CrawlTool

[Rajesh Munavalli <fi...@gmail.com>]

Hi,
        I tried to create a separate crawler based on the CrawlTool class.
The code compiles fine but throws the following runtime exception. If I move
the same class into nutch package, it works fine. Does anyone know what I am
missing?

Thanks,
Rajesh
