regression: Since 1.1.1, JSFs can't send raw data to response
-------------------------------------------------------------
Key: MYFACES-1130
URL: http://issues.apache.org/jira/browse/MYFACES-1130
Project: MyFaces
Type: Bug
Versions: Nightly
Reporter: Ramon Casha
Since v1.1.1, it is not possible for a JSF page to send raw bytes to the
response, such as a PDF from JasperReports, because bytes >127 are always
converted to numeric entities even in raw data sent to
response.getOutputStream(). Ideally, such character translation should only
occur on the Writers, not on the OutputStreams, and/or only when the response's
contentType is of an html/xml type.
Error is caused in:
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(request,
response, chain)
Recommended solution: if response content type is not a text type (eg,
"application/pdf"), make no attempt to encode bytes sent directly to
outputstream.
Workaround: in the doFilter method, after the extendedResponse.finishResponse
call, if the entendedResponse's contenttype was set to a non-text type, send
the output directly without any translation. As a stop-gap solution I did this:
if(extendedResponse.getContentType().contains("pdf")) {
servletResponse.getOutputStream().write(
extendedResponse.getBytes() );
return;
}
