Hi,
As the title states is there anyone who can give some info on which is the best JAVA API/CLASS for FTP interaction with Z/OS from a JCN node within a message broker flow? The broker will be windows/aix based.
I am aware of the file nodes input and output etc... This is a very specific task we want to achieve which is simply when a trigger is received in a message flow, log onto a z/os MF box and remotely FTP a file back to the broker within the same flow. We do not want the flow polling on a timed period basis only to perform a single read when the trigger is received hence why we are not using the fileInput node.
so.. TRIGGER INPUT > JCN NODE(FTP GET) > OUTPUT ...
I am amazed the new FileRead node does not offer this...
I have tried some variations of class in a JCN with limited success such as
URL
FTP Client
SUN TELNET CLASS etc
I am getting niggly errors with each way. Has anyone done this before?
Any constructive comments appreciated!  |

Why not use the trigger message to start a flow with a FileInput node on the front which does the ftp? This would prevent polling.
I'll leave others more qualified to advise on your actual question.

Hi Vitor,
We have thought of this and it is a consideration however I am not a fan of having administration commands in message flows etc... Never have been.
But it could be a last resort but hopefully not necessary. I've just downloaded apache commons net which has good ftp and I will try this and see if it is any better.
I am hoping some java folk will bite at this because whilst I have done JCN etc I haven't done FTP before and I want to ensure a robust node and FTP method...
Thanks for your reply. |

I hope you mean "use the trigger message to call a CMP API application that starts a message flow". Otherwise, you've said something that doesn't work.
I would upgrade to 7.0.0.2 and use the FileGet node, myself. |

Ok, not having the best day in terms of communication. Or anything else.

It's a valid point and a valid position.

I'm sure one will be along in a minute. Place is full of them....

We are on 7.0.0.2, do you mean the FileRead node? See above comment regarding that... |

Hrm.
I guess I did mean the FileRead node - my fingers always want to type it out as FileGet.
And I'm just as surprised that it doesn't do FTP... I had thought it did.
I guess it's not just Vitor's day for not having a good day. |

My day hasn't been much better with this issue... Maybe someone from the labs can update why no remote file read etc.. it does seem odd.. |

The basic java FTP classes should be fine.
Presumably the lack of remote file support in FileRead is a matter of development timing, rather than long term intent.
Of course, only the lab knows that for sure, and they're not allowed to say. |
