Subject: [PATCH] jcifs-0.9.4 from tgz

Mon Jun 28 13:29:39 EDT 2004
jcifs-0.9.3 released

The  specification  of a port in the SMB URL has been fixed. Full workgroup
and  server  enumeration  was  also  broken.  JCIFS  can  now enumerate ALL
workgroups  and  servers.  The  NtlmHttpURLConnection class for negotiating
NTLM with HTTP clients has been updated to be more robust and support POST.
