hi everybody,
i spent my whole afternoon with a stupid numberformat
exception.
at last i gave up,and decided to bring
here.
can someone help me with this please, or I will
get crazy.
i am using tomcat 4 on windows 2000.
this jsp file takes a request parameter no, which is
an integer.
but it seems that it can't receive or read this
parameter correctly.
i call this jsp from my from browser as
:
but i always have the same exception (
numberformat exception)
below is my code:
<%@ page language="java" contentType="text/html;
charset=BIG5" %>
<%@ page import="java.sql.*,java.util.*,org.gjt.mm.mysql.*" %> <HTML><HEAD><TITLE>NEWS</TITLE> <META content="text/html; charset=big5" http-equiv=Content-Type> </HEAD> <BODY bgColor=pink leftMargin=0 text=#000000 topMargin=0 marginheight='0' marginwidth='0'><BR> <%! Connection conn; String ndate,subject,news; int no; Statement stmt; ResultSet rs; String sql; %> <%
Class.forName("org.gjt.mm.mysql.Driver");
if ((request.getParameter("no")!=null)&& (request.getParameter("no")!="")){ try { conn = DriverManager.getConnection("jdbc:mysql:///yilmaz"); no=Integer.parseInt(request.getParameter("no")); sql="select ndate,subject,news from new"+no; stmt = conn.createStatement (sql); rs = stmt.executeQuery
();
while (rs.next() ) { ndate=rs.getString(1); out.println(ndate); subject=rs.getString(2); out.println(subject); news=rs.getString(3); out.println(news); } } catch
(SQLException e) {
out.println("SQLException caught "+ e.getMessage()); e.printStackTrace(); } catch (NumberFormatException nfe) { out.println("NumberFormatException caught "+nfe.getMessage()); } finally { rs.close(); stmt.close(); conn.close(); } } %> ****************************************************
the whole other followings are normal html
code
****************************************************
when i run my JSP it throws :
org.apache.jasper.JasperException: Unable to compile
class for JSP
... root cause :
java.lang.NumberFormatException: mysql
at java.lang.Integer.parseInt(Integer.java:414) at java.lang.Integer.parseInt(Integer.java:463) ... ********************************
