Hi Tejas, Thanks for pointing out the problem. I have changed the package to kaqqao.nutch.selector and have also modified the package in java source files as package kaqqao.nutch.selector;
But I am still getting the ClassNotFound exception... please see attached images !!! Please note that I am using fresh Nutch 2.2 source without additional patch ... do I need to apply any patch to run this ? Thanks, Tony.
