The first question that you may have is, "What is Enhydra?" Enhydra is an open source application server written entirely in Java. It supports many standards, including XML, HTML, Java Servlets, and JavaServer Pages (JSP).

Assuming you have managed to arrange hosting of your .wml files, as described in the previous step, you are now ready to test that they are accessible over the internet. The obvious way you could do this is to just open the page in the WAP browser on your 3510.

"The easy way to develop WAP applications"

Coldbeans launched HTML transcoding service. Pure Java application allows to Web developers make their sites readable on wireless devices supports WAP protocol.

We discuss an approach for targeted transformations of content to open sets of devices. The key element of this approach is the RDF Model that represents devices as sets of generic features and represents content resources as sets of components. The other key element is the RDF server utilizing this Model to support transformations across different devices and presentation channels.

Wireless Markup Language is the language for authoring WAP documents. Although WML merits a long tutorial, this summary should provide enough background for those knowledgeable about HTML and XML.

This includes all existing include files of the Formatting (FMT) category, i.e. all includes with prefix wml::fmt. The following files currently exist:

Using WAP with WebLogic Server

The URL.resolve function appends a relative URL to the base URL to create and return an absolute URL. This is referred to as resolving the URLs.

On most systems, Builder Xcessory accesses widgets by loading a shared library when the widget class is first accessed. To load widgets dynamically using Builder Xcessory, the following two requirements must be met:

Building Wireless Applications Using Java and XML

While XHTML MP enables the creation of visually appealing pages, developers with a background in WML or HDML will find that some of the features available in those mark-ups are no longer available. Because of this, migrating from WML/HDML to XHTML cannot be automated and a more reliable and functioning application will result from doing it manually with the help of the information presented here. This chapter gives an overview of the differences between WML/HDML and explains which alternative constructs can be used for features that are no longer supported.

A few years have passed since the peak of the WAP hype. Since then, we have not heard much about it. Now that WAP 2.0 is reaching the mainstream, it is worth another look. Most of the current devices support the old standard, WAP 1.2.1. WAP 1.2.1 is available on Sony Ericsson phones such as the T100, T200 and T600.

Topics in Wireless Networks

Unlike HTML, WML supports a limited use of variables (note that this has nothing to do with the scripting language WMLScript - these variables can be used in WML proper). This lesson covers how one uses WML variables.

Chapter 4 teaches you the fundamentals of using WMLScript and tying it to WML to create applications. The two examples below are used together to create a single functional card.

Here you can grab the tarballs of complete distributions containing major releases. Not all interim releases are archived, only the initial release of a revision (patchlevel 0) and the latest release on this revision (highest patchlevel) are kept. For all other releases first grab a tarball and then apply one or more of the patch files.

The UP.Link platform, shown in Figure 1-1 below, provides subscribers with secure, wireless access to a wide array of Internet and other network services using data-capable wireless phones or personal digital assistants (PDAs). For the purposes of this documentation, these specially-enabled handheld devices are called UP.Phones.

Like conventional Web sites, a WML service usually consists of a set of screens that present information with which users can interact. In WML, these screens are defined as a set of one or more cards. The actual correspondence between cards and screens depends on the device display size, as well as how you define your cards. On larger devices, the UP.Browser may present a card as a single screen. On smaller devices, the same card may appear as multiple screens. The key to constructing an efficient and easy-to-use WML service is determining the best way to:

A task specifies what action to perform when an event, like entering a card or selecting a link, occurs.
