Process arguments as would a normal Java program. Also create a new Context and associate it with the current thread. Then set up the execution environment and begin to execute scripts.

exec

public static int exec(String[] origArgs)

Execute the given arguments, but don't System.exit at the end.

processFiles

static void processFiles(Context cx,
 String[] args)

evalInlineScript

static void evalInlineScript(Context cx,
 String scriptText)

getGlobal

public static Global getGlobal()

getShellScope

static Scriptable getShellScope()

getScope

static Scriptable getScope(String path)

processOptions

public static String[] processOptions(String[] args)

Parse arguments.

initJavaPolicySecuritySupport
