                    <servlet-class> org.jfree.chart.servlet.ChartServletDemo </ servlet-class>
                </ servlet>
                <servlet-mapping>
                    <servlet-name> ChartServletDemo </ servlet-name>
                    <url-pattern> / servlet / ChartServletDemo </ url-pattern>
                </ servlet-mapping>

An error occurred: ParserUtils: warning org.xml.sax.SAXParseException: URI was not reported to parser for entity [document]

Just import jcommon.jar and jfreechart.jar, don’t import other packages
