Sending Email with java

Hi,
I had to send an email using java, I wrote a java class that helps you shooting emails.
I am sharing the source code so that it can be used by others too..
It doesn't support email attachments as it was not the requirement in my case but it can be done too..
Thanks



Things to download
1) java mail API

I used: mailapi.jar



2) My written java Class

package com.breeze.utils;

Use this utility to send text emails.
You can use database to store templates, depends on your needs and requirements. This is a simple code that lets you know how to use mail API.

I have taken a number of values from PROPERTY file to keep the things dynamic.

#----email properties
mail.smtp.host=smtp.company.biz
mail.smtp.port=25
mail.smtp.socketFactory.port=25
mail.smtp.username=username@ursmtp.com
mail.smtp.password=yourPassword
to=to@email.com
from=from@email.com
subject=your subject
emailSuccessMessage=Email has been sent // I have kept this message dynamic, using it on jsp when the //email is sent successully
