I have been assigned a task to develop an online store.I am facing a problem at the time of insertion of records into SQL Database. I am using Type4 driver. The name of the DNS is SQL. here is my servlet code

protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        PrintWriter out= response.getWriter();
        String Fname= request.getParameter("txtfname");
        String Lname= request.getParameter("txtlname");
        String Uname=request.getParameter("txtuname");
        String Pass=request.getParameter("txtpass");
        String Email=request.getParameter("txtemail");
        String Gender=request.getParameter("group1");
        String Add=request.getParameter("txtadd");
        //out.println(""+Fname+Lname+Uname+Pass+Email+Gender+Add);
        Connection con= null;
        try
        {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        }
        catch(Exception e)
        {
            out.println("Class not found");
        }
        try
        {
            con=DriverManager.getConnection("jdbc:odbc:SQL","sa","mith1234");
        }
        catch(Exception e)
        {
            out.println("Connection not found");
        }
        try
        {
            String insert="insert into sign_up values(?,?,?,?,?,?,?)";
            PreparedStatement ps= con.prepareStatement(insert);
            ps.setString(1,Fname);
            ps.setString(2,Lname);
            ps.setString(3,Uname);
            ps.setString(4,Pass);
            ps.setString(5,Email);
            ps.setString(6,Gender);
            ps.setString(7,Add);
            int rt= ps.executeUpdate();
            if(rt==0)
            {
                out.println("Data is not inserted");
            }
        }
        catch(Exception e)
        {
            out.println("Data Cannot be inserted");
        }
        
    }

Since there is no problem in retrieving values from the JSP page and no problem with the request.getParameter. The only problem is at the last try catch block. I am getting an exception "Data Cannot be inserted". Do help me in fixing this insertion problem...

What database are you using? If it is not Access then use the JDBC Driver meant for that DB, not the JDBC-ODBC bridge, and if you are using Access, then use a different db.

And, if you want to know what the problem is, then don't hide it behind your own meaningless error statement. Add a printstacktrace call to that catch block.

The problem is fixed now... thanks for the help anyways :)
