Well, you wouldn't. If "pst" is a PreparedStatement then its setString() method requires a String as the second parameter. So asking how to pass an ArrayList there doesn't make any sense. You should review your requirements to find out where that String is supposed to come from.
And just another piece of advice: if you are still working on basic Java or JDBC programming, then a servlet is going to be a very inconvenient test environment. Do your training and practicing in a plain old Java application. Then after you have working code, take that code and insert it into your servlet.
