I tried to get some services from the DefaultMetaDataResolver class. Since i
dont have following objects it is throwing nul pointer exceptions.
   * private MetadataRepository metadataRepository;
  * private StorageMetadataResolver storageResolver;

stack trace :
  java.lang.NullPointerException
    at
org.apache.archiva.metadata.repository.DefaultMetadataResolver.getRootNamespaces(DefaultMetadataResolver.java:122)

As deng mentioned those objects are injected by plexes by the
@plexus.requirement annotation. But here that annotation is commented. But
in components.xml  i saw those objects as reqiurements.

Here actually I want to know how do we inject those objects when we are
using that DefaultMetadataResolver class in another module.?


thankz.
