Hi

pl refer the following link:
 http://wiki.apache.org/nutch/WritingPluginExample


To do after writing plugin and compiling it:
  - enlist u r new plugin in "plugin.includes" property present in 
nutch-site.xml
  - make sure that plugin's jar is present in directory specified by the 
property "plugins.folders" in nutch-site.xml
  - property "plugins.exclude" specifies rules for omission of plugins. 
Make sure u r plugin is not excluded by these rules. (Generally this 
property is not there, so no worries)
  - If u want to specify the alias of plugin , u will have to make an 
entry in parse-plugins.xml

To check whether, the plugin is getting loaded or not:
  - pl have a look at  org.apache.nutch.plugin.PluginRepository.java 
class. run this class with appropriate arguments
     - In the logs you should be able to see the name/s of folders in 
which plugins are looked
     - In the logs you should be able to see a detail list of 
extension-points and registered plugins . U shud see ur plugin in here :)
   
Bye
