You have to add the dependencies commons-logging from Apache Commons. The current version will work "commons-logging-1.1.1"

added commons-logging-1.1.1 .......

Basically you have to add 3 libraries:

commons-httpclient-3.1.jar (v4.0+ will not work)
commons-logging-1.1.1.jar
commons-codec-1.4.jar

done that
still following exception!!!!!!!!!! ::
.UnknownHostException: api.search.yahoo.com
