News from IBM developerWorks
An introduction to XQuery
Howard Katz introduces the W3C's XQuery specification,
currently winding its way toward Recommendation status after
emerging from a long incubation period behind closed doors. The
complex specification consists of six separate working drafts,
with more to come.
This article provides some background history, a road map into
the documentation, and an overview of some of the technical
issues involved in the specification. A sidebar takes a quick
look at some key features of XQuery's surface syntax. Code
samples demonstrate the difference between XQuery and XQueryX
and show examples of the surface syntax.

A closer look at SOAP, RPC, and RMI
In this second installation of the Soapbox column, Brett McLaughlin
compares the Simple Object Access Protocol in more detail with RMI
and RPC, and suggests how you can make the best choice among
the three messaging protocols.
He looks at the real-world SOAP implementations from IBM and Microsoft
and examines the limitations of XML -- SOAP's underlying encoding
format -- and the problems involved in it as a full-fledged programming
language. The article includes sample code for RPC and SOAP airline
ticket requests, for side-by-side comparison.

A simple SOAP client
This article describes a simple, general purpose SOAP client in Java
that uses no specialized SOAP libraries. Instead of creating the SOAP
request XML document for you under the hood, this client lets you create
your own request with any XML editor (or text editor). Instead of merely
giving you the remote method's return values, the client shows you the
actual SOAP response XML document.
The short Java program shows exactly what SOAP is all about: opening
up an HTTP connection, sending the appropriate XML to invoke a remote
method, and then reading the XML response returned by the server. Read
