4.2.7 JVM Interfaces

IMP-NG File API AT Command API

Connected Limited Device Configuration (CLDC)

J2ME

Figure 2: Interface Configuration

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 [5].

4.2.7.1 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 [3] or by parameters given to the connector open method, see Java doc

[5].

4.2.7.2 Media

TC65 does not support the media package. See Java doc [5].

4.2.7.3 Other Interfaces

TC65 supports neither the PushRegistry interfaces and mechanisms nor any URL schemes

for the PlatformRequest method. See Java doc [5].
