[Solved] Trying to add a new Struts action for Blog

[Juanjo Hernández Cánovas, modificado 10 Anos atrás.]

Hello,

I'm trying to add a new Struts Action for the Blog. I have made a hook for this new behaviour following the "how to" http://www.liferay.com/es/web/mika.koivisto/blog/-/blogs/overriding-and-adding-struts-actions-from-hook-plugins. All seems to works ok, but when I call the new action from a jsp I get this exception:

ERROR [http-bio-8080-exec-126][status_jsp:665] java.lang.ClassCastException: com.liferay.portal.struts.ActionAdapter cannot be cast to com.liferay.portal.struts.PortletActionAdapter
java.lang.ClassCastException: com.liferay.portal.struts.ActionAdapter cannot be cast to com.liferay.portal.struts.PortletActionAdapter

The hook's code is:

liferay-hook.xml

<hook>
    <custom-jsp-dir>/META-INF/custom_jsps</custom-jsp-dir>
      
    <struts-action>
    	<struts-action-path>/blogs/share_notificacion</struts-action-path>
    	<struts-action-impl>
    		com.pymoo.hook.blogs.action.ShareNotificacionAction
    	</struts-action-impl>
    </struts-action>
    
</hook>

ShareNotificacionAction Action class

public class ShareNotificacionAction extends BaseStrutsAction {
	private static final Log log = LogFactory.getLog(ShareNotificacionAction.class);
	public String execute(HttpServletRequest request, HttpServletResponse response) 
			throws Exception {
		log.info("Inside Share notificacion Action");
		return "/portal/sample.jsp"; 
	}
}

The hooked jsp view_entry_content.jsp

<%@include file="/html/portlet/blogs/init.jsp" %>

<liferay-util:buffer var="html">
	<liferay-util:include page="/html/portlet/blogs/view_entry_content.portal.jsp" useCustomPage="<%= false %>" />
</liferay-util:buffer>

&lt;%= html %&gt;

<portlet:actionurl var="shareNotificacionURL">
	<portlet:param name="struts_action" value="/blogs/share_notificacion" />
</portlet:actionurl>

<div id="<portlet:namespace />share_notificacion">
	<aui:a cssClass="share" href="<%= shareNotificacionURL %>" label="share" />
</div>

I have seen the forum entry https://www.liferay.com/es/community/forums/-/message_boards/message/13487363, but this solution doesn't work for me.

Thanks in advanced for your help.

Greetz,

You are extending wrong class. When dealing with portlet struts action you need to extend BaseStrutsPortletAction instead of BaseStrutsAction which is used for paths under /c

Hello Mika,

Thank you for your response. I tried this solution before withour good results, but it works just making a forced deploy of the hook. It doesn't works with the autodeploy on liferay sdk.

Thank you very much!

Hi Mika,

Now I'm facing a "Forward does not exist" error. Could you guide me?

Thanks in advanced,

Juanjo.

Hi one more time :-)

Digging on forum and wiki I have modified the render function to:

return originalStrutsPortletAction.render( originalStrutsPortletAction, portletConfig, renderRequest, renderResponse);

And now the error is

10:43:42,257 ERROR [http-bio-8080-exec-90][render_portlet_jsp:154] java.lang.NullPointerException

with the same result.

Any tip or advice?

Thanks in advanced,

Juanjo.

Hello Juanjo!
Did you solved this problem?
I faced with the same thing and I have no idea what the problem.
