I would go with C#. There are lot's of people who say that you are subject to Microsoft's directing of the language, but if you go with Java, you are subject to Sun/OS direction just the same. C# is a great language and ASP.Net is great for the Web. It's not popular to advocate a Microsoft product here but I'm very happy with C# and ASP.Net. Your goals will be the ultimate factor in your decision though.

"if you go with Java, you are subject to Sun/OS direction"
Not as much, now that Java is open sourced.
