Running a Program in JDeveloper using Command Prompt

Question

Hi,
I downoladed Oracle JDeveloper 10g. I had written a simple java class called Echo. java. I want to run the file using command prompt. My JDK has the following path:
F:\Sowmya
My java file has the following path:
F:\Sowmya\jdev\mywork\1\1\src\pkg1
So, in order to compile the file, I gave the following command:
F:\Sowmya\jdk\bin>javac F:\Sowmya\jdev\mywork\1\1\src\pkg1\Echo.java
It worked and the Echo.class file was created.
But, when I tried to run the file using the following command,
F:\Sowmya\jdk\bin>java F:\Sowmya\jdev\mywork\1\1\src\pkg1\Echo
Iam getting the following error:
Exception in thread "main" java.lang.NOClassDefFoundError: F:\Sowmya\jdev\mywork\1\1\src\pkg1\Echo
This didnt work either:
F:\Sowmya\jdk\bin>java F:\Sowmya\jdev\mywork\1\1\classes\pkg1\Echo
Iam getting the same error.
Can any one please help me regarding this.
Thank you,
Sowmya.

Yes, my class contains a main. It runs if I click run in JDeveloper. But, there is no output displayed. The following is the code:
public class Echo {
public static void main (String[] args) {
for (String s: args) {
System.out.println(s);
}
