不索引或提取遠程文檔（.pdf .doc）

我使用Solr 3.1，Apache Tika 0.9和Solrnet 0.3.1來索引 docuent，如.doc和.pdf文件。不索引或提取遠程文檔（.pdf .doc）

我已經成功地索引和提取文件在本地使用此代碼

Startup.Init<Article>("http://k9server:8080/solr"); 
     ISolrOperations<Article> solr = ServiceLocator.Current.GetInstance <ISolrOperations<Article>>(); 
     string filecontent = null; 
     using(var file = File.OpenRead(@"D:\\solr.doc")){ 
        var response = solr.Extract(new ExtractParameters(file, "abcd1") { 
         ExtractOnly = true, 
         ExtractFormat = ExtractFormat.Text, 
      }); 
      filecontent = response.Content; 
     } 
     solr.Add(new Article() { 
       ID = "36", 
       EMAIL = "1234", 
       COMMENTS = filecontent, 
       PRO_ID = 256 
     }); 
     // commit to the index 
     solr.Commit();

但我面臨的問題從遠程使用相同的代碼提取或索引文件，我得到了錯誤：

The remote server returned an error: (500) Internal Server Error. 
SolrNet.Exceptions.SolrConnectionException was unhandled

你可以從遠程服務器發佈錯誤日誌嗎？這可能會給出一些提示，爲什麼它會生成500. – Gagravarr 2011-05-05 11:30:26

我發佈了錯誤日誌只是檢查它 – Dhaval950 2011-05-05 12:53:35

您的遠程服務器上的類路徑中的兩個不同版本的Apache POI的，這就是爲什麼你得到的例外，你看

您應該刪除POI的舊版本，並留下只是用附帶的新罐子SOLR/Tika。如果找不到它，請參閱POI FAQ以瞭解如何識別額外的jar。

如果它工作對當地的Solr實例，但不反對另一個實例，那麼其他實例可能未正確配置。

通過堆棧跟蹤判斷，似乎POI庫不正確（可能是錯誤的版本）。確保從Solr 3.1.0發行版中複製所有的Tika JAR。
