Hi. TextFilters are working fine now. The problem is that several plain text well-known mime-types are not supported. For example, text/html, text/xml, text/css, text/sgml, ...
All of these are plain files, but TextPlainTextFilter won't recognize them because it only handles text/plain mime types. So common files like HTML ones are not indexed currently with jackrabbit. So, or new filters are added, or TextPlainTextFilter should be modified to handle these files. If you want to create new filters, I could do it because I need it :) Also some time ago I did a filter for handling RTF files. It uses HTMLEditorKit JFC classes. I could contribute it if you find interesting. Regards. Martin
