Subject Re: [test] Jetty integration progress ? (was Re: [classlib] jetty based tests)
Date Tue, 08 Aug 2006 01:21:14 GMT
Alexei, sorry for my late reply.

It seems a big problem to me. :) I haven't find any solution yet.
Futhurmore, ftp server also needs to be substituted. Do you have any
suggestions?

Anyway, let's start from http server -- jetty. :) Any committers would like
to integrate jetty to Harmony? Thanks!
