问题
I develop an example of Struts2 with Jasper Reports and every thing work fine. In my index.jsp I have
index.jsp:
<body>
<a href="HTML.action" target="_blank" >click to generate pdf report</a>
</body>
struts.xml:
<struts>
<package name="default" extends="struts-default,jasperreports-default">
<action name="HTML" class="com.tutorialspoint.DataBeanList" method="exporte">
<result name="success">/index.jsp</result>
</action>
</package>
</struts>
but when I want to do that with Liferay 6.0.6 I got this error:
INFO [PortalImpl:3829] Current URL /web/guest/HTML.action generates exception: null
In my struts.xml I have:
<!-- Action pour générer un rapport pdf -->
<package namespace="/reporting" extends="struts-portlet-default,json-default,jasperreports-default" name="reportingview">
<action name="HTML" class="com.xxxxxx.struts2.actions.genererQPpdf" method="exporte">
<result name="success">/JSPs/reporting/resultQP.jsp</result>
</action>
</package>
so any one can help me.
回答1:
Better use the struts tags to exclude errors in the code. For example url tag could be used to construct the correct link that point to the action.
<a href="<s:url namespace="/reporting" action="HTML"/>" target="_blank" >click to generate pdf report</a>
