David, (or perhaps Jacques / Pim?) My company, Traxian, is looking at some updates to our 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 |
