retrieving nodes from a nested folder

Sandra_Donk

Hi all,

I want to retrieve documents from a nested folder. The depth of this folder is 5.

-Folder 1

- Folder 2

- Folder 3

- Folder 4

- Folder 5

- Document 1

- Document 2

To retrieve these document i use the method ListNodes this method use the objectid of the folder as input. So far so good. My question is how can i determine the objectid of folder5 as quick as possible?

When is use the method GetNodeByName(OTAuthentication, parentid, name) i have to give a parentid and the name of the folder. But this way i need to know the objectid of the folder 4 (parentid). To get the objectid of folder 4 i have to do the same trick. i have to know the parentid from folder 4 which is folder 3. This gives me the feeling that i have to start at folder 1 and make multiple calls to the method GetNodeByName to go deeper through the nested folders until i am at the folder 5.

There has to be another way to get right to the folder 5 but i am not that familiar with EWS, so is there a way to go direct to folder 5 without knowing it's objectid?

Thanks in advance.

Regards,

Dennis

Is the function "getNodeByPath" what you're looking for?

Hi Carsten,

Sounds like a good option, but how do i use this method. Lets say my path is the following:

Enterprise\Folder1\Folder2

i create a string[] with the following input:[] path = new string[2];"Folder1"; Thanks, Dennis

string

path[0] =

path[1] = "Folder2";

Node node = dm.GetNodeByPath(GetOtAuthentication(), 2000, path);

This isn't giving me any node. The 2000 in my method is the rootId so i think this should be the enterprise folder. Can you see what i am doing wrong. Is there any good SDK for the Service implementation?

The previous post is a mess because i copy past a few things let's try it again

Your code looks correct .. I have no idea what is going wrong.You may also try what happens if you call GetNodeByName (notGetNodeByPath!) with name parameter "Folder1:Folder2" (this is whatGetNodeByPath internally does, afaik).

That's right. GetNodeByPath uses the array of strings to construct a colon-delimited path and calls GetNodeByName.

Dennis, is an exception thrown when you call GetNodeByPath or is null returned?

thanks,

Hi Carsten and Scott,

I did a getnodebyname before, but this method wants a parentid (objectid) to search for the name in the correct folder. The GetNodeByPath is more than welcome because i can give an array of folder names instead of objectids. When i run my code i don't get an exception just null.

Hi, Dennis.

Both GetNodeByName and GetNodeByPath require an object ID (i.e. 2000 for the Enterprise Workspace in your sample) from which the name or path is relative.

It looks like your sample code is fine (as Carsten said earlier). The only thing that comes to mind is perhaps a typo in one of the Folder names?

thanks,

Scott

The documentation API for Java indicates that getNodeByPath accepts a String array but that does correct.

getNodeByPath takes the parent node id and a List<String> instead of String[]. So convert you String array to a List<String> and try it.

Right, there will be differences like that between the JavaDoc for the server-side API and the generated JAX-WS proxy classes. And of course there will be differences between the WCF proxies and the JAX-WS proxies. In this case WCF proxies are being used with C#.
