not able to include package created by own in java

I have written a program that checks a data set and provides a result, i.e. if a climate condition is given for 1000 days as data set to the program it will find any deviation in the program and provide as result that major deviation.

package main;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URL;

import faster94.*;
import rules_agarwal.*;
import algo_apriori.*;
import context_apriori.*;
import itemsets.*;


public class MainTestAllAssociationRules {

    public static void main(String [] arg){

        ContextApriori context = new ContextApriori();
        try {
            context.loadFile(fileToPath("ds1.txt"));
        } 
        catch(Exception e)
        {
            e.printStackTrace();
        } 
        /*catch (IOException e) {
            e.printStackTrace();
        }*/
        context.printContext();


        double minsupp = 0.5;
        AlgoApriori apriori = new AlgoApriori(context);
        Itemsets patterns = apriori.runAlgorithm(minsupp);
        patterns.printItemsets(context.size());


        double  minconf = 0.60;
        AlgoAgrawalFaster94 algoAgrawal = new AlgoAgrawalFaster94(minconf);
        RulesAgrawal rules = algoAgrawal.runAlgorithm(patterns);
        rules.printRules(context.size());

    }

    public static String fileToPath(String filename) throws UnsupportedEncodingException{
        URL url = MainTestAllAssociationRules.class.getResource(filename);
         return java.net.URLDecoder.decode(url.getPath(),"UTF-8");
    }
}

The above is the main program. There are seven files and I have created by own package, but when I run this program as a whole I cannot run it. It complains that a package is missing. i have ready provided all the seven files.

Can any one be able to run those files?

Directory tree has to reflect package tree. So if you have a class in a package named main you class file must be in a directory named main under the working directory. So if you execute from bin/ your class must be in bin/main. Hope this helps

Edit

The directory tre has to look like this.
bin/
-----faster94/
--------------Classes or Subpackage
-----rules_agarwal/
-------------------Classes or Subpackage
-----algo_apriori/
------------------Classes or Subpackage
-----context_apriori/
---------------------Classes or Subpackage
-----itemsets/
--------------Classes or Subpackage
-----main/
----------MainTestAllAssociationRules and other classes or subpackages

To run this use java main.MainTestAllAssociationRules in the root (bin/) directory
