BPM for multiple accounts sender..

Question

We have a scenario where we get a list of accounts from  a sender file. THese accounts(will act as logins) will be used to retrieve files from their respective Unix directories.   I was thinking if BPM is the only option here. To read account from the sender file and create a connection to the unix folder and send all the files to the receiver folder. Then it goes into a loop and picks up the next account from the  sender file.
Any better way of designing  such an interface without BPN or is BPM the only option??

Hi Teresa,
there are alternatives.
Let's say for instance you have 4 files in your source folder:
logins.txt
file1.xml
file2.xml
file3.xml
where logins.txt has 3 lines with login information for 3 different systems.
You could build a 1:n multimapping where the sender file adapter reads the logins.txt file and the xml files as additional files (they'll appear as multimapping). Then, if you have PI 7.1+, you could use the new Mapping API and read the attachments in mapping runtime, ultimately generating multiple (in this case, 3) instances of the target message.
The only issue would be with dynamic configuration for the file receiver adapter, since you can't use dynamic config in multi mappings. You could easily solve that by building a simple adapter module that fills the file adapter dynamic config based on some data in the message (e.g. in the mapping you add the login data as part of the payload - if necessary, you could remove that data from the payload in the module).
Oh, and you might need enhanced receiver determination for determining the receiver systems based on the payload (i.e. logins).
Best regards,
