Hi,
I'm creating a custom request handler to return a list of live cores in
Solr.
On startup, I get this exception for each core:
Jul 31, 2009 5:20:39 PM org.apache.solr.common. SolrException log
SEVERE: java.lang.ClassCastException: LiveCoresHandler
at
org.apache.solr.core.RequestHandlers$1.create(RequestHandlers.java:152)

org.apache.solr.core.RequestHandlers.initHandlersFromConfig(RequestHandlers.java:169)
at org.apache.solr.core.SolrCore.<init>(SolrCore.java:444)
I've tried a few variations on the class definition, including extending
RequestHandlerBase (as suggested here:
http://wiki.apache.org/solr/SolrRequestHandler#head-1de7365d7ecf2eac079c5f8b92ee9af712ed75c2)
and implementing SolrRequestHandler directly.
I'm sure that the Solr libraries I built against and those I'm running on
are the same version too, as I unzipped the Solr war file and copies the
relevant jars out of there to build against.
Any ideas on what could be causing the ClassCastException? I've attached a
debugger to the running Solr process but it didn't shed any light on the
issue...
Thanks!
James
