How to Know if Your Server Has JavaMail
The JavaMail client contains several libraries you use to send mail from a JSP Web page. To identify if the server has JavaMail and its libraries configured for your JSP application, include it in a test JSP page. If the page sends an error for the file, you don't have JavaMail. If the JSP page executes successfully with the JavaMail include files, your server includes JavaMail.

Save the file and click "Run" in the JSP editor to run the file on the server and in your default browser. If the page returns "Error on Line 1," you know that the server doesn't contain the JavaMail server files. If no error is presented, you know your server contains JavaMail.
