使用lucene建立索引的问题

zhangbo198294 2006-02-17 11:17:12

IndexFiles indexFiles=new IndexFiles();
File file = new File(request.getRealPath("1"));
IndexWriter writer= new IndexWriter(request.getRealPath("myindex"), new StandardAnalyzer(), true);
indexFiles.addIndex(writer,file);
writer.optimize();
writer.close();

我每次尽力新索引的时候会覆盖掉旧的索引库但覆盖时就出错了?_r.cfs我自己手动删也删不掉除非把TOMCAT关闭才可以删索引库应该是被Lock 请问怎么解锁?
