Deployment of servlets & database

[Gert Grenander]

Hi,   I'm currently developing my first servlet-based web application, and I really like the concept of Java being platform independent language. But one thing that bugs me is that I feel that I got platform dependent when I took the decision of having a real database instead of XML to store the data. I'm currently using MS Access (yeah, I'm not perfect... but you use what you got... :) ) and my servlets access it via JDBC. But what if a customer wants to deploy the application on a non-Windows platform. (e.g. Unix) Isn't there an issue with it being developed in Bill's world?   It would be very interesting to hear from someone who has tackled this issue. (e.g. choice of database, that can be deployed with as little friction as possible on different platforms)   Best regards, Gert Grenander
