Question

我最近将本地项目中的Rails升级到3.2.8，现在当我进行任何搜索时出现以下错误：

RSolr::Error::Http - 500 Internal Server Error

我已经将solr schema.xml更改为以前的版本，它仍然给我同样的错误。

我安装的宝石：

sunspot (2.0.0.pre.120720)
sunspot_rails (2.0.0.pre.120720)
sunspot_solr (2.0.0.pre.120720)

此外，solr错误日志显示以下内容：

Sep 5, 2012 9:24:50 PM org.apache.solr.core.SolrResourceLoader locateSolrHome
INFO: JNDI not configured for solr (NoInitialContextEx)

谢谢！

尝试删除solr文件夹并重新启动Solr。它应该重新生成solr/data和solr/conf个文件夹。然后重新索引，例如：

cd /path/to/rails/root
rm -r solr
rake sunspot:solr:run
rake sunspot:solr:reindex

另请注意，sunspot 2.0不适用于JRuby 1.7，只有1.6。

为什么在Ruby on Rails中使用Sunspot Solr时会出现NullPointerException？
