While pursuing the check with java 5, I tried to recreate the original problem. It took me a while, and I've discovered that underlying it all was a PEBKAC situation.
Before reading the docs, I tried putting my custom.jar into any and every directory that had jars. After reading the docs, I put it in example/solr/lib, but didn't remove it from example/ext. Whoops. Long story short, putting the custom.jar into example/solr/lib worked with java 5 and 6, so long as it wasn't also in example/ext. /dev -----Original Message----- From: Chris Hostetter [mailto:[EMAIL PROTECTED] Sent: Friday, February 09, 2007 3:34 AM To: solr-user@lucene.apache.org Subject: RE: Custom Tokenizer Sorry, one other thing to verify... did you see an INFO message like this logged at somepoint...
