public class AddIssue

   private final static Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore");

This is my code to apply a category to a node. itemId is the uuid of the node and categoryId is the uuid of the category.

Reference reference = new Reference(storeRef, itemId, null);
Predicate predicate = new Predicate(new Reference[]{reference}, null, null);
ArrayList<Reference> categoryList = new ArrayList<Reference>();
AppliedCategory appliedCategory = new AppliedCategory();
Reference catRef = new Reference(storeRef, categoryId, null);
categoryList.add(catRef);
appliedCategory.setCategories(categoryList.toArray(new Reference[0]));
appliedCategory.setClassification(Constants.createQNameString(Constants.NAMESPACE_CONTENT_MODEL, "generalclassifiable"));
AppliedCategory[] appliedCategories = new AppliedCategory[]{appliedCategory};
// Now classify the node
ClassificationServiceSoapBindingStub classificationService = WebServiceFactory.getClassificationService();
CategoriesResult[] result2 = classificationService.setCategories(predicate, appliedCategories);

Hi dongq

i would try your solution tomorrow….. i'll give a feedback if it would work… thanks for so long

just a little question at the moment.. i've not programmed a lot with alfresco webservices… how do i get the uuids of the node and the category?

thanks a lot

regards

If you don't know the uuid, you can use the path.
public Reference(
           org.alfresco.webservice.types.Store store,
           java.lang.String uuid,
           java.lang.String path)
The constructor for Reference will take either the uuid or the path.

Hi,
i've tried your code snipped right now.
it seems to be good but i got an error assigning the category….
it says could not resolve to a single node….
what is the path to the category?
i've got a category "Test" with a subcategory "Test2"

whats wrong with the following code!?

private final static Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore"); 
Reference catRef = new Reference(STORE, null, "cm:generalclassifiable/cm:Test/cm:Test2");
‍‍‍‍

Thanks a lot

I think the path is probably /cm:categoryRoot/cm:generalclassifiable/cm:Test/cm:Test2 .
You can use the classficationservice's getClassification and getChildCategories to iterate through the category hierarchy.

Hi dongq…. thanks for all your answers.. now everything works fine….

is it possible to run this code on a Application Server?!
i would crate a html form where i can choose title and the category and something else.
and on submittion of this form my code should be executed….. is this possible?

Thanks a lot.

[danisowa]

ok,
i think i should run my code as servlet.

but how can i manage to use for example org.alfresco.webservice.types.Store

my servlet reports an error….

please help me

…And…How Can I assign 2 or more categories to the Content?

[hitesh]

Just add one more Reference for your category , and add that reference to categoryList mentined in the above code…. that's it.
