Get file list of Folder

[Former Member]

Hello!

I'm just a beginner in KM, that's why have some simple questions.

I want to get List of files in folder, like that list appear in "KM Content" in Administration.

What code will solve my problem?

Seems like I found solution:

ICollection currentFolder = null;
currentFolder =(ICollection) ResourceFactory.getInstance().getResource(rid,context);
IResourceList children = null;
children = currentFolder.getChildren();
children.get(i).getName().toString()

But can I get GUID of file? Can't find solution for this..

The GUID really isn't part of the KM resource, but assigned by a service (which you'll have to query). I think the service is called the IdMapper service, but I may be confusing it with something else.

Found Example:

import com.sapportals.wcm.service.urimapper.IUriMapperService;
IUriMapperService ums = UriMapperServiceFactory.getInstance();

But I can't find library that contents UriMapperServiceFactory.

(com.sapportals.wcm.service.urimapper.UriMapperServiceFactory)

Any body know where that lib is located? Or e-mail to me?

You need to get the instance from the service factor (see http://help.sap.com/javadocs/NW04S/current/km/com/sapportals/wcm/service/ServiceFactory.html).

Thanks, but I don't understand what should I do with ServiceFactory Instance after?

Hi,

about gettong the GUID from RID see my reply here: [https://www.sdn.sap.com/irj/sdn/thread?messageID=6077407#6077407|https://www.sdn.sap.com/irj/sdn/thread?messageID=6077407#6077407]

The required lib you can find on portal filesystem here:

\usr\sap\XXX\JCXX\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.netweaver.bc.rf.service\lib\bc.rf.global.service.urimapper_api.jar 

Hope that helps,

Romano

Thanks, But on this line raise exception:

IUriMapperService uriservice = (IUriMapperService )ResourceFactory.getInstance().getServiceFactory().getService("UriMapperService");

An exception occurred while processing a request for :

iView : N/A

Component Name : N/A

com.sapportals.wcm.service.urimapper.IUriMapperService.

Hi,

not sure (you should send the stackTrace from the defaultTrace.log) but maybe you have forgot to add the sharing reference to the portalapp.xml of your project:

...
<application>
  <application-config>
    <property name="SharingReference" value="knowledgemanagement"/>
  </application-config>
  <components>
...

Thanks, Romano Bodini. That is!

But now I have next problem:

uriMapperService don't have method like getRIDFromGuidRID

[Former Member · Accepted solution]

Hi Paul,

for sure it has...at least in my portal version...this works for me - I've tried:

      RID rid = RID.getRID("/documents/"); 
      IUriMapperService uriMapperService = (IUriMapperService) ResourceFactory.getInstance().getServiceFactory().getService("UriMapperService");
      RID guid = uriMapperService.getGuidRIDFromRID(rid); //  "493a20804adfb2be5ba2980b435501a8-989g75632safr4df7ga2980b894742a8";
      RID rid2 = uriMapperService.getRIDFromGuidRID(guid); // /documents
      response.write("RID:" + rid + ", GUID:" + guid + ", RID2:" + rid2);

What is your EP version?

Hi Paul,
What is your EP version?

I have Netweaver 7.0 SP09, EP6.0

Maybe I have old library(jar)? Can You e_mail me your lib jar?

Or Maybe file guid was embeded in newer SP of portal?

[Former Member · Accepted solution]

Paul,

I've sent you the JAR required. That portal version should work...in fact I work on an older one - EP6 SP19 or something like this ;o) - but I have found it also in the 7.0 library.

Romano

Romano Bodini, thanks very much!

Imported your lib, but necessary method didn't appear

I have no ideas now..

[Former Member · Accepted solution]

Uff

...impossible, check your mail - I'm sending you a testing project - try it and let me know...

Romano

[Former Member · Accepted solution]

Thanks! Your program compiled fine and methods exist!

It's kind of mysticism

Looks like some lib imported in my project overlaps. Didn't know if can be like that..

[Former Member · Accepted solution]

Glad to hear that...

...please mark this thread as solved - it will help others to find the information they need.
