Send mail using Jsp and Servlet.

hello firends,

using this blog you can send mail using JSP and Servlets, follow the following steps to design this application

Send mail using Jsp and Servlet.

Create new web project using netbean.
For this project following 5 labraries are requered.

a. activation.jar

b. mail.jar

c. mailapi.jar

d. pop3.jar

e. smtp.jar

3. After adding this library in project bellow code is copy and paste in index.jsp file.

****************************************************************

after that create one Java Frame with one Text Box, one Button and labels, design same like as above image

after that at Button Click Event (ActionPerformed event) add following code.....

*************************Code***********************************

int Number = Integer.parseInt(txtNumber.getText());
   String No2String = EnglishNumberToWords.convert(Number)+"";
   txtString.setText(No2String);

in this code assign text box value to a "Number" variable and pass this value to the Function in above code "EnglishNumberToWords.Convert(Number)" and after that print the value
