I have 4 years of .NET development experience (3 years of VB6 and ASP experience before that) and I have the opportunity to change from my current position as a .NET developer to a position that will be on a Java (J2EE) platform. I have Microsoft certifications and have really been .NET (C#) focused for years (with minimal experience in Java). I am looking for opinions on if this sounds like a good career move (to expand my skill set) — or a bad career move (to risk falling out of practice in .NET — in which most of my career skills have been based). I realize my potential new employer is taking a bit of risk by hiring me since I have little Java experience (but they feel I am good OO developer and I could pick up Java quickly based upon my compentency in C#). I do not know of anyone who is really good in BOTH platforms… so I have reservations about switching platforms at this point in my career. Any thought/opionions?
