You can send an email in JSP.

1. We can send mail via any JSP Engine (such as jswdk) that supports sun.net. SMTP packages in Sun specifications.
(Warning: Use the built-in internal sun specification package, which will affect your JSPProgram.)

The following scriptlet uses the smtpclient class to send emails to JSP files.

<% @ Page import = "sun.net. SMTP. smtpclient, java. Io. *" %>
<%
String from = "gseshadri@hotmail.com ";
String to = "govind@jguru.com, govi@bigfoot.com ";
Try {
Smtpclient client = new smtpclient ("mail. XXXXX. XXX ");
Client. From (from );
Client. To ();
Printstream message = client. startmessage ();
Message. println ("to:" + );
Message. println ("Subject: sending email from JSP! ");
Message. println ("This was sent from a JSP page! ");
Message. println ();
Message. println ("Cool beans! :-)");
Message. println ();
Message. println ("Govind seshadri ");
Message. println ("jguru.com ");
Message. println ();
Client. closeserver ();
}
Catch (ioexception e ){
System. Out. println ("error sending email:" + E );
}
%>

2. javamail is the official Java mail API. For details, refer to http://java.sun.com/products/javamail /. Although this API is richer or more complex than sun.net. SMTP. smtpclient, It is portable. Here, a new mailsender class is created, which contains the javamail API. As follows:

// MS _ prefix is for mailsender class variables
// STR prefix is for string
// Astr prefix is for array of strings
// Strbuf prefix is for stringbuffers, etc.
Public mailsender (
String strfrom, // sender
String [] astrto, // recipient (s)
String [] astrbcc, // BCC recipient (s), optional
String strsubject, // subject
Boolean debugging)
{
Ms_strfrom = strfrom; // who the message is from
Ms_astrto = astrto; // who (plural) the message is
Ms_debugging = debugging; // who (plural) the message is

// Set the host
Properties props = new properties ();
Props. Put ("mail. SMTP. Host", ms_strsmtphost );

// Create some properties and get the default session
Session session = session. getdefaultinstance (props, null );
Session. setdebug (ms_debugging );

Try {
// Create a message
Ms_msg = new mimemessage (session );

// Set the from
Internetaddress from = new internetaddress (strfrom );
Ms_msg.setfrom (from );

// Set the
Internetaddress [] address = new internetaddress [astrto. Length];
For (INT I = 0; I astrto. length; ++ I)
{
Address [I] = new internetaddress (astrto [I]);
}
Ms_msg.setrecipients (message. recipienttype. To, address );

// Set the BCC recipients
If (astrbcc! = NULL)
{
Address = new internetaddress [astrbcc. Length];
For (INT I = 0; I astrbcc. length; ++ I)
{
Eh. dbg ("astrbcc [" + I + "] is: '" + astrbcc [I] + "'");
Address [I] = new internetaddress (astrbcc [I]);
}
Ms_msg.setrecipients (message. recipienttype. BCC, address );
}

// Set the subject
Ms_msg.setsubject (strsubject );

// Set up the string buffer which will hold the message
Ms_strbufmsg = new stringbuffer ();

} Catch (messagingexception MEX ){
Mex. printstacktrace (system. Err );
} Catch (exception ex ){
Ex. printstacktrace (system. Err );
}
}

Public void ms_add (string strtext)
{
Ms_strbufmsg.append (strtext );
}

Public void ms_send ()
{
Try {
// Set the content as plain text
Ms_msg.setcontent (new string (ms_strbufmsg), "text/plain ");

// And away
Transport. Send (ms_msg );
} Catch (exception ex ){
System. Out. println ("caught exception in mailsender. ms_send:" + ex );
}
