Dynamic read file based off inbound header

Question

This is all done with BPEL
1. We want to get a file from a server VIA FTP adapter. So we setup an ftp adpter to get L11*.TXT (Any files beginning with L11)
1A.So we create this FTP adapter and then we create a receive activity to get this file from the FTP adapter.
***********Now mind you we have created our variables that come into play later such as inbound FTP adapter header & outbound FTp adapter header*************
2. Below this receive we create An assign activity with a copy operation.
Now for this assign we simply create a copy operation that includes our headers. Specifically we choose why down in the heirachy of Inbound and outbound ftp adter headers the :filename option
2A. So what we have is an assign with a copy operation from in bound ftp adapter to outbound ftp adapter
3. Then we have our fist invoke. ********Now mind you ************ BPEL cannot overwrite a file and the customer wants the file name the same as was picked up. Meaning no %seq # or %date or date stamp whatever you perfer.
So we do this first invoke and attach it to another FTP adpter that gets Sync file . Now this second ftp adpter will use the filename of the originally picked up file to go "pick up" and delete it from destination. We kinda trick the program if you will. So this ensures we dont delete a file that has a replacment behind it. Also ensures no overwriting or %seq # is needed.
On this invoke we have under adapters section Input header variable: OutboundFtpHeader (Mind you we did a copy on the first assign from inbound to outbound header varibale.)
We do nothing with any data collected between the first invoke and syncgetftpadapter. We just make it think it is going out picking up a file. And in this perspective we can choose delete after the pick up and inevitably it will "pick up file" At same time now that file is deleted on destination, thus making overwriting and %seq # not needed.
4.
We create another assign below our invoke
this has our inbound header copied to outbound once again
Specifically :filename
5.
This will lead to another invoke which leads to another ftp adapter that drops off the orginal file that was picked up now it can drop it off with that same filename as picked up and no overwriting neccassary because the file was deleted off the destination already.
Well when you make a Put ftp adapter you must specify a filname and we just want a dummy filename well we thiunk that is a dummy, because we are trying to use the orginal file name as the one to make it when it drops off whatever filename it picked up .
for example we choose test.txt thinking inbound variable will overwrite it
but the right file gets transferred but wrong file name attached.
my guess is that the putftpadapter overwrites any "filename specified" Or inbound header file name. lol you need to have a file name on the put you need one no way around it.
So i guess what im trying to do is pick up files then have the program dynamically be able to drop off that filename and contents to the destination.
Icould create three seperate programs for our three L11 files but that is alot of overhead?

Answer 1

Hmmm maybe someone can point me to a site that explains how to put catches in. I mean i know how to put them in but i want to make sure im doing this correctly. Also maybe debatching, I have heard of this but i want to understand how exactly it works and how to implment this.
Ok and one more thing ............ I have a 3 files as noted above that are suppose to move. Disregard my problem with send three and all that for a moment, Now I have stated above that we have a little trick included in this where we put a get on the source to "get" the files off the source cause for some reason it wont overwrite the file. Well on was doing some testing on my box. I got an exact replica of the files that we are doing this project for and i setup a test bpel project on my machine and deployed to our test env. Now I was deploying to our test env before also but the source server was a corporate server up in Canada. Now when i did this it overwrote the file :( so my next guess was hmmm maybe the source server FTP is not setup for our username to be able to overwrite the files???
I have a simple local FTP server and was looking at the setup, and my question is. There is an option(s) to pick for new user setups
delete
write
read
ammend
Would ammend give the right to overwrite ?
Not 100% sure the source is running the same ftp application as I am locally but it will overwrite a file
One more thing sorry lol
To try my catches out i would have to somehow make the file error in the middle os the process?
I was thinkin of that yesterday I'm like well i put the catch in but how do i know if it will truely work
