         Environment: java version "1.5.0_11-p5"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-p5-root_04_jul_2007_17_12)

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

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