package org.springframework.beans.factory does not exist error

Question

I try to implement a simple hello world program using Spring framework. I have tried the following example in Windows environment without using IDE. In Eclipse IDE, it works fine.
In Windows command line prompt, I get following error messages.

C:\Users\Vijay\Documents\javaex\ex1>javac -d . Test.java  
Test.java:3: error: package org.springframework.beans.factory does not exist

Please find the folder contents.

</beans>

I have put Spring core jar files in same folder.
JAVA_HOME and CLASS PATH looks fine. I couldn't figure out why import is failing.
It would be great if someone helps to find out what could have been wrong?
