web.xml配置：
                    <servlet>
<servlet-name> DisplayChart </servlet-name>
<servlet-class> org.jfree.chart.servlet.DisplayChart </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> DisplayChart </servlet-name>
<url-pattern> /servlet/DisplayChart </url-pattern>
</servlet-mapping>
action调用方法生成   graphURL   传递到jsp中：
public   String   getPicture()   throws   IOException
{
HttpSession   session   =     ServletActionContext.getRequest().getSession();
AVote   vote   =   new   AVote();
vote.setPictype( "pie ");
vote.setTitle( "您最喜欢的电影？ ");
String   filename   =   Tryitshow.generatePieChart(iVoteService.getVoteResult_Ser(1),   vote,   session);
graphURL   =   ServletActionContext.getRequest().getContextPath()+
"/servlet/DisplayChart?filename= "   +   filename;
return   "doVoteQuery ";
}

jsp中这样引用的：
<img   src= ' <s:property   value= "graphURL "/> '   width=500   height=300   border=0>

整了一天各种方法都试过了。。就是没用。。急求各位帮助~谢啦
