Question regarding supported features

[zharpaz-bmc-com]

Hi,
We consider to use as2-lib and I have a few questions:

1. What AS2 version does the library supports (1.1, 1.2)?
2. Does is supports any of the AS2 profiles (http://www.filetransferglossary.com/as2-optional-profiles)?
3. Was it tested by the Drummond Group certification tests?
   Thank you for your help,
   Ziv Harpaz, BMC.

Hi,

ad 1) Currently AS2 1.1 is supported.
ad 2) I have never formally investigated it, but here's what I found out:

• FileName preservation (FN-MA) is possible, through customizing (sendfilename="true")
• Chunked Transfer Encoding (CTE) is supported

ad 3) No.

Hi Philip,

Thank you for the fast answer! as2-lib looks really good.

1. How do I set CTE when sending a message?
2. When sending big files, do all the file needs to be stored in memory?

Thank you for your help,
Ziv

Hi Ziv,
when sending a message use AS2ClientRequest.setContentTransferEncoding (EContentTransferEncoding).
See https://github.com/phax/as2-lib/blob/master/as2-lib/src/test/java/com/helger/as2lib/supplementary/main/MainSendToMendelsonTest.java for an example on how to invoke the client.

Concerning big files: I must admit I never really tested it. What is "big" for you?

Hi Philip,

I am asking about Chunked Transfer Encoding. (not Content).

Regarding file size, big would be above 50GB. My question is whether the package loads the whole file to memory.

Thanks,
Ziv

Mea culpa - too many abbreviations.

• Chunked encoding is currently not supported, but easy to add, as it is part of the default Java HttpUrlConnection as well as part of Apache Http Client
• The big files will most likely cause an error atm. I never really tested with large files, but I think I should to. Any PR in that direction is appreciated.

Happy weekend,
Philip

Thanks a bunch Philip. We are now in the phase of choosing the library, and as2-lib is a serious candidate. We will seriously consider a PR when we get there.
