Subject Question about extending a response writer
Date Thu, 17 Dec 2009 15:13:30 GMT
Hi,

I'm pretty new solr internals, but have been experimenting with good
results... up to now!

What I'm trying to do is make it possible for the mlt docs to have their own
custom fl, separate from the main docs fl. I'm only interested in the ruby
response at this point. So the only way I've found to do this is to create a
new query response writer, which extends the ruby response writer and make a
few changes:

http://gist.github.com/258797

This class compiles fine. I put my "mlt-ruby-response-writer.jar" within my
solr-home/lib dir, and registered the response writer. Solr starts up
without errors.

... but when I run it within Solr I get an error:

class org.apache.solr.request.MLTRubyResponseWriter$MLTRubyWriter
cannot access its superclass org.apache.solr.request.RubyWriter

java.lang.IllegalAccessError: class
org.apache.solr.request.MLTRubyResponseWriter$MLTRubyWriter cannot
access its superclass org.apache.solr.request.RubyWriter

Anyone have an idea to what I might be doing wrong? Why would I be able to
compile, but then get a runtime error like that? Is this a classpath thing?

Oh, the error occurs when I make a request and specify the wt, which I named
"mltrb".

Thanks,
Matt
