Liferay 7 Role/ Permission issue : You do not have the roles required to access this portlet

Question

I created a PortletMVC in Liferay 7.3.0 it is deployed successfully in Tomcat 9 but when I drag it in the portal, I cannot see it and the message displayed is the following :

" You do not have the roles required to access this portlet.
"

I checked the permission of the page it was public and the guest can view it,

Can anyone please help if there is something wrong thanks. This is the classController:

@Component(
    immediate = true, 
    property = {
            "path=/login/login",
            "javax.portlet.security-role-ref=guest,power-user,user",
    },
    service = StrutsPortletAction.class
)
public class BladePortletAction extends BaseStrutsPortletAction {

    @Override
    public void processAction(
            StrutsPortletAction originalStrutsPortletAction,
            PortletConfig portletConfig, ActionRequest actionRequest,
            ActionResponse actionResponse)
        throws Exception {....}

the console display :

[SecurityPortletContainerWrapper:235] Invalid portlet ID /app_WAR_app

As the error says:

[SecurityPortletContainerWrapper:235] Invalid portlet ID /app_WAR_app

You didn't attach a unique ID to your portlet yet, you should know that in Liferay, every portlet have a unique ID (KEY) using the property javax.portlet.name

Take this code as an example:

@Component(
        immediate = true,
        property = {
                "javax.portlet.name=com_fr_bladeExamplePortlet"
        },
        properties = "OSGI-INF/portlet.properties",
        service = Portlet.class
)
public class SearchPortlet extends MVCPortlet {
}

If you are using Liferay DXP, I recommend you to work with MVCPortlet, it's simple, light, effective and ease of use.

Liferay MVC Porlet
