Category attributes default values updating

Question

Hi,
I'm developing an application that, upon upload of a file to the specified root folder(through the application), reads some values from a file, creates a folder structure based on those values, and moves the file in the bottom folder. Now, a predefined category should be attached to the file, to enable search by category attributes. My idea is to set the category as required on that bottom folder (or the first), and modify it's attribute default values, so that the file inherits them when moved in it. I have found mshannon's examples in some other thread ( Updating a document with category metadata using updateDocument(): error! ), the first one works only with files, not folders, and the second one doesn't work for me at all, I get an error:
javax.faces.el.EvaluationException: ORACLE.FDK.AggregateError:ORACLE.FDK.AggregateError
here is my code:
public static void updateAttributes() throws FdkException, RemoteException{
login();
FileManager fm = s_WsCon.getFileManager();
Item fajl = fm.resolvePath(prop.getProperty("userhome") + "/root folder/folder1/readme1.txt",
null);
long docID = fajl.getId();
NamedValue[] catInstAtr = new NamedValue[] {
new NamedValue("CUSTOM_138297", "changed value for att1"),
new NamedValue("CUSTOM_138299", "changed value for att2")
NamedValue[] catDef = new NamedValue[] {
new NamedValue(Options.UPDATE_CATEGORY_ID,new Long(139054)),
new NamedValue(Options.CATEGORY_DEFINITION_ATTRIBUTES, catInstAtr)
NamedValue[] docDef = new NamedValue[] {
new NamedValue(Options.CATEGORY_DEFINITION, catDef)
AttributeRequest[] reqAtr = new AttributeRequest[]{
new AttributeRequest(Attributes.DESCRIPTION, null)
fajl = fm.updateDocument(docID, docDef, reqAtr);
logut();
This example is (I think) only for updating on document level, but I could use a solution for folder-level updating, as I explained before. Can anyone help me?
Thanks,
Pedja

Pedja,
Here is my code to get category from Folder this is updated version from sample code TestCategory2.java
1. It will get the required category of a folder.
2. gets the internal category attribute names
3. get Category id if uploading file along with category attribute values OR
updating file and also updating previous category instance values..
