RE: Unable to run two multicore Solr instances under Tomcat
Hi Erick, Thanks for the info, I figured out that it was a jar problem earlier today but I don't think it is an old jar. Both of the instances I ran included the extraction libraries and it appears that the problem is due to the xercesImpl-2.9.1.jar. If I remove the extraction tool jars from one of the instances, or even just the specific jar, then everything works as normal. Fortunately I only need the extraction tools in one of my instances so this work around is good for now. I can't see any old jars that would interfere, I will try and test this at some point on a clean install of 4.0 and see if the same problem occurs. -Original Message- From: Erick Erickson [mailto:erickerick...@gmail.com] Sent: Tue 13/11/2012 12:05 To: solr-user@lucene.apache.org Subject: Re: Unable to run two multicore Solr instances under Tomcat At a guess you have leftover jars from your earlier installation in your classpath that are being picked up.
