Just wondering if anyone has any experience on how to "deploy" a JRuby application to another server?
That is I am developing a jRuby Application on Windows, and I want to eventually deploy it to a host of Linux/Unix Servers. So specifically -
How easy is it too deploy or just a nightmare?
Would I have to recompile all the "gems" (dependencies) or try figure out a way to bundle them as a deploy package? Or would I have to configure jRuby individually per server as I did on my Dev Machine (Windows Box)
PS. The App is made up of Client/Server.
Thanks
Consider using trinidad or warbler; it wraps up most of these issues.

I'm looking on ways to deploy a ruby on rails 4 app built on windows 7 box. I'm looking to use Heroku at the moment.
Can you please provide any pointers regarding heroku or any other easier and cheaper deployment options available out there..
Any issues That I may face due to the difference in OS in the dev environment (windows) and the deployment environment (linux on heroku)?
This is my first professional app, so any pointers will be helpful for now and also for future applications that I may work on.
Also what is the more preferred OS for ruby on rails development ?
Thanks in Advance!
You probably won't face any issues with deployment on Heroku. Heroku is the easiest option out there (albeit one of the priciest once you're off the free tier)
What's more likely to happen on Windows is that you'll find it hard to build certain gems for development, and cutting edge releases will probably not work well.
Much better to pick up a Linux distro for this.
You can also check out bluemix , which is also free for small projects. I know Heroku is not particularly windows friendly, not sure if bluemix is any better in that reguard, but it is extremely easy to deploy to.
Heroku has set of tools called heroku toolbelt, that makes easy to deploy apps to heroku. you can download heroku tool belt for windows from here
Generally you should be able to port any rails app you develop in windows to Linux/Mac, how ever since the ruby/rails community is largely built around Linux/Mac, responses/options to your issues regarding the rails apps will be low. and there are some gems which doesn't work on windows at all. So its best to move to either Mac/Linux if you are planing to continue on rails.
Once you come to Linux/mac world there are lots of providers much cheaper than heroku like DigitelOcean, however heroku would be the easiest for a beginner I believe.

One strategy you could try is to do the following:
Set up a VirtualBox or VMWare VM running Linux (Ubuntu would be a good candidate if you are not used to Linux).
Get your project into the VM and get the bundle install and everything working in Linux, you will probably find you need to make some changes in your Gemfile if you have anything windows specific there.
Install the Heroku tool-belt on the Linux VM and install to Heroku from there.
Taking the Windows / Linux transition pain on your local machine will make it much easier than Windows direct to Heroku.
My next work project is going to be using the Meteor framework. Our team recently got licensed to use WebStorm IDE, which has been our favorite up until this point. so we were planning on continuing the project with it.
That is, until it was time to install it. Then we found out that the Windows version of Meteor is only partially finished, and all of our development PC's are windows based.
So we were considering as a work-around for this, we may use Cloud9 as our development IDE, as it supports Meteor. The sharing functions may help our team productivity a bit as well.
But this has some problems...
First, we just invested in WebStorm, so we would ideally like to use it as our primary IDE. But I do not know how we would be able to work with WebStorm if we can not run an up to date version of Meteor on our windows systems?
Second, I'm not sure if it's even possible to use Cloud9 as the development IDE, but then move the C9 project over to our Ubuntu server for hosting when it is time to go live?
Third, even if we could deploy to our Ubuntu server after C9, we plan on many updates to our live application after deployment. I'm not sure if there would be issues with this if our development is on C9 and deployment on a completely different server.
So I'm wondering if anyone has a potential solution for these issues? Is there any way for us to work with Meteor on our live Ubuntu server, or Cloud9, from WebStorm on our Windows systems? Or any way we could integrate Cloud9 and WebStorm together for the best of both worlds? Or any way we could use a Linux emulator or something to allow us to use Meteor on our local windows system, without making it difficult for multiple developers to work on the project at the same time?
Thanks in advance!
The Windows port of Meteor actually is working quite well; the only major issue is that mobile development doesn't work. That is going to be fixed in Meteor 1.1 anyway, whose primary goal is to get Windows support up to that of Linux and Mac OS X.
As the user who initially pushed for Webstorm to add Meteor support back in October 2012, I'd recommend starting with Webstorm and Meteor on Windows right away, unless you need mobile development. In that case, you need native *nix machine (an Ubuntu VM on Windows won't be able to run the Android emulator, for example).
WebStorm also supports server-side Meteor debugging, and they're pretty responsive when it comes to fixing bugs you report on YouTrack. See for example https://youtrack.jetbrains.com/issue/WEB-13490
With Cloud9, you cannot currently SSH into a workspace you have, so a hybrid Webstorm/Cloud9 situation might not be doable at this point.
As for deploying your stuff from Cloud9, that is very doable. There's some documentation here about that: https://docs.c9.io/v1.0/docs/deploying-via-the-command-line
I need to scrap websites with python (selenium) so i need to install Firefox or chrome or ... .
with openshift servers how could i install Firefox in an OpenShift DIY cartridge?
Thanks a lot.
Since there is no xwindows system installed on OpenShift, I dont' think that firefox will be able to either 1.) be installed or 2.) run on the platform.
You would be better off using something like the nokogiri gem with Ruby, or a python/php library for scraping web content. You might also consider doing the scraping on your own computer, then upload the information that is needed by your website if you HAVE to go the firefox/chrome route.
There are instructions for running Selenium tests in Firefox on a headless server on the OpenShift blog.

