NPE on doc add through solrj

[wwwill]

I run this solrj code:

SolrServer server = new CommonsHttpSolrServer("http://localhost:8983/solandra");
Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
SolrInputDocument doc = new SolrInputDocument();
doc.addField("id", "1", 1.0f);
doc.addField("text", "this is some text for search", 10);
doc.addField("start", "20120220080000", 10);
doc.addField("end", "20120220081000", 10);
docs.add(doc);
server.add(docs);
server.commit();

and, I see this exception:

In SolandraIndexWriter line 241, either SolandraCoreInfo is null or AddUpdateCommand is null.

Any ideas why this might be happening?

It seems like it could be related to open issue #129.

Thanks,

I was not giving it a specific core. After I pushed a schema (and created a named core) and then connected to that with

SolrServer server = new CommonsHttpSolrServer("http://localhost:8983/solandra/myschema");

everything started to work. No more NPEs and adding/querying index work now. I followed the example of the reuters demo.
