Answer 1

here is my code...actually my program send email from SMS. i parser SMS to email format. My SMS part is working but when i combine it,i got error as above. I tried run without servlet (using command prompt) it working properly and i can send email.
public class EmailSMSServlet extends HttpServlet
CService srv;
int status;
LinkedList msgList;
     public void init(ServletConfig config) throws ServletException      {
     super.init(config);
     srv = new CService("com4", 9600);
     msgList = new LinkedList();
     srv.initialize();
     srv.setCacheDir(".\\");
public void doPost(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException
     PrintWriter writer = response.getWriter();
response.setContentType("text/html");
writer.println("<html>");
writer.println("<head>");
writer.println("<title>SMS TO EMAIL</title>");
writer.println("</head>");
writer.println("<body bgcolor=\"blue\">");
     writer.println("test");
          try
          status = srv.connect();
               if (status == CService.ERR_OK)
               srv.setOperationMode(CService.MODE_PDU);
if(srv.readMessages(msgList,CIncomingMessage.CLASS_ALL)==CService.ERR_OK)
          for (int i = 0; i < msgList.size(); i ++)
          CIncomingMessage msg =(CIncomingMessage)msgList.get(i);
          String s=msg.getText();
          String from1=msg.getOriginator()+"@mysite.bla.bla";
          writer.println(s);
          writer.println("<p>");
          writer.println(from1);
          writer.println("<p>");
// parser sms to email ...
String delim = "#";
StringTokenizer st= new StringTokenizer(s,delim);
String str[] = new String[st.countTokens()];     
int j=0;
while (st.hasMoreTokens())
     str[j++] = st.nextToken();
     writer.println("<p>");
     writer.println("Kepada:");
     writer.println(str[0]);
     for(int k = 0; k < str.length; k++)
writer.println(str[k]);
// Send mail using javamail.....
Properties props=new Properties();
props.put("mail.transport.default",blah");
props.put("mail.smtp.host","blah");
try{
Properties props=new Properties();
props.put("mail.transport.default","smtp");
props.put("mail.smtp.host","host");
Session mailSession=Session.getInstance(props,null);
Message mssg=new MimeMessage(mailSession);
mssg.setSubject(str[1]);
mssg.setContent(str[2],"text/plain");
Address to =new InternetAddress(str[0]);
mssg.setRecipient(Message.RecipientType.TO,to);
Address from=new InternetAddress(from1);
mssg.setFrom(from);
Transport.send(mssg);
     writer.println("Succes");
} catch (Throwable t) {
writer.println("<font color=\"red\">");
writer.println("ENCOUNTERED EXCEPTION: " + t);
writer.println("<pre>");
t.printStackTrace(writer);
writer.println("</pre>");
writer.println("</font>");
     srv.disconnect();
     else
     writer.println("Connection to mobile failed, error: " + status);
     catch (Exception e)
          e.printStackTrace();
     writer.println("<br><br>");
writer.println("</body>");
writer.println("</html>");
thanks
