Solr 3.1 ICU filters (error loading class)

[Demian Katz <de...@villanova.edu>]

Hello,

I'm interested in trying out the new ICU features in Solr 3.1.  However, when I attempt to set up a field type using solr.ICUTokenizerFactory and/or solr.ICUFoldingFilterFactory, Solr refuses to start up, issuing "Error loading class" exceptions.

I did see the README.txt file that mentions lucene-libs/lucene-*.jar and lib/icu4j-*.jar.  I tried putting all of these files under my Solr home directory, but it made no difference.

Is there some other .jar that I need to add to my library folder?  Am I doing something wrong with the known dependencies?  (This is the first time I've seen a lucene-libs directory, so I wasn't sure if that required some special configuration).  Any general troubleshooting advice for figuring out what is going wrong here?

thanks,
Demian

Thanks!  apache-solr-analysis-extras-3.1.jar was the missing piece that was causing all of my trouble; I didn't see any mention of it in the documentation -- might be worth adding!

Thanks,
Demian

make a 'lib' directory under your solr home (e.g. example/solr/lib) :
it should contain:
* icu4j-4_6.jar
* lucene-icu-3.1.jar
* apache-solr-analysis-extras-3.1.jar

Right, I placed my files relative to solr_home, not in it -- but obviously having a solr_home/lucene-libs directory didn't do me any good. :-)

I don't think you want to put them in solr_home, I think you want to put 
them in solr_home/lib/.  Or did you mean that's where you put them?
