Overwriting a File in the KM using web dynpro

Question

Hello,
im using the createresource method to upload files into the km using web dynpro.
(using the following tutorial: https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70a60afe-d576-2a10-68bf-9ce3988dc39e )
however, if i try to upload a file which is already there, it doesnt overwrite it, instead it throws an exception without any additiona info.
is there any way of doing this?
many thanks,
Eli.

Hi,
first check, if the resource exists, then decide to create or update content:
    IResource resource = (ResourceFactory.getInstance().getResource(rid, ctx));
    ICollection aCollection=(ICollection)resource;
    // get new resource RID
    RID newResRid = RID.getRID(repository+RID.PATH_SEPARATOR+resourceName);
    // try to find the resource
    IResource newResource = (ResourceFactory.getInstance().getResource(newResRid, ctx));
    if(newResource!=null)  {
      // does exist - update content
      newResource.updateContent(content);
    else  {
      // does not exist - create
      newResource = aCollection.createResource(resourceName, null, content);
Hope that helps,
