Example 2: Server-Side Include
<HEAD><TITLE>Hello World SSI</TITLE></HEAD>
<H1>A Server Side Include Sample</H1>
<SERVLET NAME=“HelloWorld">
<PARAM NAME=“from" VALUE=“me">
Servlets might be invoked on the server side as a side effect of accessing an HTML page, transparently to the client.
Constant parameters are passed explicitly from HTML (init parameters may be specified in SERVLET block).
The servlet’s input is an empty stream; its output replaces the body of the <SERVLET> block in the HTML returned to the client.
