Subject problem
Date Thu, 21 Jun 2007 13:03:02 GMT

I am getting null pointer exception here, I think the code is correct 
then what is the problem

public Node getBlogEntryNode(String blogTitle, Session session)
            throws BlogApplicationException {
        if (_logger.isDebugEnabled())
            _logger.debug("Entering JackrabbitBlogEntryDAO.getNode() "
                    + blogTitle);
        Node blogEntry;
        try {
            Workspace workSpace = session.getWorkspace();
   
            QueryManager queryManager = workSpace.getQueryManager();

            StringBuffer queryStr = new StringBuffer("//blogEntry[@title 
= '");
            queryStr.append(blogTitle);
            queryStr.append("']");
       
            Query query = queryManager.createQuery(queryStr.toString(),
                    Query.XPATH);
           
               
            QueryResult queryResult = query.execute();
                         

            NodeIterator queryResultNodeIterator = queryResult.getNodes();
                           
           
           
           
        blogEntry = null;
            while (queryResultNodeIterator.hasNext()) {
                blogEntry = queryResultNodeIterator.nextNode();
            }
        } catch (InvalidQueryException e) {
            throw new BlogApplicationException(e);
        } catch (RepositoryException e) {
            throw new BlogApplicationException(e);
        }
        if (_logger.isDebugEnabled())
            _logger.debug("Exiting JackrabbitBlogEntryDAO.getNode() "
                    + blogEntry);
        return blogEntry;
    }
