Can't use JMock to mimic facts

It is not possible to use objects, created by JMock, to assert into working memory, below is the test case:

===============================================
/**

• Defines methods used to access underlying storage
  */
  public interface ContentStorageInterface { public ResultsInterface search(QueryInterface query); }

===============================================

/**

• Implementation of searching for Lucene
  */
  public class LuceneQuery implements QueryInterface {

public LuceneQuery(String query, String field) {
}

/**

• @see java.lang.Object#equals(java.lang.Object)
  */
  @Override
  public boolean equals(Object obj) { if (obj == this) return true; if (!(obj instanceof LuceneQuery)) return false; return true; }

}

===============================================

/**

• Defines methods to use for searching
  */
  public interface QueryInterface {

}

===============================================

import java.util.Iterator;

/**

• Defines methods to use for managing search results
  */
  public interface ResultsInterface { public int getResultsCount(); public Iterator<Object> getResults(); }

===============================================

/**

• Defines helper methods for using in rules
  */
  public class RuleHelper {

public static final ResultsInterface search(
ContentStorageInterface content, String pattern, String column)

{ return content.search(new LuceneQuery(pattern, column)); }

}

===============================================

package sample;

rule "Verify_1"
when
content : ContentStorageInterface()
results : ResultsInterface( resultsCount > 0)
from RuleHelper.search(content,"pattern","column")
then
System.out.println( results );
end

===============================================
