i'm calling inserstudent.jsp file in action of form addstudent.jsp want insert data in database.

my database table's structure below:

id|name|rollnumber|phonenumber|studyprogram|status

below code inserstudent.jsp

<%@page contenttype="text/html" pageencoding="utf-8"%> <%@ page import="java.sql.*" %> <!doctype html> <html>    <body>      <%      string nam=request.getparameter("stuname");        string roll=request.getparameter("sturoll");        string phone=request.getparameter("stuphone");        string prog=request.getparameter("stuprogram");        string stats=request.getparameter("stustatus"); class.forname("sun.jdbc.odbc.jdbcodbcdriver"); string url =  "jdbc:odbc:stdprojectdatadsn"; connection c = drivermanager.getconnection(url); statement statement = c.createstatement() ; string sql = "insert students (id, name, rollnumber, phonenumber, studyprogram, status )"; sql += "values ( '"+ nam +"','"+ nam +"','"+ roll +"','"+ phone +"','"+ prog +"',"+ stats +" )"; statement.execute ( sql ); c.close(); response.sendredirect("manageallstudent.jsp");     %>  </body> </html>

this results in following exception:

http status 500

what missing or doing wrong? in showallstudent.jsp page shows me data database use same script.

you shouldn't write java code in jsp (read faq - how avoid java code in jsp). must have add servlet perform database operations.

apart have learn how jdbc api works , @balusc commented code victim of sql injection vulnerability. avoid sql injection, use prepreadstatement (parameterized query).

connection cn=null; preparedstatement ps=null;  class.forname("sun.jdbc.odbc.jdbcodbcdriver"); string url =  "jdbc:odbc:stdprojectdatadsn"; connection c = drivermanager.getconnection(url);  try{   string sql="insert students (id,name,rollnumber,phonenumber,studyprogram,status)                 values (?,?,?,?,?,?)";   ps=cn.preparestatement(sql);   ps.setint(1,10);   ps.setstring(2,nam);   ...   ps.executeupdate() }catch(sqlexception ex){  }finally{   if(ps!=null){      try { ps.close(); } catch(exception ex) {}   }   if(cn!=null){      try { cn.close(); } catch(exception ex) {}   } }

ps: in case column id autogenerate number not include in column set.

 string sql="insert students (name,rollnumber,phonenumber,studyprogram,status)                     values (?,?,?,?,?)";

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
