I have installed Solr in Tomcat on my Ubuntu box.

After making some changes to the schema.xml configuration file, I get the following error when accessing the web interface of Solr:

HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: false in null ------------------------------------------------------------- org.apache.solr.common.SolrException: QueryElevationComponent requires the schema to have a uniqueKeyField implemented using StrField at org.apache.solr.handler.component.QueryElevationComponent.inform(QueryElevationComponent.java:157) at org.apache.solr.core.SolrResourceLoader.inform(SolrResourceLoader.java:508) at org.apache.solr.core.SolrCore.(SolrCore.java:589) at org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:137) at org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:83) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:295) at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:422) at org.apache.catalina.core.ApplicationFilterConfig.(ApplicationFilterConfig.java:115) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4001) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4651) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:771) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:546) at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:637) at org.apache.catalina.startup.HostConfig.deployDescriptors(HostConfig.java:563) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:498) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1277) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:321) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053) at org.apache.catalina.core.StandardHost.start(StandardHost.java:785) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:445) at org.apache.catalina.core.StandardService.start(StandardService.java:519) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:581) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)

My question is: Where does this logfile reside? I looked at /var/log/tomcat6/ but there was nothing (just a few files with no relevant question). I couldn't find any Solr-related logfiles either.

Is it because logging is not enabled in Tomcat6 by default? If so - how do I enable it?

Thanks in advance.

Didn't find the log but managed to solve the problem by looking at the above snippet.

QueryElevationComponent requires the schema to have a uniqueKeyField implemented using StrField

In Ubuntu solr.log file resides at /var/log/ folder to see log file you can use following command:

tail -f /var/log/solr.log
