KM Std Properties via API: can be done!

Question

Hi guys,
This is to let you know that <b>std resource properties</b> (created by, created on, changed by, changed on, content length, ...) <b>can indeed be set using KM API's</b>.
Maybe this is not great surprise to someone, but it is for me, that after reading this <a href="https://www.sdn.sap.com/irj/sdn/thread?threadID=25606">thread</a> was very very scared...
Well, here's the code that worked for me on EP 6 SP 16 (honestly I don't see any serious reason for which it shouldn't be running on EP5 and EP7 as well... believe me: I decompiled a lot):
final String cmadmin = "cmadmin_service";
context = factory.getServiceContext(cmadmin);
com.sapportals.portal.security.usermanagement.IUser puser = context.getUser();
puser.setTransientAttribute("--km-change-systemproperties--", new Boolean(true));
Basically, create a context with the std service user cmadmin_service, and then set its "km-change-systemproperties" trasient attribute to true. Done!
For <i>the rest of the story</i> (how to set properties, etc), see KM API documentation under IResource interface or search SDN with "km api properties".
Cheers,
Alex

Hi Alex
Thanks for the reply. Here is the code:
Folder Structure:
documents
     testfolder
         Folder 1
            Some files here
        Folder 2
             Empty
         Folder 3
              Some more files here
try{
     String rLocationtest = "/documents/testfolder" ;
     IResourceContext c = ResourceFactory.getInstance().getServiceContext("cmadmin_service");
     IUser user = c.getUser();
     user.setTransientAttribute("--km-change-systemproperties--", new Boolean(true));
     ICollection collection = (ICollection)ResourceFactory.getInstance().getResource(RID.getRID(rLocationtest),c);
     loopFolder(collection,c,response);
catch(Exception e){
    e.printStackTrace();
public void loopFolder(ICollection collection, IResourceContext c, IPortalComponentResponse response){
try{
         IResourceList resList = collection.getChildren();
      IResourceListIterator resItr = resList.listIterator();
          while(resItr.hasNext()){
     IResource restemp = resItr.next();
     if(restemp.isCollection() && LinkType.NONE.equals(restemp.getLinkType())){
          loopFolder((ICollection)restemp,c,response);
IPropertyName modifiedByPropertyName = new PropertyName("http://sapportals.com/xmlns/cm","modifiedby");
IPropertyName createdByPropertyName = new PropertyName("http://sapportals.com/xmlns/cm","createdby");
//get the properties          
  IProperty resMProperty = restemp.getProperty(modifiedByPropertyName);
  IProperty resCProperty = restemp.getProperty(createdByPropertyName);                    
//get mutable properties
IMutableProperty mutableModifiedByProperty = resMProperty.getMutable();
IMutableProperty mutableCreatedByProperty = resCProperty.getMutable();               
//set mutable properties
mutableModifiedByProperty.setStringValue("Administrator");
mutableCreatedByProperty.setStringValue("Administrator");
//set the resource with new properties
restemp.setProperty(mutableModifiedByProperty);
restemp.setProperty(mutableCreatedByProperty);
response.write("Changed modified and created");
}// End of while
}catch(Exception e){
     e.printStackTrace();
  }//End of catch
         } //End of loopFolder
It updates only createdBy field and not the other one. If I modify one at a time instead of two, it works fine.
Thanks
