Trouble creating a folder via web script

[mikew]

I’m attempting to write a very simple proof of concept stand-alone java program that communicates directly with a remote Alfresco server (3.0b) via web scripts. The program will, hopefully, recreate a local directory structure and upload local files into it. I am running into problems, specifically with http POST requests.

I am having no problems getting Alfresco tickets using login web script and no problem performing GET requests to:
GET /alfresco/service/api/path/{store_type}/{store_id}/{id}/descendants
to list the directory contents.

However, I am receiving a 400 response when I change the method to POST (either in code or via a form in an html page.)… with the message "Posting of media resource not supported"
POST /alfresco/service/api/path/{store_type}/{store_id}/{id}/descendants

I have been looking for guidance and inspiration here:
/alfresco/service/script/org/alfresco/repository/store/descendants.post

There are two js files listed:
File: org/alfresco/repository/store/descendants.post.atom.js
File: org/alfresco/repository/store/descendants.post.js

I'm guessing I'm hitting the latter (It issues a 400 response with the previously mentioned message) rather than the previous, which actually does the directory creation.

I'm also guessing I'm either taking the wrong approach entirely, or not constructing the POST request correctly (GET to the same URL returns a list of documents in the specified location).

My first question is: is this possible? If so, how would a POST request be constructed? I figure there must be some content in the POST (parameters: title or name, alf_ticket, typeId???)

Sorry if I'm missing something obvious, but any help or guidance would be appreciated.

Thanks for this discussion, its helped me.   

Can anyone say why I get a document instead of a folder when I try to create a folder with Firefox REST client as follows;

I POST to http://admin:admin@xxx.mydomain.org/alfresco/service/api/path/workspace/SpacesStore/Clinical%20Studi...

with just one Header

Content-type    application/atom+xml;type=entry

and a body of

<?xml version='1.0' encoding='utf-8'?>
<entry xmlns='http://www.w3.org/2005/Atom' xmlns:cmis='http://www.cmis.org/2008/05'>
<title>ThisShouldBeAFolder</title>
<summary>ThisShouldBeAFolder</summary>
<cmisbject>
<cmisroperties>
<cmisropertyString cmis:name='ObjectTypeId'>
<cmis:value>folder</cmis:value>
</cmisropertyString>
</cmisroperties>
</cmisbject>
</entry>

I see an ordinary bit of content created !

Just checked in the book, "Alfresco 3 Web Services" and the correct Atom XML to create a folder (for me in Alferesco Community 3.3g) is as follows.

(Just a bit confused as to why the recent XML posted above created a document instead of a folder)
(While I am at it,  non of this is RESTful, its just like a web service !)

<entry xmlns="http://www.w3.org/2005/Atom"
     xmlns:app="http://www.w3.org/2007/app"

I have error 404 : Not found

Help me please
============
UPDATE: i change link to: /alfresco/service/cmis/i/{id}/children

So i can create, but file, not folder. I am using: "<cmis:value>folder</cmis:value>\n"

Hi, when i uses your code, i have error 404.

Do you know any code to upload file which work in Android?

[alabbas]

I have the same problem with this code , do you fegar out the solution

[kaynezhang]

Why not use opencmis client

[fahad]

I am executing the above mentioned code but unable to resolve error 404 just appear because of parent folder not found. I aleady created a site "ABC" and a folder in that "folder123". Now I want to create a new folder inside "folder123". Can you guide me what will be the parentFolder in the code provided above?? How can I create a folder inside "forlder123". Your reply is encouraged

[shibu]

First of all, Thanx for this great post.
Code for create folder is working properly. But instead of creating folder it created a Binary File(Octet Stream). 

Please help. How to create folder instead of Binary File(Octet Stream)?
And can anybody tell , how can I create a JSON here instead of xml?
