Re: Exception while using proxyPortlet!

[Peter Fischer <pf...@apache.org>]

Mandeep,

the Proxy Portlet is a JSR168 portlet and the corresponding .war file
contains a portlet and not a regular servlet.
So you cannot invoke the portlet like a servlet by sending a request to the
URL you mentioned below.
You will have to deploy the portlet in a portlet container and add the
portlet to page to invoke it.

Regards, Peter
