Questions about Solrj indexing/updateRequest API with regard to enabling HTTP Basic Auth inside Tomcat (HTTP POST method)

[Yuan Jerry]

Hi Solr User List,

I have started using Solrj (Solr and Solrj 4.1.0, and also 4.10.1) for sending 
indexing/update requests to Solr server that is being hosted inside Tomcat, and 
the security authentication HTTP BASIC auth is enabled in this Solr server 
web.xml.

(1) The client code looks like below:

String solrServerUrl = "http://localhost:8983/solr/core";;
String userName = "solr_admin";
String password = "solr_pwd";

DefaultHttpClient client = new DefaultHttpClient();
HttpClientUtil.setBasicAuth(client, userName, password);

HttpSolrServer solrServer = new HttpSolrServer(solrServerUrl, client);

SolrInputDocument doc = new SolrInputDocument();
doc.addField("id", "id_" + System.currentTimeMillis());
doc.addField("name", "Name_" + System.currentTimeMillis());
doc.addField("title", "Title_" + System.currentTimeMillis());

try {
       UpdateResponse updateResponse = solrServer.add(doc, 10000);
       ......
} catch (Exception ex) {
}

(2) The Solr server web.xml is configured with the following HTTP BASIC Auth 
configurations:

web.xml:

       <login-config>
              <auth-method>BASIC</auth-method>
              <realm-name>Solr</realm-name>
       </login-config>

       <security-constraint>
              <web-resource-collection>
                     <web-resource-name>Secured Solr Access</web-resource-name>
                     <url-pattern>/*</url-pattern>
              </web-resource-collection>
              <auth-constraint>
                     <role-name>solr_secure</role-name>
              </auth-constraint>
       </security-constraint>

(3) The Tomcat container has the following role defined for being used in the 
above security constraints:

tomcat-users.xml:

       <tomcat-users>
         <role rolename="solr_secure"/>
         <role rolename="manager-gui"/>
         <user username="solr_admin" password="solr_pwd" 
roles="solr_secure,manager-gui"/>
       </tomcat-users>

When I ran the above client code trying to add a single SolrDocument, and it 
always failed with the following exception:

org.apache.solr.client.solrj.SolrServerException: IOException occured when 
talking to server at: http://localhost:8983/solr/core

Are there any users out there that have used solrj APIs to conduct indexing / 
storing process for solr documents into Solr server that is configured with 
HTTP Basic Auth like above? If so, please let me know if you have encountered 
similar exceptions or there could be some issues with my configurations that 
are shown above. Your information would be highly appreciated in advance.
