It appears that Axis does not provide any SOAP endpoints when JIRA is run behind https. When one requests /rpc/soap, eg:

https://support.atlassian.com/rpc/soap/exec sp_prepexec @P1 output, N'@P1 bigint,@P2 bigint,@P3 nvarchar(4000),@P4 nvarchar(4000),@P5 nvarchar(4000),@P6 nvarchar(4000),@P7 datetime,@P8 decimal(38,0)', N'INSERT INTO jiraaction (ID, issueid, AUTHOR, actiontype, actionlevel, actionbody, CREATED, actionnum) VALUES (@P1 , @P2 , @P3 , @P4 , @P5 , @P6 , @P7 , @P8 )', 12823, 10549, N'neala', N'comment', NULL, N'The main problem is that ''smart'' quotes are really "dumb" because only MS Word knows about them.', 'Dec 31 2005 1:53:17:257PM', NULL

One gets back:

"""
And now... Some Services

• null (wsdl)
  """

instead of the usual:

"""
And now... Some Services

• null (wsdl)
  o getUser
  o createUser
  o getComponents
  o createGroup
  o getGroup
  o login
  o getServerInfo
  o updateGroup
  """

The WSDL is correspondingly empty.
