This is a fantastic feature, most awaited to get realized thru a hook plugin. Nice Job Mika and Brian. Thank you so much.

We just made it even more powerful by passing in reference to the original action so that you can just wrap it if you so wish.

Awesome feature. Is it possible to create custom services in hook and then call the new services from these overrided struts action? And any hint on when liferay 6.0 EE SP2 will be released so that i can use these in my project?

Yes you can use custom services in the hook plugin from the action classes.

Nice!
Do you know if is possible to override an struts action in a hook without using ext--enviroment in liferay 5.2.3? Because in the DTD hook of liferay 5.2.3 there are the <struts-action> tags... but know I see that this will be a new functionality of liferay 6.1.
I'm little bit confusing.
Can anyone help me?
Thank you.
Mika Koivisto
7/13/11 11:32 AM
Mike and Roberto this is only available in upcoming 6.1 and 6.0 EE SP2 and 5.2 EE SP6. Neither 6.0 CE or 5.2 CE has this feature as it was developed after their release.
Hi Roberto,
I've posted the jar, and a sample hook for Liferay 5.2.3 with the module I was talking in the other post. As told, using that you'll be able to override/add struts configs and actions, tiles configs, spring beans, plus any other thing Liferay allow you to do using hook.
You can check that sample out at http://aigloss.blogspot.com/2011/07/liferay-portal-server-avoiding-use-of.html
Hope you like it!

Hi Aig, is there something like zeep-o-tron for Liferay 6.0.6?
I have'nt tested it yet for that Liferay version, but, unless there is some package modification or something like that, it will surely work.
I'll try to test it and upload a working sample for LF 6.0.6 during this week. Just uploaded it for 5.2.3 first because of Roberto needs.

Hi Alex,
finally I've found some time to test it on LF 6.0.6 and make some modifications. You can find the details here: http://aigloss.blogspot.com/2011/07/zeep-otron-for-liferay-6.html.
Hope you like it!

I am trying to create a hook plugin by extending the class EditPagesAction .I have provided my version of action class with name NPPEditPagesAction.I am able to deploy my plugin into liferay .But I am not able to excute my implemention class code given in NPPEditPagesAction.I tried to set breakpoint in my code but I am not able to get the Debug perspecetive in eclipse.

Was a very nice feature and i tried and implemented it successfully. I have small requirement not sure that is doable or not, i need to redirect to an existing Struts Action in one of the conditions during the render of the BaseStrutsPortletAction case. e..g redirecting to path "login/login"

Rajesh Chaurasia, are you sure you have the right struts-path? Some of the paths are changed automatically by com.liferay.portal.struts.StrutsActionPortletURL so that the path matches the struts-path of the portlet. This can be quite confusing because the struts path in the jsp is different that what is actually rendered.
Mika Koivisto
10/24/11 10:39 AM
Kamesh Sampath, can you provide me a example of how would you do that with plain Struts? It might be possible if it's not then it might be something to consider adding.
Ray Augé
10/24/11 10:47 AM
Isn't this supported by simply delegating those cases back to:
"originalAction" which is the value of the execute's method ActionMapping parameter?
Mika Koivisto
10/24/11 10:53 AM
Ray that would only work if you are overriding that particular action. If you want to redirect from one action to another it would work. Well you could use response.sendRedirect().

I ve a similar problem of Rajesh Chaurasia
i want override ...action.GetCategoriesAction
so i write the liferay-hook.xml
<struts-action>
<struts-action-path>/asset/get_categories</struts-action-path>
<struts-action-impl>it.reply.open.wt.asset.action.GetCategoriesAction</struts-action-impl>
</struts-action>
but when in my code it invokes this action it uses :
url: themeDisplay.getPathMain() + '/asset/get_categories'
adding the pathMain ( that in my case is /c/ ) so it cant find the action class...
but if i dont add the pathMain it cant find url.
there is a solution for this?

