NAME

6       jjs - Invokes the Nashorn engine.
7

SYNOPSIS

9           jjs [options] [script-files] [-- arguments]
10
11       options
12           One or more options of the jjs command, separated by spaces. For
13           more information, see Options.
14
15       script-files
16           One or more script files which you want to interpret using Nashorn,
17           separated by spaces. If no files are specified, an interactive
18           shell is started.
19
20       arguments
21           All values after the double hyphen marker (--) are passed through
22           to the script or the interactive shell as arguments. These values
23           can be accessed by using the arguments property (see Example 3).
24

DESCRIPTION

26       The jjs command-line tool is used to invoke the Nashorn engine. You can
27       use it to interpret one or several script files, or to run an
28       interactive shell.
29

OPTIONS

31       The options of the jjs command control the conditions under which
32       scripts are interpreted by Nashorn.
33
34       -cp path
35       -classpath path
36           Specifies the path to the supporting class files To set multiple
37           paths, the option can be repeated, or you can separate each path
38           with a colon (:).
39
40       -Dname=value
41           Sets a system property to be passed to the script by assigning a
42           value to a property name. The following example shows how to invoke
43           Nashorn in interactive mode and assign myValue to the property
44           named myKey:
45
46               >> jjs -DmyKey=myValue
47               jjs> java.lang.System.getProperty("myKey")
48               myValue
49               jjs>
50
51           This option can be repeated to set multiple properties.
52
53       -doe
54       --dump-on-error
55           Provides a full stack trace when an error occurs. By default, only
56           a brief error message is printed.
57
58       -fv
59       --fullversion
60           Prints the full Nashorn version string.
61
62       -fx
63           Launches the script as a JavaFX application.
64
65       -h
66       -help
67           Prints the list of options and their descriptions.
68
69       --language=[es5]
70           Specifies the ECMAScript language version. The default version is
71           ES5.
72
73       -ot
74       --optimistic-types=[true|false]
75           Enables or disables optimistic type assumptions with deoptimizing
76           recompilation. Running with optimistic types will yield higher
77           final speed, but may increase warmup time.
78
79       -scripting
80           Enables shell scripting features.
81
82       -strict
83           Enables strict mode, which enforces stronger adherence to the
84           standard (ECMAScript Edition 5.1), making it easier to detect
85           common coding errors.
86
87       -t=zone
88       -timezone=zone
89           Sets the specified time zone for script execution. It overrides the
90           time zone set in the OS and used by the Date object.
91
92       -v
93       -version
94           Prints the Nashorn version string.
