使用JSP开发WebMail系统

String username=request.getParameter("login");String password=request.getParameter("password");Session session2=Session.getInstance(System.getProperties() ,null);Store store=session2.getStore("pop3");

try{ store.connect(host,username+"%nyist.net", password);}catch(javax.mail.AuthenticationFailedException e){content="用户名与密码不匹配";}

store.connect("nyist.net",-1,request.getParameter("username")+"%nyist.net",request.getParameter("password"));

Folder folder = store.getFolder("INBOX");Folder.open (Folder.READ_WRITE);Message message[]=folder.getMessages();FetchProfile fp=new FetchProfile();fp.add(FetchProfile.Item.ENVELOPE);fp.add(FetchProfile.Item.FLAGS);fp.add("X-Mailer");folder.fetch(message,fp);

String contentbody="";Object o=message[j].getContent();

if (message[j].isMimeType("text/plain")) { contentbody=(String)+"</td>"; StringBuffer  buf=new  StringBuffer(contentbody.length()+6); char  ch=' '; for(int  p=0;p<contentbody.length();p++)//若遇到换行就转为<br> {ch=contentbody.charAt(p);  if(ch=='\n')buf.append("<br>");  else  buf.append(ch); } contentbody=buf.toString();}
