A scriptlet can contain any number of JAVA language statements, variable or method declarations, or expressions that are valid in the page scripting language.
Following is the syntax of Scriptlet −
<% code fragment %>
You can write the XML equivalent of the above syntax as follows −
<jsp:scriptlet> code fragment </jsp:scriptlet>
Any text, HTML tags, or JSP elements you write must be outside the scriptlet. Following is the simple and first example for JSP −
<html> <head> <title>Hello World</title> </head> <body> Hello World!<br/> <% out.println("Your IP address is " + request.getRemoteAddr()); %> </body> </html>
