nothing dodgy about the pluto code
the problem is with your JSF code as the pluto returns ServletOutputStream as
seen below
org.apache.pluto.container.impl.HttpServletPortletResponseWrapper extends
HttpServletResponseWrapper
@Override
public ServletOutputStream getOutputStream() throws IOException
{
return mimeResponse != null ?
(ServletOutputStream)mimeResponse.getPortletOutputStream() :
DummyServletOutputStream.getInstance();
}
//there is one ref to ByteArrayOutputStream which doesnt make sense since
ImportSupport$ImportResponseWrapper is extending HttpServletResponseWrapper:
class
org.apache.taglibs.standard.tag.common.core.ImportSupport$ImportResponseWrapper
extends javax.servlet.http.HttpServletResponseWrapper{
public
org.apache.taglibs.standard.tag.common.core.ImportSupport$ImportResponseWrapper(org.apache.taglibs.standard.tag.common.core.ImportSupport,
javax.servlet.http.HttpServletResponse);
public java.io.PrintWriter getWriter();
public javax.servlet.ServletOutputStream getOutputStream();
public void setContentType(java.lang.String);
public void setLocale(java.util.Locale);
public void setStatus(int);
public int getStatus();
public java.lang.String getString() throws
java.io.UnsupportedEncodingException;
static java.io.ByteArrayOutputStream
access$000(org.apache.taglibs.standard.tag.common.core.ImportSupport$ImportResponseWrapper);
}
2 suggestions:
get the source
http://fisheye5.cenqua.com/browse/glassfish/appserv-jstl/src/org/apache/taglibs/standard/tag/common/core/ImportSupport.java?r=1.5&k=
1)change all java.io.ByteArrayOutputStream to javax.servlet.ServletOutputStream
(HTTP input and output streams are text streams)
2)make a method which will cast ServletOutputStream to ByteArrayOutputStream
e.g.
downcast to java.io.OutputStream
then upcast to ByteArrayOutputStream
http://java.sun.com/j2se/1.4.2/docs/api/java/io/ByteArrayOutputStream.html
Viel Gluck,
Martin Gainty
