7. Web applications
- Low entry barrier
- Nokia Web Tools – includes a full IDE with emulator
- Limited API set compared to Java ME
- Xpress Web App Builder (XWAB)
(for a no-code way of presenting data)

8. Java ME
- Java Platform, Micro Edition
(MIDP/CLDC = MIDlet)
- Java Specification Requests (JSRs) with Nokia extensions
- The recommended environment is the Nokia IDE for Java
- …but NetBeans is OK, too

9. Supported JSRs
- Devices have a comprehensive
list of JSRs
- Nokia Developer Device Spec API
list
- Nokia Ad Exchange
- Nokia In App Purchase
- Maps API for Java ME
