Exception in thread "main" java.lang.NoClassDefFoundError: org/Apache/commons/codec/DecoderException

Question

Ich versuche Querying Solr über Solrj

Hier ist mein Code

public class ReadFromSolr { 

public static void main(String[] args) throws MalformedURLException, SolrServerException 
{ 
    String url = "http://localhost:8983/solr"; 
     try{ 
    SolrServer server = new CommonsHttpSolrServer(url); 
    ModifiableSolrParams params = new ModifiableSolrParams(); 
     params.set("qt", "/select"); 
     params.set("q", "name"); 

      QueryResponse response = server.query(params); 

      System.out.println("response = " + response); 

     } 

     catch (MalformedURLException ex) { 
      ex.printStackTrace(); 
     } 
     catch (SolrServerException ex) { 
      ex.printStackTrace(); 
     } 


} 

}

und es gibt mir eine Ausnahme

PS. Ich habe die folgenden Gläser in meinem peoject bekam:

** Apache - commons-logging,
* Httpclient -4,2,
httpcore 4.2.1, slf4j - api 1.6.2,
Apache - solr - solrj -1.4.0 ***

Answer 1

Sie benötigen commons-codec.jar auf dem classpath.
