How to redirect or forward a page

[steve loh <sl...@kiala.com>]

I encounter a problem in redirecting/forwarding a page in jetspeed. I
know how to forward page between a same portlet by using setTemplate
method. But I can't get to forward to another URL. I have try two ways,
by redirecting in action class and in jsp page, they just don't work:

**Action class**
public void doPrintlabel(RunData rundata, Portlet portlet) {
    rundata.getResponse().sendRedirect("http://www.google.com");
}
 

**jsp page in a portlet**
<% response.sendRedirect("http://www.google.com"); %>
or 
<jsp:forward page="http://www.google.com" / >

In both case, the error I received says that the page cannot be
redirected because the response header has been sent. How can I bypass
this? Any suggestion on page redirect/forward will be helpful! Thanks!
