ASP or JSP?

Fooknut asks: "I'm here, in the infant stages of development of a corporate website, and portal for my employer. I asked to build on JSP/servlets/EJB, so they setup a Win2k server with IIS 5 and JRun (allaire). Two weeks into the dev process they have a meeting with some managing "programmers" and the decision is made that JSP/Java was just a foolish thing to do, and that we should go with ASP. So here I am, chucking all of my hard work out of the window because someone "important" likes ASP better. Luckily I haven't written much code yet. These decisions are made by ASP lovers, people stuck in the MS rut, unwilling to try or hold a new skillset (I believe because they don't know how and don't want to know how to program anything else). Does it make business sense to put all your chips in the MS hat? Should a web dev co do one thing only, or should it embrace a variety of technology? So what are the advantages and disadvantages of JSP over ASP and vice-versa? Please don't post anti-MS comments, I really would like some serious comparisons."
