: I've copied TermsComponent and TermsParams from trunk into my own package : and Eclipse isn't reporting any build errors ... : SEVERE: java.lang.ClassCastException: : com.titanpublishing.solr.TermsComponent cannot be cast to : org.apache.solr.util.plugin.NamedListInitializedPlugin
TermsComponent extends SearchComponent which implements NamedListInitializedPlugin ... so if you are getting that error t run time, but you aren't getting any errors at compile time, that typically suggests that the classpath you compiled against isn't the same as your run time classpath -- there are probably differences in the NamedListInitializedPlugin between the version you are compiling against, and the version you are using at run time. -Hoss
