Java and XML Basics, Part 1
In a previous article (XML Basics Part One);we had a brief look at XML. However, as stated in the article, XML itself is worth nothing without the set of APIs that are generated-it would simply be just another fancy form of CSV, that is, a proprietary data format! My aim in this set of articles is not to actually reveal XML in its every detail, but rather have a look at the implications of XML in today’s technologies. That’s why the previous article only sheds a little light into the insights of XML, which included some terms and technologies you will be confronted with the moment you step in the XML arena.
JAXP and the Need for Standards
Although it may sound like it, this is not another chapter about Jack and the magic Beans. Instead it will reveal one of the basic XML APIs in Java: the parsing API.

Cross the Gap Between PHP and Java
These days, using sophisticated application frameworks to build your network server applications is understandable, but sometimes such frameworks are overkill. When you strip networking down to its bare essentials, network sockets offer lot of flexibility and simplicity. With a little communications programming between PHP and Java, you can establish an extensible layer that handles the annoying details of creating a custom network protocol.
As you'll see, PHP is not only excellent for quick-and-dirty scripting. More and more developers also are using it to build sophisticated Web applications. Java, of course, has been used to build Web applications for years, but as anyone who has used a Java-based Web framework knows, it isn't the easiest technology to use.

BASIC and FORM-based Authorization in Your Web Application
In the development of any, more-or-less big Web application, every developer collides at times with the problem of how to bear certain parts of the application in the protected area and to divide access to them by login and password. How do you carry out authentication? Actually, there are a lot of variants. In this article, we do not present a problem to consider all possibilities; our purpose is to learn how to work with the simplest yet rather convenient method of authorization. We will talk about BASIC and FORM-based authorizations. As a Web server, we will consider Tomcat, which provides BASIC and FORM-based authentication through server.xml and web.xml files; the use of a j_security_check form (for FORM-based) in a JSP page that requires two parameters j_username and j_password; and specifying roles (groups) within the SQL database. As you can see, it's a flexible, useful, and necessary set of capabilities.

Web development made easier
You might think a company that has a virtual lock on the professional Web development market would be content to rest and enjoy the fruits of its labor. Only a year after releasing Studio MX, however, Macromedia Inc. has come out with an upgrade.
Studio MX 2004 is a far cry from the major overhaul that marked last year's introduction of the MX line, but that's not to say that it doesn't have its share of enticing enhancements. At the top of the list are Dreamweaver's cascading style sheet support, which lets users more accurately develop complicated layouts and designs; Flash's continued transformation into a full-scale Web animation and development tool; and more improvements to the MX 2004 interface and overall product integration.

Setting up your ASP .NET server (IIS)
Before starting, be sure you have .NET Framework installed. If not, you can install it using Windows Update or download the package and install manually.
ASP runs inside IIS (Internet Information Services). Therefore first you should install IIS (under Windows 2000, Windows XP or Windows 2003), of course if it isn't already installed. Usually, you can install it from Control Panel / Add or Remove Programs / Add/Remove Windows Components.
