Hi Tony, These issues stem from your environment not being correct. I, as many other, have been able to DEBUG and develop Nutch 1.7 and 2.x series from within Eclipse. As you are working with 2.x source, you may find it convenient to patch your dist with Tejas' Eclipse ant target and simply run 'ant eclipse' from within your terminal prior to doing a file, import, existing projects in to workspace from within Eclipse. I can guarantee you, the reason the tutorial is on the Nutch wiki is because as some stage, someone (many many people), somewhere have found it useful for developing Nutch in Eclipse. I don't want to sound like a baloon here, but your java security exceptions are not a problem with Nutch... it's your environment. hth