Great, informative article! Really useful feature!
But I was stuck in one silly mistake in my liferay-hook.xml. The ORDER of elements really MATTERS!
It should be as described in "liferay-hook_6_0_0.dtd" (don't pay attention to version).
My liferay-hook.xml was:
<hook>
<custom-jsp-dir>/WEB-INF/custom_jsps</custom-jsp-dir>
<portal-properties>portal.properties</portal-properties>
</hook>
This needed to be:
<hook>
<portal-properties>portal.properties</portal-properties>
<custom-jsp-dir>/WEB-INF/custom_jsps</custom-jsp-dir>
</hook>
I had problems to deploy it, and have gotten such ERROR:

Great feature so far! ... but...
I am trying to create a jsp-Hook for the portlet-configuration tabs. I already figured out, my struts action has to extend BaseStrutsPortletAction. But if I add my own Action there, I get the error
2011-12-12 16:04:00 ERROR [PortletRequestProcessor:377] Forward does not exist
Any help or hint would be great!

I'm able to wrap the message_boards/view action as you describe here. But when I attempt to wrap /login/facebook_connect_oauth I get a runtime exception: com.liferay.portal.struts.PortletActionAdapter cannot be cast to com.liferay.portal.struts.ActionAdapter.
If I instead extend the class BaseStrutsAction as below, the facebook login functionality ceases to work properly. Is there something fundamentally different about the FacebookConnectAction class or am I doing something wrong?
public class FacebookMyConnectAction extends BaseStrutsAction {
@Override
public String execute(StrutsAction originalStrutsAction,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
// TODO Auto-generated method stub
return super.execute(originalStrutsAction, request, response);
}

This is a nice feature indeeed, but there seems to be a bug when wrapping actions that are sending redirects. In my case I'm trying to wrap com.liferay.portal.action.LoginAction (/c/portal/login) with a custom action.
In liferay-hook.xml I have the following:
<hook>
<portal-properties>portal.properties</portal-properties>
<struts-action>
<struts-action-path>/portal/login</struts-action-path>
<struts-action-impl>PortalLoginAction</struts-action-impl>
</struts-action>
</hook>
Then, my PortalLoginAction -class has the following appearance:
public class PortalLoginAction extends BaseStrutsAction {
@Override
public String execute(StrutsAction originalStrutsAction, HttpServletRequest request, HttpServletResponse response)
throws Exception {
//custom code
return originalStrutsAction.execute(request, response);
}
}
Everything works well here until reaching the execution of the original action. The problem seems to be that LoginAction.execute() uses response.sendRedirect() and returns null. The execute() method in com.liferay.portal.struts.StrutsActionAdapter in turn expects the original action to return an ActionForward, thus resulting in a NullPointerException (line 48).
Does anyone know a workaround for this problem? I'm using Liferay 6 EE SP2 and I wouldn't like to make any custom fixes to the code.

I have also hit the same exact problem as Rex Petersen has above. In my case I am trying to override the action for the UpdateReminderQueryAction. The blog post does not make it obvious why the wrapper example above is extending BaseStrutsPortletAction. It is doing so because the action class for message boards view extends PortletAction.
Rex, in the body of your execute method listed above replace the call to super.execute() with this instead:
return originalStrutsAction.execute(request, response);
Mika, if you could enhance your blog to mention this part of the process it would be greatly appreciated.
Mika Koivisto
1/6/12 1:56 PM
Hey can you open a ticket for this and post the ticket number here. It should work with returning null as the forward.
Trevor Ackerman
1/9/12 1:53 PM
I'm assuming you are responding to Jon Haikarainen. right?
Jon Haikarainen
1/10/12 3:35 AM
Finally I got the ticket for the NullPointerException -case created: LPS-24734.
Personally I don't however have a problem with this anymore as it turned out that customizing the action wasn't necessary in this case.
Is this supported in 6.0.6 CE
Mika Koivisto
1/18/12 12:46 PM
R V this is implemented in 6.1.0 CE and backported to 6.0 EE SP2 so not available in 6.0.6 CE.

When I override an existing JSP e.g. lets say blogs/search.jsp, I faced couple of problems
1. I am not able to use the existing struts path "/blogs/search" eventhough I override the same in my hook.xml, its picking my class only when I give a alternate search path like "/blogs/search1"
2. When i return the existing JSP page via the Struts Portlet Action render method I see the basic Portlet CSS styles are gone.
Any thoughts on what I am missing and ways to fix them ?
