一个indexwiter类，在命令行下，测试程序运行正常，对2460条记录的数据库的标题字段
做索引，用时15秒，下面是程序：
import cn.net.cetin.analysis.cn.ChineseAnalyzer;
import cn.net.cetin.index.IndexWriter;
import java.util.Date;
class IndexDB {
public static void main(String[] args) {
try {
Date start = new Date();
short[] fieldNos={(short)4,(short)5};
byte[] indexModes={(byte)0,(byte)0};
IndexWriter writer = new IndexWriter((short)2, fieldNos,indexModes,new ChineseAnalyzer());
writer.index();
writer.close();
Date end = new Date();
System.out.print(end.
getTime() - start.getTime());
System.out.println(" total milliseconds");
} catch (Exception e) {
e.printStackTrace();
System.out.println(" caught a " + e.getClass() +
"/n with message: " + e.getMessage());
}
}
}
写到jsp页面里是这样的：编译能通过，就是页面里只显示出来了背景图片，没结果！
