|AS2 (Applicability Statement 2
protocol) helps users connect, deliver, validate and reply to data that
trading partners move securely through the Internet. This protocol
thereby establishes a standard point-to-point connection in B2B (Business to
Business) document transactions. Stated another way, AS2 provides the
means by which vendor applications communicate EDI (Electronic Data
Interchange) documents, or other data such as XML, over the Internet using
HTTP (Hyper Text Transfer Protocol). Further, AS2 defines a security
system that wraps the data in an envelope with a digital certificate.
Recently, this AS2 protocol was adopted by Wal-Mart
the worlds largest retailer for their trading partners. And,
protocol is available through the use of a software package named LexiCom developed by Cleo Communications.

Secure, Automated e-Transfer
The LexiCom software package lets trading partners securely transfer
critical business documents to and from their widely distributed trading
partners over the Internet, VANs, or other specialized TCP/IP networks.
Users can transfer and receive everything from POs, invoices, and shipping
notices to insurance claims, medical records, clinical data, retail
reports, and more. Users can also schedule transmissions to occur
automatically, at whatever intervals required.
Trading Hubs and VANs
- Works with the major trading community
- Uses proven IP protocols FTP, HTTP and EDIINT
AS2 allowing users to communicate with multiple trading partners.
- Integration with the
leading EDI software packages reduces
- Pre-configuration offers quick set-up.
- Operates on PCs, Unix and
- Built-in security protects proprietary
- "100% Java" makes it platform independent.
- Perpetual log file monitors and verifies all
A LexiCom user can take advantage of
pre-configured “hosts,” available for all major trading-partner servers
When a specific host is activated, the user will
find that most set-up information for that host is already entered, so all
that is typically required is to edit the default entries in the input
fields. This significantly reduces installation time. For advanced
users, generic host types are also available, allowing for full
flexibility of configuration.

FAQs Regarding Wal-Mart and their AS2 Requirement
At present, we use 3780 BSC to communicate with Wal-Mart. Our PC dials to a
dedicated phone number in US according to pre-arranged schedule. After login
Wal-Mart's mailbox, it runs a few scripts to send and receive files
automatically. What will the workflow be after moving to AS2?
AS2 protocol that Wal-Mart will be using is part of a "push" technology that
will require your department to have your PC up and running 24 hours a day, 7
days a week because they will be contacting you (versus you contacting them
which is the current case). Other than this change, the rest of your "system"
can still be automated.
Question. Our system is developed internally.
How could we integrate AS2 into it? Which package should we buy? The
transmission now is fully automated. We wish to keep this feature in AS2.
You should purchase the base LexiCom software that includes the AS2 protocol
(alone with other protocols if you need them like FTP, sFTP, HTTP, HTTPs,
etc.) . The LexiCom package can be fully automated just like your current
system. The exact LexiCom package that you need to purchase will depend on
whether your operation deals with other companies that will require the AS2
protocol. If Wal-Mart is the only one, then the standard package would be okay.
operation anticipates using AS2 with other companies in the future (e.g.,
Meijer's, K-mart, J.C. Penny, Target, etc.), then, again,buy the base LexiCom
package and add other companies for a small additional charge.
The web-page says AS2 is for WalMart US and Canada. We are interfacing with
WalMart Germany and ASDA at the same time. Shall we support AS2 for US and CA
and 3780 for Germany and ASDA concurrently?
The LexiCom AS2 package has not been set-up to include Wal-Mart Germany. The
base LexiCom will operate for Wal-Mart US, Canada, and SAMs Clubs. Wal-Mart
Germany may not, in fact, be included in the move to AS2 at this time. You
better check with Wal-Mart Germany to get the correct answer to this question.
Same answer applies for other operations like the ASDA - contact them and ask.
When required you can continue to use your 3780 BSC communication linkages.
When shift from 3780 to AS2, is there any change on WalMart side that should be
coordinated together? Is it done country-by-country or one-for-all?
This question, I believe, has been already answered above.
Is there any exact plan as to when the 3780 will be phased out?
We have been told unofficially by Wal-Mart that the old 3780 protocol will
probably be around for a year. Nevertheless, when they advise their specific
suppliers to move to AS2, they do not mean to say you have an option to keep
using 3780 for a year. They will want to you move to AS2 within a "reasonable"
time frame. "Reasonable" would probably be defined as 30 to 90 days after your
operation is notified to make the make the switch to AS2.
