     4安裝方法

    6     The protocol-smb plugins allows you to crawl Microsoft Windows shares. It implements
    7     the CIFS/SMB protocol which is commonly used on Microsoft OS. The plugin replicate the
    8     behaviour of the protocol-file over CIFS/SMB protocol. This plugin uses the JCifs library and also
    9     support all the properties from the JCifs library.
     61.  下載 protocol-smb 最新檔，解壓縮此檔，假定壓縮後的資料夾名稱為 $pro-smb-dir
    107
    11     You can find more information on the following site: http://jcifs.samba.org/
    12     The smb protocol syntax for crawling is as follow: smb://xxxxx (i.e. smb://server/share).
    13    
    14 B.  Installation

    16     1) Binaries only: 
     102. 將 $pro-smb-dir/build/plugins/內的 '''protocol-smb''' 資料夾 (內的 三個檔案 jcifs-1.3.0.jar  plugin.xml  protocol-smb.jar)
     11複製到  '''$nutch_home/plugin/''' 去，
    1712
    18  The protocol-smb files can be found in the ../plugins directory.
     133. 修改 $nutch_home/conf/nutch-site.xml
    1914
    20                                 Copy the "protocol-smb" to NUTCHHOME/build/plugins directory.

     23}}}
    2124
    22                         Put the "smb.properties" file in the NUTCHHOME/conf directory.
     254. 將 $pro-smb-dir/conf/smb.properties 複製到  $nutch_home/conf/，並設定數值
    2326
    24                         Configure the properties in "smb.properties" file
     275. url 格式為 smb://server/share
    2528
    26                         Enable the plugin by updating "nutch-site.xml" file found in NUTCHHOME/conf directory
     296. 進行 nutch 爬取

     66}}}
     67
     68 * 試著用以下方法解決：
     69{{{
     70#!txt
     71a) a short term solutions will be to installed the JCIFS jar
     72library found in protocol-smb folder in
     73JDKHOME/jre/lib/ext and (or) JREHOME/lib/ext
     74
     75b) After completing step a), if the exeception is still thrown
     76set the System properties by passing the following arguments
     77to the JVM:
     78
     79-Djava.protocol.handler.pkgs=jcifs
     80
     81c) You can set the property also in your Code for example if
     82you start Crawling with org.apache.nutch.crawl.Crawl
     83Add the following two lines. This will be the Same like in b)
     84public static void main(String args[]) throws Exception {
     85System.setProperty("java.protocol.handler.pkgs", "jcifs");
     86new java.util.PropertyPermission("java.protocol.handler.pkgs","read, write")
     87//and so on
     88
     89Also you can visit the FAQ page: http://jcifs.samba.org/src/docs/faq.html

     91
     92但是此warn 還是沒有解決，以至沒有入口點。於是到 http://jcifs.samba.org/src/docs/faq.html
     93
     94將jcifs專案單獨測試，

     152證明此jcifs 在我的電腦可以 work，因此是 protocal-smb 與 nutch 之間的問題
