MobileDev
MobileDev is the first Wireless Development Environment (WDE) specifically
for WAP Internet applications. Its innovative open-ended development model
integrates a graphical application mapper with a wizard interface and a rich
tool set. MobileDev
supports WAP technologies like WML, HDML, Microsoft Active Server Pages (ASP),
Perl and Java Server Pages (JSP).
Using the GUI application mapper to show the relationships between objects, developers can quickly outline the components of a WAP application. Then they can take advantage of wizards that generate Decks and Cards in both WML and HDML, and use MobileDev's code builder to write WML/HDML syntax that complements the wizard-generated code. The integration of the application mapper with wizards and the code builder provides a seamless WDE that delivers results fast.
MobileDev comes complete with its own powerful integrated runtime engine, MobileDev Server Script. Server Script can quickly create prototypes or build full-blown business WAP applications that can be natively connected to an RDBMS. MobileDev WDE is also designed to support development in ASP, JSP, Perl or other template-based server technologies.
