Email sending program V1.1

This is a servlet application ..

The first is the Web. xml file.

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <web-app version = "2.5" xmlns = "http://java.sun.com/xml/ns/javaee" <br/> xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xsi: schemalocation = "http://java.sun.com/xml/ns/javaee <br/> http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <br/> <servlet-Name> sendmailservlet </servlet-Name> <br/> <Servlet -Class> COM. jadyer. servlet. sendmailservlet </servlet-class> <br/> </servlet> <br/> <servlet-mapping> <br/> <servlet-Name> sendmailservlet </servlet-Name> <br/> <URL-pattern>/servlet/sendmail </url-pattern> <br/> </servlet-mapping> <br/> <welcome-file-List> <br/> <welcome-File> Sendmail. JSP </welcome-File> <br/> </welcome-file-List> <br/> </Web-app>

The sendmail. jsp page is used to enter the content of the sent mail.

<% @ Page Language = "Java" contenttype = "text/html; charset = UTF-8 "%> <br/> <center> <br/> <H2> <font color =" blue "> email sender V1.1 </font> </H2> </P> <p> <form action = "<% = request. getcontextpath () %>/servlet/sendmail "method =" Post "> <br/> <Table border =" 22 "> <br/> <tr> <br/> <TD> recipient </TD> <br/> <TD> <input type = "text" name = "to" size = "30"> </TD> <br/> </tr> <br/> <tr> <br/> <TD> sender </TD> <br/> <TD> <input type = "text" name = "from" Size = "30"> </TD> <br/> </tr> <br/> <TD> subject </TD> <br/> <TD> <input type = "text" name = "subject" size = "30"> </TD> <br/> </tr> <br/> <tr> <br/> <TD valign = "TOP"> body </TD> <br/> <TD> <textarea Cols = "50" rows = "15" name = "Body "> </textarea> </TD> <br/> </tr> <br/> <TD> & nbsp; </TD> <br/> <TD> <input type = "Submit" value = "Submit"> </TD> <br/> </tr> <br/> </table> <br/> </form> <br/> </center>

Next is the sendresult. jsp page used to display the mail sending result.

<% @ Page Language = "Java" contenttype = "text/html; charset = UTF-8 "%> </P> <p> <font color =" red ">$ {requestscope ['sendmail. message ']} </font>

During the test: Enter the details of the email you want to send on the sendmail. jsp page.

Recipient: Enter the recipient's email address.

Sender: Enter the jadyer@yeah.net, that is, my email address. This is restricted by line 44th of sendmailservlet. java.

Subject and body: Try to Enter Text of some meaning. Otherwise, the email is easily processed by the recipient's email server as spam, leading to sending failure.
