Use (more readable) for SO:

<%@ page import="org.jfree.data.general.DefaultPieDataset" %>
<%@ page import="org.jfree.chart.ChartFactory" %>
<%@ page import="org.jfree.chart.JFreeChart" %>

You can only import a type, so this will not work:

<%@ page import="org.jfree.chart.servlet.*" %>

And make sure jfree library is included:

<!-- https://mvnrepository.com/artifact/jfree/jfreechart -->
<dependency>
    <groupId>jfree</groupId>
    <artifactId>jfreechart</artifactId>
    <version>1.0.13</version>
</dependency>
