Running Java Code in a JSP Page
Posted by Customer Service on 25 May 2005 12:53 AM
Java code fragments in a JSP page is called a scriptlet. This example demonstrates how to include scriptlets in a JSP page. Use the out variable to add text to the generated output:
    <%
double rand = Math.random();
if (rand < .1) {
out.println("you win!");
} else {
out.println("try again");
}
%>
This example defines a method that can be used in a scriptlet in the page:
    <%!
String getMsg() {
double rand = Math.random();
if (rand < .1) {
return "you win!";
} else {
return "try again";
}
}
%>
<%
// Use the method
out.println(getMsg());
%>
There are a number of implicit objects available to scriptlets - application, config, exception, out, pageContext, request, response, and session. These implicit objects are described in the JSP  Specification available at http://java.sun.com.
