4.2.8 JVM Interfaces
Figure 6: Interface Configuration
Java ME, CLDC and MIDP were implemented by SUN. IMP-NG is a stripped down version of
MIDP 2.0 prepared by Siemens and does not include the graphical interface LCDUI. Siemens
developed additional APIs like the File I/O and the AT command API. Documentation for Java
ME and CLDC can be found at
http://java.sun.com/javame/ . Documentation for the other APIs
is found in [3] .
4.2.8.1 IP Networking
IMP-NG provides access to TCP/IP similarly to MIDP 2.0.
Because the used network connection, CSD or GPRS, is fully transparent to the Java interface,
the CSD and GPRS parameters must be defined separately either by the AT command
AT^SJNET
[1] or by parameters given to the connector open method, see [3] .
4.2.8.2 Media
The playTone method and the tone sequence player are supported. For optimum performance
use notes in the range of 48 to 105. Tones outside this range are affected by audio hardware
filtering (see
[2] ).
Media package is only supported in TC65. See [3] .
4.2.8.3 Other Interfaces
Neither the PushRegistry interfaces and mechanisms nor any URL schemes for the Platform-
Request method are supported. See
[3] .
