APPENDIX
B
Command Line Reference
This appendix describes how to operate the J2ME Wireless Toolkit from the
command line and details the steps required to build and run an application. It also
describes the J2ME Wireless Toolkit certificate manager utility, called MEKeyTool,
and the MIDlet signing utility, called JAD Tool (Java Application Descriptor Tool).
B.1 Prerequisites
Before building and running an application from the command line, verify that you
have a version no earlier than 1.4.2 of the J2SE SDK. Run the jar.exe command
(make sure the command is in your PATH) and then run java -version at the
command line to verify that the version of the J2SE SDK that is actually being used
is 1.4.2.
For more examples, see the files build.bat and run.bat in the bin directories of
the demonstration applications. You can find these files under the
{toolkit}\apps\<demo>\bin directory where {toolkit} is the installation directory of
the J2ME Wireless Toolkit and <demo> is the name of one of the demo applications.
B.2 The Development Cycle
For a full description of developing MIDP applications, see Chapter 2, “Developing
MIDlet Suites.” This section describes how to accomplish each of the steps in the
development cycle from the command line.
