i我使用Apache Lucene 4.9和NetBeans 7.2作为桌面应用程序。我已经创建了一个标准分析器，因此想要使用该分析器以创建IndexWriterConfig。但是InexWriterConfig给出了一个未找到类的错误
这是代码片段。
// create some index
StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_4_9);
System.out.println("index writer to be created1");
IndexWriterConfig IWConfig = new IndexWriterConfig(Version.LUCENE_4_9,analyzer);
这是IDE 给出的错误

有人能帮助解决方案吗
IntStreamFactory类驻留在lucene-codecs-4.9.0.jar、包org.apache.lucene.codecs.sep中。确保您的类路径中有这个jar。
