Problem in Mail Attachemnt using JSP

[R SundaraPandian]

Hi,
I am gettting strange problem.Can some one help me..Please.
When I 'm suing the below code for sending mail and attachment,
I am using this code insidea component which will send mail.
To use that bean I ma using Usebean tag and using the bean
with session scope.
I could able to send the attachement.
Even after I send the mail,if i try to send another mail without
attachement,this program takes the same attachment for the next
mail,whic I intend to send with out attachment Why..
But,after attching and Transport send I ma making the file descriptor
and file Handler to point a null.
But I couldn't able to get the solution.

public String  SendMail(String hostid,String from,String to,String subject,String body,String attach)
throws SQLException
{
String res="";
System.out.println("Inside SemnMail Program---");
Vector toname = new Vector();
Vector sendname = new Vector();
boolean sessionDebug=false;
   Properties props = System.getProperties();
   props.put("mail.host",hostid);
props.put("mail.transport.protocol","smtp");
Session mailSession = Session.getDefaultInstance(props,null);
   mailSession.setDebug(sessionDebug);
   try
   {
   Message msg=new MimeMessage(mailSession);
   msg.setFrom(new InternetAddress(from));
   StringTokenizer token = new StringTokenizer(to,",");
while(token.hasMoreTokens()){
    toname.addElement(token.nextToken());
        }
        for(int i=0;i<toname.size();i++) {
       //InternetAddress[] address = {new InternetAddress(to)};
       System.out.println("to name --------->"+toname.elementAt(i));
       String to_name = toname.elementAt(i).toString();
       InternetAddress[] address = {new InternetAddress(toname.elementAt(i).toString())};
       msg.setRecipients(Message.RecipientType.TO,address);
       if ( !subject.equals("") )
       {
       msg.setSubject(subject);
}
       msg.setSentDate(new java.util.Date());
       MimeBodyPart mbp1 = new MimeBodyPart();
       mbp1.setText(body);
       Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
System.out.println("Attachment-->"+attach);
MimeBodyPart mbp2 = new MimeBodyPart();
if ( !attach.equals("") )
{
System.out.println("Inside Attachemnt Adding Part");
FileDataSource fds=new FileDataSource(attach);
mbp2.setDataHandler(new DataHandler(fds));
String fName="";
StringTokenizer file = new StringTokenizer(attach,"\\");
while(file.hasMoreTokens()){
    fName=file.nextToken();
        }
System.out.println("After Extracting--->"+fName);
mbp2.setFileName(fName);
mp.addBodyPart(mbp2);
}
msg.setContent(mp);
    Transport.send(msg);
    FileDataSource fds=new FileDataSource("");
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName("");
    sendname.addElement(toname.elementAt(i));

}
if(sendname.size() == 0){
    System.out.println("Your mail has not sent to " + to);
    res="Not Success";
}
else{
   System.out.println("Your mail has been  sent to ");
   for(int j=0;j<sendname.size();j++) {
      System.out.println(sendname.elementAt(j));
   }
   res="Success";
}
   }
   catch(MessagingException mex){
      mex.printStackTrace();
   }
   return res;
}//For Send Mail
