The filter is also necessary anytime your JSP page is included in another page; it looks like some/many (I'm using Jetty) containers will not let an included page reset the content type, and you won't be able to clear the already write()'d content. Here are the files w/ displaytag packages. TableTag#writeExport should add pageContext.getRequest().setAttribute(org.displaytag.util.ResponseOverri deFilter.CONTENT_OVERRIDE_TYPE, pMimeType); pageContext.getRequest().setAttribute(org.displaytag.util.ResponseOverri deFilter.CONTENT_OVERRIDE_BODY, pExportString); at line 867. > Thanks! > > Matt > > On Monday, September 29, 2003, at 10:17 AM, Andy Pruitt wrote: > > > Ok, here is a fix for the dreaded "no export in tiles or included > > jsps" problem. > > > > This fix allows exports to work seamlessly, without > requiring the JSP > > author to duplicate the table tag, although it does require > a filter > > to be added to web.xml. > > > > The trick is that I changed the writeExport() method of TableTag to > > write the output into the Request object instead of to the page.
