具体的请查看源码：

struts2-jasperreports-plugin-2.2.3.jar

下面 JasperReportsResult.class文件

①提取px.gif图片

在jasperreports-4.5.1.jar中查找

具体路径如下：

jasperreports-4.5.1\net\sf\jasperreports\engine\images\pixel.GIF

重命名为px.gif放在项目的images文件夹下面。

②修改Struts2配置文件：

<package name="px" namespace="/images" extends="struts-default">
         <action name="px">
                 <result>/images/px.gif</result>
   </action>
</package>
