> With the remote spi connection, it seems that the inner/outer join doesn't work with
the result.getNodes() function.
> My code : 
> Repository repository = JcrUtils.getRepository(jcrUrl); 
> Session session = repository.login( new SimpleCredentials("admin", "admin".toCharArray()));
> String expression = ...;
> QueryManager queryMgr = session.getWorkspace().getQueryManager();
> Query query = queryMgr.createQuery(expression,Query.JCR_SQL2);
> QueryResult result = query.execute();
> Node node = result.getNodes().nextNode();
> Query1 :
> select node.* from [nt:unstructured] as node
> Return one element.
> Query2 :
> select node.* from [nt:unstructured] as node
> left outer join [nt:file] as file on ischildnode(file, node)
> left outer join [nt:resource] as filecontent on ischildnode(filecontent, file) 
> Doesn't return any element :
> java.util.NoSuchElementException
>     at org.apache.jackrabbit.jcr2spi.query.NodeIteratorImpl.nextNode(NodeIteratorImpl.java:110)
> The second query should return at least one element due to left outer join.
> A solution is to use ( work with both query )
> Node node = result.getRows().nextRow().getNode("node");
