JVM Interfaces
IMP-NG
Connected Limited Device Configuration (CLDC)
J2ME, 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 the File I/O API and the AT command API. Documentation for J2ME and
CLDC can be found at http://java.sun.com/j2me/. Documentation for the other APIs is found
in .../ Java doc [6].
4.2.7.1
IP Networking
IMP-NG provides access to TCP/IP like 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 [4] or by parameters given to the connector open method, see Java doc
[6].
4.2.7.2
Media
TC65 supports only a subset of the optional media package, see Java doc [6].
4.2.7.3
Others
TC65 does neither support the PushRegistry interfaces and mechanisms nor any URL
schemes for the PlatformRequest method. See Java doc [6].
