Basic Java - Packaging

I decided to post this question after trying to find an answer for it, and couldn't find one. I'm studying for OCJP and tried few simple codes. This is what I did and need to do.

  1. Created two .java sources, say TestOne.java, TestTwo.java [using notepad++]
  2. Created a directory named "package1" and placed the two sources in them.
  3. Both the source files have "package package1;" as their first statement.
  4. TestOne.java has one public class and one class with default access.
  5. TestTwo.java has one default class with an object of the default class in TestOne.java.
  6. The main method is in this default class in TestTwo.java. It tries to invoke a method in the referred object that was created, using TestOne.java default class.

So after all that was set up compiled TestOne.java then TestTwo.java by setting the flag "classpath" in javac [ javac -classpath ]. Complied. But when I tried to run it gave me an exception "Exception in thread "main" java.lang.NoClassDefFoundError". Does anyone know what's wrong ?

try this 

javac -d path cname.java

so write the code like this

javac -d c:\main testone.java javac -d c:\main testtwo.java

c:\main should exist in your pc

then while executing 

java -cp path pn.classname

so whichever class contains main (say test2)

java -cp c:\main package1.testtwo
