[infinispan-dev] Querying Infinispan -- Help Needed

Hi, I have a problem in getting through the querying feature of infinispan. I am using the technical preview listed in this wiki page<http://www.jboss.org/community/wiki/QueryingInfinispan>with the help of the sample code provided in the same page. I used the following properties for the second argument in QueryHelper Constructor. #hibernate.properties hibernate.search.default.directory_provider org.hibernate.search.store.FSDirectoryProvider hibernate.search.default.indexBase=/usr/vin/lucene/indexes This is my class for Hibernate Search @ProvidedId @Indexed public class Item { @Field private String name; @Field private String description; ...// getters and setters } I have included the @ProvidedId since QueryHelper instantiation validates the classes based on this annotation. *Note :: QueryHelper.validateClasses() -- This is to check that both the @ProvidedId is present and the the @DocumentId is not present. This is because don't want both of these 2 annotations used at the same time.* When I used the @Indexed annotation for the above class, it throws an exception while instantiating the QueryHelper. <Exception Snippet> java.lang.NullPointerException at org.hibernate.search.engine.DocumentBuilderIndexedEntity.init(DocumentBuilderIndexedEntity.java:151) at org.hibernate.search.engine.DocumentBuilderContainedEntity.<init>(DocumentBuilderContainedEntity.java:93) at org.hibernate.search.engine.DocumentBuilderIndexedEntity.<init>(DocumentBuilderIndexedEntity.java:128) at org.hibernate.search.impl.SearchFactoryImpl.initDocumentBuilders(SearchFactoryImpl.java:409) at org.hibernate.search.impl.SearchFactoryImpl.<init>(SearchFactoryImpl.java:119) at org.infinispan.query.backend.QueryHelper.<init>(QueryHelper.java:87) <Exception Snippet> When I removed that @Indexed annotation, QueryHelper got instantiated but it throwed some exception when it hits CacheQuery.getBasicQuery() method, where it forms lucene query string with the help of QueryParser. org.hibernate.HibernateException: There are no mapped entities. Don't forget to add @Indexed to at least one class. Please let me know if I missed anything here. Thanks in advance, Vinoth
