Calling Function on JSP page

Question

Hi all
can someone please tell what am I doing wrong here? I'm trying to call Function on a JSP page
CallableStatement cs = connection.prepareCall("{? = call pa_dump_xml.fn_user_diary(?)}");
ResultSet rs = cs.executeQuery();
while (rs.next()) {     
%>
    <input type="text" name="app1" id="textfields1" size="" value="<% out.println(rs.getInt(11));%>" readonly="readonly"/>
<%
rs.close();
%>... And I keep getting this error
root cause
javax.servlet.ServletException: java.sql.SQLException: Missing IN or OUT parameter at index:: 1Thanks

Thanks for your reply, this is my code ;
CallableStatement cs = connection.prepareCall("{? = call pa_dump_xml.fn_user_diary(?)}");
proc.registerOutParameter(1, Types.INTEGER);
ResultSet rs = cs.executeQuery();          
while (rs.next()) {     
%>
    <input type="text" name="app1" id="textfields1" size="" value="<% out.println(rs.getInt(1));%>" readonly="readonly"/>
......And the error I'm getting is
java.lang.NullPointerException It's a JSP page as an index page where I need to show Data in some textfields on load of page. I'm sure there is a better way of doing this but I can not think how to go about it.
Thanks
