Package com.web.servlet;

Import java.io.IOException;
Import Javax.mail.Message;
Import javax.mail.Session;
Import Javax.mail.Transport;
Import javax.mail.internet.InternetAddress;
Import Javax.mail.internet.MimeMessage;

Import Javax.naming.InitialContext;
Import javax.servlet.ServletException;

Import Javax.servlet.http.HttpServletRequest;

Import Javax.servlet.http.HttpServletResponse; /** * Use a content.xml configuration file to write a Web email */public class Sendmailservlet extends HttpServlet {public void doget (httpse Rvletrequest request, HttpServletResponse response) throws Servletexception, IOException {try {context Contex

			Transport.close ();
		Response.getwriter (). println ("Send ok!");
		catch (Exception e) {e.printstacktrace (Response.getwriter ()); } public void DoPost (HttpServletRequest request, httpservletresponse response) throws Servletexception, Ioexce
	ption {doget (request, response); } The resources defined in this elements may is referenced by the following elements in the Web application Deploymen T Descriptor (/web-inf/web.xml) of the Your WEB application; Important profile Context.xml, the file is placed under Web-inf Meta-inf, which is detailed below: < context> <resource name= "Mail/context" auth= "Container" type= "Javax.mail.Session" mail.smt P.host= "smtp.sina.com" mail.smtp.auth= "true" MAIL.TRANSPort.protocol= "SMTP"/> </Context>
