CLDC Reference Implementation
kvm [options] classfile [args]
kvm command is a reference implementation of
a Java virtual machine that meets the requirements of the CLDC
specification. KVM can load classes from a directory structure in a
local file system or from a set of JAR files. In order to reduce
memory footprint and application startup time, it is usually built
with a copy of the core Java libraries preloaded, using a technique
known as ROMizing.
kvm command provided with the CLDC reference
implementation does not provide support for Java-level debugging.
However, a second version,
is provided. This version can provide this capability in conjunction
with the KVM debug proxy (
kdp), together with a
set of additional command-line options that can be used to request
debug trace information to be written to the standard output stream.
It is also possible to build a version of the KVM that includes an
implementation of a Java application manager (JAM) that can be used
to load applications over a network and install them in local
filestore. This feature is usually not used, however, since most
systems prefer to incorporate more sophisticated application manager
software of the type provided by the
The following options are available in all versions of the KVM:
