When Using JSP to send Sina mail, the following exception is always reported. Later, you only need to modify the information as follows:

1 properties props = system. getproperties (); 2 // specify SMTP Server 3 props. put ("mail. SMTP. host ", smtphost); 4 props. put ("mail. SMTP. auth "," true "); // true must be enclosed by quotation marks

Enclose true with quotation marks.
