JavaMail

[Hengtai Yu]

Hi, I try to use JavaMail-1.1.2 to send email from servlets. When I use example to test, messages are: java.lang.NoClassDefFoundError: javax/mail/Session at JavaMailServlet.doPost(JavaMailServlet.java:35). I check line 35 in JavaMailServlet.java, they are: Properties props=3D new Properties(); props.put("mail.smtp.host",host);    //**** this is line 35 ******** Session ssn =3D Session.getDefaultInstance(props,null); Does any one know  what is wrong here? Thanks Hengtai
