and by modifying the output container if needed. The control then moves onto the next activity based on the exit condition set, if any. again, as u can understand, PEA wont come into picyure here.
Thanks and Regards,
Supreeth |
