Subject Getting update/extract RequestHandler to work under Tomcat
Date Tue, 03 Nov 2009 00:37:39 GMT

Hoping someone might help with getting /update/extract RequestHandler to
work under Tomcat.

Error 500 happens when trying to access
http://localhost:8080/apache-solr-1.4-dev/update/extract/  (see below)

Note /update/extract DOES work correctly under the Jetty provided
example.

I think I must have a directory path incorrectly specified but not sure
where.

No errors in the Catalina log on startup - only this: 

	Nov 2, 2009 7:10:49 PM org.apache.solr.core.RequestHandlers
initHandlersFromConfig
	INFO: created /update/extract:
org.apache.solr.handler.extraction.ExtractingRequestHandler

Solrconfig.xml under tomcat is slightly changed from the example with
regards to <lib> elements:

  <lib dir="../contrib/extraction/lib" />
  <lib dir="../dist/" regex="apache-solr-cell-\d.*\.jar" />
  <lib dir="../dist/" regex="apache-solr-clustering-\d.*\.jar" />:

The \contrib and \dist directories were copied directly below the
"webapps\apache-solr-1.4-dev" unchanged from the example.

Im the catalina log I see all the "Adding specified lib dirs..." added
without error:
