Example 1: Invoking a Servlet by URL

Most servers allow a servlet to be invoked directly by URL.

• client issues HTTP GET
  e.g., http://www.yourhost/servlet/HelloWorld
  
• servlet specified by HTTP POST
  e.g., with form data
  

<FORM ACTION=“http://yourhost/servlet/HelloWorld" METHOD=“POST">

From : <INPUT TYPE=“TEXT" NAME=“from" SIZE=“20">

<INPUT TYPE=“SUBMIT" VALUE=“Submit"> </FORM>

generates a URL-encoded query

string, e.g., “<servletURL>?from=me”
