Re: Error loading class 'solr.DisMaxRequestHandler' after upgrade from solr350 to 431
This is probably a classpath problem. I'd guess that you have some old 3.5 jars laying around that are confusing the class loader. First thing I'd do is test with a clean 4.3 installation, then track down where the old jars are.
