But it seems like there should be a way to issue the equivalent of

        http://localhost:8983/solr/schema/version

which returns

   {
   "responseHeader":{
      "status":0,
      "QTime":4},
      "version":1.5}

from the server.  I know how to do it using HTTPGet in Android, but I can't use 
that in my desktop app because sometimes I'm connected to a local set of files 
using an embedded SolrJ server.  It seems silly to write a bunch of code to 
parse the files myself when Solr already does it so well.

There does not seem to be a request handler to use to issue such a call nor a 
direct API.

Has anyone ever gotten this information from the server using SolrJ?

This code works against a 4.4-SNAPSHOT server.  I believe that parts of 
the schema REST API are in 4.3.1, so this will likely work against that 
version too:

  String url = "http://server:port/solr/corename";;
  SolrServer server = new HttpSolrServer(url);
  SolrQuery query = new SolrQuery();
  query.setRequestHandler("/schema/version");
  QueryResponse response = server.query(query);
  float version = (float) response.getResponse().get("version");
  System.out.println(version);

Thanks,
Shawn
