Vamos criar a classe de entidade que ter\u00e1 as propriedades para envio do email:<\/p>\n

\r\n\r\npackage br.com.feltex.email;\r\n\r\nimport java.io.Serializable;\r\n\r\npublic class Email implements Serializable {\r\n\t\r\n\tprivate static final long serialVersionUID = 8928827540810848202L;\r\n\r\n\tprivate String para;\r\n\t\r\n\tprivate String corpo;\r\n\t\r\n\tprivate String de;\r\n\r\n\tprivate String titulo;\r\n\r\n\tprivate String senha;\r\n\t\r\n\tpublic String getCorpo() {\r\n\t\treturn corpo;\r\n\t}\r\n\t\r\n\tpublic String getDe() {\r\n\t\treturn de;\r\n\t}\r\n\r\n\tpublic String getPara() {\r\n\t\treturn para;\r\n\t}\r\n\r\n\tpublic String getSenha() {\r\n\t\treturn senha;\r\n\t}\r\n\r\n\tpublic String getTitulo() {\r\n\t\treturn titulo;\r\n\t}\r\n\r\n\tpublic void setCorpo(String corpo) {\r\n\t\tthis.corpo = corpo;\r\n\t}\r\n\r\n\tpublic void setDe(String de) {\r\n\t\tthis.de = de;\r\n\t}\r\n\r\n\tpublic void setPara(String para) {\r\n\t\tthis.para = para;\r\n\t}\r\n\r\n\tpublic void setSenha(String senha) {\r\n\t\tthis.senha = senha;\r\n\t}\r\n\r\n\tpublic void setTitulo(String titulo) {\r\n\t\tthis.titulo = titulo;\r\n\t}\r\n\r\n\tpublic String toString() {\r\n\t\treturn \"Email [para=\" + para + \", corpo=\" + corpo + \", de=\" + de\r\n\t\t\t\t+ \", titulo=\" + titulo + \", senha=\" + senha + \"]\";\r\n\t}\t\t\r\n}\r\n<\/pre>\n
 Abaixo temos a classe Acesso que \u00e9 respons\u00e1vel por criar um objeto do tipo PasswordAuthentication d\u00e1 um suporte de dados que \u00e9 usado pelo autenticador em servidores. \u00c9 simplesmente um reposit\u00f3rio para um nome de usu\u00e1rio e uma senha.<\/p>\n
\r\npackage br.com.feltex.email;\r\n\r\nimport javax.mail.Authenticator;\r\nimport javax.mail.PasswordAuthentication;\r\n\r\npublic class Acesso extends Authenticator {\r\n\r\n\tprivate String usuario = \"\";\r\n\tprivate String senha = \"\";\r\n\r\n\tpublic Acesso() {}\r\n\t\r\n\tpublic Acesso(String usuario, String senha) {\r\n\t\tthis.usuario = usuario;\r\n\t\tthis.senha = senha;\r\n\t}\r\n\t\r\n\tprotected PasswordAuthentication getPasswordAuthentication() {\r\n\t\treturn new PasswordAuthentication(usuario, senha);\r\n\t}\r\n\r\n\tpublic String getSenha() {\r\n\t\treturn senha;\r\n\t}\r\n\tpublic String getUsuario() {\r\n\t\treturn usuario;\r\n\t}\r\n}\r\n<\/pre>\n
Abaixo temos a classe que envia o e-mail propriamente dito.<\/p>\n
\r\n\r\npackage br.com.feltex.email;\r\n\r\nimport java.util.Properties;\r\n\r\nimport javax.mail.Message;\r\nimport javax.mail.Session;\r\nimport javax.mail.Transport;\r\nimport javax.mail.internet.InternetAddress;\r\nimport javax.mail.internet.MimeMessage;\r\n\r\npublic class EnviaEmail {\r\n\r\n\tpublic void enviar(Email email) throws Exception {\r\n\t\tSystem.out.println(\"Inicio do programa\");\r\n\r\n\t\t\/\/Configura\u00e7\u00e3o para envio de E-mail via GMail\t\t\r\n\t\tProperties props = new