: class cast exceptions when I try to use my own similarity class, like this:
: public class TestSimilarity extends DefaultSimilarity
: {
: }
I have two alternate guesses
1) this may be a missleading error message, the real problem may be that
without a default constructor, it can't instantiate your Similarity.
2) this may be the behavior when the version of
Similarity/DefaultSimilarity you compile your class against don't
match the versions loaded by the JVM solr is running in (i think there
is a more specific JVM error when that happens though)
...to be safe, add a default constructor, and compile against the
lucene-core jar in the lib directory of the wolr release you are using.
: The jar with my class is located in example/ext, I get a class not found
: if I put it elsewhere. Should I be locating this jar elsewhere? Do I
you should create a "lib" directory in your solr.home directory and put
the jar there ... example/ext is where jars you want jetty to load in one
of the really low level class loaders live -- there's no need to put
anything SOlr specific there.
more details are in the solr home readme (example/solr/README.txt) and on
the SolrPlugins wiki...

: need to put lucene-nightly in the same directory? I also get a class
no, that's just because you tried to use example/ext which is loaded well
before hte solr.war, so in order for you to put your jar in example/ext,
everything else you jar refrences needs to be there as well.
