Description
As you know, JavaMail API makes your JSP/Servlets mail ready. But, you may want to send the e-mails at the scheduled time in the future, rather than send the e-mails immediately. By OOP MailScheduler, a few lines of code are enough for your JSP/Servlets to send the e-mails at the scheduled time. The scheduled time can be specified by any Time Zone (Java TimeZone).
The e-mail will be stored into the SQL table by Object Serialization. Then, at the scheduled time, the back-ground Thread will select it and send it to the SMTP server through JavaMail API. If the communication with the SMTP server fails, the back-ground Thread will retry to send the e-mail upto the specified count. In addition, you can cancel to send the queued e-mail.
Even if you'd like to send the e-mails immediately, it is desirable to avoid the over-head between JavaMail API and the SMTP server. Before your JSP/Servlets sends its response back to the web browser, the JSP/Servlets needs to wait the response from the SMTP server. This over-head will be apparent when the multiple requests arrive in your JSP/Servlets concurrently.
OOP MailScheduler ensures the sequential access to the SMTP server, which avoids the over-head and makes your JSP/Servlets on Apache Tomcat truly Thread Safe. Take the full advantage of JavaMail API by the help of OOP MailScheduler.
