To use it, try like:

<%@page import="app.*"%>

<%

String SMTP = "smtp.domain.com";
      
      String imgRootPath = ""; //Reserved
      String RootPath = ""; //Reserved
      
      String adminSenderName = "<Sender>";
      String adminSenderEmail = "admin@domain.net";
      

String referfirstname = (request.getParameter("referfirstname")==null)?"":request.getParameter("referfirstname");
      String refersurname = (request.getParameter("refersurname")==null)?"":request.getParameter("refersurname");
      String referemail = (request.getParameter("referemail")==null)?"":request.getParameter("referemail");
      
      String friendfirstname1 = (request.getParameter("friendfirstname1")==null)?"":request.getParameter("friendfirstname1");
      String friendsurname1 = (request.getParameter("friendsurname1")==null)?"":request.getParameter("friendsurname1");
      String friendemail1 = (request.getParameter("friendemail1")==null)?"":request.getParameter("friendemail1");
      
if (!friendsurname1.equals("") && !friendemail1.equals("")) {
                  
                  try {
                        libmail_wc mail = new libmail_wc(adminSenderName, adminSenderEmail, friendfirstname1 +  " " + friendsurname1, friendemail1, SMTP, "<Subject to change>", RootPath, imgRootPath, l, "file", "No Value", localedmpath, para);
                        mail.start();                        
                  } catch (Exception e) {}
                  System.out.println("Sent 1");                        
            }
