title: How to create a jsp Form with validation and mail form details to administrator?
body: <p>I am new to JSP and related technologies. I need to write a JSP form with some required fields (including Captcha), the form will require validation. Upon successful submission of the form, it should be able to email to a stated email address which is grabbed/parsed from a .txt file. </p>
  
  <p>That is basically the flow. But technically how should I do it in JSP/java? Is there any good tutorial referencing to my above form requirement? How should I be able to grab/parse the text file. And lastly,
  I remembered that php has a function called mail() to do the emailing, how should I do it in jsp?</p>
  
  <p>Thank you very much.</p>
