Problem with exception

[Telmo S�]

Hello all!
I'm trying a JSP that instantiates a BEAN.
The BEAN performs a DB query and returns a ResultSet object which i wanted
to use in the JSP.
The problem is that i get
500 Internal Server Error

com.livesoftware.jsp.JSPServlet:

java.lang.NullPointerException

and i'm not understanding why.

This is the small code.
 <<telmo.jsp>>  <<process.java>>
Thank you for any help!

        Telmo

telmo.jsp

process.java
