Hello everybody
I m using NUTCH with SOLR and the result of solr searching as you know is in
XML format .
Because I want an HTML format for the response (like the result of NUTCH
searching result)
so I have tried to attach the xslt steelsheet to the response of SOLR with
passing this 2 variables wt=xslt&tr=example.xsl
while example.xsl is an included steelsheet to SOLR , but the response in
HTML was'nt very perfect .
So i have readen on the net that we can write an extension to the
QueryResponseWriter class like XMLResponseWriter (default)
and i m trying to build that .
I m proceeding like XMLREsponseWriter to create HTMLResponseWriter and i
have added this line <queryResponseWriter name="html"
class="org.apache.solr.
request.HTMLResponseWriter" /> in solr-config.xml
I have an error like this :
org.apache.solr.common.SolrException: Error loading class

It appears that the compiler doesn't found the class HTMLResponseWriter
Does anyone know where additionnals information about the class
HTMLResponseWriter must be added to remove this error ????????????????
