Using SnowballPorterFilterFactory throws NoClassDefFoundError ------------------------------------------------------------- Key: HSEARCH-232 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-232 Project: Hibernate Search Issue Type: Bug Reporter: Hardy Ferentschik Assignee: Hardy Ferentschik Fix For: 3.1.0.Beta2 Trying to use SnowballPorterFilterFactory in @AnalyzerDef will currently throw the following exception: java.lang.NoClassDefFoundError: org/apache/solr/request/QueryResponseWriter at org.apache.solr.analysis.SnowballPorterFilterFactory.init(SnowballPorterFilterFactory.java:42) The problem is SnowballPorterFilterFactory contains a log statement using SolrCore.log.fine(). SolrCore itself has then a whole list of other import statements including QueryResponseWriter. Within Hibernate Search we use a custom/shrinked version of the solr jar which only contains the classes needed for analysis. QueryResponseWriter should of course not be required (see http://repository.jboss.org/maven2/org/hibernate/apache/lucene/solr/apach...). The problem does not occur when the full solr jar is used. We need to start a discussion with the solr developers regrading this logging issue. Example annotation causing the error: @AnalyzerDef(name="customanalyzer", tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class), filters = { @TokenFilterDef(factory = LowerCaseFilterFactory.class), @TokenFilterDef(factory = SnowballPorterFilterFactory.class,params = { @Parameter(name="language", value= "English") }), }) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
