To display an item with view_item you have to pass item in the request.
Now you have NPE because it's impossible to get an item. Just add the item to the request.

You need to add itemId as a parameter to your URL:
item is the item object that you want to show.
Try to explore shopping portlet source code, it's clear and very interesting, I think, that you'll find many answers there.
<portlet:renderurl var="redirectURL">
<portlet:param name="struts_action" value="/shopping/view_item" />
<portlet:param name="redirect" value="<%= currentURL %>" />
<portlet:param name="itemId" value="<%= String.valueOf(item.getItemId()) %>" />
</portlet:renderurl>
item is the item object that you want to show.

There should be a "caused by" row in the stacktrace little further down. This row should tell you what's wrong.

Sasmita, you didn't passed shopping item, and still got the same NPE.
