List list=new ArrayList();
response.setContentType("text/html");
PrintWriter out = response.getWriter();
System.out.println("Oracle Connect Example.");
Connection conn = null;
String url = "
jdbc
racle:thin:@localhost:1521:xe";
String driver = "oracle.jdbc.driver.OracleDriver";
String userName = "system";
String password = "mint";
Statement st;
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url,userName,password);
System.out.println("Connected to the database");
String ndate = request.getParameter("date");
String eid = request.getParameter("empid");
String strar[] = ndate.split("/");
String cdate = strar[0]+"/" + strar[1]+"/"+ strar[2];
if(eid==null||eid=="Enter Your Employee ID"){response.sendRedirect("viewnotes.jsp");}
String query = "select * from CNMS_NOTES where emp_id='"+eid+"' and note_date='"+cdate+"'";
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery(query);
while(rs.next()){
list.add(rs.getString("note_date"));
list.add(rs.getString("title"));
list.add(rs.getString("description"));
out.print(rs.getString(5));
}
}
catch(Exception e){out.print(e);}
request.setAttribute("description",list);
RequestDispatcher rd = request.getRequestDispatcher("/displaynotes.jsp");
