Java Forum / General / February 2007Is the Java language available as freeware?

SignatureKnute Johnson email s/nospam/knute/ > I am looking for a good scripting engine for the MS Windows platform. The Java *Plug-In* is free, as are the development tools, but it is supported on Mac OS and *nix, as well as Windows. Oh well.. better luck next time. ;-) Andrew T. > I am looking for a good scripting engine for the MS Windows platform. Java is free, but its not a "scripting engine". Its a full blown general-purpos programming language. Depending on your requirements, Java may be too heavy-weight. If you want some simple batching, then using .BAT files may be enough (built-in Windows) If you need something a little more complicated than batching, look into a scripting language. Some examples: Perl, Python, Ruby, BASH. If you are doing anything more complicated than that, Java might be the right choice for you. You can download the development kit from Sun, for no charge. >> I am looking for a good scripting engine for the MS Windows platform. > [quoted text clipped - 4 lines] > If you want some simple batching, then using .BAT files may be enough > (built-in Windows) Somewhere between batch files and perl/python/ruby/bash is WSH, Windows Scripting Host. WSH is actually a platform, and languages you can write in include VBScript, JavaScript, and a couple others I don't recall off the top of my head. > If you need something a little more complicated than batching, look > into a scripting language.

Why don't you just recommend he surfs a few pr0n sites with "Install and run anything" turned on? WSH is _horribly_ insecure. Avoid it like the plague. it exists to fill a niche in M$oft's world view (How do we make the ASP languages run from the command line?) rather than because it's a good or trustworthy platform. If you want a "scripting language" for Windows, then I'd strongly recommend Python. Perl works too, as does Ruby. Python and Ruby are also better languages than JScript or VBScript. You might even install Cygwin (good) and then learn Unix shell scripting (usually pretty obsolete, although still worth knowing about). Java is _not_ a scripting language by any means. Groovy is only a useful scripting language if you're already in a JVM-friendly environment, which you're probably not. >>Somewhere between batch files and perl/python/ruby/bash is WSH, >> Windows Scripting Host.

Out of curiosity, what vulnerabilities does writing your scripts in WSH open you up to that writing your scripts in Python/Perl/Ruby/Bash/whatever does not? - Oliver > Out of curiosity, what vulnerabilities does writing your scripts in WSH > open you up to that writing your scripts in > Python/Perl/Ruby/Bash/whatever does not? Ones based on exploits via ActiveX. WSH doesn't even have IE's level of protection here. The problem isn't with the "scripts" -- obviously a trivial bit of Python is more dangerous than a typical piece of JScript in WSH. It's with the very _existence_ of WSH on a machine. If it's there and available, it's an easy route for far too many of Windows' past "We shouldn't really execute this, but hey why not" exploits to find a loophole between a sandbox that's supposed to be locked down and one in which a powerful ActiveX can be run unchecked. As a result, it's just not safe to have it on the machine. >> Out of curiosity, what vulnerabilities does writing your scripts in WSH >> open you up to that writing your scripts in [quoted text clipped - 11 lines] > in which a powerful ActiveX can be run unchecked.

SignatureKnute Johnson email s/nospam/knute/ > I am looking for a good scripting engine for the MS Windows platform. Ever heard of Groovy? > I am looking for a good scripting engine for the MS Windows platform. Java isn't a scripting language. Try Visual Basic Script. > > I am looking for a good scripting engine for the MS Windows platform. > > Java isn't a scripting language. .. ..Java supports scripting languages. <http://java.sun.com/developer/technicalArticles/J2SE/Desktop/ scripting/> Andrew T. > I am looking for a good scripting engine for the MS Windows platform. To supplement the others: if you are looking for something like C++ or C#, then Java could be the right choice. If you are looking for something like VBS, then the best the Java world can offer is probably Groovy and Jython (Python run in JVM). Java, Groovy and Jython are all free (as in free beer - free as in free speech is on the way). Arne > I am looking for a good scripting engine for the MS Windows platform. This would be in connection with your long-running "SeeScreen" project I guess. The aim of which, as I understand it, is to automate the use of any arbitrary application by the processing of screen images to pick out significant changes. Java is free to develop with and to deploy but I doubt Java will be well suited to your purposes. It isn't a scripting language for accessing screen data and controlling the cursor and key-entry for another arbitrary application.
