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
