Re: Lucene Problems

Before I started to have the indexing failures, I had another problem, this time much more difficult to replicate.

About every 10 searches, I would get a "Bad Resource" error from LuceneGenerator. A simple reload of the page would give me the search hits I expected.

Can anyone think of a Cocoon cause for these problems, or should I get onto the Lucene team about them?

Do you have anymore detailed exception stack traces?

Now I have the indexing fixed, I have started getting this intermittent bug again, here is the stacktrace you asked for.

Incidentally, you can see from the fragment of my page, at the bottom of the stacktrace, that Lucene appeared to find 30 hits.

The actual Lucene exception appears in the 3rd chunk, I am CIncluding this search from an internal pipeline.

Thanks for your help

If you need help and this information is not enough, you are invited to read the cocoon faq.
If you still don't find the answers you need, can send a mail to the Cocoon users mailing list, remembering to

* specify the version of Cocoon you're using, or we suppose that you are talking about the latest version;
* specify the taglibs and sitemap components that are pertinent;
* specify the platform-operating system-version-servlet container version;
* send any pertinent error message;
* send pertinent log snippets;
* send pertinent sitemap snippets;
* send pertinent parts of the page that gives you problems.

For more detailed technical information, take a look at the log files in the log directory of cocoon, which is /WEB-INF/logs by default.
Logging configuration is by default in /WEB-INF/logkit.xconf.

If you think you found a bug, please report it to Apache's Bugzilla; a message will be sent to the developer mailing list.
