Hi,
I tried to start the solr-4.0.0-BETA with tomcat-6.0.20 but does not work.
I copied the apache-solr-4.0.0-BETA.war to $TOMCAT_HOME/webapps. Then I copied
the directory apache-solr-4.0.0-BETA\example\solr to C:\home\solr-4.0-beta and
adjusted the file
$TOMCAT_HOME\conf\Catalina\localhost\apache-solr-4.0.0-BETA.xml to point the
solr/home to C:/home/solr-4.0-beta. With this configuration, when I startup
tomcat I got:
SEVERE: org.apache.solr.common.SolrException: Invalid luceneMatchVersion
'LUCENE_40', valid values are: [LUCENE_20, LUCENE_21, LUCENE_22, LUCENE_23,
LUCENE_24, LUCENE_29, LUCENE_30, LUCENE_31, LUCENE_32, LUCENE_33, LUCENE_34,
LUCENE_35, LUCENE_36, LUCENE_CURRENT ] or a string in format 'VV'
So I changed the line in solrconfig.xml:
<luceneMatchVersion>LUCENE_40</luceneMatchVersion>
to
<luceneMatchVersion>LUCENE_CURRENT</luceneMatchVersion>
So I got a new error:
Caused by: java.lang.ClassNotFoundException: solr.NRTCachingDirectoryFactory
This class is within the file apache-solr-core-4.0.0-BETA.jar but for some
reason classloader of the class is not loaded. I then moved all jars in
$TOMCAT_HOME\webapps\apache-solr-4.0.0-BETA\WEB-INF\lib to $TOMCAT_HOME\lib.
After this setup, I got a new error:
SEVERE: java.lang.ClassCastException:
org.apache.solr.core.NRTCachingDirectoryFactory can not be cast to
org.apache.solr.core.DirectoryFactory
So I changed the line in solrconfig.xml:
<directoryFactory name="DirectoryFactory"
class="${solr.directoryFactory:solr.NRTCachingDirectoryFactory}"/>
to
<directoryFactory name="DirectoryFactory"
class="${solr.directoryFactory:solr.NIOFSDirectoryFactory}"/>
So I got a new error:
Caused by: java.lang.ClassCastException:
org.apache.solr.spelling.DirectSolrSpellChecker can not be cast to
org.apache.solr.spelling.SolrSpellChecker
How can I resolve the problem of classloader?
How can I resolve the problem of cast of NRTCachingDirectoryFactory and
DirectSolrSpellChecker?
I can not startup the solr 4.0 beta with tomcat.
Thanks,
