Thanks for your reply,
What have you guessed is exactly right but i didn't get an error or even exception. After my eight attempt in addition there is no response.
Here i show you DesignationOperation.addDesignation()
public static void addDesignation(Designation desig,HttpServletRequest request){
String strquery="";
HttpSesson session = request.getSession();
DataSource ds = (DataSource) session.getAttribute("ds");
Connection con = null;
Statement st= null;
try
con = ds.getConnection();
st = con.createStatement();
strquery = " insert into desig values(" + desig.getId() " + ",'" + desig.getName() + "')";
st.executeUpdate(strquery);
}catch(SQLException sqle){System.out.println(sqle);}
could you guess any bugs in above coding. if there help please
