Querying Solr via Solrj: Basics

I am trying to query solr via solrj in Eclipse. I have tried the latest solrj wiki example:

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.params.ModifiableSolrParams;

import java.net.MalformedURLException;

public class SolrQuery2 {
  public static void main(String[] args) throws MalformedURLException, SolrServerException {
    SolrServer solr = new CommonsHttpSolrServer("http://localhost:8080/solr");

    // http://localhost:8080/solr/select/?q=outside
    ModifiableSolrParams params = new ModifiableSolrParams();
    params.set("qt", "/select");
    params.set("q", "outside");

    QueryResponse response = solr.query(params);
    System.out.println("response = " + response);
  }
}

However, I cant get past this error no matter what I do:

Exception in thread "main" java.lang.NoSuchMethodError: 
    org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

Next, I tried the cookbook example:

import java.util.Iterator;
import org.apache.solr.client.solrj.SolrQuery; //Error: The import org.apache.solr.client.solrj.SolrQuery conflicts with a type defined in the same file
import org.apache.solr.client.solrj.impl.CommonsHttpSolrServer;
import org.apache.solr.client.solrj.impl.XMLResponseParser;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;

public class SolrQuery {
    
      public static void main(String[] args) throws Exception {

          CommonsHttpSolrServer server = new CommonsHttpSolrServer("http://localhost:8080/solr");
          server.setParser(new XMLResponseParser());
          SolrQuery query = new SolrQuery();
          query.setQuery("document"); //Error: The method setQuery(String) is undefined for the type SolrQuery
          query.setStart(0); //Error: The method setStart(int) is undefined for the type SolrQuery
          query.setRows(10); //Error: The method setRows(int) is undefined for the type SolrQuery
          QueryResponse response = server.query(query); //Error: The method query(SolrParams) in the type SolrServer is not applicable for the arguments (SolrQuery)
          SolrDocumentList documents = response.getResults();
          Iterator<SolrDocument> itr = documents.iterator();
          System.out.println("DOCUMENTS");
          while(itr.hasNext()){
              SolrDocument doc = itr.next();
              System.out.println(doc.getFieldValue("id")+":"+doc.getFieldValue("content"));
          }
          
      }
    }

However, that example might be dated for the current api as I cant even import the SolrQuery library.

Does anyone have a quick boilerplate example that works?

Thank you in advance.

PS. I am running windows7 with tomcat7 and solr 3.5. All I am trying to do at this point is a basic query and get the results back in some kind of list, array, whatever. When I query: http://localhost:8080/solr/select/?q=outside in firefox, the results come back just fine.

Solution

Here is how I got Solrj (Solr 3.6) working on my Windows7 box with eclipse:

import java.net.MalformedURLException;

import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.impl.HttpSolrServer;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.params.ModifiableSolrParams;

public class SolrQuery {
  public static void main(String[] args) throws MalformedURLException, SolrServerException {
    SolrServer server = new HttpSolrServer("http://localhost:8080/solr");
        ModifiableSolrParams params = new ModifiableSolrParams();
        params.set("q", "1");

            QueryResponse response = server.query(params);

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

  }
}

I had to download additional jars (outside Solr of 3.6) for this to work: httpcomponents-client-4.2-beta1

In total, I needed 4 jars to get this working :

apache-solr-solrj-3.6.0.jar
httpclient-4.2-beta1.jar
httpcore-4.2-beta1.jar
httpmime-4.2-beta1.jar

Im not sure if my solution is considered a best practice in terms of boilercode, but it solves the issue of getting up on solrj w/ eclipse.
