nutch碰到failed with: Http code=403问题

做毕业设计。打算做一个校园网的搜索引擎。

下载了nutch1.2,然后做了一些配置试用了一下。

第一步：在解压后的nutch1.2目录里面新建urls目录，然后在其目录下新建url.txt文件，然后在文件中写入我

要抓取网站的网址，http://www.ujs.edu.cn/

第二步：在nutch1.2目录下新建logs目录，拿来存放日志文件。然后在下面新建test.log空白文件。

第三步：进入conf目录，编辑nutch-site.xml文件，这个文件主要配置你的spider的一些信息。

我的nutch-site.xml内容如下

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>
<property>
<name>http.agent.name</name>
<value>mynutch</value>
<description>test
</description>
</property>
<property>
<name>http.agent.description</name>
<value>spider</value>
<description> spider
</description>
</property>
<property>
<name>http.agent.url</name>
<value>http://www.xxx.com </value>
<description>http://www.xxx.com
</description>
</property>
<property>
<name>http.agent.email</name>
<value>MyEmail</value>
<description>[email protected]
</description>
</property>
</configuration>

第四步：编辑conf下crawl-urlfilter.txt文件，找到“# accept hosts in MY.DOMAIN.NAME”

这一行，然后把这一行下面紧接的一行改为"+http://www.ujs.edu.cn"

第五步：我用的是ubuntu,所以进入shell,cd入nutch1.2目录，然后执行抓取命令：

bin/nutch crawl urls/url.txt -dir crawled >logs/test.log

过了一分钟，就结束了抓取，但是却没有抓取到任何数据，日志如下：

发现里面出现了fetch of http://www.ujs.edu.cn/ failed with: Http code=403, url=http://www.ujs.edu.cn/错误

我尝试了好几次都是这样，但是在浏览器中，打开http://www.ujs.edu.cn是能正常打开的，403错误表示没有权限读取

内容，我不明白为什么会出现这样的原因。网上搜了一下，也没搜到什么。谁能告诉我，我哪里弄错了？
