有用过lucene的吗？？请问一下

[yangxiao_jiang]

import java.io.FileInputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;


import org.apache.lucene.analysis.SimpleAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;

public class IndexFiles {
//使用方法：: IndexFiles [索引输出目录] [索引的文件列表] ...
public static void main(String[] args) throws Exception {
String indexPath = args[0]; //索引输出目录 indexpath
IndexWriter writer;
//用指定的语言分析器构造一个新的写索引器（第3个参数表示是否为追加索引）
writer = new IndexWriter(indexPath, new SimpleAnalyzer(), false);
for (int i=1; i<args.length; i++)
{
System.out.println("Indexing file " + args[i]);
InputStream is = new FileInputStream(args[i]);
//构造包含2个字段Field的Document对象
//一个是路径path字段，不索引，只存储
//一个是内容body字段，进行全文索引，并存储
Document doc = new Document();
doc.add(Field.UnIndexed("path", args[i]));
doc.add(Field.Text("body", (Reader) new InputStreamReader(is)));
//将文档写入索引
writer.addDocument(doc);
is.close();
};
//关闭写索引器
writer.close();
}
}
显示的错误是
java.io.IOException: Index locked for write: Lock@C:\test\write.lock
at org.apache.lucene.index.IndexWriter.<init>(Unknown Source)
at org.apache.lucene.index.IndexWriter.<init>(Unknown Source)
at IndexFiles.main(IndexFiles.java:31)
Exception in thread "main"
应该怎么改？？

[yangxiao_jiang]

没有人会？？

那有人知道
NLS-SDK-2.1.0-Translations.zip能在什么地方下载到吗 ？？
是elipse2.1的多国语言支持

可能是少了：

writer.optimize();
writer.close();
因为没有对文件进行锁定。

Eclipse中文语言包下载：

http://download2.eclipse.org/downloads/drops/L-2.1.x%20Translations-200307021300/eclipse2.1.1-SDK-win-LanguagePackFeature.zip







下面是lucene自己带的demo：

class IndexFiles {
public static void main(String[] args) {
try {
long starttime = System.currentTimeMillis();

IndexWriter writer = new IndexWriter("index", new StandardAnalyzer(), true);
indexDocs(writer, new File(args[0]));
writer.optimize();
writer.close();
System.out.print(System.currentTimeMillis() - starttime);
System.out.println(" total milliseconds");

}
catch (Exception e) {
System.out.println(" caught a " + e.getClass() +
"\n with message: " + e.getMessage());
}
}

public static void indexDocs(IndexWriter writer, File file) throws Exception {
if (file.isDirectory()) {
String[] files = file.list();
for (int i = 0; i < files.length; i++) {
indexDocs(writer, new File(file, files[i]));
}
}
else {
System.out.println("adding " + file);
writer.addDocument(FileDocument.Document(file));
}
}
}
