Really a strange problem, isn't it? For your reference, please try the following: First, try "http://localhost:8080/newscont.jsp?no=123"; Second, check to ensure that the page who calls "newscount.jsp" correctly uses the METHOD of "POST" or "GET" (with "GET" as default); At last, I recommend such a coding pattern as follows: int no = 0; try { no = Integer.parseInt(request.getParameter("no")); } catch (Exception e) { System.err.println("Exception: " + e); } // now the integer variable of "no" can be used carefree Happy coding!

What can be wrong ? according to your advices i changed my code as follows : <% Class.forName("org.gjt.mm.mysql.Driver"); String no=request.getParameter("no"); /* i also tried with int no=request.getParameter("no"/no) didn't work either */ no=no.trim(); if ((no!=null) && (no.length()!=0)){ out.println("the value of no : "+ no); try { conn = DriverManager.getConnection("jdbc:mysql:///yilmaz"); String sql="select ndate,subject,news from new where no="+no; stmt = conn.createStatement (sql); out.println("sql string is :" + sql); rs = stmt.executeQuery (); .....it goes on... still i am having this error : Any idea ???
