Obtain ServletContext or PortletContext in portlet

[12年前 に Seyed Mohammad Hosein Jamali によって更新されました。]

Hello All

I want to use below code in a portlet that created by Liferay IDE to obtain ServletCotext.

ServletContext sc = ((PortletContextImpl)req.getPortletSession().getPortletContext()).getServletContext();

where req is of type RenderRequest , but i get this exception :
com.liferay.portlet.PortletContextImpl cannot be cast to org.apache.pluto.core.impl.PortletContextImpl

Definition of later PortletContextImpl is :

public class org.apache.pluto.core.impl.PortletContextImpl implements javax.portlet.PortletContext, org.apache.pluto.core.InternalPortletContext {

How can i use of com.liferay.portlet.PortletContextImpl without using portal-impl.jar ?
Is there a better way to obtain ServletContext ?

Cheers ,
S.M.H. Jamali

I would try to cast this not to org.apache.pluto.core.impl.PortletContextImpl but to javax.portlet.PortletContext;

[12年前 に Seyed Mohammad Hosein Jamali によって更新されました。]

of course i can cast to javax.portlet.PortletContext too , but i need to cast to PortletContextImpl ! as i need call getServletContext() of PortletContextImpl !
I need to access the ServletContext of portlet

Any help appreciated

Hi Seyed,

Try using below code

String portletId = "your-portlet-id";
com.liferay.portal.kernel.portlet.PortletBag portletBag = com.liferay.portal.kernel.portlet.PortletBagPool.get(portletId);
ServletContext servletContext = portletBag.getServletContext();

Hope it helps

I find out a simple way for obtaining the ServletContext :

HttpServletRequest request = PortalUtil.getHttpServletRequest(req);
ServletContext servletContext = request.getSession().getServletContext();

req is of type RenderRequest

Thats it
