Actually I am working on Dyna Action Form in struts and need to insert data into database following is code which I have been using

ACTION CLASS

public class DynaAction extends Action {

    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response){


      DynaActionForm  obj=(DynaActionForm) form;
      System.out.println(obj.get("userName"));
      System.out.println(obj.get("passWord"));

      Connection con=null;
      try {
        Class.forName("com.mysql.jdbc.Driver");
        con=DriverManager.getConnection("jdbc:mysql://localhost:3306/struts","root","root");
        String vsql="Insert into login values(?,?)";
        PreparedStatement pstmt=con.prepareStatement(vsql); 
        pstmt.setString(1,(String)obj.get("userName"));
        pstmt.setString(1,(String)obj.get("passWord"));

        if(pstmt.executeUpdate()==1)
            return mapping.findForward("success");

      } catch (Exception e) {
          System.out.println("Some Exception has Occured");
        // TODO: handle exception
      }

        return mapping.findForward("fails");

    }

}
