There are plenty of use-cases for having multiple cores. You may have two different schemas for two different kind of documents. Perhaps you are indexing content in multiple languages and you may want a core per language. In SolrCloud, a node can have multiple cores to support more than one shard on the same box. > > But now I get the Java-exception > > "java.lang.NoClassDefFoundError: org/apache/solr/core/SolrInfoMBean at > java.lang.ClassLoader.defineClass1(Native Method)" > > In the Tomcat-log file it is said additionally: "Caused by: > java.lang.ClassNotFoundException: org.apache.solr.core.SolrInfoMBean". > > My guess is, that within the new solrconfig.xml there are calls to classes > which aren't included correctly.

Would be great :) The Solr war file has all the classes it needs to startup and run (well except for some optional components like DataImportHandler etc) and the SolrInfoMBean is most definitely present in the war file. Enabling or disabling jmx has nothing to do with loading that class. It is very difficult to guess what's wrong with your setup this way. Why don't you try using the example jetty? It works and is well supported and optimized for Solr. -- Regards, Shalin Shekhar Mangar.
