Roman, I dont think autoboxing will do the trick here. If the int is
NULL in the database, getInt() will return a zero, and autoboxing would
result in a Integer.valueOf(0) and not the desired null. Anyway, I think
autoboxing is evil and should be avoided in most situations.

getObject(int) is a good option. However, an even better idea would be
to use some framework to abstract JDBC code, like Apache DBUtils,
Hibernate or JPA.
