使用jasperreports-5.6.0.jar导致的问题

Struts2+jasperReport5.6如下设置：

<!-- 社员档案 -->     <package name="com.anche.qh.arc.arcMember" extends="json-default">         <result-types>             <result-type name="jasper" class="org.apache.struts2.views.jasperreports.JasperReportsResult" />         </result-types>                  <action name="arcMember_*" class="actArcMember" method="{1}"> <result type="json">                 <param name="root">jsonResult</param>             </result> </action>   <action name="arcMemberStr_*" class="actArcMember" method="{1}">             <result type="json">                 <param name="root">returnStr</param>             </result>         </action>                  <action name="arcMemberPdf_*" class="actArcMember" method="{1}">             <result name="success" type="jasper">                 <param name="location">/reportSource/arc/member.jasper</param>                 <param name="dataSource">list</param>                 <param name="format">PDF</param>             </result> </action>     </package>

 
运行系统提示错误如下：

解决问题：

参考（http://bbs.csdn.net/topics/390861809）说是因为JasperReport版本的问题，

于是安装iReport5.2，并用里面的

和替换原来的jar包

，问题解决。
