I have written a plugin that extracts all the JavaScript URLs and returns them as outlinks. I would like to configure Nutch to take these outlinks and push these urls in the crawldb. Is there a way I can do that? If yes, I would like to know how I could do it. 2. How do I invoke this plugin? My logs show that the plugin is not invoked. My set up is as follows: Any advice would be gratefully appreciated. I am referring to http://florianhartl.com/nutch-how-it-works.html on what each job does.
