[jira] [Created] (SLING-2343) query.json Internal Server Error
(500)
query.json Internal Server Error (500)
--------------------------------------
Key: SLING-2343
URL: https://issues.apache.org/jira/browse/SLING-2343
Project: Sling
Issue Type: Bug
Components: Servlets
Affects Versions: Servlets Get 2.1.2
Environment: JDK 1.6
Reporter: Róbert Csákány
I've created a node type:
<ajanlom = 'http://ajanlom.hu/ajanlom/1.0'>
<nt = 'http://www.jcp.org/jcr/nt/1.0'>
<sling = 'http://sling.apache.org/jcr/sling/1.0'>
[ajanlom:ownerOrganization] > nt:unstructured
There is several thousand nodes typed ajanlom:ownerOrganization. When I iterate over the QueryManager results with same query it works fine.
When I type the following URL:
http://localhost:8080/content.query.json?queryType=xpath&statement=/jcr:root/partner//element(*,ajanlom:ownerOrganization)
I get the following exception:
[{

[jira] [Resolved] (SLING-2343) query.json Internal Server Error
(500)
Posted by "Róbert Csákány (Resolved JIRA)" <ji...@apache.org>.

Róbert Csákány resolved SLING-2343.
-----------------------------------
Resolution: Not A Problem
I've found the problem. It was a corruption in Jackrabbit's lucene index that causes item not foud by UUID. I've deleted the lucene indexes and everything become ok when Sling restarted and Jackrabbit reindexed nodes.
