WML Applications using JavaServer Pages (JSP) Setting Things Up

The WAP environment partially supports the protection of certain directories and files (and even commands) through the HTTP protocol. The system is identical to what you would use on a normal web page, and is known as Basic Authentication.

These include files provide the additional higher level features. There functionality is based upon both the core languages and the auxiliary programs. (They can be explicitly loaded when needed via #use or #include directives).

The following examples provide one or more examples for each of the WML TransformationBeans provided with webAF software. The JSP source provides the complete WML code.

Wireless Application Protocol (WAP) is an open standard and application environment for wireless information and telephony services on digital mobile phones specified by WAP Forum.

WAP and Wireless Technologies

WML supports two kinds of user input: entering text and selecting from a list. The following sections describe how to both prompt the user and handle the response.

WAP/WML templates require a php Content-Type header to be passed along with the template. The easist way to do this would be to write a custom function that prints the header. If you are using caching, that won't work so we'll do it using the insert tag (remember insert tags are not cached!) Be sure that there is nothing output to the browser before the template, or else the header may fail.

WML supports Cascading Style Sheets. In particular, you can specify the class attribute of HTML elements in a variety of ways.

This is a quick guide to reading API documentation; the type of documentation the usually comes with PHP class libraries.

This chapter provides reference information for WML 1.1 elements and attributes, and Openwave extensions to WML. The elements are listed in alphabetical order, with available attributes shown for each, and required attributes in bold.

When we loaded that first WML example into the UP.Simulator, we really only paid attention to what happened in the window containing the 'phone':

Although Internet usage is rapidly growing, mobile phones usage is soaring, and far faster in Europe and the Far East than in the United States. According to IC Insights, cellular phone shipments reached 258 million in 1999 and are projected to hit 356 million units in 2000.

At last we arrive at the nitty-gritty of wireless applications -- WML. This section should give you a flavor of how WML works, but it falls far short of a complete education.

With millions of mobile phones already in use, its no wonder that over £22 billion pounds was raised by the recent auction of third generation mobile phone licences. Promising 2Mbps connections, the next generation of mobile phones is going to change the way we see the Internet.

WML is a language based on XML (eXtensible Markup Language). The official specification of WML is developed and kept for the WAP Forum, a partnership established for the Nokia, Phone.com, Motorola and Ericsson. E it defines the used syntax, 0 variable and elements in WML archives.

The components of the WAP specification correlate to components of the wired Internet. Wireless Markup Language (WML), for example, defines the way a document appears in a microbrowser, just as HTML describes how documents appear in conventional Web browsers.

The widget meta-language facility (WML) is used to generate changeable components of the user interface language (UIL) compiler, depending on the widget set. Using WML, you can add new widget UIL support to the AIXwindows widget set or add support for a totally new widget set.

WAP homepages are not very different from HTML homepages. The markup language used for WAP is WML (Wireless Markup Language). WML uses tags - just like HTML - but the syntax is stricter and conforms to the XML 1.0 standard.
