Hello,
How can i exclude the response of a download-action for the
extension-filter?
My bean write the result directly to the faces-response:
private boolean writeOutContent(final HttpServletResponse res, final
File content, final String theFilename) {
boolean result = true;
if (content != null) {
try {
res.reset();
final WritableByteChannel writeChannelOut =
Channels.newChannel(res.getOutputStream());
final ReadableByteChannel readChannelIn =
Channels.newChannel(new FileInputStream(content));
res.setHeader("Pragma", "no-cache");
res.setDateHeader("Expires", 0);
// set content type so that the browser shows xml filter in save
dialog
res.setContentType("text/xml");
res.setHeader("Content-disposition", "attachment; filename=" +
theFilename);
ChannelTools.fastChannelCopy(readChannelIn, writeChannelOut);
} catch (final IOException e) {
result = false;
}
} else {
result = false;
}
return result;
}
private String download() {
final FacesContext facesContext = FacesContext.getCurrentInstance();
writeOutContent(getServletResponse(), new File(this.filename),
getFilename());
facesContext.responseComplete();
return null;
}
I found these lines in ExtensionFilter:
public boolean isValidContentType(String contentType)
{
return contentType.startsWith("text/html") ||
contentType.startsWith("text/xml") ||
contentType.startsWith("application/xhtml+xml") ||
contentType.startsWith("application/xml");
}
I must return a text/xml but i dont want filter the content with the
extension-filter. Is this possible?
My web.xml:
<filter-mapping>
<filter-name>MyFacesExtensionsFilter</filter-name>
<servlet-name>FacesServlet</servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name>MyFacesExtensionsFilter</filter-name>
<url-pattern>*.jsf</url-pattern>
</filter-mapping>
