I am starting a new application, it needs to use db such as access or
msde.  I know I can do this easily in c# or Java but my question is can
I distribute  a package as easy if it is created with java and say derby
db as I can with windows based.  It needs to be click to install and
thats it, no exceptions.  To date I have done this with vb and c++ with
access and have had excellent success.  I really want to make the
transistion to java world but worry it will make installations difficult
for our customers.

I am interested in both application based and even if it is easy to
distribute a tomcat/derby/web based application.
I will be installing mostly on windows, but maybe some day customers
will start asking for linux/unix.
Thanks for any advice
