Oracle.mds.versioning.VersioningNotSupportedException: MDS-01900

Question

Hi people,
I'm trying set a label in my MDS to test customizzations in my application with this code:
public void meuMetodo() {
try {
MDSInstance mds =
(MDSInstance)ADFContext.getCurrent().getMDSInstanceAsObject();
VersionHelper vh = VersionHelper.get(mds);
Namespace[] validNamespaces = new Namespace[1];
Namespace pageNamespace =
Namespace.create("/tmp/filerepos1", NamespaceRestriction.CUSTOMIZATIONS);
validNamespaces[0] = pageNamespace;
vh.createLabel(string, null, validNamespaces);
} catch (MultipleLabelsException e) {
e.printStackTrace();
} catch (InvalidNamespaceException e) {
e.printStackTrace();
} catch (VersioningNotSupportedException e) {
e.printStackTrace();
} catch (LabelExistsException e) {
e.printStackTrace();
I create a jspx that receive my string and call this method, but when I run this the errors occurs:
oracle.mds.versioning.VersioningNotSupportedException: MDS-01900: None of the configured metadata stores support versioning.