Are there other options except 3780 and AS2?
Supposedly, in the case of Wal-Mart, there is no "option" at all except to use
AS2 (at least in the North American Market). Wal-Mart is phasing-out the older
Where can I
get more technical details about AS2 and LexiCom so that I could study how much
SCB will change for it?
AS2-LexiCom web page pretty much covers what you need to know. However, you can
always order a 30 day full version "DEMO" copy of LexiCom where you would have
access to more technical information on the CD-ROM itself. If you want a DEMO
package sent to you - please advise us as to the exact/specific address where we
should sent it.
Question: On a Win2003
server does this just need IIS loaded or is there some other supporting
software I need to be aware of? Is there anything we need to be aware when
building the server for this software?
Answer: No, you don't
need IIS. IIS is an HTTP SERVER. The EBMX HTTPs program
is an HTTP CLIENT. The only thing you need other than the EBMX HTTPs
software is the latest version of the java runtime environment.
How we could integrate this new
AS2 software in our actual network structure. The first server we have on
our DSL line is a firewall + HTTPS, we would like to put the "AS2 Server" behind
this machine. Is that possible ? Would it be a problem to receive file?
Answer: You must
be able to create a network address translation mapping from the external IP
address and HTTP port on the firewall back to the machine running AS2 within the
network. The IP address must be static not dynamic
Question: We have to
provide a URL+URI to upload their files. Can you handle this?
Answer: Yes. AS2
requires a static IP address and open Inbound tcp/http port...usually selected
from ports above 1023.
Regarding the need to able to make a network address translation mapping, as we
have apache in the front machine, can this be done by translating a specific
mapping of a URL is accomplished by a DNS (domain name server) and can be done
as suggested by Armelle. This URL must always point back to the machine that has
the AS2 software and must also specify the chosen inbound open HTTP or HTTP/s
port used by the AS2 listener. Cleo (LexiCom) does not provide DNS services...that would
be the customers responsibility.
your AS2 provide a transfer receipt of type SHA-1?
Answer: Yes. LexiCom
supports SHA-1 MDNs (receipts).
your AS2 package also use encryption to send and receive the files (I guess this
is done by the use of HTTPS protocol)?
Encryption within most AS2 environments is done using S/Mime not
HTTP/s...LexiCom supports both.
Question: How much can we integrate
your software into our own developments. For example, is there an API in
Java allowing to send a file by AS2 or does it starts only by a command line?
Answer: LexiCom has and Java-based API as
well as a command line interface ....most of the integration we have worked with
have been file based integrations.
will support AS3 later this year. Simply stated...
transport is S/MIME over FTP.
AS3 is a
client/server model like FTP (as opposed to "peer-to-peer" like AS2).
MDN's (receipt notifications) like AS2.
are a few additional comments regarding AS3...
client initiates "sends" and "receives" just like FTP.
Client-side AS3 does not require a listener to be always aware of
inbound traffic, so a persistent Internet connection is NOT required.
Dial-up Internet connections are fine. (AS2 does require a persistent
connection for the listener.
details of the spec are far from solid. Cleo helped design the initial
Drummond Certification definition scheduled for late this year. There
are still a number of questions that need to be resolved.
is a short excerpt from our current internal AS3 specification that might be
family of secure MIME-based protocols includes AS1 (SMTP), AS2 (HTTP), and
AS3 (FTP). AS1 was and still is available from a number of companies, but
is not widely used. Cleo LexiCom does not support AS1. Since its
inception only a few years ago, AS2 has become an established, proven
peer-to-peer solution. Some proprietary implementations of AS3 exist, but
not until later this year will Drummond Group host the first AS3
certification tests. During this certification period, the protocol will
in essence be standardized.
original drafts outlined AS3 in a peer-to-peer (push/push) model like
AS2. However, using AS3/FTP peer-to-peer causes more security issues than
AS2/HTTP (because there are more ports involved) and has no advantages
over AS2/HTTP. Because of this, Drummond Group will certify AS3 only in
a client/server (push/pull) model. This distinguishes AS3 and gives it
viability partly because, with a client/server model, dial-up Internet
users can now use EDIINT.
be adding support for AS3 to our LexiCom product and will be in the first
round of testing with the Drummond Group later this year.
