Indeed there is a DTD file at that new location. The problem seems to be that is is not served with the right "Content-Type" header. At least that is my conclusion.
The command "curl --verbose --location http://www.netbeans.org/dtds/filesystem-1_2.dtd"; reveals that the server returns the following: < HTTP/1.1 200 OK < Date: Mon, 08 Mar 2021 10:35:56 GMT < Server: Apache < Last-Modified: Tue, 27 Oct 2020 17:24:19 GMT < ETag: "7c1-5b2aa513232d5" < Accept-Ranges: bytes < Content-Length: 1985 < Access-Control-Allow-Origin: * < <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

But I would have expected the server to set a Content-Type, for example I guess "Content-Type: application/xml-dtd" would be appropriate. The missing Content-Type explains why a browser displays nil, but it doesn't necessarily explain why the NetBeans Platform won't download and use that DTD. We need to check if the mechanism which downloads these DTDs is set to follow redirects. I would assume so. Secondly we need to check if the mechanism is sensitive omission of the Content-Type header. /Lars On Mon, Mar 8, 2021 at 11:24 AM Jens Hofschröer <[email protected]> wrote: > > Hi everybody > > With the end of life of netbeans.org on Oracle infrastructure we > encounter a problem with DTD adresses in (old?) build systems. > > For example our current RCP app is based on Apache NetBeans 12.0.
