NoHttpResponseException using Solrj to index

[Rui Vaz]

Hey I am trying to make a simple application using solrj to index documents.
I used the start.jar to start the Solr,. When I try to index a document to
Solr
I get the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/http/NoHttpResponseException

The exception occurs when I instantiate SolrServer (in orange):


public static void indexFilesSolrCell(File srcFile, String solrId)
    throws IOException, SolrServerException {

    String urlString = "http://localhost:8983/solr";;

    SolrServer solr = new HttpSolrServer(urlString);

    ContentStreamUpdateRequest up
      = new ContentStreamUpdateRequest("/update/extract");

I already import apache solr-solrj

Thank you,
