Looks like, it doesn't matter, how I tried to make my package into Java, it is not working.
Anyone can tell me a good reference to build the package from scratch (I tried a few, and didn't work). I am using window system. I used the approach is given at: https://cwiki.apache.org/confluence/display/MAHOUT/BuildingMahout and also this blog http://shuyo.wordpress.com/2011/02/01/mahout-development-environment-with-maven-and-eclipse-1/ I apparently, succeed to build the project, and all steps went through (SUCCED) and no error were generated. As I mentioned, I am using Mahout 0.9, I was not able to do the same using Mahout 0.5,0.6, 0.7 or other versions. At this point, I just need to experiment in local window machine, rather than running at amazon System or Hadoop machine.
