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
