If you try to access solr with JSONP, you can get this error: “Fixing error talking to Solr: “Unexpected token :” over JSONP”.
The issue is that the Content-Type header is text/plain, rather than application/json.
The solution is to go into your solrconfig.json. comment out the section in queryResponseWriter, so it looks like this:
You also need to make sure these parameters are on the URL: wt=json&json.wrf=callback.
<queryResponseWriter name="json" class="solr.JSONResponseWriter"> <!-- <str name="content-type">text/plain; charset=UTF-8</str> --> </queryResponseWriter>
For the record, here is the error I got/:
