If you just started to learn spring framework with the traditional approach by writing a helloworld program, then you might come across this:
BeanFactory factory; factory = new XmlBeanFactory(new InputStreamResource(new FileInputStream("hello.xml")));
here it shows the following error after run:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at org.springframework.beans.factory.support.Abstract BeanFactory.(AbstractBeanFactory.java:99)

This happens if you don't have commons-logging.jar in your classpath. You can download commons-logging.jar library from
http://commons.apache.org/downloads/download_logging.cgi