Can the code developed and running in Websphere application server v5.1 run in Websphere application server v6.0/6.1/7.0 without any problems?
My scenario:
Originally, the application developed using Java 1.4 and WAS v5.1. As part of change request, we are going to do some changes in that application.
Currently, in my development environment i have RSA(Rational Software Architect) 7.5. It complaint with only WAS v6.0/6.1/7.0. So i can work with one of these WAS version.
Which version i can choose to work for development WAS v6.0/6.1/7.0?
But finally the developed/changed code in WAS6.0/6.1/7.5 will be deployed in WAS v5.1(PRODUCTION) only. I am worried about whether code will run properly or not.
Will i get any complaint problem in this scenario?
Thanks in advance.
The most important is not to change your compiler settings from 1.4 to the RSA 7.5 default which I believe is 1.5.
In case you compile your source code with higher version of Java and deploy it in a Container which runs on a lower version you are going to have trouble.
Generally it is safe to run and test your legacy app on a higher WAS version but keep your eyes on the compiler settings as I mentioned.
I want to make a development server for Ruby. (I have done this for IIS and a LAMP set up, but am by no means proficient at it.) What will I need besides the actual server (which I already have)? And also any security issues? I know I could dev locally on my machine, but don't want to do that.
First off when doing ruby development the first thing to know is that it works best in a unix like environment, so mac os x, linux, solaris, bsd, etc...
Ruby libraries are distributed and packaged as gems. So you'll want to install ruby and install rubygems. Then from there on you use the gem command for installing ruby libraries.
I'm going to assume you're talking about doing web development with either ruby on rails 2.x or Merb 1.x. The two frameworks are merging in the next release and it'll be called Rails 3.0. So the answer here works for either one. I'm going to say Rails, but i mean Rails/Merb.
Rails development is done locally on your machine. So you'll need to install ruby and all the libraries you need locally. I know many people who use Windows end up using virtualization and running a linux environment for rails within their desktop windows box.
In development most people use an application server, Mongrel. In production the current standard is to use Apache 2 and Passenger.
With rails you're going to want to use source control. Most people today use git in the rails community, but it's possible to use subversion, perforce, or many other SCM's. To get your application from your source control to your staging and production systems, the rails community created an application called Capistrano. It handles deployments. You setup your server information, ssh keys, define access, and then you can release your application with a single command.

It's a pretty good system. Back several years ago now when i was working on odeo.com we had people using windows, linux, and mac's all for development with production deploys to debian linux. It wasn't intentional that our application be cross platform, it just worked out that way because we had people who wanted to add to it, including designers and biz types, who were on windows.
