Functional Description

Java Virtual Machines from Trolltech partners are available for Qtopia. Java applications integrate seamlessly providing Java content with a native Qtopia look and feel.

A number of JSRs are relevant to Java integrated on Qtopia Phone:

JSR185 JTWI 1.0 (includes JSR30, JSR 118, JSR 120, JSR 135)
JSR 139 CLDC 1.1
JSR 184 3D Graphics
JSR 75 PIM/File Connection
JSR 205 WMA 2.0
JSR 82 Bluetooth/OBEX
JSR 177 Security
JSR 172 Web Services
JSR 179 Location Based Services
JSR 180 SIP
JSR 211 Content Handler
JSR 226 Scalable 2D Graphics
JSR 229 Payment
JSR 234 Advanced Multimedia
JSR 238 Mobile Internationalization
JSR 248 Mobile Services Architecture (All of the above JSRs)
JSR 230 Data Sync
VSCL Vodafone Service Class Library
DoJa i-mode Java Applications

There are also "container" JSRs, which include some selected JSR and define more precise optional features. Those JSR are usually used as "minimal" requirement in customers RFIs

Most of above JSR are now included in the "container" JSRs 248, also known as MSA. MSA is split into "MSA subset" and "MSA full set". According Sun "MSA subset" is likely to become mandatory by summer 2007.

Older, but still in-use "container" JSR is 185 also known as JTWI. There is JTWI 1.0 and 2.0. The main difference there is in messaging - 1.0 uses SMS and 2.0 uses MMS.
