and here is my SolrServerHolder code.

public class SolrServerHolder {
    private static SolrClient concurrentSolrServer = null;
    private static HttpSolrClient solrServer = null;
    @SuppressWarnings("deprecation")
    private static HttpSolrServer httpServer = null;
    private static DefaultHttpClient client = null;

    private static synchronized void initHttpClient() {
        try {
            PoolingClientConnectionManager connManager = new PoolingClientConnectionManager();
            connManager.setDefaultMaxPerRoute(20); // Allow upto 20 connections for solr server
            connManager.setMaxTotal(1000);
            client = new DefaultHttpClient(connManager);
        } catch (Error e) {
            e.getMessage();
        }
    }

    private static synchronized void initConcurrentSolrServer() throws Exception {      
        if(client == null)
            initHttpClient();       

        UsernamePasswordCredentials defaultcreds = new UsernamePasswordCredentials("XXXX", "YYYY");
        client.getCredentialsProvider().setCredentials(
                new AuthScope("localhost", 
                        "8090", AuthScope.ANY_REALM),defaultcreds);

        concurrentSolrServer = new ConcurrentUpdateSolrClient("http://localhost:8090/solr/abc", client, 5000, 2);

    }

public static  SolrClient getConcurrentSolrServer() throws Exception {
        if(concurrentSolrServer == null)
            initConcurrentSolrServer();
        return concurrentSolrServer;
    }

}

and Here is my code which will trying to delete the data by query and throwing exception :

SolrClient server =SolrServerHolder.getConcurrentSolrServer();
server.deleteByQuery("id:65657575", 12000);
server.commit();

if i am trying to add docs to solr it is working perfectly Fine

SolrInputDocument docs = getDocs();
SolrClient server =SolrServerHolder.getConcurrentSolrServer();
server.add(abc);
server.commit();

I have refereed similar issues and solutions but it didn't help me.
