Re: Exception while deploying the JSR168 portlet on WSRP4J stack.

[Julie MacNaught <jm...@apache.org>]

I can't really tell what's going on, but the best way to deploy a new 
portlet is to ask pluto to do it for you, since we are using pluto as 
the portlet container.  If you look at the maven.xml file in the 
testportlet directory, you can see that there is a pluto class that 
takes a war file as an argument and the path to the producer's webapp.

But when I try to consume a new portlet I face following exception. For deployment I am following the instructions provided at URL http://portals.apache.org/wsrp4j/gettingstarted/config.html
