Sun Microsystems 1 manual Start up a Windows 2000 command shell window

In order to load this EEPROM image into CRef, do the following:

1.Start up a Windows 2000 command shell window.

2.Enter the following command into the command prompt, without line breaks:

C:\>%JC_HOME%\bin\cref.exe -p <port number> -i %MIDP_HOME%\bin\jc_eeprom_image

In the command line above, the <port number> should be one of the ports specified in the com.sun.midp.io.j2me.apdu.hostsandports property in the internal.config file. (For more information on the internal.config file, see “The internal.config File” in this chapter.)

Once you have entered the cref.exe command above, you should see output as shown in CODE EXAMPLE 1.
