I am about to start developing a new internal web application for the company I work for. It will be a lightweight CRM app, focused on managing customer contacts info and related open issues, and integrating with various backend systems to get and update data.
I haven't done web applications for almost 2 years, my experience is both with JSP and ASP (not ASP.NET). I thought this could be a good opportunity to learn Ruby on Rails, which seems to be used for many web apps today. My manager is pushing to use JSP with Eclipse.
What is your experience with using Ruby for internal applications? Any pros / cons?
