Hi,

I am trying to send html mail in GWT project through RPC call .
the RPC method is invoked successfully, but when the code gets to the
following line:

Transport transport = mailSession.getTransport("smtp");

I get
javax.mail.NoSuchProviderException: Unable to locate provider for
protocol: smtp

i have download javamail 1.4.5 and added the jars to the buildpath
(including smtp.jar ) but nothing helps.

could you please advice ?

* see below full code:
try{
final String from = "mym...@gmail.com";
final String password = "mypassword";
final String to = "maild...@gmail.com";
final String body = "<body> bla bla </body>";

String host = "smtp.gmail.com";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", password);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
Session mailSession = Session.getDefaultInstance(props,
null);
// mailSession.setDebug(true);
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("bla bla blu");
message.setFrom(new InternetAddress(from));
message.setContent(body, "text/html");
InternetAddress toAddress = new InternetAddress(to);
message.addRecipient(Message.RecipientType.TO,
toAddress);
Transport transport = mailSession.getTransport("smtp");
transport.connect(host, from, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (MessagingException e) {
e.printStackTrace();
}

Hi,

What do your web.xml and context.xml look like?

-> web.xml:

...

<context-param>
<param-name>MAIL-NAME</param-name>
<param-value>mail/GmailSmtpServer</param-value>
<description>The name of the mail Session used by sample
application.</description>
</context-param>

->

-> context.xml:

<Resource name="mail/GmailSmtpServer"
auth="Container"
type="javax.mail.Session"
mail.transport.protocol="smtp"
mail.smtp.host="smtp.gmail.com"
mail.smtp.port="465"
mail.smtp.auth="true"
mail.smtp.user="user...@gmail.com"
password="password"
mail.smtp.starttls.enable="true"

mail.smtp.socketFactory.class="javax.net.ssl.SSLSocketFactory"
mail.debug="true" />

->

Are you running hosted mode (no JNDI support ?) or have you deployed
the app to Tomcat and placed the jars in \lib (activation and mail)?

Cheers
Rob

Exception reading response (java.net.SocketException: Socket operation timed out: The API call remote_socket.Receive() took too long to respond and was cancelled.)
