>From the info you gave, its hard to tell. Can you look at src/plugin/indexer-solr/src/java/org/apache/nutch/indexwriter/solr/SolrIndexWriter.java and compare. Looking at a indexing plugin which works will help you figure if you missed something.
Also, had you added the entry for your plugin into nutch-site.xml -> "plugin.includes" property before running ? The default value is: <property> <name>plugin.includes</name> <value>protocol-http|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|indexer-solr|scoring-opic|urlnormalizer-(pass|regex|basic)</value> <description>Regular expression naming plugin directory names to include. Any plugin not matching this expression is excluded. In any case you need at least include the nutch-extensionpoints plugin. By default Nutch includes crawling just HTML and plain text via HTTP, and basic indexing and search plugins. In order to use HTTPS please enable protocol-httpclient, but be aware of possible intermittent problems with the underlying commons-httpclient library. </description> </property> On Mon, Jul 1, 2013 at 6:59 AM, Sznajder ForMailingList < bs4mailingl...@gmail.com> wrote: > I wrote a plugin implementing IndexWriter > > It compiles and creates the jar as requested. > > However, Nutch does not succeed to find my IndexWriter in its constructor: > > this.indexWriters = (IndexWriter[]) objectCache > .getObject(IndexWriter.class.getName()); > > After this call the indexWriters field is null... > > > > > > Where should I define that ? > > Best regards > Benjamin >
