Description
The SolrConf class loader does not find indirectly used jars from external lib directories. This is a regression. It worked as of July 2, 2012, when I posted the most recent OpenNLP patch (LUCENE-2899). Something has broken since then.
This regression is true in both 4.x and the trunk. Both worked on July 2, 2012.
I have a project (the OpenNLP plugin) which uses jars from three places:
- solr/contrib/opennlp/src
- tokenizer and filter factories
- solr/contrib/opennlp/lib
- OpenNLP project libraries
- lucene/analysis/opennlp/src
- tokenizer and filter
SolrConf can only find the OpenNLP project jars when I add them to the solr.war libraries. It cannot find them from any of these directories:
solr/example/solr/lib solr/example/solr/collection1/lib solr/contrib/opennlp/lib
Here are the relevant config file entries. From solrconfig.xml:
<lib dir="../../../dist/" regex="apache-solr-opennlp-\d.*\.jar" /> <lib dir="../../../contrib/opennlp/lib" regex=".*\.jar" />
(yes, it needs to be three dot-dot-slash, not two. See SOLR-3624.)
From schema.xml:
<!-- OpenNLP all-in-one analyzer -->
<fieldType name="text_opennlp" class="solr.TextField" positionIncrementGap="
100"
>
<analyzer>
<tokenizer class="solr.OpenNLPTokenizerFactory"
sentenceModel="opennlp/en-test-sent.bin"
tokenizerModel="opennlp/en-test-tokenizer.bin"
/>
</analyzer>
</fieldType>
Here is the log. opennlp.tools.sentdetect.SentenceModel is a class in the OpenNLP jar.
