Xstream error and what DB to use?

Hello,

I am writing an application and I am having a bit of a quandry, first off, what type of database should I be using to store the data? There will be potentially upwards of 1000 rows of data or so. My first thought was MySql, but then I thought about it and, unless im wrong, this will mean that anyone that wants to use the program must also goto mysql, download the database, then come back and run a setup to add the tables into mySql. This seems like alot of extra steps, so I though maybe flatfile, but then there is no security, and even though the data is not vital or needs to be kept private, there still will be the passwords for the people logging in.

So I did some research and found XStream. This seems like it could work, but for the life of me I cannot figure out how to get it installed into Netbeans correctly.

I went to the "2 minute tutorial" and figured I would try it, so i found THIS example. I put Xstream into a library (and Xpps into a library as well) then added them to my project, i copied and pasted the sample code into netbeans like so:

Xstreamtest

and it shows no errors but when i try to run it i get this:

Line 37 of Xstreamtest is this btw:

ShipOrder shipOrder1 = (ShipOrder) xstream.fromXML(shipOrderXml);

So my question(s) are this:
1: What should I be using to store data?
2: any idea what is wrong with the above?

Thank you for any help...
