# jjs-openjdk11(1)

Invokes the Nashorn engine.

## NAME

jjs - Invokes the Nashorn engine.

## SYNOPSIS

```
jjs [options] [script-files] [-- arguments]
```

*options*

One or more options of the **jjs** command, separated by spaces. For more information, see Options.

*script-files*

One or more script files which you want to interpret using Nashorn, separated by spaces. If no files are specified, an interactive shell is started.

*arguments*

All values after the double hyphen marker (**--**) are passed through to the script or the interactive shell as arguments. These values can be accessed by using the **arguments** property (see Example 3).

## DESCRIPTION

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

## OPTIONS

The options of the **jjs** command control the conditions under which scripts are interpreted by Nashorn.

- \-cp *path* -classpath *path*

  Specifies the path to the supporting class files To set multiple paths, the option can be repeated, or you can separate each path with a colon (:).

- \-D*name*=*value*

  Sets a system property to be passed to the script by assigning a value to a property name. The following example shows how to invoke Nashorn in interactive mode and assign **myValue** to the property named **myKey**:

  ```
  >> jjs -DmyKey=myValue
  jjs> java.lang.System.getProperty("myKey")
  myValue
  jjs>
  ```

  This option can be repeated to set multiple properties.

- \-doe --dump-on-error

  Provides a full stack trace when an error occurs. By default, only a brief error message is printed.

- \-fv --fullversion

  Prints the full Nashorn version string.

- \-fx

  Launches the script as a JavaFX application.

- \-h -help

  Prints the list of options and their descriptions.

- \--language=\[es5\]

  Specifies the ECMAScript language version. The default version is ES5.

- \-ot --optimistic-types=\[true\|false\]

  Enables or disables optimistic type assumptions with deoptimizing recompilation. Running with optimistic types will yield higher final speed, but may increase warmup time.

- \-scripting

  Enables shell scripting features.

- \-strict

  Enables strict mode, which enforces stronger adherence to the standard (ECMAScript Edition 5.1), making it easier to detect common coding errors.

- \-t=*zone* -timezone=*zone*

  Sets the specified time zone for script execution. It overrides the time zone set in the OS and used by the **Date** object.

- \-v -version

  Prints the Nashorn version string.

## EXAMPLES

**Example 1** Running a Script with Nashorn

```
jjs script.js
```

**Example 2** Running Nashorn in Interactive Mode

```
>> jjs
jjs> println("Hello, World!")
Hello, World!
jjs> quit()
>>
```

**Example 3** Passing Arguments to Nashorn

```
>> jjs -- a b c
jjs> arguments.join(", ")
a, b, c
jjs>
```
