Httplib problem


I am using version 7.2.4 (b48) of Ignition Gateway. I do need httplib from Jython std library in my script. I am not able to do my work by Httplib is listed as a supported std library. I am trying out first GET - example in following example: … mples.html

With following error:

AttributeError: module ‘httplib’ has no attribute ‘HTTP’

When I try out to import httplib and print dir listing of this library, output is quite minimal when comparing regular Jython implementation:


import httplib
print dir(httplib)

[‘doc’, ‘file’, ‘name’, ‘socket’]

Regular Jython in Debian 5.0:

Jython 2.2.1 on java1.6.0_12
Type “copyright”, “credits” or “license” for more information.

import httplib
print dir(httplib)
[‘BadStatusLine’, ‘CannotSendHeader’, ‘CannotSendRequest’, ‘FakeSocket’, ‘HTTP’, ‘HTTPConnection’, ‘HTTPException’, ‘HTTPMessage’, ‘HTTPResponse’, ‘HTTPS’, ‘HTTPSConnection’, ‘HTTPS_PORT’, ‘HTTP_PORT’, ‘ImproperConnectionState’, ‘IncompleteRead’, ‘InvalidURL’, ‘LineAndFileWrapper’, ‘NotConnected’, ‘ResponseNotReady’, ‘SSLFile’, ‘SharedSocket’, ‘SharedSocketClient’, ‘StringIO’, ‘UnimplementedFileMode’, ‘UnknownProtocol’, ‘UnknownTransferEncoding’, ‘_CS_IDLE’, ‘_CS_REQ_SENT’, ‘_CS_REQ_STARTED’, ‘_UNKNOWN’, ‘all’, ‘doc’, ‘file’, ‘name’, ‘errno’, ‘error’, ‘mimetools’, ‘socket’, ‘test’, ‘urlsplit’]

I tried also import HTTP from httplib,


from httplib import HTTP

ImportError: cannot import name HTTP

Jython in Debian 5.0:

from httplib import HTTP
print dir(HTTP)
[‘doc’, ‘init’, ‘module’, ‘_connection_class’, ‘_http_vsn’, ‘_http_vsn_str’, ‘_setup’, ‘close’, ‘connect’, ‘debuglevel’, ‘getfile’, ‘getreply’, ‘putheader’]

What can be behind of this difference?

I checked out Java local cache in my workstation (\Application Data\Sun\Java\Deployment\cache\FPMI\script_lib). There are lot of python files, also file named There are implementations of full implementation of httplib, also class HTTP is implemented. This tries to import file named I noticed this file does not exist in this cache folder. I am not able to import mimetools also. Can it be root cause of original problem?

Yes, I think your troubleshooting is 100% right - that library is missing some dependent libraries. A quick look shows that those libraries (such as mimetools) themselvers require other ones, so it might be a bit of a mess for us to fix. I’ve made a bug ticket to look into the issue.

In the meantime take a look at the and functions. Do these cover what you wanted to do with the [tt]httplib[/tt] library?
