RE: ClassCastException using Sun's jsf-portlet.jar in Pluto 2.0

take a look at the source NOT the doc
 
org.apache.pluto.container.impl.HttpServletPortletResponseWrapper
    @Override
    public ServletOutputStream getOutputStream() throws IOException
    {
        return mimeResponse != null ? (ServletOutputStream)mimeResponse.getPortletOutputStream() : DummyServletOutputStream.getInstance();
    }

and the call to javax.portlet.MimeResponse.getPortletOutputStream does return back an OutputStream
355     public java.io.OutputStream getPortletOutputStream()
356     throws java.io.IOException;

i downloaded  pluto and the portlet-spec-2.0 then did a system wide grep for ByteArrayOutputWebOutputStream and found
\Pluto>grep -S -l ByteArrayWebOutputStream *.java

i have dl latest Pluto 2.0 container sources and the latest portlet-2.0 from http://svn.apache.org/repos/asf/portals/portlet-spec/trunk/portlet-api_2.0_spec/

so my advice to you is grab the latest source ..build the jar and deploy it
OR
 take the java class with wrong signature org.apache.pluto.container.impl.HttpServletPortletResponseWrapper.java and change the signature so getOutputStream method returns ServletOutputStream instead of incorrect com.sun.faces.portlet.ByteArrayWebOutputStream
