Wireless application development has the following characteristics:
- multi-platform and multi-device support, since no single device can serve entire organization's needs
- multi-wireless network (especially wide area) support
- multi-backend application and database support
- integration with web application server platforms
There are a number of application platforms for supporting mobile applications. However, Java Enterprise Edition (J2EE) does support multiple operating system platforms. It is becoming an important application development platform for non-Microsoft environments. In fact, IBM's Websphere application server utilizes J2EE. Current (01/20001) version of J2EE is 1.2. New version of J2EE 1.3 has stronger XML support.
Expected features in J2EE 1.3
- Stronger Java XML parsing
- Connector specification for integration with back-end applications
- Enterprise Java Beans 2.0, including message-driven beans through Java message beans
- XML view of Java Server Pages
- Improved custom tag library APIs
Resources & Vendor Products
- VisionAir's DRE Wireless Gateway - based on an open architecture

Goforexam Advisory: J2EE is gaining gradual acceptance as an application development platform of choice. Business application developers should also consider higher-level tools available from IBM, Oracle, Sybase iAnywhere, Microsoft, @Hand, etc.. The latter category of tools continue to have superior backend integration with legacy systems from these vendors. If these higher-end tools are based on Java or have hooks into Java beans and Java functional modules from other vendors, it becomes easier to utilize Java-based software platform from multiple vendors.
