OK, I've made this work with Kaffe. It requires some hackery though.
Get Jigsaw from the above URL. Apply the following patches in the
directory www/protocol/http:

(The first modification is to allow HttpURLConnection to be instantiated
from outside the org.w3c package hierarchy and the second works around
the unimplemented (as of 1.0b3) socket timeout feature in Kaffe.)
The following is a very rough first-cut at HttpURLConnection.java (which
strictly belongs in libraries/javalib/java/net). Compile it and put the
location of the compiled class in your classpath. (Lots of functionality
is missing from this class but I have used it to fetch simple http URLs.
YMMV.)

Finally, you need a Kaffe handler class for the http protocol. This is
one which instantiates the w3c.org implementation. Build it and put
the location of the compiled class in your classpath.

package kaffe.net.www.protocol.http;
import java.net.URLStreamHandler;
import java.net.URLConnection;
import java.net.URL;
public class Handler extends URLStreamHandler {
protected URLConnection openConnection (URL u)
{
return new org.w3c.www.protocol.http.HttpURLConnection(u);
}
}
/* END OF Handler.java */
Then build everything under src/classes/org/w3c/{util, www}.
Of these classes, only HttpURLConnection.java can be integrated into
the core as things stand (Handler.java will cause the build of javalib
to fail unless the Jigsaw classes have already been compiled, and they
won't without HttpURLConnection.class present) unless of course someone
at W3C wants to contribute the Jigsaw code... Daniel?
If this were the case, I would be willing to undertake this integration.
It shouldn't take too long but would greatly increase the size of the
distribution. Perhaps it is a good candidate for inclusion in the
proposed kaffe-contrib thingy?
Later,
Steve
