Logs are dependent on the servlet contianer you use -- ie: with the solr example, log messages are written to the console were you run "start.jar" and can be configured to point elsewhere based on how you configure jetty.
in your case it looks like you are using tomcat, so you'll want to check the tomcat logs directory -- probably for "catalina.out" if i remember correctly. : I have been making changes to my schema and unfortauntly I now get a error : when viewing my Solr tomcat admin page. : : The error doesnt seem to explain the problem: : HTTP Status 500 - Severe errors in solr configuration.
