Java EE (Java Enterprise Edition) General Discussion

Hi friend,
I am new to JSP
i have java code and want to make it convert to the JSP code for using to send email.

/*
Some SMTP servers require a username and password authentication before you
can use their Server for Sending mail. This is most common with couple
of ISP's who provide SMTP Address to Send Mail. in my Application of JSP. ??

This Program gives any example on how to do SMTP Authentication
(User and Password verification)

This is a free source code and is provided as it is without any warranties and
it can be used in any your code for free.

/*
To use this program, change values for the following three constants,

SMTP_HOST_NAME -- Has your SMTP Host Name
SMTP_AUTH_USER -- Has your SMTP Authentication UserName
SMTP_AUTH_PWD -- Has your SMTP Authentication Password

Next change values for fields

emailMsgTxt -- Message Text for the Email
emailSubjectTxt -- Subject for email
emailFromAddress -- Email Address whose name will appears as "from" address

Next change value for "emailList".
This String array has List of all Email Addresses to Email Email needs to be sent to.


Next to run the program, execute it as follows,

SendMailUsingAuthentication authProg = new SendMailUsingAuthentication();
