XML is rapidly becoming the way applications communicate. Because it isn't
one language but a means to create many languages, it can play many roles in
application integration and data exchange. In this article I'll explore some
of the varied roles that XML can play by developing a simple middleware
application that serves up data from a database.
The application (see Listing 1) uses XML in three ways: Requests from clients
are encoded in XML. Data sent back to a client is encoded in XML. The
database itself contains data marked up in XML. The application is written in
OmniMark - a 12-year-old language with a long history in the SGML community -
which became a free language in May 1999. It's based on the streaming
programming model pioneered by OmniMark and subsequently adopted by SGML and
XML translation languages like DSSSL and XSL. Streaming is also the principle ... (more)
This article demonstrates how to leverage XML, LDAP, and Java technologies to
create a Web-based directory lookup tool. This tool is built with a publicly
available implementation of a Java/XML publishing framework called Cocoon
(available at http://xml.apache.org/cocoon) and an LDAP server (we tested
with the iPlanet Directory Server on Solaris). Using these off-the-shelf
modules we can focus on the role of XML as a database-neutral format for
data, and how it enables a flexible application architecture that lets you
support both wireless and wireline clients. We'll demonstrate this with a WML
client (WAP phone simulator on Windows) and an SVG client (Adobe's SVG
plug-in for browsers on Windows).
This article assumes the reader has a fairly good knowledge of XML and a
working knowledge of XSL stylesheets. We'll first introduce WML (Wireless
Markup Language) and SV... (more)
Integrating mainframe applications into an SOA often carries the burden of
dealing with metadata in the form of Cobol Copybooks. This metadata converted
to an XML Schema format can be useful for a range of applications (from
validation to creation of services). This article explains how to automate
the conversion from Copybooks to XML Schema using regular expression logic.
Cobol Copybooks 101
Mainframe metadata is usually defined using a subset of the Cobol language.
Mainframe developers call these descriptions Copybooks. Cobol data definition
is based on a hierarchical structure composed by two different types of
items: Elementary Items and Group Items.
Elementary Item is the name Cobol assigns to a data item that is not further
subdivided (analogous to variables in other languages). Elementary Items are
composed of: a Level Number, a Data Name, and a Picture Clause.... (more)
This article shows how to build database Web applications using Oracle, two
open-source frameworks, and MetaBOX software. Building database Web
applications is commonly a repetitive task; many such applications are based
on insert/delete/update statements of tables in a form of simple rows,
multiple rows, or master/detail combinations.
To make this kind of application, many products offer different solutions -
we can divide them into procedural or declarative approaches. These products
provide wizards or code generators to help developers in the developing
stage.
Depending on which technologies these generators use - pure HTML or XML -
developers need to work more or less to get the desired output and maintain
their applications. The procedural approach requires developers to know what
they need and how to obtain it. Code generators for this approach generally
use... (more)
"What does the future hold for IT?" It's a burning question that everyone's
asking, but who can answer? At XML-Journal, we went straight to the experts -
the world's brightest and most prescient i-technology professionals - and
asked them what they expect in the coming year for IT in general and XML in
specific.
Industrys stakeholders - software vendors, developers, technology investors,
and users alike - are looking forward to the year ahead with renewed vigor.
The buzz is around XSL, Web services, and the service-oriented architecture.
The benefits of XML are clear...and in 2004 they'll become even clearer.
Following are some of the predictions we received from industry leaders...if
they are an indication of what's to come, it's going to be a great year.

Title: Re: Is "markup" a noun or a verb? Do you "marku
Well then, dal, I’d say if you already have those critters, you applied
markup to 132.
Verb. You selected the tag to mark up the string. That selection limits
the space of the transform, that is, the number of rules in which that tag
name may be found. Choice of choices or limits on the tree neighbors this
tag has by intension. Meaning is deliberate, not probabilistic.
Is a tag (the noun) semantically as rich as markup (the noun)?

A question came up on an internal mailing list regarding getting the
configuration off of the LTM into a format that can be parsed by an external
tool. In this case, the request was for an XML format of the BIG-IP
configuration. With iControl, It’s fairly simple to query configuration
objects and it’s just a matter of throwing in a few print statements to
build a XML document of the object hierarchy.
This article will show you how to query the list of LTM virtual servers and
their child properties and objects and then export the values into XML.
Initialization
I’ve implemented this sample in Perl, but it just as easily could have been
written in any language you prefer. The benefit of perl is that it can be
run from the command prompt on the BIG-IP itself.
the script starts with the normal perl declaration and variable
assignments. The input parameters are valida... (more)

The precious oil is extracted from the seeds of prickly pear cactus plant. After taking out the seeds from the fruits, they are adequately dried and then cold pressed to obtain the oil. Indeed, the prickly seed oil is quite expensive. Well, that is understandable when you consider the fact that the seeds are really tiny and each seed contain only about 5% of oil in it at most, plus the seeds are usually handpicked from the fruits. This means it will take tons of these seeds to produce just one bottle of the oil for commercial purpose. But from its medical properties to its culinary importance, skin lightening, moisturizing, and protection abilities, down to its extraordinary hair care properties, prickly seed oil has got lots of excellent rewards for anyone who pays the price.
