To extend the CreateAccountAction , there are different types of hook to achieve . Here we are going to discuss about Struts Action Hook.
Steps 1 : Add the struts action path and your custom implementation file in liferay-hook.xml :
<struts-action>
<struts-action-path>/login/create_account</struts-action-path>
<struts-action-impl>com.liferay.login.hook.action.CustomCreateAccountAction</struts-action-impl>
</struts-action>
Step 2: Create custom implemetation file [CustomCreateAccountAction] in above mentioned location . [com.liferay.login.hook.action]
public class CustomCreateAccountAction extends BaseStrutsPortletAction{
public CustomCreateAccountAction() {
// TODO Auto-generated constructor stub
}
@Override
public void processAction(StrutsPortletAction originalStrutsPortletAction,
PortletConfig portletConfig, ActionRequest actionRequest,
ActionResponse actionResponse) throws Exception {
// TODO Auto-generated method stub
System.out.println("inside the process actionwhile creating the account>>>");
super.processAction(originalStrutsPortletAction, portletConfig, actionRequest,
actionResponse);
}
@Override
public String render(StrutsPortletAction originalStrutsPortletAction,PortletConfig portletConfig,
RenderRequest renderRequest, RenderResponse renderResponse)
throws Exception {
// TODO Auto-generated method stub
System.out.println("inside the render action while creating the account>>>");
return super.render(portletConfig, renderRequest, renderResponse);
}
}
Step 3: deploy.
Done. But sometime you might confuse when we need to extend BaseStrutsPortletAction and BaseStrutsAction.
Struts action interfaces:
com.liferay.portal.kernel.struts.StrutsAction
com.liferay.portal.kernel.struts.StrutsPortletAction
The StrutsAction interface is for regular Struts actions, like /c/portal/update_email_address, from the portal.
The StrutsPortletAction interface is used for similar Struts actions from portlets.
Note: If you use BaseStrutsAction, you should override "execute" method:
public class SampleStrutsAction extends BaseStrutsAction {
@Override
public String execute(StrutsAction originalStrutsAction, HttpServletRequest request, HttpServletResponse response) throws Exception {
System.out.println("SampleLayoutStrutsAction.execute() - " + request.getRequestURI());
return originalStrutsAction.execute(request, response);
}
}
Exceptions :
1. "Cannot be Cast" Exception
Some time if you get an exception like "ActionAdapter cannot be cast to PortletActionAdapter" or "PortletActionAdapter cannot be cast to ActionAdapter"
To resolve that:
) ActionAdapter cannot be cast to PortletActionAdapter :
you have implemneted BaseStrutsAction instead of BaseStrutsPortletAction
2) PortletActionAdapter cannot be cast to ActionAdapter :
you have implemneted BaseStrutsPortletAction instead of BaseStrutsAction
2. "Forward Does not exist" Exception
If you get an exception like this , then In render method of custom implementation file [CustomCreateAccountAction ] before return statement,
we need to change that behavier by setting renderRequest.setAttribute(WebKeys.PORTLET_DECORATE, Boolean.TRUE);
use this :
String ret = originalStrutsPortletAction.render(null, portletConfig, renderRequest, renderResponse);
renderRequest.setAttribute(WebKeys.PORTLET_DECORATE, Boolean.TRUE);
return ret;
instead of ,
return originalStrutsPortletAction.render(null, portletConfig, renderRequest, renderResponse);
3. If It doesn't redirect to Original Path
After successfully implementing struts action hook, If it doesn't redirect to it's original path, you need to use originalStrutsPortletAction in processAction method.
For example after creating the user , if it stays in same create account page instead of login page which is default behaviour, then use like this :
originalStrutsPortletAction.processAction(portletConfig, actionRequest, actionResponse);
instead of,
super.processAction(originalStrutsPortletAction, portletConfig, actionRequest,actionResponse);