Properties();\r\n\t\tprops.setProperty(\"mail.smtp.host\", \"smtp.gmail.com\");\r\n\t\tprops.setProperty(\"mail.smtp.socketFactory.class\",\r\n\t\t\t\t\"javax.net.ssl.SSLSocketFactory\");\r\n\t\tprops.setProperty(\"mail.smtp.socketFactory.fallback\", \"false\");\r\n\t\tprops.setProperty(\"mail.smtp.port\", \"465\");\r\n\t\tprops.setProperty(\"mail.smtp.socketFactory.port\", \"465\");\r\n\t\tprops.put(\"mail.smtp.auth\", \"true\");\r\n\t\tprops.put(\"mail.debug\", \"true\");\r\n\t\tprops.put(\"mail.store.protocol\", \"pop3\");\r\n\t\tprops.put(\"mail.transport.protocol\", \"smtp\");\r\n\r\n\t\tSession session = Session.getInstance(props, new Acesso(email.getDe(),\r\n\t\t\t\temail.getSenha()));\r\n\r\n\t\tsession.setDebug(true);\r\n\r\n\t\tMessage message = new MimeMessage(session);\r\n\t\tmessage.setFrom(new InternetAddress(email.getDe()));\r\n\t\tmessage.setRecipients(Message.RecipientType.TO,\r\n\t\t\t\tInternetAddress.parse(email.getPara()));\r\n\t\tmessage.setSubject(email.getTitulo());\r\n\t\tmessage.setText(email.getCorpo());\r\n\r\n\t\tTransport.send(message);\r\n\t\tSystem.out.println(\"Conclu\u00eddo\");\r\n\t}\r\n}\r\n<\/pre>\n
 Por fim temos o servlet que recebe os dados digitados pelo usu\u00e1rio e se encarrega de criar as inst\u00e2ncias das classes necess\u00e1rias para realizar o envio do e-mail.<\/p>\n
\r\npackage br.com.feltex.email;\r\n\r\nimport java.io.IOException;\r\nimport java.io.PrintWriter;\r\n\r\nimport javax.servlet.ServletException;\r\nimport javax.servlet.annotation.WebServlet;\r\nimport javax.servlet.http.HttpServlet;\r\nimport javax.servlet.http.HttpServletRequest;\r\nimport javax.servlet.http.HttpServletResponse;\r\n\r\n\/**\r\n * Servlet implementation class EmailServlet\r\n *\/\r\n@WebServlet(\"\/EmailServlet\")\r\npublic class EmailServlet extends HttpServlet {\r\n\tprivate static final long serialVersionUID = 1L;\r\n\t\r\n\tprotected void doGet(HttpServletRequest request,\r\n\t\t\tHttpServletResponse response) throws ServletException, IOException {\r\n\t\tdoPost(request, response);\r\n\t}\r\n\r\n\t\r\n\tprotected void doPost(HttpServletRequest request,\r\n\t\t\tHttpServletResponse response) throws ServletException, IOException {\r\n\r\n\t\tPrintWriter out = response.getWriter();\r\n\t\ttry {\r\n\t\t\tEmail e = new Email();\r\n\t\t\te.setDe(request.getParameter(\"txtDe\"));\r\n\t\t\te.setPara(request.getParameter(\"txtPara\"));\r\n\t\t\te.setSenha(request.getParameter(\"txtSenha\"));\r\n\t\t\te.setTitulo(request.getParameter(\"txtTitulo\"));\r\n\t\t\te.setCorpo(request.getParameter(\"txtCorpo\"));\r\n\r\n\t\t\tEnviaEmail envio = new EnviaEmail();\r\n\t\t\tenvio.enviar(e);\r\n\t\t\t\r\n\t\t\tout.append(\"

Erro no envio da mensagem! <\/H1>\");\t\t\t\r\n\t\t\tout.append(e.getMessage());\r\n\t\t}\r\n\t}\r\n}\r\n<\/pre>\n
 Teremos a p\u00e1gina de entrada dos sistema com os campos que comp\u00f5em um email. Ela deve ser nomeada como index.jsp<\/p>\n
