RepositoryException - Reg

[Munaver Basha]

Hi ,
 
   I read all the content in the repository by using the below code

    Workspace ws = session.getWorkspace();
  QueryManager qm = ws.getQueryManager();
  QueryObjectModelFactory factory = qm.getQOMFactory();
  Selector source = factory.selector("nt:unstructured","unstructNodes");

  Column[] columns = null;

  Constraint constraint = null;
  Ordering[] orderings = null;
  QueryObjectModel queryObj = 
factory.createQuery(source,constraint,orderings,columns);QueryResult resultObj 
= queryObj.execute();

 
  when i executing the program i got the below issue

        javax.jcr.RepositoryException: no search manager configured for this 
workspace

  please help me to resolve this issue and please find my repository xml file.

 
Regards,
