Display Liferay portlet inside other liferay portlet

问题

I use Liferay portlet bundle 6.2 (Tomcat) and Liferay IDE(eclipse). I created two Liferay Plugin Project. In the first portlet(first plugin portlet), I save some data by using Portlet Preferences. Now, I will display second portlet in first portlet. How I can do that? I found this following code and this Link

Open portlet from other portlet

    var url;
function createRenderURL(portletId) {       
AUI().ready('liferay-portlet-url', function(A) {
    var renderURL = Liferay.PortletURL.createRenderURL();
    renderURL.setName("test");       
    renderURL.setWindowState("pop_up"); 
    renderURL.setPortletId(portletId);           
    url = renderURL.toString();
});}

But, I don't unterstand this code? I add this code to view jsp, where I can found portletId? Please, can someone explain me this a little bit? I'm new in Liferay

回答1:

It depends if your portlet is instanciable or not.

Not instanciable: your portletId should looks like Weather_WAR_WeatherPortlet

Instanciable: your portletId should looks like Weather_WAR_WeatherPortlet_INSTANCE_5aSc

You can check portletId on the table "portlet" inside your database.

If you want to get it by programmation you should use PortletConfig class

((com.liferay.portlet.PortletConfigImpl) portletConfig).getPortletId() 

NB: portletId which are number are Liferay portlet
