Subject Re: Third party portlets do not work in M2
Date Mon, 11 Apr 2005 15:52:59 GMT
I got this same error when I installed the j2M2 binary release.  I
went to http://portlet-opensrc.sourceforge.net/index.htm and
downloaded the google portlet, then dropped it into the
jetspeed/WEB-INF/deploy directory.  That worked and now the google
portlet works.
