That is a very odd cast exception to get. Do you want to open a JIRA
issue for this?
It looks like an odd exception because the call is:
NodeList nodes = (NodeList)solrConfig.evaluate(configPath,
XPathConstants.NODESET); // cast exception is we get an ArrayList rather
than NodeList
Which leads to:
Object o = xpath.evaluate(xstr, doc, type);
where type = XPathConstants.NODESET
So you get back an Object based on the XPathConstant passed. There does
not appear to be a value that would return an ArrayList.
Using XPathConstants.NODESET gets you a NodeList according to the XPath API.
I'm not sure what could cause this to happen.

Hi,
I was executing a simple example which demonstrates DistributedSearch.
example provided in the following link:
http://wiki.apache.org/solr/DistributedSearch
however, when i startup the server in both port nos: 8983 and 7574, i get
the following exception:
SEVERE: Could not start SOLR. Check solr/home property
java.lang.ClassCastException: java.util.ArrayList cannot be cast to
