Matt - I thought I’d just point out that the IO class in my code is also part of the Jetty package and not standard Java.

Webrick is part of the standard library in 1.8.X ruby’s =)

Jason: your absolutely right. In Mark’s code there is a call to IO.copy copying an IinputStream to an OutputStream, which greatly reduces the amount of code in my example too, could get rid of an entire method.

Thats one of the great things about blogging, we can all learnsome new things. I’m not experienced in embedding Jetty, but it is definetly something I will keep in mind if I ever need a quick server in Java again… I’m sure it will happen sooner than later.

Mark: thanks for your posts… I didn’t think to mention that WEBrick is not an “official” package. It isn’t, though everywhere I’ve used Ruby it has been there, like you mentioned. My primary dev box is XP/Eclipse/Tomcat/MySQL, so I didn’t have any extra software to install, and frankly I doubt anyone who does this for a living is without a servlet container handy. And if I were doing Ruby constantly, I would probably have Apache + FastCGI setup and ready to go, so that evens itself out.

You do still have the extra configuration of the Web.xml file, though in my case that is usually handled by my IDE.

It’s swings and roundabouts really. I don’t see how the comparison acutally works. Everyone uses libraries to some degree so the code amount and savings are going to be different anyway.

Matt, having a few issues getting the trackback working, but I posted a version using an embedded Jetty webserver over on my blog…

filenames = Dir.glob(”*.{xml,XML}”).sort

files = Array.new
for x in 0…filenames.size
puts “Adding file: #{filenames[x]}”
files[x] = File.read(filenames[x])
end

the above can be reduced to (not tested):

files = Dir.glob(”*.{xml,XML}”).sort.collect do |filename|
puts “Adding file: #{filename}”
File.read(filename)
end

Lets just say you had jetty on the classpath, had a blanket ‘throws Exception’, and used FQN class references everywhere, how much smaller could you get the java code?

Part of me also wonders about the scenario where webrick ISN’T installed on the system, what would you need to do in order to get your ruby application web-enabled? Configuration for Apache? IIS?

(To be honest, I’m not sure if there ever would be a scenario where webrick isn’t available, I just apt-get’d ruby on my Unbuntu machine and it was there so maybe its an “official” library?)
