Module dtds not found

[branflake2267]

Are the module dtd files on this site?

http://gwtproject.org/doctype/2.7.0/gwt-module.dtd

@branflake2267 The link is the official one but it seems that it is broken.

You will always get a HTTP 301 (Moved Permanently) response if you request a file other than html (which is true for dtd-files).
The cause for this issue is the server code of the gwt-site-webapp:

      if (!fullPath.endsWith("/")) {
        fullPath = fullPath + ".html";
        e = getResourceByKey(fullPath);
        if (e != null) {
          // redirect so we use correct urls!
          resp.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
          resp.setHeader("Location", "/" + fullPath);
          return;
        }
      }

So someone has to fix this code to solve this issue, but for repo 'gwt-site-webapp' it is not clear if contributions are welcome and the official code isn't hosted @ Github:

Nope, this code is only triggered if the resource cannot be found in the data store. So if DTD links don't work, then it should mean they're not in the data store. Possibly a deployment problem then.

Their hashes are in the DocHash collection: http://www.gwtproject.org/hash?count=0, that probably means they'll never going to be uploaded again, so if they're missing in the actual document store then redeploying the site won't fix it.

I suppose you are wrong. Have a look at this point in the code:

fullPath = fullPath + ".html";

For all paths the String ".html" is added before searching in the datastore. This ends up in the following I think when searching for dtd file: "doctype/2.7.0/gwt-module.dtd.html" which of course can't be found.

[tbroyer]

You omitted the lines just above 😉

String fullPath = normalizePath(req.getRequestURI());

Entity e = getResourceByKey(fullPath);

if (e == null) {
  // temporary try to find the resource with .html appended
  // due to redirects from developers.google.com

Hm, right! The classic if-cascade. Whatever happened here it ends in a HTTP 301:

Don't know if the code alone can explain this behaviour.

If you use these links it works:

http://www.gwtproject.org/doctype/2.7.0/gwt-module.dtd
http://www.gwtproject.org/doctype/2.8.2/gwt-module.dtd

comparing to these which redirect to gwt-project page:

http://gwtproject.org/doctype/2.7.0/gwt-module.dtd
http://gwtproject.org/doctype/2.8.2/gwt-module.dtd

Ommitting 'www' will break the links.

Don't know if this knowledge is sufficiant to close this issue. In my opinion it should also work without 'www'.
