Hello Roger,
I'm not aware of simpler ebMS 3.0 client-only
implementations. The implementations I know about support both
the client and server functionality. If they offer a client-only option, it is a
lower-cost commercial option with turned off functionality that doesn't reduce
the code base size. SOAP libraries for security and reliability
needed to implement ebMS tend to depend on these larger SOAP frameworks.
The AS4 profile doesn't require reliable
messaging, but still does require WS-Security. I agree that
an ebMS 3.0 client profile that drops even that requirement (and
just uses TLS) seems very simple to implement.

product to improve reliability of the client-pull mechanism. The client
software polls our server to retrieve messages from a user’s mailbox (i.e. it’s
entirely internal to us). Most likely a small, proprietary enhancement
will fit the bill, but this prompted me again to look at possible ebMS open
source products / libraries for implementing this. Since I noted ebMS 3.0
now extends to the client-pull message pattern, I wondered if code implementing
that might now be available. (Code that included an embedded data store
for transactions using a lightweight embedded database on the client side might
also be a plus, though it’s not a critical requirement right
now). I’m not finding anything quite like that – does it
exist? What I do see is the fairly recently released Holodeck
project (May 2010) – but despite being ebMS 3.0 based, it seems not to include
any client-side implementation (with tomcat and axis2 as prerequisites, even for
the ‘light’ version). The Hermes / freebxml project includes the ebMail GUI client,
but it seems designed more as a real GUI with a plug-in model, rather than as a
set of libraries to use as a new messaging core for an existing
product. BTW, for those interested, Traxian’s is an easy e-commerce
integration solution for B2B and B2C transactions, initially focused on
QuickBooks. It includes a “social / viral” model for radically easy,
low-friction setup. Regards, Roger Bass |
