March Java Users Meeting - Web Services

["Burr Sutter" <sutter@bravepoint.com>]

Next Generation Web Services: Using Apache Axis to Make Web Services
Reliable



This month's meeting will be Tuesday March 18th from 7 to 9:30 PM. Our
meeting location for this month will be at the Crown Plaza Ravina Hotel
across from Perimeter Mall off Ashford-Dunwoody. This is NOT the Ravina
conference center that we use to meet in a year ago.  The parking garage is
on the left of the hotel. We will also use that 6:30 to 7:00 PM window of
time to have our open discussion.  And the Certification Group normally
likes to meet in the bar for a few moments after the main meeting!



We know that Web Services and anything open source are very hot topics for
our group.  The Crown Plaza offers us a much bigger meeting room so we
should have plenty of available seats this month so please bring out your
friends, cubical neighbors and anyone else interested in the current
state-of-the-art buzz-worthy Java-related tech-stuff!



Apache Axis, an implementation of the JAX-RPC specification, has gained
widespread momentum as the de facto standard for SOAP processing in Java.
This presentation will examine how developers can build applications that
support one-way invocations and request/response messaging using JMS as the
underlying protocol.  The following will also be discussed:

- Current work under way that will allow the Axis API to allow a Web service
client to receive asynchronous callbacks from a remote service using a
variety of protocols, bringing the use of asynchronous Web services beyond
the boundaries of JMS.

The underlying message exchange correlation that enables Apache Axis'
asynchronous capabilities.

- The impact of WS-Reliability and how that can complement a JMS based
infrastructure to provide a reliable web services substrate.

- How the blending together of reliable messaging and web services in the
proper architecture can provide a standards based infrastructure for
integration across the extended enterprise.

Upcoming Meetings & Announcements:
At this moment, we plan to have Chuck Cavaness back in April for a
presentation on OJB (http://db.apache.org/ojb).  And we are looking at May
for the "Guru Night" panel.  This will be a very exciting event that covers
all the latest & greatest best practices for J2EE application development.
What does it take to be the Java guru in your shop?

If you know of any hiring managers please have them contact us for an
announcement at this month's meeting.  We are always open to ideas and
thoughts related to improving the AJUG experience and promoting the Java
development community.

The AJUG Certification Group has recently gotten started with a new "class"
for those people interested in Sun's Java certifications.  They are looking
for a certified Web Component Developer to participate in development of new
curriculum related to this certification.  If you are interested in getting
involved with this group please contact Lee Chalupa at lchalupa@seelink.org.
We will be updating their web page soon to reflect the new strategy for that
group.

We would like to thank Oracle for their presentation on persistence
architectures.  That presentation will be available at www.ajug.org soon.
More information on this topic can be found at

If you are interested in adding/removing yourself from an AJUG email list,
please following the instructions listed here:

As always we'd like to thank our sponsors that pay for the facilities that
we use.  BravePoint (www.bravepoint.com) and Inflow (www.inflow.com).

I look forward to seeing you on March 18th!
