As an example if you uploaded a document called 'abc' in document repository in

content Administrator->KM Content.

Navigate to documents folder then go to the context menu of your document abc.

Details->Settings->Properties

in the tabs click Access links tab and in the target url

copy from /irj

in the above example it would be,

'/irj/go/km/docs/documents/abc' . Use the url in your webdynpro code to access the document in KM folders

Note that you have proper permissions to that documents before accessing it.

Yes its possible. Go through:

Navigate through Knowledge Management repositories and folders from a WebDynpro Application using KM API - https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f02b492c-7d76-2a10-86aa-e11e8388...

Can you please provide me the sample code for accessing the KM document through webdynpro?

Hi Karthi,

if you want to access a file which is available in any km folder follow below steps.

1. check permissions. for testing purpose give full permissions to Everone.

2. create UI using webdynpro.

3. Place all required jar file which are required to use KM API in the build path.

4. Path always start from CM Repository directory. for instance in order to access Public documents folder. path would be: /documents/Public Documents/

3. in order to download/open existing file. below is code.

pathofkmfile=/documents/Public Documents/myfolder/myfile/

public final static InputStream getKmResource(String pathofkmfile){

try {

ResourceContext contex= new ResourceContext(WDClientUser.getCurrentUser().getSAPUser(););

IResourceFactory factory = ResourceFactory.getInstance();

RID rid =RID.getRID(pathofkmfile);

final IResource kmResource = factory.getResource(rid,contex);

if(kmResource==null){

throw new ResourceNotFoundException("KM Resource Not Found"+kmResource.getDisplayName());

}

return kmResource.getContent().getInputStream();

}

catch (Exception e) {

e.getStackTrace();

return null;

}

above method returns InputStream.

Once you get java.io.InputStream. you can manage to show or download or set this property of filedownload UI element.

Hope this will help you.
