Each property setting must use one of the flags in the table below. There is no space between each flag and its value. Note that certain flags are used only for JavaOS properties, while others are used only for system properties.

Table 4-7 Property Flags






Used to define a JavaOS property. The property name and value are stored in the JavaOS properties object. The names of properties set with this option always begin with javaos. Example: -djavaos.kbd=UKPS2



Used to define a system property. The system property and value are stored in the global system properties object. Example: -Duser.timezone=PST.



The JavaOS property is set to the given value if it has never been set before. If the property already has a value, then its current value is appended with a semicolon and the value. Example: -ajavaos.printservice.lpd.printer=printer2

This example sets the property javaos.printservice.lpd.printer to printer2 if the property has no current value. If the property already has a value (say, printer1), the new value is appended (printer1;printer2).

This flag is useful if you are building the value of a property from multiple places using the -i option below. Note that this property can itself be a semicolon-separated list of values; the entire list is added or appended as described above.



This works just like the -a option, except that it sets system properties.

Note that -a and -A are equivalent to -d and -D, except for the append behavior.



Used to undefine a JavaOS property. 



Used to undefine a system property. 



The HTTP URL is expanded and the file referenced by the URL is itself evaluated as if it were a JavaOS command line. Properties are stored one per line in this file. One file can use -i to include another file. There is currently no check on infinite recursion.

Properties will be interpreted as the JavaOS command line, which is a formatted text string of any length that is interpreted when the JavaOS software boots. The command line can include:

The syntax of the command line is as follows:

prop_setting1 prop_setting2... prop_settingn -- arg1 arg2... argn

where prop_setting is a JavaOS property setting and arg is an argument. Property settings and arguments are separated by two contiguous hyphens.
