i rewrote the top jar section at

http://wiki.apache.org/solr/Solrj

and the following code then runs fine.

import java.net.MalformedURLException;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.impl.CommonsHttpSolrServer;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;

class TestSolrQuery {

	public static void main(String[] args) {
		
		String url = "http://localhost:8983/solr";
		SolrServer server = null;
		
		try { 
			server = new CommonsHttpSolrServer(url);
		} catch (MalformedURLException e) {
			System.out.println(e);
			System.exit(1);
		}
		
		SolrQuery query = new SolrQuery();
	    query.setQuery("*:*");
	    
	    QueryResponse rsp = null;
	    try { 
	    	rsp = server.query(query);
	    } catch(SolrServerException e) {
	    	System.out.println(e);
			System.exit(1);
	    }
	    
	    SolrDocumentList docs = rsp.getResults();
	    for (SolrDocument doc : docs) {
	    	System.out.println(doc.toString());
	    }
	}
}
