Very much thanks for reply Erick !
Now ClassCastException is gone . It have corrected my fault .
So I am loading plugin correctly because is not giving me no class found
exception
in solrconfig.xml
<lib dir="${solr.install.dir:../../../..}/lib/myproject/lib"
regex=".*\.jar" />
in managed-schema
<fieldType name="text_reversed" class="solr.TextField">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<tokenizer class="com.skyrim.ReverseFilterFactory" />
</analyzer>
</fieldType>
Now I am facing new error that is following :
Caused by: org.apache.solr.common.SolrException: Error instantiating
class: 'com.skyrim.ReverseFilterFactory'
